Which two options describe Junctions of the data center aggregation layer? (Choose two)

The aggregation layer acts as a services layer where advanced network services such as load balancing, SSL offload, firewalling, and application delivery are applied, consolidating service insertion points for traffic flowing between the access and core layers.

High-speed packet switching with minimal latency is the primary function of the core layer, not the aggregation layer, as the core is optimized purely for forwarding speed.

Access control functions such as routing policies, ACLs, and security zone enforcement are implemented at the aggregation layer to control traffic flows between server pods and the rest of the network.

QoS marking (classifying and tagging traffic) is typically performed at the access layer, closest to the endpoints, so that policy can be enforced consistently throughout the network.
