Answer:
2An architect is designing a new vSphere environment to meet the following requirements:
✑ The environment must support 800 virtual machines.
✑ The environment will be built initially using 200 hosts.
Which vCenter Server appliance deployment size should the architect specify for the design?
- Large
- Small
- X-Large
- Medium
Answer: D
3An 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?
- Request an isolated network segment to use and dedicate it to Auto Deploy functions
- Ask the business to expand the engineering environment to service the virtual environment as well
- Request a common shared network with flexible security measures to accommodate different auto deployment options
- Deploy each ESXi host individually and document it to satisfy security requirements
Answer: A
4An 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?
- Three
- Five
- Four
- Two
Answer: C
5An 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.)
- Migration of virtual machines between hosts must be encrypted
- Log information must be verbose to support incident resolution
- Critical events generated within the platform must be logged to an external Syslog service
- Data integrity must be ensured
- A common content library must be maintained across all data centers
Answer:
6An 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?
- Deploy a vCenter server for the management cluster. Deploy a vCenter Server for all remaining clusters. Create a shared SSO domain for each physical site.
- Deploy a vCenter Server for the management cluster. Deploy a vCenter Server for all remaining clusters. Create a shared SSO domain across all physical sites.
- Deploy a vCenter Server for the management cluster with a dedicated SSO domain. Deploy a vCenter Server for all remaining clusters and use a dedicated SSO domain for each physical site.
- Deploy a vCenter Server for the management cluster with a dedicated SSO domain. Deploy a vCenter Server for all remaining clusters and use a dedicated SSO domain into a single physical site.
Answer: C
7An 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?
- Create smaller datastores to balance space with Storage DRS
- Use a larger number of storage profiles (varied disk speeds and RAID levels) to improve performance
- Create larger datastores to balance space with Storage DRS
- Create more datastores within each Storage DRS cluster to balance space and performance
Answer: D
8The Chief Information Security Officer (CISO) for an organization is concerned about the security posture of the operating system images that are used for the provisioning of their Software-as-a-Service (SaaS) applications. The organization is in a growth period. The organization is opening a new data center to launch its next phase of new SaaS-based solutions.
The DevOps team currently creates encrypted virtual machine (VM) templates that are used for various operating systems and adds these to the vSphere inventory. The DevOps team already uses a published content library and has been granted a role with the ability to add and delete library items.
The following requirements have been noted:
✑ Impacts to the DevOps team's operational processes must be kept to a minimum.
✑ The DevOps team must be able to regularly check out a copy of the image for updates and check in a new version of the image.
✑ Images must be synchronized from the primary data center to the new data center.
Which three recommendations should the architect make to design a content library solution that will meet these requirements? (Choose three.)
- Clone virtual machines as VM templates to the published content library
- Create a subscribed library from the published library and synchronize Open Virtualization Format (OVF) templates on-demand
- Create a subscription and publish VM templates to a subscribed content library
- Create a subscribed library from the published library and synchronize Open Virtualization Format (OVF) templates automatically
- Clone virtual machines as Open Virtualization Format (OVF) templates to the published content library
- Update the role for the DevOps team with new privileges
Answer:
9An architect is tasked with planning the design of a new vSphere environment. When commissioned, this environment will be used to migrate an existing set of virtual machines.
An inventory of the existing infrastructure, including configured vCPU, RAM and storage sizes has been provided.
In order for each virtual machine to be migrated, which two data sources with peak and average utilization data are required for sizing? (Choose two.)
- %Ready
- Disk Write latency
- CPU
- Ballooned memory
- IOPS
Answer:
10Which design decision must be included in a design to allow for the deployment of a minimum supported configuration of vCenter High Availability (HA)?
- A new subnet will be provisioned for vCenter HA services
- A vSphere cluster will consist of more than three nodes
- The deployed vCenter Server will be Tiny
- The vCenter HA network will support a latency of less than 50 ms
