   A company is designing a network for a new office. The main application is a centralized ERP system hosted at headquarters. The design team is choosing between a single high-capacity link and two lower-capacity links with load balancing. The ERP system is sensitive to latency but not bandwidth-intensive. Which design choice is more appropriate?

   • AA VPN tunnel over the internet to reduce cost.
   • BTwo lower-capacity links with load balancing to increase total throughput.
   • CA single high-capacity link to minimize latency and avoid load-balancing overhead.
   • DTwo links with failover only, not load balancing, to improve reliability.

   A company is expanding its network to include a remote site. The site will run a real-time application that requires low latency. The network team is considering two designs: a direct MPLS link and a site-to-site VPN over the internet. The MPLS link has a fixed latency of 50 ms and a monthly cost of $2,000. The VPN has a variable latency of 40-80 ms and a monthly cost of $500. The application can tolerate up to 70 ms of latency. Which design is more appropriate?

   • AUse the VPN because it is cheaper and often has lower latency.
   • BUse the MPLS link because it provides consistent latency within the requirement.
   • CUse the VPN and implement QoS to reduce latency.
   • DUse both links and route traffic based on current latency.
