Remote Access solution?
It’s C because _collab-edge._tls is the standardized SRV record for MRA in public DNS, while D is more specific to Expressway internal setups, not always for the external DNS entry.
It’s D since _cisco-expwy._tls is also used for Cisco Expressway, which handles MRA traffic externally. C is common, but D fits well for external DNS SRV entries in many MRA setups too.
C, it matches the known SRV record for public Cisco MRA setups.
Eliminate A and B—they’re not standard for public DNS SRV entries in Cisco MRA.
It’s C because _collab-edge._tls is the standard SRV record used for external Cisco MRA DNS entries. The others don’t match common Cisco documentation for public DNS SRV records.
Option C makes the most sense since _collab-edge._tls is what Cisco docs usually mention for MRA SRV records. The others either use wrong prefixes or protocols. For example, A uses _tcp instead of _tls, which is needed for secure connections in MRA. So even without version info, C fits best with current Cisco Mobile and Remote Access setups.
John J.: Does the question specify the exact Cisco MRA version or deployment type? That might affect which SRV record is correct here.
