E As shown in the figure, RTB and RTC each learn EBGP route N from RTD, RTB is missing LOCAL_PREF is set to 200, IBGP neighbor relationship is established between RTA, RTB and RTC through loopback, in the RTA routing table, only N, RTB and RTC are The loopback and RTA itself are directly routed. If RTB goes down due to power failure, can route N be switched to RTC immediately on RTA?

A. No, because RTA and RTB establish IBGP neighbor relationship through loopback address. If the interconnection interface is improved, it can be switched up

B. Yes, because the next hop of the route N pointing to RTB is unreachable, RTA immediately switches to RTC

C. Yes, because the neighbor relationship between RTA and RTB is broken, RTA immediately switches to RTC

D. No, because the neighbor relationship between RTA and RTB will not be interrupted until the holdtime expires, and it will take about 3 minutes to switch over.

In the network shown in the figure, the BGP route learning among the routers is normal, and the BGP route attributes are all set to default values.

A. RTA

B. RTD

C. RTB

D. RTC

The networking is as shown in the figure, eBGP runs between AS 100, AS 200, and AS 300, and ATM links between RTC and RTA, and RTC and RTB are connected. 2M line as backup, how to implement it on RTC?

A. Adjust the BGP LP attribute on RTC, set the LP of the route learned from RTA to 100, and set the LP of the route learned from RTB to 200

B. No need to adjust BGP properties, RTC will automatically select the path with high bandwidth

C. RTC filters all BGP routes learned from RTA and accesses AS 100 through AS 200

D. RTC filters the MED attribute from BGP, the MED of the route learned from RTA is set to 200, and the MED of the route learned from RTB is set to 100

GB0-381-ENU 문제 195

The following functions of the convergence layer are ______. (Choose one or more)

A. Access security control

B. Possess a large number of interfaces for connecting with end user computers

C. High-speed packet switching

D. Complex routing strategy
