Middleware often acts as a bridge between:
- Clients and databases
- Databases and files
- Hardware and software
- Users and servers
Middleware often acts as a bridge between hardware and software, ensuring seamless communication and interaction between these two components.
Using multi-factor authentication can greatly reduce the risk of ________ in cloud environments.
- Account Hijacking
- Data Loss
- Network Intrusion
- Unauthorized Access
Using multi-factor authentication can greatly reduce the risk of "Account Hijacking" in cloud environments by requiring multiple verification methods, making it more challenging for attackers to gain access.
For Azure Functions, what is the primary purpose of Durable Functions?
- Auto-scaling and Load Balancing
- Containerization and Deployment
- Managing HTTP Requests
- Simplifying Asynchronous Workflows
Durable Functions in Azure primarily aim to simplify asynchronous workflows. They enable easy management of stateful, long-running, and parallelizable tasks within serverless functions.
A startup wants to launch a mobile app and expects a variable number of users. They don't want to invest in infrastructure but want to pay based on usage. Which cloud model should they consider?
- IaaS (Infrastructure as a Service)
- On-Premises
- PaaS (Platform as a Service)
- Serverless Computing
IaaS allows the startup to avoid upfront investments, provides scalable infrastructure, and enables them to pay as they go, making it ideal for variable user loads.
In which programming languages can you write Cloud Functions for Google Cloud Platform?
- HTML, CSS
- Java, C++, Ruby
- JavaScript, Python
- Swift, PHP
You can write Google Cloud Functions in languages like JavaScript and Python. These languages are supported for serverless event-driven functions.
What distinguishes SaaS from traditional software deployment?
- Subscription-based pricing
- Local installation
- Customization options
- High initial cost
SaaS (Software as a Service) is characterized by subscription-based pricing, allowing users to pay on a periodic basis. Unlike traditional software, it doesn't require a high upfront cost. It also offers customization options and eliminates the need for local installation.
A large enterprise is planning to move several of its applications to the cloud. They want to ensure that they optimize costs from day one. Which approach should they prioritize?
- Cloud Cost Optimization
- Data Encryption
- Network Bandwidth Expansion
- Software License Agreements Optimization
Prioritizing Cloud Cost Optimization involves carefully planning and managing cloud resources to minimize expenses. It includes right-sizing instances, leveraging reserved instances, and monitoring usage to ensure that costs are optimized from the start of their cloud journey.
When an organization decides to modify or completely change the application's architecture during its migration to the cloud, which strategy is it employing?
- Refactoring (Re-architect)
- Rehosting (Lift and Shift)
- Reimagining (Full Rebuild)
- Replatforming (Lift, Tinker, and Shift)
Refactoring, or Re-architecting, involves modifying or completely redesigning the application's architecture to better leverage the cloud's advantages. It's a strategy for optimizing and improving the application during migration.
A company is looking to deploy a high-performance virtualized environment directly on server hardware without any underlying operating system. Which type of hypervisor would be most suitable?
- Container-based Hypervisor
- Paravirtualization Hypervisor
- Type 1 Hypervisor
- Type 2 Hypervisor
In this scenario, a Type 1 Hypervisor, also known as a bare-metal hypervisor, is most suitable. It runs directly on the server hardware without an underlying OS, offering high performance and minimal overhead.
The integration of IoT and cloud computing enables what kind of analysis on a vast scale?
- Descriptive analysis
- Diagnostic analysis
- Predictive analysis
- Real-time analysis
The integration of IoT and cloud computing enables predictive analysis on a vast scale. IoT devices generate large amounts of data that can be analyzed for future trends and insights.
