Amazon EC2 instances for the application tier running in private subnets need to download software patches from the internet. However, the EC2 instances cannot be directly accessible from the internet.  \nWhich actions should be taken to allow the EC2 instances to download the needed patches? (Select  \nTWO.)  \nA) Configure a NAT gateway in a public subnet.  \nB) Define a custom route table with a route to the NAT gateway for internet traffic and associate it with the private subnets for the application tier.  \nC) Assign Elastic IP addresses to the EC2 instances.  \nD) Define a custom route table with a route to the internet gateway for internet traffic and associate it with the private subnets for the application tier.  \nE) Configure a NAT instance in a private subnet.  \n2) A solutions architect wants to design a solution to save costs for Amazon EC2 instances that do not need to run during a 2-week company shutdown. The applications running on the EC2 instances store data in instance memory that must be present when the instances resume operation.  \nWhich approach should the solutions architect recommend to shut down and resume the EC2 instances?  \nA) Modify the application to store the data on instance store volumes. Reattach the volumes while restarting them.  \nB) Snapshot the EC2 instances before stopping them. Restore the snapshot after restarting the instances.  \nC) Run the applications on EC2 instances enabled for hibernation. Hibernate the instances before the 2-week company shutdown.  \nD) Note the Availability Zone for each EC2 instance before stopping it. Restart the instances in the same Availability Zones after the 2-week company shutdown.  \n3) A company plans to run a monitoring application on an Amazon EC2 instance in a VPC. Connections are made to the EC2 instance using the instance’s private IPv4 address. A solutions architect needs to design a solution that will allow traffic to be quickly directed to a standby EC2 instance if the application fails and becomes unreachable.  \nWhich approach will meet these requirements?  \nA) Deploy an Application Load Balancer configured with a listener for the private IP address and register the primary EC2 instance with the load balancer. Upon failure, de-register the instance and register the standby EC2 instance.  \nB) Configure a custom DHCP option set. Configure DHCP to assign the same private IP address to the standby EC2 instance when the primary EC2 instance fails.  \nC) Attach a secondary elastic network interface to the EC2 instance configured with the private IP address. Move the network interface to the standby EC2 instance if the primary EC2 instance becomes unreachable.  \nD) Associate an Elastic IP address with the network interface of the primary EC2 instance. Disassociate the Elastic IP from the primary instance upon failure and associate it with a standby EC2 instance.  \n4) An analytics company is planning to offer a web analytics service to its users. The service will require that the users’ webpages include a JavaScript script that makes authenticated GET requests to the company’s Amazon S3 bucket.  \nWhat must a solutions architect do to ensure that the script will successfully execute?  \nA) Enable cross-origin resource sharing (CORS) on the S3 bucket.  \nB) Enable S3 Versioning on the S3 bucket.  \nC) Provide the users with a signed URL for the script.  \nD) Configure an S3 bucket policy to allow public execute privileges.  \n5) A company’s security team requires that all data stored in the cloud be encrypted at rest at all times using encryption keys stored on premises.  \nWhich encryption options meet these requirements? (Select TWO.)  \nA) Use server-side encryption with Amazon S3 managed encryption keys (SSE-S3) .  \nB) Use server-side encryption with AWS KMS managed encryption keys (SSE-KMS) .  \nC) Use server-side encryption with customer-provided encryption k","cbCaip5eJxm6KrLt","https://ap.wps.com/l/cbCaip5eJxm6KrLt","pdf",188881,"English","# Network and EC2 connectivity\n## Private subnets patch access using NAT\n## Route tables vs gateways\n## DHCP and failover IP assignment\n\n# EC2 lifecycle and availability\n## Cost optimization during shutdown\n## Hibernation vs snapshot\n## Regional/AZ restart considerations\n\n# Web access and security\n## Authenticated JavaScript requests to S3\n## CORS and signed URLs\n## Encryption at rest with customer-controlled keys\n\n# Capacity and workload scaling\n## Reserved instances during demand spikes\n## Spot/on-demand vs resizing reservations\n## Vote processing without downtime","[{\"question\":\"What changes ensure traffic can be quickly redirected to a standby EC2 instance if the primary becomes unreachable?\",\"answer\":\"Use an Application Load Balancer configured to register the primary instance, then deregister it and register the standby instance upon failure.\"}]","AWS Certified Solutions Architect Associate - Sample Questions | PDF",1789932677,13]
