質問 # 31
An architect is documenting the design for a new vSphere cluster. The customer provides the following information:
All ESXi hosts will use hardware from the same vendor
All ESXi hosts will be monitored for hardware related issues using the vendor's monitoring tooling The vendor's monitoring tooling provides a plugin for vCenter to allow the hardware status to be visible The customer also informs the architect of the following requirements:
Workloads must be automatically relocated to other hosts in the event that a host hardware is marked as degraded.
Workloads must be automatically restarted on other hosts in the event of a host failure.
What should the architect include in the design to meet these requirements?
- A. vSphere HA will be enabled and set to restart VMs in response to a host failure.VM Monitoring will be enabled with a setting of VM and Application Monitoring.
- B. vSphere HA will be enabled and set to Power off and Restart VMs in response to a host isolation.VM Monitoring will be enabled with a setting of VM Monitoring.
- C. vSphere HA will be enabled and set to Power off and Restart VMs in response to a host isolation.
Proactive HA will be enabled with an Automation Level of Automated. - D. vSphere HA will be enabled and set to restart VMs in response to a host failure.Proactive HA will be enabled with an Automation Level of Automated.
正解：D
解説：
To meet the customer requirements, we need to address the two specific scenarios:
Workloads must be automatically relocated to other hosts in the event that a host hardware is marked as degraded:
This requirement can be fulfilled by Proactive HA. Proactive HA is a feature of vSphere HA that works in conjunction with hardware health monitoring tools, such as the vendor's plugin for vCenter. When the vendor's monitoring tool marks a host as degraded (due to hardware issues), Proactive HA can automatically trigger the migration of workloads to other hosts, based on the Automation Level configuration.
Workloads must be automatically restarted on other hosts in the event of a host failure:
This can be managed using vSphere HA with the setting to restart VMs when a host fails. This ensures that in the event of a host failure, workloads are automatically restarted on available hosts in the cluster.
By enabling Proactive HA with an Automation Level of Automated, the architect ensures that degraded hosts are automatically handled (through workload migration) without manual intervention.
質問 # 32
What is an example of a performance design quality?
- A. The solution must support applications with a maximum tolerable downtime (MTD) of four hours.
- B. The solution must support applications with 1,000 transactions per second (TPS).
- C. The solution must scale to meet spikes in CPU demand.
- D. The solution must provide 40 physical CPU cores and 20 TB of physical memory.
正解：B
質問 # 33
A company has a requirement that all production applications must have a maximum tolerable downtime (MTD) of one hour per month.
Which statement would be included in the conceptual design to support this requirement?
- A. vSphere Fault Tolerance (FT) will not be enabled for the production applications.
- B. vSphere HA Host Failure Response will be set to Restart VMs.
- C. Production applications will run in a dedicated Tier 2 cluster.
- D. Server hardware has been allocated for the production applications.
正解：D
解説：
To meet the requirement of maximum tolerable downtime (MTD) of one hour per month, the system must ensure that in the event of a host failure, the production applications (virtual machines) are restarted as quickly as possible. Configuring vSphere HA Host Failure Response to Restart VMs ensures that VMs are automatically restarted on available hosts in the cluster if a host failure occurs. This setup minimizes downtime and ensures that the system can recover within the specified MTD of one hour per month.
質問 # 34

質問 # 44
An architect is creating the design for a vSphere platform that will be used as the target for a migration from multiple legacy vSphere platforms that are being decommissioned. The customer has provided the following information:
Each legacy platform has its own set of virtual machine templates stored in OVF format.
All of the templates need to be migrated to the new platform.
After migration, the templates should be centralized into a single location.
The templates must be accessible to all clusters in the new platform vCenter instance.
Any new templates added to the central location must be automatically available to all clusters.
Administrators must be able to deploy new virtual machines directly from the template instances.
The customer also confirmed that after the migrations are complete, the new platform will be the only vSphere solution available.
Which design choice should the architect evaluate in the logical design for the storage and management of virtual machine templates?
- A. Use a local content library
- B. Use a dedicated datastore on each vSphere cluster
- C. Use a shared datastore on each vSphere cluster
- D. Use a subscribed content library
正解：D
解説：
A subscribed content library is the best design choice for managing and centralizing virtual machine templates in this scenario. Here's why:
Centralized Management: A subscribed content library allows templates to be stored in a central location and made available to all clusters within the vCenter instance. Any new templates added to the central content library are automatically made available to all subscribed clusters, meeting the requirement for templates to be centrally stored and easily accessible by all clusters.
Automatic Updates: When a new template is added to the central content library, it becomes automatically available to all clusters that subscribe to it, fulfilling the requirement for automatically available new templates.
VM Template Deployment: Administrators can deploy new virtual machines directly from the template instances stored in the content library, which ensures that the deployment process is streamlined and consistent.
質問 # 45
What is the purpose of a virtual data center design?
- A. To create a logical representation of the virtualized data center environment.
- B. To specify the expected levels of system performance and responsiveness.
- C. To determine the hardware and infrastructure requirements for vCenter Server.
- D. To ensure the design meets the required industry regulations and standards.
正解：A
質問 # 46
The DevOps team at an organization is preparing to build and package virtual machine (VM) images that will be added to a content library for a new vSphere environment. Users will deploy virtual machines from the content library.

Which requirement would influence the design decision to use OVF templates in the content library?
- A. Templates must be encrypted.
- B. Templates must be automatically migrated to another ESXi host when a host is inaccessible.
- C. Templates must be able to support license agreement acceptance during deployment.
