You want to install three virtual Linux workstations on your Windows Pro machine. Each Linux install requires 2GB of available system memory. Including the Virtual Machine Manager (VMM), what is the minimum amount of installed system memory needed to accomplish this?
4GB
8GB
10GB
16GB
Explanation: Each Virtual machine will require 2GB of RAM for installation and your OS requires 4GB. This makes your resource requirement 10GB. The VMM is considered part of the OS and does not create any additional resource requirements.

Correct answer: 10GB
You are adding virtual machine support to an Intel-based Windows PC. In addition to the obvious memory and space requirements what else may need to be configured or enabled?
AMD-V
Hyper-V
VT
I-Vs
Explanation: On an Intel-based platform, Intel’s VT (Virtualization Technology) or VT-x hardware acceleration must be enabled in BIOS/UEFI to support virtualization. On AMD platforms AMD-V would need to be enabled. Consider that if Microsoft’s optional feature Hyper-V is enabled, your 3rd party VMMs like Oracle Virtual Box or VMWare will probably not install and inform you that virtualization is not available (!). Use Control Panel Apps and features to disable the Hyper-V App.

While unboxing your new external USB 3 storage device you see that the device uses a USB Type-C connector on both ends. What is the highest connection speed you can expect when correctly connected to your new computer?
12Mbps
480Mbps
5Gbps
10 GPS
Explanation: USB Type-C runs at a maximum speed 5Gbps. In a perfect world you can reach 5 Mbps over a USB 3 to USB 3 connection Your actual speed will be determined slowest link in the chain and connection overhead. Here it would be the highest speed supported by the host. The USB speeds are, USB 1 at 12Mbps, USB 2 at 480Mbps, USB 3 at 5Gbps, and USB 3.1 at 10GPS.

Correct answer: 5Gbps
A customer calls stating that he has a Web-enabled printer installed on his laptop. He uses it to print copies of invoices. When he is in his home office Web printing works without any issues. While working on his remote service calls he prints the invoice for each call back to the office. When he gets back to his office nothing is printed and the queue is empty. The properties report the IPv6 address as fe80::e6e7:49ff:feb8:db04%12. What is the problem?
Web printing uses IPv4
The printer is out of paper
The IP address is not valid for web services
The firewall is blocking print services
Explanation: When you check the IPv6 address you see the first segment is fe80: This indicates a link-local address. Link-local Pv6 addresses are assigned using APIPA to allow local LAN communication. These addresses are not forwarded by routers. This explains his ability to print locally but not outside his home network.
Main Domain: 3.0 Hardware
Sub-objective: 3.6 Given a scenario, deploy and configure multifunction devices/printers and settings.
Correct answer: The IP address is not valid for web services
You have a new PCIe video card to install on a PC. What slot form factor will the device typically require?
NGFF
M.2
PCI Express
mSATA
Explanation: A PCIe card will use A PCI express slot on the PC. For space-saving designs like laptops or “All-in-one” PCs the M.2 slot is the latest version and supports very small devices like SSDs. This connection type began as NGFF (Next Generation Form Factor). mSATA is a storage solution.

Sub-objective: 3.4 Given a scenario, install and configure motherboards, central processing units (CPUs), and add-on cards.
Correct answer: PCI Express
Microsoft Windows includes a virtualization feature that launches a VM that can be used for testing. This feature is limited to one active instance per system. What is it called?
Secret Garden
Sandbox
MSVMD
OneDrive
Explanation: When enabled the Windows OS Sandbox feature lets you launch a virtual machine that is isolated from the host system. It is fully functional. The catch is that, unlike true VMs, you cannot save the Sandbox and any changes are permanently lost when it is closed. A Secret Garden is a web portal used by shared network connections in hotels and coffee shops. OneDrive is a Microsoft cloud-based storage solution and MSVMD does not apply.
Main Domain: 4.0 Virtualization and Cloud Computing
Sub-objective: 4.2 Summarize aspects of client-side virtualization.
Correct answer: Sandbox
A user reports that his PC makes a grinding sound when he opens Word documents on his storage drive. The user is currently using a 1TB HDD for storage. You will be going to the site and instructing the user to shut down the machine. What specific item would you bring with you?
Cleaning equipment
A 1TB HDD
Disk diagnostic software
A 1TB M.2 SSD
Explanation: You will want to bring a replacement 1TB HDD to replace the hard disk. The disk heads are contacting the disk. Data destruction is a very possible outcome of continuing to use the drive. Immediate shutdown will prevent further damage. An M.2 SSD is an unlikely fit. Your service kit should contain diagnostic software and cleaning supplies.
Main Domain: 5.0 Hardware and Network Troubleshooting
Sub-objective: 5.3 Given a scenario, troubleshoot and diagnose problems with storage drives and RAID arrays.
Correct answer: A 1TB HDD
You are adding an additional SATA disk to a PC and the only available motherboard connector is labeled eSATA. Can you connect the SATA cable directly and drive to it?
No, you need an adapter
Yes, but it will be slower
Yes, the SATA cable will connect properly to the eSATA port
No, the performance impact is too great
Explanation: The SATA cable will fit perfectly and may even provide better performance. Naturally, the new disk will need power and you may need to check BIOS/UEFI to be sure eSATA is enabled.
Objective: 3.0 Hardware
Sub-objective: Explain basic cable types and their connectors, features, and purposes.
Correct answer: Yes, the SATA cable will connect properly to the eSATA port.
You need to run a twisted pair of Ethernet cable. The cable should use RJ-45 connectors and support speeds up to 10 Gbps over a distance of 95 meters. Which would be your best choice?
Cat 5
Cat 5e
Cat 6
Cat 6a
Explanation: Cat 6a is the best choice because it supports 10Gbs for 100 meters. Cat 6 also supports 10Gbps, but only on runs of 55 meters or less making it unsuitable in this case. Cat 5 and Cat5e do not support your requirements.
Main Domain: 3.0 Hardware
Sub-objective: 3.1 Explain basic cable types and their connectors, features, and purposes.
Correct answer: Cat 6a
Of the choices provided, which does NOT support small form factor digital storage?
NVMe
mSATA
SATA
M.2
Explanation: SATA supports 2.5” and 3.5” drives These are not considered small form factors. Significantly smaller drives can use NVMe, mSATA, and M.2 are all small form factors.
Main Domain: 3.0 Hardware
Sub-objective: 3.3 Given a scenario, select and install storage devices.
Correct answer: SATA
