JNCIP-DC: Juniper Networks Certified Professional – Data Center (2023) — Question 36

A customer wants to connect two data centers on different subnets using EVPN.
What are two implications of using different IP subnets at each site? (Choose two.)

Answer options

• A. MAC addresses will not need to be advertised between the data centers.
• B. MAC addresses will need to be advertised between the data centers.
• C. Using different IP subnets at each site allows Layer 3 gateways to exchange only type-3 routes.
• D. Using different IP subnets at each site allows Layer 3 gateways to exchange only type-5 routes.

Correct answer: B, D

Explanation

The correct answer is B and D. MAC addresses must be advertised between the data centers to ensure proper communication. Additionally, using different IP subnets allows Layer 3 gateways to exchange only type-5 routes, which are related to Ethernet segment routes, while type-3 routes pertain to IP prefixes and are not exclusively exchanged due to the subnet differences.
