Explanation/Reference:
Explanation:
B: DHCP Option 43
Option 43 is not really a single option but a number of sub-options which tell the phone where to locate the Certificate Provisioning service on the Lync server.
D: DHCP Option 120
Once the certificate is downloaded to the phone then a valid Lync registrar server needs to be located. The value of Option 120 will be the FQDN of the Lync server which will handle authentication requests from the phones.
