What is a key difference between Cisco IOS XE's Install Mode and Bundle Mode?

Question

Options

• AInstall Mode requires more RAM during boot than Bundle Mode.
• BBundle Mode extracts packages during boot, increasing boot time.
• CInstall Mode does not support software sub-package patching.
• DBundle Mode is the recommended method by Cisco for IOS XE devices.

• A

• B
  77% (23)
• C
  13% (4)
• D
  7% (2)

Explanation

Bundle Mode boots directly from a single consolidated .bin file, but during that boot process the system must extract individual sub-packages into memory - this extraction step is what increases boot time compared to Install Mode, making B correct. Install Mode pre-extracts packages onto the flash file system before boot, so the router loads them directly without that overhead.

A is backwards: Bundle Mode actually demands more RAM during boot (due to in-memory extraction), not Install Mode. C is the opposite of reality: Install Mode does support sub-package patching - it's actually one of its primary advantages, enabling in-service software upgrades (ISSU) and granular package updates. D is also reversed: Cisco recommends Install Mode, not Bundle Mode, precisely because it offers faster boots, ISSU support, and more flexible patching.

Memory tip: Think of Bundle Mode like a ZIP file - you have to unzip it every time you open it (slowing boot), whereas Install Mode is like files already unzipped on your desktop, ready to use instantly.
