What is one reason mat customers struggle to obtain data center network visibility when thoy use legacy approaches?

Question

Options

• ALegacy monitoring toots require IT to manually correlate data to obtain insights, and they offer
• BMost data center switches lack full CLI support, and they fail to provide show commands, which
• CLegacy approaches to network visibility rely on analytics that are built into network infrastructure
• DMost customers are using only one management tool to monitor their complete data center

• A
  76% (16)
• B
  5% (1)
• C
  14% (3)
• D
  5% (1)

Explanation

Option A is correct because legacy monitoring tools - such as SNMP-based platforms and traditional NMS systems - were designed to collect raw data but require IT staff to manually correlate information across multiple sources before any meaningful insight can be derived. This manual correlation is slow, error-prone, and fails to provide the real-time, unified visibility that modern data centers demand.

Why the distractors are wrong:

• B is false because most modern and even legacy data center switches do support CLI and show commands - lack of CLI access is not the core visibility problem.
• C is backwards; legacy approaches typically lack built-in analytics - it's actually modern/next-gen solutions that embed analytics into the infrastructure.
• D is incorrect because the problem is typically the opposite: organizations use too many siloed tools, not just one, which contributes to the correlation challenge described in A.

Memory tip: Think of legacy tools as giving you raw puzzle pieces with no picture on the box - the data exists, but IT must manually assemble the picture themselves. Modern visibility solutions assemble the puzzle automatically. The keyword to watch for in exam questions is "manual correlation" - that phrase almost always points to legacy limitations.
