1. What are two ways that TCP uses the sequence numbers in a segment? (Choose two.) to identify missing segments at the destination to reassemble the segments at the remote location to specify the order in which the segments travel from source to destination to limit the number of segments that can be sentout of an interface at one time to determine if the packet changed during transit 2. Which three statements characterize UDP? (Choose three.) UDP provides connectionless, fast transport of data at Layer 4. UDP provides connection-oriented, fast transport of data at Layer 3. UDP relies on application layer protocols for error detection. UDP works well when an application does not need to guaranteedelivery of data. UDP relies on IP for error detection and recovery. UDP provides sophisticated flow control mechanisms. 3. Refer to the exhibit. Host A sends a data packet to host B. What will be the addressing information of the data packet when it reaches host B? Refer to the exhibit. Host A sends a data packet to host B. What will be the addressing information of the data packet when itreaches host B?
4. Which layer of the OSI model defines logical addressing? application presentation session transport network data link 5. Which device connects a local LAN to a geographically separate network? switch hub router bridge 6. Refer to the exhibit. Router1 receives packets addressed as follows: Source IP address: 192.168.1.88 Destination IP address: 172.16.0.3 Source MAC address:00-11-12-7a-41-10 Destination MAC address: 00-11-5c-cc-a9-c0 Source Port: 1464 Destination Port: 23 Assuming that Router1 has not been configured with NAT, what will happen to the packets?
The packets will be sent to the server because it is a server-based port. The packets will be sent to Switch2 and not leave the switch because the packets are local. The packets will be sent to the laptop host.The packets will be sent to Router1 and dropped because private addresses are not transmitted across the Internet. The packets will be sent to Router2 and dropped because the server is not directly attached. 7. Refer to the exhibit. If host 1 was to send an HTTP request to the web server that connects to Router2, what type of Layer 2 frame would be sent between Router1 and the ISP?
a frame witha header that contains the port number of 80 a frame with a header and trailer, but no MAC addresses a frame with a header and a trailer that only contains IP addresses a frame with the host 1 MAC address as the source and Router1 MAC address as the destination a frame with the host 1 MAC address as the source and the server MAC address as the destination 8. A company needs to connect an officerouter to a service provider to access a WAN. What device is needed to connect the router to the ISP if the service provider supplies a T1 line for the connection? a CSU/DSU a cable modem a DSL router a DTE device an SLA device 9. Refer to the exhibit. A technician applies the configuration in the exhibit to an unconfigured router. To verify the configuration, the technician issues the showrunning-config command in the CLI session with the router. What lines should the technician expect to see in the router output from the show running-config command?
enable password class line console 0 password ccna enable secret cisco enable password class line console 0 password ccna enable secret 5 $1$v0/3$QyQWmJyT7zCa/yaBRasJm0 enable password class line console 0 password ccna enable secret ciscoenable password 7 14141E0A1F17 line console 0 password 7 020507550A enable secret 5 $1$v0/3$QyQWmJyT7zCa/yaBRasJm0 enable password 7 14141E0A1F17 line console 0 password 7 020507550A 10. Refer to the exhibit. If host A sends an IP packet to host B, what will the destination address be in the frame when it leaves host A?
