A network administrator is configuring CoS on a switch and assigns forwarding classes
shown below: Based on the configuration, which action prioritizes call-signal traffic over
critical traffic?

On SRX Series devices, in which order does CoS process ingress packets?

You just configured an interface as an access port and it is up and passing traffic. However,
you notice that all traffic transiting this interface is being classified as best effort. Which
default BA classifier is causing this behavior?

You notice that an interface receiving traffic from multiple devices with no user-configured
CoS parameters has been assigned the ieee802.1p-default classifier. What is the port type
assigned to this interface?

— Exhibit — Click the Exhibit button. According to the configuration shown in the exhibit,
what percentage of the traffic will be dropped when the queue fill level reaches 65 percent?

You are asked to implement CoS on an EX Series switch. You attempt to configure the
priority for the voice and data queue schedulers to medium-high and medium-low priority,
respectively. However, you notice that the only parameters available for the priority is strict
high and low. Why are strict high and low the only available parameters for configuration?

You are asked to configure a CoS weighted tail drop profile on your EX Series switch that
causes all traffic in the best effort queue to drop when the queue is 90 percent full. Which
configuration will accomplish this request?

You must configure a multifield classifier on ge-1/0/0. This classifier must match only TCP
traffic from port number 79, set the loss priority to high, and classify the traffic as
expedited-forwarding. The inbound traffic has no previous CoS markings. Which
configuration meets these requirements?

You are asked to reconfigure a CoS scheduler to limit the assured forwarding queue to a
maximum of 75 percent of the available bandwidth. The assured forwarding queue uses a
strict high priority queue. Which configuration parameter accomplishes this task?

You are asked to configure an interface policer. You must ensure when the bandwidth limit
and burst size are exceeded, that the packet receives a CoS parameter which increases the
probability that the packet will be dropped if the queues are congested. Which policer action
will accomplish this requirement?
