   In an MPLS network, what is the primary purpose of label switching?

   • ATo encrypt all data transmitted across the network.
   • BTo provide wireless connectivity between sites.
   • CTo forward packets based on short labels rather than long IP addresses, improving speed and efficiency.
   • DTo replace the need for routing protocols entirely.

   A retail chain operates 50 branch offices that connect to a central data center over an MPLS network. The company is adding a cloud-based inventory application and wants to reduce latency for branch users while keeping MPLS for legacy traffic. The network team wants to avoid manual configuration at each branch. Which approach best meets these requirements?

   • AReplace MPLS with a single broadband connection at each branch and route all traffic over the internet.
   • BExtend the MPLS network to the cloud provider using a virtual router at each branch.
   • CDeploy SD-WAN at each branch with application-aware routing to send cloud traffic over broadband and MPLS traffic over the existing circuit.
   • DConfigure each branch router with static routes to send all traffic to the cloud over MPLS.

   A manufacturing company uses MPLS to connect its plants. The company is experiencing intermittent performance issues with a cloud-based design application. The network team suspects that MPLS is congested during peak hours. The company has a limited budget and cannot upgrade MPLS bandwidth. The design application is not mission-critical but needs better performance. Which solution should the architect implement?

   • AIncrease MPLS bandwidth at the plants experiencing congestion.
   • BRoute all traffic over the internet and decommission MPLS.
   • CDeploy SD-WAN with dynamic path selection to route design application traffic over broadband during peak hours.
   • DImplement QoS on the MPLS routers to prioritize design application traffic.

   A logistics company with 200 branch offices uses MPLS for all connectivity. The company is deploying a real-time tracking application that requires low latency to a public cloud. The budget is fixed, and the company cannot afford to upgrade MPLS bandwidth at all branches. The network team wants to ensure that the tracking application performs well without impacting existing ERP traffic. Which solution should the architect implement?

   • AUse a single VPN tunnel from each branch to the cloud and rely on QoS on the MPLS router.
   • BDeploy SD-WAN with application-aware routing to send tracking traffic over broadband and keep ERP traffic on MPLS.
   • CIncrease MPLS bandwidth at all branches to accommodate the new application.
   • DRoute all traffic, including ERP, over the internet and decommission MPLS.

   Which of the following is a common characteristic of an MPLS VPN?

   • AIt requires a dedicated physical circuit for each site.
   • BIt is primarily used for wireless local area networking.
   • CIt provides a private, isolated network over a service provider's shared infrastructure.
   • DIt provides end-to-end encryption by default.
