我之前用的20181204的题库,这次看这个,发现一些题目答案跟以前不一样了。如' E. I6 R2 ~3 n1 q$ Y% g9 C. s
QUESTION 48
; F; _; c. _: k! @) v* cWhich two statements about using leased lines for your WAN infrastructure are true? (Choose two.)
( m2 O d1 b, N: B; wA. Leased lines provide inexpensive WAN access., S( X" Y b y: ~
B. Leased lines with sufficient bandwidth can avoid latency between endpoints.( R% Q4 b% M6 r. }
C. Leased lines require little installation and maintenance expertise.7 i, @- A- ]" C& h; i* Z3 z' |
D. Leased lines provide highly flexible bandwidth scaling.
( e# A7 K- D/ U: s- L0 ZE. Multiple leased lines can share a router interface.
$ m% k+ G- _; O. m& Q9 J1 h9 z, ]% t& SF. Leased lines support up to T1 link speeds.
* i7 w* }6 a p+ u8 ~, m之前是答案是CD,现在BC。觉得答案B,充足的带宽可以消除终端之间的延迟,这个应该是错误的。

还有
2 X: J: ]8 ~ e) D% ^. w4 ]: SQUESTION 58* n; c% ?5 S6 x6 W5 v# T1 A
What is the status of port-channel if LACP is misconfigured?/ f7 q" }& K9 s {/ A! P+ ~
A. Forwarding
- _6 Y. L9 c% y0 T$ nB. Enabled" O1 f9 u% {- w( b4 C8 C3 ~. N
C. Disabled# L9 Q6 J1 t8 z( T4 v
D. errdisabled- T7 f/ d' V" m: |+ H. n% L3 c7 w
之前答案是D,现在答案是C。记得看闫辉老师的题目讲解,这个如果LACP参数不匹配,将进入errdisable状态,应该答案是D。
1 {; V2 T6 q. w/ N) Q因为看到比较慢,目前发现这些答案跟之前不一致。
7 U! j8 B' }* y8 v& k, w) e3 y F不知道有没有大佬能不能出来给个正确答案 |
