質問 3：
The Chief Operating Officer (COO) at an organization raises concerns that their virtual infrastructure environment is vulnerable. Recently, a security-related issue with a virtual machine caused all management services to become unavailable. No budget is available in the short term for additional platform investment. An architect is asked to review the current environment and make recommendations to mitigate concerns.
A virtualization administrator has provided the following details:
There is a single four node cluster of ESXi servers
There are two, Layer 2, physical network switches connecting resources
The data center network is presented as a single /16 subnet
Given the information provided, which functional requirement should the architect include in the design to mitigate the COOs concerns?
A. The virtual infrastructure environment must connect application virtual machines and management services to new physical network switches
B. The virtual infrastructure environment must connect management services to a vSphere standard switch (VSS)
C. The virtual infrastructure environment must connect application virtual machines and management services to separate distributed virtual switches (DVS)
D. The virtual infrastructure environment must connect application virtual machines and management services to separate VLANs
正解：D

質問 4：
Which design decision must be included in a design to allow for the deployment of a minimum supported configuration of vCenter High Availability (HA)?
A. A vSphere cluster will consist of more than three nodes
B. The deployed vCenter Server will be Tiny
C. A new subnet will be provisioned for vCenter HA services
D. The vCenter HA network will support a latency of less than 50 ms
正解：C

質問 5：
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 the same host hardware platform.
B. 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.
C. Run both resource profiles on the same cluster with host hardware that has fast CPU, large amounts of memory, and the fastest storage platform.
D. Separate the two resource profiles into two clusters. The Tier 1 cluster will have fast storage while the Tier 2 cluster will not.

質問 6：
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?
A. Three
B. Five
C. Two
D. Four
正解：D

質問 7：
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?
A. Request a common shared network with flexible security measures to accommodate different auto deployment options
B. Ask the business to expand the engineering environment to service the virtual environment as well
C. Deploy each ESXi host individually and document it to satisfy security requirements
D. Request an isolated network segment to use and dedicate it to Auto Deploy functions
正解：D

質問 8：
The architect for a large enterprise is tasked with reviewing a proposed design created by a service partner. Which design elements are expected to be detailed within the physical design section of the documentation?
A. A design diagram illustrating the configuration and specific attributes, such as IP addresses
B. An entity relationship diagram describing upstream and downstream dependencies for specific service components
C. A list of requirements, constraints, and risks
D. A solution architecture diagram with the components and data flow
正解：A

質問 9：
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?
A. Separate Tier-1, Tier-2 and Tier-3 virtual machines using resource pools and shares
B. Separate Tier-1, Tier-2 and Tier-3 virtual machines onto dedicated clusters
C. Separate Tier-1, Tier-2 and Tier-3 virtual machines using dedicated distributed virtual switches (DVS)
D. Separate Tier-2 virtual machines onto a dedicated cluster
正解：B
