You are setting up EX4200 switches in a Virtual Chassis configuration to deliver high availability.

Which two actions would improve availability? (Choose two.)

A. Enable graceful Routing Engine switchover.

B. Set the mastership priority value of all switches to 255.

C. Distribute all uplink ports across the REs.

A router is configured to use standard metrics. The router has a single link to a Level 2 IS- IS neighbor.

What is the maximum metric for that link?

A. 63

B. 254

C. 1023

D. 65534

The exhibit shows that Host-1 and Host-2 are attached to the switch and associated with RVI vlan.1. However, traffic sent from Host-1 to Host-2 is not blocked as expected. Why is this problem occurring?

A. Intra-VLAN traffic cannot blocked by a router-based filter.

B. The Block-Host-2 term does not contain the MAC address of Host-2.

C. The block-host filter is applied in the wrong direction of the vlan.1 interface.

D. Inter-VLAN traffic cannot blocked by a router-based filter.

Which three statements are true regarding BGP peers? (Choose three.)

A. BGP peers can reside in the same AS or different ASs.

B. BGP peers on the same router must all use the same peer AS number.

C. External BGP peers have a default TTL value of 1.

D. External BGP peers will always accept the AS path, origin, and next-hop attributes from their neighbors.

E. Internal BGP routers will propagate IBGP learned routes to other IBGP peers by default.

You manage the network shown in the exhibit. All four switches have the default RSTP settings. The elected root bridge is switch-1. You must ensure that switch-4 always prefers the connection to switch-3 to reach the root bridge.

Which two configurations will accomplish this task? (Choose two.)

{master:0}[edit]

A. user@switch-4# show protocols rstp { interface ge-0/0/3.0 { priority 64; cost 20000; } } {master:0}[edit]

B. user@switch-4# show protocols rstp { interface ge-0/0/3.0 { priority 128; cost 20000; } } {master:0}[edit]

C. user@switch-3# show protocols rstp { interface ge-0/0/2.0 { priority 240; cost 200000; } } {master:0}[edit]

D. user@switch-3# show protocols rstp { interface ge-0/0/2.0 { priority 128; cost 2000; } }

In the exhibit, each IP subnet in the campus environment is associated with a unique VLAN ID. Which action will ensure that Host C will communicate with Host A and Host B?

A. Configure all switch ports connecting to the host devices as access ports associated with a common VLAN.

B. Configure a routed VLAN interface for each VLAN and associate it with its corresponding VLAN.

C. Configure a port-based ACL that permits inter-VLAN routing for all configured VLANs

D. Configure all switch ports connecting to the host devices as trunk ports associated with all VLANs.
