Which command is used to display CoS configuration and statistics on a Juniper device?

show ipsec security-associations

A network administrator is configuring CoS on an IPsec tunnel interface. The tunnel carries voice and data traffic. The administrator wants to ensure that voice traffic is always served first, and data traffic is served when there is available bandwidth. The administrator has configured a scheduler map with two queues: voice (strict-priority) and data (best-effort). What is the expected behavior of this configuration?

Voice and data traffic will be transmitted in a round-robin fashion, with voice getting a higher share.

Voice and data traffic will be transmitted based on the transmit-rate configured for each queue.

Voice traffic will always be transmitted before data traffic, and data traffic will be transmitted when the voice queue is empty.

Data traffic will always be transmitted before voice traffic, and voice traffic will be dropped if the queue is full.

In CoS scheduling, what is the purpose of a scheduler?

To determine the order in which packets from different queues are transmitted

To encrypt packets before they are queued

To mark packets with DSCP values

To classify packets into different CoS classes

In an IPsec VPN, what is the impact of CoS on traffic prioritization?

It allows high-priority traffic to be forwarded with lower delay and loss

It ensures all traffic receives the same treatment regardless of priority

It increases the bandwidth of the tunnel for high-priority traffic

It changes the encryption algorithm based on traffic priority

What is the purpose of classification in the context of CoS for IPsec tunnels?

To compress packets to reduce bandwidth usage

To encrypt packets with different keys based on their priority

To identify and categorize traffic entering the IPsec tunnel

To verify the integrity of IPsec packets
