Which generation of cellular digital communications standards is supposed to deliver a minimum of 100 Mbps for access from moving users?
5G
[5G is supposed to deliver a minimum of 100 Mbps for access from a fast-moving vehicle and 1 Gbps for stationary users. Speeds of up to 70 Gbps have been achieved under test conditions.]
You are shopping for a new tablet. You are hoping to make a purchase that includes a stylus pen. Which of the following satisfies the stylus requirement of touch sensitivity.
Active
[An active stylus includes electronics within the stylus that enable features, such as menu options via buttons on the stylus, and touch sensitivity. A tablet would need to support an active stylus in order for one to be used with it.]
Which type of server can be used to dynamically assign Internet Protocol (IP) addresses and subnet masks?
DHCP server
[See also stores a pool of IP addresses]
Which bus slot provides the highest video performance?
PCIe
[Peripheral Component Interconnect Express (PCIe) offers the highest video performance. A PCIe x16 version 3 card can transfer a maximum of 16 gigabyte per second (GB/s). Compare this to the closest competitor listed: Accelerated Graphics Port (AGP), which can do 2,133 megabyte per second (MB/s), about 1/8 of PCIe.]
How can you verify whether a solution you apply fixes a problem?
Substitute the part for a "known good" one.
[Makes no sense. Something stupid to memorize and watch out for!]
Which of these is NOT necessary when troubleshooting display configuration issues?
Fixing dead pixels
[Many display problems are caused by errors in configuration, but you must also be alert to the possibility of hardware faults in the monitor itself, such as dead pixels.]
You have a single user who cannot connect to the Internet, but the user can connect to all internal servers, printers, and internal web servers. What should you check as the probable cause?
Check the user's browser's proxy settings.
[User does not need creds to use Router, so it is likely the Proxy Server settings.]
Which of the following Hypervisors is included with Windows 10 Professional?
Hyper-V
[Hyper-V is a type-1 hypervisor that is included with Windows 10 Professional. A type-1 hypervisor has direct communication with the system’s physical hardware.]
You do not want the guest virtual machines to be able to communicate with any other physical system on the network: however, communication between the guests and the hosts is allowed. Which type of virtual switch should you create in Hyper-V?
Internal
[Compare this to "Private": Only used by Guest and nothing else]
A support ticket has been assigned to you stating that the Engineers are complaining that their Computer Aided Design (CAD) application is displaying poorly. What do you do to upgrade these PCs and solve this problem?
Install higher-end video cards.
[The goal is to improve display not processing]
Which of the following Intel CPUs are laptop only chips?
Core Duo
[This was also true of Core Solo]
Which statement is NOT correct about 32-bit and 64-bit Central Processing Units (CPUs)?
A: Maximum memory supported is over 4GB using a 64-bit processor.
B:A 32-bit processor is adequate for any program written for a 32-bit processor.
C: More computers are built using 32-bit processors
D: Software programs requiring many calculations operate faster on 64-bit processors.
C: More computers are built using 32-bit processors
[Computer parts retailers are offering fewer and fewer 32-bit processors and soon may not offer any at all.]
You need to configure a SOHO (Small Office Home Office) network to provide Internet Protocol (IP) Addresses only to devices allowed on the network. You have configured a list of devices that are allowed to access the network. Which feature should be enabled?
MAC (Media Access Control) Filtering
[MAC (Media Access Control) Filtering refers to a security access control method whereby the MAC address, unique to each network card, is used to determine access to the network. IP addresses are assigned to network devices.]
Which DVI (Digital Visual Interface) configuration has a bandwidth of 7.4 Gbps (Gigabits per second)?
DVI-D dual link
[The Dual Link provides greater bandwith]
The 802.11ac standard is one of five Wi-Fi standards and supports up to 8 spatial streams of data. At what speed and on what radio frequency does the 802.11ac operate?
Speeds up to 1.7 Gbps in the 5 GHz band
[The 802.11ac standard provides high-throughput wireless local area networks only in the 5 GHz band. At speeds as high as 1.7 Gbps now, it aims to get throughput like that of Gigabit Ethernet or better.]
