Final Exam v5 Q91-Q105
regenerating data signals applying security settings to control the flow of data notifying other devices when errors occur
A host is accessing a Telnet server on a remote network. Which three functions are performed by intermediary network devices during this conversation? (Choose three.) regenerating data signals acting as a client or a server providing a channel over which messages travel applying security settings to control the flow of data notifying other devices when errors occur serving as the source or destination of the messages
The configuration will load when the router is restarted.
A network administrator is making changes to the configuration of a router. After making the changes and verifying the results, the administrator issues the copy running-config startup-config command. What will happen after this command executes? The configuration will be copied to flash. The configuration will load when the router is restarted. The new configuration file will replace the IOS file. The changes will be lost when the router restarts.
RAM
During normal operation, from which location do most Cisco switches and routers run the IOS? RAM flash NVRAM disk drive
area C
Refer to the exhibit. Which area would most likely be an extranet for the company network that is shown? area A area B area C area D
audio conference, financial transactions, web page
Three office workers are using the corporate network. The first employee uses a web browser to view a company web page in order to read some announcements. The second employee accesses the corporate database to perform some financial transactions. The third employee participates in an important live audio conference with other office workers in branch offices. If QoS is implemented on this network, what will be the priorities from highest to lowest of the different data types? audio conference, financial transactions, web page financial transactions, web page, audio conference audio conference, web page, financial transactions financial transactions, audio conference, web page
adjacency tables forwarding information base (FIB)
What are the two main components of Cisco Express Forwarding (CEF)? (Choose two.) adjacency tables MAC-address tables routing tables ARP tables forwarding information base (FIB)
The switch drops the frame.
What happens when a switch receives a frame and the calculated CRC value is different than the value that is in the FCS field? The switch places the new CRC value in the FCS field and forwards the frame. The switch notifies the source of the bad frame. The switch drops the frame. The switch floods the frame to all ports except the port through which the frame arrived to notify the hosts of the error.
The TCP/IP stack on the device is working correctly.
What information does the loopback test provide? The TCP/IP stack on the device is working correctly. The device has end-to-end connectivity. DHCP is working correctly. The Ethernet cable is working correctly. The device has the correct IP address on the network.
It places information in the frame allowing multiple Layer 3 protocols to use the same network interface and media.
What is a characteristic of the LLC sublayer? It provides the logical addressing required that identifies the device. It provides delimitation of data according to the physical signaling requirements of the medium. It places information in the frame allowing multiple Layer 3 protocols to use the same network interface and media. It defines software processes that provide services to the physical layer
the automatic configuration of an interface for a straight-through or a crossover Ethernet cable connection
What is the auto-MDIX feature on a switch? the automatic configuration of an interface for 10/100/1000 Mb/s operation the automatic configuration of an interface for a straight-through or a crossover Ethernet cable connection the automatic configuration of full-duplex operation over a single Ethernet copper or optical cable the ability to turn a switch interface on or off accordingly if an active connection is detected
to reduce the cost of deploying and maintaining the communication infrastructure
What is the purpose of having a converged network? to provide high speed connectivity to all end devices to make sure that all types of data packets will be treated equally to achieve fault tolerance and high availability of data network infrastructure devices to reduce the cost of deploying and maintaining the communication infrastructure
CSMA/CA
What method is used to manage contention-based access on a wireless network? CSMA/CD priority ordering CSMA/CA token passing
FFFF.FFFF.FFFF
Which destination address is used in an ARP request frame? 0.0.0.0 255.255.255.255 FFFF.FFFF.FFFF 127.0.0.1 01-00-5E-00-AA-23
store-and-forward switching
Which frame forwarding method receives the entire frame and performs a CRC check to detect errors before forwarding the frame? cut-through switching store-and-forward switching fragment-free switching fast-forward switching
It de-encapsulates the packet, selects the appropriate path, and encapsulates the packet to forward it toward the destination host.
Which statement describes the sequence of processes executed by a router when it receives a packet from a host to be delivered to a host on another network? It receives the packet and forwards it directly to the destination host. It de-encapsulates the packet, selects the appropriate path, and encapsulates the packet to forward it toward the destination host. It de-encapsulates the packet and forwards it toward the destination host. It selects the path and forwards it toward the destination host.
