2019.11.29 300-101 青岛 851 PASS

本人公司网管，接触思科设备十年了，平时思科交换的经验多，路由的经验少。
这次np先是9月份过了tt,上周五29号过了路由851分。
: h, [" V( P" O+ i  V周末要陪老婆孩子，工作日每天学习大约一两小时，刚开始准备一边看题库一边看论坛里的路由的视频，后来发现看视频太慢，会影响整体进度可能导致明年考不完交换，就专攻题库了。看的是精简版，年过不惑精力不济，晚上有时看着看着睡过去，有的题目记不住，只能去了解理论知识加深记忆。最后选择题自测每次正确率90%以上，每道实验题都做了四五遍。因为要留出时间给交换，所以计划必须11月完成路由，考前一周看了一遍完整版题库，没怎么记住，怀着忐忑不安的心情走进考场，幸好过了。
8 r" Q8 X- o2 V! U考题共55道，3道实验题，OSPF，EIGRP Case，OSPF IPv6，最后这道题题目要求把所有不正确的配置都改正，改正越多得分越多，我按题库答案新加了R2-R3的virtual-link, 去掉了R3-R4的virtual-link，R1上有了R4环回(FEC0:4:4)的路由，满足了题目要求，但是R4上没有R1的路由，R2R3上都有R1的路由，不知道什么原因，可能扣分了。
. T& [! o- l9 o! |6 b5 C拖图题2道，都是题库里的。
选择题有几道拿不准：
1，问route map的名字是不是case-sensitive, 我选了是，貌似其他选项也不错。不在题库内。
2，QUESTION 159

( |5 f) s4 O3 P5 M* b0 ZWhich two protocols can be affected by MPP? (Choose two)
A. POP B. SMTP C. HTTP D. SFTP E. SSH
Answer: C E
Explanation
The Management Plane Protection (MPP) feature in Cisco IOS software provides the capability to restrict the interfaces on which network management packets are allowed to enter a device. The MPP feature allows a network operator to designate one or more router interfaces as management interfaces. Device management traffic is permitted to enter a device only through these management interfaces. After MPP is enabled, no interfaces except designated management interfaces will accept network management traffic destined to the device.
In the command management-interface interface allow protocols we can configure these protocols (to allow on the designated management interface):
. b+ ^, t: C9 v/ V& X' B+ BEEP + FTP + HTTP + HTTPS + SSH, v1 and v2 + SNMP, all versions + Telnet + TFTP
Therefore these are also the protocols that can be affected by MPP.
