NEW QUESTION # 26
What are two reasons to create a Kubernetes deployment rather than work with pods directly? (Choose two.)
- A. A deployment simplifies pod updates and roll-outs.
- B. A deployment contains imperative instructions on how to re-create a pod if a pod dies unexpectedly.
- C. A deployment ensures that the desired number of pods is running at all times.
- D. A deployment is ephemeral and therefore requires less configuration.
Answer: A,C
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 # 27
Which virtualization technique is used by containers?
- A. full visualization
- B. paravirtualization
- C. hardware-assisted virtualization
- D. OS-level virtualization
Answer: D
Explanation:
Explanation
This technique allows multiple isolated user-space instances to be created by the host operating system. Unlike full virtualization, where the entire system's hardware is emulated, OS-level virtualization shares the host's operating system kernel but isolates the application processes12.
NEW QUESTION # 28

NEW QUESTION # 29
What are the two primary ways used to manage objects by kubectl? (Choose two.)
- A. declarative commands
- B. imperative commands
- C. imperative object commands
- D. declarative object configuration
Answer: B,D
Explanation:
Explanation
The two primary ways used to manage objects by kubectl are imperative commands and declarative object configuration10. Imperative commands operate directly on live objects in a cluster. The user provides operations to the kubectl command as arguments or flags10. Declarative object configuration specifies the operation (create, replace, etc.), optional flags and at least one file name. The file specified must contain a full definition of the object in YAML or JSON format10.
NEW QUESTION # 30
You have started a container in Docker, made configuration changes to it, and stopped the container. You notice the next time that you execute the docker run command, the changes have not persisted.
What is the problem?
- A. The docker exec command needs to be run first to save and exit the running container.
- B. The docker load command must be used to persist the change.
- C. The docker run command starts a new copy of the container, not the existing version.
- D. Docker images need to be recompiled to make any changes.
Answer: C
Explanation:
Explanation
Docker containers are designed to be ephemeral, meaning they run based on their current configuration. When a Docker container is stopped, it does not automatically save changes made during its runtime. When you execute docker run, it starts a new instance of the container, not an existing version with its changes[14-16]. If you want to persist changes between runs, you need to commit changes to a new Docker image or use Docker volumes for data persistence[14-16]. References from Juniper site: Stack Overflow, Docker Docs

Explanation:
Explanation
The service that stores the virtual machine (VM) image in OpenStack is Glance91011. Glance is the image service in OpenStack that allows you to discover, register, retrieve, and store virtual machine images
NEW QUESTION # 32
What are the two characteristics of the Network Functions Virtualization (NFV) framework? (Choose two.)
- A. It implements virtualized tunnel endpoints.
- B. It decouples the network software from the hardware.
- C. It decouples the network control plane from the forwarding plane.
- D. It implements virtualized network functions
Answer: B,D
Explanation:
Explanation
The two characteristics of the Network Functions Virtualization (NFV) framework are that it implements virtualized network functions (VNFs) and that it decouples the network software from the hardware. According to the NFV overview by VMware3, NFV is "designed to deliver the network services needed to support an infrastructure totally independent from hardware by decoupling network functions from proprietary purpose-built hardware appliances" and that "the software that provides these network services are known as virtual network functions (VNFs) and run on generic hardware". Other characteristics that are mentioned in the question are related to Software Defined Networking (SDN), not NFV. SDN separates the network control plane from the forwarding plane and implements virtualized tunnel endpoints.
NEW QUESTION # 33
