What does the alarm j°SPFZZ/IFAUTFAIL indicate when a packet is received?

• A. Incorrect interface authentication configuration
• B. Inconsistent Hello intervals
• C. Unmatched subnet masks
• D. Inconsistent area IDs

Answer: (A)

The alarm j°SPFZZ/IFAUTFAIL signifies an issue with interface authentication when a packet is received. This specific alarm suggests that there is an incorrect configuration related to interface authentication between devices. In networking, proper interface authentication is essential to ensure that only authorized devices can communicate across the network. When authentication is misconfigured—such as mismatching passwords or security settings—it triggers this particular alarm. Understanding that interface authentication settings must be consistent on both ends of a connection underscores the importance of having the correct configurations to facilitate reliable communication. While the other options mention various configurations, such as Hello intervals, subnet masks, and area IDs, those do not directly pertain to authentication failures but rather to different elements of network communication protocols or routing configurations.
