For applications with global users, which IBM Cloud feature is most critical to reduce latency?

Question

Options

• AGlobal Load Balancer
• BLocal disk storage options
• CDedicated Hosts
• DVirtual Private Network (VPN)

• A
  72% (33)
• B
  17% (8)
• C
  7% (3)
• D
  4% (2)

Explanation

Global Load Balancer (A) reduces latency for worldwide users by intelligently routing traffic to the nearest or best-performing data center, minimizing the physical distance data must travel. This geographic distribution is the defining solution for latency problems at a global scale.

Why the others are wrong:

• B (Local disk storage): Storage type affects I/O speed on a single server, not network latency across regions - it's a local optimization, not a global one.
• C (Dedicated Hosts): These provide physical isolation for compliance or performance consistency, but a dedicated server in one location still serves distant users with high latency.
• D (VPN): A VPN secures network traffic but can actually increase latency due to encryption overhead; it doesn't route users to closer servers.

Memory tip: Think of "Global" in the answer matching "global users" in the question - when the problem is global reach, the solution name literally contains "Global." Load balancers balance traffic across locations, so global users get served locally.
