You work as the network administrator at CERT killer .com. You install a VLAN on the Certkiller .com network to create two subnets. However, users on one subnet cannot access servers on the other subnet. What should you do to resolve this problem?
A. Install a router between the two subnets. B. Install a DHCP server in each subnet. C. Install a proxy server in each subnet. D. Install a DNS server in each subnet.
Install a router between the two subnets.-to forward traffic between two subnets, we would need a router.incorrect answers:b: a dhcp server is used to automatically assign tcp/ip configurations to hosts on a network. installing a dhcp server in each subnet will ensure that hosts on each subnet will have the proper ip configurations. however, the problem here is that a router is required to forward traffic between two subnets.c: a proxy server is used to protect a network from attacker on the internet. it is not used to forward traffic between subnets.d: a dns server is used for host name to ip address resolution. it is not used to forward traffic between subnets.reference:david groth and toby skandier, network+ study guide (4th edition), sybex, alameda ca, 2005, pp. 134-13, 142-144, 153-154.
