B) importing data from your file to a table
C) exporting data from a table to your file
D) the set of attributes that is copied from a table into a secondary index

A projection in DynamoDB refers to the set of attributes that are copied from a table into a secondary index, allowing for efficient querying.

Question 11

A user has created a VPC with two subnets: one public and one private. The user is planning to run the patch update for the instances in the private subnet. How can the instances in the private subnet connect to the internet?
A) The private subnet can never connect to the internet
B) Use NAT with an elastic IP
C) Use the internet gateway with a private IP
D) Allow outbound traffic in the security group for port 80 to allow internet updates

Accepted Answer

Instances in a private subnet can connect to the internet using a NAT (Network Address Translation) gateway or instance, which allows them to initiate outbound traffic to the internet while preventing inbound traffic from the internet. The NAT gateway or instance must have an elastic IP address to facilitate this connection.

Question 12

In DynamoDB, to get a detailed listing of secondary indexes on a table, you can use the ______ action.
A) BatchGetItem
B) TableName
C) DescribeTable
D) GetItem

Accepted Answer

The DescribeTable action in DynamoDB provides detailed information about a table, including its secondary indexes.

Question 13

A user has created a VPC with a public subnet. The user has terminated all the instances which are part of the subnet. Which of the below mentioned statements is true with respect to this scenario?
A) The subnet to which the instances were launched with will be deleted
B) When the user launches a new instance it cannot use the same subnet
C) The user cannot delete the VPC since the subnet is not deleted
D) Secondary network interfaces attached to the terminated instances may persist.

Accepted Answer

Secondary network interfaces attached to the terminated instances may persist even after the instances are terminated, as they are separate resources that need to be explicitly deleted.

Question 14

DynamoDB usesonly as a transport protocol, not as a storage format.
A) WDDX
B) XML
C) SGML
D) JSON

Accepted Answer

DynamoDB uses JSON as a transport protocol for data exchange, but it does not use JSON as a storage format.

B) The user would need to create a default route to IGW in subnet's route table and then attach an elastic IP to the instance to connect from the internet
C) The user can directly attach an elastic IP to the instance
D) The instance will never launch if the public IP is not assigned

Accepted Answer

The user needs to create a route to the Internet Gateway (IGW) in the subnet's route table and attach an Elastic IP to the instance to enable internet connectivity.
