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
V! r6 w* T: K3 f& DQUESTION 48
% U+ x5 R- Q5 p6 w1 E6 K1 R/ vWhich two statements about using leased lines for your WAN infrastructure are true? (Choose two.)) V& q9 x) { e4 {, f2 ]# r3 D1 l6 J9 E
A. Leased lines provide inexpensive WAN access.- z& Y) u1 S3 |% r O% C% d
B. Leased lines with sufficient bandwidth can avoid latency between endpoints.
1 c- v" H& l2 z- c1 sC. Leased lines require little installation and maintenance expertise.* L; s* v9 ?/ p, K. o; p) W, t
D. Leased lines provide highly flexible bandwidth scaling.
/ L- V4 @7 m# A+ [) e: ME. Multiple leased lines can share a router interface.
$ k/ N" \% b5 g) Z; ]; {6 J2 D5 gF. Leased lines support up to T1 link speeds.
' L% i X2 |0 x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。
; n7 w/ [! Y% _3 z$ t0 ~: c* Z! i J8 R6 J6 m* Y
还有
4 R* ? ^& S7 H h& @QUESTION 589 E; s8 j* W2 a- X/ l) b) g& G# J
What is the status of port-channel if LACP is misconfigured? r5 `' n% m4 X3 q* s, e$ z
A. Forwarding
3 Q/ a( Z: |% O4 P: f6 GB. Enabled
( h2 C1 W$ ~; `+ g2 LC. Disabled
) m$ k0 I" [; ^3 I! GD. errdisabled
6 y( p3 {; V q. J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。. q: Q9 W4 c1 T/ t9 O
因为看到比较慢,目前发现这些答案跟之前不一致。
. H3 ^$ S! a& c" @不知道有没有大佬能不能出来给个正确答案 |
