A solutions architect is tasked with transferring 750 TB of data from a network-attached file system located at a branch office Amazon S3 Glacier.
The solution must avoid saturating the branch office’s low-bandwidth internet connection.
What is the MOST cost-effective solution?
A.
Create a site-to-site VPN tunnel to an Amazon S3 bucket and transfer the files directly. Create a bucket policy to enforce a VPC endpoint.
B.
Order 10 AWS Snowball appliances and select an S3 Glacier vault as the destination. Create a bucket policy to enforce a VPC endpoint.
C.
Mount the network-attached file system to Amazon S3 and copy the files directly. Create a lifecycle policy to transition the S3 objects to
Amazon S3 Glacier.
D.
Order 10 AWS Snowball appliances and select an Amazon S3 bucket as the destination. Create a lifecycle policy to transition the S3 objects
to Amazon S3 Glacier.
A company has a two-tier application architecture that runs in public and private subnets. Amazon EC2 instances running the web application are
in the public subnet and a database runs on the private subnet. The web application instances and the database are running in a single Availability
Zone (AZ).
Which combination of steps should a solutions architect take to provide high availability for this architecture? (Choose two.)
A.
Create new public and private subnets in the same AZ for high availability.
B.
Create an Amazon EC2 Auto Scaling group and Application Load Balancer spanning multiple AZs.
C.
Add the existing web application instances to an Auto Scaling group behind an Application Load Balancer.
D.
Create new public and private subnets in a new AZ. Create a database using Amazon EC2 in one AZ.
E.
Create new public and private subnets in the same VPC, each in a new AZ. Migrate the database to an Amazon RDS multi-AZ deployment.
A company has deployed an API in a VPC behind an internet-facing Application Load Balancer (ALB). An application that consumes the API as a
client is deployed in a second account in private subnets behind a NAT gateway. When requests to the client application incre ase, the NAT
gateway costs are higher than expected. A solutions architect has configured the ALB to be internal.
Which combination of architectural changes will reduce the NAT gateway costs? (Choose two.)
A.
Configure a VPC peering connection between the two VPCs. Access the API using the private address.
B.
Configure an AWS Direct Connect connection between the two VPCs. Access the API using the private address.
C.
Configure a ClassicLink connection for the API into the client VPC. Access the API using the ClassicLink address.
D.
Configure a PrivateLink connection for the API into the client VPC. Access the API using the PrivateLink address.
E.
Configure an AWS Resource Access Manager connection between the two accounts. Access the API using the private address.
PrivateLink, expose one VPC to another VPC
ClassicLink usually is not an answer rather a distracter
Resource Access Manager is to allow multiple accounts share one VPC
So AD
Lifecycle management: create in S3 standard then move to Glacier
after a while. Glacier is an alternative to on premise tape storage.
So D
HA, must be multi AZ
ASG, ALB, and DB must span multi AZ, so B and E, done
