   • AIncrease the bandwidth of the internet connection
   • BSwitch all traffic to a different application port
   • CReview and correct the configuration of the network device
   • DReboot the application servers

   A network administrator is troubleshooting a performance issue between two cloud regions connected via a private backbone. Users report that the connection is slow. The administrator runs a traceroute from a VM in Region A to a VM in Region B and sees the following output: the first hop is the local gateway, the second hop is a provider edge router, and the third hop shows a significant increase in latency. The administrator also notices that the third hop is in a different geographic region than expected. What is the most likely cause of the high latency?

   • AThe local gateway in Region A is misconfigured.
   • BThe private backbone is experiencing a regional outage.
   • CThe VM in Region B is overloaded and is adding processing delay.
   • DThe traffic is being routed through a suboptimal path that is not using the cloud provider's private backbone.

   What is the purpose of a health check probe configured on a cloud load balancer?

   • ATo distribute traffic evenly based on the server's current load
   • BTo encrypt the traffic between the load balancer and the backend servers

   A company is migrating a legacy on-premises application to the cloud. The application is a monolithic system that requires very low latency between its components. The operations team is considering a microservices architecture in the cloud, but they are concerned about the added network latency between services. Which approach would best minimize the impact of network latency on the application's performance?

   • ADeploy all microservices in the same availability zone and VNet.
   • BImplement a service mesh with mutual TLS for all inter-service communication.
   • CDeploy microservices across multiple regions for high availability.
   • DUse a public load balancer to route traffic between microservices.
