CompTIA Network+ Question C-56

A technician is installing a surveillance system for a home network. The technician is unsure which ports need to be opened to allow remote access to the system. Which of the following should the technician perform?

A. Disable the network based firewall
B. Implicit deny all traffic on network
C. Configure a VLAN on Layer 2 switch
D. Add the system to the DMZ

Correct Answer: D

Explanation:
By putting the system in the DMZ (demilitarized zone) we increase the security, as the system should be opened for remote access.
A DMZ is a computer host or small network inserted as a “neutral zone” between a company’s private network and the outside public network. It prevents outside users from getting direct access to a server that has company data. A DMZ often contains servers that should be accessible from the public Internet.

CompTIA Network+ Question C-55

A wireless network technician for a local retail store is installing encrypted access points within the store for real-time inventory verification, as well as remote price checking capabilities, while employees are away from the registers. The store is in a fully occupied strip mall that has multiple neighbors allowing guest access to the wireless networks. There are a finite known number of approved handheld devices needing to access the store’s wireless network. Which of the following is the BEST security method to implement on the access points?

A. Port forwarding
B. MAC filtering
C. TLS/TTLS
D. IP ACL

Correct Answer: B

Explanation:
MAC filtering allows traffic to be permitted or denied based on a device’s MAC address. We make a MAC filtering which contains the MAC addresses of all approved devices that need to access the wireless network. This ensures that only approved devices are given access to the network.

CompTIA Network+ Question C-54

A PC technician has installed a new network printer that was preconfigured with the correct static IP address, subnet mask, and default gateway. The printer was installed with a new cable and appears to have link activity, but the printer will not respond to any network communication attempts. Which of the following is MOST likely the cause of the problem?

A. Damaged cable
B. Duplex mismatch
C. Incorrect VLAN assignment
D. Speed mismatch

Correct Answer: C

Explanation:
If a port is accidentally assigned to the wrong VLAN in a switch, it’s as if that client was magically transported to another place in the network. This would explain the inability to communication with the printer, as it is on a different VLAN.
