Regarding the availability of this network (Availabilit), which of the following statements are correct?

A.From the beginning of the network to the present, its availability is 99.96%

B.The availability of the network after the expansion is better than before the expansion

C.Before expansion, network availability was 99.91%

D.The availability of the network after the expansion is worse than before the expansion

GB0-381-ENU Exam Question 92

In the network shown in the figure, BGP routing learning between routers is normal, and BGP routing attributes all take default values. After the route 8.0.0.0 is imported into BGP on RTA, if the next hop of route 8.0.0.0 on RTD is to point to RTC, the following adjustment methods are feasible: ______.

A.Set the Local Preference value of the route sent by RTC to RTD to 50

B.Set the Local Preference value of the route sent by RTB to RTD to 200

C.Set the Local Preference value of the route sent by RTC to RTD to 200

D.Set the Local Preference value of the route sent by RTB to RTD to 50

GB0-381-ENU Exam Question 93

Regarding the BGP aggregation function, which of the following statements are correct?

A.BGP manual aggregation can advertise aggregated routes and specific routes at the same time, or select specific routes to generate aggregated routes.

B.Because BGP supports CIDR, BGP automatic aggregation can automatically aggregate the routes that exist in the routing table into natural mask routes.

C.When using BGP manual aggregation, you can use the attribute-polic- parameter to change the attributes of the aggregated route for more flexible control.

D.BGP aggregation is divided into automatic aggregation and manual aggregation.

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, RTA and RTB, RTC establish IBGP neighbor relationship through loopback, RTA routing table, only N, RTB It is directly routed to the loopback of RTC and RTA itself. If RTB goes down due to a power failure, on RTA, can route N be switched to RTC immediately?

A.No, because the neighbor relationship between RTA and RTB cannot be interrupted until the holdtime expires, and it takes about 3 minutes to switch over.

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

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

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