300-420 Question 27
Select 2An enterprise network engineer is designing a multi-protocol campus network that will support both IPv4 and IPv6 communication. The design must ensure that the routing protocols used in the network can operate effectively with both address families. Which address families must be configured on the routing protocols to achieve this goal?
- A
IPv4 Unicast
- B
IPv6 Unicast
- C
IPv6 Multicast
- D
VPNv4
- E
IPv4 Multicast
Show answer and explanation
Correct answers: A, B
Explanation
To support both IPv4 and IPv6 communication in a multi-protocol campus network, the routing protocols must be configured to handle both IPv4 Unicast and IPv6 Unicast address families. These address families ensure that routing information is exchanged for IPv4 and IPv6 traffic. Other address families like multicast or VPN-specific families are not required unless explicitly stated in the design requirements.
- A. Correct.
IPv4 Unicast is a primary address family that must be configured for routing IPv4 traffic. It is essential to support IPv4 in the network.
- B. Correct.
IPv6 Unicast is a primary address family needed to route IPv6 traffic effectively. Since the scenario requires IPv6 communication, this must be configured.
- C. Incorrect.
IPv6 Multicast is used to support multicast traffic in an IPv6 network. However, the scenario does not mention multicast traffic requirements, so it is not necessary here.
- D. Incorrect.
VPNv4 is used in MPLS VPN implementations to support routing in a VPN environment. This is not relevant for the given campus network scenario.
- E. Incorrect.
IPv4 Multicast is used to support multicast traffic in an IPv4 network. Similar to IPv6 Multicast, the scenario does not specify multicast requirements, so it is not needed.
