Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 159

A company is expanding its existing office space to a new floor of the building, and the networking team is installing a new set of switches. The new switches are running IGMPv2, and the engineers configured them for VLAN10 only. The rest of the existing network includes numerous Layer 2 switches in multiple other
VLANs, all running IGMPv3. Which additional task must the team perform when deploying the new switches so that traffic is switched correctly through the entire network?

Answer options

• A. Configure the new switches to use IGMPv3 on all VLANs on the network.
• B. Configure all switches on the network to support IGMPv2 and IGMPv3 on all VLANs on the network.
• C. Configure the new switches to use IGMPv3 on VLAN10 only.
• D. Configure all switches on the network to support IGMPv2 and IGMPv3 on VLAN10 only.

Correct answer: C

Explanation

The correct answer is C because the new switches need to be configured to use IGMPv3 for VLAN10 to be compatible with the existing network that is operating on IGMPv3. Options A and B suggest broader changes that are unnecessary and do not address the specific VLAN10 requirement. Option D also does not facilitate the needed compatibility for VLAN10 with IGMPv3.
