Show answer & explanation
Correct answer: D
Concept
A networking acronym has a fixed expansion defined by the relevant standard or layer terminology. At the data-link layer, the MAC sublayer governs access to a shared transmission medium and identifies network interfaces through MAC addresses.
Application
In the phrase ‘MAC address,’ the letters M-A-C expand to ‘Media Access Control.’ Therefore, the required expansion is Media Access Control.
Contrast
Medium Access Card changes the final word to Card and is not the standard networking expansion.
Media Address Command changes both Access and Control and is not the standard networking expansion.
Modem Addressing Card describes neither the data-link sublayer nor the standard acronym.
Cross-check
Networking references commonly expand MAC address as ‘Media Access Control,’ while IEEE 802 formally names the sublayer ‘medium access control.’ The wording distinction does not change the intended MAC acronym in this option set.
Result: Media Access Control.
