1、Inwhich order of magnitude (time) is delay/latency measured when you use widemetrics in EIGRP?

A. tens of microseconds

这题应该选A还是选B 找了俩个题库，看到都是选B 但是查资料都没找到picoseconds这个单位，就只看到个tens of microseconds。

2、Which two values are required to implement anEIGRP named configurations? (Choose two)

A. address-family

B. process-id

114. Which technology can be used to secure the edge of an STP domain?
A. root guard
B. BPDU guard
C. UplinkFast
D. BPDU filter
为啥这道题选B，不选D呢。难道BPDU filter不更安全些吗。在俩个同时配置的情况下 BPDU guard不是会失效吗、？
