VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 33

A customer requests a review of its current vSphere platform design.
The following information is noted:
✑ There are three different workload profiles for the virtual machines:
- Tier-1 virtual machines operate resource-intensive applications and require dedicated allocations for CPU and RAM.
- Tier-2 virtual machines operate internet-facing applications and require access to externally facing networks.
- Tier-3 virtual machines operate platform management tools such as vCenter Server and have different lifecycle management requirements.
✑ Tier-1, Tier-2 and Tier-3 virtual machines are all hosted on a single large vSphere cluster.
✑ The Chief Information Security Officer (CISO) has raised concerns that hosting externally facing applications alongside management tools does not meet internal compliance standards.
✑ The Operations team has raised concerns about Tier-1 virtual machines negatively impacting the performance of vCenter Server.
✑ The Operations lead has stated that management changes have consistently been rejected by application teams.
As a result of the review, which recommendation should the architect make regarding the design of this platform?

Answer options

Correct answer: D

Explanation

The correct answer, D, is appropriate because using resource pools and shares allows for effective management of resources among different tiers, addressing both performance and compliance concerns. Options A and C suggest physical separation into different switches or clusters, which may not resolve the underlying performance and compliance issues effectively. Option B only addresses Tier-2 virtual machines and overlooks the needs of Tier-1 and Tier-3.
