Quiz - Introducing Google Cloud
Graded Assignment
1. What is the primary benefit to a Google Cloud customer of using resources in several zones within a region?
- For improved fault tolerance
- For better performance
- For expanding services to customers in new areas
- For getting discounts on other zones
Explanation:
Google Cloud divides regions into multiple zones to improve fault tolerance and ensure high availability. If one zone experiences an outage, workloads can continue running in another zone within the same region. This minimizes downtime and enhances reliability.
2. What type of cloud computing service lets you bind your application code to libraries that give access to the infrastructure your application needs?
- Platform as a service
- Infrastructure as a service
- Software as a service
- Hybrid cloud
- Virtualized data centers
Explanation:
PaaS (Platform as a Service) provides a managed environment where developers can run their code without worrying about infrastructure. It includes runtime environments, databases, and development tools. Google App Engine is an example of a PaaS offering in Google Cloud.
- IaaS (Infrastructure as a Service) provides raw computing resources (e.g., virtual machines).
- SaaS (Software as a Service) delivers fully built applications (e.g., Gmail, Google Docs).
- Hybrid cloud & Virtualized data centers are broader concepts related to cloud architecture.
3. Why might a Google Cloud customer use resources in several regions around the world?
- To improve security
- To earn discounts
- To offer localized application versions in different regions.
- To bring their applications closer to users around the world, and for improved fault tolerance
Explanation:
Using multiple regions allows applications to serve users with low latency by hosting services closer to them. It also enhances fault tolerance—if one region fails, another can handle traffic, ensuring high availability and disaster recovery.
