An IoT company collects data from thousands of sensors that are deployed in the Unites States and South Asia. The sensors use a proprietary communication protocol that is built on UDP to send the data to a fleet of Amazon EC2 instances. The instances are in an Auto Scaling group and run behind a Network Load Balancer (NLB). The instances, Auto Scaling group, and NLB are deployed in the us-west-2 Region.
Occasionally, the data from the sensors in South Asia gets lost in transit over the internet and does not reach the EC2 instances.
Which solutions will resolve this issue? (Choose two.)
A global company is designing a hybrid architecture to privately access AWS resources in the us-west-2 Region. The company's existing architecture includes a VPC that uses RFC 1918 IP address space. The VPC is connected to an on-premises data center over AWS Direct Connect Amazon Route 53 provides name resolution within the VPC. Locally managed DNS servers in the data center provide DNS services to the on-premises hosts.
The company has applications in the data center that need to download objects from an Amazon S3 bucket in us-west-2.
Which solution can the company use to access Amazon S3 without using the public IP address space?
A company uses Amazon Route 53 to host a public hosted zone for example.com. A network engineer recently reduced the TTL on several records to 60 seconds. The network engineer wants to assess whether the change has increased the number of queries to Route 53 beyond the expected levels that the company identified before the change. The network engineer must obtain the number of queries that have been made to the example.com public hosted zone.
Which solution will provide this information?
A company recently experienced an IP address exhaustion event in its VPCs. The event affected service capacity. The VPCs hold two or more subnets in different Availability Zones.
A network engineer needs to develop a solution that monitors IP address usage across resources in the VPCs. The company needs to receive notification about possible issues so that the company can act before an incident happens.
Which solution will meet these requirements with the LEAST operational overhead?
