20+ practice questions focused on Protocols And Endpoints — one of the most tested topics on the Cisco Implementing Cisco Collaboration Core Technologies (CLCOR, 350-801, v2.0 blueprint, CCNP Collaboration) (CLCOR) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Protocols And Endpoints PracticeA Webex Desk Pro is failing to provision via the Cisco Webex Control Hub. The device displays 'Provisioning Error'. Which configuration component is primarily responsible for holding the authentication credentials required for the device to pull its configuration?
Explanation: The Activation Code is the primary component that holds the authentication credentials for a Webex Desk Pro to provision via Control Hub. When entered on the device, it securely associates the device with the organization and allows it to pull its configuration. Without a valid activation code, the device cannot authenticate to Control Hub.
An endpoint using the Opus codec is experiencing one-way audio. The SDP exchange indicates that the endpoint is offering a wideband range. Where in CUCM would you modify the Region settings to force the use of a specific codec for this endpoint?
Explanation: Codec selection between regions is controlled by CUCM Region settings, where you configure the maximum audio codec (e.g., G.722, Opus, G.711) allowed for calls between devices in those regions. To force a specific codec for the endpoint, you modify the Region configuration that applies to its device pool's region pair.
A Cisco IP Phone 8841 is failing to register to Cisco Unified Communications Manager. You check the phone settings and see the TFTP server address is correct. Which protocol and port should you monitor on the gateway or firewall to verify the initial registration attempt?
Explanation: The Cisco IP Phone 8841 is a SIP endpoint by default, and its initial registration signaling to Cisco Unified Communications Manager uses SIP over UDP port 5060 (or TCP 5060). Since the TFTP address is already correct, the next step in the registration sequence is the SIP REGISTER exchange, so monitoring SIP UDP 5060 on the firewall/gateway verifies whether the registration attempt reaches CUCM.
You are configuring a G.729 codec for a WAN link. To ensure that the voice quality remains acceptable while minimizing bandwidth, which feature must be enabled to prevent excessive packet overhead?
Explanation: VAD (Voice Activity Detection) suppresses silence, saving bandwidth, but is often recommended to be disabled if voice quality is the primary concern, or enabled to conserve bandwidth.
You need to verify that an endpoint is correctly sending RTCP reports to Cisco Unified Communications Manager. Which field in the RTCP packet header would you examine to track the jitter statistics?
Explanation: The Interarrival Jitter field in the RTCP packet header carries the jitter statistics, which measure the variation in packet arrival times. This field is part of the RTCP Receiver Report (RR) and is used to assess media stream quality. Examining it allows you to verify that endpoints are reporting jitter correctly to CUCM.

Practice all Protocols And Endpoints questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Protocols And Endpoints. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Protocols And Endpoints questions on the CLCOR frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Protocols And Endpoints is tested as part of the Cisco Implementing Cisco Collaboration Core Technologies (CLCOR, 350-801, v2.0 blueprint, CCNP Collaboration) (CLCOR) blueprint. Practicing with targeted Protocols And Endpoints questions ensures you can handle any format or difficulty that appears.
