NEW QUESTION NO: 15
An object has inherited permissions from two parent objects.
What is true about the permissions on the object?
A. The common permissions between the two are applied and the rest are discarded.
B. The permissions are combined from both parent objects.
C. No permissions are applied from the parent objects.
D. The permission is randomly selected from either of the two parent objects.
Answer: B
Explanation/Reference:
Explanation:
If an object inherits permissions from two parent objects, the permissions on one object are added to the permissions on the other object. For example, if a virtual machine is in a virtual machine folder and also belongs to a resource pool, that virtual machine inherits all permission settings from both the virtual machine folder and the resource pool.

NEW QUESTION NO: 16
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.
Answer: C
Explanation/Reference:
Explanation:
Applying a limit on a vCPU and memory will slow your VM down no matter what because of distribution of resources. Even if there are no other VMs running on that 4 socket quad core host. Powering on all the virtual machine will enables 100% resources to be used by VM hence, only few required VM's will powered
"On" which requires the maximum utilization from the available resources.
Example: When a single (or two) VM has a limit of 5000MHz and 16GB, 6 GB Memory = 22gb utilization will be high and is the only VM running on a host than it will run it full speed as it will be constantly rescheduled for 5000MHz and maximum memory (22-24 GB) Check:

NEW QUESTION NO: 18
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.
Answer: A
Explanation/Reference:
Explanation:
Cause
This issue is occurs if the allocated JVM maximum memory heap is too low for the VMware Inventory service, VMware Profile-Driven Storage service, or VMware VirtualCenter Web Management service.
Several core vCenter Server services use individual configuration files (wrapper.conf) to determine the JVM maximum heap size that each service can use. The VMware Inventory service, VMware Profile- Driven Storage service, and VMware VirtualCenter Web Management service rely on the JVM maximum memory heap configured in their individual wrapper.conf file and play a critical role in the functionality of vCenter Server.
Note: If vCenter Server 5.5 has recently been updated beyond 5.5 U2, see Upgrading VMware vCenter Server 5.5 to 5.5 U2 or later reduces the JVM maximum memory heap size (2114669).
Resolution
This is a known issue affecting vCenter Server 5.x.
To resolve this issue, manually set the inventory size.
To change the JVM maximum memory heap size for a Windows installed vCenter Server 5.x, see, see Configuring Tomcat server settings in VMware vCenter Server 5.1 and 5.5 (2021302).
To manually set the inventory size in vCenter Server Appliance 5.x:
1. Log in to vCenter Server Appliance administration interface (VAMI) URL:
https://vCenter_Server_FQDN\IP:5480
2. Click the Services tab.
3. Change the Inventory Size to Medium or Large, depending on your environment.
Note: The system memory may need to be increased when changing this setting. For more information on environment sizing, see theConfigure Inventory Size for the VMware vCenter Server Appliance section of the Configuring Hosts and vCenter Server guide.
4. Restart the VMware Profile-Driven Storage Service and VMware Inventory Service. For more information, see Stopping, starting, or restarting vCenter Server Appliance services (2054085).

NEW QUESTION NO: 19
Which three Authorization types are valid in vSphere? (Choose three.)
A. Group Membership in vsphere.local
B. Global
C. Forest
D. vCenter Server
E. Group Membership in system-domain
Answer: A,B,D
Explanation/Reference:
Explanation: The primary way of authorizing a user or group in vSphere is the vCenter Server permissions.
Depending on the task you want to perform, you might require other authorization.
vSphere 6.0 and later allows privileged users to give other users permissions to perform tasks in the following ways. These approaches are, for the most part, mutually exclusive; however, you can assign use global permissions to authorize certain users for all solution, and local vCenter Server permissions to authorize other users for individual vCenter Server systems.

# esxcfg-vswitch -l
Run this command for ESXi 5.0:
# esxcli network vswitch standard list

B. Load the new rules using esxcli network firewall refresh.
C. Verify the entries in the XML file and then reboot the ESXi host.
D. Remove the ESXi host from the inventory and add it back.
Answer: B
Explanation/Reference:

Revert the access permissions of the service.xml file to the read-only default by running the command:
# chmod 444 /etc/vmware/firewall/service.xml
Refresh the firewall rules for the changes to take effect by running the command:
# esxcli network firewall refresh

NEW QUESTION NO: 22
Which two statements are correct regarding vSphere certificates? (Choose two.)
A. ESXi host upgrades do not preserve the SSL certificate and reissue one from the VMware Certificate Authority (VMCA).
B. ESXi host upgrades preserve the existing SSL certificate.
C. ESXi hosts have assigned SSL certificates from the VMware Certificate Authority (VMCA) during install.
D. ESXi hosts have self-signed SSL certificates by default.
Answer: B,C
Explanation/Reference:
Explanation:
B-) ESXi hosts that are upgraded from vSphere 5.x to vSphere 6.0 will continue using their Certificate Authority signed certificates if they were replaced in the previous versions. However, ESXi 5.x hosts that were running self-signed certificates and then upgraded to vSphere 6.0 will have their certificates regenerated using VMware-signed.
For more info link:
https://kb.vmware.com/selfservice/microsites/search.do?
language=en_US&cmd=displayKC&externalId=2113926
C-) In vSphere 6.0, VMware tried to address SSL certificates in a different manner. It introduced a new component called the "Platform Services Controller." The Platform Services Controller includes a fully-functional certificate authority, called the VMware Certification Authority (VMCA), that automatically manages the certificates used in vCenter and the ESXi hosts.
There are two steps to complete. First, you need to retrieve the root certificate from vCenter and convert it into something usable. Once you've done that, you need to deploy it as a Trusted Root Certificate. The easiest way to do this with multiple computers is to use Group Policy. Here are the steps to retrieve the certificate:
1.Open your Web browser.
2.Navigate to https://<fqdn of vcenter>
3. In the lower right-hand corner, click the Download Trusted Root CA link.------ for more:
