I thought _sips._udp was a thing too, but I guess not?

Wait, is C even a real record? Sounds off.

I’m pretty confident that _h323ls._udp is valid, but I’m uncertain if _sips._tcp is the right choice or if it should be _sips._udp instead.

I feel like there was a question similar to this in our last mock exam, but I can't recall if both SIP records were TCP or if one was UDP.

I remember practicing with SRV records, and I think _h323ls._tcp is definitely one of the valid options for H.323 communication.

I think the SRV records for SIP should start with _sips, but I'm not sure about the transport protocol. Was it TCP or UDP?

I'm a bit confused by the question. I know SIP uses SRV records, but I'm not sure about the exact syntax for H.323. I'll make an educated guess and select the TCP options for both protocols.

Let me think this through step-by-step. SIP uses TCP, so the first option is correct. H.323 can use either TCP or UDP, so I'll select both _h323ls._tcp.example.com and _h323ls._udp.example.com.

Okay, I've got this! The valid SRV records for SIP and H.323 are _sips._tcp.example.com and _h323ls._tcp.example.com. I'm confident in those choices.

Hmm, I'm a bit unsure about the differences between SIP and H.323 protocols. I'll need to double-check the valid record types for each.

This looks like a DNS question, so I'll need to review my knowledge of SRV records and the proper syntax for SIP and H.323 services.

I heard the exam proctors are big fans of dad jokes. Maybe I should throw in a 'Who's on TCP, What's on UDP?' joke. That'll really impress 'em!

Wait, hold up, is this a trick question? I bet the answer is E - it's called 'collab-edge', so it must be the right choice, right? *wink wink*
