What ports do HTTPS and RDP utilize?

Options are :

  • 443, 25
  • 443, 161
  • 443, 3389 (Correct)
  • 443, 445

You are a network administrator troubleshooting an issue with a newly-installed web server. The web server is available to internal network users, but users from outside the internal network (Internet users) cannot reach the server. You run an IPCONFIG and receive the configuration below:

IP               192.168.0.10
Netmask     255.255.255.0
Gateway     192.168.0.2
DNS            10.10.0.254

What is the MOST LIKELY reason why the server is unreachable from the Internet?

Options are :

  • The configured DNS server is not reachable by the web server.
  • The gateway IP has been configured incorrectly.
  • The Layer 3 switch port connecting the web server is blocking port 80.
  • NAT has not been configured on the border firewall. (Correct)

Answer : NAT has not been configured on the border firewall.

Explanation The most likely cause is that the NAT has not been configured on the border firewall properly. This would cause the internal network users to still be able to access the web servers (since internal traffic doesn't have to transit the firewall), but would still prevent the Internet users from accessing the web server.

You are a network administrator who is testing a cable you found in your network closet. You connect a cable tester to both sides of the cable to verify the pinout of the Ethernet cable. After testing each pin, your cable tester gives you the following output:

Based on this output, what kind of cable did you test?

Options are :

  • Patch cable
  • Crossover cable (Correct)
  • Rollover cable
  • RG-6 cable

Answer : Crossover cable

Explanation This is a crossover cable, as indicated by the reversing of the Tx and Rx pins (pins 1, 2, 3, and 6).

JK0-019 CompTIA E2C Network + Certification Exam Set 3

What is the broadcast address for the 75.119.217.117/28 network?

Options are :

  • 75.119.217.111
  • 75.119.217.112
  • 75.119.217.127 (Correct)
  • 75.119.217.128

Answer : 75.119.217.127

Explanation Since the network is a /28, each subnet is 16 IPs. The first IP is the network and the 16th is the broadcast. That means the broadcasts are located at 15, 31, 47, 63, 79, 95, 111, and 127. Therefore, the broadcast is 75.119.217.127.
