Questions # 21:

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?

Options:

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.

Questions # 22:

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.)

Options:

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

Questions # 23:

A architect is designing a new VMware software-designed data center (SDDC) using vSphere 7 to meet the following requirements:

    The SDDC must be deployed at two locations: primary and secondary.

    vSphere Replication must be used to replicate virtual machines between the two locations.

    Site Recovery Manager must be used to orchestrate disaster recovery (DR) activities.

    One single-sign on (SSO) domain must be used to authenticate access at both locations.

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

Options:

A.

A vCenter Server Appliance will be deployed to each site. Unique SSO domains will be created per site.


B.

A vCenter Server will be installed on Windows virtual machines deployed to both sites.


C.

A vCenter Server Appliance will be deployed to each site.


D.

A vCenter Server Appliance will be deployed to the primary site only.

Questions # 24:

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

    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 IPv4 based network infrastructure.

    There is no budget for additional physical hardware.

Which two design decisions could the architect make to meet these requirements? (Choose two.)

Options:

A.

The ESXi hosts will leverage Fibre Channel (FC)


B.

The ESXi hosts will leverage NFS 3


C.

The ESXi hosts will leverage Fibre Channel over Ethernet (FCoE)


D.

The ESXi hosts will leverage iSCSI


E.

The ESXi hosts will leverage NFS 4.1

Questions # 25:

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?

Options:

A.

Performance


B.

Manageability


C.

Recoverability


D.

Availability

Questions # 26:

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?

Options:

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
