Practice Test 1 | Google Cloud Certified Professional Data Engineer | Dumps | Mock Test
You have a Dataflow pipeline to run and process a set of data files received from a client, for transformation and loading into a data warehouse. This pipeline should run each morning so that metrics can be ready when stakeholders need the latest stats based on data sent the day before. Which tool should you use?
A. Cloud Functions
B. Compute Engine
C. Kubernetes Engine
D. Cloud Composer
Correct Answer: D
The question is asking to suggest a name of service that can be used to trigger to schedule a dataflow pipeline.
A: Cloud Functions
Cloud Functions can be written in Node.js, Python, Go, Java, .NET, Ruby, and PHP programming languages, and are executed in language-specific runtimes. This can be invoked HTTP functions from standard HTTP requests. These HTTP requests wait for the response and support handling of common HTTP request methods like GET, PUT, POST, DELETE and OPTIONS
Hence this is not a correct solution.
B: Compute Engine
This is a VM and hence not a service to schedule a dataflow pipeline. Hence this is not a correct solution.
C: Kubernetes Engine
This is work on model of Master and node and hence not correct solution.
D: Cloud Composer
Cloud Composer is a fully managed workflow orchestration service, enabling you to create, schedule, monitor, and manage workflows that span across clouds and on-premises data centers.
Hence this is a correct solution
