Refer to the exhibit. What statement is true regarding the output shown?    The PAP passwords did not match, so the routers are trying CHAP authentication. 4. Why are serial connections preferred over parallel connections for long transmission lengths?    Parallel connections are subject to clock skew and to crosstalk between wires. 5. Which two statements are true about time-division

1. What will a wireless client transmit to discover the available WLAN networks?   probe request 2. Which function is provided by a wireless access point?   converts data from 802.11 to 802.3 frame encapsulation 3. Why is security so important in wireless networks?   Wireless networks broadcast data over a medium that allows easy access. 4. Refer to the exhibit. When configuring the wireless access point, which setting does the network administrator use to configure the unique identifier that client devices use to distinguish this wireless network from others?   Network Name (SSID) 5. Which access method does a wireless access point use to allow for multiple user connectivity and distributed access?   CSMA/CA 6. What does a wireless access point use to allow WLAN clients to learn which networks are available in a given area?   beacon 7. Which three devices do many wireless routers incorporate? (Choose three.)   gateway for connecting to other network infrastructures   built-in Ethernet

1. Which two layers of the OSI model have the same functions as the TCP/IP model Network Access Layer? (Choose two.) • Network • Transport • Physical • Data Link • Session 2. What is a primary function of the trailer information added by the data link layer encapsulation? • supports error detection • ensures ordered arrival of data • provides delivery to correct destination • identifies the devices on the local network • assists intermediary devices with processing and path selection 3. During the encapsulation process, what occurs at the data link layer? • No address is added. • The logical address is added. • The physical address is added. • The process port number is added. 4. What device is considered an intermediary device? • file server • IP phone • laptop • printer • switch 5.Which layer encapsulates the segment into packets? • physical • data link • network • transport 6. Which statements correctly identify the role of intermediary devices in the network? (Choose three.) • dete

1. Refer to the exhibit. Host B attempts to establish a TCP/IP session with host C. During this attempt, a frame was captured at the FastEthernet interface fa0/1 of the San Francisco router. The packet inside the captured frame has the source IP address 10.10.1.2, and the destination IP address is 10.31.1.20. What is the destination MAC address of the frame at the time of capture? • 0060.7320.D632 • 0060.7320.D631 • 0040.8517.44C3 • 0009.B2E4.EE03 • 0010.C2B4.3421 2. What are three characteristics of CSMA/CD? (Choose three.) • It monitors the media for presence of a data signal. • After detecting a collision, hosts can resume transmission after a random timer has expired. • A jam signal is used to ensure that all hosts are aware that a collision has occurred. • Devices can be configured with a higher transmission priority. • Data is transmitted only when the data signal is present. • It uses a token system to avoid collisions. 3. Refer to the exhibit. The PC, the routing table of which

1 Refer to the exhibit. The network administrator needs to setup Switch1 for remote access from HostA. The show ip interface brief is issued on Router1 and the show interfaces trunk command is issued on the Switch1 to verify the current status.
