________ is a cloud computing service where the cloud vendor provides the hardware and software tools needed for application development to users over the internet.
- Database as a Service (DBaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Platform as a Service (PaaS) offers users the hardware, software, and tools needed for application development. It simplifies the development process by providing a platform for building, testing, and deploying applications without the complexity of managing infrastructure.
A company is looking to securely store sensitive data in the cloud. They want to ensure that even if someone gains access to the data, it would be unreadable. Which technology would you recommend they implement?
- Access Control Lists (ACL)
- Digital Signatures
- Encryption
- Intrusion Detection System (IDS)
Encryption is the best technology to ensure data security in the cloud. It renders data unreadable to unauthorized users even if they gain access to it.
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.
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.
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 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.
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.
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.
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.
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.
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.
Which migration strategy is often the quickest and least expensive initially but might not fully leverage the benefits of the cloud?
- Refactoring (Re-architect)
- Rehosting (Lift and Shift)
- Reimagining (Full Rebuild)
- Replatforming (Lift, Tinker, and Shift)
Rehosting (Lift and Shift) is typically the quickest and least expensive migration strategy initially, but it may not fully exploit the cloud's potential because it doesn't make significant changes to the application's architecture.
