Exhibit.
You want to enable redundancy for the EBGP peering between the two routers shown in the exhibit. Which three actions will you perform in this scenario? (Choose three.)
A. Configure loopback interface peering.
B. Configure routes for the peer loopback interface IP addresses.
C. Configure BGP multihop.
D. Configure an MD5 peer authentication.
E. Configure a cluster ID.
正解:A、B、C
解説:
A is correct because you need to configure BGP multihop to enable redundancy for the EBGP peering between the two routers. BGP multihop is a feature that allows BGP peers to establish a session over multiple hops, instead of requiring them to be directly connected1. By default, EBGP peers use a time-to-live (TTL) value of 1 for their packets, which means that they can only reach adjacent neighbors1. However, if you configure BGP multihop with a higher TTL value, you can allow EBGP peers to communicate over multiple routers in between1. This can provide redundancy in case of a link failure or a router failure between the EBGP peers.
B is correct because you need to configure loopback interface peering to enable redundancy for the EBGP peering between the two routers. Loopback interface peering is a technique that uses loopback interfaces as the source and destination addresses for BGP sessions, instead of physical interfaces2. Loopback interfaces are virtual interfaces that are always up andreachable as long as the router is operational2. By using loopback interface peering, you can avoid the dependency on a single physical interface or link for the BGP session, and use multiple paths to reach the loopback address of the peer2. This can provide redundancy and load balancing for the EBGP peering.
C is correct because you need to configure routes for the peer loopback interface IP addresses to enable redundancy for the EBGP peering between the two routers. Routes for the peer loopback interface IP addresses are necessary to ensure that the routers can reach each other's loopback addresses over multiple hops2. You can use static routes or dynamic routing protocols to advertise and learn the routes for the peer loopback interface IP addresses2. Without these routes, the routers will not be able to establish or maintain the BGP session using their loopback interfaces.

You must implement filter-based forwarding. You need to direct traffic from the 192.168.1.0/24 through vr1 and traffic from 10.210.0.128/26 through vr2.
Which configuration is correct in this scenario?
A.
B.
C.
D.
正解:B
質問 # 68
In a LAN segment, which tie-breaker would spanning tree consider if equal-cost paths exist between two or more switches to the root bridge?
A. bridge ID
B. interface number
C. port ID
D. port priority
正解:A
質問 # 69
Which statement is correct about the storm control feature?
A. The storm control feature requires a special license on EX Series switches.
B. The storm control feature is enabled in the factory-default configuration on EX Series switches.
C. The storm control configuration only applies to traffic being sent between the forwarding and control plane.
D. The storm control feature is not supported on aggregate Ethernet interfaces.
正解:B
解説:
The storm control feature is enabled in the factory-default configuration on EX Series switches.
On EX2200, EX3200, EX3300, EX4200, and EX6200 switches, the factory default configuration enables storm control for broadcast and unknown unicast traffic on all switch interfaces. On EX4300 switches, the factory default configuration enables storm control on all Layer 2 switch interfaces.
質問 # 70
Which two statements describe NSR? (Choose two.)
