Multiple Choice

The world is currently in a transition to using IPv6, a newer version of the IP protocol that uses 128-bit addresses instead of 32-bit addresses used by IPv4. What is the main problem that IPv6 was created to solve?

• IPv6 will allow problems with IPv4's address hierarchy to be resolved
• 32-bit addresses could not ensure that every internet-connected device can receive a unique IP address
• 32-bit addresses could not accommodate the increased size and amount of data traveling on the Internet as it has grown in popularity
• IPv4 proved unreliable in some cases where network redundancy could not be ensured

Multiple Choice

What is a Wide Area Network (WAN)?

• A network that covers a larger geographic area than a LAN

• A network connecting several campuses within a city

• A network that spans a larger geographical area

Multiple Choice

What is a major advantage of using a LAN?

• Easy global connectivity

• Large geographical coverage

• High data transfer speed at low cost

• Requires no setup

Multiple Choice

How does a switch differ from a hub in a network?

• A switch broadcasts data to all connected devices creating a single collision domain.

• A hub forwards data based on MAC addresses and creates separate collision domains.

• A switch and a hub both create separate collision domains in a network.

• A switch forwards data based on MAC addresses and creates separate collision domains, while a hub broadcasts data to all connected devices creating a single collision domain.

Multiple Choice

What are the characteristics of a Stateless/Packet Filtering Firewall?

• Stateless, efficient, limited complexity

• Stateful, context-aware

• Monitors active connections

• Allows all traffic

Multiple Choice

Which of the following best describes the function of a Next-Generation Firewall (NGFW)?

• It filters traffic based on state, port, and protocol.

• It enhances security by integrating intrusion prevention, deep packet inspection, and application awareness.

• It primarily focuses on filtering traffic based on IP addresses and ports.

• It is designed to protect against physical intrusions into the network.

Multiple Select

Which of the following are downsides of a bus topology (select all that apply)?

• If two (or more) devices try to transmit at the same time, it will cause a collision.

• Every device attached to the bus can "read" every message.

• A failure of the main bus cable will bring the whole network to a stop.

• If there is a failure in the cable that connects a single device to the bus, it will affect just that device.

Multiple Choice

What is the purpose of a port number in networking?

• To identify a specific process

• To connect devices
