Multiple choice

Which network device is responsible for assigning IP addresses to devices on a network?

  1. Switch

  2. Hub

  3. Router

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

A DHCP Server (Dynamic Host Configuration Protocol Server) is responsible for assigning IP addresses to devices on a network. It dynamically assigns IP addresses, subnet masks, and other network configuration parameters to devices, ensuring that each device has a unique IP address.

Multiple choice

Which protocol is commonly used for communication between the control plane and data plane in SDN?

  1. OpenFlow

  2. Border Gateway Protocol (BGP)

  3. Transmission Control Protocol (TCP)

  4. Internet Protocol (IP)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

OpenFlow is a widely adopted protocol used for communication between the control plane and data plane in SDN. It enables the control plane to program and manage the behavior of data plane devices.

Multiple choice

Which protocol is responsible for establishing and maintaining a connection between two hosts on a network?

  1. TCP

  2. UDP

  3. HTTP

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

TCP (Transmission Control Protocol) is a connection-oriented protocol that ensures reliable data transmission by establishing a virtual connection between two hosts before sending data.

Multiple choice

Which protocol is used for sending data in short bursts without the need for a connection?

  1. TCP

  2. UDP

  3. HTTP

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

UDP (User Datagram Protocol) is a connectionless protocol that is used for sending data in short bursts. It does not establish a connection before sending data, making it faster but less reliable than TCP.

Multiple choice

Which protocol is the foundation of the internet and allows devices to communicate across different networks?

  1. TCP

  2. UDP

  3. HTTP

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

IP (Internet Protocol) is the foundation of the internet and is responsible for routing data packets between devices on different networks. It provides a unique address (IP address) to each device connected to the internet.

Multiple choice

Which protocol is used for transferring web pages and other resources from a web server to a client's browser?

  1. TCP

  2. UDP

  3. HTTP

  4. DNS
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

HTTP (Hypertext Transfer Protocol) is used for transferring web pages and other resources from a web server to a client's browser. It is a request-response protocol where the client sends a request to the server, and the server responds with the requested resource.

Multiple choice

Which protocol is used for translating domain names into IP addresses?

  1. TCP

  2. UDP

  3. HTTP

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

DNS (Domain Name System) is used for translating domain names into IP addresses. When a user types a domain name in a web browser, DNS resolves the domain name into the corresponding IP address, allowing the browser to connect to the correct web server.
