Which of the following is a characteristic of distance vector routing?

• Uses link-state databases

• Relies on hop count as the metric

• Utilizes SPF algorithm

• Supports dynamic routing protocols

What is the main disadvantage of distance vector routing?

• Slow convergence

• High memory requirements

• Limited scalability

• Inefficient use of network resources

In distance vector routing, what happens when a link or router fails?

• All routers in the network immediately update their routing tables

• The affected router sends an update to its directly connected neighbors

• The routing protocol floods the network with update messages

• The routing protocol automatically reroutes traffic through alternate paths

Which routing protocol uses distance vector algorithm?

• OSPF (Open Shortest Path First)

• BGP (Border Gateway Protocol)

• RIP (Routing Information Protocol)

• EIGRP (Enhanced Interior Gateway Routing Protocol)

Which of the following is true about FTP?

• It uses TCP as the transport protocol

• It is a connectionless protocol

• It operates on port 80

• It is primarily used for web browsing

Which of the following statements about FTP is correct?

• FTP is a secure protocol that encrypts data during transmission

• FTP allows only one-way transfer of files

• FTP supports both binary and ASCII file transfers

• FTP can only be used to transfer files within a local network

What is the default port number for FTP in active mode?

• 21

• 22

• 23

• 80

Which FTP mode establishes a separate control connection and data connection?

• Active mode

• Passive mode

• Secure mode

• Extended mode

Which of the following is true about SMTP?

• It is a protocol used for web browsing

• It operates on port 80

• It is a protocol used for email transmission

• It is a connectionless protocol

Which of the following is the primary function of SMTP?

• Storing email messages on a server

• Retrieving email messages from a server
