Question 1

Exhibit.

YourNet is learning the 210.210.40.0/24 route from Provider A and Provider B YourNet would like to forward traffic destined to the 210.210.40.0/24 networking using Provider B.

Referring to the exhibit, how would you accomplish this task?

AAdd the well-known no-export community to the routes learned through R2.

BApply an export policy to R1's IBGP peers to set a higher local preference.

CAdd the well-known no-export community to the routes learned through R1.

DApply an export policy to R2's IBGP peers to set a Their local preference.

Answer : D

Question 2

Click the Exhibit button.

You recently 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?

AYou must configure to allow the ge-0/0/1 interface on AS-1 as the inter-switch.

BYou must configure the ge-0/0/10 interface on AS-1 as the inter-switch link.

CYou must configure the ge-0/0/1 interface on both switches the inter-switch links.

DYou must configure an isolation VLAN ID under the vlan-pri vlan on the AS-2 switch.

DYou must configure an isolation VLAN ID under the vlan-pri VLAN on both switches.

DBy default, the authenticator will send EAP messages until it reaches a predefined, after which it begins to forward traffic.

Answer : C

Question 6

Exhibit.

You are implementing CoS for a custom application that is labeling its packets with DSCP code-point 101111. You have applied the configuration shown in the exhibit, but not that while some custom application traffic ingressin on ge-0/0/1 transits the SRX Series device successfully, packets ingressing all other ge-* interfaces are being dropped.

Which action should you take to solve this problem?

AConfigure a scheduler and scheduler map for expedited-forwarding and apply to all interfaces.

BModify the BA classifier to assign code point 101111 to loss priority low.

CRemove the BA classifier from all ge-interfaces.

DApply the rate-limit-ef policer to all ge-interfaces.

Answer : D
