A company has workloads that run in a VPC. The workloads access Amazon S3 by using an S3 gateway endpoint. The company also has on-premises workloads that need to access Amazon
S3 privately over a VPN connection. The company has established the VPN connection to the VPC.
Which solution will provide connectivity to Amazon S3 from the VPC workloads and the on-premises workloads in the MOST operationally efficient way?
An organization launched an IPv6-only web portal to support IPv6-native mobile clients. Front-end instances launch in an Amazon VPC associated with an appropriate IPv6 CIDR. The VPC IPv4 CIDR is fully utilized. A single subnet exists in each of two Availability Zones with appropriately configured IPv6 CIDR associations. Auto Scaling is properly configured, and no Elastic Load Balancing is used.
Customers say the service is unavailable during peak load times. The network engineer attempts to launch an instance manually and receives the following message: “There are not enough free addresses in subnet ‘subnet-12345677’ to satisfy the requested number of instances.”
What action will resolve the availability problem?
An ecommerce company is hosting a web application on Amazon EC2 instances to handle continuously changing customer demand. The EC2 instances are part of an Auto Scaling group. The company wants to implement a solution to distribute traffic from customers to the EC2 instances. The company must encrypt all traffic at all stages between the customers and the application servers. No decryption at intermediate points is allowed.
Which solution will meet these requirements?
A finance company runs multiple applications on Amazon EC2 instances in two VPCs that are within a single AWS Region. The company uses one VPC for stock trading applications. The company uses the second VPC for financial applications. Both VPCs are connected to a transit gateway that is configured as a multicast router.
In the stock trading VPC, an EC2 instance that has an IP address of 10.128.10.2 sends trading data over a multicast network to the 239.10.10.10 IP address on UDP Port 5102. The company recently launched two new EC2 instances in the financial application VPC. The new EC2 instances need to receive the multicast stock trading data from the EC2 instance that is in the stock trading VPC.
Which combination of steps should the company take to meet this requirement? (Choose three.)
