Microsoft Finds a Third Print Spooler Bug

March 19, 2021 in Certifications, IT News by

Microsoft finds another bug in Windows print spooler

Microsoft is again urging its customers to disable Windows print spooler, warning of a new escalation-of-privilege vulnerability in all Windows versions, even those with the recent PrintNightmare patch. This is the third print spooler vulnerability to emerge in five weeks.

Another zero day vulnerability in Windows Print Spooler can give a threat actor administrative privileges on a Windows machine through a remote server under the attacker’s control and the ‘Queue-Specific Files’ feature.

Last month, a security researcher accidentally revealed a zero-day Windows print spooler vulnerability known as PrintNightmare that Microsoft tracks as CVE-2021-34527.

Exploiting this vulnerability lets a threat actor increase privileges on a machine or execute code remotely.

Don’t Be Scared to Test at Home This Halloween!

Does the thought of taking your test at home send shivers up your spineAre you scared that you will fail because you won’t be ready? Does the idea of having someone watch you make you feel like you’re in a bad 1980s video sung by Rockwell and Michael Jackson?  

It’s OK to get a little nervous before plunging into the unfamiliar. This may be not only your first time taking a CompTIA exam, but also your first time testing from home! Luckily, you’re not alone in having those feelings as this is a new process for most of us. 

 

Not a proctor, just the world’s creepiest shoulder surfer.

I Ain’t Afraid of No Ghosts

We’ll help you overcome your fears by helping you prepare. Fortunately, many others before you have already done it successfully. After all, CompTIA allowed testing from home on April 15. Other vendors like Certiport and Cisco, among others, have done the same. 

By the way, if you want to check out those other certifications or get some more last-minute practice, then check out our materials here:

Test at Your Favorite Haunt

With a strong Internet connection, a computer that meets the requirements, the right ID materials, and no prohibited materials or distractions in the room, then you can test safely from home. Also, make sure that you plugged your computer into a reliable power source and aren’t relying on the battery.

Good news! You don’t even have to test at homeyou can test from work, or also a public library! You cantake the test from a tablet or mobile phone at this time.

What happens when you keep putting off scheduling the test.


Bad Things Come in Threes … Unless You Prepare!

First, you should check if your computer would work under exam conditions. Take the official system test to see how well it would perform on the day of the test: 

https://service.proctorcam.com/system_tests/launch_test?app_locale=en_US&session_id=6866079&template_name=onvue_system_test#top 

Assuming that you pass, then your next biggest concern will involve having a high bandwidth because you will use streaming video and audio for the entire two hour testYou should try a speed test. 

Ideally a wired connection works best. If you have only a wireless connection, then ensure that others in your area turned off their connections temporarily. Better yet, have them leave during test time. Yes, Big Brother is watching you, so give him a gift card for a coffee, send him trick or treating somewhere, or give him a book to read.  

Now that you know you have the proper equipment, you need to get familiar with the test format. Unfortunately, because you cannot use notes on paper or electronic devices to remember things, draw diagrams, summon spells, or perform calculations, you’ll use a sheet on the screen for your notes. Wreally, REALLY recommend that you practice using this feature before so that you don’t waste precious time learning how it works during the test itself:


https://home.pearsonvue.com/onvue/whiteboard 

My proctor quit after I tested for some reason.

Now, if you do these three thingsyou’re pretty much ready to test at home by this point. But you should also know what to do for the test itself. 

Don’t Ghost Your Test at Home! 

Just as with any standard test center, you should arrive 30 minutes early. The check in process takes 15 minutes. If you’re scheduled at 1 PM, then get online and be ready by 12:30 PM.

Screams and tears won’t make you any less late. Arrive early to avoid upsets! No exceptions!

The proctor will explain the dos and don’ts. You will provide an ID copy, just like at a testing center, but good idea to bring two in case one doesn’t count.  

The proctor will validate your ID with the Web camera and explain the rules. This means that you will need to make sure that your camera, microphone, and speakers work.


Just Because You’re Paranoid Doesn’t Mean They’re Not Watching You

The camera must be positioned so that the proctor can see you, the screen, and keyboard. Software will record your test screen even if you somehow block the Web camera with your hand, so you can’t “accidentally” block the screen. Trust us, we thought about it and they beat us to it already.

