Chapter 8

1. 2 and 4

The Neptune VPC endpoint won't be used to import from S3.

You do need an S3 endpoint, so this is correct.

The EC2 does need to access S3, so this isn't correct.

Neptune will need an IAM role to access S3, so this is correct.

S3 will not be reading from Neptune so it does not need an IAM role.

2. 3

You cannot delete from Timestream, so that is the only correct answer.

3. 4

QLDB only supports 20 tables, so you have hit the maximum allowed.

4. 1 and 5

Gremlin and SPARQL are the only languages supported by Neptune.

5. 1

The _ql_committed tables show all the history for any modifications, and this is the correct answer.
