CCNA考試情況及心得體會

試題情況(2015/12/16,南京)

• 選擇題全出自題庫但選項順序有改變.
• 拖圖題全出資題庫.

• 實驗題考了題庫中的ACL-1,ACL-3,OSPF,全原題,題目順序,選項順序均與題庫相同,另外有一個EIGRP的選擇題,不要死記答案,實驗題按步給分

  EIGRP詳情:

  Question 1

  The loopback interfaces on R4 with the IP addresses of 10.4.4.4/32,10.4.4.5/32 and 10.4.4.6/32 are not appearing in the routing table of R5. Why are the interfaces missing?

  A. The interfaces are shutdown, so they are not being advertised.
  B. R4 has been incorrectly configured to be in another AS, so it does not peer with R5.
  C. Automatic summarization is enabled, so only the 10.0.0.0 network is displayed.
  D. The loopback addresses haven’t been advertised, and the network command is missing on R4.

  在考試中show run查到R4沒有宣告它的環回地址,也就是選D

  Question 2

  Which path does traffic take from R1 to R5?

  A. The traffic goes through R2.
  B. The traffic goes through R3.
  C. The traffic is equally load-balanced over R2 and R3.
  D. The traffic is unequally load-balanced over R2 and R3.

  在考試中查看到R2，R3這兩條的路徑都是等值的，所以選C.

  Question 3

  Router R6 does not form an EIGRP neighbor relationship correctly with router R1. What is the cause for this misconfiguration?

  A. The K values mismatch.
  B. The AS does not match.
  C. The network command is missing.
  D. The passive-interface command is enabled.

  考試中在config模式下輸入 show ip protocol 會看出R6和R1的k值不相同,即選擇A,”The K values mismatch.”

  Question 4

  R1爲什麼ping不通R5？

  A. The network statement is missing on R5.
  B. The loopback interface is shut down on R5.
  C. The network statement is missing on R1.
  D. The IP address that is configured on the Lo1 interface on R5 is incorrect.

  考試查看兩路由器配置,答案是R5沒有10.5.5.55宣告進EIGRP，選A

個人經驗

一開始還是主張學技術爲主,”CCNA學習指南”那本書講的還行,但是有些東西還是有點模糊,比如廣域網那裏,建議還是看看視頻.

還有一些200-120的新考點
(包括SNMP、Netflow、HSRP、VRRP、GLBP)書上並沒有涉及,還是需要自己善用搜索:

• SNMP:http://bbs.hh010.com/forum.php?mod=viewthread&tid=381124&highlight=SNMP
• Netflow:http://bbs.hh010.com/thread-381122-1-1.html
• HSRP,VRBP,GLBP:http://bbs.hh010.com/forum.php?mod=viewthread&tid=29175&highlight=hsrp

考前的一個星期可以看題庫了,前幾天可以一天50題的練,順帶看看講解視頻.到後面熟了量慢慢加,考前一天再刷一遍題,過應該是沒問題了.重點說下題庫裏的關於trap的問題

Question 248

What level will be trapped if the administrator executes the command (choose four)

router(cfg)#logging trap 4
A. Emergency
B. Notice
C. Alert
D. Error
E. Warning

Correct Answer:ACDE

Question 253

Syslog was configured with a level 3 trap.Which 3 types of logs would be generated(choose three)

A. Emergencies
B. Alerts
C. Critical
D. Errors
E. Warnings

Correct Answer:ABC(注意答案有問題)

Question 262

A network administrator enters the following command on a router:logging trap 3.
What are three message types that will be sent to Syslog server?(choose three)
A. informational
B. emergency
C. warning
D. critical
E. debug
F. error

Correct Answer:BDF

syslog 將內容分爲七個級別：Emergency，Alert，Critical，Error，Warning，Notice，Info，Debug,優先級從0到7,這樣細心的同學可以看出Q253不止一個答案,沒錯!還可以選ABD,BCD等.所以要注意下,不要死背答案.

考試當天帶好兩證,提前30min進考場.然後服務人員會幫你辦理相關手續(會讓你拍個照片,籤個字什麼的).
之後你就可以進去考了,一開始時會有幾個選擇年齡,同意思科條款之類的.接着有指導教程,沒考過思科的朋友推薦還是耐心看完,這個不計入考試時間的,後面操作會省下很多時間.接着做完50多題,結束考試.之後就會出現一些關於考試本身意見的調查,這個隨便選選無所謂的.

考完之後會打印你的成績單,過會應該就能收到註冊郵件了.

題外話

很多人說CCNA沒有用,個人感覺還是能學到很多知識的.自學完這個再聽學校的網絡課程,真的感覺學校講的好淺.所以說,NA主要還是幫助我們掌握一些基本的網絡知識,培養興趣.
