NEW QUESTION # 29
What would happen if you choose not to proactively reboot the instance before the scheduled maintenance due date?
- A. The instance is either reboot-migrated or rebuilt in place for you.
- B. You will receive another notification to reboot within the next 14 days.
- C. You will receive another notification to reboot within the next 7 days.
- D. The instance will get terminated.
Answer: A
Explanation:
In OCI, if you choose not to proactively reboot your instance before the scheduled maintenance due date, the system will handle the maintenance automatically to ensure that the instance remains operational.
Reboot-Migration or Rebuild in Place: If you don't reboot the instance yourself, OCI will automatically perform a reboot-migration or rebuild in place for the instance. This ensures that the instance is moved to new hardware or updated without your intervention, maintaining uptime and applying necessary updates or fixes.
Impact on Instance: The exact action taken (reboot-migration or rebuild in place) depends on the type of maintenance required. However, either action will temporarily interrupt the instance, typically involving a reboot, but the instance's data and configuration will be preserved.

NEW QUESTION # 32
Which compute capacity type would you select to meet these requirements?
- A. Capacity reservation
- B. Dedicated host
- C. Preemptible capacity
- D. On-demand capacity
Answer: D
Explanation:
On-demand capacity is the compute capacity type in Oracle Cloud Infrastructure (OCI) that allows you to provision and use compute instances whenever needed, without any long-term commitment. This flexibility is ideal for various workloads, including development, testing, and production environments, where immediate availability and scalability are crucial.
Key Points:
On-Demand Capacity: On-demand compute instances provide users with the flexibility to spin up instances as required and only pay for the time the instances are running. This model is most suitable for workloads with unpredictable usage patterns or short-term requirements.
Flexibility and Scalability: With on-demand capacity, you can quickly scale your resources up or down based on your application's needs, ensuring that you only pay for the resources you actually use.
No Commitment: Unlike reserved capacity, on-demand capacity does not require any long-term commitment or upfront payment, making it an attractive option for organizations looking to avoid capital expenditures.
Reference:
Oracle Cloud Infrastructure Documentation: OCI Compute Pricing
Oracle Cloud Infrastructure Documentation: Compute Instance Lifecycle
Explanation of Incorrect Options:
A . Capacity reservation: This option allows you to reserve capacity in advance, ensuring that resources are available when needed. It's ideal for predictable workloads but may not be as cost-effective for fluctuating demands.
B . Preemptible capacity: Preemptible instances are a lower-cost option where instances can be terminated by OCI if resources are needed elsewhere. This is suitable for non-critical workloads that can tolerate interruptions.
D . Dedicated host: Dedicated hosts provide physical servers for your exclusive use, offering isolation and predictable performance. This option is more suitable for workloads requiring dedicated resources or compliance needs.
Thus, Option C: On-demand capacity is the correct choice for most general-purpose workloads needing flexibility and immediate availability without long-term commitment.
NEW QUESTION # 33
Why was SSH still possible after port 22 was removed from the Security Lists?
- A. The VNIC of that compute instance is attached to a Cluster Network.
- B. The VNIC of that compute instance is attached to a Network Security Group (NSG).
- C. The VCN where that compute instance resides still has a route rule.
- D. The VCN where that compute instance resides still has an Internet Gateway.
Answer: B
Explanation:
Even after removing port 22 from the Security Lists, SSH was still possible because the Virtual Network Interface Card (VNIC) of the compute instance is attached to a Network Security Group (NSG).
NSGs: NSGs provide a more flexible and granular way to manage security rules compared to Security Lists. They allow you to apply security rules directly to VNICs associated with resources such as compute instances. If an NSG allows traffic on port 22, SSH will still be possible, regardless of the Security List settings.

