Question 1

Which requirement would be classified as a functional requirement within the design documentation?

AThe system must perform virtual machine backups through an API.

BVirtual machines must be patched within one month of the patch release date.

CVirtual machines must be restarted within 30 minutes of a host failure.

DThe system must be able to scale to support 500 concurrent virtual machines.

Answer : D

Question 2

A customer has six hosts available in a cluster. When running at full capacity, all virtual machines can be run on two hosts.

How many hosts can the customer place into maintenance mode at the same time while still providing N+2 resiliency to the cluster?

ATwo

BThree

COne

DNone

Answer : A

Question 3

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?

AA design diagram illustrating the configuration and specific attributes, such as IP addresses

BA list of requirements, constraints, and risks

CA solution architecture diagram with the components and data flow

DAn entity relationship diagram describing upstream and downstream dependencies for specific service components

Answer : A

'The physical design is based on the logical design. The physical design includes specific hardware from specific vendors. This design also lists specific configurations for each of the components that are deployed'

Question 4

An architect makes the design decision to install ESXi on embedded and resilient 8 GB SD cards.

What is the impact of this design decision?

AHost profiles must be used for this kind of installation

BScratch partition would need to be created on the external storage

CThe size of the SD cards is too small and the installation will fail

DThe vSphere Auto Deploy feature must be enabled on vCenter Server

Answer : B

https://kb.vmware.com/s/article/2074026 You can store coredumps on the SD boot media, but refrain from configuring the scratch partition here as the logs are write intensive and can cause the SD card to fail faster resulting in re-installation of ESXi

https://blogs.vmware.com/vsphere/2021/09/esxi-7-boot-media-consideration-vmware-technical-guidance.html

A configuration involving the usage of SD card or USB drives as boot media is a minimum of8 GB SD card or USB drive + Locally attached persistent storage device for ESX-OSData partitionmay be used but is also not recommended.Recommended list of locally attached storage devices are listed below.In any case, if an SD or USB device is used for boot media (only SD/USB or SD/USB + local HDD/SSD disk), follow the below instructions to reduce the amount of IO sent to the SD or USB boot media:Enable the ToolsRamDisk option to offload VMTools install/upgrade IO requests on the RAM disk.Ensure the/scratchpartition is configured on persistent storage like a local HDD/SSD or boot from the SAN device.

Question 5

An architect is tasked with designing a greenfield VMware software-defined data center (SDDC) solution that will be used to deliver a private cloud service for a customer.

During the initial meeting with the service owner and business sponsor, the customer has provided the following information to help inform the design:

The solution must support the concurrent running of 1,000 virtual machines

The production environment must be delivered across two geographically dispersed data centers All virtual machines must be capable of running in either data center.

The two data centers are currently connected to each other through a single but diversely routed, high bandwidth and low latency link.

The link between the two data centers is capable of supporting a round-trip time (RTT) of 150 ms The existing server hardware standard document states that all virtual infrastructure hosts must be deployed using vSAN ReadyNodes

The service owner has stated that it is critical to ensure the availability target of 99.9% All virtual machine backups must be completed using the existing backup service

The recovery time objective (RTO) for the service is five minutes

The recovery point objective (RPO) of the service is four hours

Which two elements represent risks to the successful delivery of this solution? (Choose two.)

AThe use of only two data centers

BThe network connectivity between data center sites

CThe use of vSAN ReadyNodes

DThe RTT on the link between the two data centers

EThe use of the existing backup service

Answer : B, E

B) The backup service has sufficient capacity for the new requirements

'All virtual machine backups must be completed using the existing backup service.'

The existing backup service may not have capacity or compatabiltiy for the new SDDC

E) The clusters will have a minimum redundancy of N+1

'The service owner has said that is important to ensure that neither the availability target of 99.5% nor the resource capacity is affected when the operations team completes maintenance activities'

We assume N+1 is sufficient. They may require a higher level of redundancy.

Question 6

During a transformation project kick-off meeting, an architect highlights specific areas on which to focus while developing the new conceptual design.

Which two of the listed statements are business requirements? (Choose two.)

AThe project should use the existing storage devices within the data center

BSites must support a network latency of less than 12 ms round-trip time (RTT)

CThe solution must allow data replication between sites

DThere is no budget specifically assigned for disaster recovery

EThere must not be a single point of failure for the virtual infrastructure

Answer : C, E

Question 7

The 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.)

AClone virtual machines as VM templates to the published content library

BCreate a subscribed library from the published library and synchronize Open Virtualization Format (OVF) templates on-demand

CCreate a subscription and publish VM templates to a subscribed content library

DCreate a subscribed library from the published library and synchronize Open Virtualization Format (OVF) templates automatically

EClone virtual machines as Open Virtualization Format (OVF) templates to the published content library

FUpdate the role for the DevOps team with new privileges

Answer : A, C, F

Content Library in vSphere 7 has a few new privileges that are important to bring up as well as a few existing ones that should be considered. Please refer to the chart below for more details.
