Answer: Increase the node count of the compute cluster where the web service is deployed.
The question requires improving performance with minimal downtime and minimal administrative effort. Option B (Increase the node count of the compute cluster) is optimal because it scales horizontally to handle increased inferencing load without service interruption, as confirmed by community consensus (75% support) and comments highlighting zero downtime and minimal effort. Option C (Increase the minimum node count) is less suitable as it maintains higher costs year-round without necessarily improving peak performance. Option A involves significant administrative overhead (redeployment, DNS updates) and downtime. Option D (Increase VM size) requires cluster reconfiguration and causes downtime, contradicting the minimal downtime requirement.

You need to improve the performance of a multi-class image classification web service that is failing to meet demand despite having a fully utilized compute cluster. The solution must minimize both downtime and administrative effort.
What should you do?
A
Create a new compute cluster by using larger VM sizes for the nodes, redeploy the web service to that cluster, and update the DNS registration for the service endpoint to point to the new cluster.
B
Increase the node count of the compute cluster where the web service is deployed.
C
Increase the minimum node count of the compute cluster where the web service is deployed.
D
Increase the VM size of nodes in the compute cluster where the web service is deployed.
