CLOUD-DIGITAL-LEADER Online Practice Questions and Answers

Correct Answer: C

Preemptible VMs:

Predictable and low cost

Preemptible VMs are up to 80% cheaper than regular instances. Pricing is fixed so you will always get low cost and financial predictability, without worrying about variable market pricing.

Expand your batch processing

Supplement your regular VMs with lower-cost, preemptible instances to finish your compute-intensive work faster, saving you time and money. Throw preemptible VMs at fault-tolerant workloads such as high performance computing, big data

and analytics, continuous integration/continuous delivery (CI/CD), rendering/transcoding, and testing.

Get more from your containers

Containers are naturally stateless and fault tolerant, making them a great fit for preemptible VMs! You save on your containerized workloads today with these affordable compute instances. Take advantage of Google Kubernetes Engine for

your containerized workloads and Managed Instance Groups to painlessly and seamlessly recover from preemptions.

Enable it instantly

Simply add--preemptible to the gcloud command line and you're off to the races. There's no bidding to code for, and with per-second billing, just shut down your VMs as soon as you're done.

Correct Answer: A

Preemptible VMs are cost-effective instances that can be used for short-lived and non-critical workloads. Since the rendering of individual scenes takes less than 12 hours and can be interrupted and restarted, you can leverage preemptible VMs to perform the rendering tasks. Preemptible VMs are available at a significantly lower cost compared to regular instances but can be preempted by GCP with a 30-second notice. By designing your rendering workflow to handle interruptions gracefully, such as checkpointing and resuming, you can take advantage of the cost savings provided by preemptible VMs. https://cloud.google.com/compute/docs/instances/preemptible

Key features:

Fully managed

Cloud SQL automatically ensures your databases are reliable, secure, and scalable so that your business continues to run without disruption. Cloud SQL automates all your backups, replication, encryption patches, and capacity increases-

while ensuring greater than 99.95% availability, anywhere in the world. Integrated Access Cloud SQL instances from just about any application. Easily connect from App Engine, Compute Engine, Google Kubernetes Engine, and your workstation. Open up analytics possibilities by using BigQuery to directly query your Cloud SQL databases. Reliable Easily configure replication and backups to protect your data. Go further by enabling automatic failover to make your database highly available. Your data is automatically encrypted, and Cloud SQL is SSAE 16, ISO 27001, and PCI DSS compliant and supports HIPAA compliance. Easy migrations to Cloud SQL Database Migration Service (DMS) makes it easy to migrate your production databases to Cloud SQL with minimal downtime. This serverless offering eliminates the manual hassle of provisioning, managing, and monitoring migration-specific resources. DMS leverages the native replication capabilities of MySQL and PostgreSQL to maximize the fidelity and reliability of your migration. And it's available at no additional charge for native like-to-like migrations to Cloud SQL.

Correct Answer: D

Cloud Datastore is the best for semi-structured application data that is used in app engines' applications. Bigtable is best for analytical data with heavy read/write events like AdTech, Financial or IoT data. Cloud Storage is best for structured and unstructured, binary or object data like images, large media files and backups. SQL is best for web frameworks and in existing applications like storing user credentials and customer orders. Cloud Spanner is best for large scale database applications that are larger than two terabytes; for example, for financial trading and e-commerce use cases. As I mentioned at the beginning of the module, depending on your application, you might use one or several of these services to get the job done.

Correct Answer: AB

Autoscaling is supported in both Flexible and Standard environments. Flexible Environment does run a Docker container that includes a custom runtime or source code written in other programming languages.
