質問 # 89
An organization's existing vSphere environments are configured for Enhanced Linked Mode. The DevOps team automates the creation of hardened virtual machine images for various operating systems. Their continuous integration/continuous delivery (CI/CD) pipeline runs a task at the end of a successful build, which uploads the Open Virtualization Format (OV) image to a sandbox content library, deploys a virtual machine from the image, and then destroys these objects after quality checks are complete.
The following requirements have been noted:
- All content libraries and images must be centrally created and managed.
- All images must be capable of being updated.
- All images must be refreshed and available to subscribed libraries within 24 hours.
- All images must provide details of the image contents and versions.
- All images must be capable of being reverted to a previous version.
- All images must be capable of having the hardware and guest operating system customized during deployment.
Which three recommendations should the architect make to design a content library solution that will meet these requirements- (Choose three.)
- A. Create a local content library in the primary vSphere environment and enable publishing.
- B. Add a new subscriber library from each vSphere environment.
- C. Create and publish a new subscription to a new subscriber library for each target vSphere environment.
- D. Edit the Auto Sync Refresh Interval advanced setting for each subscribed library.
- E. Deploy the OVF images to vSphere and clone as a VM template to a local content library.
- F. Deploy the OVF images to vSphere and clone as an OVF template to a local content library.
正解：A、B、E
解説：
As only VM templates can be edited and keep different versions.
質問 # 90
A customer defines a requirement to minimize the vMotion migration time during a maintenance period. The servers being used are equipped with eight 1 GbE network adapters.
Per the defined logical network configuration, there are two network adapters each used for:
- Management traffic
- vMotion traffic
- iSCSI traffic
- Virtual machine traffic
Which design decision should the architect make to meet the customer requirement?
- A. Combine vMotion and Management traffic to make use of four adapters.
- B. Use Network I/O Control to define a reservation for vMotion traffic.
- C. Configure a dedicated TCP/IP stack for vMotion traffic.
- D. Implement Multi-NIC vMotion by adding additional vMotion VMkernels.
正解：D
解説：
We maintain the 2 x 1 GbE network adapters for vMotion and then configure multiple VMkernel interfaces using the same NIC and network. Each time you add a VMkernel adapter and enable it for vMotion, you create a new stream. With more streams, there is greater bandwidth utilization.
質問 # 91
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 vSphere Auto Deploy
- B. Stateful vSphere Auto Deploy
- C. Manual install of each ESXi host with an image from USB
- D. Stateless cached vSphere Auto Deploy
正解：A
解説：
Both Stateless caching and Stateful Auto Deploy options store ESXi configuration or state on the host disk. Since no local disk available, Stateless Auto Deploy is the best option.
質問 # 92
What is the main purpose of analyzing functional requirements?
- A. To ensure the system meets the specified SLA levels.
- B. To determine the system's hardware and infrastructure needs.
- C. To identify the tasks and operations the system must perform.
- D. To optimize the system's performance and responsiveness.
正解：C
