There are two community-filters: ip community-filter I permit 100:1 200:1 ip community-filter 2 permit 100:1 ip community-filter 2 permit 200:1 Which of the following statements are true?

A BGP route matches community-filter I only when the community attributes carried in the route contain both 100:1 and 200:1. A BGP route matches community-filter l as long as the community attributes carried in the route contain100:1 0r 200:1, or both. A BGP route matches community-filter 2 0nly when the community attributes carried in the route containboth 100:1 and 200:1. A BGP route matches community-filter 2 as long as the community attributes carried in the route contain100:1 0r 200:1, or both.

2.

If a BGP peer is configured with multiple route selection tools for route filtering, which of the following statements are true?

The routes received from the BGP peer are matched first with IP-prefix and then with route-policy. The routes received from the BGP peer are matched first with route olicy and then with IP-prefix. The routes sent to the BGP peer are matched first with IP-prefix and then with route-policy. The routes sent to the BGP peer are matched first with route-policy and then with IP-prefix.

3.

What are the common methods of learning routing information?

Importing direct routes Importing static routes Importing routes of some routing protocols, for example, OSPF, IS-IS, and BGP Receiving the route s advertised by peers

4.

What are the functions of route filtering?

Avoids sub-optimal routes generated in route importing. Avoids routing loops. Affects route selection by changing route attributes. Implements accurate route importing and controls route advertisement

5.

Which of the following route selection tools can be used in multiple routing protocols, be configured with matching conditions, and be composed of if-match and apply clauses?

AS-path-filter IP-prefix Route-policy Community-filter

6.

One route-policy may have several nodes and each node has a node ID. Each node may have multiple if-match and apply clauses. Which of the following statements are true?

Different nodes are in an OR relationship. Different nodes are in an AND relationship. IF-match clauses under a node are in an AND relationship. If-match clauses under a node are in an OR relationship.

7.

Which of the following methods are supported by OSPF for delivering default routes?

Delivery by an ABR Delivery by an ASBR Forcible delivery Non-forcible delivery

8.

Which of the following methods can be used to apply policy-based routing?

Apply policy-based routing in the system view. In this case, policy-based routing takes effect on all the packets received by the local router. Apply policy-based routing in the system view. In this case, policy-based routing takes effect only on thepackets originated by the local router. Apply policy-based routing in the interface view. In this case, policy-based routing takes effect on thepackets sent and received by the local interface. Apply policy-based routing in the interface view. In this case, policy-based routing takes effect only on thepackets received by the local interface.

9.

The configurations of the defined route-policy test are as follows:
ip community-filter I permit 100:1
ip AS-path-filter 2 permit 100$
Route-policy test permit node 10
If-match community-filter I
If-match AS-path-filter 2
apply as-path 200 _
Which of the following statements is true?

The BGP routes will match the route-policy test only when they contain either community attribute 100:1 0r as-path 100. The as-path of the matched routes is then changed to 200. The BGP routes will match the route-policy test only when they contain both community attribute 100:1 andas-path 100. The as-path of the matched routes is then changed to 200. The BGP routes will match the route-policy test only when they contain as-path 100. The as-path of thematched
routes is then changed to 200. The BGP routes will match the route-policy test as long as they contain community attribute 100: 1. The as-path of the matched routes is then changed to 200.

10.
