For the full domain and subtopic breakdown, see the Exam Topics section above — that is the outline your TestSimulate practice questions are mapped to.
Question 1
An architect is designing a new vSphere environment to meet the following requirements:
The environment must support 5,000 virtual machines.
The environment will be built initially using 350 hosts.
Which vCenter Server appliance deployment size should the architect specify for the design?
A. Small
B. Medium
C. Large
D. Tiny
Question 2
Which two statements are true about gathering functional business and application requirements? (Choose two.)
A. It focuses on functional requirements with C-level stakeholders
B. It builds stakeholder consensus
C. It leverages a single set of
D. It is a non-iterative process
E. It might require multiple rounds of stakeholder interviews
Question 3
An architect is designing a VMware software-defined data center (SDDC) solution based on the following customer requirements:
The solution must initially support 1,000 virtual machines
The solution must scale to support the concurrent running of up to 5,000 virtual machines The production environment should be delivered across two data centers The solution should have a maximum tolerable downtime (MTD) of four hours The solution should have a monthly service availability target of 99.8% Which two assumptions could the architect make based on the information from the customer to help size the solution? (Choose two.)
A. The average resource utilization of a virtual machine
B. The size (CPU/RAM/storage) of the vSphere hosts
C. The size (CPU/RAM/storage) of the average virtual machine
D. The guest operating system for each virtual machine
E. The number of vSphere hosts in a cluster
Question 4
An architect is designing a solution for an environment with two types of resource profiles that must be virtualized. The first type consists of Tier 1 virtual machines that are disk I/O intensive, but do NOT require high CPU or memory. The second type consists of Tier 2 virtual machines that require a lower CPU and memory allocation and have minimal disk I/O.
Which design recommendation should the architect make for distributing the resource profiles?
A. Run both resource profiles on the same cluster with host hardware that has fast CPU, large amounts of memory, and the fastest storage platform.
B. Run both resource profiles on the same cluster with the same host hardware platform.
C. Separate the two resource profiles into two clusters. The Tier 1 cluster will have fast storage while the Tier 2 cluster will not.
D. Separate the two resource profiles into two clusters. The Tier 2 cluster will have faster CPU and more memory while the Tier 1 cluster will have slower CPU and less memory but more disk space.
Question 5
An architect will be taking over control of a former Linux server fleet and repurposing the hardware into a new vSphere cluster. The current environment is already connected to the network but the hosts do not have any local disks. Since the fleet hardware is uniform, the architect can use a single ESXi image. All hosts within the cluster have the same CPU and memory capacity.
Which ESXi deployment method should the architect use?
A. Stateful vSphere Auto Deploy
B. Manual install of each ESXi host with an image from USB
C. Stateless vSphere Auto Deploy
D. Stateless cached vSphere Auto Deploy
