   Why should a network designer consider the monitoring capabilities of the network management system (NMS) when designing a network?

   • ABecause the NMS determines the maximum bandwidth of the network
   • BBecause the design must be observable so that the operations team can detect and troubleshoot issues effectively
   • CBecause the NMS is responsible for enforcing security policies
   • DBecause the NMS is the primary path for user traffic

   A government agency is designing a new network that must comply with a security framework requiring strict segmentation between classified and unclassified data. The agency has a limited budget and cannot afford a completely separate physical network. Which design approach best meets the compliance requirement?

   • AUse VLANs to segment the classified and unclassified traffic and rely on ACLs to enforce the separation.
   • BDeploy a separate physical network for the classified data, even though it is more expensive.
   • CUse a firewall to filter traffic between the two networks and log all access attempts.
   • DUse a single network but encrypt the classified traffic with IPsec to protect it.

   Which statement best describes the primary benefit of using a modular network design approach?

   • AIt reduces the need for network monitoring by simplifying the entire network into a single flat structure.
   • BIt eliminates the need for security policies by isolating traffic within each module.
   • CIt allows each functional area to be designed, implemented, and scaled independently, improving manageability and fault isolation.
   • DIt guarantees that no single point of failure exists anywhere in the network.

   What is the primary difference between SAN and NAS from a network design perspective?

   • ASAN typically uses block-level protocols (e.g., Fibre Channel, iSCSI) while NAS uses file-level protocols (e.g., NFS, SMB)
   • BSAN is for backup only while NAS is for primary storage
   • CSAN uses Ethernet exclusively while NAS uses Fibre Channel
   • DSAN requires multicast while NAS requires unicast
