Free Google Cloud Certified - Professional Cloud Architect MCQ Questions and Answers

Question 1

You are creating an intricate architecture that links numerous services to a main database. How should the credentials be safely stored?

Accepted Answer

Leverage a secret management system

Answer

Explanation:
If you need to manage and save your secret keys, use a secrets manager. Hackers search GitHub for inexperienced users who don't secure their secrets, and all too frequently, developers take quick cuts and store their secrets in code, forgetting to remove them when they move to production. One of the main assault vectors in the present day is this one!

Question 2

To replatform is to

Accepted Answer

Optimizing and optimizing your applications and workloads while running them on GCP cloud-native platforms without having to completely rewrite them

Answer

Explanation:
Replatforming is the process of moving your programs from one platform to another, then optimizing them without having to completely rewrite them. If you already have a large number of VMware virtual machines on your local network, you may simply run them on GCE to take advantage of the platform's advantages.

Question 3

You have chosen to create a system that catches and saves all raw data because you are unsure of every potential purpose for the data TerramEarth will gather in the future. What is the most economical way to achieve this objective?

Accepted Answer

Allow the field vehicles to continue FTP data dumps, and configure the Linux machines to use gsutil to promptly transfer the data to Cloud Storage.

Answer

Explanation:
To consume 9 TB per day, multiple load-balanced Compute Engine VMs would be sufficient, and Google Cloud Storage is the least expensive per-byte storage option. Depending on the format, the data may be immediately accessible via BigQuery or shortly after completing an ETL procedure. Thus, while maximizing cost, this approach satisfies both business and technological criteria.

Question 4

By connecting their maintenance tablets to the vehicle, TerramEarth maintenance staff members can now view interactive performance graphs for the previous 24 hours (86,400 occurrences). To assist in problem-solving, the support group wants support personnel to remotely see this data. The graph loads' latency should be as low as possible. How should you go about offering this feature?

Accepted Answer

Execute queries against data indexed by vehicle_id.timestamp in Cloud Bigtable.

Answer

Explanation:
Time-series data is best suited for Cloud Bigtable. It is low-latency, highly available, and economical. It is scalable. The fact that it is a managed service that doesn't need a lot of maintenance work is the best part.

Question 5

Fully autonomous cars are being tested by your farm division. You want your architectural design to support robust security while operating a vehicle. Which two aspects of architecture should you take into account?

Accepted Answer

Treat every microservice call between modules on the vehicle as untrusted.

Answer

Explanation:
Making the system less vulnerable to hacking, particularly man-in-the-middle assaults across modules increase system security.
