VCP-CMA 2024 Question 17
Single answerA cloud administrator is tasked with deploying a multi-tier application in a VMware vRealize Automation (vRA) environment. The application requires a database server and a web server to communicate securely. The administrator must configure network isolation between the application and other workloads while allowing communication between the database and web server. Which feature in vRealize Automation should the administrator use to achieve this?
- A
On-demand NAT network
- B
On-demand private network
- C
On-demand routed network
- D
External network
Show answer and explanation
Correct answer: C
Explanation
The correct answer is 'On-demand routed network' because it allows the creation of an isolated network with routing capabilities. This ensures secure communication between the database and web server while maintaining isolation from other workloads in the vRA environment. Other options, such as NAT or private networks, do not meet all the requirements of the scenario.
- A. Incorrect.
An on-demand NAT network is used to create a network with NAT (Network Address Translation) capabilities, which allows workloads to access external resources securely. However, it does not provide the level of isolation and intra-application communication required for this scenario.
- B. Incorrect.
An on-demand private network provides network isolation for workloads but does not allow communication between the database and web server within the application.
- C. Correct.
An on-demand routed network creates isolated networks with routing capabilities, enabling secure communication between workloads (e.g., database and web server) within an application. It also ensures isolation from other workloads.
- D. Incorrect.
An external network connects workloads to an external network infrastructure and does not provide the required level of isolation or secure intra-application communication.
