An administrator troubleshoots a DNS issue with Cisco UCM and observes that the hostname resolution returns the wrong IP address. The DNS team informs the administrator that the A/AAA record was recently updated on the DNS server. Which action must be taken on Cisco UCM to reflect the correct entries?
Answer: B
An engineer has a Cisco UCM cluster on version 12.5(1). The engineer registered and configured a new Cisco IP phone 8851 to Cisco UCM and assigned it to a user. If the message on Cisco UCM says "Rejected," this issue should be addressed by pressing the gear button on the phone and choosing administrator settings. What is the next step that the engineer must take to resolve the issue?
Answer: B
Refer to the exhibit. An engineer must provide a list of codecs based on the media attribute of an SDP body snippet. Which codecs are included in the media attribute ordered by priority?
Answer: D
Refer to the exhibit. An administrator is attempting to register a SIP phone to a Cisco UCM but the registration is failing. The IP address of the SIP Phone is 10.117.34.222 and the IP address of the Cisco UCM is 10.0.101.10. Pings from the SIP phone to the Cisco UCM are successful. What is the cause of this issue and how should it be resolved?
Answer: D
Refer to the exhibit. An INVITE with the SDP in the exhibit is received. Based on the configuration, which two codecs will be in the SDP of the outbound INVITE? (Choose two.)
Answer: CD
If a trust boundary is placed on a Cisco IP phone, what occurs with the packets that come to the phone from a PC?
Answer: B
In a Cisco IP phone deployment with a trust boundary on the phone, the phone typically does not trust the traffic coming from a connected PC. As a result, the phone does not mark the CoS (Class of Service) values for packets received from the PC. Instead, the access switch, which is typically configured to trust the phone's markings, will set or enforce the appropriate CoS values based on the network's QoS policies.

Answer: C
from: https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/jabber/11_9/Unified-CM-OAuth-Whitepaper-v17-FINAL.pdf we found this: The tokens are self-contained, meaning that the UC service trusts tokens it can open and validate without communicating with the OAuth server. Tokens use the RFC-based JSON Web Token (JWT) format. I changed my last comment. ANSWER is C
