Wait, are we sure it’s not the SAN switch on siteA_2?

Totally agree, the connection failures point to the bridge.

I’m not so sure, could it be the ISL instead?

Definitely, those bridge removal messages are a big red flag.

Looks like the ATTO bridge on siteB_2 is the culprit.

I practiced a similar question, and I feel like the ATTO bridge on siteB_2 could be the culprit since it's mentioned in the logs.

The repeated "notConnected" errors make me think it's related to the SAN switches, but I can't recall which site specifically.

I think the messages indicate that both nodes are having trouble with the HA interconnect, which might suggest a problem with the ISL between siteA and siteB.

I remember something about the ATTO bridges being critical for connectivity, but I'm not entirely sure if it's the one on siteB_2 causing the issue.

This is a tricky one. The question is a bit vague, and I'm not entirely sure what they mean by the "networking plane." I'll have to review my notes on Huawei's distributed storage system architecture to see if I can figure out the right answer. Might be worth skipping this one for now and coming back to it later.

I'm a little confused on this one. I know we talked about security incident response, but I can't recall the specific table name. I'll have to review my notes and try to eliminate the options that don't seem quite right.

A view, definitely. That way, the query is saved and can be reused, and the calculated columns will be included. Seems like the most straightforward solution to me.
