Question 1

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



Answer : D


Question 2

A new real-time financial service application is being developed by the engineering team at a financial firm and will be released as a public Software-as-a-Service (SaaS) offering. The solutions architect has designed and deployed a new vSphere environment and the supporting network infrastructure for hosting all public services. ESXi hosts are configured to use Precision Time Proalhazi@1tocol (PTP) and a local stratum-1 network time server.

Application provisioning and scaling will be managed by VMware vRealize Automation and can be run on Microsoft Windows or multiple distributions of Linux.

Which three recommendations should the architect include in the design to ensure that the service maintain timekeeping within an accuracy of one second? (Choose three.)



Answer : B, D, E

Question 3

During a requirements gathering workshop, the customer provides the following information:

Each host has 2 10 GbE NIC

EtherChannel is not currently configured

No changes can be made to the physical network

Network throughput must be prioritized for defined critical services

Which two recommendations should the architect make with regard to virtual networking? (Choose two.)



Answer : A, B


Question 4

A VMware Service Provider is tasked with delivering a solution for continuous availability for a subset of Tier 1 virtual machines (VMs) and vApps running in their vSAN environment. The VMs make up a mission-critical application and there can be no data loss in the event of an outage at their primary data center. In the event of a regional outage, they have established a 10-minute recovery point objective (RPO). Failover/failback to the third site must be automated.

They have the following in place:

Two local data centers (primary and secondary) connected with 100 Gb dedicated fiber

2ms round-trip time (RTT) latency between the sites

A third data center located on another power grid

70ms latency between the primary and secondary data centers

Matching storage arrays at all locations

Which two solutions could be used to meet the requirements? (Choose two.)



Answer : A, C

- a latency of less than or equal to 100 milliseconds is preferred.

Witness to Site -- less than 100msec; 200msec is acceptable https://www.delltechnologies.com/asset/en-us/products/converged-infrastructure/technical-support/vxrail-stretched-cluster-planning-guide-for-7-0.pdf - a latency of less than or equal to 100 milliseconds is preferred.


Question 5

An architect is tasked with designing a new VMware software-defined data center (SDDC) using VMware vSAN. The architect uses a storage assessment tool to determine the storage requirements for the new vSAN cluster. The new SDDC is going to be deployed into the existing data center and must be connected to a shared core network switch.

The architect decides to use vSAN ReadyNodes with the following configuration:

Two disk groups with:

Write Intensive NVMe 800 GB drive for cache

Four 3.84 TB Mixed Use NVMe for capacity

Four 10 GbE ports

Which element represents a risk that should be included in this design?



Answer : C


Question 6

An architect is designing a VMware solution for a customer to meet the following requirements:

The solution must use investments in existing storage array that supports both block and file storage.

The solution must support the ability to migrate workloads between hosts within a cluster.

The solution must support resource management priorities.

The solution must support the ability to connect virtual machines directly to LUNs.

The solution should use existing 32G fabric infrastructure.

There is no budget for additional physical hardware.

Which design decision should the architect make to meet these requirements?



Answer : A

Support the ability to connect virtual machines directly to LUNs, seems to have VMs with RDM, FC supports this type of deployment and so A makes sense. Extra transceivers for FCoE need to be installed, as per budged limited no space to invest on those


Question 7

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



Answer : D

Functional requirements describe what a system or solution must do. The requirements include the following categories:

* Business rules: For example, the architecture must support both the primary and secondary data centers.

* Administrative functions: For example, network and security administrators must monitor the network traffic of the desired systems.