NEW QUESTION # 34
Which Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) policy is invalid?
- A. Allow group 'Default'/'A-Developers' to create volumes in compartment Project-A
- B. Allow dynamic-group 'Default'/'FrontEnd' to manage instance-family in compartment Project-A
- C. Allow any-user to inspect users in tenancy
- D. Allow group 'Default'/'A-Admins' to manage all-resources in compartment Project-A
Answer: C
Explanation:
In Oracle Cloud Infrastructure (OCI), Identity and Access Management (IAM) policies are used to control access to resources. The policy in option C is invalid because "any-user" is not a valid principal in OCI IAM policies. OCI policies can only grant permissions to groups or dynamic groups, but not to arbitrary users.
Here's an explanation for each option:
A . Allow dynamic-group 'Default'/'FrontEnd' to manage instance-family in compartment Project-A: This is valid. It grants the dynamic group 'FrontEnd' the ability to manage instances within the Project-A compartment.
B . Allow group 'Default'/'A-Admins' to manage all-resources in compartment Project-A: This is valid. It provides full administrative access to all resources in the Project-A compartment for the 'A-Admins' group.
C . Allow any-user to inspect users in tenancy: This is invalid because OCI does not allow the use of "any-user" in policies. You must specify a valid group or dynamic group to define permissions.
D . Allow group 'Default'/'A-Developers' to create volumes in compartment Project-A: This is valid. It permits the 'A-Developers' group to create volumes in the Project-A compartment.

NEW QUESTION # 35
Which TWO are key benefits of setting up Site-to-Site VPN on Oracle Cloud Infrastructure (OCI)?
- A. When setting up Site-to-Site VPN, it creates a private connection that provides consistent network experience.
- B. When setting up Site-to-Site VPN, customers can configure it to use static or dynamic routing (BGP).
- C. When setting up Site-to-Site VPN, customers can expect bandwidth above 2 Gbps.
- D. When setting up Site-to-Site VPN, OCI provisions redundant VPN tunnels.
Answer: B,D
Explanation:
Setting up a Site-to-Site VPN on Oracle Cloud Infrastructure offers several key benefits related to connectivity and reliability:
Static or Dynamic Routing (BGP): OCI allows customers to configure Site-to-Site VPN with either static routing or dynamic routing using Border Gateway Protocol (BGP). This flexibility enables customers to choose the routing method that best suits their network configuration and requirements.
Redundant VPN Tunnels: OCI automatically provisions redundant VPN tunnels when you set up a Site-to-Site VPN. These redundant tunnels ensure high availability and fault tolerance, so if one tunnel fails, traffic can continue to flow through the other tunnel without interruption.
Bandwidth Considerations: While the VPN provides a reliable connection, it typically does not exceed 2 Gbps in bandwidth. Higher bandwidth connections usually require FastConnect.
Private Connection: The VPN does create a secure and private connection between on-premises data centers and OCI, but it does not inherently provide a consistent network experience in the way that a dedicated connection like FastConnect does.

- A. You can keep adding parts as long as the total number is less than 10,000.
- B. Each part can be as large as 50 GIB.
- C. You do not need to split the object into parts.
- D. You do not have to commit the upload after uploading all parts.
Answer: A,B
Explanation:
When performing a multipart upload using the Multipart Upload API in Oracle Cloud Infrastructure (OCI) Object Storage, the following points are true:
C . Each part can be as large as 50 GiB: OCI allows each part of a multipart upload to be up to 50 GiB in size. This enables the efficient uploading of large objects in smaller, manageable parts.
D . You can keep adding parts as long as the total number is less than 10,000: The Multipart Upload API supports up to 10,000 parts for a single object. This allows the upload of very large objects by dividing them into multiple parts.
Incorrect Statements:
A . After uploading all parts, you must commit the upload to finalize the multipart upload and combine all parts into a single object.
B . The object must be split into parts before uploading when using the Multipart Upload API.

