Example Questions

Which layer in the OSI reference model is responsible for determining the availability of the receiving program and checking to see if enough resources exist for that communication? What can be done to secure the virtual terminal interfaces on a router? (Choose two.) What are the three things that the Netflow uses to consider the traffic to be in a same flow? (Choose three) What is the alternative notation for the IPv6 address B514:82C3:0000:0000:0029:EC7A:0000:EC72? Which command encrypts all plaintext passwords? How is an EUI-64 format interface ID created from a 48-bit MAC address? What will be the result if the following configuration commands are implemented on a Cisco switch? Switch(config-if)# switchport port-security Switch(config-if)# switchport port-security mac-address sticky A router has two Fast Ethernet interfaces and needs to connect to four VLANs in the local network. How can you accomplish this task, using the fewest physical interfaces and without decreasing network performance? 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 protocol is an open standard protocol framework that is commonly used in VPNs to provide secure end-to-end communications? At which layer of the OSI model is RSTP used to prevent loops? Which two benefits are provided by using a hierarchical addressing network addressing scheme? (Choose two.) A network administrator is troubleshooting an EIGRP problem on a router and needs to confirm the IP addresses of the devices with which the router has established adjacency. The retransmit interval and the queue counts for the adjacent routers also need to be checked. What command will display the required information? Why will a switch never learn a broadcast address? In an Ethernet network, under what two scenarios can devices transmit? (Choose two.) Which statement describes the process of dynamically assigning IP addresses by the DHCP server? Which two are features of IPv6? (Choose two.) Which command is used to enable CHAP authentication, with PAP as the fallback method, on a serial interface? What is one benefit of PVST+? An administrator must assign static IP addresses to the servers in a network. For network, the router is assigned the first usable host address while the sales server is given the last usable host address. Which of the following should be entered into the IP properties box for the sales server? If you want to have more than one Telnet session open at the same time, what key- stroke combination would you use? What is the function of the command switchport trunk native vlan 999 on a Cisco Catalyst switch? What command is used to verify the DLCI destination address in a Frame Relay static configuration? Which IPv6 address is the all-router multicast group? Which two benefits are provided by creating VLANs? (Choose two.) A router has learned three possible routes that could be used to reach a destination network. One route is from EIGRP and has a composite metric of 20514560. Another route is from OSPF with a metric of 782. The last is from RIPv2 and has a metric of 4. Which route or routes will the router install in the routing table? Which characteristics are representative of a link-state routing protocol? (Choose three.) VLAN 3 is not yet configured on your switch. What happens if you set the switchport access vlan 3 command in interface configuration mode? Syslog was configured with a level 3 trap. Which 3 types of logs would be generated (choose three) An example of a device that operates on the physical layer is a . Which two commands can be used to verify a trunk link configuration status on a given Cisco switch interface? (Choose two.) What is the first 24 bits in a MAC address called? Which statement about VLAN operation on Cisco Catalyst switches is true? Which subnet mask would be appropriate for a network address range to be subnetted for up to eight LANs, with each LAN containing 5 to 26 hosts? Which of the following statements are true of IPv6 address representation? (Choose two.) What is known as "one-to-nearest" addressing in IPv6? Which mask should you use on point-to-point WAN links in order to reduce the waste of IP addresses? Which command enables RSTP on a switch? Which statement describes VRRP object tracking? Which command is used to display the collection of OSPF link states? Which two statistics appear in show frame-relay map output? (Choose two.) A network engineer wants to allow a temporary entry for a remote user with a specific username and password so that the user can access the entire network over the Internet. Which ACL can be used? Which command displays CPU utilization? Which two of these are characteristics of the 802.1Q protocol? (Choose two.) Assuming the default switch configuration, which VLAN range can be added, modified, and removed on a Cisco switch? Which set of commands is recommended to prevent the use of a hub in the access layer? Which command would you place on the interface of a private network? Which three are the components of SNMP? (Choose three) You are working in a data center environment and are assigned the address range 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? Which command allows you to verify the encapsulation type (CISCO or IETF) for a Frame Relay link?
