A foul or chemical odor—especially one that isn’t a traditional burning smell—often signals leaking or swollen capacitors, which are located on the motherboard. Visually inspecting for distended or bulging capacitors is critical, and a failure typically means the motherboard must be replaced.
You are working as part of a PC Refresh Team installing 150 Desktop Computers in Dion Training’s New Offices. When you boot up the 72nd Desktop you installed, you smell a foul-smelling chemical odor. You sniff the air again and confirm the smell isn’t a burning smell. Upon opening the case, which component should you inspect for damage and expect to replace?

Dion Training’s Service Desk has received calls from numerous users stating they are receiving an error message concerning duplicate IP Addresses being detected on their Systems. These users also cannot access the Network’s File Server or browse any Websites. Which of the following Servers should the technician check first in troubleshooting this issue? Proxy Server | DHCP Server EXPLANATION: A Domain Name System (DNS) Server is a Server that hosts the database of Domain Names and the IP Addresses mapped to those names. Each DNS Server is authoritative for certain Domain Names that their org owns. A Proxy Server is a Server that acts as an intermediary between a client requesting a Resource and the Server that provides that Resource. A Proxy Server can be used to Filter Contents and Websites from Reaching a User. An Authentication, Authorization, and Accounting (AAA) Server is a server used to identify (Authenticate), Approve (Authorize) and keep track of (Account For) users and their Actions. AAA Servers can also be classified based on the Protocol they use such as a RADIUS Server or a TACACS+ Server. |

Jason is Teaching a CompTIA Course at a large company, but they do not allow non-employees to connect to their Network. Since Jason needs the Internet for an in class demonstration, he connects his laptop to his iPhone over WIFI and essentially connects to the Internet using the Smartphone as a Modem. Which of the following terms best describes this Configuration? Tunneling | Hotspot EXPLANATION: Tethering uses the Cellular Data Plan of a Mobile Device to provide Internet Access to a Laptop or PC. The PC can be Tethered to the Mobile by USB, Bluetooth, or WIFI (A Mobile Hotspot). One method of doing this is to connect the laptop to the device using a WIFI connection and routing all of your data from your laptop to the phone over WIFI and then from the phone to the Internet using the phone’s built-in Cellular Modem. Tunneling (Or Encapsulation) Protocol wraps up data from one protocol to transfer over a different type of Network. For example, PPP can carry TCP/IP data over a Dial-Up Line enabling a remote computer to communicate with the LAN. A Baseband Update is the modification of the firmware of a Cellular Modem. |
Virtual Machine | Emulator EXPLANATION: Virtual Machines use CPU Self-Virtualization, to whatever extent it exists, to provide a Virtual interface to the real hardware. A Simulator is a limited scope that is usually used in training to mimic a real system’s functionality. Emulators were created before Virtualization and operate much slower than a True Virtualization environment with a Hypervisor. |
11” x 9.6” | 9.6” x 9.6” EXPLANATION: The mATX (MicroATX) Motherboard's form factor is 9.6" x 9.6" in size (24 cm x 24cm). The mATX Form Factor is commonly used in smaller computer systems with a small form factor (SFF) case.
