Question 223 · 450 in bank
Refer to the exhibit. CUBE_1 and CUBE_2 must use the G.729r8 codec when communicating. Which action completes the configuration?
Show answer
Answer: B
Explanation
Question states that the call must use G.729r8, which means CUBE_2 needs to be able to "speak" G.729r8, instead of G.729br8 currently configured. The first step towards CUBE_2 supporting G.729r8 is configuring a voice class with G.729r8 as one of the options. Hence I am going with Answer B. A codec voice class is a construct within which a codec preference order can be defined. A codec voice class can then be applied to a dial peer, which then follows the preference order defined in the codec voice class. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/voice/cube/configuration/cube-book/voi-negt-aud-code.html

Question 228 · 450 in bank
Refer to the exhibit. In Cisco UCM, an engineer must create a new SIP route pattern that must be reachable by all Internal callers. The internal callers have a calling search space named CSS_INTERNAL that includes a partition named PT_INTERNAL. The SIP trunk has a calling search space named CSS_SIP_RP that includes the two partitions named PT_SIP_INTERNAL and PT_SIP_LOCAL. What must be used as the route partition for the SIP route pattern?
Show answer
Answer: D
Explanation
Answer is D Routepattern or SIP Route pattern is something that is directing from CUCM to a different/outside destination - > Phone has to reach this pattern. Sip-Trunk CSS is not required at all, because SIP-Trunk only use "incoming CSS" for routing decisions Phone CSS_INTERNAL PT_INTERNAL Trunk CSS_SIP_RP PT_SIP_INTERNAL PT_SIP_LOCAL

Question 230 · 450 in bank
Refer to the exhibit. An engineer is troubleshooting an NTP synchronization issue that returns a message of ‘unsynchronized’ when the utils ntp status command is run on the Cisco UCM subscriber node. The connectivity between the subscriber and the NTP server was verified as working, and the NTP server is running. Which action resolves the issue?
Show answer
Answer: D
Explanation
Definitely D. CUCM publisher needs an NTP source that is not a member of the CUCM cluster; therefore the CUCM publisher synchronizes its time with the NTP server. In this exchange, the CUCM publisher is an NTP client. The CUCM subscribers synchronize their time with the CUCM publisher. In this exchange, the CUCM publisher is an NTP server where the CUCM subscribers are NTP clients. https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/215537-network-time-protocol-ntp-on-cucm.html .INIT. means that initialization has not yet succeeded. Probable causes of NTP issues in CUCM: - External NTP server is not reachable. - NTP stratum is higher than the acceptable limit. - Publisher is down, so the Subscriber NTP is unsynchronized. https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/118718-technote-cucm-00.html
