    Which of the following is a key characteristic of cloud

    computing? 
    A High latency in data access Correct Answer Incorrect Answer
    B Resource pooling Correct Answer Incorrect Answer
    C Manual software updates Correct Answer Incorrect Answer
    D Fixed resource allocation Correct Answer Incorrect Answer
    E Lack of scalability Correct Answer Incorrect Answer

    Solution

    Resource pooling is a fundamental characteristic of cloud computing that allows multiple customers (tenants) to share and efficiently utilize the same physical resources. This model leverages a multi-tenant environment where resources like storage, processing power, and memory are dynamically allocated and reassigned according to demand. This not only optimizes resource utilization but also reduces costs, as providers can manage a larger number of clients using the same underlying infrastructure. Resource pooling facilitates elastic scalability, allowing organizations to quickly adjust their resource consumption based on workload requirements, making it easier to handle fluctuations in demand. The shared nature of resources also enhances the flexibility and agility of cloud environments, enabling rapid deployment of applications and services. Option A (High latency in data access) - High latency contradicts the cloud's design principles, as cloud computing aims to minimize latency to provide responsive services. Providers use advanced networking and caching techniques to ensure low latency. Option C (Manual software updates) - One of the advantages of cloud computing is that many cloud service providers manage software updates automatically, reducing administrative overhead for users. This characteristic allows users to focus on their core business activities rather than maintaining software. Option D (Fixed resource allocation) - Fixed resource allocation is contrary to the cloud's dynamic nature. Cloud services are designed to allocate resources flexibly based on current needs, allowing for scalability and efficient resource management. Option E (Lack of scalability) - Scalability is one of the primary benefits of cloud computing. Cloud services allow organizations to scale their resources up or down quickly in response to changing demands, making them more agile.
