VMware vSphere 8.x Advanced Design 3V0-21.23 Exam Practice Test

Answer : D

Network I/O Control (NIOC) is a key feature available with distributed virtual switches (vDS) that allows administrators to prioritize and allocate bandwidth to specific network traffic types. It ensures that business-critical applications receive the necessary bandwidth and maintain a consistent quality of service (QoS). This solution meets the requirement to ensure optimal network bandwidth allocation and service consistency.

Answer : B

The Enterprise License Agreement (ELA) is a business factor that will impact the design because it defines the licensing structure, which directly influences the solution's cost, scalability, and use of VMware products. The ELA could provide benefits such as discounted licensing costs, a predefined set of VMware products, or specific terms and conditions that must be adhered to in the design.

Answer : B, D

The storage may not have capacity to accommodate 20% year-over-year virtual machine growth.

This is a risk because, while the assumption is that the storage hardware has sufficient capacity, there is a possibility that the hardware may not be able to support future growth, especially if the customer's workload grows faster than expected. Documenting this risk ensures that the design considers potential capacity constraints.

The customer may not have an existing licensing subscription that covers features the architect intends to use.

This is a risk because although the assumption is that the customer will provide licensing, there may be discrepancies between the features required for the design and the customer's existing licensing. This risk ensures that the architect verifies that the customer's licensing aligns with the solution requirements.

Answer : A, C

VMware Validated Solutions offer prescriptive, step-by-step runbooks that help guide users through the deployment process. These runbooks ensure that the implementation follows VMware's recommended practices, reducing complexity and ensuring consistency across deployments.

VMware Validated Solutions are designed based on VMware's best practices, ensuring that the deployed solution is optimized for performance, security, and scalability. This helps organizations achieve a reliable and efficient infrastructure aligned with VMware's recommended guidelines.

Answer : A

This is a business factor because it directly relates to the financial goals and constraints of the customer. Keeping IT infrastructure costs at a minimum will impact the design by influencing decisions regarding hardware selection, deployment scale, and resource allocation, among other factors.

Answer : D

VMware NSX: NSX provides a centralized platform for network virtualization and security, which aligns with the requirement for enforcing virtual network security policies. It can manage network segmentation, security policies, and micro-segmentation across the entire environment, including both virtual machines and containerized applications.

Distributed Firewalls: NSX's distributed firewall allows for micro-segmentation, meaning that network access is denied between workloads by default, and access controls can be applied based on security policies. This meets the requirement of denying network access by default.

Port Mirroring: Port mirroring in NSX can integrate with the security team's network monitoring solutions. It enables the security team to capture traffic for monitoring and analysis, addressing the requirement for network monitoring support.

Answer : C

The goal here is to ensure that, in the event of a host failure, the workloads are restarted in the correct order based on their dependencies:

Workload 3 (Identity Broker) is required by both Application A and Application B as a dependency. It needs to be set to High Restart Priority, ensuring that it is restarted before the other dependent workloads.

Workload 4 (Reporting Tool) is required by Application B and Application C, so it should be set to High Restart Priority to ensure it is available before the other dependent workloads (like Workload 5).

Workload 5 (Management Tool) is required by Application C and should have a Medium Restart Priority, meaning it will be restarted after Workload 4.

Workloads 1 and 2 (Self-Service Portal and Database) have Low Restart Priority because they are dependent on Workload 3 (and Workload 4), but they do not have further critical dependencies after Workload 3, so they should be restarted last in the event of a failure.

This setup ensures that all applications can be recovered properly in the event of a host failure, with each workload restarting in the correct order to maintain the application dependencies.
