You are the network administrator for a small consulting firm. The office network consists of 30 computers, one server, two network printers, and a switch. Due to security concerns, there is no wireless network available in the office. One of your users, Bob, travels to client sites and is generally not in the office. When Bob goes to client sites, he typically just connects to their wireless networks. When he's in the office, Bob connects his laptop to the network with an Ethernet cable. You need to make sure that Bob's laptop is setup so that when he plugs the Ethernet cable into his laptop, no further configuration is needed. Which of the following would be the BEST option to achieve this?
Configure an alternate IP configuration.

You've configured your organization's DHCP server to dynamically assign IP addresses and changed the default lease time from eight to four days. What impact, if any, will this have on the network?
Increased network traffic
Which of the following statements about Dynamic Host Configuration Protocol (DHCP) are true? (Select two.)
It can deliver other configuration information in addition to IP addresses. A DHCP server assigns addresses to requesting hosts.
CorpServ is a small company with 14 client systems and a network printer. Because there are only a limited number of network systems, you decide to use APIPA addressing. With APIPA configured, all the systems are able to communicate with each other, but you're having trouble configuring internet access. What is the MOST LIKELY cause of the problem?
Private addresses cannot directly communicate with hosts outside the local subnet.
You are the network administrator for a large hospital. One of your users, Suzie, calls you stating that she is unable to access any network resources. After some initial troubleshooting, you realize that her computer is using the IP address 169.254.0.52. You've confirmed that the network's physical connection is connected properly. Which of the following should you do next?
Renew the IP address.
Which of the following DHCP scope options assigns a static IP configuration to a device using that device's MAC address?

Subnets divide an IP network address into multiple network addresses.
You are the network administrator for a small consulting firm. Users are complaining that they are unable to reach network resources. After some troubleshooting, you've confirmed that the DHCP server is down.

Which of the following is the MOST likely reason the devices are not receiving their APIPA addresses?
The DHCP lease has not expired.
You are the network administrator for a large hospital. One of your users, Suzie, calls you stating that she is unable to access any network resources.

Due to wide network expansion, you've decided to upgrade your network by configuring a DHCP server. The network uses Linux, Windows, and Mac OS X client systems. You configure the server to distribute IP addresses from 192.168.2.1 to 192.168.2.100. You use the subnet mask of 255.255.255.0. After you make all the setting changes on the DHCP server, you reboot each client system, but they are not able to obtain an IP address from the DHCP server. Which of the following explains the failure?
You must configure the clients to obtain IP addressing from a DHCP server.
