Your campus EX9200 core devices are highly oversubscribed on bandwidth and reporting massive dropped packets. To immediately address the issue, you decide to implement shaping on all interfaces.

Which action will accomplish?

A. Apply the input-shape-rate 5G parameter to all interfaces under the [edit class-of service] hierarchy.

B. Define a CoS input traffic control profile with the shape-rate 5G parameter and apply it to all interfaces.

C. Define a CoS output traffic control profile with the shape-rate 5G parameter and apply it to all interfaces.

D. Apply the shape-rate 5G parameter to all interfaces under the [edit class-of service] hierarchy.]

Which two statements are true about 802.1X dynamic filters based on RADUIS attributes? (Choose two.)

A. Filters can be defined on the network management system and deployed using vendor-specific attributes.

B. Filters can be defined on the switch and deployed upon authentication.

C. Filters can be defined on an automation framework and deployed when triggered by an authentication syslog message.

D. Filters can be defined on the authentication server and deployed using vendor-specific attributes.

You are enabling 802.1X authentication on an EX Series device. You are configuring the switch in the

conference room where you will have non-employees with devices that do not support 802.1X

authentication connecting to your network.

You must ensure that these users can connect to your network but are restricted to Internet access only.

What should you do to accomplish this task?

A. You must add a RADIUS account for each user and assign them to the appropriate VLAN.

B. You should ensure that the server-fail failback feature is enabled and users are assigned to the appropriate VLAN.

C. You should assign a guest VLAN to the interfaces and isolate that VLAN to Internet access only.

D. You should configure a server-reject VLAN to the interfaces and isolate that VLAN to Internet access only.

C. LLDP is enabled on all devices by default

D. LLDP operates on layer 2 interfaces

You have certainly implemented the configuration shown in the exhibit. After committing these changes, the community devices connected to AS-1 are not able to communicate with the appropriate community devices connected to AS-2.

What must be done to allow these community devices to communicate?

B. You must configure the ge-0/0/10 interface on AS1 AS THE VPLAN on both switches

C. You must configure an isolation VLAN ID under the VLAN 200 ON both switches

D. You must configure the ge-0/012 interface on both switches as P VLAN trunks
