CCNA Practice Certification Exam # 1 – CCNA Exploration: Accessing the WAN (Version 4.0) 1. What are three examples of TCP/IP application layer protocols? (Choose three.) a terminal emulation protocol that supports remote console connections with various network devices a protocol created by IBM that makes it easier for mainframes to connect to remote offices a protocol responsible for transporting electronic mail on TCP/IP networks and the Internet a protocol that controls the rate at which data is sent to another computer a protocol that exchanges network management information between a network device and a management console a protocol that conducts a test of the path through which a packet travels from source to destination 2. Refer to the exhibit. The exhibit shows simplified protocol data units from different OSI model layers. Which three statements are true about the PDUs and the encapsulation process? (Choose three.)

The order in which these PDUs are created during the encapsulation process is 2, 1, 4, 3. 3. What are two characteristics of TCP? (Choose two.) data transport reliability best path determination establishing, maintaining, and terminating virtual circuits encapsulation of packets in a data frame with source and destination MAC addresses best-effort datagram delivery 4.
