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.
________ is a popular tool used for managing and orchestrating containerized applications, making it essential in CI/CD pipelines that utilize containers.
- Docker Compose
- Jenkins
- Kubernetes
- Terraform
Kubernetes is a widely used container orchestration tool. It's crucial in CI/CD pipelines to deploy, manage, and scale containerized applications efficiently.
Which of the following benefits can be attributed to the microservices architecture?
- Decreased development speed, high coupling between services, and centralized control
- Enhanced monolithic architecture, simplified deployment, and limited fault tolerance
- Improved scalability, fault isolation, and easier maintenance
- Reduced code reusability, lack of service independence, and slower time-to-market
Microservices offer various benefits, including improved scalability, fault isolation, and easier maintenance. This architecture allows for independent service scaling, enhancing the application's overall performance and reliability.
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 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.
