B. you can double check the official Cisco documentation or practice with lab DNS configs if you want to be sure.
Option C for sure, "Maximum Number of Registered Devices" is the key setting. Option A adds unregistered devices, which isn't needed here. Seen similar questions trip folks up in practice tests, but C matches exactly.
C , that's what I've seen in similar exam reports for Expressway setups.
I thought A might be right since it mentions both registered and unregistered devices, but in similar exam questions the official guide emphasizes adjusting that "Maximum Registered Devices" value instead. Anyone else see references to A in practice test explanations?
Option C, Pretty sure A is a trap since unregistered devices don't affect the actual registration cap here.
B here since the SRV with _tls is what actually gets used for MRA in external DNS. Cisco docs and most config guides call for _collab-edge._tls. Pretty sure this is right unless something major changed.
C , that's what you'd adjust in practice. Recommend checking the official guide and labbing to see how the parameter impacts registration.
C vs A. Pretty sure it's C here because that parameter specifically limits the count of registered phones per node. A tries to trip you up by lumping in unregistered devices, which isn't what the question asks for. Let me know if you see it differently.
Its C, A trips people up but it's for both device types not just registered.
Probably C for this one.
