The statements that are true regarding Aruba NAE agents are A and C.

A. A single NAE script can be used by multiple NAE agents. This means that you can create different instances of the same script with different parameters or settings. For example, you can use the same script to monitor different VLANs or interfaces on the switch1.

C. NAE agents will never consume more than 10% of switch processor resources. This is a built-in safeguard that prevents the agents from affecting the switch performance or stability. If an agent exceeds the 10% limit, it will be automatically disabled and an alert will be generated2.

The other options are incorrect because:

B. NAE agents are not active at all times. They can be enabled or disabled by the user, either manually or based on a schedule. They can also be disabled automatically if they encounter an error or exceed the resource limit1.

D. NAE scripts do not need to be reviewed and signed by Aruba before being used. You can create your own custom scripts using Python and upload them to the switch or Aruba Central. You can also use the scripts provided by Aruba or other sources, as long as they are compatible with the switch firmware version1.

E. A single NAE agent cannot be used by multiple NAE scripts. An agent is an instance of a script that runs on the switch. Each agent can only run one script at a time1.

CoS and DSCP are both methods of marking packets for quality of service (QoS) purposes. QoS is a mechanism that allows network devices to prioritize and differentiate traffic based on certain criteria, such as application type, source, destination, etc. CoS stands for Class of Service and is a 3-bit field in the 802.1Q VLAN tag header. CoS can only be used on Ethernet frames that have a VLAN tag, and it can only be preserved within a single VLAN domain. DSCP stands for Differentiated Services Code Point and is a 6-bit field in the IP header. DSCP can be used on any IP packet, regardless of the underlying layer 2 technology, and it can be preserved throughout the IP packet flow, unless it is modified by intermediate devices. References:

This is because Best Effort traffic is all other kinds of non-detrimental traffic that are not sensitive to Quality of Service metrics (jitter, packet loss, latency). A typical example would be peer-to-peer and email applications2. Background traffic is a type of traffic that is used for system maintenance or backup purposes and does not affect the performance or availability of the network3.

Therefore, Best Effort traffic has a higher priority than Background traffic in terms of network resources allocation and management.
