In the context of AI in the cloud, what does a pre-trained model refer to?
- A model that is trained on new data
- A model that is trained on public data
- A model that requires further training
- A model that was trained by a user
A pre-trained model refers to a machine learning model that has already been trained on a large dataset and is available for use without further training. Typically, these models are trained on publicly available data.
Which type of cloud is made available to the general public by cloud service providers?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
A "Public Cloud" is a cloud infrastructure made available to the general public by service providers. It is shared by multiple organizations and is typically accessed over the internet. Public clouds offer scalability and cost-efficiency.
A media company wants to automate the process of video transcoding whenever a new video file is uploaded to their Amazon S3 bucket. Which AWS service would be most suitable for this scenario?
- AWS Data Pipeline
- AWS Elastic Transcoder
- AWS Glue
- AWS Lambda
AWS Elastic Transcoder is specifically designed for video transcoding tasks. It automatically transcodes videos when new files are uploaded to an S3 bucket, making it a suitable choice for the media company's automation needs.
In a cloud-based CI/CD pipeline, what role does a container registry like Docker Hub or Google Container Registry play?
- Managing Cloud Resources
- Running Tests
- Storing Configuration
- Storing Containers
Container registries like Docker Hub or Google Container Registry store Docker images, which are key for deploying containers in the CI/CD pipeline.
Which type of cloud provides more control over security and compliance for its users?
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
A Private Cloud offers more control over security and compliance because it's dedicated to a single organization, allowing customization and stricter governance.
Unlike traditional databases, data lakes can store structured, semi-structured, and ________ data.
- Encrypted
- Indexed
- Relational
- Unstructured
Data lakes are known for their ability to store a variety of data types, including "unstructured" data, such as text documents, making them versatile for data storage.
What does "Account Hijacking" in cloud computing refer to?
- Excessive use of cloud resources
- Gaining physical access to cloud servers
- Inadequate network security in the cloud
- Unauthorized access to a user's cloud account by an attacker
Account hijacking refers to unauthorized access to a user's cloud account by an attacker who gains access to sensitive information or controls the account.
Which of the following best describes cloud computing?
- A model for accessing computing resources over the internet
- A physical location for data storage
- A service for virtual reality gaming
- A technology for weather forecasting
Cloud computing is a model that enables the on-demand access to computing resources like servers, storage, and databases over the internet. It's not about weather forecasting or VR gaming.
In Kubernetes, which object allows you to maintain a stable IP address for pods as they are rescheduled?
- ConfigMap
- PodDisruptionBudget
- Secret
- Service
A Kubernetes Service is used to maintain a stable IP address for pods. It acts as an abstraction layer over a set of pods, allowing access to them through a consistent DNS name or IP address. This ensures that clients can reach the pods, even if they are rescheduled.
The characteristic of cloud computing that ensures that a user can control and manage the computing resources, even if they don't control the underlying infrastructure, is called:
- Resource Pooling
- Resource Virtualization
- Scalability as a Service
- Virtual Machine Management
The essential characteristic referred to here is "Resource Pooling." It allows users to control and manage computing resources, abstracting the underlying infrastructure. Resources are pooled together for better utilization and management.
