ENARSI- Advanced OSPF Features Questions + Answers Graded A+

You are a network administrator configuring OSPF and EIGRP in your enterprise. One of your routers is receiving an OSPF route to a subnet through more than one path. One route is a redistributed route coming from a Not-So-Stubby-Area and another is coming directly from an adjacent EIGRP Router. Only the external link cost has been set to feed into the Shortest Path First calculations. Which route type will be the one most likely to enter the routing table? - E2 You are a network administrator configuring OSPF and EIGRP in your enterprise. What causes a router to become designated as an ABR? - Having interfaces in the backbone area and another internal area You are a network administrator configuring OSPF and EIGRP in your enterprise. You have already established a functional area 51 in addition to the backbone area and shared summary routes through it. You have reconfigured your router with the configuration that the connected OSPF area as Totally NSSA. However you are not establishing adjacency with the peer ABR. What is a likely reason this is the case? - The ABR has not configured the area as Totally NSSA You are a network administrator configuring OSPF and EIGRP in your enterprise. You would like to designate a non-backbone area of the network so that it can pass type 3 summary LSAs into the stub area but not redistributed routes in the form of type 5 external LSAs. What type of area will achieve this goal? - Stub area You are a network administrator configuring OSPF and EIGRP in your enterprise. You would like to designate a non-backbone area of the network so that it will block type 3 and type 5 LSAs while still allowing for an ASBR in the area to support EIGRP connections. What type of area will achieve this goal? - Totally NSSA You are a network administrator configuring OSPF on routers in your enterprise. You have different types networks that OSPF must span. What network types will use a Designated Router for centralizing route distribution? - Broadcast NBMA You are a network administrator managing OSPF in your enterprise. You want to make the Ethernet interfaces between two directly connected routers more efficient from an OSPF perspective. Whatcommand will convert the interfaces from their default to a more efficient configuration? - (config-if) ip ospf network point-to-point You are a network administrator that has implemented OSPF on the routers in your enterprise. What advantage would adding authentication to OSPF peerings provide you? - Adds defense in depth You are a network administrator that has implemented OSPF on the routers in your enterprise. What commands will secure an interface to use MD5 authentication for OSPF traffic using the OSPF password key of "cisco123"? - ip ospf authentication message-digest ip ospf message-digest-key 1 md5 cisco123 You are a network administrator who would like to use the routing protocol of OSPFv3 for both IPv4 and IPv6 routing. How can you assign interface gig0/1 with an IP address of 192.1.1.1/24 to OSPF process 1 area 0 using OSPFv3? - (config-if) ospfv3 1 ipv4 area 0 You are a network administrator who would like to use the routing protocol of OSPFv3. What most accurately describes the process configuration used to implement the simplest configuration of OSPFv3 for both IPv4 and IPv6 routing? - One router statement with one process
