• Chose C1

  Immutable infrastructure means that once infrastructure is deployed, you don't modify the existing resource in place. Instead, when you need a change: Create new infrastructure → validate it → switch traffic → remove old infrastructure

• Chose D1

  AI said its D.

• Chose D2

  D. Less complex infrastructure upgrades is the correct advantage of immutable infrastructure. Immutable infrastructure treats servers, VMs, or resources as immutable (unchanging once deployed). To apply updates, fixes, or changes, you create entirely new instances from a known, versioned image or template and then replace (or decommission) the old ones, rather than modifying them in place. This contrasts with mutable infrastructure, where you update existing resources directly (e.g., via patches, config changes, or SSH).
