JNCIP-DC: Juniper Networks Certified Professional – Data Center (2021) — Question 1

You want to converse IP address space and reduce your fabric management overhead. For these reasons, you decided to use unnumbered Ethernet interfaces for your IP Fabric.
Which statement is correct in this scenario?

Answer options

• A. The donor interface for an unnumbered interface must have only one configured IP address.
• B. PIM is not supported on upstream unnumbered interfaces in the PIM topology.
• C. OSPF is supported on unnumbered interfaces configured as a point-to-point connection.
• D. Only the IPv4 address family is supported on the interfaces.

Correct answer: D

Explanation

The correct answer is D because unnumbered interfaces primarily support the IPv4 address family for operation. Options A and B are incorrect as they misstate the requirements and capabilities of unnumbered interfaces. Option C is misleading since OSPF can indeed function on unnumbered interfaces, but the question specifically asks for the supported address families.
