Question 1 of 30

In a Cisco ACI environment, you are tasked with configuring Endpoint Groups (EPGs) for a multi-tier application that consists of a web tier, an application tier, and a database tier. Each tier has specific requirements for communication and security policies. The web tier needs to communicate with the application tier using HTTP and HTTPS, while the application tier must access the database tier using SQL queries. Given that the application tier also needs to communicate with external services, which of the following configurations would best ensure that the EPGs are set up correctly to meet these requirements while adhering to best practices for security and traffic management?

Create three separate EPGs for the web, application, and database tiers, and configure contracts that allow HTTP/HTTPS traffic between the web and application EPGs, and SQL traffic between the application and database EPGs. Additionally, implement a contract for external communication from the application EPG to the outside world, ensuring that all traffic is monitored and controlled.

Combine the web and application tiers into a single EPG and create a separate EPG for the database tier, allowing all traffic between the combined EPG and the database EPG without any restrictions.

Create a single EPG for the entire application stack, allowing unrestricted communication between all components, including external services, to simplify management.

Establish separate EPGs for each tier but allow all types of traffic between them without implementing any contracts, assuming that security policies will be managed at the external firewall level.
