Which of the following characters is not allowed while creating a Namespace for a CloudWatch metric?

Your company operates a single AWS account. A common services VPC is deployed to provide shared services, such as network scanning and compliance tools. Each AWS workload uses its own VPC, and each VPC must peer with the common services VPC. You must choose the most efficient and cost effective approach. Which approach should be used to automate the required VPC peering?

You manage a web service that is used by client applications deployed in 300 offices worldwide. The web service architecture is an Elastic Load Balancer (ELB) distributing traffic across four application servers deployed in an Auto Scaling group across two Availability Zones.

The ELB is configured to use round robin, and sticky sessions are disabled. You have configured the NACLs and security groups to allow port 22 from your bastion host, and port 80 from 0.0.0.0/0. The client configuration is managed by each regional IT team.

Upon inspection you find that a large amount of requests from incorrectly configured sites are causing a single application server to degrade. The remainder of the requests are equally distributed across all servers with no negative effects. What should you do to remedy the situation and prevent future occurrences?

Which of the following are possible causes of the connectivity issues? (Choose TWO)