NEW QUESTION # 37
Which of the following is a valid RFC 1918 CIDR prefix that can be used for creating an Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN)?
- A. 10.0.0.0/8
- B. 192.168.0.0/16
- C. 192.268.0.0/24
- D. 0.0.0.0/0
Answer: A,B
Explanation:
RFC 1918 defines IP address ranges that are reserved for private networks, which cannot be routed on the public internet. In Oracle Cloud Infrastructure (OCI), these private IP address ranges can be used to create Virtual Cloud Networks (VCNs). The valid RFC 1918 CIDR prefixes include:
192.168.0.0/16: A private IP range often used in home networks.
10.0.0.0/8: A large private IP range commonly used in enterprise networks.
Invalid Options:
B . 0.0.0.0/0: This CIDR represents all IP addresses and is not a valid private IP range.
C . 192.268.0.0/24: This is not a valid IP address range as the octet "268" is outside the allowable range of 0-255.

NEW QUESTION # 38
A financial firm is designing an application architecture for its online trading platform that should have high availability and fault tolerance. What should the architect do to avoid any costly service disruptions and ensure data durability?
- A. Create a new Object Storage bucket in another region and configure recycle policy to move data every 5 days.
- B. Create a lifecycle policy to regularly send data from the Standard to Archive storage.
- C. Copy the Object Storage bucket to a block volume.
- D. Create a replication policy to send data to a different bucket in another OCI region.
Answer: D
Explanation:
For an online trading platform requiring high availability and fault tolerance, it's critical to ensure data durability and avoid any costly service disruptions. In Oracle Cloud Infrastructure (OCI), Object Storage is often used to store critical data, such as transaction logs or user data, due to its scalability, durability, and reliability.
Option B is the most suitable approach for ensuring data durability and availability across regions. Here's why:
Cross-Region Replication (CRR): OCI offers a feature called Cross-Region Replication for Object Storage. This feature allows you to automatically and asynchronously replicate objects in a bucket from one OCI region to another. This setup ensures that even if one region experiences a failure, the data is still available in another region, thereby meeting the requirements for high availability and fault tolerance.
Data Durability: By replicating data to another region, you protect against regional outages. OCI guarantees 99.95% availability for replicated data, which is critical for a financial firm's trading platform where data consistency and durability are paramount.
Disaster Recovery: With data replicated in another region, the trading platform can quickly switch to using the data in the secondary region in case of a disaster in the primary region. This setup significantly reduces recovery time objectives (RTO) and ensures business continuity.
Reference:
Oracle Cloud Infrastructure Documentation: Cross-Region Replication for Object Storage Oracle Whitepaper: High Availability and Disaster Recovery in Oracle Cloud Infrastructure Explanation of Incorrect Options:
Option A: Creating a new Object Storage bucket in another region and configuring a recycle policy to move data every 5 days does not provide real-time data availability or the fault tolerance required for a financial application. Recycle policies are intended for managing the lifecycle of data, not for high availability or disaster recovery.
Option C: While lifecycle policies are useful for moving less frequently accessed data to a more cost-effective storage tier (e.g., from Standard to Archive), they do not address cross-region redundancy or real-time availability, which are critical for this use case.
Option D: Copying an Object Storage bucket to a block volume is not a recommended practice for ensuring data durability and fault tolerance. Block volumes are used for persistent storage attached to compute instances, and copying object storage data to block volumes does not achieve the same level of redundancy and cross-region availability as replication policies.
Thus, Option B is the correct and most efficient method for ensuring high availability and fault tolerance in this scenario.
NEW QUESTION # 39
Which OCI Object Storage tier is suitable for storing the backup to minimize cost while meeting the requirements of immediate accessibility and retention of 31 days?
- A. Auto-Tiering tier
- B. Standard tier
- C. Infrequent Access tier
- D. Archive tier
Answer: C
Explanation:
The Infrequent Access tier in OCI Object Storage is suitable for storing backups that need to be immediately accessible and retained for a specific period, such as 31 days, while also minimizing costs. This tier offers a balance between cost and accessibility, charging lower storage costs compared to the Standard tier but still allowing quick access to the data.
Use Case: The Infrequent Access tier is designed for data that is not frequently accessed but must remain readily available when needed, making it ideal for backup storage.

