CompTIA Networking Practice Test #1

Question 1

What address should you use as the default gateway address when manually configuring TCP/IP settings on a PC in a SOHO network?

Accepted Answer

the internal address of the Internet router

Answer

The default gateway is the IP address of the device that a computer uses to send traffic to destinations outside its local network. In a SOHO (Small Office/Home Office) network, this is typically the internal IP address of the router that connects the local network to the Internet. Without a correctly configured default gateway, the PC cannot communicate with devices on other networks, including the Internet.

Question 2

192.168.15.211 is what kind of IP address?

Accepted Answer

a private IPv4 address

Answer

IP addresses in the range 192.168.0.0 to 192.168.255.255 are specifically designated as private IPv4 addresses by RFC 1918. These addresses are used for internal networks and are not routable on the public Internet. This allows multiple organizations to use the same address ranges internally without conflict, conserving public IP addresses.

Question 3

For twisted pair cabling, which connection sets are used?

Accepted Answer

RJ11 and RJ45

Answer

RJ11 and RJ45 are the most common connection sets used for twisted pair cabling. RJ11 connectors are typically used for telephone lines and DSL connections, which utilize a smaller number of twisted pairs. RJ45 connectors are the standard for Ethernet networking, found on network interface cards and switches, and accommodate more twisted pairs for higher data rates.

Question 4

What router setting can you use to restrict access to the router to only the devices you specified in the configuration?

Accepted Answer

MAC filtering

Answer

MAC (Media Access Control) filtering allows an administrator to create a whitelist or blacklist of MAC addresses, permitting or denying network access to specific devices. By configuring a whitelist, only devices with MAC addresses explicitly listed in the router's settings will be able to connect to the network. This provides a basic layer of access control to restrict who can join the network.

Question 5

This type of wireless encryption is usually seen in larger businesses, and each user must log in with their own credentials. What does this technology's name stand for?

Accepted Answer

WPA2-Enterprise

Answer

WPA2-Enterprise is a robust wireless security standard designed for corporate environments. Unlike WPA2-Personal, it uses 802.1X authentication, requiring users to authenticate with individual credentials against a central authentication server (like RADIUS). This provides stronger security, centralized management, and individual accountability, making it suitable for larger businesses with many users.
