An administrator reviews the Health of a virtual machine, as shown in the Exhibit.

Based on the exhibit, which three metrics can be used to determine the virtual machine’s Workload characteristics? (Choose three.)

  1. CPU

  2. Memory

  3. Network IO

  4. Threads

  5. vNUMA Stats

Answer: A,B,C Explanation:

The three most important metrics that are needed to be observed to ensure virtual machine health are CPU, memory and Network I/O because they are directly related to how the virtual machine will perform during peak load hours.

Topic 6, Backup and Recover a vSphere Deployment

Question No: 103 – (Topic 6)

An administrator has created a resource pool named Marketing HTTP with a Memory Limit of 24 GB and a CPU Limit of 10,000 MHz.

The Marketing HTTP resource pool contains three virtual machines:

->Mktg-SQL has a memory reservation of 16 GB.

->Mktg-App has a memory reservation of 6 GB.

->Mktg-Web has a memory reservation of 4 GB.

What would happen if all three virtual machines are powered on?

  1. All three virtual machines can power on, but will have memory contention.

  2. All three virtual machines can power on without memory contention.

  3. Only two of the three virtual machines can power on.

  4. Only one of the virtual machines can power on.

Answer: C Explanation:

Since the limit of 24 GB and CPU limit of 10,000 MH is enforced, only two of the virtual machines can power on simultaneously.

Question No: 104 – (Topic 6)

A vSphere Replication user needs to connect a source site to a target site. What privilege is needed at both sites?

  1. VRM remote.Manage VRM

  2. VRM datastore mapper.Manage

  3. Host.vSphere Replication.Manage replication

  4. Virtual machine.vSphere Replication.Manage replication

Answer: A Explanation:

When connecting sites, users at both sites must have VRM remote.Manage VRM privilege. When you connect sites that are part of the same SSO, you need to select the target site only without providing authentication details, as you are already logged in. After connecting the sites, you can monitor the connectivity state between them at Target Sites tab.

Question No: 105 – (Topic 6)

What is the maximum number of snapshot instances in vSphere Replication that can be configured to recover a virtual machine at a specific point in time?

  1. 16

  2. 24

  3. 48

  4. 72

Answer: B Explanation:

When you configure replication of a virtual machine, you can enable multiple point in time (PIT) instances in the recovery settings in the Configure Replication wizard. vSphere Replication retains a number of snapshot instances of the virtual machine on the target site based on the retention policy that you specify. vSphere Replication supports maximum of 24 snapshot instances. After you recover a virtual machine, you can revert it to a specific snapshot.

Question No: 106 – (Topic 6)

Vmware vSphere Replication protects virtual machines from partial or complete site failures by replicating the virtual machines between which three sites? (Choose three.)

  1. From a source site to a target site.

  2. From within a single site from one cluster to another.

  3. From multiple source sites to a shared remote target site.

  4. From a single source site to multiple remote target sites.

  5. From multiple source sites to multiple remote target sites.

Answer: A,B,C Explanation:

vSphere Replication replaces storage-based replication. It protects virtual machines from partial or complete site failures by replicating the virtual machines from a primary site to a secondary site.

Reference: https://pubs.vmware.com/vsphere- 51/index.jsp?topic=/com.vmware.vsphere.replication_admin.doc/GUID-C987AD18- 7C2D-4FA6-B6E4-6B0DDA915A7A.html

Question No: 107 – (Topic 6)

An administrator subscribes to the vCloud Air Disaster Recovery service. Which replicated objects can be directly monitored and managed?

  1. Virtual machine Snapshots

  2. vApps

  3. Virtual machines

  4. ESXi Hosts

Answer: C Explanation:

You use vSphere Replication at your source site to configure your environment and replicate virtual machines to vCloud Air. You can use vSphere Replication, the vCloud Air portal, or the vCloud Air plug-in to monitor and manage the replicated virtual machines in the cloud.

Question No: 108 – (Topic 6)

Which two capabilities does the vSphere Replication Client Plug-in provide? (Choose two.)

  1. Configure connections between vSphere Replication Sites.

  2. Deploy and register additional vSphere Replication Servers.

  3. Reconfigure the vSphere Replication Server.

  4. Configure an external database for a vSphere Replication Site.

Answer: A,B Explanation:

You use the vSphere Replication client plug-in to perform all vSphere Replication actions.

->Configure connections between vSphere Replication sites.

->View all vCenter Server instances that are registered with the same SSO and status of each vSphere Replication extension.

->Deploy and register additional vSphere Replication servers.

->Configure the replication of individual or multiple virtual machines.

->View incoming and outgoing replications.

->Monitor and manage the status of the replications.

->Recover virtual machines.

Question No: 109 – (Topic 6)

What is the compression algorithm used by vSphere Replication to compress data at the source?

  1. FastLZ

  2. Lz4

  3. Lzr

  4. Lzx

Answer: A Explanation:

vSphere Replication 6.0 utilizes the FastLZ compression library. This provides a nice balance of speed, minimal CPU overhead, and compression efficiency. When using vSphere 6.0 and vSphere Replication 6.0 at both the source and target locations, updates are compressed at the source and stay compressed until they are written to storage at the target. In cases where there is a mixed configuration, packets may be decompressed at some point in the replication path. For example, if a vSphere 6.0 host is connecting to a vSphere Replication 5.8 virtual appliance, packets will not be compressed over the network. Another example: vSphere 6.0 replicating to a vSphere Replication 6.0 virtual appliance, which is writing to vSphere 5.5 host storage – packets are compressed from the source to the vSphere Replication 6.0 -irtual appliance, but are decompressed in the appliance before being written to the vSphere 5.5 storage at the target. Performing this decompression in the vSphere Replication virtual appliance will cause higher vCPU utilization in the appliance. As you can imagine, the most benefit from compression will be realized when running vSphere 6.0 and vSphere Replication 6.0 at both the source and target locations.

Question No: 110 – (Topic 6)

Which three parameters should be considered when calculating the bandwidth for vSphere Replication? (Choose three.)

  1. Data change rate

  2. Traffic rates

  3. Link speed

  4. Application type

  5. Hardware type
