An organization has setup RDS with VPC. The organization wants RDS to be accessible from the internet. Which of the below mentioned configurations is not required in this scenario?
Correct Answer:
C
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user’s AWS account. It enables the user to launch AWS resources, such as RDS into a virtual network that the user has defined. Subnets are segments of a VPC's IP address range that the user can designate to a group of VPC resources based on security and operational needs. A DB subnet group is a collection of subnets (generally private) that the user can create in a VPC and which the user assigns to the RDS DB instances. A DB subnet group allows the user to specify a particular VPC when creating DB instances. If the RDS instance is required to be accessible from the internet:
The organization must setup that the RDS instance is enabled with the VPC attributes, DNS hostnames and DNS resolution.
The organization must enable the parameter in the console which makes the RDS instance publicly accessible.
The organization must allow access from the internet in the RDS VPC security group. Reference: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_VPC.html

An organization is setting up RDS for their applications. The organization wants to secure RDS access with VPC. Which of the following options is not required while designing the RDS with VPC?
Correct Answer:
A
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user’s AWS account. It enables the user to launch AWS resources, such as RDS into a virtual network that the user has defined. Subnets are segments of a VPC's IP address range that the user can designate to a group of VPC resources based on security and operational needs. A DB subnet group is a collection of subnets (generally private) that the user can create in a VPC and assign to the RDS DB instances. A DB subnet group allows the user to specify a particular VPC when creating the DB instances.
Each DB subnet group should have subnets in at least two Availability Zones in a given region. If the RDS instance is required to be accessible from the internet the organization must enable the VPC attributes, DNS hostnames and DNS resolution. For each RDS DB instance that the user runs in a VPC, he should reserve at least one address in each subnet in the DB subnet group for use by Amazon RDS for recovery actions.
