D315 Network and Security Foundations - Set 5 - Part 3

Correct Answer: To resolve IP addresses to MAC addresses

ARP maps IP addresses to MAC addresses, allowing devices on a local network to communicate with each other.

Correct Answer: Man-in-the-middle

In a man-in-the-middle attack, the attacker intercepts communication between two parties, potentially altering or stealing sensitive information.

Correct Answer: Mesh

A mesh topology offers the highest redundancy and fault tolerance since every device is connected to every other device, ensuring multiple paths for data transmission.

Correct Answer: Encryption

SSL (Secure Sockets Layer) provides encryption for network communication, ensuring that data is securely transmitted between the client and server.

Correct Answer: Session

The Session layer (Layer 5) is responsible for establishing, maintaining, and terminating communication sessions between devices.

Correct Answer: To send error messages and operational information

ICMP is used to send error messages, such as when a requested service is unavailable or when data cannot reach its destination.

Correct Answer: TCP ensures reliable data delivery, while UDP does not

TCP (Transmission Control Protocol) is connection-oriented and ensures reliable data delivery, while UDP (User Datagram Protocol) is connectionless and does not guarantee delivery.

Correct Answer: HTTP

HTTP (Hypertext Transfer Protocol) uses port 80 for communication between web browsers and web servers.

Correct Answer: To allow multiple devices to share a single public IP address

NAT enables multiple devices on a private network to access the internet using a single public IP address, translating between private and public addresses.

Correct Answer: To detect and trap malicious activity

A honeypot is a decoy system designed to detect and trap attackers, allowing security teams to monitor and analyze malicious activity.
