Refer to the exhibit. Given this "debug isdn q921" output, what is the problem with the PRI?

Show Suggested Answer Hide Answer
Suggested Answer: C

Balanced mode provides user load balancing and user failover in the event of an outage. Active/standby mode provides an always on standby node in the event of an outage, but it does not provide load balancing.

Here is a more detailed explanation of the two modes:

Balanced mode:In balanced mode, the IM and Presence Service nodes are configured to work together to provide high availability. The nodes are configured in a redundancy group, and the system automatically balances the load of users across the nodes in the group. If one of the nodes fails, the system automatically fails over the users to the other nodes in the group.

Active/standby mode:In active/standby mode, one of the IM and Presence Service nodes is designated as the active node, and the other nodes are designated as standby nodes. The active node handles all of the user traffic, and the standby nodes are only used if the active node fails. If the active node fails, the system automatically fails over to one of the standby nodes.

I thought the IP address was the main problem here?

The PRI is sending keepalives, so it's not that bad.

I’m pretty sure if Layer 1 is down, it would affect the whole connection, so I might go with option D, but I need to double-check that.

I feel like the output might indicate a configuration issue, but I can't recall if it specifically mentioned an IP address for the PRI.

I think I saw a similar question in our practice tests where Layer 2 was down, so I might lean towards option B.

Aha, the key here is to identify the layer that's down. The debug output seems to indicate a layer 2 issue, so I'll go with option B.

Hmm, the debug output shows some keepalives, so maybe the PRI is actually working fine? I'll have to think this through.

Definitely looks like a layer 2 problem to me. That debug output is pretty clear on that. I'd start troubleshooting the controller interface and cabling.
