Which statement best describes the principle of least privilege? Adding an IAM user into at least one IAM group Checking a packet's permissions against an access control list Granting only the permissions that are needed to perform specific tasks Performing a denial of service attack that originates from at least one device
Granting only the permissions that are needed to perform specific job tasks. When you grant permissions by following the principle of least privilege, you prevent users or roles from having more permissions than needed to perform specific job tasks. For example, cashiers in the coffee shop should be given access to the cash register system. As a best practice, grant IAM users and roles a minimum set of permissions and then grant additional permissions as needed.
An employee requires temporary access to create several Amazon S3 buckets. Which option would be the best choice for this task? AWS account root user IAM group IAM role Service control policy (SCP)

It is stateless and allows all inbound and outbound traffic. Network access control lists (ACLs) perform stateless packet filtering. They remember nothing and check packets that cross the subnet border each way: inbound and outbound. Each AWS account includes a default network ACL. When configuring your VPC, you can use your account's default network ACL or create custom network ACLs. By default, your account's default network ACL allows all inbound and outbound traffic, but you can modify it by adding your own rules. For custom network ACLs, all inbound and outbound traffic is denied until you add rules to specify which traffic should be allowed. Additionally, all network ACLs have an explicit deny rule. This rule ensures that if a packet doesn't match any of the other rules on the list, the packet is denied.
