NEW QUESTION 1
Which two identification sources can a vSphere Auto Deploy rule use to identify target hosts? (Choose two.)

• A. Processor Serial Number
• B. Security Identifier
• C. SMBIOS information
• D. BIOS UUID

Answer: CD

Explanation: Rules can assign image profiles and host profiles to a set of hosts, or specify the location (folder or cluster) of a host on the target vCenter Server system. A rule can identify target hosts by boot MAC address, SMBIOS information, BIOS UUID, Vendor, Model, or fixed DHCP IP address. In most cases, rules apply to multiple hosts. You create rules by using Auto Deploy PowerCLI cmdlets. After you create a rule, you must add it to a rule set. Only two rule sets, the active rule set and the working rule set, are supported. A rule can belong to both sets, the default, or only to the working rule set. After you add a rule to a rule set, you can no longer change the rule. Instead, you copy the rule and replace either items or patterns. By default, Auto Deploy uses the name of the rule for the copy and hides the original rule.

• B. The virtual machines must be using passthrough Raw Disk Mapping (RDMp).
• C. The virtual machines must be using Virtual Machine Disk (VMDK).
• D. The switches in the fabric must be Storage I/O Control aware.

NEW QUESTION 7
The command esxcli network vm list displays four virtual machines connected to the
Production vSwitch. Within the vSphere Web Client, five virtual machines are seen. What explains this behavior?

• A. The fifth virtual machine is currently powered off.
• B. The fifth virtual machine has two vnics.
• C. The fifth virtual machine has an invalid IP address.
• D. The fifth virtual machine has an invalid MAC address.

Answer: A

Explanation: The vSphere client shows all the virtual machines whether they are powered on or off. The fifth virtual machine in this scenario might be powered off. Esxcli network list display virtual machines that are active.

NEW QUESTION 8
An administrator has recently audited the environment and found numerous virtual machines with sensitive data written to the configuration files.
To prevent this in the future, which advanced parameter should be applied to the virtual machines?

• A. isolation.tools.setinfo.disable = true
• B. isolation.tools.setinfo.enable = true
• C. isolation.tools.setinfo.disable = false
• D. isolation.tools.setinfo.enable = false

Answer: A

Explanation: It is configured on a per-VM basis. You can increase the guest operating system variable memory limit if large amounts of custom information are being stored in the configuration file. You can also prevent guests from writing any name-value pairs to the configuration file. To do so, use the following setting, and set it to ‘true’:

NEW QUESTION 9

• C. Upload the offline bundle to a datastore and execute the command esxupdate install –v to apply it manually.
• D. Upload the vib to a datastore and execute the command esxupdate install –v to apply it manually.

Answer: A

Explanation: To patch a host, upload the offline bundle to a datastore and use esxcli software vib install
–d to apply it manually.

NEW QUESTION 17
An administrator observes that virtual machine storage activity on an ESXi 6.x host is negatively affecting virtual machine storage activity on another host that is accessing the same VMFS Datastore.
Which action would mitigate the issue?

• A. Enable Storage IO Control.
• B. Configure Storage DRS.
• C. Enable the Dynamic Queue Depth Throttling option.
• D. Configure the Disk.SchedNumReqOutstanding parameter.

Answer: A

Explanation: SIOC is extremely powerful, it can increase your consolidation ratios on the storage side, allowing more VM's per datastore. Which leads to lower storage costs and less administrative overhead.
So how does it work? At a basic level SIOC is monitoring the end to end latency of a datastore. When there is congestion (the latency is higher than the configured value) SIOC reduces the latency by throttling back VM's who are using excessive I/O. Now you might say, I need that VM to have all of those I/O's, which in many cases is true, you simply need to give the VMDK(s) of that VM a higher share value. SIOC will use the share values assigned to the VM's VMDK's to prioritize access to the datastore.
Just simply turning SIOC on will guarantee each VMDK has equal access to the datastore, shares fine tune that giving you the ability to give VMDK's more or less priority during times of contention.

NEW QUESTION 18
An administrator is using Auto Deploy to create several ESXi 6.x hosts that will be connected to a vSphere Distributed Switch. After the hosts are deployed, the administrator notices that LACP packets are not being sent between them.
Which statement best describes why this issue is occurring?

• A. LACP is not enabled on the vCenter Server.
• B. The LACP support settings do not exist in the host profile.
• C. The LACP installation bundle is not included in the image profile.
• D. LACP has not been configured on the Auto Deploy server.

Answer: B

Explanation: Link Aggregation Control Protocol (LACP) on a vSphere distributed switch allows network devices to negotiate automatic bundling of links by sending LACP packets to a peer. However, there are some limitations when using LACP with a vSphere-distributed switch.
✑ LACP only works with IP Hash load balancing and Link Status Network failover detection.
✑ LACP is not compatible with iSCSI software multipathing.
✑ vSphere only supports one LACP group per distributed switch, and only one LACP group per host.
✑ LACP settings do not exist in host profiles.
✑ LACP between two nested ESXi hosts is not possible.
✑ LACP does not work with port mirroring.
