Question 1 of 90
Which two of the listed requirements would be classified as performance non-functional requirements? (Choose two.)
Answer

Suggested Answer

The suggested answer is B, D.

Performance non-functional requirements are related to how well a system performs under certain conditions. The requirement for a minimum throughput of 400 MB/s is a performance metric related to data transfer rates, and the requirement for a maximum read latency of 15 ms is a performance metric related to response time. These two requirements are directly concerned with the system's operational efficiency and speed, which classify them as performance non-functional requirements.

Question 2 of 90
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?
Answer

Suggested Answer

The suggested answer is B.

Given that the hosts do not have any local disks, the appropriate deployment method would be Stateless vSphere Auto Deploy. This method does not require any local storage on the hosts as the ESXi image is loaded directly into the host's memory during the boot process. Stateless vSphere Auto Deploy ensures that the hosts are provisioned without needing any local disks, making it the suitable choice for the described setup.

Question 3 of 90
An architect is finalizing the design for a new vCenter Server High Availability deployment.
What is one thing the architect must document in the design?
Answer

Suggested Answer

The suggested answer is B.

In a vCenter Server High Availability (vCenter HA) deployment, it is essential to ensure SSH is configured properly on the vCenter Server's active node. SSH is used for secure communication and key exchange between the active, passive, and witness nodes, which is critical for heartbeat exchanges and data replication. Documenting the SSH configuration ensures that the settings can be validated and troubleshooted as necessary, making it a vital part of the design. Hence, the SSH configuration settings for the vCenter Server's active node must be documented.

Question 4 of 90
An architect is considering placement of virtual machines within an existing VMware software-defined data center (SDDC).
During the discovery phase, the following information is documented:

Cluster One -
✑ Six ESXi hosts
✑ vSphere HA with host failures cluster tolerates = 1
✑ Proactive HA is enabled and set to automated
✑ Fully Automated vSphere DRS
✑ Transparent Page Sharing (TPS) is enabled

Cluster Two -
✑ Eight ESXi hosts
✑ vSphere HA with host failures cluster tolerates = 1
✑ Proactive HA is disabled
✑ Partially Automated vSphere DRS
✑ Transparent Page Sharing (TPS) is disabled

Cluster Three -
✑ Three ESXi hosts
✑ vSphere HA with admission control is disabled
✑ Proactive HA is not supported
✑ Transparent Page Sharing (TPS) is disabled
Virtual Machine Resource Profile 1
✑ Memory sharing techniques should not be used
✑ Virtual machines should be automatically restarted in the event of host failure if resources are available
✑ Automated initial virtual machine placement
Virtual Machine Resource Profile 2
✑ Memory sharing techniques should not be used
✑ Virtual machines should be automatically restarted in the event of host failure regardless of available resources
✑ Automated initial virtual machine placement
Which two recommendations should the architect make for placement of the virtual machines to meet resource profile requirements? (Choose two.)
Answer

Suggested Answer

The suggested answer is C, D.

All virtual machines matching Virtual Machine Resource Profile 1 should be placed on Cluster Two because it disables Transparent Page Sharing (TPS) as required and supports partially automated initial placement due to vSphere DRS being partially automated. All virtual machines matching Virtual Machine Resource Profile 2 should also be placed on Cluster Two because it meets the requirement of disabling TPS and provides automated initial virtual machine placement. Additionally, it can handle automatic restarts of virtual machines in the event of a host failure regardless of available resources, even though Proactive HA is disabled, as it fulfills the primary HA requirement.

Question 5 of 90
An architect is designing a new VMware solution for a customer that has a number of different resource profiles.
The following are the business requirements for the design:
✑ The solution must support virtual machines with the following storage profiles:
- Write-intensive
- Backup
- Write-Once-Read-Many (WORM) archive
✑ The solution must support migration of virtual machine disks between storage profiles.
✑ The WORM archive data must be located at an isolated secure site.
✑ The backup storage array must only be connected to a backup media server.
✑ All data should be recoverable from backup.
Which design decision should the architect make to meet the business requirements?
Answer

Suggested Answer

The suggested answer is C.

The architect should use a different array for each storage profile to meet the business requirements. This approach will ensure that the WORM archive data is located at an isolated secure site, the backup storage array is only connected to a backup media server, and virtual machine disks can be migrated between different storage profiles based on the specified needs.
