在Linux系统中搭建DHCP服务器时，若需要给客户机指定默认网关地址为192.168.1.1,可以在dhcpd.con僧己置文件中进行 A: option default-gate-way 192.168.1.1 B: option gateways 192.168.1.1 C: option routers 192.168.1.1 D: option router-servers 192.168.1.1

192.168.1.1属于（）类ip地址

要在一个接口上配置 IP地址和子网掩码，下列命令正确的是？ A: Switch（config） B: ip address 192.168.1.1 C: Switch （config-if ） D: ip address 192.168.1.1 E: Switch （config-if ） F: ip address 192.168.1.1 255.255.255.0 G: Switch（config-if ） H: ip address 192.168.1.1 netmask 255.255.255.0

When scaling Coherence from one to two cache servers， it will not show the same scalability as two to four. Why？（） A:  Coherence uses a more efficient TCMP algorithm going from two to four cache servers B:  When going from one to two cache servers， object backups are copied across servers so work is doubled，but going from two to four is a fixed amount of work C:  Near cache is enabled with a larger quorum thus performance is improved D:  all of the above

When scaling Coherence from one to two cache servers， it will not show the same scalability as two to four. Why？（） A: A Coherence uses a more efficient TCMP algorithm going from two to four cache servers B: B When going from one to two cache servers， object backups are copied across servers so work is doubled，but going from two to four is a fixed amount of work C: C Near cache is enabled with a larger quorum thus performance is improved D: D all of the above

Which of the following should be done FIRST before installing NOS patches in a productionenvironment？（） A: Install patches on non critical servers B: Install patches in test environment C: Install patches on a PC D: Install patches on critical servers

设置默认路由为192.168.1.1的命令是__________

192.168.1.1是正确的IP地址表示形式。

IP地址192.168.1.1是C类私有地址。
