I want to say it's 64 bits, but that doesn't sound right. I should have reviewed this more!

I feel like I might confuse this with IPv6, which is longer. Is it really just 32 bits for IPv4?

I remember practicing a question like this, and I think the answer was definitely A, 32 bits.

This looks like a tricky BGP policy question. I'll need to carefully read through the policy statement and understand how the prefix lists are being used.

Okay, let me think this through. I believe the two steps are "Enable the Failover Check box" and "Assign the subscriber to the redundancy group". I'll double-check my answer before submitting.

I'm a bit nervous about this one. These all sound similar but slightly different. I'll make sure to read each option carefully and look for any potential tricks.
