Question 1:
Which three components should an administrator select when configuring vSphere permissions? (Choose three.)
A. Inventory Object
B. Role
C. User/Group
D. Privilege
E. Password
Correct Answer: ABC
In vSphere, permission consists of a user or group and an assigned role for an inventory object, such as a virtual machine or ESX/ESXi host. Permissions grant users the right to perform the activities specified by the role on the object to which the role is assigned.

Question 2:
Which group in the vsphere.local domain will have administrator privileges for the VMware Certificate Authority (VMCA)?
A. SolutionUsers
B. CAAdmins
C. DCAAdmins
D. SystemConfiguration.Administrators
Correct Answer: B
Members of the CAAdmins group have administrator privileges for VMCA. Adding members to these groups is not usually recommended.

Question 3:
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
Correct Answer: A
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.

Question 4:
An administrator would like to use the VMware Certificate Authority (VMCA) as an Intermediate Certificate Authority (CA). The first two steps performed are:
Replace the Root Certificate
Replace Machine Certificates (Intermediate CA)
Which two steps would need to be performed next? (Choose two.)
A. Replace Solution User Certificates (Intermediate CA)
B. Replace the VMware Directory Service Certificate (Intermediate CA)
C. Replace the VMware Directory Service Certificate
D. Replace Solution User Certificates
Correct Answer: AC
You can replace the VMCA root certificate with a third-party CA-signed certificate that includes VMCA in the certificate chain. Going forward, all certificates that VMCA generates include the full chain. You can replace existing certificates with newly generated certificates. This approach combines the security of third-party CA-signed certificate with the convenience of automated certificate management.

Question 5:
To reduce the attack vectors for a virtual machine, which two settings should an administrator set to false? (Choose two.)
A. ideX:Y.present
B. serial.present
C. ideX:Y.enabled
D. serial.enabled
Correct Answer: AB

Question 6:
Where is a Virtual SAN Fault Domain configured?
A. VMware Virtual SAN Cluster configuration
B. VMware High Availability Cluster configuration
C. Distributed Resource Scheduler configuration
D. Datacenter Advanced Settings configuration
Correct Answer: A
If your Virtual SAN cluster spans across multiple racks or blade server chassis in a data center and you want to make sure that your hosts are protected against rack or chassis failure, you can create fault domains and add one or more hosts to it.
A fault domain consists of one or more Virtual SAN hosts grouped together according to their physical location in the data center. When configured, fault domains enable Virtual SAN to tolerate failures of entire physical rack as well as failures of a single host, capacity device, network link or a network switch dedicated to fault domains. Fault domains cannot be configured for stretched or metro clusters.
The number of failures your cluster can tolerate depends on the number of failures a virtual machine is provisioned to tolerate. For example, when a virtual machine is configured with Number of failures to tolerate=1 and using multiple fault domains, Virtual SAN can tolerate a single failure of any kind and of any component in a fault domain, including the failure of an entire rack. When you configure fault domains on a rack and provision a new virtual machine, Virtual SAN ensures that protection objects, such as replicas and witnesses are placed on different fault domains. If, for example, a virtual machine\’s storage policy is Number of failures to tolerate=n, Virtual SAN requires a minimum of 2*n 1 fault domains in the cluster. When virtual machines are provisioned in a cluster with fault domains using this policy, the copies of the associated virtual machine objects are stored across separate racks.

Question 7:
Refer to the Exhibit.
An administrator wishes to provide Load Balanced I/O for the device shown in the Exhibit. To meet this requirement, which setting should be changed?
A. Storage Array Type Policy = VMW_NMP_RR
B. Path Selection Policy = Round Robin (VMware)
C. Storage Array Type Policy = VMW_SATP_RR
D. Path Selection Policy = MRU (VMware)
Correct Answer: B
In round robin (VMware) the host uses an automatic path selection algorithm rotating through all available paths. This implements load balancing across all the available physical paths.
Load balancing is the process of spreading server I/O requests across all available host paths. The goal is to optimize performance in terms of throughput (I/O per second, megabytes per second, or response times).

