1. BGP and OSPF are examples of which type of protocol?
- network communication
- network security
- routing
- service discovery
Explanation: BGP and OSPF are routing protocols. They enable routers to exchange route information to reach remote networks.
2. Which two protocols are service discovery protocols? (Choose two.)
- DNS
- TCP
- SSH
- DHCP
Explanation: Service discovery protocols, such as DNS and DHCP enable automatic detection of service. DHCP is used to discover services for automatic IP address allocation and DNS for name-to-IP address resolution services.
3. What is the purpose of the sequencing function in network communication?
- to uniquely label transmitted segments of data for proper reassembly by the receiver
- to determine if data is corrupted during transmission
- to ensure data flows at an efficient rate between sender and receiver
- to guarantee delivery of data
Explanation: Sequencing uniquely identifies or labels each transmitted segment with a sequence number that is used by the receiver to reassemble the segments in the proper order.
4. This protocol is responsible for guaranteeing the reliable delivery of information.
- TCP
- IP
- HTTP
- Ethernet
Explanation: Transmission Control Protocol (TCP) manages the conversation between end devices and guarantees the reliable delivery of information.
