Scenario: A company wants to store monthly backups of its data for long-term retention. Which storage class in Google Cloud Platform would be the most cost-effective option for this requirement?
- Nearline
- Coldline
- Archive
- Standard
Understanding the access patterns and requirements of the data helps in selecting the most cost-effective storage class in Google Cloud Platform. For monthly backups that are accessed infrequently but still require quick access when needed, Nearline storage offers a balance between cost and accessibility.
When setting up autoscaling, users need to define _______ to ensure smooth scaling operations.
- Thresholds
- Scripts
- Templates
- Schedules
Defining thresholds is crucial in autoscaling as they determine when scaling actions are initiated, ensuring the system scales up or down in response to actual usage patterns.
What is the main purpose of VPC Service Controls in Google Cloud?
- Enforcing security perimeters for API-based services and data within Google Cloud
- Managing virtual private clouds (VPCs) within Google Cloud
- Optimizing network traffic between different VPCs
- Monitoring resource usage and performance within VPCs
Understanding the main purpose of VPC Service Controls is crucial for ensuring the security of sensitive data and resources within Google Cloud environments. These controls help organizations enforce security policies and prevent unauthorized access to data and services.
Scenario: A company wants to grant access to a group of developers to manage Google Cloud resources. Which IAM feature should they use to accomplish this securely?
- IAM Custom Roles
- IAM Service Accounts
- IAM Policies
- IAM Groups
Utilizing IAM groups allows organizations to efficiently manage access for groups of users, such as developers, by granting them the necessary roles and permissions while maintaining security and compliance.
With Cloud Identity, organizations can enforce _______ policies for user authentication.
- Security
- Billing
- Compliance
- Networking
Enforcing authentication policies with Cloud Identity helps organizations strengthen their security posture and ensure compliance with internal policies and regulatory requirements. By defining and enforcing authentication policies, organizations can mitigate the risk of unauthorized access and data breaches.
Peering allows companies to exchange _______ directly with Google's network at exchange points.
- Traffic
- Data
- Resources
- Permissions
Understanding the purpose of peering helps companies optimize network connectivity for accessing Google Cloud services efficiently and cost-effectively.
_______ is a Google Cloud service that allows users to create custom virtual machine types.
- Google Compute Engine
- Google Cloud Storage
- Google Kubernetes Engine
- Google Cloud Functions
Understanding the capabilities of Google Compute Engine, including its support for creating custom VM types, is crucial for experienced users looking to optimize resource utilization and performance in their cloud environments.
In the context of Google Cloud, what does "infrastructure as code" mean?
- Managing infrastructure using code
- Building physical servers
- Drawing infrastructure diagrams
- Sending emails
Infrastructure as code enables the automated provisioning and management of infrastructure resources through code-based configuration files, promoting consistency, scalability, and efficiency in cloud environments.
How does Google Compute Engine know when to trigger autoscaling?
- By monitoring predefined metrics such as CPU utilization or network traffic and comparing them against configured thresholds.
- By manually specifying the desired scaling behavior through the Google Cloud Console.
- By periodically checking the system load and scaling up or down based on a fixed schedule.
- By sending notifications to administrators who can then manually initiate the scaling process.
Understanding how autoscaling is triggered is essential for efficiently managing resources in Google Compute Engine. By automatically adjusting capacity in response to changing demand, autoscaling helps maintain optimal performance and cost-effectiveness.
What is the primary advantage of using Cloud SQL over managing your own database servers?
- Managed maintenance and automated backups
- Complete control over hardware configuration
- Lower cost
- Limited scalability
Understanding the advantages of using Cloud SQL can help beginners make informed decisions about database management on Google Cloud Platform and leverage managed services effectively for their projects.
VPC Service Controls provide _______ control over data access within a virtual private cloud.
- granular
- centralized
- basic
- automated
Understanding how VPC Service Controls offer granular control over data access within a virtual private cloud is essential for implementing effective security policies and minimizing the risk of unauthorized access to sensitive information.
