Demo Questions

Question 1
An Amazon EC2 instance needs to be reachable from the internet. The EC2 instance is in a subnet with the following route table. Which entry must a SysOps administrator add to the route table to meet this requirement?
  1. A route for `0.0.0.0/0` that points to a NAT gateway.
  2. A route for `0.0.0.0/0` that points to an egress-only internet gateway.
  3. A route for `0.0.0.0/0` that points to an internet gateway.
  4. A route for `0.0.0.0/0` that points to an elastic network interface.
Correct answer: C
Question 2
A SysOps administrator launches an Amazon EC2 instance in a private subnet of a VPC. When the SysOps administrator attempts a curl command from the command line of the EC2 instance, the SysOps administrator cannot connect to https:www.example.com. What should the SysOps administrator do to resolve this issue?
  1. Ensure that there is an outbound security group for port `443` to `0.0.0.0/0`.
  2. Ensure that there is an inbound security group for port `443` from `0.0.0.0/0`.
  3. Ensure that there is an outbound network ACL for ephemeral ports `1024-66535` to `0.0.0.0/0`.
  4. Ensure that there is an outbound network ACL for port `80` to `0.0.0.0/0`.
Correct answer: A
Question 3
A company's public website is hosted in an Amazon S3 bucket in the `us-east-1` Region behind an Amazon CloudFront distribution. The company wants to ensure that the website is protected from DDoS attacks. A SysOps administrator needs to deploy a solution that gives the company the ability to maintain control over the rate limit at which DDoS protections are applied. Which solution will meet these requirements?
  1. Deploy a global-scoped AWS WAF web ACL with an allow default action. Configure an AWS WAF rate-based rule to block matching traffic. Associate the web ACL with the CloudFront distribution.
  2. Deploy an AWS WAF web ACL with an allow default action in `us-east-1`. Configure an AWS WAF rate-based rule to block matching traffic. Associate the web ACL with the S3 bucket.
  3. Deploy a global-scoped AWS WAF web ACL with a block default action. Configure an AWS WAF rate-based rule to allow matching traffic. Associate the web ACL with the CloudFront distribution.
  4. Deploy an AWS WAF web ACL with a block default action in `us-east-1`. Configure an AWS WAF rate-based rule to allow matching traffic. Associate the web ACL with the S3 bucket.
Correct answer: A
Question 4
A company hosts an online shopping portal in the AWS Cloud. The portal provides HTTPS security by using a TLS certificate on an Elastic Load Balancer (ELB). Recently, the portal suffered an outage because the TLS certificate expired. A SysOps administrator must create a solution to automatically renew certificates to avoid this issue in the future. What is the MOST operationally efficient solution that meets these requirements?
  1. Request a public certificate by using AWS Certificate Manager (ACM). Associate the certificate from ACM with the ELB. Write a scheduled AWS Lambda function to renew the certificate every 18 months.
  2. Request a public certificate by using AWS Certificate Manager (ACM). Associate the certificate from ACM with the ELB. ACM will automatically manage the renewal of the certificate.
  3. Register a certificate with a third-party certificate authority (CA). Import this certificate into AWS Certificate Manager (ACM). Associate the certificate from ACM with the ELB. ACM will automatically manage the renewal of the certificate.
  4. Register a certificate with a third-party certificate authority (CA). Configure the ELB to import the certificate directly from the CA. Set the certificate refresh cycle on the ELB to refresh when the certificate is within 3 months of the expiration date.
Correct answer: B
Question 5
A SysOps administrator receives an alert from Amazon GuardDuty about suspicious network activity on an Amazon FC2 instance. The GuardDuty finding lists a new external IP address as a traffic destination. The SysOps administrator does not recognize the external IP address. The SysOps administrator must block traffic to the external IP address that GuardDuty identified Which solution will meet this requirement?
  1. Create a new security group to block traffic to the external IP address. Assign the new security group to the EC2 instance.
  2. Use VPC flow logs with Amazon Athena to block traffic to the external IP address.
  3. Create a network ACL Add an outbound deny rule tor traffic to the external IP address.
  4. Create a new security group to block traffic to the external IP address Assign the new security group to the entire VPC.
