Question #1
Your company has a Web app hosted in Kubernetes with a fluctuating number of pods.
In this scenario, which Kubernetes service type would provide equal access to all nodes using a single URL?
- A . ExternalName
- B . NodePort
- C . LoadBalancer
- D . ClusterIP
Correct Answer: C
C
Explanation:
The LoadBalancer service type in Kubernetes exposes the service externally using a cloud provider’s load balancer67. NodePort and ClusterIP services, to which the external load balancer routes, are automatically created

Question #2
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 #3
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 #4
Which virtualization technique is used by containers?
- A . OS-level virtualization
- B . full visualization
- C . hardware-assisted virtualization
- D . paravirtualization
Correct Answer: A
A
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.

Question #5
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 #6
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.
