The concept of accessing computing resources over the internet is closely related to:
- Social networking sites
- Internet of Things (IoT)
- E-commerce
- Cloud Services
Accessing computing resources over the internet is the foundation of cloud services. While the other options do use the internet, they don't represent the idea of harnessing computing power and resources directly over the internet in the same way cloud services do.
If you want to execute a piece of code in response to changes in Google Cloud Storage, you'd typically use ________.
- Google Cloud Dataflow
- Google Cloud Functions
- Google Cloud Pub/Sub
- Google Cloud Tasks
Google Cloud Pub/Sub is often used to trigger code execution in response to changes in Google Cloud Storage, making it a suitable choice.
One of the main benefits of using cloud services for AI and ML is the availability of large-scale ________ for training complex models.
- Data storage and processing
- E-commerce websites
- IoT devices
- Social media platforms
Cloud providers offer extensive data storage and processing capabilities, enabling users to access large datasets for training complex AI and ML models. This resource scalability is a significant benefit.
A tech company has a monolithic application that suffers from long deployment times and scalability issues. They want to transition to a more modular and scalable architecture. What architectural style would you recommend?
- Event-Driven
- Microservices
- Monolithic
- Service-Oriented
The recommendation is to transition to Microservices, which breaks down the monolith into smaller, more manageable, and scalable components.
An organization is concerned about the performance overhead introduced by virtualization layers. They are considering a method where the guest OS is aware of the virtualization and can make direct calls to the physical hardware. Which virtualization technique addresses this?
- Emulation
- Full Virtualization
- Hardware-assisted Virtualization
- Paravirtualization
Paravirtualization is the technique where the guest OS is aware of virtualization and can make direct calls to the physical hardware. This minimizes the performance overhead introduced by virtualization layers.
What is the most common cause of data breaches in organizations?
- Hardware Failure
- Human Error
- Natural Disasters
- Software Bugs
'Human Error' is the most common cause of data breaches, such as accidentally sharing sensitive information or falling for phishing attacks.
A cloud infrastructure that serves a specific community with common concerns (e.g., mission, security requirements, and compliance considerations) is known as:
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
A Community Cloud is designed to serve a specific community with shared concerns like mission, security, and compliance requirements.
Which characteristic of cloud computing allows resources to be provisioned without human interaction?
- High Availability
- Redundancy
- Self-Service Provisioning
- Virtualization
Self-service provisioning enables users to allocate cloud resources independently, reducing the need for manual intervention in resource allocation.
When an organization wants to optimize its application to be more scalable and resilient by redesigning it for the cloud, they are likely using the ________ strategy.
- Re-architecting
- Re-factoring
- Re-hosting
- Re-platforming
The "re-architecting" strategy involves redesigning applications to leverage cloud-native features, enhancing scalability and resilience.
To protect against account hijacking, organizations should enforce a strong ________ policy for cloud services.
- Authentication
- Authorization
- Encryption
- Password
To protect against account hijacking, organizations should enforce a strong "Password" policy for cloud services. This includes requiring strong, unique passwords and periodic password changes.
If a company is interested in using a managed NoSQL database service, which AWS service would be the best fit?
- Amazon DynamoDB
- Amazon RDS
- Amazon Redshift
- Amazon S3
Amazon DynamoDB is a managed NoSQL database service that is designed for scalability and high availability, making it a suitable choice for NoSQL data storage.
