質問 2：
An architect is designing an environment for a retail customer. The design will use a single small vCenter Server Appliance and a cluster of eight ESXi hosts at a remote site. There is a single 10 GbE connected network at the remote site to support all management services. It is not possible to create additional management networks at the remote site. Virtual machine backups at the site will be dependent on the vCenter Server being available.
Which design decision should the architect make to maximize availability for backups?
A. The vCenter Server Appliance will be protected with vSphere Fault Tolerance.
B. The cluster will be configured to use vSphere DRS in fully automated mode.
C. The cluster will be configured with vSphere HA and set to restart virtual machines based on guest operating system heartbeat monitoring.
D. vCenter Server High Availability will be configured.
正解：A

質問 3：
An architect decides to separate virtual desktops and application servers into separate vSphere clusters to meet security and management requirements.
What are two implications of this design decision? (Choose two.)
A. The patching cycles will affect both clusters at the same time.
B. There will be an increase in management overhead.
C. There will be a reduction in performance.
D. There will be additional licensing and cost requirements for both clusters.
E. Identical hardware must be procured for all hosts.
正解：B,C

質問 4：
Refer to the exhibit.
During a requirements gathering workshop, the architect shares the following diagram:

What should the architect recommend for guaranteed throughput for each service?
A. Use the Route Based on IP Hash for ESXi management and VM network Use failover with pNIC1 as Active for backup network Create a link aggregation group (LAG) for vDS_02
B. Use explicit failover order with pNIC0 as Active for ESXi Management and VM Network Use explicit failover order with pNIC1 as Active for backup network Use explicit failover order with pNIC2 as Active for vMotion Use explicit failover order with pNIC3 as Active for replication
C. Create a link aggregation group (LAG) for vDS_01
Use the Route Based on Physical NIC Load for vMotion Use the Route Based on Physical NIC Load for replication
D. Use the Route Based on IP Hash for ESXi management and VM network Use the Route Based on IP Hash for backup network Use the Route Based on the Originating Virtual Port for vMotion Use failover with pNIC3 as Active for replication

質問 5：
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?
A. Create smaller datastores to balance space with Storage DRS
B. Use a larger number of storage profiles (varied disk speeds and RAID levels) to improve performance
C. Create more datastores within each Storage DRS cluster to balance space and performance
D. Create larger datastores to balance space with Storage DRS

質問 6：
Following a recent acquisition, an architect needs to merge IT assets into its current data center. The combined vSphere environment will need to run the newly acquired company's virtual machines.
Network integration work has already been completed and the current environment has capacity to host all virtual machines. The Operations team needs to identify which virtual machines belong to the acquired company and report on their usage.
How should the architect merge the company's assets and virtual machines?
A. Migrate and apply vSphere tags to the acquired company's virtual machines
B. Migrate the acquired company's virtual machines into the existing vSphere environment
C. Lift and shift the acquired assets into the data center
D. Leave the newly acquired company's assets in its current place
正解：A

質問 7：
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. Stateless cached vSphere Auto Deploy
B. Stateless vSphere Auto Deploy
C. Manual install of each ESXi host with an image from USB
D. Stateful vSphere Auto Deploy
正解：B

質問 8：
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
