- 1Difference between ONT and OLT?ONT = Optical Network Terminal. Installed at customer's premises, connects to router through RJ45 patch cord
OLT = Optical Line Terminal, located in street cabinet, connects to to ONTs via fiber - 2What causes "chip creep?"Changing temperatures and dust and dirt infiltration.
- 3Difference between Printer Properties and Printer Preferences?Printer Properties addresses the underlying hardware.
Printer Preferences address the print jobs themselves. - 4What are the most likely causes for hard disk drive extended read and write times?Bad sectors or bad blocks, which themselves are groups of sectors.
- 5Storage devices listed from slowest and least volatile to fastest and most volatile?USB Stick, 2.5" HDD, mSATA SSD, RAM, CPU cache.
- 6Explain differences between Single-mode fiber and multi-mode fiber.Single-mode fiber: small core, carries long wavelength over long distances.
Multi-mode has a larger core and carries short wavelength over shorter distances. - 7Difference between dBi and dBm?dBi = decibels isotropic, measures antenna gain
dBm = decibel milliwatts, measures transmit power. - 8What is the LDAP protocol?Lightweight Directory Access Protocol = a TCP/IP protocol used to query and update resources in a directory, such as Windows Active Directory
- 9What P1 motherboard connector is most common these days?A 20+4-pin adapter cable for compatibility with older motherboards with a 20-pin port.
- 10Difference between DVI-I, DVI-D and DVI-A?DVI-I = connects digital source to analog display, such as VGA, or analog source to digital display.
DVI-D = connects digital devices.
DVI-A = connects analog devices. - 11What needs cleaning or replacing if every print job has lines of toner in the same location on every page?The drum.
- 12What allows the usage of RAM sticks with different capacities?Flex mode.
- 13A flickering image could also be caused by the display's backlight or what other component starting to fail?Circuitry.
- 14What are the possible causes of port flapping?The ethernet cable, the NIC port, or the switch port.
- 15When troubleshooting, what are the three items that define a problem?Symptoms, cause, consequence.
- 16What can cause port flapping on a network switch?Bad cabling, a faulty port, or interference.
- 17Define RAID types.RAID 0 : Striping, no parity
RAID 1: mirrored disks
RAID 5: Striping with parity, requires at least 3 disks
RAID 10: Striping and mirroring, requires at least four disks - 18What type of storage devices interfaces directly with a PCI Express bus?M.2 drives.
- 19If a laser printer is malfunctioning at the exposing stage, what is happening?The imaging drum is not properly losing charge after it is applied by the Primary Charge Roller (PCR).
- 20What steps would you take to troubleshoot a distortedly large image?Check the video card configuration, and update the video card driver.
- 21If your original solution didn't work, what should you do?Either develop a new theory, or escalate the problem.
- 22Difference between cloud computing and Software as a Service?Cloud computing provides on-demand resources over a network, while SaaS is a model of provisioning software apps in a pay-as-you-go arrangement.
