   A hospital is building a new data center. The network team needs to connect hundreds of IoT medical devices to the network. These devices only need basic connectivity and must be isolated from each other to prevent a compromised device from affecting others. Which layer of the traditional multitier architecture is best suited for this task?

   • AAggregation layer
   • BAccess layer
   • CA separate management network
   • DCore layer

   A company is deploying a new application in its data center. The application servers are connected to access switches. The security team requires that traffic between the web servers and the database servers be inspected by a firewall. In a traditional multitier design, where should the firewall be placed to inspect this traffic?

   • AAt the access layer
   • BOn the servers themselves
   • CAt the aggregation layer
   • DAt the core layer

   A company is designing a three-tier data center. They want to implement a redundant aggregation layer using two switches. The access switches will be dual-homed to both aggregation switches. To prevent loops and ensure fast failover, which protocol should be used between the access and aggregation layers?

   • ALink Aggregation Control Protocol (LACP) on a single aggregation switch
   • BSpanning Tree Protocol (STP) with PortFast
   • CVirtual Router Redundancy Protocol (VRRP)
   • DMC-LAG (Multichassis Link Aggregation)

   Which of the following is a common redundancy mechanism used in multitier architectures to ensure high availability?

   • ADisabling Spanning Tree Protocol to avoid loops.
   • BDeploying redundant links and devices at each layer.
   • CUsing a single high-end switch at each layer.
   • DUsing only static routing to avoid protocol failures.

   What is the primary function of the access layer in a traditional multitier data center architecture?

   • ATo provide high-speed backbone connectivity between distribution layers.
   • BTo enforce security policies and perform load balancing.
   • CTo connect end devices and provide basic switching and segmentation.
   • DTo route traffic between different data centers.