Oracle Cloud Infrastructure Documentation: Object Storage Tiers
NEW QUESTION # 40
Which components are required for establishing remote peering between two Virtual Cloud Networks (VCNs) in Oracle Cloud Infrastructure (OCI)?
- A. Two VCNs with overlapping CIDRS in different regions, a virtual private network (VPN) gateway attached to each VCN, and a direct connection between the VPN gateways.
- B. Two VCNs with nonoverlapping CIDRS in the same region, a dynamic routing gateway (DRG) attached to each VCN, and a direct connection between the DRGs.
- C. Two VCNs with nonoverlapping CIDRS in different regions, a dynamic routing gateway (DRG) attached to each VCN, a remote peering connection (RPC) on each DRG, and a connection established between the RPCs.
- D. A single VCN with nonoverlapping CIDRS in each region, a dynamic routing gateway (DRG) attached to each VCN, and a direct connection between the DRGS.
Answer: C
Explanation:
Remote peering in Oracle Cloud Infrastructure allows two VCNs in different regions to communicate securely. To establish remote peering, the following components are required:
Two VCNs with Nonoverlapping CIDRs:
The CIDR blocks of the two VCNs must not overlap. This is crucial to avoid routing conflicts and ensure that traffic is correctly routed between the VCNs.
Dynamic Routing Gateway (DRG) Attached to Each VCN:
A DRG is a virtual router that provides a path for traffic between the VCN and networks outside the VCN, such as other VCNs via remote peering, on-premises networks, or other cloud services. Each VCN needs its own DRG.
Remote Peering Connection (RPC):
An RPC is a specialized connection on the DRG used specifically for remote peering. You need to create an RPC on each DRG associated with the VCNs you wish to peer.
Connection Between RPCs:
Finally, a connection must be established between the RPCs of the two DRGs. This connection facilitates the secure and private exchange of traffic between the VCNs over Oracle's backbone network.
Incorrect Options:
Option A involves a single VCN, which does not fulfill the requirement of remote peering between two VCNs.
Option B involves overlapping CIDRs and VPN gateways, which are incorrect for remote peering.
Option C suggests peering within the same region, which would be considered local peering rather than remote peering.
Relevant OCI Documentation:
OCI Remote VCN Peering
Dynamic Routing Gateway (DRG) Overview
These resources provide a detailed guide on configuring remote peering in OCI, ensuring secure and effective communication between VCNs across regions.
NEW QUESTION # 41
Which TWO statements are NOT correct regarding the Oracle Cloud Infrastructure (OCI) burstable instances?
- A. Baseline utilization is a fraction of each CPU core.
- B. Burstable instances are charged according to the baseline OCPU.
- C. If the instance's average CPU utilization is below the baseline, it can burst above the baseline.
- D. Burstable instances cost less than regular instances.
Answer: B,D
Explanation:
The following statements about OCI burstable instances are NOT correct:
A . Burstable instances cost less than regular instances: This is incorrect because burstable instances are not necessarily cheaper; the cost depends on the baseline utilization. While they allow for cost efficiency when running at a lower CPU baseline, they can become more expensive if frequently bursting above the baseline.
B . Burstable instances are charged according to the baseline OCPU: This is incorrect because burstable instances are billed based on actual OCPU usage, which includes both baseline and burst usage. If an instance frequently operates above its baseline, the cost will reflect this higher usage.
Correct Concepts:
C . Burstable instances can temporarily use more CPU than their baseline if the average CPU utilization is below the baseline.
D . Baseline utilization is a fraction of each CPU core, which determines the level of consistent performance available without bursting.

