NEW QUESTION 1
An administrator has configured three vCenter Servers and vRealize Orchestrator within a Platform Services Controller domain, and needs to grant a user privileges that span all environments.
Which statement best describes how the administrator would accomplish this?

• A. Assign a Global Permission to the user.
• B. Assign a vCenter Permission to the user.
• C. Assign vsphere.local membership to the user.
• D. Assign an ESXi Permission to the user.

Answer: A

Explanation: Global permissions are applied to a global root object that spans solutions, for example, both vCenter Server and vCenter Orchestrator. Use global permissions to give a user or group privileges for all objects in all object hierarchies.

NEW QUESTION 15
What is the compression algorithm used by vSphere Replication to compress data at the source?

• A. FastLZ
• B. Lz4
• C. Lzr
• D. 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.

NEW QUESTION 16
An administrator tries to run esxtop to troubleshoot CPU performance issues, but no output is displayed.
How can the issue be resolved?

• A. esxtop is deprecated in vSphere 6.x, resxtop must be used to produce the desired output.
• B. In esxtop, press f and place an asterisk next to each field that should be displayed.
• C. sudo should be run in front of esxtop to give the administrator the proper permissions.
• D. The esxtop command must be run from the /proc directory to produce output.

Answer: B

Explanation: When you press f and place an asterisk next to each field that you want displayed, esxtop will definitely display performance issues, if any.

NEW QUESTION 17
An administrator tries to capture network traffic for a virtual machine, but cannot see the expected traffic in the packet capture tool.
Which step can resolve the problem?

• A. Migrate the virtual machine to a Distributed Virtual Switch.
• B. Enable Promiscuous Mode on the relevant port group.
• C. Modify the default value of MAC Address changes.
• D. Enable Forged Transmits on the virtual machine.

Answer: B

Explanation: Although it is not a good practice to enable promiscuous mode on a distributed virtual switch, you can enable it to solve the problem of traffic stats in packet capture tool.

NEW QUESTION 18
When importing an existing SSL certificate into vSphere Replication Server, which file format is required?

• A. PKCS#12
• B. DER
• C. PEM
• D. PKCS#7
