R1 and R2 are using VRRP for high availability.
Referring to the exhibit, which two statements are correct about the configuration? (Choose two.)

Answer options

• A. R2 is the backup router and will become the master router if ge-1/0/0 on R1 goes down.
• B. R2 is the backup router and will remain the backup router if ge-1/0/0 on R1 goes down.
• C. If R1 goes down, R2 will become the master and will relinquish mastership once R1 comes back online.
• D. If R1 goes down, R2 will become the master and will remain the master once R1 comes back online.

Correct answer: B, C

Explanation

Option B is correct because R2 is configured to remain the backup router despite R1's ge-1/0/0 interface going down. Option C is also correct since R2 will take over as the master if R1 fails and will relinquish that role once R1 comes back online. Options A and D are incorrect because they misinterpret the behavior of R2 in relation to its backup role and the retention of mastership.
