C is misleading, SET values do override postgresql.conf for the session only.

I think I practiced a similar question where we discussed the priority of SET versus postgresql.conf, and I believe SET has higher priority.

I'm a bit unsure about option D; I thought SET changes only apply to the current session, not future connections.

I remember that the SHOW command is definitely used to check parameter values, so that one seems correct.

Okay, let me think this through. I know there are some parameters that can only be set in the config file, not at runtime. I'll need to remember that.

Hmm, I'm not too familiar with the Cisco Unified JTAPI implementation. I'll have to try to recall what I know about the different types of endpoints it supports.

The key here is that the technology is new and there's uncertainty about its longevity and reliability. I think the risk register is the way to go to document and manage those risks.

Ugh, I'm really struggling with this one. Virtualization is such a complex topic, and I'm not sure I fully grasp all the security implications. I'll have to guess and hope for the best.

A superuser with the power to change settings? I bet they're the ones who decide when to restart the database for 'maintenance'.
