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.
Google Cloud Functions can be triggered by events from which of the following Google Cloud services?
- Google Cloud Bigtable
- Google Cloud Compute Engine
- Google Cloud Pub/Sub
- Google Cloud Storage
Google Cloud Functions can be triggered by events from Google Cloud Pub/Sub, making it easy to build event-driven applications.
In terms of data analytics, what advantage does AWS Redshift provide over traditional databases?
- ACID Compliance and High Throughput
- Columnar Storage and Parallel Processing
- Document Store and Strong Consistency
- Graph Database and Horizontal Scaling
AWS Redshift is designed for data warehousing and analytics, offering columnar storage and parallel processing for improved performance.
In which migration strategy might an organization choose to break a monolithic application into microservices?
- Lift and Shift
- Rearchitect/Rebuild
- Refactor/Re-architect
- Rehost/Replatform
The "Refactor/Re-architect" strategy involves restructuring the existing application to make it more suitable for the cloud. Breaking a monolithic app into microservices falls under this category.
The principle that suggests that any code commit that passes all stages of the CI/CD process is ready for deployment to production is known as ________.
- Continuous Approval (CA)
- Continuous Deployment (CD)
- Continuous Integration (CI)
- Continuous Verification (CV)
Continuous Deployment (CD) is the principle where any code that passes all stages in the CI/CD pipeline is automatically deployed to production, promoting a fast and reliable release process.
Phishing attacks primarily target which aspect of cloud accounts for hijacking?
- Application Code
- Cloud Configuration
- Server Hardware
- User Credentials
Phishing attacks primarily target user credentials. Attackers use deceptive tactics to trick users into revealing their login information, which can then be used for unauthorized access.
A primary distinction between Type-1 and Type-2 hypervisors is:
- The ability to run multiple virtual machines
- The need for virtualization support in hardware
- The presence of a host OS
- The use of hardware
Type-1 hypervisors run directly on the hardware without the need for a host OS, while Type-2 hypervisors run on top of an existing OS. This is a fundamental difference in their architecture.
An e-commerce company during the holiday season wants to temporarily augment its existing private cloud capacity with additional resources from an external cloud provider. Which combined cloud model are they considering?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
A hybrid cloud combines private and public cloud resources. It allows the e-commerce company to extend its private cloud with public cloud resources temporarily, meeting increased demand during the holiday season.
