• A.Attach an Elastic IP address to the internet gateway.
• B.Create an internet gateway and attach it to a VPC.
• C.Add an entry to the route table for the subnet that points to an internet gateway.

A company has an application that is deployed 10 two AWS Regions in an active-passive configuration. The application runs on Amazon EC2 instances behind an Application Load Balancer (ALB) in each Region. The instances are in an Amazon EC2 Auto Scaling group in each Region. The application uses an Amazon Route 53 hosted zone (or DNS. A SysOps administrator needs to configure automatic failover to the secondary Region.
What should the SysOps administrator do to meet these requirements?

• A.Configure Route 53 alias records that point to each ALB. Choose a failover routing policy. Set Evaluate Target Health to Yes.
• B.Configure EC2 health checks for the Auto Scaling group. Add a target group to the ALB in the primary Region. Include the EC2 instances in the secondary Region as targets.
• C.Configure Elastic Load Balancing (ELB) health checks for the Auto Scaling group. Add a target group to the ALB in the primary Region. Include the EC2 instances in the secondary Region as targets.
• D.Configure CNAME records that point to each ALB. Choose a failover routing policy. Set Evaluate Target Health to Yes.

A company is using Amazon CloudFront to serve static content for its web application to its users. The CloudFront distribution uses an existing on-premises website as a custom origin.
The company requires the use of TLS between CloudFront and the origin server. This configuration has worked as expected for several months. However, users are now experiencing HTTP 502 (Bad Gateway) errors when they view webpages that include content from the CloudFront distribution.
What should a SysOps administrator do to resolve this problem?

• A.Examine the expiration date on the certificate on the origin site. Validate that the certificate has not expired. Replace the certificate if necessary.
• B.Examine the hostname on the certificate on the origin site. Validate that the hostname matches one of the hostnames on the CloudFront distribution. Replace the certificate if necessary.
• C.Examine the firewall rules that are associated with the origin server. Validate that port 443 is open for inbound traffic from the internet. Create an inbound rule if necessary.
• D.Examine the network ACL rules that are associated with the CloudFront distribution. Validate that port 443 is open for outbound traffic to the origin server. Create an outbound rule if necessary.

A SysOps administrator needs to configure an Amazon S3 bucket to host a web application. The SysOps administrator has created the S3 bucket and has copied the static files for the web application to the S3 bucket.
The company has a policy that all S3 buckets must not be public.
What should the SysOps administrator do to meet these requirements?

• A.Create an Amazon CloudFront distribution. Configure the S3 bucket as an origin with an origin access identity (OAI). Give the OAI the s3:GetObject permission in the S3 bucket policy.
• B.Create an Application Load Balancer (ALB). Change the protocol to HTTPS in the ALB listener configuration. Forward the traffic to the S3 bucket.
• C.Configure static website hosting in the S3 bucket. Use Amazon Route 53 to create a DNS CNAME to point to the S3 website endpoint.
• D.Create an accelerator in AWS Global Accelerator. Set up a listener configuration for port 443.Set the endpoint type to forward the traffic to the S3 bucket.

A company has an internal web application that runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto Scaling group in a single Availability Zone. A SysOps administrator must make the application highly available.
Which action should the SysOps administrator take to meet this requirement?

• A.Increase the maximum number of instances in the Auto Scaling group to meet the capacity that is required at peak usage.
• B.Increase the minimum number of instances in the Auto Scaling group to meet the capacity that is required at peak usage.
• C.Update the Auto Scaling group to launch new instances in a second Availability Zone in the same AWS Region.
• D.Update the Auto Scaling group to launch new instances in an Availability Zone in a second AWS Region.