Correct answer: C
Question 6
A web application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an Auto Scaling group across multiple Availability Zones. A SysOps administrator notices that some of these EC2 instances show up as healthy in the Auto Scaling group but show up as unhealthy in the ALB target group. What is a possible reason for this issue?
  1. Security groups are not allowing traffic between the ALB and the failing EC2 instances.
  2. The Auto Scaling group health check is configured for EC2 status checks.
  3. The EC2 instances are failing to launch and failing EC2 status checks.
  4. The target group health check is configured with an incorrect port or path.
Correct answer: D
Question 7
A SysOps administrator has enabled AWS CloudTrail in an AWS account. If CloudTrail is disabled, it must be re-enabled immediately. What should the SysOps administrator do to meet these requirements WITHOUT writing custom code?
  1. Add the AWS account to AWS Organizations. Enable CloudTrail in the management account.
  2. Create an AWS Config rule that is invoked when CloudTrail configuration changes.Apply the `AWS-ConfigureCloudTrailLogging` automatic remediation action.
  3. Create an AWS Config rule that is invoked when CloudTrail configuration changes.Configure the rule to invoke an AWS Lambda function to enable CloudTrail.
  4. Create an Amazon EventBridge (Amazon CloudWatch Events) hourly rule with a schedule pattern to run an AWS Systems Manager Automation document to enable CloudTrail.
Correct answer: B
Question 8
A company uses an Amazon Elastic File System (Amazon EFS) file system to share files across many Linux Amazon EC2 instances. A SysOps administrator notices that the file system's `PercentIOLimit` metric is consistently at `100%` for 15 minutes or longer. The SysOps administrator also notices that the application that reads and writes to that file system is performing poorly. They application requires high throughput and IOPS while accessing the file system. What should the SysOps administrator do to remediate the consistently high `PercentIOLimit` metric?
  1. Create a new EFS file system that uses Max I/O performance mode. Use AWS DataSync to migrate data to the new EFS file system.
  2. Create an EFS lifecycle policy to transition future files to the Infrequent Access (IA) storage class to improve performance. Use AWS DataSync to migrate existing data to IA storage.
  3. Modify the existing EFS file system and activate Max I/O performance mode.
  4. Modify the existing EFS file system and activate Provisioned Throughput mode.
Correct answer: D
Question 9
A company needs to restrict access to an Amazon S3 bucket to Amazon EC2 instances in a VPC only. All traffic must be over the AWS private network. What actions should the SysOps administrator take to meet these requirements?
  1. Create a VPC endpoint for the S3 bucket, and create an IAM policy that conditionally limits all S3 actions on the bucket to the VPC endpoint as the source.
  2. Create a VPC endpoint for the S3 bucket, and create an S3 bucket policy that conditionally limits all S3 actions on the bucket to the VPC endpoint as the source.
  3. Create a service-linked role for Amazon EC2 that allows the EC2 instances to interact directly with Amazon S3, and attach an IAM policy to the role that allows the EC2 instances full access to the S3 bucket.
  4. Create a NAT gateway in the VPC, and modify the VPC route table to route all traffic destined for Amazon S3 through the NAT gateway.
Correct answer: B
Question 10
A company migrated an I/O intensive application to an Amazon EC2 general purpose instance. The EC2 instance has a single General Purpose SSD Amazon Elastic Block Store (Amazon EBS) volume attached. Application users report that certain actions that require intensive reading and writing to the disk are taking much longer than normal or are failing completely. After reviewing the performance metrics of the EBS volume, a SysOps administrator notices that the VolumeQueueLength metric is consistently high during the same times in which the users are reporting issues. The SysOps administrator needs to resolve this problem to restore full performance to the application. Which action will meet these requirements?
  1. Modify the instance type to be storage optimized.
  2. Modify the volume properties by deselecting Auto-Enable Volume 10.
  3. Modify the volume properties to increase the IOPS.
  4. Modify the instance to enable enhanced networking.
