A user reports that their Windows laptop cannot access the internet, but other devices on the same wired network work fine. You run ipconfig and see the IP address 169.254.12.34 with a subnet mask of 255.255.0.0. What is the most likely cause and the next step?

The firewall is blocking DHCP traffic; temporarily disable the firewall to test.

The laptop failed to obtain an IP address from DHCP; check the network cable and DHCP server availability.

The DNS server is unreachable; run nslookup to verify DNS resolution.

The laptop is using a static IP that is outside the corporate subnet; change it to a valid address.

A user cannot access a remote server at 203.0.113.50. You run `tracert 203.0.113.50` and see the following output: Hop 1: 192.168.1.1 responds, Hop 2: 10.0.0.1 responds, Hop 3: * * * Request timed out, Hop 4: * * * Request timed out, Hop 5: 203.0.113.50 responds. What does this indicate?

The user's default gateway is misconfigured.

The path to the destination is functional; the timeouts are due to routers not responding to ICMP.

The firewall on the destination server is blocking ICMP.

The destination server is down.

A technician is troubleshooting a workstation that cannot access the internet. The workstation has IP address 172.16.20.25 with subnet mask 255.255.255.0 and default gateway 172.16.20.1. The technician pings the gateway successfully but cannot ping 8.8.8.8. What is the most likely cause?

The workstation's subnet mask is incorrect.

The workstation's IP address is a private address that cannot be routed on the internet.

The workstation's DNS settings are incorrect.

The default gateway is not configured to route traffic to the internet.
