What is the primary role of the core layer in a traditional multitier data center architecture?

To connect end devices such as servers and workstations to the network.

To provide high-speed, resilient connectivity between distribution layers and the data center backbone.

To provide default gateway redundancy for servers using VRRP.

To enforce security policies and perform load balancing for applications.

An engineer is troubleshooting a performance issue in a three-tier data center. A user in the access layer is downloading a large file from a server that is connected to a different access switch in the same building. The engineer notices that the traffic is traversing the core layer. What is the most likely reason for this path?

The aggregation layer is configured for Layer 2 only

The core layer is the only place where QoS policies are applied

The two access switches are in different VLANs and require routing at the core

The access switches are configured with a direct link between them

Which of the following is a common function performed at the aggregation layer in a multitier data center?

Performing server load balancing.

Connecting servers directly to the network.

Providing Power over Ethernet to end devices.

Routing traffic between data centers.
