NEW QUESTION 9
In vSphere 6.5, a virtual machine is thinly-provisioned on a VMFS6 datastore. The administrator deleted a large file within the guest OS. The freed blocks in the datastore are no longer needed by the VM. Which feature in vSphere 6.5 allows the backing storage to automatically reclaim the freed blocks?
A. ATS
B. Defrag
C. UNMAP
D. Auto Reclaim
Answer: C
Explanation:
VAAI UNMAP was introduced in vSphere 5.0 to allow the ESXi host to inform the backing storage that files or VMs had be moved or deleted from a Thin Provisioned VMFS datastore. This allowed the backing storage to reclaim the freed blocks. There was no way of doing this previously, resulting in many customers with a considerable amount of stranded space on their Thin Provisioned VMFS datastores.
NEW QUESTION 10
A new virtual machine cannot reach its default gateway.
– The vSphere administrator checks that the virtual machine’s vmnic is connected to the correct portgroup, and that the portgroup is on the correct virtual switch.
– This is the only virtual machine on this portgroup.

– The Distributed Switch has only one uplink.
Which could be the cause of this issue?
A. Block All Ports has been selected on the Distributed Switch.
B. The wrong VLAN ID has been added to the portgroup.
C. The VLAN has not been configured in virtual machine hardware settings.
D. The physical adapter is down.
Answer: D

Going with D
Sorry I meant B
Would go for D.
ERSPAN encapsulates the packets and allows it to transfer over layer 3. so this is used when you want to remotely monitor a port. i think this also needs to be configured on the physical switch…
Confirmed, the right answer is D as it is stated here https://blogs.vmware.com/vsphere/2011/08/vsphere-5-new-networking-features-port-mirroring.html
“choose a VLAN to encapsulate these mirrored packets by selecting the Encapsulations VLAN box.”
Got some further informations on this site since I wasn’t sure about my previous post: http://www.routereflector.com/2014/07/port-mirroring-on-vmware-vswitchdvswitch-dvmirror/
It seems that the feature is ERSPAN and the VLAN ID is simply used to move the generated mirrored traffic packets over the network.
I would choose B then.
Confirmed B (just finished the exam with flying colors)
In regards of answer D, VLAN is a necessity for Port mirroring, not a feature
Hi Vullis,
Did the exam match up to questions asked in this forum? Just trying to work out study plan.
VDS also supports ERSPAN capability where you will not require any configuration changes on the physical switches. You just need the IP address of the destination virtual machine or analyzer. Just select the “Encapsulated Remote Mirroring (L3) source” option for the session type and walk step-by-step through the wizard. For the source select the ports you want to monitor and for the destination enter the IP address of the virtual machine or analyzer.
