• can I see my exam questions?

  Hello world

  I want to study my mistakes of my exam 1Z0-899, that I took yesterday.  I see the summary of the sections where I was wrong, but better to concentrate my studies - is it possible for me to see the real exam questions to see what questions I answered wrong so I can understand these issues to the categories in my summary of the review?

  It's just my college experience, I always had the chance to see my exam questions.  Even for the final exams of the instructors at the University has generally make an appointment with students so that they can see their final exam questions and the mistakes they did.  It's just that I was in universities for too long and can't help but think this way.  So could I see my questions in the examination again please?

  Thank you kindly,

  Victor.

  You cannot resume a review for 14 days.  However, there is no limit to the number of attempts at recovery.

• Difficulty of VCP4 exam question

  Hi all

  I'm studying for my VCP4 exam next week and had just a small question about the quality or the difficulty of the questions on the real exam. Basically, I was wondering if the simulated test questions and SLOG are representative of the actual exam questions? I used two of these resources and have received good results, but I don't want a rude shock when I get to the real deal!

  See you soon

  Welcome to the community.

  Some questions are at the same level difficult, others too easy...

• fast sampling rate question...

  Hello

  I use USB-6009 and max sampling rate is about 48 K samples/s according to

  the specification...

  Question 1.

  48 K samples/s means... only when you receive 1 analog input?

  If I have 2 analog inputs then forge would be just half of the 48K?

  Question 2.

  using the daq assistant.

  I would like to get about 50 samples between 10ms

  If I do the math I get 5 K samples/s, which is enough for me

  However, I played with samples to read and throughout the day, the sampling rate,

  do not get this rate... (I'm outputing in file with LVM)

  I searched on the sampling frequency, and people here said

  samples read and sample rate do not havea correlation...

  but I see clearly that they are relevant. When I change a setting

  I get a different number of acquisition... I do N smaples.

  Please help:)

  Q1. Yes, except that the switching of channels takes awhile so the net price per channel is slightly less than half the rate of single channel.  The USB-6009 specification document does not indicate what is the switching time.  You should be able to get 5 kHz on both channels.  20 kHz might be close to the upper limit, but that's just a guess.

  Q2. The DAQ Assistant is often not the best choice for maximum performance.  I do not have the DAQ Assistant, so I can't be more specific. If you get the data as an array of DBL, rather than dynamic data type, it can be recorded directly, without conversion.  The other thing that can make a big difference is a loop two architecture of producer/consumer.  This allows the acquisition of data and save it to the file to run it at different speeds so that each can be optimized separately.  If you are trying to acquire 50 ms of data at a time and then, he writes to the file, you write to the file twenty times per second.  The first time, the operating system must reallocate some file space or do something else what delays write the file, your timing loop is disrupted.

• compactDAQ sample rate question...

  OK, I think I have a question in the right place, but if not I have forgiveness.  :-)

  I have a CompactDAQ (4slot) with just a 9225 and 9239 modules installed.  I've run the DAQ assistant and have all seven current channels of reading and writing in a text file of a structure of event... when I push the button, it saves the data.  Quite simple really, I have also a timer Setup 'Wait' with a 50mS wait time, so I'm basically updateing my loop 20 times per second, not so fast.  The strange thing is that my DAQ module is only send me data once per second.  A I put something wrong?  Seems to me that as updates of loop, it should return 'true' the key to the structure of the event and the data should appear at a rate of about 20 samples per second.   VI attached sample.

  Tips and points in the right direction are greatly appreciated!

  Chad

  Hi chuggins143,

  The behavior comes from your settings in the DAQ Assistant:

  

  If you want the loop to run 20 x per second, then 'Samples to Read' should be 1/20 of the sampling frequency.  DAQmx hangs until the samples 'Samples to Read' became available, so it's slowing down your loop.  You can also change the Timing settings to 'Continue', if you want to avoid gaps in your data.

  Best regards

• On the NI PCI-6221 fast sampling rate question

  Hi I was wondering if someone can answer a question of sampling rate on this card to PCI-6221 (http://sine.ni.com/nips/cds/view/p/lang/en/nid/14132).

  Especially if I wanted to transmit simultaneously (analog output) and data acquisition (analog input), what is the sample rate max I could use. Kind regards.

  Since the 6221 is multiplexing the analog input, your question for I / simultaneous ao is possible for one channel of the only. If your "simlutaneously" can include delays (e.g., 100us), you may be able to work with several AI channels as well...

  HAVE the multiplexes, workable sample rate given that the total sample (250 kHz) frequency divided by the number of channels that you use. AO is faster than HAVE it, so it does not reduce this number.

  hope this helps,

• Practical SQL training/exam question

  Hello

  I am a student at the bases SQL 1z0-051 exam, and examples of questions about the Oracle University site review is the following:

  3. review the structure of the EMP table:

  EMP                                      

  Name                                  Null?                        Type

  ------------------------------------------------------------------------------------------

  EMPNO NOT NULL NUMBER (3)

  ENAME                                                               VARCHAR2(25)

  SALARY                                                              NUMBER(10,2)

  COMM_PCT                                                        NUMBER(4,2)

  You want to generate a report which meets the following requirements:

  1 shows the names of employees and the commission amounts

  2 excludes employees who do not have a commission

  3 displays a zero for the employees whose SALARY has no value

  You run the following SQL statement:

  SQL > SELECT ename, NVL (salary * comm_pct, 0)

  WCP

  WHERE comm_pct <>NULL;

  
  

  What is the result?

