3V0-21.21 Online Practice Questions and Answers

An architect will be taking over control of a former Linux server fleet and repurposing the hardware into a new vSphere cluster. The current environment is already connected to the network but the hosts do not have any local disks. Since the fleet hardware is uniform, the architect can use a single ESXi image. All hosts within the cluster have the same CPU and memory capacity.

Which ESXi deployment method should the architect use?

A. Stateless cached vSphere Auto Deploy

B. Stateless vSphere Auto Deploy

C. Manual install of each ESXi host with an image from USB

D. Stateful vSphere Auto Deploy

Which design decision must be included in a design to allow for the deployment of a minimum supported configuration of vCenter High Availability (HA)?

A. A new subnet will be provisioned for vCenter HA services

B. A vSphere cluster will consist of more than three nodes

C. The deployed vCenter Server will be Tiny

D. The vCenter HA network will support a latency of less than 50 ms

Refer to the exhibit.

During a requirements gathering workshop, the customer shares the following about their existing ESXi

host virtual networking infrastructure:

The customer confirms that:

Each ESXi host has approximately 200 virtual machines.

They want to maximize the number of concurrent virtual machine migrations.

When placing a host in maintenance mode, it takes a long time to evacuate the virtual machines.

Which two recommendations should the architect make in order to help the customer overcome their

challenge? (Choose two.)

A. Configure the network to use MTU for the VMotion VMKernel to 1,600 bytes

B. Configure the network to use MTU for the VMotion VMKernel to 9,000 bytes

C. Create an additional standard switch with pNIC3 to use for vMotion

D. Use the 3 pNICs and bundle them in a link aggregation group (LAG) configuration

E. Use 10 GbE NICs instead of 1 GbE

An architect is designing a solution based on the following information:

Each ESXi host has a single physical NIC with two 10 Gbps ports.

There is a performance-based service-level agreement (SLA) that guarantees 15 Gbps bandwidth for

production virtual machines at all times.

There is no budget to purchase additional hardware.

The hardware replacement SLA is based on a delivery agreement of two business days.

Which recommendation for the configuration of vSphere High Availability (HA) should the architect include

in the design?

A. Configure vSphere HA Configure % based admission control Configure two isolation addresses Consider an OEM with NIC failure conditions in their Proactive HA plugin

B. Configure vSphere HA Set das.IgnoreRedundantNetWarning to true Consider an OEM with NIC failure conditions in their Proactive HA plugin

C. Configure vSphere HA Configure two existing data stores for heartbeat Consider an OEM with NIC failure conditions in their Proactive HA plugin

D. Configure Proactive HA Automation Level: Automated Remediation: Maintenance mode for all failures Consider an OEM with NIC failure conditions in their Proactive HA plugin

A customer provides the following list of requirements for their vSphere platform:

REQ01 The solution should utilize dual network connections to eliminate single points of failure.

REQ02 The solution should allow logs to be retained for a period of 30 days.

REQ03 All user access to the platform should be recorded for audit purposes.

REQ04 The solution should allow the management of multiple ESXi hosts.

REQ05 The solution should allow users to view the remote console of virtual machines.

Which two of the listed requirements would be classified as non-functional requirements? (Choose two.)

A. The solution should utilize dual network connections to eliminate single points of failure

B. The solution should allow the management of multiple ESXi hosts

C. The solution should allow users to view the remote console of virtual machines

D. All user access to the platform should be recorded for audit purposes

E. The solution should allow logs to be retained for a period of 30 days

An architect is designing a vSphere environment for a customer based on the following information:

The vSphere cluster will have three hosts only due to budget considerations.

A database cluster (node majority) consisting of three virtual machines will be running on the vSphere

cluster.

Which two recommendations can the architect make so that the customer achieves the highest level of

application availability while taking into consideration operational resiliency? (Choose two.)

A. Create VM-VM anti-affinity rules

B. Set das.respectvmvmantiaffinityrules to false

C. Create VM-Host anti-affinity rules

D. Disable vSphere HA during maintenance

E. Set das.ignoreinsufficienthbdatastore to true

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

A customer defines a requirement to minimize the vMotion migration time during a maintenance period. The servers being used are equipped with eight 1 GbE network adapters.

Per the defined logical network configuration, there are two network adapters each used for:

Management traffic vMotion traffic iSCSI traffic Virtual machine traffic

Which design decision should the architect make to meet the customer requirement?

A. Use Network I/O Control to define a reservation for vMotion traffic.

B. Implement Multi-NIC vMotion by adding additional vMotion VMkernels.

C. Configure a dedicated TCP/IP stack for vMotion traffic.

D. Combine vMotion and Management traffic to make use of four adapters.

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

A. The application must be hosted with redundancy levels of N+1 or better.

B. Penetration testing must be executed quarterly with a pass rate of 80% or higher.

C. The application must be capable of handling 200 transactions per second.

D. Administrators must monitor the network traffic of the desired systems.

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?

A. The number of 10 GbE capable ports in the vSAN ReadyNode

B. The use of vSAN ReadyNodes

C. The existing network is 10 GbE capable

D. The use of NVMe drives for cache and capacity
