D413 Telecom and Wireless Communications - Set 2 - Part 2

Correct Answer: Automatic Private IP Addressing, assigns an IP address when DHCP fails

APIPA is a feature that assigns a local IP address from a reserved range when a DHCP server cannot be reached, allowing basic network communication.

Correct Answer: Centralized management and monitoring of network devices

SNMP allows network administrators to manage and monitor network devices such as switches, routers, and servers from a central location.

Correct Answer: To encrypt data transmitted between a web server and a client

SSL certificates provide encryption to secure communication between a client (e.g., a web browser) and a server, protecting sensitive information like passwords.

Correct Answer: Switch

A switch operates at Layer 2 of the OSI model and creates separate collision domains for each connected device, improving network efficiency and reducing data collisions.

Correct Answer: AES encryption

WPA2 uses Advanced Encryption Standard, a more secure encryption method compared to WEP, to protect wireless network communications.

Correct Answer: FTP

File Transfer Protocol is commonly used to transfer large files between computers over a network.

Correct Answer: Incremental backup

Incremental backups only save data that has changed since the last backup, making them faster and more efficient than full backups.

Correct Answer: To ensure reliable data transfer between devices

The transport layer is responsible for reliable data transfer, managing error correction, and packet sequencing between devices.

Correct Answer: Multicast address

Multicast addresses allow routers to send packets to multiple specific destinations simultaneously, improving network efficiency in scenarios like video streaming.

Correct Answer: A backup device that is stored and used only when needed

A cold spare is a backup device that is kept in storage and only used when needed to replace a failed component.

Correct Answer: DHCP server

A DHCP server automatically assigns IP addresses to devices on a network, simplifying network management.

Correct Answer: Data encryption and formatting for the application layer

The presentation layer ensures data is properly formatted, encrypted, and compressed before it is passed to the application layer.

Correct Answer: Kerberos

Kerberos is a network authentication protocol that uses tickets and encryption to securely authenticate users on a network.

Correct Answer: ARP

The Address Resolution Protocol is used to resolve IP addresses to MAC addresses, allowing devices to communicate on a local network.

Correct Answer: To filter incoming and outgoing traffic based on predefined rules

A firewall filters network traffic to prevent unauthorized access and protect the network from external threats.

Correct Answer: To detect unauthorized access or malicious activity in a network

An IDS monitors network traffic for suspicious activity, alerting administrators if unauthorized access or attacks are detected.

Correct Answer: Secure Shell

SSH stands for Secure Shell, a protocol used to securely access and manage remote systems over a network.

Correct Answer: The largest size of a data packet that can be transmitted

The MTU is the maximum size of a data packet that can be transmitted over a network, impacting network efficiency and performance.

Correct Answer: To logically segment a network into smaller parts

A VLAN allows a network to be divided into separate segments, improving security and traffic management without requiring physical separation.

Correct Answer: SMTP

Simple Mail Transfer Protocol is used for sending email from a client to an email server and for server-to-server email transmission.
