NEW QUESTION # 40
What are two reasons to create a Kubernetes deployment rather than work with pods directly? (Choose two.)
- A. A deployment ensures that the desired number of pods is running at all times.
- B. A deployment contains imperative instructions on how to re-create a pod if a pod dies unexpectedly.
- C. A deployment is ephemeral and therefore requires less configuration.
- D. A deployment simplifies pod updates and roll-outs.
Answer: A,D
Explanation:
Explanation
A Kubernetes deployment is a resource object in Kubernetes that provides declarative updates to applications. It allows you to describe an application's life cycle, such as which images to use for the app, the number of pods there should be, and the way in which they should be updated1. Two reasons to create a Kubernetes deployment rather than work with pods directly are:
A deployment ensures that the desired number of pods is running at all times1. If a pod crashes, the Deployment will automatically re-create it.
A deployment simplifies pod updates and roll-outs1. It allows you to describe a desired state in its specification and the Deployment controller changes the actual state to the desired state at a controlled rate1. References from Juniper site: Kubernetes Documentation
NEW QUESTION # 41
What is the most privileged protection ring?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
Explanation
In computer science, hierarchical protection domains, often called protection rings, are mechanisms to protect data and functionality from faults and malicious behavior. Rings are arranged in a hierarchy from most privileged (most trusted, usually numbered zero) to least privileged (least trusted, usually with the highest ring number). On most operating systems, Ring 0 is the level with the most privileges and interacts most directly with the physical hardware12. References from Juniper site: Wikipedia, GeeksforGeeks, Notes
NEW QUESTION # 42
You are deploying CN2 using Kubernetes as your orchestrator.
In this scenario, which component contains the vRouter agent?
- A. Ikube-scheduler
- B. kube-manager
- C. worker node
- D. Contrail controller
Answer: C
Explanation:
Explanation
In a CN2 deployment using Kubernetes as the orchestrator, the vRouter agent is contained in the worker node.
The vRouter agent is responsible for managing the forwarding plane on each node in a Contrail cluster. It interacts with the kernel to manage the services and interfaces within the virtual networks.
NEW QUESTION # 43
Which component of a software-defined networking (SDN) controller defines where data packets are forwarded by a network device?
- A. the control plane
- B. the operational plane
- C. the forwarding plane
C the management plane
Answer: C
Explanation:
Explanation
The forwarding plane (also known as the data plane) of a software-defined networking (SDN) controller is responsible for forwarding data packets based on the instructions given by the control plane23. It handles all activities involving data packets sent by the end-user, including forwarding of packets2. References from Juniper site: GeeksforGeeks, SDxCentral
NEW QUESTION # 44
Which two features are provided by CN2? (Choose two.)
- A. application firewall
- B. isolated namespaces
- C. user-defined virtual networks
- D. role-based access control
Answer: B,C
Explanation:
Explanation
According to the CN2 datasheet1, CN2 supports "multiple isolated namespaces for each tenant, allowing for overlapping IP addresses among tenants" and "user-defined virtual networks that can span across clusters, regions, and clouds". Other features of CN2 include cloud-native networking, NetOps-driven automation, edge and remote compute, enhanced observability, and ultra-fast, high performance1.
NEW QUESTION # 45
Which component of an SDN architecture is responsible for configuring and maintaining devices and their state?
- A. the forwarding plane
C the management plane - B. the operational plane
- C. the data plane
Answer: C
Explanation:
Explanation
The management plane in an SDN architecture is responsible for configuring and maintaining devices and their state1. It provides the functions that manage the network, such as configuration, monitoring, and management of network devices. It is the layer of the network that carries administrative traffic, which is used for the network management1.
