A network engineer is designing QoS for a data center that carries storage, voice, and best-effort traffic. The engineer wants to ensure that storage traffic is not dropped during congestion, voice traffic has low latency, and best-effort traffic is treated fairly. What is the most effective approach?

Enable trust mode on all interfaces to trust existing markings.

Classify traffic based on DSCP, mark it, and assign to different queues with appropriate scheduling.

Use a single queue for all traffic and rely on TCP congestion control.

Apply the same policy map to all interfaces.

A network administrator wants to classify traffic based on the application protocol (e.g., HTTP or SQL) for QoS treatment. Which classification method is most appropriate for this task?

Using an ACL that matches on Layer 3 and Layer 4 fields such as IP address and TCP/UDP port

Using the DSCP value already present in the packet

Using the destination MAC address

Using the 802.1p priority bits in the VLAN tag

An administrator is configuring QoS on an OS10 switch. The administrator wants to mark traffic from a specific application with DSCP EF and place it in a strict-priority queue. After configuring the class map and policy map, what is the next step?

Apply the service policy to the appropriate interface.

Verify the configuration using 'show qos statistics'.

Create an ACL to match the application's traffic.

Enable trust DSCP on the interface.

Which field in an IP packet header is commonly used to identify traffic for QoS classification on a Dell PowerSwitch?
