Which two switches should you recommend as leaf nodes for a small data center where cost is a factor? (Choose two.)

Question

Options

• AEX4300
• BQFX5700
• CEX4400
• DQFX5130

• A
  76% (25)
• B
  6% (2)
• D
  18% (6)

Explanation

EX4300 and EX4400 are the correct choices because Juniper's EX series switches are designed as cost-effective access and leaf-layer switches suited for small to mid-size deployments, making them the practical fit when budget is a constraint in a small data center.

Why the distractors are wrong:

• QFX5700 (B) is a high-capacity spine/core switch with 400G support targeting large, hyperscale data centers - it is significantly more expensive and over-specced for a small deployment.
• QFX5130 (D) is a high-performance 400G/800G data center switch built for large-scale, high-density spine roles, again carrying a premium price far beyond what a small data center requires.

Memory tip: Think of it this way - EX = Economical/Enterprise access, QFX5700/5130 = eXpensive, eXtra-large. When the question says "small" and "cost is a factor," steer toward the EX series; when it says large-scale or high-density spine, think QFX5700/5130.
