Question 622:
A company hosts its website in the us-east-1 Region. The company is preparing to deploy its website into the eu-central-1 Region. Website visitors who are located in Europe should access the website that is hosted in eu-central-1. All other visitors access the website that is hosted in us-east-1. The company uses Amazon Route 53 to manage the website's DNS records.
Which routing policy should a SysOps administrator apply to the Route 53 record set to meet these requirements?
A. Geolocation routing policy B. Geoproximity routing policy C. Latency routing policy D. Multivalue answer routing policy
A. Geolocation routing policy geolocation "Geolocation routing lets you choose the resources that serve your traffic based on the geographic location of your users, meaning the location that DNS queries originate from. For example, you might want all queries from Europe to be routed to an ELB load balancer in the Frankfurt region." Could be confused with geoproximity - "Geoproximity routing lets Amazon Route 53 route traffic to your resources based on the geographic location of your users and your resources. You can also optionally choose to route more traffic or less to a given resource by specifying a value, known as a bias. A bias expands or shrinks the size of the geographic region from which traffic is routed to a resource" the use case is not needed as per question. https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-policy.html
Question 623:
A company creates a new member account by using AWS Organizations. A SysOps administrator needs to add AWS Business Support to the new account.
Which combination of steps must the SysOps administrator take to meet this requirement? (Select TWO.)
A. Sign in to the new account by using IAM credentials. Change the support plan. B. Sign in to the new account by using root user credentials. Change the support plan. C. Use the AWS Support API to change the support plan. D. Reset the password of the account root user. E. Create an IAM user that has administrator privileges in the new account.
B. Sign in to the new account by using root user credentials. Change the support plan. D. Reset the password of the account root user. B. Sign in to the new account using root user credentials. Change the support plan. The root user has full access to all AWS services and resources in the account, including the ability to modify the support plan. By signing in with the root user credentials, the SysOps administrator can access the AWS Support Center and update the support plan to AWS Business Support. D. Reset the password of the account root user. Before signing in as the root user in the new account, the SysOps administrator should ensure they have the correct password to access the root user account. If they don't have the password, they should reset it to gain access to the account. Note: Option A (Sign in to the new account using IAM credentials and change the support plan) is incorrect because the IAM user may not have the necessary permissions to modify the support plan. The root user is required for this task. Option C (Use the AWS Support API to change the support plan) is incorrect because although AWS Support provides APIs, using the API alone won't fulfill the requirement without having the necessary permissions, which the root user typically possesses. Option E (Create an IAM user with administrator privileges in the new account) is incorrect because while IAM users with administrator privileges have extensive permissions within the account, they don't have access to change the support plan. The root user is required for this task. https://www.salesforcexamdumps.com/soa-c02-dumps.html#:~:text=Show%20Answer-,Question%20%23%2018,-A%20company%20creates

Question 630:
A company's web application is available through an Amazon CloudFront distribution and directly through an internet-facing Application Load Balancer (ALB) A SysOps administrator must make the application accessible only through the CloudFront distribution and not directly through the ALB. The SysOps administrator must make this change without changing the application code.
Which solution will meet these requirements?
A. Modify the ALB type to internal Set the distribution's origin to the internal ALB domain name B. Create a Lambda@Edge function Configure the function to compare a custom header value in the request with a stored password and to forward the request to the origin in case of a match Associate the function with the distribution. C. Replace the ALB with a new internal ALB Set the distribution's origin to the internal ALB domain name Add a custom HTTP header to the origin settings for the distribution In the ALB listener add a rule to forward requests that contain the matching custom header and the header's value Add a default rule to return a fixed response code of 403. D. Add a custom HTTP header to the origin settings for the distribution in the ALB listener add a rule to forward requests that contain the matching custom header and the header's value Add a default rule to return a fixed response code of 403.
D. Add a custom HTTP header to the origin settings for the distribution in the ALB listener add a rule to forward requests that contain the matching custom header and the header's value Add a default rule to return a fixed response code of 403. To make the application accessible only through the CloudFront distribution and not directly through the Application Load Balancer (ALB), you can add a custom HTTP header to the origin settings for the CloudFront distribution. You can then create a rule in the ALB listener to forward requests that contain the matching custom header and its value to the origin. You can also add a default rule to the ALB listener to return a fixed response code of 403 for requests that do not contain the matching custom header. This will allow you to redirect all requests to the CloudFront distribution and block direct access to the application through the ALB. https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/restrict-access-to-load-balancer.html
