H12-811_V1.0 · Question #904
As shown in the figure, if host A has the ARP cache of host B, host A can ping host B.
The correct answer is A. TRUE. If host A already has host B's MAC address in its ARP cache, it can send packets directly to host B without needing to perform an ARP request. This cached information allows immediate packet delivery, assuming no network changes have occurred that would invalidate the ARP entry.
