DATA ENCRYPTION
Protect customer data at-rest and in-transit in a way that allows customers to meet their security and compliance requirements for cryptographic algorithms and key management The Oracle Cloud Infrastructure Block Volume service always encrypts all block volumes, boot volumes, and volume backups at rest by using the Advanced Encryption Standard (AES) algorithm with 256-bit encryption.
By default all volumes and their backups are encrypted using the Oracle-provided encryption keys. Each time a volume is cloned or restored from a backup the volume is assigned a new unique encryption key.
The File Storage service encrypts all file system and snapshot data at rest. By default all file systems are encrypted using Oracle-managed encryption keys. You have the option to encrypt all of your file systems using the keys that you own and manage using the Vault service.
Object Storage employs 256-bit Advanced Encryption Standard (AES-256) to encrypt object data on the server. Each object is encrypted with its own data encryption key. Data encryption keys are always encrypted with a master encryption key that is assigned to the bucket. Encryption is enabled by default and cannot be turned off. By default, Oracle manages the master encryption key.
NEW QUESTION 58
Which Oracle Cloud Infrastructure service allows you to run code without provisioning any underlying infrastructure resources?
- A. Oracle Functions
- B. Oracle Container Engine for Kubernetes
- C. Storage Gateway
- D. Compute service
Answer: A
Explanation:
Explanation
Oracle Functions is a fully managed, multi-tenant, highly scalable, on-demand, Functions-as-a-Service platform. It is built on enterprise-grade Oracle Cloud Infrastructure and powered by the Fn Project open source engine. Use Oracle Functions (sometimes abbreviated to just Functions) when you want to focus on writing code to meet business needs.
The serverless and elastic architecture of Oracle Functions means there's no infrastructure administration or software administration for you to perform. You don't provision or maintain compute instances, and operating system software patches and upgrades are applied automatically.
NEW QUESTION 59
Which kind of scaling is supported by virtual machines in Oracle Cloud Infrastructure Compute service?
- A. Only scaling in
- B. Scaling up or down, and scaling in or out
- C. Only scaling out
- D. Only scaling up or down
Answer: B
Explanation:
Explanation
To change the shape of an OCI Instance
You can change the shape of a virtual machine (VM) instance without having to rebuild your instances or redeploy your applications. This lets you scale up your Compute resources for increased performance, or scale down to reduce cost.
Autoscaling lets you automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.
As load increases, instances are automatically provisioned: the instance pool scales out. As load decreases, instances are automatically removed: the instance pool scales in.

NEW QUESTION 64
Which statement is correct regarding the oracle cloud infrastructure Compute services?
- A. You can attach a maximum of one public to each compute instance
- B. When you stop a compute instance, all data on the boot volume is lost
- C. You can launch either virtual machines or bare metal instances
- D. You cannot attach a block volume to a compute instance
Answer: C
Explanation:
Explanation
Oracle Cloud Infrastructure offers both bare metal and virtual machine instances:
Bare Metal: A bare metal compute instance gives you dedicated physical server access for highest performance and strong isolation.
Virtual Machine: A virtual machine (VM) is an independent computing environment that runs on top of physical bare metal hardware. The virtualization makes it possible to run multiple VMs that are isolated from each other. VMs are ideal for running applications that do not require the performance and resources (CPU, memory, network bandwidth, storage) of an entire physical machine.
An Oracle Cloud Infrastructure VM compute instance runs on the same hardware as a bare metal instance, leveraging the same cloud-optimized hardware, firmware, software stack, and networking infrastructure.

NEW QUESTION 69
Which OCI Identity and access management capability helps you to organize multiple users into teams?
- A. Dynamic Groups
- B. Policies
- C. Groups
- D. Users
Answer: C
Explanation:
Explanation
IAM Group is A collection of users who all need the same type of access to a particular set of resources or compartment.
IAM DYNAMIC GROUP is A special type of group that contains resources (such as compute instances) that match rules that you define (thus the membership can change dynamically as matching resources are created or deleted). These instances act as "principal" actors and can make API calls to services according to policies that you write for the dynamic group.
NEW QUESTION 70
You run 5 Oracle Cloud Infrastructure (OCI) Virtual Machine instances on an OCI dedicated virtual host. How will this deployment be billed?
- A. Only the dedicated virtual machine host will be billed
- B. All 5 instances will be billed on the basis of the number of OCPUs
- C. The dedicated virtual machine host all 5 instances, and the boot volume of each instance will be billed
- D. The dedicated virtual machine host and the boot volumes of each instance will be billed
Answer: D
Explanation:
Explanation
You must create a dedicated virtual machine host before you can place any instances on it. When creating the dedicated virtual machine host, you select an availability domain and fault domain to launch it in. All the VM instances that you place on the host will subsequently be created in this availability domain and fault domain.
You also select a compartment when you create the dedicated virtual machine host, but you can move the host to a new compartment later without impacting any of the instances placed on it. You can also create the instances in a different compartment than the dedicated virtual machine host, or move them to difference compartments after they have been launched.
You are billed for the dedicated virtual machine host as soon as you create it, but you are not billed for any of the individual VM instances you place on it. You will still be billed for image licensing costs if they apply to the image you are using for the VM instances.

