Access Point:
- Supports both 802.11 and 802.3 standards (how else would an AP be able to traffic data between the wireless and wired network?)
- Formats an Ethernet frame and forwards it to a destination (think in terms of encapsulation; the AP receives Layer 1 wireless signals and converts them into Layer 2 frames)
WLC:
- Used on-prem and/or cloud-based (think WLC deployment models; unified being a hardware appliance deployed in a central location of the network, and cloud-based being a VM running in a server, typically in a private cloud in a data center)
- provides centralized management and security
Regarding the misconception of AP's being on-prem and/or cloud-based... although an AP's management can be cloud-based (Cisco Meraki being a cloud-based AP management solution), the AP itself is a physical device.

Access Point (AP)
✔ Formats an Ethernet frame and forwards to a destination
✔ Supports both IEEE 802.11 and Ethernet standards
Wireless LAN Controller (WLC)
✔ Provides centralized management and security
✔ Used on-premise and/or cloud-based
❌
In LWAP mode, the AP does not make forwarding decisions—it relies on the WLC for that.
Little bit tricky, they are using exclusive terms to confuse you. pay attention to my notes
AP -
formats an ethernet frame and forwards to a destination
Supports both IEEE 802.11 and Ethernet standards
WLC -
Provides Centralized MGT and Security (a given)
can be used on prem or cloud based (AP will be cloud managed, the WLC would be cloud based)
Not used-
makes forwarding decisions when in LWAP mode (only the AP can be in LWAP mode, the ##WLC can support an AP in LWAP, but is not in LWAP mode itself, so it cannot be WLC)
##When an AP is in LWAP mode, it is having the WLC make the forwarding decisions, so this cannot apply to the AP either.
given answers are incorrect
Access Point:
used on-premise and/or cloud-based
supports both IEEE 802.11 and Ethernet standards
Wireless LAN Controller:
provides centralized management and security
makes forwarding decisions when in LWAP mode

read bellow
In a cloud-managed WLAN architecture, organizations
don’t have to purchase physical controllers and deploy them on every site. The “cloud” mentioned here works like a virtual controller that actually reside in a
public cloud, and all the distributed wireless access points connect to it via the Internet. The cloud offers remote provisioning, monitoring and troubleshooting to
every access point.
A controlled access point or (LWAP) is not capable of taking any forwarding decision. After receiving a frame from a connected device, the controlled access point forwards it to the WLC instead of the destination device. Next, WLC decides whether the received frame should be delivered or discarded based on the security configuration. If the frame is required to be forwarded, then WLC sends that frame to that (LWAPP) that is connected to the destination device. Subsequently, LWAPP transfers this frame to the destination device.
Wouldn't be the first point be an argument for WLC "used on-premise and/or cloud-based"?
Also: WLC cannot be "in LWAP mode". AP can be in LWAP mode, but does not make "forwarding decisions".
*Access Point*
Used on promise or cloud
Supports both IEEE 802.11 and 802.3
*WLC*
Provides centralized management
Make forwarding decision in LWAP mode
