20+ practice questions focused on Infrastructure And Design — 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 Infrastructure And Design PracticeYou are performing a network readiness assessment for a Cisco Webex Room Kit deployment. The current network uses a legacy infrastructure with a MTU of 1500 bytes. What is the recommended practice for handling potential fragmentation issues for video traffic streams?
Explanation: Video traffic is sensitive to jitter and delay. Ensuring that the network supports a larger MTU or preventing fragmentation by sizing packets correctly is critical.
You are designing a high availability solution for Cisco Unity Connection. Which service must be running and correctly configured on both the primary and secondary servers to facilitate automatic failover?
Explanation: Cisco Unity Connection uses the Connection High Availability service to synchronize data and heartbeat between the cluster nodes.
You are designing a Cisco Unified Communications Manager (CUCM) cluster with geographically dispersed nodes. To ensure optimal voice quality and call signaling efficiency, which mechanism should you configure to prevent the transmission of unnecessary SIP signaling traffic over high-latency WAN links?
Explanation: SIP proxy timers and keepalive settings are critical for WAN links, but configuring SIP Trunk SIP Profile timers allows for better management of transaction timeouts across high-latency links.
You are deploying a Cisco Expressway-E in a DMZ. Which port must be opened on the external firewall to allow for H.460.18/19 firewall traversal for H.323 endpoints?
Explanation: H.460.18/19 is an ITU-T standard for H.323 firewall traversal, and it uses the standard H.323 call signaling port TCP 1720 for the initial Q.931 call setup. The Expressway-E listens on TCP 1720 to accept traversal calls from external H.323 endpoints, after which H.460.19 multiplexes media over the same connection. Therefore, port 1720 must be opened on the external firewall to allow H.323 endpoints to register and place calls through the Expressway-E.
You have a CUCM cluster with high utilization. Which parameter, when adjusted, helps mitigate the load on the TFTP service during a large-scale phone deployment?
Explanation: The TFTP File Load Factor parameter controls how many TFTP requests a CUCM TFTP server handles simultaneously. Adjusting this parameter helps mitigate TFTP service load during large-scale phone deployments by limiting concurrent file transfers, preventing server overload. This is a specific CUCM service parameter under Cisco TFTP.

Practice all Infrastructure And Design questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Infrastructure And Design. 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
Infrastructure And Design 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. Infrastructure And Design 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 Infrastructure And Design questions ensures you can handle any format or difficulty that appears.
Yes. Courseiva provides free CLCOR practice questions across all exam topics and domains. The platform includes topic-based practice, mock exams, missed-question review, bookmarked questions, and readiness tracking — no account required.
Difficulty is subjective, but Infrastructure And Design is a high-priority exam concept tested in multiple ways — direct recall, scenario analysis, and command-output interpretation. Consistent practice is the best way to build confidence.
