QUESTION 61
An administrator finds that vMotion and Storage VMotion operations do not succeed on a virtual machine. The virtual machine has been configured with N_Port ID Virtualization
. The virtual machine has two data RDMs, one using a RAID 5 LUN on using a RAID0+1 LUN. The mapping file for RAID 5 LUN was created on the same datastore as the virtual machine, and the mapping file for the RAID0+1 LUN was placed in a datastore used for production data virtual disks.
Which two statements are true about this configuration? (Choose two)
A. vMotion cannot be used unless boot mapping files are placed on the same datastore.
B. Storage vMotion cannot be used unless both mapping files are placed on the same datastore.
C. Storage vMotion cannot be used with NPIV.
D. vMotion cannot be used with NPIV

QUESTION 62
A series of Auto Deploy ESXi hosts which utilize vDS are unable to boot in prior testing. All of the hosts were able to boot successfully.
Which two conditions might cause this issue? (Choose two)
A. The hosts have experienced a network error.
B. The Auto Deploy server permissions are invalid.
C. vCenter Server is down.
D. The hosts have experienced a local disk error.
Answer: BC
QUESTION 63
What are three true statements about quiescing virtual machine snapshots? (Choose three)
A. VMware Tools is not required for quiescing to be successful.
B. The operation ensures that the snapshot includes a power state.
C. The operations may alter the behavior of applications within the virtual machine.
D. The operation ensures all pending disk I/O operations are written to disk.
E. VMware Tools is required for quiescing to be successful.
Answer: CDE
Explanation:
See:

Quiescing doesn’t allow you to capture a powerstate – the snapshot does that… Quiescing only affect applications in I/O within the VM.
This is why if you snapshot a VM that is running without VMware tools it will snapshot but can also break the VM. For example try snapshotting active directory VM without VMware tools. Eventually it will break it if won’t the first time.

QUESTION 64
Click the exhibit button.
An administrator is applying patches to a batch of ESXi 5.x hosts in an under-allocated HA/DRS cluster. An attempt is made to place the host into maintenance mode, but the progress has stalled at 2%. DRS are configured as shown in the exhibit. Of the four choices below, two would effectively resolve this issue.
Which two steps could be taken to correct the problem? (Choose two.)
A. Manually migrates any running virtual machines to another host
B. Set the cluster to Fully Automated
C. Disable HA Monitoring to allow Maintenance Mode to proceed
D. Set the cluster migration threshold to Aggressive
Answer: BC

- If an ESX host is a part of VMware High Availability (HA) or DR’S cluster, check the Admission Control settings. You may have to disable this option if there are not enough resources to ensure fail over capacity.
- If you want vCenter Server to migrate your running virtual machines automatically to other hosts when placing your host in maintenance mode, DR’S must be enabled in your cluster in the Fully Automated mode.
So my responses are B and C. I think if you change DRS settings through a MM placement it will migrate them… please share your thoughts at: (and try it out in your lab)

QUESTION 65
A virtual machine, VM21, will be migrated between two ESXi 5.x hosts, labeled ESXi01 and ESXi02. Each host has two vSphere Standard Switches (vSS), configured as follows:
1. vSwitch0 has a port group labeled management and a port group labeled vMotion.
2. The management port group contains a vmkernel port tagged for management traffic.
3. The vMotion port group contains a vmkernel port tagged for vMotion traffic.
4. vSwitch0 on ESX01 has an uplink attached to the 10.1.30.0/24 network.
5. vSwitch0 on ESX02 has an uplink connected to the 10.1.30.0/24 network.
6. Each host has a vSwitch 1 with a production port group used by virtual machine traffic.
7. Each vSwitch 1 has an uplink attached to the 10.1.40.0/24
What is true about migrating VH21 to the new host?
A. vMotion would be supported in this configuration
B. Storage vMotion would not be supported in this configuration
C. vMotion would not be supported in this configuration
D. Storage vMotion would be supported it the storage device supports
Answer: A
