Question #11
An architect is designing a new greenfield environment with 600 ESXi hosts in an automated fashion. The engineering department already has a PXE Boot server,
TFTP server, and DHCP server set up with an NFS mount for their current Linux servers.
The architect must be able to demonstrate and meet a security requirement to have all infrastructure processes separated.
Which recommendation should the architect make for the ESXi host deployment?
TFTP server, and DHCP server set up with an NFS mount for their current Linux servers.
The architect must be able to demonstrate and meet a security requirement to have all infrastructure processes separated.
Which recommendation should the architect make for the ESXi host deployment?
- ARequest an isolated network segment to use and dedicate it to Auto Deploy functions
- BAsk the business to expand the engineering environment to service the virtual environment as well
- CRequest a common shared network with flexible security measures to accommodate different auto deployment options
- DDeploy each ESXi host individually and document it to satisfy security requirements
Correct Answer:
C
C
GPT-4o - Answer
Option A, which involves requesting an isolated network segment dedicated solely to Auto Deploy functions, more effectively meets the stated security requirement of ensuring that all infrastructure processes are separated. This approach minimizes risks associated with deploying ESXi hosts by preventing potential disruptions or vulnerabilities that could arise in a shared network environment. Isolating the network specifically for Auto Deploy functions aligns closely with best practices for maintaining stringent security protocols in a virtualized infrastructure.
Question #12
An architect is designing a new vSphere environment with the following resources:
✑ 600 vCPU
✑ 5,760 GB RAM
Average resource usage is:
✑ 60 vCPU
✑ 1,152 GB RAM
The design must meet the following requirements:
✑ The environment has the ability to burst by 25%.
✑ Each host can schedule 36 vCPUs and has 512 GB RAM.
✑ Management overhead is 20%.
What is the minimum number of hosts required to meet the design requirements?
✑ 600 vCPU
✑ 5,760 GB RAM
Average resource usage is:
✑ 60 vCPU
✑ 1,152 GB RAM
The design must meet the following requirements:
✑ The environment has the ability to burst by 25%.
✑ Each host can schedule 36 vCPUs and has 512 GB RAM.
✑ Management overhead is 20%.
What is the minimum number of hosts required to meet the design requirements?
- AThree
- BFive
- CFour
- DTwo
Correct Answer:
D
D
GPT-4o - Answer
In calculating the minimum number of hosts required to support the given vSphere environment, one must account for both the burst capacity and management overhead. With an initial requirement of 1152 GB of RAM, adding 25% burst and a further 20% for management yields approximately 1728 GB total RAM needed. Considering each host provides 512 GB, it indeed requires at least four hosts to meet these demands adequately. The arithmetic clearly supports this configuration, confirming the necessity for four hosts, rather than two, to satisfy both the burst capability and management overhead efficiently in this scenario. Thus, the earlier indication of "two" hosts being sufficient might be underestimating the requirements.
Question #13
An architect is designing a new vSphere platform to meet a list of requirements from the security team.
Which two requirements would be classified as non-functional requirements? (Choose two.)
Which two requirements would be classified as non-functional requirements? (Choose two.)
- AMigration of virtual machines between hosts must be encrypted
- BLog information must be verbose to support incident resolution
- CCritical events generated within the platform must be logged to an external Syslog service
- DData integrity must be ensured
- EA common content library must be maintained across all data centers
Correct Answer:
BC
BC
GPT-4o - Answer
In the context of designing a vSphere platform, non-functional requirements typically outline how the system operates rather than specific features it must have. Verbose logging (option B) to aid in incident resolution provides a framework for system behavior during operations and therefore, qualifies as a non-functional requirement. Similarly, ensuring that critical events are logged to an external Syslog service (option C) dictates the system's operation mode for compliance and monitoring, also marking it as a non-functional requirement. These selections emphasize system performance and operability, integral to the architecture's design criteria for meeting security protocols effectively.
Question #14
An architect is finalizing the design for a new vSphere platform based on the following information:
✑ All Windows virtual machines will be hosted on a dedicated cluster for licensing purposes.
✑ All Linux virtual machines will be hosted on a dedicated cluster for licensing purposes.
✑ All management virtual machines will be hosted on a dedicated cluster.
✑ A total of ten physical sites will be used to host virtual machines.
✑ In the event of one physical datacenter becoming unavailable, the manageability of the virtual infrastructure in the remaining data centers should not be impacted.
✑ Access to configure the management virtual machines via vCenter Server must be controlled through the management Active Directory domain.
✑ Access to configure the Windows and Linux virtual machines must be controlled through the resource Active Directory domain.
✑ The management and resource Active Directory domains are part of separate Active Directory forests and do not have any trusts between them.
The design will use Active Directory with Integrated Windows Authentication.
How should the architect document the vCenter Server configuration for this design?

Question #15
An architect is reviewing a physical storage design. The customer has specified that storage DRS will be used for ease of operational management for capacity and performance.
Which recommendation should the architect include in the design?
Which recommendation should the architect include in the design?
- ACreate smaller datastores to balance space with Storage DRS
- BUse a larger number of storage profiles (varied disk speeds and RAID levels) to improve performance
- CCreate larger datastores to balance space with Storage DRS
- DCreate more datastores within each Storage DRS cluster to balance space and performance
