What is the nominal data rate of a USB port supporting Gen 3.2 2x1?
Ans: 10 Gbps.
"You are configuring four 120 GB drives in a RAID 5 array. How much space will be
available?"
Ans: 360 GB.
What is the bandwidth of a PCIe v2.0 x16 graphics adapter?
Ans: 8 GBps in each direction (full-duplex). PCIe v2 supports 500 MBps per lane.
You need to connect permanent cable to the back of a patch panel. Which
networking tool might help you?
Ans: A cable stripper to remove the jacket insulation and a punchdown tool to
terminate the wire pairs into insulation displacement connector (IDC) blocks.
Why can cache improve performance?
Ans: A CPU tends to repeat the same routines and access the same data over and
over again. If these routines are stored in fast cache RAM, they can be accessed more
quickly than instructions and data stored in system memory.

You receive a support call from a user of one of the company's computer-aided
design (CAD) workstations. The user reports that a notification "RAID utility reports
that the volume is degraded" is being displayed. A recent backup has been made.
What should you do to try to restore the array?
Ans: "A degraded volume is still working but has lost one of its disks. In most RAID
configurations, another disk failure would cause the volume to fail, so you should
add a new disk as soon as possible (though do note that rebuilding the array will
reduce performance)."
"You receive a support call from a lecturer. A projector is only displaying a very dim
image. Which component should you prioritize for investigation?"
Ans: "A dim image is likely to be caused by a blown bulb (or one that is about to
blow). If there is no visible sign of damage to the bulb, you should rule out a simple
configuration issue, such as the brightness control being turned all the way down."
A network owner has configured three web servers to host a website. What device
can be deployed to allow them to work together to service client requests more
quickly?
Ans: A load balancer.
"What is the main security requirement of a virtualization workstation configured to
operate VMs within a sandbox?"
pg. 2
, March 25
Ans: "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)."
"A network uses Fiber Channel adapters to implement connections. What type of
network is this?"
Ans: 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?"
Ans: "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?"
Ans: "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?
pg. 3
, March 25
Ans: 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?
Ans: 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?"
Ans: 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?
Ans: 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?"
Ans: An IPv6 address.
