Azure's managed Kubernetes service is abbreviated as ________.
- A-Kube-Service
- AKS
- Azure Kube-Manager
- K8S
Azure's managed Kubernetes service is abbreviated as AKS, which stands for Azure Kubernetes Service. It simplifies deploying, managing, and scaling containerized applications using Kubernetes.
One of the primary benefits of using cloud-based analytics tools like AWS Redshift or Google BigQuery is the ability to scale ________.
- Elastically
- Horizontally
- Statically
- Vertically
Cloud-based analytics tools provide the ability to scale "elastically" by dynamically adjusting resources to meet demand, a key feature for handling varying workloads.
Docker ________ allows users to define and manage multi-container Docker applications.
- Compose
- Engine
- Hub
- Swarm
Docker Compose is the tool that allows users to define and manage multi-container Docker applications. It uses a YAML file to configure the services.
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 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.
One of the primary techniques used by attackers to perform account hijacking is ________.
- Data Backups
- Data Encryption
- Denial of Service Attack
- Phishing
One of the primary techniques used by attackers to perform account hijacking is "Phishing," where they trick users into revealing their credentials. Phishing is a common method of social engineering attacks.
A smart city initiative wants to deploy thousands of sensors across the city to gather data on traffic, pollution, and energy consumption. They want real-time analysis and response. How can they leverage both IoT and cloud computing effectively?
- Deploy the sensors in a mesh network
- Store all data locally on the sensors
- Use edge computing with IoT devices
- Use only IoT devices
In this scenario, leveraging edge computing with IoT devices is essential for real-time analysis. Edge computing processes data locally, reducing latency, and then sends the necessary insights to the cloud. This allows for quick responses in a smart city context.
For persistent storage in Kubernetes, you would typically use a ________.
- ConfigMap
- Persistent Volume (PV)
- Pod
- Secret
Persistent Volumes (PV) are used for persistent storage in Kubernetes. They abstract the underlying storage and provide a way to manage storage resources.
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.
AWS Lambda is an example of ________ computing.
- Edge
- Grid
- Quantum
- Serverless
AWS Lambda is a prominent serverless computing service that allows running code without provisioning or managing servers, making it serverless.