You cannot wear any phones, headphones, headsets, electronic devices, pagers (if you’re in a 1980s costume I guess), watches, wallets, purses, hats, head coverings, bags, coats, books, notepads, pocket protectors, or anything else not approved. Clothes are optional but we highly recommend them.

Wait, so we’re supposed to be afraid of her for not wearing a mask? Clown world indeed. Go, 2020!


I Can See Your House From Here…  

The proctor will also make you pick up the Web camera and do a 360 view of the entire room. Therefore, you must remove all electronic devices, audio devices, notes, cards, books, scrawls on the wall/ceiling, floor, and any people who could possibly give hints, tips or cheats.

You can’t have notes, books, papers, pens, pencilsmonitors or computers (or at least they must be turned off and unplugged), whiteboards, blackboards, Ouija boards, bloody messages scrawled on the wall, etc.

Are you moving it or did the mouse run out of battery and stop syncing again?

You won’t pass if you fail this preview of the roomThe camera also will help the proctor to see if you’re checking your pockets, looking at the floor, or glancing around during the test looking at things that can help you during the test. Basically, you must look at the screen only.

Sure it’s disturbing, but at least they can’t accuse you of cheating on the test!


Don’t Rely on Phantom Power

You will also need to enable your microphone. That system test that you did earlier should check the microphone component. CompTIA doesn’t want someone to record the questions with hidden microphone, therefore you cannot talk to yourself during the test. Besides, it’s kind of weird. Psychic communication with spirits is technically not prohibited, but since they’d probably only know old versions of the test anyway any ghosts in the machine won’t help you very much. 

We prefer the term living impaired, thank you.

CompTIA Will Soon Mean for Computer TestIng At Home (The H is Silent)

That’s pretty much it! You can now take the test and with our help you’ll know all the content so that you can pass the exams with ease. Once you’re done, the test will ask demographic and basic questions – just like they do at the test site examinations – and THEN it will give you your results. You will get a hard copy in the mail and you can get a digital copy on the spot.

We hope that you have a safe and Happy Halloween and that you succeed on your exams! Now go study, register, and test, then let us know how it goes! 

Uh, you go first. I’ll be right behind you.

CompTIA online testing coming April 15th

April 3, 2020 in Certifications by

CompTIA Online testing coming April 15th

CompTIA uses Pearson / VUE testing centers to administrate their Certification Exams. Due to the Covid-19 pandemic many of the VUE testing centers have closed around the world. In response to this, CompTIA is working with VUE to launch their online testing program.

CompTIA has been working on creating an online testing alternative for over a year and hoped to launch it by the end of 2020. Due to the Covid-19 issues they have accelerated the launch of their online testing program and CompTIA will be launching online testing April 15th.

CompTIA is partnering with VUE to use VUE’s new OnVUE platform to administer the online exams. You can learn more about OnVUE HERE.

Here are some details from CompTIA:

  • Online Testing: StartingApril 15, 2020CompTIA will be offering online testing, with remote proctoring, that will allow candidates to take their CompTIA exam at home, anytime, while maintaining a secure testing environment.

Note: Please be aware there is high demand for online testing with remote proctoring. Candidates will be able “schedule” their exam starting April 15th; however this does not mean that candidates will all be able test on that date.


  • Online testing will NOT be available: Cuba, Iran, North Korea, Sudan, Syria, Japan, Slovenia, China and South Korea. Pearson OnVUE platform is not available in these select locations.

  • Exams Available:All exams are available, with a few exceptions. Server+ won’t be available until May 1st, 2020. Not Available: CTT+ and any site licenses.

  • Languages:Remote tests are available in all languages for which the exam is currently offered, however the proctors are English speaking only. The Pearson OnVUE platform is also English only.

  • Rescheduling Exams: Candidates may reschedule an exam at a Pearson VUE testing center at any time. If candidates would instead like to take an online exam, please reschedule your exam on or after April 15, 2020.

We will update this blog as additional information becomes available next week.

Testing Strategies for CompTIA Exams

September 15, 2019 in Uncategorized by

CompTIA includes performance-based questions on their exams to make them more practical and keep up with trends in certification testing. Knowing what to expect and how to approach these question types is key to your success in passing the exams. First, let me fill you in on some facts about the exams.

