   While configuring an IOS router for HSRP with a virtual IP of 10.1.1.1, an engineer sees this log message. Jan 1 12:12:12.111 : %HSRP-4-DIFFVIP1: GigabitEthernet0/0 Grp 1 active routers virtual IP address 10.1.1.1 is different to the locally configured address 10.1.1.25 Which configuration change must the engineer make?

   • AChange the HSRP group configuration on the local router to 1.
   • BChange the HSRP virtual address on the local router to 10.1.1.1.
   • CChange the HSRP virtual address on the remote router to 10.1.1.1.
   • DChange the HSRP group configuration on the remote router to 1.

   Show answer

   Answer: B

   Explanation

   Gentlemen, i strongly agree with Goathammer and Amansoor. Here is my thinking to the topic. since we are configuring a NEW member of HSRP> I ASSUME !!!! that router 1 is the active and already in the network forwarding traffic. if i changed the remote ip address to my newly configured 10.1.1.25 then i run the danger of disrupting network forwarding even for a short time. to not cause any CHANGE to the state of the existing network i would opt to change the NEWLY Configured router 10.1.1.25 to the already running one of 10.1.1.1 long story short the message says that members of the group do not agree on the same virtual ip. so it is up to you to change the running router(s) to the new config risking a short downtime due to Role Selection OR to be on the safe side, just change the NEWLY added router to match the existing setup. i hope my explanations or the way i thought about the problem makes sense. thanks all

   An engineer must configure a new loopback interface on a router and advertise the interface as a /24 in OSPF. Which command set accomplishes this task?

   • AR2(config)#interface Loopback0 R2(config-if)#ip address 172.22.2.1 255.255.255.0 R2(config-if)#ip ospf network broadcast R2(config-if)#ip ospf 100 area 0
   • BR2(config)#interface Loopback0 R2(config-if)#ip address 172.22.2.1 255.255.255.0 R2(config-if)#ip ospf network point-to-point R2(config-if)#ip ospf 100 area 0
   • CR2(config)#interface Loopback0 R2(config-if)#ip address 172.22.2.1 255.255.255.0 R2(config-if)#ip ospf network point-to-multipoint R2(config-if)#router ospf 100
   • DR2(config-router)#network 172.22.2.0 0.0.0.255 area 0 R2(config)#interface Loopback0 R2(config-if)#ip address 172.22.2.1 255.255.255.0 R2(config-if)#ip ospf 100 area 0

   Show answer

   Answer: B

   Explanation

   B is correct. When OSPF is running on a given loopback interface, it sees the network type of "LOOPBACK" and it knows that it can not establish an adjacency through that loopback interface with another router so it advertises that loopback as a host route or the only IP address on that logical interface. As Martin explained so nicely you can tell OSPF that it is not a loopback and it is a point-to-point network type, and OSPF says "OK I am going to advertise the interface with its correct mask". In MPLS environment where OSPF is the IGP in the core, and you have configured the loopback interface of the PE router with a /24 mask, you can have some problems, because there is a discrepancy, the loopback’s mask is 24 but OSPF is advertising a mask of /32. There are few solutions to fix this problem, one solution is to reconfigure the mask to be /32, another solution is to configure the loopback interface with “ip ospf network point-to-point”.

   Answer: See figure below

   Explanation

   ANS RLOC, RESOLVER, ITR Map resolver (MR): This is a network device (typically a router) that receives LISP-encapsulated map requests from an ITR and finds the appropriate ETR to answer those requests by consulting the map server.

   Which congestion queuing method on Cisco IOS based routers uses four static queues?

   • Aweighted fair
   • Bcustom
   • Clow latency
   • Dpriority

   Show answer

   Answer: D

   Explanation

   Priority Queuing (PQ)—This type of queuing places traffic into one of four queues. Each queue has a different level of priority, and higher-priority queues must be emptied before packets are emptied from lower-priority queues. This behavior can “starve out” lower- priority traffic.
