text : 'If mask 255.255.255.128 were used with a Class B network, how many subnets could exist, with how many hosts per subnet, respectively?',

responses : [
'256 and 256.',
'254 and 254.',
'62 and 1022.',

answer : 4,
score : 1,
expandedAnswer : 'Class B networks imply 16 network bits; the mask implies 7 host bits (7 binary 0s in the mask), leaving 9 subnet bits. 2^9 yields 512 subnets, and 2^7 - 2 yields 126 hosts per subnet.',

'The ip address dhcp command.',
'The interface vlan 1 command.'

answer : 0,
score : 1,
expandedAnswer : 'Both switches and routers configure IP addresses, so the ip address address mask and the ip address dhcp commands could be used on both routers and switches. The interface vlan 1 command applies only to switches.',
