VMware 3V0-21.23 Practice Test - Questions Answers

To meet the requirement of maximum tolerable downtime (MTD) of one hour per month, the system must ensure that in the event of a host failure, the production applications (virtual machines) are restarted as quickly as possible. Configuring vSphere HA Host Failure Response to Restart VMs ensures that VMs are automatically restarted on available hosts in the cluster if a host failure occurs. This setup minimizes downtime and ensures that the system can recover within the specified MTD of one hour per month.

The company policy requires storage separation of workloads by departments. To meet this requirement, the architect should design the storage architecture to create a dedicated storage volume for each department. This approach allows for logical separation of each department's data, ensuring that workloads from one department are isolated from the others.

Creating new storage volumes for new departments provides scalability. As new departments are added, new volumes can be provisioned without affecting the existing volumes or requiring reconfiguration of the existing department's storage.

The customer's request to use multiple network connections for the ESXi management network is aimed at improving the resilience of the network, which directly supports the availability of the management network. By using multiple network connections (such as NIC teaming), the solution ensures that if one network connection fails, the other connections can maintain connectivity, thus improving the availability of the ESXi management network.

A clustered firewall solution must be placed at the perimeter of the hosting platform, and all ingress and egress network traffic will route via this device:

This is a technical requirement because it specifies how network traffic is to be managed through a specific infrastructure element (the firewall). It outlines how the security device is implemented in the network architecture.

The hosting platform's security information and event management (SIEM) system must be scalable to 20,000 events per second:

This is a technical requirement because it deals with the scalability and performance of the SIEM system. It specifies how the system must handle a large volume of data, which is a technical characteristic of the infrastructure.

The hosting platform's storage must be configured with data-at-rest encryption:

This is also a technical requirement because it defines how the data should be stored securely, which is an implementation detail. It specifies that encryption needs to be applied to stored data, a feature related to storage infrastructure.

This is the business objective that translates to a conceptual model constraint, as it is an external requirement that must be met by the system design, influencing how the architecture should be shaped. Compliance audits often dictate specific standards, security, and operational procedures that must be adhered to, which restricts the design choices in terms of governance and best practices.

This option allows for a centralized repository of VM templates that can be efficiently and repeatedly distributed to multiple locations. By creating a published content library, you enable the new locations to subscribe to this library, ensuring that the templates are synchronized and easily accessible. This approach minimizes manual effort and ensures consistency across all sites.

Creating a separate vSphere cluster for management workloads ensures that these workloads, which are critical for monitoring, managing, and orchestrating the environment, do not compete for resources with compute workloads. This separation enhances the stability and reliability of management functions, even during periods of high resource utilization by compute workloads.

This option aligns with the requirements for growth, scalability, and updating data protection operations. Using vSAN (Virtual SAN) Ready Nodes provides a hyper-converged infrastructure that combines storage and compute resources into a single platform, making it easy to scale both compute and storage without increasing the data center footprint. It also eliminates the need for traditional external storage arrays and allows for better data protection capabilities compared to the agent-based approach.

The solution will create a VM-Host Affinity rule that specifies that workloads must run on hosts in a group.

Creating a VM-Host Affinity rule ensures that specific workloads are restricted to certain hosts, which can be useful to avoid placing critical applications on hosts that may not meet their availability requirements.

The solution will enable vSphere High Availability (HA) with restart priority set to 'Highest' for the application virtual machines.

Enabling vSphere HA ensures that virtual machines are automatically restarted on other hosts in the event of a host failure. Setting the restart priority to 'Highest' for mission-critical VMs ensures that these VMs will have the highest priority for restart if any issues arise.

The solution will enable vSphere Fault Tolerance with vSphere High Availability (HA) virtual machine component failure enabled.

Enabling vSphere Fault Tolerance (FT) ensures that the application VMs are fully protected by creating a live shadow VM that runs in lockstep with the primary VM. In the event of a host failure, the shadow VM will take over instantly, providing continuous availability for the application.

The solution will create a virtual machine DRS group that contains all of the critical application workloads.

Creating a virtual machine DRS (Distributed Resource Scheduler) group for critical workloads ensures that these VMs are placed and migrated to the optimal hosts based on the cluster's resource requirements, improving availability and performance.
