Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 75

Other than a working EIGRP configuration, which components must be the same on all routers for EIGRP authentication key rollover to work correctly?

Answer options

• A. SMTP
• B. time
• C. SNMP
• D. passwords B

Correct answer:

Explanation

The correct answer is B. For EIGRP authentication key rollover to work, the time on all routers must be synchronized to ensure that the keys are valid at the same time. Options A (SMTP) and C (SNMP) are unrelated to EIGRP authentication, while option D (passwords B) is not specific to the key rollover process.
