  A collaboration engineer needs to replace the original, single NTP server that was configured during the initial install of a Cisco UCM server. What is the first step to accomplish this task?

  A. Stop the NTP service on Cisco UCM.

  B. Enable NTP authentication for the new NTP server on Cisco UCM.

  C. Restart the NTP service on Cisco UCM.

  D. Delete the original NTP server from Cisco UCM.

  Correct Answer: D

  If you look at the exhibit on the "utils ntp status", it shows two original servers installed. And if you ready the question carefully, there is a "," after "original,", which means, from two original NTP servers, only single NTP server needs to be delete. So you can delete a single NTP server from the two listed NTP servers. However, even if there is only one server, you can't enable authentication for the new NTP server, you need first add it, then enable it with command “utils ntp auth symmetric-key enable” which you get prompt to select for enable the authentication for the listed servers:

  admin:utils ntp auth symmetric-key enable At the end, nothing in the question mentioned about NTP authentication, as you can see authentication report with the following command: admin:utils ntp auth symmetric-key status

• Question 229:

  Refer to the exhibit.

  

  There is a call flow between Phone A and Phone B. Phone B (holder) places Phone A (holdee) on hold. Which MRGL and Audio Source are played to Phone A?

  A. MRGL A and Audio Source 4

  B. MRGL B and Audio Source 2

  C. MRGL B and Audio Source 4

  D. MRGL A and Audio Source 2

  Correct Answer: D

  In simplest terms, the holder's configuration determines which audio file to play, and the holdee's configuration determines which resource or server will play that file. As illustrated by the example in Figure 18-1, if phones A and B are on a call and phone B (holder) places phone A (holdee) on hold, phone A will hear the MoH audio source configured for phone B (Audio-source2). However, phone A will receive this MoH audio stream from the MRGL (resource or server) configured for phone A (MRGL A). https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/8x/moh.html#wp1092723
