Listening Port: The Docker container will be configured to listen on port 5000 using EXPOSE 5000. References: Dockerfile Reference: Dockerfile EXPOSE

  D. DNAC
  C. RESTCONF/YANG

• Question 435:

  A developer writes an application that refines data in temporary secure file storage hosted on the public cloud. Data will be deleted after processing and does not contain any private information. What is the advantage that a public cloud deployment provides to the developer?

  A. high security with encryption
  B. ease in infrastructure management
  C. flexible development
  D. bespoke services
  B. ease in infrastructure management

  ---

  Deploying applications in a public cloud provides several advantages, especially for developers dealing with temporary data processing and secure storage: Ease in Infrastructure Management: Public cloud services offer managed infrastructure, which significantly reduces the operational burden on developers. They do not need to worry about hardware maintenance, scaling, or other infrastructure-related tasks. Scalability: Public clouds provide scalable resources, allowing developers to adjust their infrastructure needs dynamically as per the workload requirements. Cost-Effectiveness: Public clouds often operate on a pay-as-you-go model, which can be more cost-effective for temporary or variable workloads.
