Question

Which of the following resource has following graph structure for web servers?

(a) Network I/O

(b) RAM

(c) Disk

(d) None of the mentioned

I have been asked this question during an internship interview.

I'd like to ask this question from Resource Ceilings in portion Abstraction and Virtualization Layer and Capacity Planning of Cloud Computing

Answer 1

The question seems to be asking about a resource related to web servers that operates with a graph structure. Let's break down the options:

• Network I/O: This is often associated with data transmission over a network and can be represented in various ways, including as graphs, especially when tracking connections or data flow between nodes. It can have a graph structure in some contexts, such as visualizing network paths or connections between different network nodes.

• RAM: RAM is typically handled in terms of memory allocation and usage, not usually represented in a graph structure. It’s more about chunks of memory being used or allocated to processes.

• Disk: Disk usage is also typically tracked in terms of blocks, sectors, or filesystem structures, not necessarily as a graph. However, in some advanced monitoring tools, graphs can represent disk usage patterns over time.

• None of the mentioned: This would imply that none of the options above have a graph structure, which doesn't seem likely for Network I/O in specific contexts.

Given this, the most plausible answer, based on your question about web servers and graph structures, is (a) Network I/O. The graph structure might refer to visualizing or analyzing network connections, throughput, or paths between servers, which is common in web server management and monitoring.
