An architect is designing storage for a new vSphere environment to meet the following requirements:

    Asynchronous replication is required between two sites.

    The impact on the storage layer should not impact the performance of the compute layer.

    Each application tier will require different replication attributes.

    Virtual machine live migration across compute and storage must be supported.

    Virtual machine aware back up will be leveraged.

    Operational management overhead should be minimized.

    Operational automation should be supported.

Which storage design recommendations would meet the requirements?

A.

Two new Fibre Channel storage arrays will be deployed, one at either site.

Each application tier will be initially provisioned a new LUN. Data replication will be offloaded to the new arrays.

B.

Two new vSphere clusters enabled with vSAN will be deployed, one at either site. vSAN will be used to provide policy-based management for each application tier.

vSphere Replication will be used to replicate the virtual machine data in an asynchronous configuration.

C.

Two new ISCSI storage arrays will be deployed, one at either site.

Each application tier will be initially provisioned a new LUN. Data replication will be offloaded to the new arrays.

D.

Two new storage arrays will be deployed, one at either site.

vSphere Volumes (vVOLs) will be used to provide policy-based management for each application tier. Data replication will be offloaded to the new arrays.

An architect decides to separate virtual desktops and application servers into separate vSphere clusters to meet security and management requirements.

What are two implications of this design decision? (Choose two.)

A.

There will be an increase in management overhead.

B.

Identical hardware must be procured for all hosts.

C.

There will be a reduction in performance.

D.

The patching cycles will affect both clusters at the same time.

E.

There will be additional licensing and cost requirements for both clusters.

An architect is designing a new vSphere environment to meet the following requirements:

    The environment must support 5,000 virtual machines.

    The environment will be built initially using 350 hosts.

Which vCenter Server appliance deployment size should the architect specify for the design?

A.

Large

B.

Small

C.

Tiny

D.

Medium

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

A.

The vSphere platform must be able to provide a recovery time objective of 30 minutes

B.

The vSphere platform must be able to provide a minimum throughput of 400 MB/s

C.

The vSphere platform must be able to provide N+1 redundancy

D.

The vSphere platform must be able to provide a maximum read latency of 15 ms

E.

The vSphere platform must be able to provide a service-level agreement (SLA) of 99,9%

As part of a new hybrid cloud initiative for a large financial company, the customer technical team is presenting an overview of the current state of the infrastructure and their vision for a new solution.

The project team captures notes during the presentation and adds them to the discovery documentation. Which of the listed statements is a design constraint?

A.

The applications are created in-house with in-guest recovery protection

B.

The maximum tolerable data loss is 10 minutes

C.

The two data center locations have a network latency of 8 ms round-trip time (RTT)

D.

The existing storage is out of maintenance

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
