- Question 1Service-Related Knowledge
What do 'show interfaces' status values 'up/up' and 'up/down' indicate?
Show Answer & Explanation
Correct Answer: BExplanation:Line status/Protocol status: up/up = fully operational (L1+L2). up/down = physical link is active but L2 protocol failed (encapsulation mismatch, keepalive failure, clocking issue). down/down = physical issue (no cable, no signal). admin down = shutdown.
- Question 2Service-Related Knowledge
What is the purpose of the 'show tech-support' command in troubleshooting?
Show Answer & Explanation
Correct Answer: BExplanation:'show tech-support' collects extensive diagnostic information including show version, running-config, interfaces, processes, and more into a single output commonly requested by TAC engineers.
- Question 3Service-Related Knowledge
What is the recommended first troubleshooting step when a Cisco switch port is showing 'err-disabled' status?
Show Answer & Explanation
Correct Answer: CExplanation:First identify why the port was err-disabled using 'show errdisable recovery' or 'show interface status err-disabled'. Common causes include BPDU guard, port security, or link-flap. Fix the root cause before re-enabling.
Key Troubleshooting Concepts for CCT
CCT Troubleshooting Exam Tips
Basic Troubleshooting questions in CCT are typically scenario-based. Focus on service-level decision making aligned to official exam objectives. Priority concepts: troubleshoot, show, ping, traceroute, interface status, log.
What CCT Expects
- Anchor your answer in select the most practical, secure, and scalable answer for the stated scenario.
- Troubleshooting scenarios for CCT are frequently mapped to Domain 3 (35%), so read the objective carefully before picking controls or architecture.
- Expect multi-service scenarios where Troubleshooting interacts with IAM, networking, storage, or observability patterns rather than appearing as an isolated service question.
- When two options are both technically valid, prefer the choice that best aligns with the exam's operational scope (Entry) and managed-service best practices.
High-Value Troubleshooting Concepts
- Know the core Troubleshooting building blocks cold: troubleshoot, show, ping, traceroute.
- Review the edge-case features and limits for interface status, log; these details are commonly used to differentiate answer choices.
- Practice service-integration reasoning: how Troubleshooting pairs with Hardware, IOS Basics in real deployment patterns.
- For CCT, explain why the chosen Troubleshooting design meets reliability, security, and cost expectations better than the alternatives.
Common CCT Traps
- Watch for answers that partially solve the requirement but miss operational constraints.
- Questions in Troubleshooting often include distractors that look correct for Troubleshooting but violate least-privilege, durability, or availability requirements.
- Avoid picking options purely by feature name; validate data path, failure handling, and governance impact before answering.
- If the prompt hints at automation or repeatability, eliminate manual-only operational answers first.
Fast Review Checklist
- Can you compare at least two Troubleshooting implementation paths and justify which one best fits the scenario?
- Can you map the chosen answer back to Troubleshooting (35%) outcomes for CCT?
- Can you explain security and access boundaries for Troubleshooting without relying on default-open assumptions?
- Can you describe how Troubleshooting integrates with Hardware and IOS Basics during failure, scaling, and monitoring events?
