Honestly, these port questions are always vague. I'm putting D and F.
Nah, closing D would break DNS but A and C are insecure defaults. A, C.
Its A and C. 21 is FTP and 23 is Telnet, both send data unencrypted. I think some might pick B (SSH) but that's actually needed for secure admin access.
Option B and F. SSH (22) and LDAPS (636) are sometimes left open when not needed, so I usually pick those. Port 21 looks like a trap since some practice exams swap it out, but not fully sure.
B tbh, but not sure since it depends if those services are actually needed. Maybe A and C are better picks.
Nah, not B or D. A and C are right here since FTP (21) and Telnet (23) are known for being super insecure, classic trap for leaving those open from older setups.
A C tbh, lots of practice tests say those are risky, official guide covers these ports too.
A and C
A C, saw this same combo in a mock exam and that's what I picked.
A and C make sense since FTP (21) and Telnet (23) both send stuff unencrypted. Those are usually the first to close for better security. Not 100% but pretty sure that's what they're after here, agree?
