Agreed. I wouldn't know the answer to this nor do I care
Not because it's not important and not because i couldn't figure it out, but
because it's like asking me to implement the spec.. Now if you asked me about
what a bgp marker or mp-nlri looks like I can answer that. Same goes for why

Long long time ago I was asked a good one: is ospf TCP or udp.
Thankfully I knew the answer.

Override the dynamic (e.g. DHCP) default route. Often so you can
implement a workaround that central Network Security wouldn't approve

The main idea was to execute a first level of filtering to separate
the candidates that put information in their CV that does not match
with the basic requirements for the position.
For example:
