Dell EMC Associate – Information Storage and Management v4 — Question 1

What is an accurate statement about stretched VLANs?

Answer options

• A. Reduces network bandwidth requirements during VM migration across sites.
• B. Requires a change in the VMs' IP addresses to match the addressing scheme at the other sites.
• C. Enables automatic modification of VLAN addresses during VM migration across sites.
• D. Supports migration of VMs across sites without the need to change their network configurations.

Correct answer: A

Explanation

Option A is correct because stretched VLANs do indeed help to minimize bandwidth usage during VM migrations across different locations. Option B is incorrect as stretched VLANs allow VMs to maintain their IP addresses, so no changes are necessary. Option C is also wrong because VLAN addresses do not change automatically during migrations; they remain consistent. Option D, while partially true, does not highlight the bandwidth benefits that A does.
