A critical server was replaced by the IT staff the previous night. The following morning, some users are reporting that they are unable to browse to the Internet upon booting their workstations. Users who did not shut down their workstations the previous day are able to connect to the Internet. A technician looks at the following report from a workstation with no Internet connectivity: IP Address: 192.168.1.101, Netmask: 255.255.255.0, DHCP Server:192.168.1.1, DNS Server:192.168.1.2, Default Gateway:192.168.1.1, Given the above report, which of the following is the cause of why some workstations are unable to browse the Internet?
The DHCP server is misconfigured
The workstation has an APIPA address
The DHCP server is unavailable
The default gateway router is misconfigured
Correct Incorrect Unanswered
Answer Description
If the DHCP Server was down users would receive APIPA Addresses, which is not the case. However, because only computers that have been restarted are affected, we can still assume it is a DHCP Problem, most likely a configuration issue.

The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client–server architecture.The technology eliminates the need for individually configuring network devices manually, and consists of two network components, a centrally installed network DHCP server and client instances of the protocol stack on each computer or device. When connected to the network, and periodically thereafter, a client requests a set of parameters from the server using DHCP.
DHCP can be implemented on networks ranging in size from residential networks to large campus networks and regional ISP networks. Many routers and residential gateways have DHCP server capability. Most residential network routers receive a unique IP address within the ISP network. Within a local network, a DHCP server assigns a local IP address to each device.
DHCP services exist for networks running Internet Protocol version 4 (IPv4), as well as version 6 (IPv6). The IPv6 version of the DHCP protocol is commonly called DHCPv6.
