Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

HTTPS (Hypertext Transfer Protocol Secure) is used for secure communication over the internet. It combines HTTP with TLS (Transport Layer Security) or SSL (Secure Sockets Layer) to encrypt data before transmission, ensuring privacy and security.

Multiple choice

Which protocol is used for routing data packets in a network, determining the best path for data transmission?

  1. TCP

  2. UDP

  3. IP

  4. RIP
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

RIP (Routing Information Protocol) is used for routing data packets in a network. It is a distance-vector routing protocol that exchanges routing information between routers to determine the best path for data transmission.

Multiple choice

Which protocol is used for discovering and advertising services on a network, allowing devices to find and connect to services?

  1. DNS

  2. DHCP

  3. NTP

  4. Bonjour
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bonjour is a zero-configuration networking protocol that allows devices to discover and advertise services on a network without the need for manual configuration. It uses multicast DNS (mDNS) to broadcast service information, enabling devices to find and connect to services automatically.

Multiple choice

Which protocol is used for synchronizing the time between computers in a network, ensuring accurate timekeeping?

  1. NTP

  2. DNS

  3. DHCP

  4. Bonjour
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

NTP (Network Time Protocol) is used for synchronizing the time between computers in a network. It provides a reliable and accurate time reference, allowing devices to maintain consistent timekeeping.

Multiple choice

Which protocol is used for assigning IP addresses to devices on a network automatically, simplifying network configuration?

  1. DNS

  2. DHCP

  3. NTP

  4. Bonjour
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

DHCP (Dynamic Host Configuration Protocol) is used for assigning IP addresses to devices on a network automatically. It simplifies network configuration by dynamically assigning IP addresses to devices, eliminating the need for manual configuration.

Multiple choice

Which protocol is used for transmitting voice and video data over a network, enabling real-time communication?

  1. RTP

  2. TCP

  3. UDP

  4. HTTP
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

RTP (Real-time Transport Protocol) is used for transmitting voice and video data over a network, enabling real-time communication. It provides a standardized method for delivering real-time data with low latency and jitter.

Multiple choice

  1. Controller Area Network (CAN)

  2. Local Interconnect Network (LIN)

  3. FlexRay

  4. Time-Triggered Protocol (TTP)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Time-Triggered Protocol (TTP) is a deterministic protocol designed for safety-critical applications in automotive networks, providing reliable and predictable communication for systems that require precise timing and fault tolerance.

Multiple choice