Question 8:
An administrator wants to upgrade to vCenter Server 6.x.
The vCenter Server:
Is hosted on a virtual machine server running Microsoft Windows Server 2008 R2, with 8 vCPUs and 16GB RAM.
Will have an embedded Platform Services Controller. Hosts a Large Environment with 1,000 ESXi hosts and 10,000 Virtual Machines.
Why does the vCenter Server not meet the minimum requirements?
A. Windows Server 2008 R2 is not a supported Operating System for vCenter Server.
B. The virtual machine has insufficient resources for the environment size.
C. The environment is too large to be managed by a single vCenter Server.
D. The Platform Services Controller must be changed to an External deployment.
Correct Answer: B
The environment is very big with 1000 ESXi host and 10,000 virtual machines. Therefore, it is not enough and the vCenter server cannot meet these requirements.
Question 9:
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
Correct Answer: A
vSphere Replication can only import and use certificates and private keys from a file in the PKCS#12 format. Sometimes these files have a .pfx extension. Reference: https://pubs.vmware.com/vsphere-51/topic/com.vmware.ICbase/PDF/vsphere- replication-51-admin.pdf
Question 10:
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?
A. All three virtual machines can power on, but will have memory contention.
B. All three virtual machines can power on without memory contention.
C. Only two of the three virtual machines can power on.
D. Only one of the virtual machines can power on.
Correct Answer: C
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 11:
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.
Correct Answer: B
When you press f and place an asterisk next to each field that you want displayed, esxtop will definitely display performance issues, if any.
Question 12:
An ESXi 6.x host in the vCenter Server inventory has disconnected due to an All Paths Down (APD) situation. An administrator has corrected the APD issue on the host, but it still remains disconnected. What action should the administrator take next?
A. Select Restart Management Agents from the DCUI.
B. Execute esxcli system settings advanced set
Correct Answer: A
If the ESXi 6.x in vcenter server inventory has disconnected due to APD, you have to restart management agents from the DCUI.
Question 13:
An administrator is observing slow performance of the vCenter Inventory Service and observes the entries from the wrapper.log file:
Exception in thread “tomcat-exec-2” java.lang.OutOfMemoryError: Java heap spaceException in thread “http-bio-0.0.0.0-10443-Acceptor-0” java.lang.OutOfMemoryError: Java heap space
What should the administrator do to resolve the problem?
A. Increase the memory resources of the vCenter Server.
B. Increase the values using cloudvm-ram-size.
C. Increase the memory resouces of the Platform Services Controller.
D. Increase the wrapper.java.maxmemory value in wrapper.conf.
Correct Answer: A

Question 14:
Refer to the Exhibit.
An administrator has configured a vSphere 6.x DRS cluster as shown in the Exhibit. Based on the exhibit, which statement is true?
A. A virtual machine can be powered on in the Test Resource Pool with a 6 GB Memory Reservation.
B. A virtual machine can be powered on in the Dev Resource Pool with a 8 GB Memory Reservation.
C. A virtual machine from both the Test Resource Pool and the Dev Resource Pool can be powered on with a 4 GB Memory Reservation.
D. No more virtual machines can be powered on due to insufficient resources.
Correct Answer: A
Using 6 GB reservation, a VM can be powered on in the test resource pool. IT has an expandable memory reservation that can help starta VM in the resource pool.
Question 15:
An administrator is configuring resource pools for a vSphere 6.x cluster. The cluster has these characteristics:
Five ESXi 6.x hosts
Six cores per host
70 virtual machines with 1 vCPU each
The administrator configures three resource pools and places the virtual machines into the pools, as follows:
Production pool – High Share value with 40 virtual machines
Infrastructure pool – Medium Share value with 20 virtual machines
Development pool – Low Share value with 10 virtual machines
Given this configuration, what is the expected performance for each group of virtual machines during contention?
A. Virtual machines in the Production pool will perform two times as well as those in the Infrastructure pool.
B. Virtual machines in the Infrastructure pool will perform four times as well as those in the Development pool.
C. Virtual machines in all resource pools will perform equally.
D. Virtual machines in the Development pool will perform two times as well as those in the Infrastructure pool.
Correct Answer: C
