Sample C-DAC C-CAT Practice Questions

Try these sample questions to review concepts for the C-DAC C-CAT exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Choose the word that is most nearly SYNONYMOUS with 'Diligent'.

A.Hard-working

B.Lazy

C.Careless

D.Clever

Explanation: 'Diligent' means showing care and conscientiousness in one's work or duties. Therefore, 'Hard-working' is the most appropriate synonym as it describes someone who puts constant, earnest effort into their tasks.

2Find the word that can substitute the phrase: 'A person who writes dictionaries'.

A.Lexicographer

B.Cartographer

C.Biographer

D.Calligrapher

Explanation: A lexicographer is a person who compiles or writes dictionaries, derived from the Greek 'lexikon' (dictionary) and 'graphia' (writing). The other options refer to different types of writers or map-makers.

3What is the meaning of the idiom 'To burn the midnight oil'?

A.To work or study late into the night

B.To waste oil or resources needlessly

C.To cause an accidental fire

D.To work in shifts during the night

Explanation: The idiom 'to burn the midnight oil' refers to using an oil lamp to work or study late into the night. It denotes working hard, particularly after normal working hours.

4Identify the correct version of the following sentence: 'Neither of the two candidates have completed their registration.'

A.Neither of the two candidates has completed their registration.

B.Neither of the two candidates has completed his or her registration.

C.Neither of the two candidates have completed his or her registration.

D.Neither of the two candidates had completed their registration.

Explanation: The pronoun 'neither' is singular and requires a singular verb ('has' instead of 'have'). Additionally, the singular pronoun 'his or her' must be used to agree with the singular subject.

5Fill in the blank with the appropriate preposition: 'The committee members differed _______ each other on the proposed strategy.'

A.from

B.with

C.at

D.by

Explanation: When 'differ' means to disagree in opinion, it is followed by the preposition 'with'. When referring to differences in physical qualities, it is followed by 'from'.

6Choose the correct passive voice version of the sentence: 'The manager scheduled a meeting for tomorrow morning.'

A.A meeting was scheduled by the manager for tomorrow morning.

B.A meeting is scheduled by the manager for tomorrow morning.

C.A meeting has been scheduled by the manager for tomorrow morning.

D.A meeting had been scheduled by the manager for tomorrow morning.

Explanation: The original sentence is in the simple past tense ('scheduled'). Converting it to passive voice requires 'was/were + past participle', making 'was scheduled' the correct verb form.

7Choose the correct indirect speech version of the sentence: 'She said, "I have been working on this project since yesterday."'

A.She said that she had been working on that project since the previous day.

B.She said that she has been working on this project since yesterday.

C.She said that she was working on that project since the previous day.

D.She said that she had worked on this project since the previous day.

Explanation: In indirect speech, the present perfect continuous ('have been working') changes to past perfect continuous ('had been working'). Demonstratives and time expressions like 'this' and 'yesterday' change to 'that' and 'the previous day'.

8Which of the following spellings is CORRECT?

A.Accommodation

B.Accomodation

C.Acommodation

D.Acomodation

Explanation: The correct spelling is 'Accommodation', containing two 'c's and two 'm's. It is derived from the Latin verb 'accommodare'.

9Read the passage and choose the best inference: 'While digital transformation offers efficiency gains, companies often fail to realize them. The bottleneck is rarely the technology itself; rather, it is the organizational culture that resists changing established workflows.' What is the primary inference?

A.Organizational resistance is the primary barrier to successful digital transformation.

B.New technology is usually flawed and causes project failures.

C.Employees need better training on technical tools to adapt.

D.Companies should avoid digital transformation due to the risks.

Explanation: The passage explicitly states that the bottleneck is 'rarely the technology itself' and is instead the 'organizational culture that resists changing established workflows.' This implies that human/organizational factors are the primary obstacle.

10Rearrange the sentences in the most logical order: P. Consequently, they are less likely to suffer from burnouts. Q. Regular exercise helps individuals manage stress levels. R. This is because physical activity releases endorphins. S. Endorphins are natural mood lifters that promote relaxation.

A.QRSP

B.QSRP

C.RQSP

D.PQRS

Explanation: Sentence Q introduces regular exercise. Sentence R explains why by introducing endorphins. Sentence S defines endorphins, and Sentence P states the final consequence. Thus, QRSP is the correct logical flow.
