Which migration strategy might lead to higher costs in the long run if the application isn't optimized post-migration to take advantage of cloud-native features?
- Rearchitect (rebuild)
- Refactor (re-architect)
- Rehost (lift and shift)
- Repurchase (buy a new one)
Rehosting (lift and shift) can lead to higher costs in the long run if the application isn't optimized post-migration. It essentially migrates the application as is without leveraging cloud-native benefits.
Which service model is most appropriate for businesses that have significant existing investments in software licenses and want to maintain a higher degree of control over their application environment?
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
- Function as a Service (FaaS)
In this case, Infrastructure as a Service (IaaS) is the best option, as it allows the business to leverage their existing software investments and maintain control over the underlying infrastructure.
Which of the following is NOT a typical feature of cloud monitoring tools?
- Auto-scaling and Load Balancing
- Billing and Cost Management
- Code Compilation and Execution
- Log Aggregation and Analysis
Cloud monitoring tools are primarily focused on tracking and analyzing system performance, resource utilization, and errors. Code compilation and execution are not typically associated with cloud monitoring but rather belong to the domain of development and build tools.
How are you billed for Google Cloud Functions?
- Flat Monthly Fee
- Free tier available
- Pay-as-you-go
- Pay-per-Request
Google Cloud Functions are billed based on the number of requests and the time your code executes. It's a pay-per-request model, ensuring you only pay for what you use.
Which of the following strategies is often used when an organization wants to migrate quickly to meet a business objective but plans on optimizing later?
- Lift and Shift
- Rearchitect/Rebuild
- Refactor/Re-architect
- Rehost/Replatform
The "Lift and Shift" strategy involves migrating an application to the cloud quickly with minimal changes. Organizations often use this when they need rapid migration with optimization as a later step.
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.
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.
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.
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.
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.
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.
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.