Oracle Cloud Infrastructure Documentation: Burstable Instances
NEW QUESTION # 42
What would be the total meteredBytes shown by the File Storage service after the hourly update cycle is complete when you overwrite 0.5 GB of a 1 GB file?
- A. 1.5 GB
- B. 0.5 GB
- C. 2.5 GB
- D. 1 GB
Answer: A
Explanation:
In Oracle Cloud Infrastructure (OCI) File Storage, when you overwrite a portion of a file, the service does not immediately reclaim the space occupied by the previous version of the file. The total meteredBytes reflects both the original data and the new data written.
Scenario Explanation: You start with a 1 GB file. When you overwrite 0.5 GB of this file, the file system retains both the 0.5 GB of the original file and the new 0.5 GB you wrote.
Calculation: The original 1 GB file contributes 1 GB to meteredBytes. When 0.5 GB is overwritten, the total usage becomes 1.5 GB (1 GB original + 0.5 GB new).
Thus, after the hourly update cycle, the total meteredBytes shown by the File Storage service will be 1.5 GB.

What is a key advantage of utilizing administrator roles for access control within OCI IAM identity domains?
- A. Simplify access management by eliminating policy creation
- B. Offer a wider range of permission combinations
- C. Provide granular control over user access to specific compartments
- D. Can be used to grant access to resources outside the identity domain
Answer: A
Explanation:
In Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM), administrator roles play a significant role in managing access:
Simplification of Access Management: Utilizing administrator roles allows you to simplify access management by eliminating the need to create complex IAM policies manually. These roles come with predefined permissions that cover common administrative tasks, reducing the effort needed to manage access controls.
Granular Control: While administrator roles provide a broad range of permissions, they may not offer the same level of granularity as custom policies.
Other Benefits:
Offer a wider range of permission combinations (A): While custom policies can offer more specific combinations, administrator roles are designed to cover a broad range of tasks.
Granting Access Outside Identity Domain (C): Administrator roles are generally scoped to their identity domain and do not provide cross-domain access.
Granular Control (D): Although administrator roles simplify management, custom policies are typically used when granular control over specific compartments or resources is needed.

Which statement is NOT correct regarding the Oracle Cloud Infrastructure (OCI) File System snapshots?
- A. Snapshots are accessible under the root directory of the file system at .snapshot/name.
- B. Before you can clone a file system, at least one snapshot must exist for the file system.
- C. Even if nothing has changed within the file system since the last snapshot was taken, a new snapshot consumes more storage.
- D. Snapshots are a consistent, point-in-time view of your file systems.
Answer: C
Explanation:
In OCI File Storage, snapshots are point-in-time, read-only copies of a file system that do not immediately consume additional storage beyond the space needed to track changes.
Incorrect Statement: The statement that a new snapshot consumes more storage even if nothing has changed is incorrect. Snapshots are space-efficient; they only consume additional storage as changes are made to the file system after the snapshot is taken. If no changes are made between snapshots, the storage consumption remains minimal.
Correct Statements:
B . Before cloning a file system, at least one snapshot must exist, as the clone operation relies on this snapshot to create a copy.
C . Snapshots are accessible under the .snapshot directory, allowing users to view and restore files from specific snapshots.
D . Snapshots provide a consistent, point-in-time view of the file system, ensuring data integrity.

NEW QUESTION # 48
What happens to the performance level of a volume when it is detached from an instance?
- A. The performance level is adjusted to Lower Cost (0 VPUs/GB).
- B. The performance level is adjusted to Balanced.
- C. The performance level is adjusted to Higher Performance.
- D. The performance level remains unchanged.
Answer: A
Explanation:
In Oracle Cloud Infrastructure (OCI), when a block volume is detached from an instance, its performance level is automatically adjusted to the "Lower Cost" tier, which provides 0 VPUs (Volume Performance Units) per GB. This adjustment helps reduce costs when the block volume is not actively being used by a compute instance.
Key Points:
Volume Performance Levels: OCI offers various performance tiers for block volumes, including "Higher Performance," "Balanced," and "Lower Cost." These tiers determine the level of IOPS (Input/Output Operations Per Second) and throughput available to the volume.
Automatic Adjustment: When a block volume is detached from an instance, OCI automatically optimizes the cost by switching the volume to the "Lower Cost" performance tier. This tier offers minimal performance, suitable for data that is not actively accessed.
Cost Management: This automatic adjustment is beneficial for managing costs, as it prevents users from incurring unnecessary charges for higher performance levels when the volume is not in use.
