Referring to the exhibit, Host A on Node device node2 and Host B on Node device node5 are on the same VLAN but Host A cannot ping Host B.
Host A's MAC address is 00:00:02:00:00:01.
Host B's MAC address is 00:00:05:00:00:01.
What is causing this problem?
A. Host B is not connected to Node device node5.
B. The MAC address of Host A is not learned in node2.
C. The MAC address of Host A is not in the RPDf table of Node device node5.
D. The MAC address of Host B is not learned in node5.
Q7. Host A is connected to two Node devices in a redundant server Node group over a LAG link. Host B is connected to a Node device on a server Node group. Traffic is running between Host A and Host B.
Which statement is true?
