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
. k. e. M) L" z4 {8 L6 j' HQUESTION 48& E: K8 w* q" W- _" G8 j
Which two statements about using leased lines for your WAN infrastructure are true? (Choose two.): K; D6 {0 c$ ~/ i
A. Leased lines provide inexpensive WAN access.& D. `4 y$ |0 B8 [- k6 `
B. Leased lines with sufficient bandwidth can avoid latency between endpoints., e$ a+ P* w, J: g" a6 @- y( C7 e
C. Leased lines require little installation and maintenance expertise.
" ~' V3 p0 D' W! F5 N" [; i0 a) wD. Leased lines provide highly flexible bandwidth scaling.
4 J( n5 t* D* Y* M2 N bE. Multiple leased lines can share a router interface.4 @" H6 M( z E
F. Leased lines support up to T1 link speeds. y: q E+ b$ P' n8 P1 G0 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。5 [( ^. W9 t h
( G, H5 }" x$ O7 o还有3 `% t( z: m5 j# p, I2 d; }
QUESTION 58" R. Z' W" D" }6 c/ K9 s5 S
What is the status of port-channel if LACP is misconfigured?
& p; y3 E: W* E2 ZA. Forwarding( v1 @: w9 T4 y8 ^1 {
B. Enabled, A2 {4 E4 W1 o# J0 Y
C. Disabled. ? `/ w' o2 d8 r' m1 h2 h" d3 k- L
D. errdisabled, S, e' e, _3 p: e8 T$ 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。
6 Y2 N' j7 y$ n% W2 w因为看到比较慢,目前发现这些答案跟之前不一致。
1 \' R- R; v* y( G5 b( D不知道有没有大佬能不能出来给个正确答案 |
