Only update the changed routes and the new routes

Broadcasts all of the routes periodically

Update all of the routes using multicast address periodically

Only update the changed routes and the new routes

Update routes when BGP peer requests

Which of the following statements is false?

Link types described by a Router-LSA include P2P, P2MP, TransNet, and StubNet.

Each OSPF router uses only one Router-LSA to describe the status of local links in an area.

Link types described by a Router-LSA include P2P, P2MP, TransNet, and StubNet.

A Network-Summary-LSA describes the metric of the route from an ABR to a destination network segment.

Routing information can be exchanged between a backbone area and a non-backbone area but cannot be exchanged between two non-backbone areas.

Which one of the statements describes the relationship between BGP and AS correctly?

BGP is an EGP running between ASs, and IGP runs within an AS such as OSPF,RIP and IS-IS.

BGP only runs between ASs, and cannot run within an AS.

BGP is an EGP running between ASs, and IGP runs within an AS such as OSPF,RIP and IS-IS.

BGP builds up network topology by exchanging link-state information among Ass.

Which type of BGP route will be added to the BGP routing table?

All BGP routes learned from peers

Only the routes learned from IBGP peers

Only the routes learned from EBGP peers

Which statements about the MED attribute are true? (Choose three.)

Based on BGP route selection rules, the MED attribute takes precedence over the AS_Path, Preferred-Value, Local-Preference, and Origin attributes.

By default, BGP compares MED attributes of only the routes from the same AS. If the compare-different-as-med command is configured, BGP can compare the MED attributes of the routes from different ASs.

By default, if the MED value of a BGP route is not specified, the value 0 is used. If the bestroute med-none-as-maximum command is configured, the maximum MED value 4294967295 is used.

Based on BGP route selection rules, the MED attribute takes precedence over the AS_Path, Preferred-Value, Local-Preference, and Origin attributes.

The MED attribute of a BGP route defaults to 100.

By default, BGP compares MED attributes of only the routes from the same AS. If the compare-different-as-med command is configured, BGP can compare the MED attributes of the routes from different ASs.

By default, if the MED value of a BGP route is not specified, the value 0 is used. If the bestroute med-none-as-maximum command is configured, the maximum MED value 4294967295 is used.

Which of the following statements are correct regarding BGP attribute? (Choose two.)

Till now, there are 16 BGP attributes

BGP attribute can be extended to 256 types

Till now, there are 16 BGP attributes

BGP attribute can be extended to 256 types

Well-known discretionary attribute may not be included in each BGP update message, such as Origin attribute

AS_PATH is an Optional Transitive attribute

What is the function of well-known community attribute NO_EXPORT_SUBCONFED in BGP?

Routes received carrying this value cannot be advertised to any EBGP peers

Routes received carrying this value cannot be advertised outside the confederation

Routes received carrying this value cannot be advertised to any BGP peers

Routes received carrying this value cannot be advertised to any EBGP peers

If the peer default-route-advertise command is used to advertise a default BGP route to peers, how will this operation affect the local BGP routing table?

The local BGP routing table will not be affected and no default route will be generated in the local BGP routing table.

An inactive default route will be generated in the local BGP routing table and this route will not be delivered to the IP routing table.

An active default route will be generated in the local BGP routing table and this route will be delivered to the IP routing table.

The local BGP routing table will not be affected and no default route will be generated in the local BGP routing table.

A default route will be generated in the local BGP routing table and whether to deliver this route to the IP routing table depends on route selection results.

Which of the following statements is false?

An AS-external-ISA describes the means to reach an ASBR.

A Router-LSA describes the local link state information of a router.

A Network-ISA describes the link state information of a broadcast network or an NBMA network segment.

A virtual link is a virtual adjacency in the backbone area (Area 0).

An AS-external-ISA describes the means to reach an ASBR.

Which of the following statements about the Reverse Path Forwarding (RPF) mechanism are true? (Choose two.)

A router discards the received multicast packets if the packets fail the RPF check.

The RPF mechanism has two functions: 1. It prevents multicast routing loops; 2. It avoids forwarding redundant multicast data packets.

Multicast RPF does not depend on unicast routing.

All multicast protocols adopt the RPF mechanism.

A router discards the received multicast packets if the packets fail the RPF check.

The RPF mechanism has two functions: 1. It prevents multicast routing loops; 2. It avoids forwarding redundant multicast data packets.

What are the functions of route filtering? (Choose three.)

Avoids sub-optimal routes generated in route importing.

Implements accurate route importing and controls route advertisement.

Avoids sub-optimal routes generated in route importing.

Affects route selection by changing route attributes.

Implements accurate route importing and controls route advertisement.
