Week 08: Assignment 08
1) A lot of platform’s basic building blocks is/are (choose the correct option(s)):
Answer: Containers
Reason: Containers are fundamental building blocks for platform services in cloud and distributed systems. They provide a standardized environment for software to run consistently across various environments.
2) ________ is used to delete a local image.
Answer: Docker rmi
Reason: In Docker, the
docker rmicommand is used to remove one or more images from the local Docker environment. It is specifically designed for deleting images to free up space.
3) Docker Hub is a registry used to host various docker images.
Answer: True
Reason: Docker Hub is a central registry for hosting and sharing container images. Developers use it to store images and make them available for use by others.
4) _______ enables different networks, spreads in a huge geographical area to connect together and be employed simultaneously by multiple users on demand.
Answer: Sensor Cloud
Reason: Sensor Cloud is a cloud computing service where sensor networks are connected over large geographical areas, allowing users to access and use sensor data on-demand from multiple sources.
5) Virtual machines get virtual access to host resources through a _______
Answer: Both a and b (Containers and Hypervisor)
Reason: Virtual machines can access host resources either through hypervisors (which manage VMs on physical hardware) or containers (which run on a host OS without needing a separate hypervisor layer).
6) Vehicles providing their networking and data processing capabilities to other vehicles through the cloud comes under which service of IoT-based Vehicular Data Clouds.
Answer: IaaS
Reason: Infrastructure as a Service (IaaS) in Vehicular Data Clouds provides computing resources, networking, and data processing for connected vehicles to share data with other vehicles.
7) Sensor data can be easily shared by different groups of users without any extra effort or measure.
Answer: False
Reason: Sharing sensor data among different user groups often requires additional efforts such as data access control, privacy policies, and specific data-sharing frameworks.
8) Container is a complete time instance of an image.
Answer: True
Reason: A container is an instance of a Docker image running in an isolated environment. Once a container is launched, it operates as an instance of its base image.
9) In the context of Green Cloud Computing, the Power Usage Effectiveness is defined as
Answer: Overall Power / Power Delivered
Reason: Power Usage Effectiveness (PUE) is a metric used to determine the energy efficiency of a data center. It is calculated as the ratio of total facility energy consumption to the energy used for computing (power delivered).
10) Statement 1: Sensor-Cloud proxy exposes sensor resources as cloud services.
Statement 2: Sensor network is still managed from the Sensor-Cloud Interface via Sensor Network Proxy.
Answer: Both statements are True
Reason: In Sensor-Cloud systems, sensor resources are managed and exposed through cloud services using proxies, which allow seamless access to sensor data while ensuring management through the sensor network interface.
