87. Refer to the exhibit. An administrator is testing connectivity to a remotedevice with the IP address 10.1.1.1. What does the output of this commandindicate?CCNA 1 Practice Final Answer 007 (v5.02, 2015)Connectivity to the remote device was successful.A router along the path did not have a route to the destination.*A ping packet is being blocked by a security device along the path.The connection timed out while waiting for a reply from the remote device.

88. Which is a function of the show ip route command when used as a tool fortroubleshooting network connectivity? Get answer to your question and much more Answers Explanation & Hints: In order to enter global configuration mode, the command configure terminal , or a shortened version such as config t , must be entered from privileged EXEC mode. In this scenario the
administrator is in user EXEC mode, as indicated by the > symbol after the hostname. The administrator would need to use the enable command to move into privileged EXEC mode before entering the configure terminal command.  Enterprise Networking, Security, and Automation ( Version 7.00) – Modules 1 – 2: OSPF Concepts and Configuration Exam 1. What is a function of OSPF hello packets? to send specifically requested link-state records to discover neighbors and build adjacencies between them to ensure database synchronization between routers to request specific link-state records from neighbor routers 2. Which OPSF packet contains the different types of link-state advertisements? hello DBD LSR LSU LSAck 3. Which three statements describe features of the OSPF topology table? (Choose three.) It is a link-state database that represents the network topology. Its contents are the result of running the SPF algorithm. When converged, all routers in an area have identical topology tables. The topology table contains feasible successor routes. The table can be viewed via the show ip ospf database command. After convergence, the table only contains the lowest cost route entries for all known networks. Explanation: The topology table on an OSPF router is a link-state database (LSDB) that lists information about all other routers in the network, and represents the network topology. All routers within an area have identical link-state databases, and the table can be viewed using the show ip ospf database command. The EIGRP topology table contains feasible successor routes. This concept is not used by OSPF. The SPF algorithm uses the LSDB to produce the unique routing table for each router which contains the lowest cost route entries for known networks. 4. What does an OSPF area contain? routers that share the same router ID routers whose SPF trees are identical routers that have the same link-state information in their LSDBs routers that share the same process ID Explanation: An OSPF area contains one set of link-state information, although each router within the area will process that information individually to form its own SPF tree. OSPF process IDs are locally significant and are created by the administrator. Router IDs uniquely identify each router. 5. What is used to facilitate hierarchical routing in OSPF? the use of multiple areas frequent SPF calculations autosummarization the election of designated routers Explanation: OSPF supports the concept of areas to prevent larger routing tables, excessive SPF calculations, and large LSDBs. Only routers within an area share link-state information. This allows OSPF to scale in a hierarchical fashion with all areas that connect to a backbone area. 6. Which OSPF data structure is identical on all OSPF routers that share the same area? forwarding database link-state database adjacency database routing table Explanation: Regardless of which OSPF area a router resides in, the adjacency database, routing table, and forwarding database are unique for each router. The link-state database lists information about all other routers within an area and is identical across all OSPF routers participating in that area. 7. Which step does an OSPF-enabled router take immediately after establishing an adjacency with another router? builds the topology table exchanges link-state advertisements chooses the best path Which command listed below is used to verify that OSPF is enabled and also provides a list of the networks that are being advertised by the network?The show ip protocols command is a quick way to verify vital OSPF configuration information. This information includes the OSPF process ID, the router ID, networks the router is advertising, the neighbors the router is receiving updates from, and the default administrative distance, which is 110 for OSPF.
Which command is used to verify that OSPF is enabled?Use the ipv6 ospf process-id area area-id [instance instance-id] interface configuration command to enable OSPF for IPv6 on an interface. Table 10-4 explains the parameters of this command.
