D Correct answer
Explanation

DHCP (Dynamic Host Configuration Protocol) is responsible for assigning IP addresses, subnet masks, and other network configuration parameters to devices on a network automatically.

Multiple choice

Which network protocol is used for transferring files between devices on a network?

  1. TCP

  2. UDP

  3. HTTP

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

FTP (File Transfer Protocol) is a network protocol specifically designed for transferring files between devices on a network, allowing users to upload, download, and manage files remotely.

Multiple choice

What is the purpose of a network mask in an IP address?

  1. To identify the network portion of an IP address

  2. To identify the host portion of an IP address

  3. To provide security to network data

  4. To store network data
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A network mask is used to determine which part of an IP address represents the network address and which part represents the host address, allowing devices to identify the network they belong to.

  2. UDP

  3. HTTP

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

HTTP (Hypertext Transfer Protocol) is a network protocol used for transferring web pages and other resources between devices on a network, allowing users to access and browse the internet.

Multiple choice

What is the purpose of a DNS server in a network?

  1. To connect devices to the network

  2. To forward data packets between networks

  3. To provide security to network data

  4. To translate domain names into IP addresses
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A DNS server is responsible for translating domain names, which are human-readable website addresses, into IP addresses, which are numerical addresses used by devices to communicate on a network.

Multiple choice

Which protocol is used for signaling in UMTS?

  1. GPRS Tunneling Protocol (GTP)

  2. Internet Protocol (IP)

  3. User Datagram Protocol (UDP)

  4. Transmission Control Protocol (TCP)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

GTP is used for signaling in UMTS. It is a tunnel protocol that encapsulates IP packets and sends them over a GPRS network.

Multiple choice
