JNCIA-Junos: Juniper Networks Certified Associate – Junos (legacy) — Question 4

You accidentally configured interface so-0/0/0.0 with /32 instead of /30.
Which two solutions could you use to correct this configuration? (Choose two.)

Answer options

• A. [edit interfaces so-0/0/0.0] user@router# replace family inet address /32 with /30
• B. [edit interfaces so-0/0/0.0] user@router# rename family inet address /32 to address /30
• C. [edit] user@router# replace interface so-0/0/0.0 family inet address /32 with address /30
• D. [edit interfaces so-0/0/0.0] user@router# delete family inet address

Correct answer: B, D

Explanation

Option B is correct because it allows you to change the existing address from /32 to /30 directly. Option D is also valid as deleting the incorrect /32 address allows you to then configure the correct /30 address from scratch. The other options (A and C) are incorrect because they do not provide a valid command syntax for changing the address type in this context.
