Which two symptoms would the show processes cpu command be helpful in troubleshooting? (Choose two.

) no link lights failed Telnet sessions to router output queue drops input queue drops excessive collisions The administrator would like to see the commands that are associated with the serial1/0 interface. The administrator enters the command show running-config | section interface serial1/0 but does not receive a response. What could be the problem? The interface is down. The interface does not have any commands associated with it. The interface serial1/0 keyword looks for an exact match and should specify interface Serial1/0. The administrator should have entered the command show run | i interface serial1/0. What does the command show ip interface brief | exclude unassigned display? all interfaces that have an IP address assigned all interfaces that are assigned an access control list the first instance of the unassigned keyword and all lines afterwards only the first section of output that contains the unassigned keyword A router is currently running both OSPF and BGP. The administrator issues the command show ip route | exclude ^B. What routes will be displayed? only OSPF routes only BGP routes both BGP and OSPF routes both OSPF and directly connected routes both BGP and directly connected routes What should be considered when using the debug command? It may result in outdated output. It may render the system unusable. It can be executed from user EXEC. It needs to be used only when the network has heavy traffic.

Refer to the exhibit. What information does this output provide? The router has a connected default route. The router is installing five routes in its routing table. The router received routing updates from The router is advertising its routes to the router with the address

Refer to the exhibit. From the debug ip packet command output, which statement is correct? All packets are the same length. All packets are being process switched. All packets originated within the router. All packets are forwarded out interface FastEthernet0/0. What will occur when the no debug all command is issued? Options for debugging will be displayed. All debugging output will immediately stop. No further debugging information will be generated. General debugging on the router will be disabled, but specific debugging will continue.

Refer to the exhibit. A network administrator used an extended ping to verify connectivity to a remote location. The ping indicated a 50 percent packet loss. What could be the cause of the problem? NAT is filtering the echo reply packets. The packet size is exceeding the MTU. An ACL is blocking the echo reply packets. An ACL is blocking the echo request packets. Load balancing is occurring with packet loss on one path.

Refer to the exhibit. On the basis of the exhibited output, what could be the reason for the failure of the second ping to host The destination network became unreachable after two seconds. The router cannot handle two consecutive extended ping commands. Packets with the DF bit set cannot be transported over a Frame Relay network. An interface of the device along the path to the destination cannot accommodate the large packets.

Refer to the exhibit. A network administrator is testing connectivity to a remote application server. On the basis of the output that is exhibited, what conclusion can be made? A problem exists with Layer 3 connectivity. A connection can be established to all TCP ports on the server. The Open response on R1 indicates that the port (application) is active. A Telnet connection to the HTTP port on a server is unsuccessful. A newly established branch office is reporting connectivity issues with the server farm that is located at the head office. The network administrator suggests that the problem could be with the path MTU. How could the network administrator verify that this is the problem? Escalate the problem to the ISP. Consult the network documentation to determine the MTU. Use the traceroute command to determine where packets are being lost. Send different types of traffic to the destination address to determine which makes it through. Use the extended ping option to send packets of increasing size to the destination to determine the path MTU. A network administrator has received complaints about slow network performance on one segment of a Layer 2 switched network. To determine what types of traffic are on the segment, the administrator decides to configure SPAN to allow the installation of a packet sniffer. Which two items must be configured to allow SPAN to function? (Choose two.) a monitored port or VLAN the threshold value of monitored traffic the port that connects to the packet sniffer the sampling rate of the monitored port or VLAN the dot1q encapsulation on the monitored port By default, Cisco routers send which type of SNMP traps? SNMP version 1 SNMP version 2c SNMP version 3 SNMP versions 1 and 2c SNMP versions 1, 2c, and 3

Refer to the exhibit. The RSPAN configuration for each switch is shown. The network administrator has configured RSPAN to allow the monitoring of traffic to a corporate server. Unfortunately, the administrator is unable to sniff any traffic from the link. Why is the administrator unable to sniff traffic? Only VLAN 1 can be used as the RSPAN VLAN. The session numbers on the two switches do not match. The remote interface on SW1 should be identified as fa0/3. The source and destination interfaces are reversed on SW2. VLAN 100 has not been properly configured as an RSPAN VLAN. What is the effect of the snmp-server ifindex persist command? All SNMP messages will remain in memory until the next interface reset. The SNMP community string index will be encrypted and stored in NVRAM. The SNMP interfaces for all devices in the community will be synchronized in NVRAM. The SNMP interface index for each interface will stay the same, even if the device is rebooted. Which SNMP version offers enhanced security through encryption and authentication? SNMP version 2 SNMP version 2c SNMP version 3 SNMP version 3c SNMP version 5 SNMP version 9 What statistical information is gathered using NetFlow? interface error statistics IP traffic statistics router CPU usage statistics switch memory usage statistics

Refer to the the exhibit. Given the partial NetFlow configuration, which command sequence is required to forward the traffic statistics of interfaces Fa0/0 and Fa0/1 to the NetFlow traffic collector? R1(config)# interface FastEthernet1/0 R1(config-if)# ip flow egress R1(config-if)# exit R1(config)# interface FastEthernet1/0 R1(config-if)# ip flow ingress R1(config-if)# exit R1(config)# ip flow-control source Fa0/0 R1(config)# ip flow-control source Fa0/1 R1(config)# exit R1(config)# ip flow-control source Fa1/0 R1(config)# exit R1(config)# interface FastEthernet0/0 R1(config-if)# ip flow ingress R1(config-if)# exit R1(config)# interface FastEthernet0/1 R1(config-if)# ip flow ingress R1(config-if)# exit Embedded Event Manager events can be triggered based on which three Cisco IOS subsystems? (Choose three.) changes in the CEF table changes in the routing table counter changes execution of a Tcl script SNMP MIB object changes syslog messages
