A user needs to connect their laptop to the wired Ethernet network, but
the laptop does not have an integrated Ethernet interface. Which of the
following would allow the laptop to connect to an Ethernet network?
(Pick TWO)
❍ A. Docking station
❍ B. VGA interface
❍ C. USB to Ethernet adapter
❍ D. DisplayPort to HDMI cable
❍ E. DVI to HDMI adapter
❍ F. Bluetooth
The Answer: A. Docking station
C. USB to Ethernet adapter
There are a few ways to create a wired Ethernet connection on a laptop
computer. Using a docking station is a common solution that provides
many different interfaces, and often includes the ability to install a full-
size PCI Express (Peripheral Component Interconnect Express) adapter.
A USB (Universal Serial Bus) to Ethernet adapter is a simpler solution that
only provides an Ethernet interface, but it's much more portable than a
docking station.
,A server administrator has received an alert showing that one drive in a
RAID 1 array has failed. Which of the following would be the best way
to resolve this alert?
❍ A. Replace the bad drive and resync the array
❍ B. Replace all drives in the array and resync the array
❍ C. Replace the bad drive and restore from backup
❍ D. Convert the array to RAID 0 and replace the drive
❍ E. Replace all drives in the array and restore from backup
The Answer: A. Replace the bad drive and resync the array
A RAID 1 (Redundant Array of Independent Disks, level 1) array is a
mirrored array, which means that all of the information on one physical
drive is also copied and maintained on a separate drive. If one drive fails,
then the drive with the redundant data continues to be available. To
repair the array, the bad drive needs to be replaced and the data from
the
redundant drive is synchronized to the new drive.
A system administrator is building a server for a data center in another
country. The server will manage a print queue and provide a local
storage partition for temporary file transfers. Which of the following
power supply specifications will be the MOST important for this server?
❍ A. Voltage input options
❍ B. Number of PCIe connectors
❍ C. Modular cabling
❍ D. Fan noise rating
The Answer: A. Voltage input options
Connecting to the power source in a different country is an important
consideration when selecting a power supply. If the voltage
specifications
are incorrect, the server may not operate at all or components in the
server may be damaged. Many servers use auto-switching power
supplies are compatible with the power systems in other countries.
,Which of the following ports are used for file transfers? (Select TWO)
❍ A. 21
❍ B. 110
❍ C. 25
❍ D. 23
❍ E. 20
❍ F. 53
The Answer: A. 21 and E. 20
FTP (File Transfer Protocol) is a standard method of transferring files
across different operating systems. FTP uses TCP (Transmission Control
Protocol) port 21 for control messages and port 20 to transfer data.
Which of these technologies do not require a backlight to provide a
viewable display?
❍ A. LCD
❍ B. IPS
❍ C. OLED
❍ D. LED
The Answer: C. OLED
An OLED (Organic Light Emitting Diode) display emits light when a
current is provided to an organic compound, so a backlight would not be
necessary with an OLED display.
, A system administrator has tripped over an Ethernet cable and the cable's
RJ45 connector has broken. Which of the following should be used to
resolve this issue?
❍ A. Punch-down tool
❍ B. Tone generator and probe
❍ C. Cable tester
❍ D. Crimper
The Answer: D. Crimper
A crimper is used to attach a modular connector to a cable. In this
example, a new connector can be reattached to the cable using an RJ45
(Registered Jack type 45) crimper.
A network administrator is troubleshooting a network outage, and she
believes that the issue is related to a bad switch. The old switch is
replaced with a newer model and the cabling is moved to the new switch.
Which of the following should be the NEXT troubleshooting steps?
(Choose TWO)
❍ A. Test the theory
❍ B. Verify full system functionality
❍ C. Establish a plan of action
❍ D. Identify the problem
❍ E. Document the findings
The Answers: B. Verify full system functionality, and
E. Document the findings
Once the theory has been tested, a plan of action has been determined,
and the plan has been implemented, it's important to verify that full
system functionality has been restored. After all of this work, it's useful to
document the problem, the proposed solutions, and the ultimate fix. This
problem might occur again, and it would be useful to have some
historical documentation on how to address the issue.
