Which metric is commonly used to determine when to scale up or down in autoscaling?
- CPU Utilization
- Disk Space Usage
- Memory Usage
- Network Latency
Understanding which metrics are commonly used for autoscaling helps administrators configure effective scaling policies that respond appropriately to changes in workload demand, ensuring optimal performance and resource utilization.
Scenario: A healthcare organization needs to ensure continuous availability of its patient portal application. How can Cloud Load Balancing be configured to meet this requirement?
- Setting up health checks for backend instances
- Using a single backend instance
- Enabling SSL termination at the load balancer
- Implementing session stickiness
To ensure continuous availability, Cloud Load Balancing should be configured with health checks to monitor the health of backend instances and remove unhealthy ones from the pool, thus maintaining reliable and uninterrupted access to the application.
Cloud CDN reduces _______ by caching content closer to users.
- Latency
- Costs
- Complexity
- Storage
Cloud CDN, or Content Delivery Network, is designed to reduce latency by storing copies of content closer to the end users. This geographical proximity decreases the time it takes for data to travel, leading to faster content delivery.
What is TensorFlow in the context of Google Cloud Platform (GCP)?
- A machine learning framework
- A cloud storage service
- A database management system
- An email service provider
Understanding what TensorFlow is and its role in the Google Cloud Platform ecosystem is crucial for beginners interested in leveraging machine learning capabilities in their projects.
What is the difference between IAM policies and IAM roles?
- IAM policies define the permissions that apply to specific resources or actions, while IAM roles are collections of permissions that can be assigned to users or service accounts.
- IAM policies determine which users have access to GCP resources, while IAM roles define the permissions granted to each user.
- IAM policies and IAM roles serve distinct purposes within GCP's access control model. Policies define permissions, while roles bundle those permissions for assignment to users or service accounts.
- IAM roles determine which resources users can access, while IAM policies specify what actions they can perform.
Understanding the distinction between IAM policies and IAM roles is crucial for designing effective access control strategies in GCP. Policies specify permissions, while roles bundle those permissions for easier assignment, enabling administrators to manage access at scale.
Scenario: An organization wants to automate the deployment and management of Dataproc clusters using Infrastructure as Code principles. Which tool should they use?
- Deployment Manager
- Terraform
- CloudFormation
- Cloud Build
Infrastructure as Code (IaC) principles emphasize automating the provisioning and management of infrastructure using code-based definitions. Google Cloud Deployment Manager is a suitable tool for automating the deployment and management of Dataproc clusters in this scenario.
Google Compute Engine's autoscaler can be configured to use custom _______ for scaling decisions.
- Metrics
- Templates
- Policies
- Algorithms
Using custom metrics in autoscaling provides more precise control over scaling actions, ensuring that the infrastructure scales appropriately based on relevant performance indicators.
Scenario: A project requires complex queries and strong consistency guarantees for transactional data. Which Google Cloud database service is the most suitable choice for this scenario, considering performance and data model requirements?
- Cloud Spanner
- BigQuery
- Cloud SQL
- Firestore
Cloud Spanner's combination of horizontal scalability, strong consistency, and SQL support makes it the most suitable choice for projects requiring complex queries and strong consistency guarantees for transactional data.
What storage class in Google Cloud Storage is suitable for data that is accessed frequently and requires low latency?
- Standard
- Nearline
- Coldline
- Archive
Understanding the different storage classes in Google Cloud Storage and their characteristics is crucial for optimizing storage costs and performance based on the specific needs of the data being stored.
Stackdriver Monitoring allows users to create _______ for monitoring specific conditions and triggering alerts.
- Metrics
- Dashboards
- Instances
- Reports
Metrics are fundamental to Stackdriver Monitoring, allowing users to define the parameters they want to monitor and set up alerts accordingly.