  It generates an error

  B it runs successfully but displays no results

  C it runs successfully but displays results that meet only the requirements 1 and 3

  D it is running successfully and displays results which fulfil all the requirements

  The answer provided on the Web site is: B it runs successfully but displays no results

  and I don't understand why...

  
  

  The WHERE clause excludes rows with comm_pct is NULL. So for the function NVL in the SELECT clause, the value of comm_pct will never be NULL, but salary * can * be NULL (there is no NULL constraint on this topic), so for lines where the salary is NULL, salary * comm_pct evaluate to NULL and the function NVL would transform these nulls to 0.

  
  

  Am I missing something?  I realize that for some people on this forum, the answer may be obvious, but I'm learning just for the first level of certification SQL, so for now I still have a lot to discover.

  
  

  Thanks in advance,

  JM
  

  x <> NULL

  x = NULL

  Neither is never true. NULL is never equal to what whatsoever (including NULL). NULL is also never not equal to what

  X IS NOT NULL

  X IS NULL

  are the right way

• VCAP5-DCA exam questions

  You are able to read each question carefully to review before you start your first task? I don't know whether to click through 26 screens to see each question or figure it out in the begin block? Thank you

  Ed

  Yes, you can click around the review, as you can do on most VMware exams.

  There is a school of thought that clicking through all the questions and take notes you if an item is a 'create' or 'admin', their organization and then clicking back to the beginning will save time to review.

  There are a few problems with this:

  -This excersise will take you 10-20 min.  Since you have an average of 8 minutes per question, you give ~ two questions when you try this method.

  -try to determine how long will take an item or if the item is a 'creation' or 'admin' question before trying the question in fact is not always possible.  Many questions have troubleshooting components that aren't obvious until you try them.  Some read as a matter of "admin" but actually need to create components on the fly.  Some of the lists "create xxx" but that's actually a later configuration element and the question really is a "question of the admin".

  -l' review is designed to take one at a time, in order.  Items that can cause disruptions tend to go towards the end of the examination, the elements that improve the performance of review go near the front.  The items that can interfere with other elements are carefully.  A passage which does no favor.

  Note that these points are all exams live-lab, not only VCAP5-DCA, and some points are more important in some reviews.

• OCP current Database 11 g exams Question (specifically 1Z0-053)

  Hello

  Are the current reviews of 11g certification strictly based on 11 GR 1 material or 11 GR 2?

  While the studies and have questions, I don't know if I should look into 11 2 GR or GR 11, 2 official documentation to find answers.

  Maybe there are some differences between these two versions that can guide me badly on the possible test questions.

  Thank you

  Bruno

  The reviews were created against 11 GR 1 material, but have been validated against 11 GR 2.  OU is not * need * questions in exams that have a different response between versions.  11 GR 2 validation would ensure that none exists.  I recommend you to study the documentation of R2, because it is always better to make use of the most recent incarnation of any given major version.

• Some VCAP-DCA exam questions

  I take this test on Friday and have a few more questions I couldn't find answers for it:

  Several takers review mentioned that there is only the vma and ESX servers. What about PowerCLI? Is there any explicit questions or tasks MUST be completed with PowerCLI? If it is not installed, it is no use learning, isn't it? (except the actual skills very useful)
  Are there tasks MUST be accomplished using VMA/CLI/vSphere client/PowerCLI or this is my choice, what tool I take to accomplish the task?
  One more: I've read that vscsiStats is not installed on the ESX Server. Do we need to install it during the exam or if all the tools are pre-installed?
  I guess that these questions are not subject of the disclosure to sign...
  Thanks to adnavce for your help!

  5- DCA VCAP, you're right that AutoDeploy is included under the headings of the blueprint, of Update Manager PowerCLI is also mentioned.

  But for VCAP,4- DCA, I would describe the required level of knowledge as pretty basic PowerCLI.

• Exam question-value of the point and unanswered questions about the VCP4 exam?

  Hello

  I have a few questions about the scoring to secure Channel 4 review system:

  1. All the questions on the exam are weighted the same?

  2. Is there a penalty for unanswered questions?  In other words, is it better to not answer a question, if you are sure that you do not know the answer, or take a guess if it comes down to it?

  Thank you very much

  Bryan

  Not responding not to an element, it is the same thing that answer wrongly as far as scoring is concerned, so it makes sense to guess rather than leave the question unanswered.

  With respect to the weighting, all elements have the same weight in the VCP exam, but some items do not count against the overall score.  These "dosed" items continually change and are chosen at random.  We insert elements assayed to determine the validity of the element until it became a party has received from the real exam.  If however, you want to treat each item with an equal amount of importance.

  Hope this helps,

• Can I expect to consult vSphere 1 update of the VCP - 410 exam questions

  I have my VCP-410 exam tomorrow and am wondering about the question to know if I am likely to see changes in the review of the recent release of vSphere update 1.

  An example may be the fact that the PVSCSI is now supported by the boot floppies (windows 2003 / 2008) where as before it was not.

  I'll assume that 1 week after the release of these changes are likely to appear.  For future reference can someone VMware tell us how long after an update can we expect the review to take account of any change in software?

  Hi all

  We always try to maintain compatibility with the current versions of the product.  Which means that you can study the current documentation.  As Scott mentioned, we probably will not add new items immediately, but us correct inconsistencies with existing items.

  Kind regards
