Network+ V9 Troubleshooting Methodology Quiz

1. When should you escalate a network troubleshooting issue?

Only if the user demands it

When your troubleshooting steps are exhausted or the issue is beyond your scope

Immediately after identifying the problem

Never; always resolve it yourself

Submit

3. When troubleshooting a connectivity issue, you should always assume the problem is hardware-related. True or False?

True

False

4. The netstat command displays active network connections and listening ports. True or False?

True

False

5. Which of the following is NOT part of the standard troubleshooting methodology?

Identify the problem

Change multiple settings at once to find the cause

Establish a theory of probable cause

Verify full system functionality

6. A ping to a remote host succeeds, but tracert shows timeouts at hop 5. This suggests:

The destination host is offline

A router or firewall is blocking ICMP at that hop

The network cable is damaged

The local gateway is misconfigured

7. What is the purpose of documenting the troubleshooting process?

Only for compliance requirements

To create a knowledge base for future reference and similar issues

To prove the user was wrong

To avoid repeating the same steps

8. Which step requires you to ask 'Is the problem still occurring?' to verify the solution?

Identify the problem

Establish a plan of action

Verify full system functionality and implement preventive measures

Test the theory to determine cause

9. A client receives an APIPA address (169.254.x.x). What does this indicate?

The client is on a different subnet

The DHCP server is unreachable

The router is misconfigured

The DNS server is down

10. Which command resolves a hostname to an IP address?

Nslookup or dig

Arp -a

Route print

Netstat -n

11. Which step of the troubleshooting methodology involves gathering information about the problem from the user or system logs?

Identify the problem

Establish a theory of probable cause

Test the theory to determine cause

Establish a plan of action

12. The arp -a command is used to troubleshoot issues at which OSI layer?

Layer 3 (Network)

Layer 2 (Data Link)

Layer 4 (Transport)

Layer 7 (Application)

13. A host cannot reach a server on a different subnet. Which is a likely cause?

Incorrect default gateway configuration

A bad network cable

DNS server is down

The host's MAC address is invalid

14. What command displays the routing table on a Windows or Linux system?

Ipconfig

Route print or route -n

Netstat -a

Arp -a

15. When implementing a solution, what must you do before making changes in production?

Notify all users immediately

Test in a lab or non-critical environment first

Document only after the fix is applied

Obtain approval from the user only

16. The tracert (or traceroute) command is used to identify which network component?

DNS server failures

The path packets take through routers to a destination

Physical cable damage

DHCP allocation issues

17. A user reports slow network speeds. Which is the best first step in troubleshooting?

Replace the network cable

Question the user to understand the scope and symptoms

Check the router configuration

Restart all network devices

18. Which tool would you use to verify network connectivity at the IP layer?

Nslookup

Ping

Netstat

Tracert

19. What is the primary purpose of the 'establish a plan of action' step?

Immediately apply fixes without testing

Determine potential side effects and outline implementation steps

Document all possible causes

Gather additional information from users

20. When a theory of probable cause cannot be tested, what should you do?

Skip to the next step

Re-examine the problem and establish a new theory

Assume the theory is correct

Document the failure and move on
