Which autoscaling method requires the VM to temporarily shut down while it processes system modification?

Question

Options

• ABoth Vertical and Horizontal Scaling
• BVertical Scaling
• CHorizontal Scaling
• DNeither autoscaling method requires the VM to shutdown

• A
  2% (1)
• B
  88% (46)
• C
  6% (3)
• D
  4% (2)

Explanation

Vertical Scaling (scaling up) requires resizing a VM's CPU, RAM, or storage - a process that typically demands a reboot to apply the hardware-level changes, causing temporary downtime. Horizontal Scaling (scaling out) avoids downtime entirely by adding or removing additional VM instances without touching existing ones, so option C is wrong. Option A is wrong because horizontal scaling does not require shutdown, and option D is wrong because vertical scaling clearly does. Option B alone correctly identifies the one method that forces a temporary shutdown.

Memory tip: Think of "Vertical = Vulnerable" - you must take the machine down to build it up, while horizontal scaling just spins up neighbors without disturbing anyone.
