Solution
Solution
Software validation checks whether the software meets the requirements and expectations of the customer.
| List-I | List-II |
| A. Verification | I. White box Testing |
| B. Validation | II. Black box Testing |
| C. Internal logic exercise | III. Quality Control |
| D. Software requirement exercise | IV. Quality Assurance |
Solution
Verification → Quality Assurance → IV
Validation → Quality Control → III
Internal logic exercise → White box testing → I
Software requirement exercise → Black box testing → II
Matching:
A → IV
B → III
C → I
D → II
(A) Execution Time
(B) Calendar Time
(C) Clock Time
Choose the correct answer from the options given below:
Solution
So, all A, B and C are correct.
(A) Evaluates all use-cases
(B) Builds state transition diagram for the system.
(C) Reviews the object behaviour model to verify accuracy and consistency
(D) Identifies events that do not derive the interaction sequence.
Choose the correct answer from the options given below:
Solution
State transition diagram is also built to show object states and transitions.
The model is reviewed for accuracy and consistency.
Statement D is not correct as written, because events should drive the interaction sequence, not “do not derive” it.
Solution
Cost Performance Index is calculated as:
$CPI = \frac{BCWP}{ACWP}$
That means:
Budgeted cost of work performed ÷ Actual cost of work performed
(A) Equivalence Partitioning
(B) Graph-Based Testing Method
(C) Boundary Value Analysis
(D) Data flow Testing
(E) Loop Testing
Choose the correct answer from the options given below:
Solution
Equivalence partitioning is a black-box testing technique.
Graph-based testing method is also a behavioral testing technique.
Boundary value analysis is also a black-box testing technique.
Data flow testing and loop testing are white-box testing techniques.
Therefore, A, B and C only are correct.
Solution
Number of transactions per second:
$ \frac{20000}{120} = 166.67 $
Size of each article:
$3k$ bytes $= 3000$ bytes
$3000$ bytes $= 3000 \times 8 = 24000$ bits
Throughput:
$166.67 \times 24000 = 4000000$ bits per second
$= 4$ megabits per second
| LIST I | LIST II |
| A. Scenario testing | I. To verify the I/O behavior of text object |
| B. Regression testing | II. User acceptance methodology |
| C. Component testing | III. No new bugs after changes in program |
| D. Beta testing | IV. The documentation of a use case |
Choose the correct answer from the options given below:
Solution
| LIST I | LIST II |
| A. PERT | I. Used for non repetitive jobs |
| B. Optimistic time | II. Used for repetitive jobs |
| C. CPM | III. The shortest possible time to complete the activity if all goes well |
| D. Pessimistic time | IV. The longest time that an activity takes |
Choose the correct answer from the options given below:
Solution
PERT is used for non repetitive jobs.
Optimistic time means the shortest possible time if everything goes well.
CPM is used for repetitive jobs.
Pessimistic time means the longest possible time an activity may take.
So,
A – I, B – III, C – II, D – IV
