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?

• A. Configure a scheduler and scheduler map for expedited-forwarding and apply to all interfaces.
• B. Modify the BA classifier to assign code point 101111 to loss priority low.
• C. Remove the BA classifier from all ge-interfaces.
• D. Apply the rate-limit-ef policer to all ge-interfaces.

You are implementing 802.1x access control in your network of EX Series switches. You have some
older client devices connecting to your network which do not support 802.1x.
Which statement is true regarding the older devices?

• A. By default, the supplicant will send EAP messages and keep the port in an unauthorized state.
• B. By default, the authenticator will send EAP messages and keep the port in an unauthorized state. c. By default, the supplicant will send EAP messages until it reaches a predefined limit, after which it begins to forward traffic. By default, the authenticator will send EAP messages until it reaches a predefined, after which it begins to forward traffic.
