Question # 9

What does centralized nature of monolithic applications lead to?

able to scale applications independently, independent application development and deployment, can use diverse technologies for application

able to scale out per module or per service

support agile software development, when we deploy new feature to existing monolith app only duration around 5 second for new traffic

In the lack of being able to scale applications independently, inter-application dependencies that hinder independent application development and deployment, reliability issues due to the centralized nature and the constraints on using diverse technologies for application

Question # 20

For worker nodes, which of the following statements are correct? (Number of correct answers: 3)

Score 2

If worker node capacity is more than 1000 cores, consider using EBM (ECS Bare Metal).

You should choose higher instance specifications, because you can run more tasks on a single

worker node this way, improving utilization.

You should choose the lowest possible instance specification for your workers, to reduce costs.

Ensure redundant worker node capacity for each running pod.

Attach data disk to worker nodes, because Docker image, system logs, and temp data will

consume space. Without a data disk, systems can quickly run out of disk space.
