A network technician is evaluating the desirable features of both access and distribution layer switches. Which two features are common to switches at these two layers? (Choose two.)
- QoS
- PoE
- connectivity to the data center
- link aggregation
- application based filtering
Explanation: Because the access layer is the connection point for endpoints, it plays a big role in ensuring the network is protected from malicious attacks. This protection includes making sure that the end users and endpoints connecting to the network are prevented from accessing services for which they are not authorized. Furthermore, the QoS trust boundary and QoS mechanisms are typically enabled on this layer. The primary function of the distribution layer is to aggregate access layer switches in a given building or campus.
