Question #11
Which statement is correct about overlay or underlay networks or fabrics?
- A . Underlay fabrics decouple network services from the overlay infrastructure.
- B . Overlay networks are Layer 3 networks that must use OSPF for routing purposes.
- C . Underlay fabrics enable multitenancy through virtualization.
- D . Overlay networks are virtual networks.
Correct Answer: D
D
Explanation:
Overlay networks are indeed virtual networks. They are logical constructs that stitch together
disparate, dispersed network infrastructure, often referred to as underlay1. Underlay networks refer to the physical network infrastructure, while overlay networks implement network virtualization concepts2.

Question #12
Which two statements are correct about Kubernetes resources? (Choose two.)
- A . A deploymentConfig is a Kubernetes resource.
- B . A daemonSet ensures that a replica of a pod is running on all nodes.
- C . A ClusterIP type service can only be accessed within a Kubernetes cluster.
- D . NodePort service exposes the service externally by using a cloud provider load balancer.
Correct Answer: B, C
B, C
Explanation:
A daemonSet in Kubernetes ensures that a replica of a pod is running on all nodes3. A ClusterIP type service can only be accessed within a Kubernetes cluster3. Reference from Juniper site: Kubernetes Documentation

Question #13
Click the Exhibit button.
Referring to the exhibit, which two statements are correct? (Choose two.)
- A . The c using a custom flavor.
- B . The myvSRX instance is part of a default network.
- C . The myvSRX instance is using a default image.
- D . The myvSRX instance is currently running.
Correct Answer: A, D
A, D
Explanation:
Based on the image description provided, the instance named ‘myvSRX’ appears to be using a custom flavor (not default) and is currently in an ‘ACTIVE’ state, which means it is running.

Question #14
Which two statements are true about VRF instances? (Choose two.)
- A . VRFs share a single routing table.
- B . VRFs do not enable overlapping IP addresses within the same cloud network.
- C . VRFs enable overlapping IP addresses within the same cloud network.
- D . Each VRF has its own routing table.
Correct Answer: C, D
C, D
Explanation:
Virtual Routing and Forwarding (VRF) is a technology that allows multiple instances of a routing table to coexist within the same router at the same time. Because the routing instances are independent, overlapping IP addresses can be used without conflict45. Each VRF has its own routing table4. Reference from Juniper site: Wikipedia, Cisco

Question #15
Which CN2 component provides the network control plane capability?
- A . contrail-k8s-kubemanaqer
- B . contrail-vrouter-nodes
- C . contrail-control
- D . contrail-k8s-controller
Correct Answer: C
C
Explanation:
The network control plane in CN2 represents CN2’s full-featured SDN capability. It communicates with other controllers and uses XMPP to communicate with the distributed data plane components on the worker nodes6. Reference from Juniper site: Juniper Networks

Question #16
What are two characteristics of the OpenShift Assisted Installer? (Choose two.)
- A . It uses one of the control plane nodes as a bootstrap node.
- B . It does not support bare-metal deployments.
- C . It offers REST APIs for the configuration and installation
- D . It provides full feature support and customizations.
Correct Answer: A, C
A, C
Explanation:
The OpenShift Assisted Installer uses one of the control plane nodes as a bootstrap node12. It also offers REST APIs for the configuration and installation12.

Question #17
Which two tools are used to deploy a Kubernetes environment for testing and development purposes? (Choose two.)
- A . oc
- B . OpenStack
- C . minikube
- D . kind
Correct Answer: C, D
C, D
Explanation:
Minikube and kind are two tools that are commonly used to deploy a Kubernetes environment for testing and development purposes3

Question #18
Which two statements are true about virtual networks? (Choose two.)
- A . Virtual networks are available only as part of a cloud orchestration system.
- B . Virtual networks are able to span multiple devices.
- C . Virtual networks are limited to a single device.
- D . Virtual networks are available on common Linux distributions.
Correct Answer: B, D
B, D
Explanation:
Virtual networks are logical networks that are decoupled from the underlying network hardware. This decoupling allows network administrators to manage their networks independently of the physical network topology. As such, virtual networks can span multiple devices, allowing for a high degree of flexibility and scalability. Furthermore, virtual networks are available on common Linux distributions, allowing for easy deployment and management.

Question #19
Which term identifies to which network a virtual machine interface is connected?
- A . Virtual Extensible LAN (VXLAN)
- B . machine access control (MAC)
- C . virtual tunnel endpoint (VTEP)
- D . virtual network ID (VNID)
Correct Answer: D
D
Explanation:
The term that identifies to which network a virtual machine interface is connected is the virtual network ID (VNID). The VNID is a unique identifier assigned to each virtual network. It is used to differentiate between different virtual networks and to ensure that each virtual machine interface is connected to the correct network.

- A . docker cli
- B . containerd
- C . dockerd
- D . docker registry
Correct Answer: C
C
Explanation:
The Docker component that builds, runs, and distributes Docker containers is dockerd. Dockerd is the persistent process that manages containers. Docker uses different binaries for different tasks. For example, it uses the docker binary for CLI commands and dockerd for the daemon process.
