Example Questions

Which two data integrity algorithms are commonly used in VPN solutions? (Choose two.) A network administrator needs to configure a serial link between the main office and a remote location. The router at the remote office is a non-Cisco router. How should the network administrator configure the serial interface of the main office router to make the connection? Which three of these statements regarding 802.1Q trunking are correct? (Choose three.) When are packets processed by an inbound access list? A network administrator needs to configure port security on a switch. Which two statements are true? (Choose two.) What are two drawbacks of implementing a link-state routing protocol? (Choose two.) Which command can be used to verify the DLCI destination address in a Frame Relay static configuration? Which protocol provides a method of sharing VLAN configuration information between switches? Which two statements about static NAT translations are true? (Choose two.) Which two statistics appear in show frame-relay map output? (Choose two.) Which routing protocol by default uses bandwidth and delay as metrics? A department decides to replace its hub with a Catalyst 2950 switch that is no longer needed by another department. To prepare the switch for installation, the network administrator has erased the startup configuration and reloaded the switch. However, PCs that are connected to the switch experience various connectivity problems. What is a possible cause of the problem? Which of these represents an IPv6 link-local address? Which of the following describe the process identifier that is used to run OSPF on a router? (Choose two) Which parameter or parameters are used to calculate OSPF cost in Cisco routers? VLAN 3 is not yet configured on your switch. What happens if you set the switchport access vlan 3 command in interface configuration mode? When you are troubleshooting an ACL issue on a router, which command can help you to verify which interfaces are affected by the ACL? Which command is used to display the collection of OSPF link states? Which IPv6 address is the equivalent of the IPv4 interface loopback address 127.0.0.1? Which IPsec security protocol should be used when confidentiality is required? Which command is necessary to permit SSH or Telnet access to a Cisco switch that is otherwise configured for these vty line protocols? What are two characteristics of Frame Relay point-to-point subinterfaces? (Choose two.) Select the action that results from executing these commands. Switch(config-if)# switchport port-security Switch(config-if)# switchport port-security mac-address sticky At which layer of the OSI model is RSTP used to prevent loops? The output of the show frame-relay pvc command shows "PVC STATUS = INACTIVE". What does this mean? A network administrator has configured access list 173 to prevent Telnet and ICMP traffic from reaching a server with the address of 192.168.13.26. Which commands can the administrator issue to verify that the access list is working properly? (Choose three.) A router is running three routing processes: RIP, OSPF, and EIGRP, each configured with default characteristics. Each process learns a route to the same remote network. If there are no static routes to the destination and none of the routes were redistributed, which route will be placed in the IP routing table? Which command helps a network administrator to manage memory by displaying flash memory and NVRAM utilization? A network administrator receives an error message while trying to configure the Ethernet interface of a router with IP address 10.24.24.24/29. Which statement explains the reason for this issue? Which characteristics are representative of a link-state routing protocol? (Choose three) In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN? Workstation A has been assigned an IP address of 192.0.2.24/28. Workstation B has been assigned an IP address of 192.0.2.100/28. The two workstations are connected with a straight- through cable. Attempts to ping between the hosts are unsuccessful. What are two things that could be attempted that would allow communications between the hosts? (Choose two.) Which router command can be used to verify the type of cable connected to interface serial 0/0? What can be done to Frame Relay to resolve split-horizon issues? (Choose two.) A Cisco router that was providing Frame Relay connectivity at a remote site was replaced with a different vendor's frame relay router. Connectivity is now down between the central and remote site. What is the most likely cause of the problem? A company with 25 computers decides to connect its network to the Internet. The company would like for all of the computers to have access to the Internet at the same time, but the company only has four usable public IP addresses. What should be configured on the router so that all computers can connect to the Internet simultaneously? If all OSPF routers in a single area are configured with the same priority value, what value does a router use for the OSPF router ID in the absence of a loopback interface? A switch is configured with all ports assigned to vlan 2 with full duplex FastEthernet to segment existing departmental traffic. What is the effect of adding switch ports to a new VLAN on the switch? A network administrator must configure 200 switch ports to accept traffic from only the currently attached host devices. What would be the most efficient way to configure MAC-level security on all these ports? How does using the service password-encryption command on a router provide additional security? Which form of NAT maps multiple private IP addresses to a single registered IP address by using different ports? You are working in a data center environment and are assigned the address range 10.188.31.0/23. You are asked to develop an IP addressing plan to allow the maximum number of subnets with as many as 30 hosts each. Which IP address range meets these requirements? What does a router do if it has no EIGRP feasible successor route to a destination network and the successor route to that destination network is in active status? You have been asked to come up with a subnet mask that will allow all three web servers to be on the same network while providing the maximum number of subnets. Which network address and subnet mask meet this requirement? Which two privileged mode Cisco IOS commands can be used to determine a Cisco router chassis serial number? (Choose two.) On which options are standard access lists based? Which address is the IPv6 all-RIP-routers multicast group address that is used by RIPng as the destination address for RIP updates? Which two Cisco IOS commands, used in troubleshooting, can enable debug output to a remote location? (Choose two.) Which command is used to enable CHAP authentication, with PAP as the fallback method, on a serial interface? Which two of these statements are true of IPv6 address representation? (Choose two.)
