What is the main security requirement of a virtualization workstation configured to
operate VMs within a sandbox? - ✔✔A sandbox means that the VM environment
should be isolated from the host and from other VM environments. A sandbox is often
used to investigate malware. If the sandbox is secure, the malware can be executed and
observed without the risk of it spreading to other systems (VM escaping).
Accessed by only servers, a network uses Fiber Channel adapters to implement
connections. What type of network is this? - ✔✔A Storage area network (SAN),
A host is configured with the IP address 172.16.1.100 in the 172.16.1.0/16 IP network.
What value should be entered as the subnet mask? - ✔✔A subnet mask field uses
dotted decimal format. The /16 network prefix means that the first 16 bits in the mask
are set to one: 11111111 11111111 00000000 00000000. A whole octet of ones
converts to 255 in decimal. Therefore, the dotted decimal mask is 255.255.0.0.
You are recommending that a small business owner replace separate firewall and
antimalware appliances with a UTM. What is the principal advantage of doing this? -
✔✔A unified threat management (UTM) appliance consolidates the configuration,
monitoring, and reporting of multiple security functions to a single console or
dashboard. You might also mention that the UTM might provide additional functionality
not currently available, such as intrusion detection, spam filtering, or data loss
prevention.
Why must a vendor account usually be configured on a smartphone? - ✔✔A vendor
account, such as an Apple, Google, or Samsung account, is required to use the app
store.
,What type of network has no specific geographical restrictions? - ✔✔A wide area
network (WAN) can span any geographical distance.
A network uses an IEEE 802.11 standard to establish connections. What type of network
is this? - ✔✔A wireless local area network (WLAN).
Following some past issues with faults arising in print devices because of improper setup
procedures, you are updating the company's work instructions for printer installation.
You have noted that technicians must refer to the product instructions, use safe lifting
techniques, and ensure removal of packing strips. What additional guidance should you
include? - ✔✔Allow the print device to acclimate for a few hours after unboxing to
avoid risks from condensation.
What type of value would you expect a query for an AAAA resource record to return? -
✔✔An IPv6 address.
You are assisting another customer with a full fiber connection terminated to an optical
network terminal (ONT). The customer's router was disconnected while some building
work was being completed, and the patch cable is now missing. The customer thinks
that the cable should be a fiber optic one because the service is "full fiber." What type
of cable do you need to locate? - ✔✔An RJ45 unshielded twisted pair (UTP) patch
cable. The ONT converts the optical signal over the external fiber optic cable to an
electrical one to connect to the local router.
A company has contracted the use of a remote datacenter to offer exclusive access to
platform as a service resources to its internal business users. How would such a cloud
solution be classed? - ✔✔As a private deployment model.
What cause might you suspect if a PC experiences intermittent lockups? -
✔✔Assuming the cause is not related to software or device drivers, then thermal or
,power problems are most likely. Loose connections, faulty system components
(motherboard, CPU, and memory), and corruption of OS files due to bad sectors/blocks
are also possibilities.
You are setting up an ADSL router/modem for a client; unfortunately, the contents of
the box have become scattered. What type of cable do you need to locate to connect
the router's WAN interface? - ✔✔Asymmetrical Digital Subscriber Line (DSL) connects
to the phone line via a filter. You need an RJ11-terminated patch cord to make the
connection.
A laptop user reports that they are only getting about two hours of use out of the
battery compared to about three hours when the laptop was first supplied to them.
What do you suggest? - ✔✔Batteries lose maximum charge over time. It may be
possible to recondition the battery or to use power-saving features, but the only real
way to restore maximum battery life is to buy a new battery.
A technician connects a single port on a graphics card to two monitors using two cables.
What type of interface is being used? - ✔✔Both DisplayPort and Thunderbolt
interfaces support this type of daisy-chaining.
You are performing a wiring job, but the company wants to purchase the media and
components from another preferred supplier. The plan is to install a network using
copper cabling that will support Gigabit Ethernet. The customer is about to purchase Cat
5e cable spools. What factors should they consider before committing to this decision? -
✔✔Cat5e will meet the requirement and will cost the least. Cat 6 offers better
performance without adding too much cost. Cat 6A would be the best choice for
supporting future requirements, but it is likely to cost more than the customer is
budgeting for.
You are trying to install Windows from the setup disc, but the computer will not boot
from the DVD. What should you do? - ✔✔Check that the boot order in system setup
is set correctly. If the boot order is correct, check that the disc is not dirty or scratched.
, If the disc loads in another computer, check that the optical drive data and power cables
are connected.
How would you track down the source of a paper jam? - ✔✔Check the error message
reported by the printer (this may be shown on the printer's console). It may indicate the
location of the stuck pages. Otherwise, visually inspect the various feed and output
mechanisms.
You are configuring a different workstation with dual-channel memory. You have two
modules and there are four slots. How would you determine which slots to use? -
✔✔Check the vendor's setup/service manual. Many systems will use the slots
marked A1 and B1, but it's best not to proceed without consulting the vendor's
documentation.
You are writing a knowledge base article for remote staff members who need to use
their smartphones to provide Internet connectivity to their laptops. Two options to
facilitate this include configuring a hotspot or the use of tethering. What distinguishes
the two options? - ✔✔Configuring a hotspot allows the laptop to connect to the
smartphone over Wi-Fi. Tethering means connecting the laptop via USB or Bluetooth.
Which types of data might require mapping between fields when syncing between
applications? - ✔✔Contacts and calendar items.
If print jobs do not appear at the printer and the queue is clear, what could you try first
to solve the problem? - ✔✔Cycle the power on the printer.
A user reports that there is a loud clicking noise when she tries to save a file. What
should be your first troubleshooting step? - ✔✔Determine whether a data backup
has been made. If not, try to make one.
