Technical Terms - Internet (A-Z) - Tunneling

What is the process of transporting network traffic using one protocol within data packets using another protocol?

• Header

• Encapsulation

• Decapsulation

• Encryption

What is the purpose of tunneling in a network?

• To reduce data packet size

• To increase network speed

• To hide the nature of data from other devices

• To block certain protocols

What is the term used for turning an entire data packet into the payload of another data packet using a different protocol?

• Decapsulation

• Encapsulation

• Header

• Encryption

Which of the following is a common use for tunneling?

• Blocking specific websites

• Establishing secure VPN connections

• Reducing network bandwidth

• Increasing network latency

What is the main benefit of using tunneling for VPN connections?

• Limiting network access

• Encrypting all traffic between server and client

• Increasing network congestion

• Decreasing data security

Which tunneling protocol can encrypt traffic for a VPN connection?

• IPsec

• HTTP

• FTP

• SSH

In what scenario would tunneling be used to allow an IPv6 packet to travel over an IPv4 network?

• When the network has no protocol restrictions

• When the network supports both IPv4 and IPv6

• When the network only supports IPv6

• When the network only supports IPv4

What is the purpose of encapsulating restricted traffic within accepted protocols in tunneling?

• To limit network access

• To slow down data transfer

• To increase network security

• To bypass a network's firewall

Which tunneling protocol creates an encrypted SSH tunnel for unencrypted FTP traffic?

• SFTP

• PPTP

• L2TP

• IPsec

What do other devices on the network see when a data packet is encapsulated within another data packet?

• Both header and payload of the encapsulated packet

• Header of the outer packet

• Nothing

• Payload of the encapsulated packet
