VCP-CMA 2024 Question 33
Select 3You are tasked with preparing the environment for a vRealize Automation (vRA) deployment. During the pre-installation phase, which of the following configurations must be validated to ensure a successful installation?
- A
Ensure that the DNS forward and reverse lookup zones are properly configured and resolvable for all vRA components.
- B
Verify that the NTP servers are reachable and synchronized across all nodes in the environment.
- C
Create a domain user account with administrative privileges on all vRA components to install the software.
- D
Ensure that ports required by vRA components (e.g., 443, 5480) are open between nodes and accessible.
- E
Disable all firewall rules to avoid network connectivity issues during installation.
Show answer and explanation
Correct answers: A, B, D
Explanation
A successful vRealize Automation installation depends on pre-requisites such as DNS resolution, NTP synchronization, and network connectivity. These ensure that components can properly communicate and operate. Properly configured DNS ensures name resolution, while NTP synchronization guarantees time consistency. Additionally, opening required ports allows the components to communicate without compromising security. However, creating overly privileged accounts or disabling firewalls entirely is not best practice and can lead to security vulnerabilities.
- A. Correct.
Correct: Proper DNS configuration, including forward and reverse lookups, is critical for vRA components to communicate effectively.
- B. Correct.
Correct: Time synchronization through NTP is essential to ensure consistent communication and avoid issues with certificates or logs.
- C. Incorrect.
Incorrect: While vRA requires service accounts, they should follow the principle of least privilege and not have administrative privileges across all components.
- D. Correct.
Correct: Ensuring that required ports are open is necessary for communication between vRA components and dependent services.
- E. Incorrect.
Incorrect: Disabling all firewall rules is not recommended as it introduces security risks. Instead, ensure specific required ports are open.
