Explanation

Packet Forwarding (D) is a known limitation because cloud platforms abstract the underlying network infrastructure, preventing tenants from performing low-level packet forwarding operations as you would with physical routers or switches. Cloud providers control the hypervisor and network fabric, so arbitrary packet manipulation - routing packets between interfaces at a raw level - is restricted or unavailable without platform-specific workarounds.

Why the distractors are wrong:

• A (NAT): Network Address Translation is a feature cloud platforms actively provide (e.g., AWS NAT Gateway, Azure NAT), not a limitation.
• B (Custom Route Tables): All major cloud providers support custom route tables within virtual networks (VPCs/VNets), making this a capability, not a constraint.
• C (IAM): Identity and Access Management is a core, mature offering on every major cloud platform - the opposite of a limitation.

Memory tip: Think "what can't you touch?" - cloud platforms hand you the controls (routing tables, NAT, IAM) but keep the engine (raw packet forwarding) locked away behind their abstraction layer. If it sounds like a tool you'd use, it's probably supported; if it sounds like something that happens deep in the hardware, it's likely restricted.
