   A hospital is designing a network for its new wing. The network must support life-critical monitoring devices that require 99.999% availability. The hospital has a limited budget and cannot afford a fully redundant network. The network team must decide where to invest in redundancy. Which approach best meets the availability requirement within the budget?

   • AInvest in a redundant core with dual routers and dual links to the distribution layer.
   • BRely on the monitoring devices' ability to reconnect to a backup server if the network fails.
   • CUse a single, high-end access switch with internal redundancy for the monitoring devices.
   • DProvide redundant power supplies and uplinks for the access switches that connect the monitoring devices.

   A growing company is designing a new campus network. They expect to add new buildings and users over the next five years. The business wants to minimize the cost of future expansions. Which modular design principle is most important to adopt?

   • AUse a single large chassis switch in the core to handle all future growth.
   • BUse a flat Layer 2 network to simplify adding new switches.
   • COverprovision the initial network with high-capacity links to avoid future upgrades.
   • DDesign a hierarchical network with access, distribution, and core layers.

   Which design technique is most directly associated with providing network resilience through redundancy?

   • ADeploying dual links and devices with a failover protocol such as HSRP or VRRP
   • BPlacing all critical servers on the same access switch for easier management
   • CImplementing a single, high-end core switch to reduce complexity
   • DUsing a single aggregated link with a large bandwidth to handle all traffic
