In a blue-green deployment scenario for Tableau Server, what is the primary purpose of maintaining two identical environments?
Correct Answer:C
To provide seamless user experience during upgrades or maintenance The primary purpose of maintaining two identical environments in a blue-green deployment is to ensure a seamless user experience during upgrades or maintenance. This approach allows for one environment (blue) to be active while the other (green) is updated or maintained. Users are then switched over to the updated environment with minimal disruption. Option A is incorrect because using one environment for development and the other for production is not the primary goal of blue-green deployment, which focuses on seamless transitions during updates. Option B is incorrect as A/B testing is not the main objective of blue-green deployment, which is more about minimizing downtime and ensuring service continuity. Option D is incorrect because dividing the workload between servers is not the fundamental purpose of this strategy; rather, it’s about having a ready-to-go, updated environment.
When implementing database encryption for Tableau Server, which step is essential to protect sensitive data at rest?
Correct Answer:B
Configuring Transparent Data Encryption (TDE) on the database used by Tableau Server Configuring Transparent Data Encryption (TDE) on the database used by Tableau Server is essential for encrypting data at rest. TDE ensures that the data stored in the database is encrypted, which protects it from unauthorized access or breaches, especially if the physical storage media is compromised. Option A is incorrect as SSL encryption protects data in transit and does not encrypt data at rest in the database. Option C is incorrect because while a firewall is crucial for net-work security, it does not encrypt data stored in the database. Option D is incorrect as regularly changing passwords, while a good security practice, does not directly relate to the encryption of da-ta at rest in the database.
