In the TestKing network shown above, switch TestKing1 has just been restarted and has passed the POST routine. Host TestKingA (the one on the left) sends its initial frame to Host TestKingC. What is the first thing the switch will do as regards to populating the switching table?
A. Switch TestKing1 will add 192.168.23.12 to the switching table
B. Switch TestKing1 will add 192.168.23.4 to the switching table
C. Switch TestKing1 will add 000B.DB95.2EE9 to the switching table
D. Switch TestKing1 will add 000A.8A47.E612 to the switching table
E. None of the above
D吧~~
都說是 Host TestKingA (the one on the left) sends its initial frame to Host TestKingC...
所以封包是從左邊傳來的..SW要先紀錄來源路徑.才發送廣播封包給其他台...
印象中SW是屬於L2的..所以主要是紀錄MAC..........
這題其實是二選一題型...選b或d..很少有人會選到C的...
add 000A.8A47.E612 會先被寫進 mac table
000B.DB95.2EE9 之後會被寫進 mac table
順序是這樣
