PF Q2: Routing Fundamentals IT2101

What is encapsulation in data communication?

• The process of adding information to an existing unit

• The process of formatting data for presentation

• The process of removing headers from a packet

• The process of routing packets to their destination

Which layer of the OSI model corresponds to a Protocol Data Unit (PDU) that is a segment?

• Physical layer

• Application layer

• Data Link layer

• Transport layer

What does the Internet Control Message Protocol (ICMP) primarily handle?

• Error handling and control of data transmission

• Data formatting for applications

• Address resolution for IP addresses

• Routing packets to remote hosts

What is the main function of the Address Resolution Protocol (ARP)?

• To handle errors in packet transmission

• To manage multicast group memberships

• To obtain the physical address from an IP address

• To define a packet addressing scheme

Which of the following is a characteristic of dynamic routes?

• They are used only in small networks

• They are automatically generated by devices

• They are learned through dynamic routing protocols

• They are manually configured by network administrators

What does a routing table contain?

• Information about the application layer protocols

• Information about the data payload of packets

• Information about which router interface to use for sending data

• Information about the physical addresses of devices

What is the purpose of the 'next hop' in a routing table?

• To indicate the final destination of a packet

• To specify the next device to which packets are forwarded

• To identify the source address of the packet

• To define the outbound interface for data packets

Which protocol is used for data transfer across a serial line?

• Frame Relay

• Point-to-Point Protocol (PPP)

• Ethernet

• Asynchronous Transfer Mode (ATM)

What is the main role of a router in a network?

• To encapsulate data for transmission

• To manage application layer protocols

• To forward packets based on routing information

• To format data for presentation

What does the term 'packet delivery' refer to?

• The process of encapsulating data for transmission

• The way a packet is handled by physical networks

• The method of routing packets to their destination

• The format of data payloads in packets
