Which two statements about designing the Data Center Access layer are correct? (Choose two.)
A . Multiport NIC servers should each have their own IP address.
B . Layer 3 connectivity should never be used in the access layer.
C . Layer 2 connectivity is primarily implemented in the access layer.
D . Multiport NIC servers should never be used in the access layer.
E . Layer 2 clustering implementation requires servers to be Layer 2 adjacent.

Answer: CE

Explanation:

User access is primarily layer 2 in nature, layer 2 clustering is possible only in layer 2

Here is the from the Cisco press CCDA certification guide

Defining the DC Access Layer

The data center access layer’s main purpose is to provide Layer 2 and Layer 3 physical port density for various servers in the data center. In addition, data center access layer switches provide high-performance, low-latency switching and can support a mix of oversubscription requirements. Both Layer 2 and Layer 3 access (also called routed access) designs are available, but most data center access layers are built using Layer 2 connectivity. The Layer 2 access design uses VLAN trunks upstream, which allows data center aggregation services to be shared across the same VLAN and across multiple switches. Other advantages of Layer 2 access are support for NIC teaming and server clustering that requires network connections to be Layer 2 adjacent or on the same VLAN with one another.