NEW QUESTION 72
Which should you use to distribute Incoming traffic between a set of web servers?
- A. Dynamic Routing Gateway
- B. Load Balances
- C. Autoscallng
- D. Internet Gateway
Answer: B
Explanation:
Explanation
The Oracle Cloud Infrastructure Load Balancing service provides automated traffic distribution from one entry point to multiple servers reachable from your virtual cloud network (VCN). The service offers a load balancer with your choice of a public or private IP address, and provisioned bandwidth.
A load balancer improves resource utilization, facilitates scaling, and helps ensure high availability. You can configure multiple load balancing policies and application-specific health checks to ensure that the load balancer directs traffic only to healthy instances. The load balancer can reduce your maintenance window by draining traffic from an unhealthy application server before you remove it from service for maintenance.
HOW LOAD BALANCING WORKS:
The Load Balancing service enables you to create a public or private load balancer within your VCN. A public load balancer has a public IP address that is accessible from the internet. A private load balancer has an IP address from the hosting subnet, which is visible only within your VCN. You can configure multiple listeners for an IP address to load balance transport Layer 4 and Layer 7 (TCP and HTTP) traffic. Both public and private load balancers can route data traffic to any backend server that is reachable from the VCN.
1) Public Load Balancer
To accept traffic from the internet, you create a public load balancer. The service assigns it a public IP address that serves as the entry point for incoming traffic. You can associate the public IP address with a friendly DNS name through any DNS vendor.
A public load balancer is regional in scope. If your region includes multiple availability domains, a public load balancer requires either a regional subnet (recommended) or two availability domain-specific (AD-specific) subnets, each in a separate availability domain. With a regional subnet, the Load Balancing service creates a primary load balancer and a standby load balancer, each in a different availability domain, to ensure accessibility even during an availability domain outage. If you create a load balancer in two AD-specific subnets, one subnet hosts the primary load balancer and the other hosts a standby load balancer. If the primary load balancer fails, the public IP address switches to the secondary load balancer. The service treats the two load balancers as equivalent and you cannot specify which one is "primary".
Whether you use regional or AD-specific subnets, each load balancer requires one private IP address from its host subnet. The Load Balancing service supplies a floating public IP address to the primary load balancer.
The floating public IP address does not come from your backend subnets.
If your region includes only one availability domain, the service requires just one subnet, either regional or AD-specific, to host both the primary and standby load balancers. The primary and standby load balancers each require a private IP address from the host subnet, in addition to the assigned floating public IP address. If there is an availability domain outage, the load balancer has no failover.
2) Private Load Balancer
To isolate your load balancer from the internet and simplify your security posture, you can create a private load balancer. The Load Balancing service assigns it a private IP address that serves as the entry point for incoming traffic.
When you create a private load balancer, the service requires only one subnet to host both the primary and standby load balancers. The load balancer can be regional or AD-specific, depending on the scope of the host subnet. The load balancer is accessible only from within the VCN that contains the host subnet, or as further restricted by your security rules.
The assigned floating private IP address is local to the host subnet. The primary and standby load balancers each require an extra private IP address from the host subnet.
If there is an availability domain outage, a private load balancer created in a regional subnet within a multi-AD region provides failover capability. A private load balancer created in an AD-specific subnet, or in a regional subnet within a single availability domain region, has no failover capability in response to an availability domain outage.
NEW QUESTION 73
How is total network throughput allocated to a Virtual Machine (VM) Instance?
- A. When launching a compute instance, customers may select the desired maximum network bandwidth
- B. Each VM is allocated 10 Gbps of network bandwidth regardless of the selected shape
- C. Network bandwidth is variable
- D. Network bandwidth is proportional to the number of OCPUs in the Instance shape
Answer: D
Explanation:
Explanation
A shape is a template that determines the number of CPUs, amount of memory, and other resources that are allocated to an instance.
The network bandwidth is directly proportional to the number of OCPUs in the instance shape!
