Question 1:  Correct While setting up a home office, a technician disables the DHCP service on the office router, but does not want to rely on link-local addressing. Which of the following IP addressing methods should be used? EXPLANATION Without DCHP, many network hosts assign their own non-routable link-local IP address. To avoid linklocal addresses when DHCP addressing is unavailable, static addresses should be assigned to all devices that will communicate on the local network. Dynamic addressing automatically assigns IP addresses using DHCP. Automatic Private IP Addressing (APIPA) is Microsoft's name for auto-configuring link-local addresses. Alternate IP addressing is a way to assign a second IP address to a host.

EXPLANATION A laser printer uses lasers and electrical charges to transfer images to paper. A thermal inkjet printer applies heat to the ink in print head nozzles, causing the ink to boil and expel itself from the nozzle. A piezoelectric printer uses pressure, not heat, to apply the ink. A dot matrix printer uses pins striking the ink ribbon to transfer the ink.

You connect a workstation to the 192.168.1.0 subnet, which uses the default subnet mask. This workstation can communicate with some hosts on the private network, but not with other hosts. You run ipconfig /all and see the following: Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . : Broadcom network adapter Physical Address. . . . . . : 00-AA-BB-CC-74-EF DHCP Enabled . . . . . . . : No Autoconfiguration Enabled. . . : Yes IPv4 Address . . . . . . . : 192.168.1.102(Preferred) Subnet Mask. . . . . . . . : 255.255.0.0 Default Gateway . . . . . . : 192.168.1.1 DNS Servers . . . . . . . : 192.168.1.20 192.168.1.27 Which of the following is the MOST likely cause of the problem? EXPLANATION In this example, the network is using a mask of 255.255.255.0 (24-bits), but the workstation is configured to use a mask of 255.255.0.0.

EXPLANATION Parity error detection can only detect errors with only one bit, while Error Correcting Code (ECC) can detect errors with more than one bit. EDO is not a type of error correction, it is a type of memory that can start a new access cycle while keeping the data output of the previous cycle active.
