GCP_PDE_Pub_Sub

A large enterprise using GCP has recently acquired a startup that has an IoT platform. The acquiring company wants to migrate the IoT platform from an on-premises data center to GCP and wants to use Google Cloud managed services whenever possible. What GCP service would you recommend for ingesting IoT data?

• Cloud Storage

• Cloud SQL

• Cloud Pub/Sub

• Cloud Spanner

You are using Cloud Pub/Sub to buffer records from an application that generates a stream

of data based on user interactions with a website. The messages are read by another service

that transforms the data and sends it to a machine learning model that will use it for train-

ing. A developer has just released some new code, and you notice that messages are sent

repeatedly at 10-minute intervals. What might be the cause of this problem?

• The new code release changed the subscription ID.

• The new code release changed the topic ID.

• The new code changed the subscription from pull to push.

• The new code disabled acknowledgments from the consumer.

It is considered a good practice to make your processing logic idempotent when consuming messages from a Cloud Pub/Sub topic. Why is that?

• Messages may be delivered multiple times.

• Messages may be received out of order.

• Messages may be delivered out of order.

• A consumer service may need to wait extended periods of time between the delivery of

  messages.

Your department is migrating some stream processing to GCP and keeping some on premises. You are tasked with designing a way to share data from on-premises pipelines that use Kafka with GPC data pipelines that use Cloud Pub/Sub. How would you do that?

• Stream data to a Cloud Storage bucket and read from there

• Use CloudPubSubConnector and Kafka Connect

• Write a service to read from Kafka and write to Cloud Pub/Sub

• Use Cloud Pub/Sub Import Service

The Inventory team's subscriber only receives messages that are published after the subscription was created.

• True

• False
