________ is a strategy where applications are moved to the cloud in their existing form, with the intention of making modifications at a later stage.
- Re-architecting
- Re-factoring
- Re-hosting
- Re-platforming
In the "re-hosting" strategy, applications are migrated as-is to the cloud, with modifications planned for a later phase.
Which cloud service model is best suited for developers who want to focus on code without worrying about the underlying infrastructure?
- Function as a Service (FaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Platform as a Service (PaaS) is the best fit for developers who want to concentrate on coding without managing the infrastructure. PaaS provides the development environment, runtime, and other tools needed for application development, abstracting away the underlying servers and infrastructure concerns.
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.
Which of the following is NOT a major cloud service provider (CSP)?
- Azure
- IBM Cloud
- Open Source Cloud
- Oracle Cloud
IBM, Azure, and Oracle Cloud are major cloud service providers, but "Open Source Cloud" is not a CSP.
Docker is primarily used for:
- Containerization
- Hypervisor
- Orchestration
- Virtualization
Docker is primarily used for containerization, which is the process of packaging and running applications and their dependencies in isolated containers.
An organization is considering using a managed data warehouse solution in the cloud. They are evaluating AWS and Google Cloud. Which respective services from these providers should they compare?
- Amazon Web Services (AWS) - Redshift
- Google Cloud Platform (GCP) - BigQuery
- IBM Cloud - Db2 Warehouse on Cloud
- Microsoft Azure - Azure Synapse Analytics
They should compare AWS Redshift and Google BigQuery. AWS Redshift is a managed data warehousing service by AWS, while Google BigQuery is a similar offering by Google Cloud.
