- Matching only default routes
- Matching all routes
- Denying only default routes
- Denying all routes
-
The ABR in a Totally Stubby area will not advertise Type-3, Type-4, and Type-5 LSAs into the Totally Stubby area. Instead, the ABR will advertise a default route to the Totally Stubby area enabling packet forwarding to other destinations.
- TRUE
- FALSE
-
Which of the following problems can be solved by IGMP Snooping?
- Receiver hosts support only IGNPv2, but only the SSM model is used on the network.
- A router receives large quantities of IGMP Report messages due to the existence of large number of hosts on the network.
- Broadcasting of multicast data on Layer 2 devices.
- Validity of IGMP Report messages.
-

- Source’s DR
- Receiver router
- Intermediate router
- RP
-
RTA and RTB are interconnected through a FE interface in an OSPF area. Which of the following can be used to configure the link cost between RTA and RTB as 10? (Select 2 answers)
- Use command “ospf cost 10” on the two routers
- Use command “ospf cost 5” on the two routers
- Use command “bandwidth-reference 500” on the two routers to change bandwidth-reference value
- Use command “bandwidth-reference 1000” on the two routers to change bandwidth-reference value
-
Policy-based routing and routing policies implements the forwarding of data packets in different ways: A routing policy mainly controls packet forwarding. According to the routing policy, packets can be forwarded without a routing table; Policy-based routing mainly controls the importing, advertising, and receiving of routing information.
- TRUE
- FALSE
-
Which type of BGP route can 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
- Only optimal routes
-
Which of the following parameters are optional when configuring a BGP peer? (Select 2 answers)
- IP address
- Description
- Password
- AS-number
-
If the default-route-advertise command is used to advertise a default BGP route to peers, how will this operation affect the local BGP routing table?
- An inactive default route will be generated in the local BGP routing table which will not be delivered to the IP routing table.
- An active default route will be generated in the local BGP routing table which will be delivered to the IP routing table.
- The local BGP routing table will not be affected and no default route will be generated.
- A default route will be generated in the local BGP routing table. Whether this route is delivered to the IP routing table depends on route selection results.
-
Which of the following statements about OSPF neighbor state transition are true? (Select 3 answers)
- The neighbor state transitions from “Loading” to “Full” when a LoadingDone event occurs.
- The neighbor state transitions from the “Exstart” to “full” when a Negotiation Done event occurs.
- The neighbor state transitions from the “Exchange” to “Full” when an ExchangeDone event occurs.
- The neighbor state transitions from “Exchange” to “Loading when an ExchangeDone event occurs.
-

- TRUE
- FALSE
-
Which of the following is used to avoid routing loops in BGP?
- Use ORIGIN attribute to record the origin of the route.
- Use AS_PATH attribute to record all AS areas that a route passes.
- Use NEXTJHOP attribute to record next hop path
