What does NAT (Network Address Translation) allow devices on a private network to do?

• Access the Internet while hiding private IP addresses behind a public IP address

• Access the Internet without any IP address

• Access only local network resources

• Use both IPv4 and IPv6 addresses simultaneously

Answer explanation

NAT allows devices on a private network to access the Internet while hiding private IP addresses behind a public IP address.

What is a dual stack in networking?

• Using both IPv4 and IPv6 addresses

• Using multiple public IP addresses

• Using multiple private IP addresses

• Using a single IP address for multiple devices

Answer explanation

A dual stack in networking involves using both IPv4 and IPv6 addresses, allowing devices to communicate over both protocols simultaneously.

What is a socket in networking terms?

• An IP address with a given port

• A type of network cable

• A physical connection point for devices

• A software application for network management

Answer explanation

In networking terms, a socket is represented by an IP address along with a specific port number, allowing communication between devices.

What is the first step the IT department should take to ensure efficient communication and resolve connectivity issues between devices on the network?

• Install appropriate network protocols for efficient data transportation.

• Assign a unique MAC and IP address to each device.

• Monitor the network's performance and security with software tools and firewalls.

• Use network troubleshooting tools such as ping and ARP.

Answer explanation

Assigning a unique MAC and IP address to each device is crucial for efficient communication and resolving connectivity issues on the network.

Which tool can be used to diagnose connectivity issues on a network?

• VLAN

• Firewall

• ARP (Address Resolution Protocol)

• Documentation

Answer explanation

ARP (Address Resolution Protocol) can be used to diagnose connectivity issues on a network by mapping IP addresses to MAC addresses.

What should be done to maintain accurate network documentation?

• Use network troubleshooting tools.

• Assign unique MAC and IP addresses.

• Monitor the network's performance.

• Maintain accurate documentation of assigned MAC and IP addresses.

Answer explanation

Maintain accurate documentation of assigned MAC and IP addresses to ensure accurate network documentation.

Which of the following is NOT a step mentioned for ensuring efficient communication and resolving connectivity issues?

• Segment the network based on traffic needs or organize devices on different VLANs.

• Install appropriate network protocols for efficient data transportation.

• Use network troubleshooting tools such as ping and ARP.

• Increase the bandwidth of the network.

Answer explanation

Increasing the bandwidth of the network is not a step mentioned for ensuring efficient communication and resolving connectivity issues.

What is one of the purposes of segmenting the network based on traffic needs or organizing devices on different VLANs?
