D. switch port connected to other switches
E. host-facing links
Which two components?
Agreed the correct answer is A & D and this is the reference you can use
https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/15-0_1_se/configuration/guide/3750xcg/swmacsec.html
Here is the full quetion:
An engineer is configuring MACsec encryption. Which two components does Cisco TrustSec NDAC MACsec support?
In this case the answer is A&D.
If the question were “which two components does MKA MACsec encryption support?” then the answer will be B & C.

Ensure to read the question and understand the requirement.
GOOD!

it depends on the question for this questions is BC
User-facing downlink ports, Switch-to-host, MKA MACsec encryption
An engineer is configuring MACsec encryption. Which two components does Cisco TrustSec NDAC MACsec support? (Choose two.).
A,D
Switchports connected to other switches, Switch-to-switch, Cisco TrustSec NDAC MACsec
According to that link A and D are the correct answer

Switchports connected to other
switches
Switch-to-switch Cisco TrustSec NDAC MACsec

The actual full question is: An engineer is configuring MACsec encryption. Which two components does Cisco TrustSec NDAC MACsec support? (Choose two.).
TrustSec NDAC (Network Device Admission Control) MACsec is used only between switch-to-switch. The only instance MACsec is used with hosts is MACsec MKA. These exact terms and descriptions are on the Cisco website so the answer to the question that mentions NDAC, is definitely switch to switch and switch ports connected to other switches.