Exam facts:

There are several different types of questions that may be included in your CompTIA exam:

  • Multiple choice – the standard question, pick the right answer
  • Multiple response – question, pick all that apply with more than one correct answer
  • Fill in the blank – question, fill in the answer to the question
  • Drag and drop – image or question where you drag answers to match the image or text
  • Exhibits – answer questions relating to an attached picture or diagram (variation to Multiple choice)
  • Performance-based – detailed question, open dialog boxes or other configuration windows and configure as needed.

CompTIA is adding more of the newer Drag and drop and Performance-based questions to their exam pool. You may get as few as 2-3 or as many as 10-12 of these newer type questions depending on which exam you are taking. The more of these new type questions you get the fewer of the traditional multiple choice, multiple response or exhibit type questions you will have, depending on the difficulty of the performance-based questions you get.

How new question types are graded:

Two important pieces of information about the new drag and drop and performance-based questions that you need to know:

  1. Partial Credit; Scoring credit may be offered if a candidate answers only part of a question correctly.
  2. No Negative Credit; CompTIA does not employ negative scoring on exam questions. In other words, scoring credit is not taken away for incorrect answers. A candidate should answer every exam question, even on the ones where they are not sure of the answer.

Testing Strategies:

The new question types like drag and drop and performance-based questions will be presented at the beginning of the exams. These questions can be more complex and take longer to answer than traditional multiple choice questions. DON’T GET BOGGED DOWN WITH THE PERFORMANCE-BASED QUESTIONS. You can skip questions and come back and answer them at the end. Here are some strategies to use when taking the exams:

  1. Skip the Performance-based questions and come back at the end to answer them so you don’t get bogged down and run out of time.
  2. Count the performance-based questions as you skip them so you know how many you have to do when you come back to them at the end.
  3. Read over all the performance-based questions and answer the ones you are most comfortable with first. Leave the ones you are less confident about until last.
  4. If you are not sure about some of the steps in the performance-based or drag and drop questions, give it your best guess. You may receive partial credit. Since CompTIA does not employ negative scoring a wrong answer does not hurt you any more than an unanswered question. Make your best guess, it can’t hurt you.

CompTIA provides information that may be helpful in preparing for the exams at the following links:

CPU-Z: Info on Your Core Components

August 23, 2019 in Mike's Cool Tools by

There’s few tools more useful than Frank Delattre’s amazing CPU-Z, available over at www.cpuid.com, to help learners wrap their heads around processors speeds, multipliers, CPU family/code names, cache, RAM timings, and SPD (RAM serial presence detect) than this wonderful product. CPU-Z has been around for almost 20 years but it’s very well supported and constantly updated.

The fun starts the second you run the tool, opening you to a host of nerdy details about the CPU.

Isn’t that a wonderfully simple way to show a CPU multiplier? Even better, it shows the motherboard speed which you can use later to multiply DDRX memory.

Ah, the cache sizes. Yeah, I know: no one really needs to know cache but it definitely fits under Mike’s CiC (Cuz’ It’s Cool) rule. Honestly, there’s enough cache information on the CPU tab I rarely use the dedicated Caches tab.



Total Seminars has resources to help you study for your CompTIA Certifications

Practice Tests: TotalTester has hundreds of questions in a pool that allows you to create custom exams by exam domain or by chapter. Take exams in Practice mode with assistance (hints and explanations) or in Final mode to see if you are ready for the real exams. Complete explanations for each question.

Discount Exam Vouchers: Purchase a CompTIA voucher and save on the cost of your exams.



My next favorite tab is Mainboard. Manufacturer, model, Southbridge, and IO chip are great, but it even tosses in the brand, version, and date of your BIOS – need to flash? Find out here.

The Memory and SPD tabs give almost the same information: RAM type, speed (shown in both PCX-rating and DDRX), even part numbers. These are great but I prefer the way the SPD tab shows the used and unused RAM slots on my motherboard – sure beats crawling under a system to see how you can add more RAM. Also, if you’re brave enough to show RAM timings (handy for learning overclocking) this tab is very clear and easy to read.

