CCNA 1 v3.1 Module 2 Review Which types of networks pass a token sequentially to each host? • Token Ring • FDDI 2 What are three ways that bandwidth is commonly measured? • kbps • Mbps • Gbps 3 What are typical features that determine throughput? • network topology • number of users on the network 4 What protocols are commonly part of the application layer of the TCP/IP model? • FTP • DNS • HTTP 5 Which of the following are data link layer encapsulation details? (Choose two.) • • • • Packets are put into frames. Data is packaged into a packet. Data is segmented into segments. Data is converted for Internet travel. • An address is added to identify the directly connected device. 6 What device is used to connect LANs that are geographically separated? • router 7 Which of the following is the Layer 4 PDU? • • • • bit frame packet segment 8 What is important to remember about the data link layer of the OSI model when considering Peer to Peer communication? (Choose three.) • • • • It links data to the transport layer. It encapsulates frames into packets. It provides a service to the network layer. It encapsulates the network layer information into a frame. • Its header contains a physical address which is required to complete the data link functions. • It encodes the data link frame into a pattern of 1s and 0s (bits) for transmission on the medium. 9 Which of the following is true regarding network bandwidth? • • • • Bandwidth is free. Bandwidth has capacity limits. Bandwidth never increases. Bandwidth is not a key factor in analyzing network performance. 10 What is the official name for the address assigned to each network interface card (NIC) by its manufacturer? • MAC address 11 Which physical network topology uses a single backbone cable and connects all hosts directly to this cable? • bus 12 What are the layers of the TCP/IP model? • • • • network internet transport application Nebraska Is Totally Awesome 13 Which OSI and TCP/IP layer appears in both models yet has different functions in each? • application 14 What two topologies are considered logical topologies? • Token-passing • broadcast 15 During the data encapsulation process, how is the data broken down by the transport layer? • segments 16 In what 2 ways would you describe a LAN? • operates within a limited geographical area • connects physically adjacent devices 17 Intranet, extranet and access are considered valid types of _____? • VPNs 18 What physical topology connects all cables to a central point of concentration? • star 19 What is the maximum possible throughput obtained end to end on this network when the user on Lab A communicates with the user on LAB D? • The maximum possible throughput is based on the largest connection, the T3. • The maximum possible throughput is based on the smallest connection, the T1. • There is not enough data to determine the maximum possible throughput. • The maximum possible throughput is the T1 plus T3 speed divided by 2. 20 What is the name of the Layer 1 PDU? • bit 21 Which layer of the TCP/IP model encapsulates TCP segments into packets? • internet 22 Which layer of the TCP/IP model deals with quality-of-service issues such as reliability, flow control, and acknowledgement? • transport 23 What data packaging type is created at the data link layer during the data encapsulation process? • frames 24 From the following list, choose the data packaging type that is created at the data link layer during the data encapsulation process. 1. Segments 2. Bits 3. Packets 4. Data 5. Frames • • • • • • 1-3-5-4–2 2-1-3-5–4 2-4-3-5–1 4-3-1-2–5 4-1-3-5–2 3-5-1-2-4 25
