質問 # 86
An administrator installs a new webserver (server1.example.com - 10.1.1.90) for storing Cisco Jabber update files to the network, but all Mobile and Remote Access registered clients still run the old Jabber software version, and the update fails.

質問 # 92
Cisco Jabber clients are failing to log in using Mobile and Remote Access. The administrator checked the Jabber problem report logs and saw that connections to the Expressway-E are being refused on TCP port 8443. From a packet capture run on the Jabber client while attempting to log in, there is no response to the TCP SYN packets sent to the Expressway-E by Jabber.
Which two reasons are causing the Expressway-E to be unreachable on port 8443 from the internet? (Choose two.)
- A. The SRV record for _cisco-uds is misconfigured.
- B. The Jabber clients using an outdated version.
- C. The certificate for Jabber is expired.
- D. The Unified Communications zone is down.
- E. The firewall is blocking the port.
正解：D、E
解説：
Traffic is coming from the internet so can not be the cisco_uds record, as it is created on the internal DNS only. Collab_edge is the external DNS record. It has to be port blocked or traversal zone down.
