Which of the following models provides tools to support application development, such as development frameworks, databases, and caching systems?
- 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) provides a comprehensive environment for application development. It includes development frameworks, databases, and caching systems, allowing developers to build and deploy applications without worrying about managing the infrastructure or the underlying services.
Reserved instances in cloud services primarily help in:
- Enhancing network speed and reliability
- Ensuring data confidentiality
- Reducing infrastructure costs
- Streamlining code deployment
Reserved instances in cloud services help reduce infrastructure costs by allowing users to commit to long-term usage of specific cloud resources, typically at a lower hourly rate compared to on-demand instances. This commitment ensures cost savings.
An e-commerce company is expecting a huge surge in traffic during a sale event. They want to ensure that they have the flexibility to quickly scale up or down their infrastructure resources. Which cloud service model would best fit their needs?
- Function as a Service (FaaS)
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
The e-commerce company should opt for Infrastructure as a Service (IaaS). IaaS allows them to scale resources as needed, making it suitable for handling traffic spikes. It provides control over infrastructure.
Account hijacking can lead to which of the following unauthorized actions?
- Enhanced User Experience
- Improved Application Performance
- Increased Cloud Storage
- Unauthorized Data Access
Account hijacking can lead to unauthorized access to data, which can result in data breaches and loss of sensitive information.
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 global manufacturing company wants to standardize its operations across all its units. They need a system to integrate various functions like HR, finance, and production. Which software solution would you recommend?
- Customer Relationship Management (CRM)
- Enterprise Resource Planning (ERP)
- Human Resource Management (HRM)
- Supply Chain Management (SCM)
Enterprise Resource Planning (ERP) integrates various functions across an organization, making it the ideal choice for standardization across units.
Edge computing in the context of IoT refers to processing data at the ________ rather than in a centralized cloud server.
- Cloud
- Edge
- Network
- Periphery
Edge computing means processing data closer to the data source (IoT devices) rather than in a distant centralized cloud server. This reduces latency and bandwidth usage.
Companies that are concerned about the security of their data in a SaaS model might explore ________ options to ensure data encryption.
- Backup
- Encryption
- Networking
- Virtualization
Data encryption is a common security measure in SaaS. Encrypting data ensures that even if unauthorized access occurs, the data remains protected.
A software development company is in need of a cloud service where they can develop, run, and manage applications without the complexity of building and maintaining the infrastructure. Which essential characteristic of cloud computing would address their requirement?
- Elasticity
- Redundancy
- Scalability
- Self-Service On-Demand
Self-Service On-Demand is a fundamental cloud characteristic that allows developers to provision resources as needed, removing the need for infrastructure management.
An organization is looking to consolidate their server infrastructure to optimize resource usage and reduce costs. By implementing which type of virtualization can they achieve this?
- Application Virtualization
- Network Virtualization
- Server Virtualization
- Storage Virtualization
Server virtualization is the ideal choice for consolidating server resources, enabling multiple VMs on a single physical server, optimizing resource usage, and reducing costs.
