A Media Company Is Using Amazon RDS for PostgreSQL to Store

question 46

Multiple Choice

A media company is using Amazon RDS for PostgreSQL to store user data. The RDS DB instance currently has a publicly accessible setting enabled and is hosted in a public subnet. Following a recent AWS Well-Architected Framework review, a Database Specialist was given new security requirements. Only certain on-premises corporate network IPs should connect to the DB instance. Connectivity is allowed from the corporate network only. Which combination of steps does the Database Specialist need to take to meet these new requirements? (Choose three.)

• A) Modify the pg_hba.conf file. Add the required corporate network IPs and remove the unwanted IPs.
• B) Modify the associated security group. Add the required corporate network IPs and remove the unwanted IPs.
• C) Move the DB instance to a private subnet using AWS DMS.
• D) Enable VPC peering between the application host running on the corporate network and the VPC associated with the DB instance.
• E) Disable the publicly accessible setting.
• F) Connect to the DB instance using private IPs and a VPN.

Recognize the molecular mechanisms by which various stimuli (e.g., chemical, mechanical) activate specific sensory receptors, leading to the opening or closing of ion channels.

Grasp the principle of sensory adaptation and its behavioral implications, such as the ability to ignore constant stimuli while remaining sensitive to new information.

Explain the distinction between different types of sensory receptors (e.g., chemoreceptors, mechanoreceptors, thermoreceptors, photoreceptors) based on the type of stimulus they detect.

Identify how sensory intensity and sensation type are encoded within the nervous system through the frequency of action potentials and the specificity of receptor cell types.
