NEW QUESTION # 22
What is the most privileged protection ring?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
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 # 23
Which two statements are correct about OpenShift monitoring? (Choose two.)
- A. OpenShifis able to configure customized alerts.
- B. OpenShifhas its own monitoring framework.
- C. OpenShifis not able to configure customized alerts.
- D. OpenShifmonitoring is not compatible with Grafana.
Answer: A,B
Explanation:
Explanation
OpenShift includes a preconfigured, preinstalled, and self-updating monitoring stack that provides monitoring for core platform components4. You also have the option to enable monitoring for user-defined projects4. This means OpenShift has its own monitoring framework (B) and is able to configure customized alerts (D).

NEW QUESTION # 24
Which two statements are true about VRF instances? (Choose two.)
- A. VRFs do not enable overlapping IP addresses within the same cloud network.
- B. Each VRF has its own routing table.
- C. VRFs share a single routing table.
- D. VRFs enable overlapping IP addresses within the same cloud network.
Answer: B,D
Explanation:
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. References from Juniper site: Wikipedia, Cisco
NEW QUESTION # 25
Which component of Kubernetes runs on all nodes and ensures that the containers are running in a pod?
- A. container runtime
- B. kubelel
- C. kube-proxy
- D. kube controller
Answer: B
Explanation:
Explanation
The kubelet is a component of Kubernetes that runs on all nodes in the cluster and ensures that containers are running in a pod910. It takes a set of PodSpecs that are provided through various mechanisms and ensures that the containers described in those PodSpecs are running and healthy
NEW QUESTION # 26
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 limited to a single device.
- C. Virtual networks are able to span multiple devices.
- D. Virtual networks are available on common Linux distributions.
Answer: C,D
Explanation:
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.
NEW QUESTION # 27
Which virtualization technique is used by containers?
- A. hardware-assisted virtualization
- B. full visualization
- C. OS-level virtualization
- D. paravirtualization
Answer: C
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
In OpenShift, which node type is used to host your application containers?
- A. miner node
- B. worker node
- C. control plane node
- D. full node
Answer: B
Explanation:
Explanation
In OpenShift, the worker node is used to host your application containers1. Worker nodes are where all your coding adventures happen, and they can be virtual or physical1. References from Juniper site: IBM Developer
NEW QUESTION # 29
Your organization has legacy virtual machine workloads that need to be managed within a Kubernetes deployment.
Which Kubernetes add-on would be used to satisfy this requirement?
- A. Romana
- B. KubeVirt
- C. Canal
- D. ADOT
Answer: B
Explanation:
Explanation
KubeVirt is a Kubernetes add-on that allows you to run and manage legacy virtual machine workloads alongside container workloads within a Kubernetes deployment. According to the KubeVirt website, KubeVirt is "a virtual machine management add-on for Kubernetes" that "aims to provide a common ground for virtualization solutions on top of Kubernetes". Other Kubernetes add-ons that are mentioned in the question are Canal, which is a network policy provider that combines Flannel and Calico; ADOT, which is a distribution of the OpenTelemetry Collector that supports tracing and metrics collection for AWS services; and Romana, which is a network and security automation solution that supports multiple network topologies and policies.
NEW QUESTION # 30
Which two statements are correct about an overlay network? (Choose two.)
- A. The overlay network provides physical connectivity between devices.
- B. The overlay network is the virtual network used to connect multiple virtual machines (VMs).
- C. The overlay network is built using encapsulation tunnels.
- D. The overlay network can only be built using a Layer 3 underlay network.
Answer: B,C
Explanation:
Explanation
An overlay network is a virtual network that is built on top of another network. Nodes in the overlay network are connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network45. For example, distributed systems such as peer-to-peer networks and client-server applications often overlay their own network connections over the physical network connections provided by the Internet
NEW QUESTION # 31
Which two Linux commands would you use to show the amount of RAM in your system? (Choose two.)
- A. cat /proc/cpuinfo
- B. cat /proc/meminto
- C. free -h
- D. df -h
Answer: B,C
Explanation:
Explanation
he free -h command in Linux displays the total amount of free and used physical and swap memory in the system, as well as the buffers used by the kernel89. The cat /proc/meminfo command displays real-time information about the system's memory usage as well as the buffers and shared memory used by the kernel1
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
What are two Kubernetes objects? (Choose two.)
- A. pod
- B. namespace
- C. cluster
- D. service
Answer: A,D
Explanation:
Explanation
In Kubernetes, a Pod is the smallest and simplest unit in the Kubernetes object model that you create or deploy23. A Pod represents processes running on your cluster23. A Service in Kubernetes is an abstraction which defines a logical set of Pods and a policy by which to access them23.