Last is the Graphics tab. It really only answers one question for me but it’s a big one: “What graphics card is in this computer?”

Look, I admit it. I’m a CPU-Z fanboy. It’s free, fast, safe, and provides accurate detailed information. This tool is on my thumb drive and in the hands of every entry-level standalone student I teach. Thanks, Frank!

Wireshark As a Tool to Introductory Networking

August 2, 2019 in Uncategorized by

Wireshark As a Tool to Introductory Networking

I’ve been using Wireshark, or it’s precursor Ethereal, since the late 90s. For those of you who don’t know this amazing tool, Wireshark is a free, well-known, powerful, open source protocol analyzer. Wireshark, along with its built-in capture tools, gives network support people an amazing set of tools to see almost anything you need on the packet/frame level of your networks.

Wireshark is truly one of those “mere moments to understand, a lifetime to truly conquer” type of tools because of the sheer amount of information it provides. You use a capture tool (Wireshark includes two different ones) to grab a bunch of packets, then see those captured frames in the primary interface. This three-part interface is simple: The top part contains your captured frames, each row represents an individual frame. The middle has expandable details of whatever frame you’ve selected from the top area. The bottom third displays the same selected frame in raw (hexadecimal) format.

Using all the features of Wireshark is wildly complex and powerful but I love to use this basic interface as a tool to expose brand-new networking students – and I mean DAY ONE learners – to several fundamental networking concepts. Let’s see what Wireshark does for me instructionally.

Note: I’m not saying that I sit down with students on day 1 in front of a Wireshark screen without anything else. I’m a huge believer in giving students motivation via lecture, toy blocks (just like the ones I use in videos), hats, and plenty of jokes to bind individual concepts. Wireshark comes in after plenty of concept instruction.

OSI

I like teaching the OSI model as it gives learners an organization to separate network features, especially layers 1, 2, and 3. Wireshark makes this downright fun by pre-organizing each of these layers in the second field. Note in the following figure how layer 2 MAC addresses and Layer 3 IP addresses show up so clearly. The top line, “Frame 4498” is Wireshark’s method for keeping all the frames in order.

If you’re a brave instructor, go ahead and show the port numbers as well. I love to use the line “IP gets you to the right computer, but ports get you to the right application.” This is also a SCREAMING opportunity to pull out those toy blocks and start talking about Protocol Data Units (PDUs). I’ll go ahead and start defining Ethernet frames, IP packets, TCP datagrams, etc. – and why not? They are literally LOOKING AT PDUs as you speak so why not define them?

Did I mention this is DAY ONE instruction? Heck, this is the morning of Day One!

Packetized Data

At this point, you’ve got the learners eating out of your hands with PDUs. Let’s go ahead and make sure they understand the idea of packetized data and the need for a stream of packets to send one piece of data. My favorite lab is to have them run a capture of a HTTP page (not HTTPS!) and run the “Follow TCP stream” feature to see the raw output. Then close the stream and show them the filter Wireshark adds to filter out all the other frames.

Encrypted/Unencrypted Data

I spend hours of course time on encryption but now that you just showed them unencrypted data why not just grab a quick HTTPS page and make a helluva teaser for those later lessons? Don’t linger on this as it’s just a teaser.

Switch Functions

I know. I’m old. I still lecture on hub vs. bridge vs. switch. Learners often have a problem with the idea of switches without a demonstration. Just plug into a switch and run Wireshark. Let the student look at the destination and source IP addresses – it’s only unicast and broadcast (you might want to avoid multicast this early but I’m still on the fence about that).

This might even be chance to add a column for destination MAC address and a filter for MAC address = FF.FF.FF.FF.FF.FF. These are easy to do in Wireshark.

Protocols

OK, I don’t do this on day one, but with a good intro to Wireshark early in the course I can turn back to it over and over. I love to show protocols at work using Wireshark. One of my favorites is DHCP. Here’s a screen of a four-step DHCP process. Quiz: Why does DHCP take four steps? Couldn’t it work in just two or maybe three? I’ll answer this in a few days.

These are just some ideas that you’ll want to consider next time you’re teaching an introductory networking course. I think Wireshark is an amazing tool with a simple, intuitive interface that wonderfully reinforces so many fundamental networking concepts. Give it a try!
