Section 5.1 Demonstrate your acquired knowledge about the troubleshooting methodology This will demonstrate your proficiency for section 4.3 of the Network+ 10-009 objectives. 1 / 25 Which best describes a complete troubleshooting process? Identify, guess, fix, ignore Replace hardware, reboot, escalate Identify, theorize, test, plan, implement, verify, document Diagnose, patch, escalate, close 2 / 25 A device is dropping packets intermittently. What’s an effective first step? Replace the switch Gather logs and question recent changes Assign a static IP Add more VLANs 3 / 25 What should be included when documenting a troubleshooting case? Network diagram only User's last known password Problem, actions taken, outcome, and lessons learned Ticket escalation tree 4 / 25 In troubleshooting, what does “test the theory” aim to accomplish? Rule out unlikely possibilities Confirm the suspected root cause Document symptoms Disable all services 5 / 25 When is it appropriate to escalate an issue? Immediately after it's reported After replacing hardware When the problem exceeds your knowledge or access rights When documentation is complete 6 / 25 Which of the following should be considered when identifying symptoms? VLAN tags IP address assignment Specific error messages and behaviors Ping response time 7 / 25 Which technique involves working from Layer 1 to Layer 7 to find a network issue? Divide and conquer Bottom-to-top OSI approach Recursive resolution Passive monitoring 8 / 25 Why should you avoid jumping to conclusions during troubleshooting? It wastes time It causes more stress It might lead to incorrect fixes and additional downtime It prevents documentation 9 / 25 Which step ensures similar problems don’t happen again? Initial problem identification Establishing a new theory Implementing preventive measures Rebooting the system 10 / 25 A tested solution resolves the issue. What comes next? Close the ticket immediately Escalate the fix Verify functionality and implement any preventive measures Skip documentation 11 / 25 What should be done before implementing a fix in a production environment? Reboot all systems Establish a plan and assess its impact Notify external clients Disable backups 12 / 25 During a network outage, what does "question the obvious" mean? Avoid simple checks to save time Check for power and cable connections Jump to Layer 7 of the OSI model Escalate to senior engineers immediately 13 / 25 A user reports that their Wi-Fi frequently disconnects. What’s the best first step? Replace the access point Ask the user when and where the disconnections occur Run a port scan Reboot their system 14 / 25 Why is documentation important in troubleshooting? To justify budget increases To help with future issues and knowledge sharing To report users To create error logs 15 / 25 Which action is part of verifying full system functionality? Creating a new ticket Ensuring the user can complete normal tasks Restarting the DNS server Installing packet sniffers 16 / 25 Which of the following is most likely to assist in duplicating a network issue? Random testing Running known affected workflows or applications Rebooting the network Reinstalling drivers 17 / 25 What is a critical part of planning a resolution to a network issue? Alerting media Considering the potential impact of the solution Skipping testing Replacing firmware 18 / 25 Why is determining what has changed a useful part of problem identification? It helps justify device replacement It may reveal recent updates or reconfigurations that caused the issue It reduces workload It eliminates the need for user feedback 19 / 25 If a theory is not confirmed after testing, what should the technician do? Ignore the problem Develop a new theory or escalatea new theory or escalate C) Implement a random fix Implement a random fix Restart the device 20 / 25 Which step comes after establishing a theory of probable cause? Document the findings Escalate to a manager Test the theory Close the ticket 21 / 25 What does the "divide and conquer" approach refer to in troubleshooting? Disabling all services at once Testing a midpoint in the OSI model to narrow down the issue Isolating different users Working on all problems simultaneously 22 / 25 You suspect a problem with DNS resolution. Using the OSI model, which approach best applies here? Start at the application layer and work down Begin at Layer 7 and test through Layer 1 Replace the DNS server Jump to physical layer diagnostics 23 / 25 What should you do if multiple problems are discovered during the "identify the problem" stage? Escalate the issue immediately Document and ignore secondary issues Approach each issue individually Replace affected hardware 24 / 25 Why is it important to question users during the initial troubleshooting stage? To assign blame To gather relevant context and symptoms mptoms C) To confirm network baselines 25 / 25 What is the first step in the CompTIA troubleshooting methodology? Establish a theory of probable causeis the first step in the CompTIA troubleshooting methodology? Identify the problem Implement the solution Implement the solution Your score is 0% Restart quiz Return to CompTia N+ 10-009 Objectives
