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8 c: Z! L& [- o( F8 [
QUESTION 486 X/ ^' k' r# p9 o1 r* b# G
Which two statements about using leased lines for your WAN infrastructure are true? (Choose two.)9 b: h* R" a" }9 |& C* Q, [$ b- b
A. Leased lines provide inexpensive WAN access.
% X( R* {$ i) w# P, zB. Leased lines with sufficient bandwidth can avoid latency between endpoints.
% H" ]& j2 x- _! O( i1 T: W0 }C. Leased lines require little installation and maintenance expertise.) |2 h: p# A+ g7 p
D. Leased lines provide highly flexible bandwidth scaling./ X& U6 v! Q/ c8 o6 k o, {! R/ M
E. Multiple leased lines can share a router interface.
% r5 @6 ]6 g" S- y4 D- A0 sF. Leased lines support up to T1 link speeds.2 }/ S V7 f& g
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。
5 j% o: Y0 X9 O2 b2 T6 \8 P! A& o$ M8 G3 ]; Q
还有
& z, S$ f2 S% w8 MQUESTION 586 {+ G, Q% T4 G' ~/ t
What is the status of port-channel if LACP is misconfigured?
! X6 T2 p- D. ^5 X, W/ T+ v9 P6 jA. Forwarding5 S/ \. o1 I9 P, k$ n
B. Enabled! I! e& W& t' g
C. Disabled
) ^& x5 ~* U p: P4 }D. errdisabled5 ]7 r, C, b/ c' A
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。2 q6 i* _* b& P, u p$ z- H
因为看到比较慢,目前发现这些答案跟之前不一致。
