VCP-VMC 2024 Question 18
Select 3A company is planning to deploy a multi-tier application in a VMware Cloud environment. The application consists of a web front-end, an application server, and a database server. The company wants to ensure secure communication between the tiers and enable scalability. Which cloud network architecture components should be considered for this deployment?
- A
Use a software-defined networking (SDN) solution to segment traffic between tiers using distributed firewalls.
- B
Deploy a single flat network for all tiers to simplify communication and management.
- C
Leverage load balancers to distribute traffic across multiple web front-end instances.
- D
Use NSX-T for micro-segmentation to enforce security policies between application tiers.
- E
Disable network isolation between tiers to maximize performance.
Show answer and explanation
Correct answers: A, C, D
Explanation
A multi-tier application in a cloud environment requires careful consideration of network segmentation, security, and scalability. Using SDN and micro-segmentation (e.g., with NSX-T) ensures secure communication between tiers, while load balancers provide scalability to handle traffic efficiently. Avoiding flat networks and ensuring isolation are critical to maintaining a secure and scalable cloud network architecture.
- A. Correct.
Using an SDN solution, such as VMware NSX, allows for traffic segmentation and security enforcement between application tiers, which is essential for secure communication.
- B. Incorrect.
Deploying a single flat network is not recommended for multi-tier applications because it lacks segmentation and security, thereby increasing the risk of lateral movement in case of a breach.
- C. Correct.
Load balancers are critical for distributing traffic across multiple web front-end instances, which enhances scalability and availability in the cloud network architecture.
- D. Correct.
NSX-T micro-segmentation enables fine-grained security policies between application tiers, ensuring that only necessary traffic is allowed between components.
- E. Incorrect.
Disabling network isolation would compromise the security of the multi-tier application, making it vulnerable to unauthorized access and breaches.
