原题图
B. The link is addressed on the *zero*subnet 10.0.0.0 network.(由于运行ip subnet zero命令,接口 10.0.1.1/24的网络ID是10.0.0.0/24,因此B是正确的)
C. The link uses a three-way handshake for authentication.(CHAP-Chanllege Handshake Authentication Protocol, three-way protocol)
D. The link uses a two-way handshake for authentication.
E. Data exchanges between the Oriando and Tampa routers are encrypted.(CHAP是一种加密的验证方式,能够避免建立连接时传送用户的真实密码,不是加密数据的)
