350-801 Question #481: Real Exam Question with Answer & Explanation

Question

Which two describe the main components of the methodology for system sizing adopted by Cisco? (Choose two.)

Options

• APerformance testing measures resource usage (CPU, memory) accurately for each function.
• BCisco TelePresence conductor capacity and sizing can be considered on a region-by-region
• CSystem Busy Hour Call Attempts is calculated by multiplying the number of users by the
• DBusy hour call attempts, where the busy hour call attempts system is the user busy hour call
• EInteraction between individual products may require the addition of Cisco UCM server nodes.

Explanation

Cisco's system sizing methodology involves performance testing to measure resource usage for individual functions and accounting for product interaction, which may necessitate additional server nodes. These two aspects ensure that the system can handle the required workload and inter-product dependencies.

Common mistakes.

• B. While capacity planning can consider regions, "Cisco TelePresence conductor capacity and sizing can be considered on a region-by-region" is too specific and not a general "main component" of the methodology for system sizing.
• C. This statement is an incomplete sentence and does not describe a main component of system sizing methodology, but rather a calculation aspect that is not fully detailed.
• D. This statement is also incomplete and unclear, and does not articulate a core component of the methodology; Busy Hour Call Attempts (BHCA) is a metric, but how it is used as a "main component" of the methodology is not clearly described.
