What is a key benefit of defining a QoS trust boundary?

It increases the bandwidth of the network

It eliminates the need for QoS policies

It allows all devices to set their own QoS markings

It prevents untrusted devices from altering QoS markings

A company wants to prevent end users from modifying the QoS markings on their traffic to gain higher priority. The network team is deciding where to place the trust boundary. Which location is the most appropriate to achieve this goal?

On the router interface facing the core switch.

On the core switch ports facing the distribution switches.

On the distribution switch ports facing the access switches.

On the access switch ports facing the end users.
