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9 _% n s1 l* r# }! T0 B6 D
QUESTION 489 g. P9 ?& a+ O- ?. c
Which two statements about using leased lines for your WAN infrastructure are true? (Choose two.)
5 z, ?. t; x6 `: B7 JA. Leased lines provide inexpensive WAN access.
5 E6 L D3 r7 @! I+ J, WB. Leased lines with sufficient bandwidth can avoid latency between endpoints.! V! g* A! e9 m& h9 S
C. Leased lines require little installation and maintenance expertise.
5 x2 g6 L/ B$ X) A4 ~: I7 ^D. Leased lines provide highly flexible bandwidth scaling.
& b- q5 {% Q, RE. Multiple leased lines can share a router interface.8 {2 o0 Y: J: R5 ~$ u8 E
F. Leased lines support up to T1 link speeds.
& I" D/ e; J& s6 o8 d0 S" d8 h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。
4 C- ~3 o# k$ a" r4 [) \

QUESTION 58

B. Enabled9 E" H& ]+ z" ]
C. Disabled% ]2 S( q9 a* d- \
D. errdisabled
: ^7 S* O2 c* O* Y; O: ?$ _3 d2 F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 V- S8 }0 N# [& T+ j# j' X
因为看到比较慢,目前发现这些答案跟之前不一致。2 N6 a: B2 R! N2 h7 N$ X$ }
不知道有没有大佬能不能出来给个正确答案 |
