• Question 664:

  As the network administrator, you need to develop a verification plan for an OSPF network. The OSPF network has several area routers, area border routers (ABRs), and autonomous system boundary routers (ASBRs).

  Which LSA types should you expect ABRs to generate while verifying the OSPF network? (Choose two.)

  A. Type 4
  B. Type 3
  C. Type 2
  D. Type 5
  A. Type 4
  B. Type 3

  ---

  ABRs generate Type 3 and Type 4 LSAs in an OSPF network. ABRs are those routers that exist between two OSPF areas, as shown in the following figure:

  

  Type 3 and Type 4 LSAs are generated by ABRs to be flooded into other areas to and from the backbone area (area 0). Type 3 LSAs, or summary link advertisements, contain the list of networks known by one area. ABRs send Type 3 LSAs to the other OSPF areas in a given AS.

  OSPF ABRs generates Type 4 LSAs to advertise the list of routes that point to an ASBR. These LSAs advertise the location of the ASBR.

  Type 5 LSAs are not generated by an ABR. These LSAs are generated by ASBRs to describe routes redistributed into the area from other autonomous systems.

  Type 2 LSAs are not generated by an ABR. A Type 2 LSA is generated only by the designated router (DR) of a segment to be sent to the other routers that belong to the same area as the DR. A DR is a router that has the highest OSPF priority on a segment. These advertisements are used by the DR to represent the routers that are connected to the network.

  Objective:

  Sub-Objective:

• Question 665:

  Refer to the exhibit.

  

  The IT manager received reports from users about slow application through network x. which action resolves the issue?

  A. Use the variance 2 command to enable load balancing.
  B. Increase the bandwidth from the service provider.
  C. Move the servers into the users subnet.
  D. Upgrade the IOS on router E.
  A. Use the variance 2 command to enable load balancing.

  ---

  A. could potentially fix something... but very rarely. it's good to keep them updated but not because the older IOS's are necessarily slower. B. what would moving them into the same subnet even do? you still have to actually send the data to the server through the network, needlessly complicating things more. C. yeah lemme just ask my service provider for more bandwidth if things are slow. sounds reasonable. i mean, it would maybe be more plausible if we had reason to believe that was the problem but we don't, it appears that it's our own network causing issues.

  D. load balancing is the most likely to actually do something and is something we can control. might as well try this first.

• Question 666:

  You have configured OSPF on your network and enabled route summarization on an area border router (ABR) with the following command:

  Router(config-router)# area 3 range 165.164.8.0 255.255.248.0

  What does the 3 specify in this command?

  A. The ID of the OSPF backbone
  B. The number of networks summarized in the area
  C. The ID of the area about which routes will be summarized
  D. The ID of the area to which the summary route information will be sent
  C. The ID of the area about which routes will be summarized

  ---

  The 3 in the area range command specifies the area that contains the routes that are to be summarized. In OSPF, you can only configure summarization on the border routers. The summaries need to be of routes within a single area. You summarize the routes of an area so that routers in another area do not see the individual networks, just the summary. The correct command syntax is shown below: area number range ip-address mask The number parameter is the number of the area whose networks are being summarized. For example, in the network shown in the graphic below, to summarize the networks within area 2 to 10.1.0.0/16, you would configure router A with the command area 2 range 10.1.0.0 255.255.0.0. This would not affect the routing tables of the routers within area 2, but instead make the routing tables of areas 0 and 1 smaller. These other routers would only have the summary route listed instead of the individual

  networks. Router C would only see the summary route 10.1.0.0/16.

  

  Objective:

  Layer 3 Technologies

  Sub-Objective:

  Configure and verify manual and autosummarization with any routing protocol

  In order to connect between disparate OSPF and EIGRP portions of a network, mutual route redistribution has been configured. What are two disadvantages of doing this? (Choose two.)

  A. Prone to routing loops if not done correctly
  B. Differing metrics between the routing protocols could result in sub-optimal routing.

  C. option 160 ip 10.221.10.10
  D. option 117 ip 10.221.10.10

• Question 670:

  Which statements about BGP policy-based routing are true? (Choose two.)

  A. BGP policy-based routing is performed on a router's inbound interface.
  B. A BGP administrator can use policy-based routing to alter the final destination of the packet.
  C. BGP policy-based routing will select the next-hop of the packet based on its source address.
  D. BGP policy-based routing can be used to alter the path selection for a packet in a downstream AS.
  A. BGP policy-based routing is performed on a router's inbound interface.
  C. BGP policy-based routing will select the next-hop of the packet based on its source address.

  ---

  BGP policy-based routing is performed on a router's inbound interface. BGP policy-based routing will select the next-hop of the packet based on its source address. It does this through the use of route maps.

  Below is a partial output of the show run command executed on a router that has a BGP configuration that uses a route map to alter the local preference of a route (172.16.0.0/16) to 90 if it is advertised from the BGP neighbor at 10.5.5.1:

  

  The above output indicates that the local preference for the route to 172.16.0.0/16 is 90 ONLY if it comes from 10.5.5.1, but not if the same route is advertised from 10.5.5.35.

  Route maps can be used to influence a part of the routing table without affecting the rest of the table. Consider an example where a router had two routes to every network in the table, and it prefers Neighbor A as the next hop for all routes. If you desired to change the next hop for one of the routes to Neighbor B without affecting the others, you could use route maps to take two different approaches, altering different attributes, which would arrive at the same result. The approaches would be:

  Apply a route map to Neighbor B incoming that would set the local preference to 200 (default is 100) for the route. Local preference values determine the path used to exit the AS. A higher value is preferred. Apply a route map to Neighbor A such that it advertises the route with a MED of 200. Med values determine the preferred path into the AS. A lower value is preferred. The default is 0.

  Either of these approaches would result in the next hop for the network hanging to Neighbor B without affecting the others,

  Policy-based routing does not alter the destination address of the packet. It can only alter the path to that final destination.

  The BGP routing policy in one AS cannot determine the BGP routing policy in another AS.
