Use RDM in virtual mode for virtual disk. Use virtual disks in Independent – Persistent mode. Use a virtual disk larger than 2 TB in size. Use RDM in physical mode for virtual disk.
Correct Answer: BD Section: (none) Explanation Explanation/Reference: Explanation: To exclude a virtual disk from snapshot operations, you have to set it to independent mode: power off the virtual machine delete any existing snapshots before you change the disk mode right-click the virtual machine and select “Edit settings” select the hard disk you want to exclude from snapshots change the mode to “Independent” You have two options when you change the disk mode to independent: Independent Persistent: Changes are written permanently to the disk (same behaviour like conventional disks) Independent Nonpersistent: When you power off, reset or revert the virtual machine to a snapshot all changes to the disk are discarded! Using the nonpersistent mode enables you to restart a virtual machine with a virtual disk in the same state every time. So if you do not want to loose data when changing the power state of the virtual machine, you should take care to use the Independent Persistent mode!

What two in-guest changes can help decrease latency? (Choose two.) A. LRO
https://vceplus.com/ B. TSO C. SR-IOV D. RVRDMA Correct Answer: AB Section: (none) Explanation
Explanation/Reference: Explanation: Using TSO and LRO on physical and virtual machine NICs improves the performance of ESX/ESXi hosts by reducing the CPU overhead for TCP/IP network operations. The host uses more CPU cycles to r un applications. If TSO is enabled on the transmission path, the NIC divides larger data chunks into TCP segments. If TSO is disabled, the CPU performs segmentation for T CP/IP. TSO is referred to as LSO (Large Segment Offload or Large Send Offload) in the latest VMXNET3 driver attributes. LRO reassembles incoming network packets into larger buffers and transfers the resulting larger but fewer packets to the network stack of the host or virtual machine. The CPU has to process fewer packets than when LRO is disabled, which reduces its utilization for networking.

C. D.
All snapshots on the virtual machines will be deleted. The virtual machine will be reverted to its last snapshot. Redundant delta disks will be combined and deleted. A new snapshot with memory state will be created.
Correct Answer: C Section: (none) Explanation Explanation/Reference: Explanation: When initiating a snapshot delete action, the delta disk changes are then written to the base or parent VMDK file and the snapshot is deleted. With vSphere 5, a new option called consolidate was introduced. The purpose of consolidate is if the snapshot deletion process was not successf ul. In the past there were incidents where a user would initiate a snapshot deletion thinking the snapshot got deleted, yet to find out later that that’s not the case. With the consolidation option, when you initiate a snapshot deletion, if the snapshot fails to delete, the VM will then generate a warning letting you k now that a consolidation is required. You would then run the snapshot consolidation option and the snapshot would get committed.

Which action would allow the VM to power on?
A. B. C. D.
Set a 2GB memory reservation on the VM. Mount the virtual disk from the affected VM on to another virtual machine and free up space from within the OS. Enable vSphere HD admission control on the cluster in which the VM resides. Set a 2GB memory limit on the VM.
Correct Answer: A Section: (none) Explanation Explanation/Reference: Explanation: You must reserve swap space for any unreserved virtual machine memory (the difference between the reservation and the configured memory size) on pervirtual machine swap files. Reference: https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.resmgmt.doc/GUID-AC40823A-695B-438A-A8F2-4B7C51A0D014.html QUESTION 47 When using "Cluster resource percentage" for host failover capacity in vSphere HA Admission Control, the total resource requirements are calculated from which two values? (Choose two.) A. B. C. D. E. F.
Total vCPUs assigned to each VM. Average CPU usage on each VM over time. Memory reservations on each VM. Total memory assigned to each VM. Average active memory on each VM over time. CPU reservations on each VM.
Correct Answer: CF Section: (none) Explanation Explanation/Reference: Explanation: vSphere HA uses the actual reservations of the virtual machines. If a virtual machine does not have reservations, meaning that the reservation is 0, a default of 0MB memory and 32MHz CPU is applied. Computing the Current Failover Capacity
The total resource requirements for the powered-on virtual m achines is comprised of two components, CPU and memory. vSphere HA calculates these values. The CPU component by summing the CPU reservations of the powered-on virtual machines. If you have not specified a CPU reservation for a virtual machine, it is assigned a default value of 32MHz (this value can be changed using the das.vmcpuminmhz advanced option.) The memory component by summing the memory reservation (plus memory overhead) of each powered-on virtual machine.

RSA SecurID Smart Card SAML Symantec VIP
Correct Answer: AB Section: (none) Explanation Explanation/Reference: Explanation: Two-Factor Authentication Methods The two-factor authentication methods are often required by government agencies or large enterprises. Smart card authentication Smart card authentication allows access only to users who attach a physical card to the USB drive of the computer that they log in to. An example is Common Access Card (CAC) authentication. The administrator can deploy the PKI so that the smart card certificates are the only client certificates that the CA issues. For such deployments, only smart card certificates are presented to the user. The user selects a certificate, and is prompted for a PIN. Only users who have both the physical card and the PIN that matches the certificate can log in. RSA SecurID Authentication For RSA SecurID authentication, your environment must include a correctly configured RSA Authentication Manager. If the Platform Services Controller is configured to point to the RSA server, and if RSA SecurID Authentication is enabled, users can log in with their user name and token. See the two vSphere Blog posts about RSA SecurID setup for details.

Local Windows OS users and groups Configuration Custom ports FQDN Historical and Performance data
Correct Answer: BD Section: (none) Explanation Explanation/Reference: Explanation: The following list contains features or actions that are currently not supported:
Local Windows OS users and groups are not migrated to the Photon OS of the vCenter Server Appliance 6.5. If you assigned vCenter Server permissions to any Local Windows OS users and groups, remove the permissions assignments before the migration. You can re-create L ocal OS users and groups on t he Photon OS of the vCenter Server Appliance 6.5 after the migration. After the migration, the source vCenter Server is turned off and cannot be turned on to avoid network ID conflicts with the target vCenter Server Appliance. After the source vCenter Server is turned off, all solutions that are installed on the source vCenter Server and that are not migrated become unavailable. Migration of deployments that use custom ports for services other than Auto Deploy, Update Manager, and vSphere ESXi Dump Collector are not supported. The migration process migrates only one network adapter settings to the target vCenter Server Appliance. If the hostname of the source vCenter Server resolves to multiple IP addresses across multiple network adapters, you have the option to select which IP address and network adapter settings t o migrate. You cannot add the rest of the network adapters and settings to the target vCenter Server Appliance. You cannot migrate a vCenter Server instance that uses a DHCP IP address.
