When considering cold starts in Google Cloud Functions, which runtime generally has the fastest initialization time?
- Go
- Java
- Node.js
- Python
In Google Cloud Functions, Go generally has the fastest cold start initialization time due to its efficient runtime. This is important for minimizing latency.
The ________ is a set of security standards designed to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment.
- FERPA
- HIPAA
- PCI DSS
- SOX
PCI DSS (Payment Card Industry Data Security Standard) is a comprehensive set of security standards designed to protect credit card information and ensure that companies maintain a secure environment when handling such data.
The primary role of the back end in a cloud computing environment is to:
- Handle user authentication
- Host user interfaces
- Manage server hardware
- Manage servers
The back end in cloud computing is responsible for managing servers, handling data, and executing the core functionalities of the application. It's the "invisible" part.
Google Cloud's equivalent to AWS's RDS (Relational Database Service) is ________.
- Bigtable
- CloudSQL
- Datastore
- Firestore
Google Cloud's counterpart to AWS RDS is CloudSQL, which offers managed relational databases like MySQL and PostgreSQL.
Which of the following best describes cloud computing?
- A way to store personal photos and videos
- A method for companies to save on IT operational costs
- A system to play online games
- Delivering computing services over the internet
Cloud computing is about delivering various computing services like storage, databases, servers, networking, software, and more over the internet. While some of the other options may be components or uses of cloud computing, the core idea is the delivery of computing services via the internet.
A company has a legacy application that is tightly coupled with its current database. They want to migrate to the cloud and modernize the application for better scalability and performance. Which migration strategy should they consider?
- Rearchitecting (rebuilding)
- Refactoring (re-architecting)
- Rehosting (lift-and-shift)
- Retiring or Decommissioning
Refactoring, or re-architecting, is the most suitable strategy when migrating to the cloud while modernizing an application. It involves making application changes to optimize for the cloud environment, ensuring scalability and performance.
Which of the following is a primary function of middleware in a cloud computing environment?
- Installing applications
- Load balancing
- Managing user data
- Server hardware maintenance
A primary function of middleware in cloud computing is load balancing, which evenly distributes network traffic to optimize resource utilization.
In a microservices architecture, the pattern that isolates failures and ensures that a failure in one service doesn't impact others is called the ________ pattern.
- Adapter
- Circuit Breaker
- Observer
- Singleton
The Circuit Breaker pattern is used to isolate failures in a microservices architecture. It prevents a single service failure from cascading through the system.
Continuous monitoring in cloud environments is essential for:
- Detecting and mitigating threats
- Ensuring high availability of services
- Monitoring competitors' cloud usage
- Reducing cloud infrastructure costs
Continuous monitoring in the cloud is crucial for detecting and mitigating security threats, ensuring data protection, and maintaining compliance with regulations. It's not primarily about cost reduction or monitoring competitors.
