請問這幾題有爭議嗎?

which two statements are true regarding EIGRP? (Choose two)

A.Passive routes are in the process of being calculated by DUAL
B.EIGRP supports VLSM,route summarization,and routing update authentication.
E. Aquery process is used to discover a replacement for a failed route if a feasible successor
is not identified from the current routing information.

題目給的答案是BE，但是我覺得A也可以....請問這題有爭議嗎?

E的答案好像怪怪的..feasible successor 不是存在 拓撲表的嗎?

4.OSPF routing use the concept of areas.what are the characteristics of OSPF
areas ?(choose three)

A.Each OSPF area requires a loopback interface to be configuarded.
B.Areas may be assigned any number from 0 to 65535.
C.Araas 0 is called the backbone area
D.Hierarchical OSPF network do not require multiple areas.
E.Multiple OSPF areas must connect to area 0.

題目給的答案是:BCE
可是B的答案..AREAS number應該是 0-42億多吧...

我是覺得A..也可以選.. 雖然說 loopback是沒有強制說一定要用。

A.Each OSPF area requires a loopback interface to be configuarded
-------

因為這句是說每條OSPF的area都要設定一個loopback

實際上這樣做是多餘的，所以不對


A.Passive routes are in the process of being calculated by DUAL
------------------

Passive route是被動路由，原本用來設定讓FastEthernet不接收更新

所以不會被計算在EIGRP的路徑成本

基本上八竿子打不著
