The security administrator is reviewing the business continuity plan which consists of virtual

infrastructures at corporate headquarters and at the backup site. The administrator is concerned
that the VLAN used to perform live migrations of virtual machines to the backup site is across the
network provider’s MPLS network. This is a concern due to which of the following?

A.
The hypervisor virtual switches only support Q-in-Q VLANS, not MPLS. This may cause live
migrations to the backup site to fail.

B.
VLANs are not compatible with MPLS, which may cause intermittent failures while performing
live migrations virtual machines during a disaster.

C.
Passwords are stored unencrypted in memory, which are then transported across the MPLS
network.

D.
Transport encryption is being used during the live migration of virtual machines which will
impact the performance of the MPLS network.
