Question 1

What does the tracert (traceroute) command show on a Windows system?

Accepted Answer

The path and latency from source to destination across network hops

The tracert command traces the route packets take from the source to the destination, showing each hop (router) along the path and the latency to each hop.

Question 2

Which wireless encryption protocol is considered the most secure for modern Wi-Fi networks?

Accepted Answer

WPA3

Answer

WPA3 is the most current and secure Wi-Fi encryption standard, providing stronger protections against password attacks and improved encryption compared to WPA2.

Question 3

A user cannot connect to the internet but can ping 127.0.0.1 successfully. What does this indicate?

Accepted Answer

The TCP/IP stack is functioning but there may be a network or DNS issue

Answer

Successfully pinging 127.0.0.1 (loopback address) confirms the local TCP/IP stack is installed and working, suggesting the issue is with the network connection, router, or DNS rather than the local TCP/IP configuration.

Question 4

What is a common symptom of a duplicate IP address conflict on a network?

Accepted Answer

Intermittent loss of network connectivity on the affected devices

Answer

When two devices share the same IP address, both devices experience intermittent connectivity as the network alternates between recognizing one or the other, causing unpredictable network disruptions.

Question 5

Accepted Answer

Provide port-based network access control requiring authentication before granting access

Answer

IEEE 802.1X provides port-based network access control, requiring devices to authenticate (typically via RADIUS) before being granted access to the network.
