Which types of networks are available when creating a segment in VMware Cloud on AWS?
Correct Answer:
A
VMware Cloud on AWS GovCloud supports three types of network segments: routed, extended and disconnected.
Routed networks: Routed networks allow you to route traffic between the on-premises data center and the VMware Cloud on AWS environment using a VPN or AWS Direct Connect.
Extended networks: Extended networks allow you to extend the on-premises network to the VMware Cloud on AWS environment using VXLAN. This type of network allows you to extend the on-premises VLANs to the cloud environment, providing a seamless network extension.
Disconnected networks: Disconnected networks are used when there is no direct connectivity between the on-premises data center and the VMware Cloud on AWS environment. This type of network allows you to create isolated networks in the cloud environment for specific use cases, such as disaster recovery or testing.

A cloud administrator is deploying a new software-defined data center (SDDC) in VMware Cloud on AWS. Long-term planning indicates that a minimum of 30 hosts are required.
What is a valid management network CIDR based on the requirements?
Correct Answer:
D
A valid management network CIDR based on the requirements is 10.1.0.0/20, as this provides a range of 4096 IP addresses, which is more than enough for 30 hosts. A /23 CIDR only provides 512 IP addresses, which is not enough for 30 hosts, while a /24 CIDR provides 256 IP addresses and a /16 CIDR provides 65,536 IP addresses, which is more than is needed for the 30 hosts.

A virtual machine running in VMware Cloud on AWS Is experiencing poor CPU performance. What are two steps the cloud administrator can take to troubleshoot this issue? (Choose two.)
Correct Answer:
BE
"It is a good idea to periodically monitor the CPU usage of the host. This can be done through the vSphere Client, using the VMware vRealizeOperations management suite, or by using resxtop. Below we describe how to interpret resxtop"https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/vmc-aws-performance.pdf
Use the VMware vSphere Client to connect to the VMware vCenter which manages the virtual machine and examine its performance statistics. You can use charts, alarms, and events to identify CPU
bottlenecks or contention. Use the Troubleshooting Workbench in VMware vRealize Operations Cloud to look for potential evidence. You can use dashboards, alerts, metrics, logs, and recommendations to diagnose and resolve CPU performance issues.

Which two Tanzu Kubernetes Grid service component must an administrator configure within VMware Cloud to enable to deploy a namespace or their Kubernetes Application developments? (Choose two)
Correct Answer:
CD
Tanzu Kubernetes Grid is a service from VMware Cloud that enables customers to deploy and manage Kubernetes applications in the cloud. In order to deploy a namespace or their Kubernetes Application developments, an administrator must configure a Tanzu Kubernetes Cluster and a Management Cluster.
A Tanzu Kubernetes Cluster is a cluster of nodes that are used to run applications and services. The nodes are connected to the Management Cluster, where administrators can manage and monitor deployments.
The Management Cluster is a cluster of nodes that are used to manage and monitor the Tanzu Kubernetes Cluster nodes. It provides the tools to manage and monitor deployments, as well as to configure and maintain the Tanzu Kubernetes Cluster nodes.
According to VMware's official website, "Tanzu Kubernetes Grid is a service that provides a simplified way to deploy and manage Kubernetes applications in the cloud. It provides a single control plane for managing multiple Kubernetes clusters, allowing customers to easily deploy and manage their applications across multiple clusters and environments." [1]
