I've been taking the online test at mylearn.vmware.com, and have discovered the following question.
I can't figure it out entirely.
The VM cannot talk on the network after vMotion from sales B to sales A because the VLAN tag ID is wrong.
There's a question about which host A or B has a invalid native uplink. Which is correct?
An administrator determines that a virtual machine configured for the Sales port group lost network connectivity when it was migrated with vMotion from one ESXi 5.x host to another. The administrator notices that machines configured for the Marketing port group are not experiencing the issue. The hosts have port groups with the following network configuration:
Host A:
Host B:
Choose two.
the answers are
The configured VLAN for Development on Host B is incorrect.
and
An improper native VLAN is configured on the uplinks to Host A.
We are told there is an error on that portgroup, we are shown that the config doesn't match. We need to identify what could be different
1 is not correct as Prod has no issue
2 could be correct as there is a VLAN configured for Dev on B - which doesn't match the config we see on A.
3 could be correct, since there is no VLAN associated with Dev on "A" the traffic will depend on the native VLAN of the uplink
4 is not correct as both portgroups on B have associated VLAN tags so the native VLAN won't be used
Which online test at mylearn.vmware.com are you taking? I see a similar question, but not that exact one.
Either:
Host A Sales needs a VLAN tag
Host A Sales needs the uplink needs to be configured as an access port for VLAN 20
Host B needs the VLAN tag removed
Host B has the wrong the VLAN tag applied
Host B needs the uplink configured for trunking on VLAN 20 (ie, to pass the VLAN tags)
I modified the names and VLAN ids because I didn't know if the questions were copyrighted and it was covered under fair use.

Ok so the answers from the item, changed to fit your scenario are:
1 Host A Marketing VLAN is incorrect
2 Host B Sales VLAN is incorrect
3 native VLAN wrong somewhere on Host A
4 native VLAN wrong somewhere on Host B
We are told there is an error on that portgroup, we are shown that the config doesn't match. We need to identify what could be different
1 is not correct as Marking has no issue
2 could be correct as there is a VLAN configured for Sales on B - which doesn't match the config we see on A.
3 could be correct, since there is no VLAN associated with Sales on "A" the traffic will depend on the native VLAN of the uplink
4 is not correct as both portgroups on B have associated VLAN tags so the native VLAN won't be used
Here is the original question: Q: | |
An administrator determines that a virtual machine configured for the Development port group lost network connectivity when it was migrated with vMotion from one ESXi 5.x host to another. The administrator notices that machines configured for the Production port group are not experiencing the issue. The hosts have port groups with the following network configuration: Host A:
Which two conditions would explain the loss of network connectivity for the virtual machine? (Choose two.) | |
A: | |
The configured VLAN for Production on Host A is incorrect. | |
The configured VLAN for Development on Host B is incorrect. | |
An improper native VLAN is configured on the uplinks to Host A. | |
An improper native VLAN is configured on the uplinks to Host B. |
What is the correct answer?
Inproper vLAN for host A is not an option.
If you select vLAN for host B (on the assumption it's present when it should not be) it says that's not the correct answer.
Choose two.
the answers are
The configured VLAN for Development on Host B is incorrect.
and
An improper native VLAN is configured on the uplinks to Host A.
