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.

Which of the following is NOT typically a function of middleware?

  • Data Storage and Retrieval
  • Message Routing
  • Security
  • User Interface
Middleware primarily handles tasks like data storage and retrieval, security, and message routing. User interface management is typically outside the scope of middleware.

Which of the following scenarios is best suited for a hybrid cloud model?

  • A company with a strict data residency requirement
  • A research institution with high computing demands
  • A small business with minimal data
  • A startup looking for low costs
A hybrid cloud model is ideal for organizations with varying data residency needs, allowing them to use both public and private clouds, maintaining control over data in the private portion.

Account hijacking can lead to unauthorized data access, making it crucial to monitor and log all ________ in cloud environments.

  • Activities
  • Logins
  • Requests
  • Resources
Account hijacking can lead to unauthorized data access, making it crucial to monitor and log all "Logins" in cloud environments. Monitoring and logging login activities can help detect and respond to unauthorized access.

Which practice can potentially lead to account hijacking if not managed properly?

  • Regular system backups
  • Regular system updates
  • Strong encryption practices
  • Weak or reused passwords
Weak or reused passwords can potentially lead to account hijacking when not managed properly, as attackers can easily guess or obtain such passwords. Proper management is crucial for security.

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.
