Question 96

In the multi-level RR scenario, the first-level RR will be connected to a large number of second-level R, which may cause the BGP circuit of the first-level RR to overflow from the table Risk of R BGP routing table overflow?( Radio).

A.Route Control

B.Set the same Cluster-ID

C.ORF

D.Route Aggregation

Question 97

Regarding the BGP ring protection mechanism, is the following description correct?

A.The Cluster List property is used for loop guard within the reflector cluster, and the router rejects the route when it finds that the Cluster List of the route entry contains its own Cluster ID.

B.You can use the AS_ CONFED_SET attribute to prevent loops within a consortium.

C.Routes learned from IBGP are not advertised to IBGP neighbors and are used to prevent routing loops inside the AS.

D.The AS_ PATH attribute is used between autonomous systems to prevent ring cats

Question 98

When there are multiple redundant links in an IS-IS network, multiple equivalent routes may occur. Regarding equivalent routing within an IS-IS network, which of the following descriptions is wrong?

A.For each of the equivalent routes, you can assign a priority, with the highest priority routes preferred and the rest as backup routes

B.When the number of equivalent routes present in the networking is greater than the number configured by the command, and these routes have the same priority, the next hop device System IlD large routes are preferred for load sharing

C.If load sharing is configured, traffic is evenly distributed across each link

D.After you configure the equivalent routing priority, when the IS-S device forwards traffic to the destination segment, it will not use load sharing, but forward the traffic to the next hop with the highest priority

Question 99

The following is a description of how BFD sessions are established, which is the wrong one

A.Static configuration of BFD session refers to manual configuration of BFD session parameters through the command line, including local identifiers and remote identifiers

B.BFD sessions can only be established dynamically

C.The system distinguishes between static BFD sessions and dynamic BPD sessions by dividing the identifier area Dynamically assign this landmark identifier

Question 100

Which is the correct description of optimal routing election for each protocol in the following options?( Radio).

A.The OSPF protocol puts all the routing information in the LSDB into the IP routing table.

B.From BGP and OSPF, different route entries to reach the same destination segment are learned, and the optimal route is selected to join the IP route table by comparing the protocol's preference value .

C.Route entries in BGP that are unreachable for the next hop are also placed in the IP routing table.
In the

D.BGP protocol, the best route to reach the same destination circumference is selected by comparing the cost values of the route entries.
