3V0-21.21 Online Practice Questions and Answers

An architect is finalizing the design for a new vCenter Server High Availability deployment.

What is one thing the architect must document in the design?

A. The load balancing algorithm used by the Management Distributed Virtual Switches (DVS)

B. The SSH configuration settings for the vCenter Server's active node

C. The vCenter Management Network IPv4 addresses for the witness node vCenter Server

A Cloud Service Provider wants to introduce backup as a service for a customer's vSphere-based virtual machines.

The following information is noted: All top-of-rack (ToR) switches are 10 GbE and fully populated The backup traffic must not impact existing services

Which two recommendations should the architect make to help the customer incorporate the service? (Choose two.)

A. Enable and tag traffic on the backup distributed port group

B. Add a new two-port 10 GbE NIC per ESXi host

C. Replace the existing NIC with a two-port 25 GbE NIC per ESXi host

D. Match the Class of Service (CoS) and Differentiated Services Code Point (DSCP) values to the physical network

E. Create a new virtual switch using the 1 GbE uplinks

An architect is designing a new vSphere platform for a customer to meet the following requirements:

The platform must be deployed into five physically separate sites.

The sites are spread across multiple regions.

Some sites require more than one vCenter Server.

The platform must provide an administrator with the ability to access virtual infrastructure components

across all sites from a single management tool instance.

Which single sign-on (SSO) design recommendation will meet these requirements?

A. Use an SSO domain across all vCenter Server instances

B. Use an SSO domain per region

C. Use an SSO domain per vCenter Server instance

D. Use an SSO domain per site

During a requirements gathering workshop to design a physical to virtual migration, the customer provides

the following information:

There is no physical firewall in the data center with no anticipated plans for a future network refresh.

Leveraging the virtual infrastructure to mitigate the lack of network security must be addressed in the

design.

All physical servers to be migrated exist on the same VLAN.

Which recommendation should the architect make to address the customer requirement with regard to

virtual networking?

A. Split the virtual machines into several VLANs Use tag actions

B. Create port groups with different names and same VLAN IDs Enable traffic shaping for ingress and egress traffic

C. Enable traffic filtering and marking Use allow or drop actions

D. Disable traffic filtering and marking Use tag actions

A customer has a database cluster with 40/60 read/write ratio and a high IOPs requirement with no contention on an all-flash vSAN cluster.

Which two storage settings should be configured for best performance? (Choose two.)

A. IOPs limits enabled

B. RAID 1

C. Deduplication and Compression disabled

D. RAID 5/6

E. Deduplication and Compression enabled

Which two statements are true about gathering functional business and application requirements? (Choose two.)

A. It focuses on functional requirements with C-level stakeholders

B. It leverages a single set of questions for all stakeholders

C. It might require multiple rounds of stakeholder interviews

D. It builds stakeholder consensus

E. It is a non-iterative process

An architect is designing an environment for a retail customer. The design will use a single small vCenter Server Appliance and a cluster of eight ESXi hosts at a remote site. There is a single 10 GbE connected network at the remote site to support all management services. It is not possible to create additional management networks at the remote site. Virtual machine backups at the site will be dependent on the vCenter Server being available.

Which design decision should the architect make to maximize availability for backups?

A. vCenter Server High Availability will be configured.

B. The vCenter Server Appliance will be protected with vSphere Fault Tolerance.

C. The cluster will be configured to use vSphere DRS in fully automated mode.

D. The cluster will be configured with vSphere HA and set to restart virtual machines based on guest operating system heartbeat monitoring.

As part of a requirements gathering workshop, the customer provides the following requirements for the

design of a new greenfield virtual infrastructure:

Some applications have a latency that must be less than 5 minutes.

The solution must be able to support a workload growth rate of 10% per year.

Which requirement classification is being gathered for the design documentation?

A. Performance

B. Manageability

C. Recoverability

D. Availability

Following a recent acquisition, the architect learns that both companies use vSphere on-premise and will need to combine the data centers into one. The acquired company's licenses will not be renewed for cost-savings related to the acquisition. All consumed vSphere licenses must have active support to support lineof-business operations. The merged environment must maintain 25% spare capacity. The architect has a small budget remaining unallocated for hardware.

The architect has calculated that the current vSphere environment can absorb the acquired company's virtual machines but the cluster will run at 90% memory utilization and at 50% CPU utilization.

Which design decision can the architect make to incorporate the new company's virtual machines into the combined vSphere environment?

A. Migrate the acquired company's virtual machines into the vSphere environment as it will currently fit.

B. Use the current budget to add memory to the cluster to increase each ESXi host's capacity and add the new virtual machines.

C. Purchase extra hosts to add to the cluster in anticipation of adding the acquired company's virtual machines.

D. Purchase new licenses for some of the acquired company's ESXi hosts and add them to the cluster to hold the acquired company's virtual machines.

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.)

A. Use Route Based on Physical NIC Load.

B. Use Network I/O Control with Shares.

C. Use Network I/O Control with Reservation.

D. Use Link Aggregation Control Protocol (LACP).

E. Use Network I/O Control with Limits.
