Which two DNS records must be created to configure Service Discovery for on-premises Jabber? (Choose two.)

Question

Options

• A_cuplogin._tcp.cisco com pointing to a record of IM&P
• B_cisco-uds._tcp.cisco.com pointing to a record of Cisco Unified CM
• C_cuplogin._tls.cisco.com pointing to the IP address of IM&P
• D_cisco-uds._tls.cisco.com pointing to the IP address of Cisco Unified Communications manager
• E_xmpp._tls.cisco.com pointing to a record of IM&P

• A
  93% (39)
• C
  2% (1)
• E
  5% (2)

Explanation

For on-premises Jabber service discovery, two DNS SRV records are required: (1) '_cisco-uds._tcp.<domain>' pointing to a CUCM node, which allows Jabber to discover CUCM for call control and directory services; and (2) '_cuplogin._tcp.<domain>' pointing to a Cisco IM and Presence (IM&P) node, which allows Jabber to discover the IM&P server for instant messaging and presence. Both use the TCP transport protocol (not TLS) in the SRV record name. Option C and D are incorrect because '_cuplogin._tls' and '_cisco-uds._tls' are not valid service discovery record names for on-premises Jabber. Option E (_xmpp._tls) is not used in standard Cisco on-premises Jabber service discovery.
