The application reliability team at your company this added a debug feature to their backend service to send all server events to Google Cloud Storage for eventual analysis. The event records are at least 50 KB and at most 15 MB and are expected to peak at 3,000 events per second. You want to minimize data loss.
Which process should you implement?

• A.* Append metadata to file body
  * Compress individual files
  * Name files with a random prefix pattern
  * Save files to one bucket
• B.* Append metadata to file body
  * Compress individual files
  * Name files with serverName - Timestamp
  * Create a new bucket if bucket is older than 1 hour and save individual files to the new bucket.
  Otherwise, save files to existing bucket.
• C.* Compress individual files
  * Name files with serverName - EventSequence
  * Save files to one bucket
  * Set custom metadata headers for each object after saving
• D.* Batch every 10,000 events with a single manifest file for metadata
  * Compress event files and manifest file into a single archive file
  * Name files using serverName - EventSequence
  * Create a new bucket if bucket is older than 1 day and save the single archive file to the new bucket.
  Otherwise, save the single archive file to existing bucket.

Your company has successfully migrated to the cloud and wants to analyze their data stream to optimize operations. They do not have any existing code for this analysis, so they are exploring all their options. These options include a mix of batch and stream processing, as they are running some hourly jobs and live-processing some data as it comes in. Which technology should they use for this?

• A.Google Cloud Dataproc
• B.Google Cloud Dataflow
• C.Google Container Engine with Bigtable
• D.Google Compute Engine with Google BigQuery

To speed up data retrieval, more vehicles will be upgraded to cellular connections and be able to transmit
data to the ETL process. The current FTP process is error-prone and restarts the data transfer from the
start of the file when connections fail, which happens often. You want to improve the reliability of the
solution and minimize data transfer time on the cellular connections.
What should you do?

• A.Directly transfer the files to different Google Cloud Multi-Regional Storage bucket locations in US, EU,
  and Asia using Google APIs over HTTP(S). Run the ETL process using the data in the bucket
• B.Directly transfer the files to a different Google Cloud Regional Storage bucket location in US, EU, and
  Asia using Google APIs over HTTP(S). Run the ETL process to retrieve the data from each Regional
  bucket
• C.Use multiple Google Container Engine clusters running FTP servers located in different regions. Save
  the data to Multi-Regional buckets in US, EU, and Asia. Run the ETL process using the data in the
  bucket
• D.Use one Google Container Engine cluster of FTP servers. Save the data to a Multi-Regional bucket.
  Run the ETL process using data in the bucket

The JencoMart security team requires that all Google Cloud Platform infrastructure is deployed using a
least privilege model with separation of duties for administration between production and development
resources.
What Google domain and project structure should you recommend?

• A.Create two G Suite accounts to manage users: one for development/test/staging and one for
  production. Each account should contain one project for every application
• B.Create two G Suite accounts to manage users: one with a single project for all development
  applications and one with a single project for all production applications
• C.Create a single G Suite account to manage users with each stage of each application in its own project
• D.Create a single G Suite account to manage users with one project for the development/test/staging
  environment and one project for the production environment

Correct Answer: D

Explanation/Reference:
Explanation:
Note: The principle of least privilege and separation of duties are concepts that, although semantically
different, are intrinsically related from the standpoint of security. The intent behind both is to prevent people
from having higher privilege levels than they actually need
Principle of Least Privilege: Users should only have the least amount of privileges required to perform

their job and no more. This reduces authorization exploitation by limiting access to resources such as
targets, jobs, or monitoring templates for which they are not authorized.
Separation of Duties: Beyond limiting user privilege level, you also limit user duties, or the specific jobs

they can perform. No user should be given responsibility for more than one related function. This limits
the ability of a user to perform a malicious action and then cover up that action.
