Why is a service type of network typically isolated on different hardware?
A service type of network is typically isolated on different hardware because it has distinct functions from other networks. By isolating the service network, it ensures that the specific tasks and services it is responsible for can be managed, controlled, and optimized without interference from or causing disruption to other networks. This separation enhances performance, reliability, and management efficiency, ensuring each network operates effectively within its defined scope.
The service type of network is typically isolated on different hardware for the following reason: C. It has distinct functions from other networks. A service type of network often serves a specific purpose or function that is different from other networks within a cloud environment. Isolating it on different hardware allows for better control and management of resources dedicated to that particular network. By separating it from other networks, it becomes easier to allocate resources, optimize performance, and apply specific configurations or settings tailored to the unique requirements of that network. This isolation helps prevent interference or conflicts between different network types, ensuring efficient and reliable operation of each network within the cloud environment.
We most commonly see at least three different networks which are isolated onto dedicated hardware since there is no functional or traffic overlap: - The service network for communications between virtual machines and the Internet. This builds the network resource pool for the cloud consumers. - The storage network to connect virtual storage to virtual machines. A management network for management and API traffic.
correct answer C
C. A service type of network typically supports specific functions such as management, storage, or application, and therefore it is isolated on different hardware to maintain its own infrastructure and prevent it from affecting other networks in case of any failure or compromise.
A service type of network, in the context of cloud computing, is typically isolated on different hardware because it serves distinct functions from other networks. In cloud environments, different types of networks are used to provide various services and functionalities.
See page 78 of Security Guidence. The below mentioned clarifications are correct.
BTW the Answer D is also good if we see this text from chapter 7.2 of Security Guidance: "If you are a cloud provider (including managing a private cloud), physical segregation of networks composing your cloud is important for both operational and security reasons. We most commonly see at least three different networks which are isolated onto dedicated hardware since there is no functional or traffic overlap:"
