Question 1

Which of the following is the primary function of a router in a computer network?

Accepted Answer

To connect different networks and route data packets

Answer

A router's primary function is to connect different networks, such as your home network to the internet, and direct data traffic between them. It examines the destination IP address of data packets and uses routing tables to determine the most efficient path for them to reach their intended recipient. This ensures that information travels correctly across interconnected networks.

Question 2

Which of the following is a common method of securing a wireless network?

Accepted Answer

Configuring MAC address filtering

Answer

MAC address filtering is a security measure where a wireless access point is configured to only allow devices with specific, pre-approved Media Access Control (MAC) addresses to connect to the network. While not foolproof, it adds a layer of security by restricting network access to known and authorized devices. This helps prevent unauthorized devices from joining the network even if they have the correct password.

Question 3

What does "pinging" a network device do?

Accepted Answer

Verifies if the device is reachable on the network

Answer

Pinging a network device sends a small data packet (an ICMP echo request) to a specified IP address. If the device is online and reachable on the network, it sends back a reply (an ICMP echo reply). This process helps diagnose network connectivity issues and confirm whether a host is active and responding.

Question 4

Which of the following protocols is primarily used to securely transmit data over the web?

Accepted Answer

SSL/TLS

Answer

SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are cryptographic protocols designed to provide secure communication over a computer network. They encrypt the data exchanged between a web server and a client (like your browser), protecting sensitive information from eavesdropping and tampering. This is why secure websites use HTTPS, which is HTTP over SSL/TLS.

Question 5

What is the purpose of DNS (Domain Name System)?

Accepted Answer

To convert IP addresses into human-readable domain names

Answer

The Domain Name System (DNS) acts like the internet's phonebook, translating human-friendly domain names (e.g., google.com) into numerical IP addresses (e.g., 172.217.160.142) that computers use to identify each other. This allows users to access websites by typing easy-to-remember names instead of complex IP addresses. Without DNS, navigating the internet would be significantly more difficult.
