   A data center architect is evaluating the traditional three-tier model for a new high-performance computing (HPC) cluster. The HPC application requires very low latency and high bandwidth for east-west traffic between servers. Which limitation of the traditional multitier architecture is most likely to be a problem?

   • AEast-west traffic must traverse multiple hops through the aggregation and core layers, increasing latency
   • BThe access layer cannot provide basic segmentation for the HPC cluster
   • CThe aggregation layer cannot enforce policies for the HPC cluster
   • DThe core layer is unable to provide high-speed connectivity between distribution blocks

   A media streaming company is experiencing high latency for traffic between two application servers that are connected to different access switches in the same data center. The servers are in the same VLAN. What is the most likely cause of this latency in a traditional multitier architecture?

   • AThe servers are connected to the access layer with a 1 Gbps link
   • BThe aggregation layer is performing deep packet inspection
   • CThe access switches are configured with Spanning Tree Protocol (STP) blocking the direct path
   • DThe traffic is forced to traverse the aggregation and core layers due to the hierarchical design

   What is a scalability benefit of a traditional multitier architecture?

   • AIt reduces the number of required switches to a minimum.
   • BIt guarantees zero packet loss during failures.
   • CIt allows for modular growth by adding devices at each layer.
   • DIt eliminates the need for any network upgrades.

   A company is planning a data center for a new application. The application is expected to grow significantly over the next few years. The network team wants to choose an architecture that is easy to scale by adding more devices without disrupting existing services. Which characteristic of the traditional multitier architecture supports this requirement?

   • AThe access layer provides routing between all devices
   • BThe modular design allows adding new access switches and aggregation blocks as needed
   • CThe core layer is designed to be the single point of policy enforcement
   • DThe architecture requires a full mesh of links between all switches
