One of your fellow developers has come to you for suggestion on provisioning throughput in Dynamo DB . What would you suggest?

if you want to exceed throughput rates of 10,000 write capacity units or 10,000 read capacity units for an individual table, you must first contact Amazon

The smallest provisioned throughput you can request is 1 write capacity unit and 1 read capacity unit

DynamoDB is designed to scale without limits.

All of the above statements are valid

You have created a VPC with CIDR block 10.0.0.0/24, which supports 256 IP addresses. You want to now split this into two subnets, each supporting 128 IP addresses. Can this be done and if so how will the allocation of IP addresses be configured?

One subnet will use CIDR block 10.0.0.0/127 (for addresses 10.0.0.0 - 10.0.0.127) and the other will use CIDR block 10.0.0.128/255 (for addresses 10.0.0.128 - 10.0.0.255).

One subnet will use CIDR block 10.0.0.0/25 (for addresses 10.0.0.0 - 10.0.0.127) and the other will use CIDR block 10.0.0.128/25 (for addresses 10.0.0.128 - 10.0.0.255).

One subnet will use CIDR block 10.0.0.0/25 (for addresses 10.0.0.0 - 10.0.0.127) and the other will use CIDR block 10.0.1.0/25 (for addresses 10.0.1.0 - 10.0.1.127).

No. This can't be done.

A user has created an Amazon Elastic Block Store instance in the US-East-1a Availability Zone. The user has a volume of 40 GB in the US-East-1b zone. How can the user attach the volume to an instance?

Use the volume replicate function to create a new volume in the US-East-1a and attach that to the volume

Since both the volume and the instance are in the same region, the user can attach the volume

Use the volume migrate function to move the volume from one AZ to another and attach to the instance

Take a snapshot of the volume. Create a new volume in the USEast-1a and attach that to the instance
