Question 38

Due to a recent acquisition, an architect is being asked to identify and design a cloud-based solution that will assist in merging several data centers together without incurring undue operational overhead while adhering to a very strict project timeline. The proposed solution must have the capability to be rapidly recovered in the event of a cloud provider outage. After careful consideration, the architect determines that VMware Cloud on AWS would be an appropriate solution, requiring a total of nine hosts for capacity. Which additional configuration options would satisfy the requirements of this project?

A.

✑ Deploy a VMware Cloud on AWS software-defined data center (SDDC) with a single stand-alone cluster.

✑ Deploy a second stand-alone cluster into the SDDC in a separate region.

✑ Configure VMware Cloud Disaster Recovery to replicate and protect workloads to the second cluster.

B.

✑ Deploy a VMware Cloud on AWS software-defined data center (SDDC) with a single stretched cluster across two separate availability zones.

✑ Configure the cluster to ensure that all virtual machines can be restarted in the second availability zone with a near zero recovery point objective (RPO) in the event of any environment or system failures.

C.

✑ Deploy a VMware Cloud on AWS software-defined data center (SDDC) with a single stretched cluster across two separate regions.

Configure the cluster to ensure that all virtual machines can be restarted in the second region with a near zero recovery point objective (RPO) in the event

of any environment or system failures.

D.

✑ Deploy a VMware Cloud on AWS software-defined data center (SDDC) with a single stand-alone cluster.

✑ Deploy a second SDDC with a stand-alone cluster into a different AWS region.

✑ Configure VMware Cloud Disaster Recovery to replicate and protect workloads to the second cluster.

    Correct Answer:

    Option B is not feasible because a VMware Cloud on AWS stretched cluster requires an even number of hosts, and using a single stretched cluster across two regions is not supported. Option A's suggestion to deploy a second stand-alone cluster in a separate region within the same SDDC is not viable. Option C's idea of a stretched cluster across two distinct regions is technically infeasible. Therefore, the correct answer is D. This involves deploying an SDDC with a single stand-alone cluster, adding another SDDC with a stand-alone cluster in another AWS region, and using VMware Cloud Disaster Recovery to replicate and protect workloads, meeting the project’s requirements for rapid recovery and regional protection.

D. "requiring a total of nine hosts for capacity" - This rules out any stretched cluster option (B and C) https://vmc.techzone.vmware.com/vmc-arch/docs/compute/vmc-aws-stretched-cluster#sec403-sub1 a stretched cluster SDDC is one in which the hosts of the SDDC are evenly split between 2 AZs within an AWS Region (with a hidden “witness” host in a 3rd AZ). Which leaves A and D. A states "Deploy a second stand-alone cluster into the SDDC in a separate region.", you can't do this.

I think the answer is D, you cant deploy nine hosts into a stretched cluster- the number of hosts needs to be even. Also for a cloud provider outage you would want to deploy out of region. Stretched clusters cannot be deployed out of region.

D is the only option. Stretched cluster options are ruled out since the max number of host per stretched cluster is 16 (and customer needs 9 x 2), so B doesn't work, and you can't have stretched clusters with hosts located in different regions.

I would go with D (per nemisis95 info) thanks for the details.

Agree with nemisis95 - D

D is Right Choice

B Look for the key words "without incurring undue operational overhead while adhering to a very strict project timeline". The proposed solution must have the capability to be "rapidly recovered" in the event of a cloud provider outage.

D is the correct answer as explained by nemisis95 and others below.

Answer is B Regional outage is highly unlikely and if protecting against regional outage the answer will be Site Recovery, no VCDR.
