Why this link ------->We can also  just straightly goes to gatebook test series question in link and post it but then other persons will not be notify about your doubts …… and then  your doubt will be there for a long time maybe as ( RECENT  ACTIVITY  ) option changes very fast, so may be no other person or any VETERAN level users didnt get notify about  your doubt and then there is very much probability that your doubt will be removed when you are doing another subject …….. thats why i am creating this blog .

GATEBOOK-2019-OS2-11  can anyone help with diagram or some theory in this question

https://gateoverflow.in/271098/gatebook-2019-dbms2-3

In this question the given answer is $(A)$ but the right answer is $(C)$

In this take any set value there is always a possibility of deadlock. Hence B is the answer.

@Deepanshu

i was thinking of posting a similar one regarding the answers of Gatebook.

Today while solving some on DS, I found many answers not matching with mine. I would request @Arjun sir to recheck and confirm the answers on DS for once if he gets time.

hmm questions are of superb quality ....... but sometimes  solutions are wrong and moreover noone  is commenting on them except who  just gave that test and seeing solutions and as every test is not enrolled to everyone so there are very less comments on them ...... but this blog has its own disadvantage like we cant see questions of tests  which  we dont attempt... :(

Gatebook should provide solutions and also the more people solve the faster we can discuss, i attempted Graph Theory test and have many doubts but no one has attempted it so i can't discuss.

@Mk Utkarsh

if you have doubt on any question... you just comment there... then after writing the exam someone will understand your argue on that question...

yes doing the same

formatting is not good and i think answers of few of the questions are not correct

just type your comments there, if i complete my exam, then i will see

Please elucidate this really important issue.

@rahuljai

don't post which are non-GB questions under this Blog... if you do that, then everyone will copy their questions here...

Moreover add relevant tags for that question ( you tagged stack and data-structures for that question which are not related to the original question )

Finally, the answer given by Bikaram sir is correct !

Please, explain the logic behind this. Can't get my head around it.

What significance does this line holds in this question?

If there is a common routine of size 50KB which must always be in memory then the
amount of memory required to load and run this program MM in memory (in KB) is:

I think the translation looks like Tag=29 Set=7 Offset=14. Then, adding process id to tag bits. = 42 bits. and hence total TAG size = 42Kbits. Where am I going wrong ?

brother we didn't complete the test, so can't view that question right now, So,comment on the question, after completing the test, someone will check that comment and reply

(ii) is true only when allocation order is strictly increasing order but it is false if allocation order is strictly decreasing. So (ii) should be false, as it includes the word "never".

When full length test series from GATEBOOK will be available?
