The preferred wireless network is a list of wireless networks that you have already connected to in the past. This is a prioritization of the wireless networks you choose to take precedence. This is not related to DHCP. APIPA is a zero-config technology as you have already mentioned and are correct!

No, they are not the same, wireless repeaters are devices increase or boost the Wi-Fi signal in areas that the antennas cannot cover well and that extend the range of a WLAN. A long range fixed wireless is essentially a Wi-Fi bridge that can for example connect to building's Wi-Fi networks together that is owned by the same organization.

Yes...that does happen but you can check my work! ;)

The answer is yes, Android devices will use GPS for location, Wi-Fi and cellular communications for geo-location as well.

Hey @Mian-Talha-Zia I am not sure of the question, but I will answer with what I believe is the context. Wireless environments and Ethernet for wired networks will use the zero-config technologies such as APIPA addressing, IPv6 addressing components such as EUI-64, communication protocols such as the Simple Service Discovery Protocol or SSDP and Multicast DNS which require no human interaction or manual configuration.

The answer is no.

@Mian-Talha-Zia, great question, and like another question you asked, context it key! Most touch screens use a built in digitizer that transforms analog signals into digital signals to be processed by the system. Second, this depends on the display type, for example if it is capacitive touch, these screens use the electrical properties of a human finger. If it is resistive touch then almost any object will interact with the screen (stylus, finger, pen). In the case of a touch pen that uses a light sensor then this type of pen can have a small lens that tracks motion from the pen and send the signal to the computer (for example Samsung Galaxy S Pens). In the case of a Wacom tablet touchscreen, these have pens using EMR or Electro-Magnetic Resonance.

Hey @Mian-Talha-Zia, the confusion is in the acronym. You have two acronyms that are different topics, one to do with ISDN offerings for network connections called Primary Rate Interface or PRI. The next one is PRL, this is Preferred Roaming List or PRL, which has to do with cellular communications. The Preferred Roaming List is a database used by cellular devices (mostly CDMA-based platforms) and carriers to determine system selection when roaming outside of the main carrier's network and connecting to other "towers". With this context, the answer to "what update would update the PRL" and the answer should be OTA Firmware updates. These are over-the-air updates downloaded through the carrier's network to update the radios (such as baseband, Bluetooth, OS, PRL and more).

Hey @Mian-Talha-Zia, you have to understand the context of the question and what is being asked. You should pay attention to key words that modify the conditional or circumstances of the question such as "which is the BEST," "which is NOT," or "LEAST likely." If you fail to review any references, you will increase the likelihood getting the question incorrect.

This is how your device receives data. It can be "pushed" to your device. Or your device can "pull" or request data from the server. If your device is pulling data it doesn't necessarily have to update; if the data is being pushed. The data is sent regardless of whether you want it or not.

Yes. Usually, wi-fi hotspots are standalone devices and not merely settings on phones. Technically, tethering is when you connect, physically a device to your hotspot "tethering" it to the hotspot. What you are doing is turning your that hot-spot into a Wi-Fi hub and allowing those devices connecting to that wireless hub to share the cellular connection.

One thing that I would like to add to this thread @Dwayne-Coleman, that I forgot to mention is there are reserved addresses as well. For example, 127.0.0.1 (loopback processing), 169.254.x.y. (APIPA addressing) and 255.255.255.255 (sending communications to all hosts on a network), that are used for special circumstances.

@Brian-Wafula AWESOME!! Congrats Brian! I'm glad my advice was able to help you pass your exam.

Good luck with the Linux+!

@Mian-Talha-Zia,
If we do not have any lab attached to the course. Then the labs do not exist. This makes sense since we are providing virtual labs and 220-1101 is mainly regarding diverse hardware connections and hardware devices. These are not possible to virtualize. It may be one that that we can provide a simulation of that but we do not currently have those for our 220-1101 course.

@John-Long,
The number to watch is not on the result (MT/s) but on what makes it happen is that prefetch number. This is the number that continues to double between the generations that you mentioned. That number is about how much data can be accessible at any one point in time. This time that number is about bits, and bits doubling allowing more binary data in in each generation. the 2n is 2^2 = 4 bits = 4 , etc. by the DDR5 it's 2^16 = 16 bits = 65, 535. Each successive generation has been able to process more data at the faster speeds you've mentioned. An analogy: how many people you can carry, on a speed-bike you can carry 1 or 2 people really fast, but it's still 1 or 2 people. But if I drive a school bus that has more seats but also is faster than the speed bike...how many more people get to the destination faster? Those bits then are about capacity at a given speed.

This is the tricky part. If you have a mobo that you can mix and match ram, which most don't but if you do...it will only go as fast as the slowest speed ram you have...which means you can make faster RAM go slower; but you cannot make slower RAM faster.

@Jeff-Braasch sure thing! If you have any questions during your training, do not hesitate to ask!

I highly recommend the use of the Exam Cram books. They were great when I studied my A+ back in the day and their Net+ book is also very good.

The All-In-One books by Mcgraw-Hill are also very good.

If you can, getting hands-on training beyond the virtual labs of ITPro helps with understanding concepts as well. Setup some Hyper-V or VirtualBox devices and get them talking/set up services for them.

It is not according to the published exam objectives from CompTIA. More than likely, the benefits and adoption of RAID 10 outpaced RAID 6.

Robert,
Yes, RAID 0 - 5, meaning 0, 1, 3, and 5, it gives you the ability to recover the from the failure of 1 drive. If 2 or more were to occur this would not be recoverable. e.g., RAID 5 with 3 disk...could recover from failure of 1 drive.....but even with RAID 5 with 31 disks. It would also only be recoverable if 1 disk were to fail. 2 disk failure here would be unrecoverable.
