NEW QUESTION 6
An administrator enables High Availability (HA) on a Virtual SAN cluster.
There are four vmkernel port groups with the following IP addresses assigned:
✑ Management: 192.168.12.10
✑ vMotion: 192.168.13.10
✑ Virtual SAN: 192.168.14.10
✑ Fault TolerancE. 192.168.15.10
Which IP address will HA use for traffic?

• A. 192.168.12.10
• B. 192.168.13.10
• C. 192.168.14.10
• D. 192.168.15.10

Answer: C

Explanation: Since the IP address of Virtual SAN is 192.168.14.10, HA will use this for traffic because HA uses the original IP of the entity that needs High availability.

NEW QUESTION 7
When attempting to log in with the vSphere Web Client, users have reported the error: Incorrect Username/Password
The administrator has configured the Platform Services Controller Identity Source as:
✑ Type. Active Directory as an LDAP Server
✑ Domain: vmware.com
✑ Alias: VMWARE
✑ Default Domain: Yes
Which two statements would explain why users cannot login to the vSphere Web Client? (Choose two.)

• A. Users are typing the password incorrectly.
• B. Users are in a forest that has 1-way trust.
• C. Users are in a forest that has 2-way trust.
• D. Users are logging into vCenter Server with incorrect permissions.

Answer: AB

Explanation: The possible explanation for this error might be that the users are typing password incorrectly or they are in a forest with has only 1-way trust. You need 2-way trust to get the credentials accepted.

NEW QUESTION 8
Which VMware Single Sign-On component issues Security Assertion Markup Language (SAML) tokens?

• A. VMware Security Token Service
• B. Administration Server
• C. VMware Directory Service
• D. Identity Management Service

Answer: A

Explanation: The security token service issues Security Assertion Markup Language (SAML) tokens. These security tokens pass information about a system user between an identity provider and a web service. This service enables a user who has logged on through vCenter Single Sign-On to use multiple web-service delivered applications without authenticating to each one.

NEW QUESTION 9
An administrator notices that a Windows virtual machine is using 95% CPU in Task Manager.
Which two actions should be taken to resolve this issue? (Choose two.)

• A. Increase the memory reservation of the virtual machine.
• B. Increase the CPU Shares on the resource pool where the virtual machine resides.
• C. Decrease the CPU reservation of the virtual machine.

Answer: BD

Explanation: There are two ways to resolve high CPU usage. First increase CPU shares on resource pool where the VM resides. Secondly, increase CPU limit on the resource pool that serves the concerned VM.

NEW QUESTION 10
Which minor badge items make up the Efficiency badge score for an ESXi host in vCenter Operations Manager?

• A. Workload, Anomalies, Faults
• B. Workload, Stress, Density
• C. Time Remaining, Capacity Remaining
• D. Reclaimable Waste, Density

Answer: D

Explanation: The third major badge that vC Ops reports is Efficiency. We all moved to virtualization in hopes of achieving greater efficiencies but there are varying degrees of efficiency so vC Ops is here to help ensure that you maximize the efficiency of your virtual infrastructure. The efficiency badge score is a weighted combination of Reclaimable Waste and Density.

NEW QUESTION 11
An administrator is assigning a user the Content Library administrator role. The user will only be creating the library for a single vCenter Server.
What is the lowest level of the permission heirarchy that this role can be granted to the user and still allow them to create a Content Library?

• A. Global
• B. Datacenter Folder
• C. Virtual Center
• D. Datacenter

Answer: A

Explanation: To let a user manage a content library and its items, an Administrator can assign the Content Library Administrator role to that user as a global permission. The Content Library Administrator role is a sample role in the vSphere Web Client.
Users who are Administrators can also manage libraries and their contents. If a user is an Administrator at a vCenter Server level, they have sufficient privileges to manage the libraries that belong to this vCenter Server instance, but cannot see the libraries unless they have a Read-Only role as a global permission.

• A. Connections from the ESXi host to all devices on the 192.168.1.0 network and 192.168.2.220 on port 22 are allowed.
• B. Connections coming from IP addresses from the 192.168.1.0 network and 192.168.2.220 on port 22 are allowed.
• C. TCP Connections coming from IP addresses from the 192.168.1.0 network and 192.168.2.220 on port 22 are not allowed.
• D. TCP Connections from the ESXi host to all devices on the 192.168.1.0 network and 192.168.2.220 on port 22 are not allowed.

Answer: B

Explanation: As stated clearly in the IP addresses box, connections coming from 192.168.1.0 and 192.168.2.220 on port 22 are allowed.

NEW QUESTION 13
Refer to the Exhibit.

A vSphere 6.x environment is configured with VMware Virtual Volumes (VVOLs). An administrator accesses the cluster Actions menu, as shown in the Exhibit.
Which option is used to create a VVOL on an existing VVOL container?

• A. Storage
• B. Deploy OVF Template
• C. New vApp
• D. Settings

Answer: A

Explanation: A storage container is the storage that is available physically on your storage array. Now I say physically but this could also be virtually presented storage even on an ESXi host but somewhere somehow it will be back-ended on some physical medium, be it HDD, SSD or hey, maybe even a super fast memory disk. Basically it’s a chunk of physical storage somewhere. Capacity Pools are logical partitions carved out of these to provide a chunk of storage to your VM Admins. Capacity pools may also span multiple storage arrays even across sites. Now you could have a single capacity pool within your storage container or multiple depending on your requirements if you need some sort of logical separation for say separate tenants or separate VM admins needing their own separate chunk of storage but just simply think of it as a chunk of storage presented to your VM admins.
