Which of the following are the primary objectives of risk monitoring in software project tracking?
$P$: To assess whether predicted risks do, in fact, occur
$Q$: To ensure that risk aversion steps defined for the risk are being properly applied
$R$: To collect information that can be used for future risk analysis
Solution
Risk monitoring is used to track risks during a software project.
It checks whether predicted risks actually occur.
It also checks whether risk avoidance or risk reduction steps are being applied properly.
It also collects risk-related information so that it can be used in future risk analysis.
Therefore, all $P,Q,R$ are correct.
Software validation mainly checks for inconsistencies between:
Solution
Software validation checks whether the software specification actually satisfies the user's real requirements.
It answers the question:
Are we building the right product?
So, validation mainly checks inconsistencies between detailed specifications and user requirements.
| List-I (Testing Type) | List-II (Description) |
| A. Unit testing | I. Testing individual components of the software |
| B. Integration testing | II. Testing the interaction between integrated components |
| C. System testing | III. Testing to verify the system meets business needs |
| D. Acceptance testing | IV. Testing the complete system to ensure it meets requirements |
Choose the correct answer from the options given below.
Solution
Unit Testing → Testing individual components
Integration Testing → Testing interaction between modules
System Testing → Testing the complete system
Acceptance Testing → Verifying business/user requirements
Thus mapping:
A → I
B → II
C → IV
D → III
Which of the following is not one of the principles of good coding?
Solution
Solution
Solution
(A) It controls efforts.
(B) It controls resources.
(C) It controls cost of development.
Choose the correct answer from the options given below:
Solution
Fourth Generation Technique $(4GT)$ is a software development approach that uses high-level tools and languages.
It helps in faster software development because less manual coding is required.
Now check each statement:
(A) It controls efforts.
This is correct because $4GT$ reduces manual programming effort.
(B) It controls resources.
This is also correct because fewer resources may be needed due to automation and high-level tools.
(C) It controls cost of development.
This is also correct because reduced effort and better resource usage reduce development cost.
Therefore, all statements are correct.
Solution
Solution
In a system for a restaurant, the main scenario for placing an order is given below:
(a) Customer reads menu
(b) Customer places order
(c) Order is sent to the kitchen for preparation
(d) Ordered items are served
(e) Customer requests for a bill for the order
(f) Bill is prepared for this order
(g) Customer is given the bill
(h) Customer pays the bill
A sequence diagram for the scenario will have at least how many objects among whom the messages will be exchanged.
Solution
In this restaurant ordering system, the minimum important objects are:
Customer
Menu
Order
Kitchen
Bill
Messages are exchanged among these objects during order placement, food preparation, serving, bill generation and payment.
So, at least $5$ objects are required in the sequence diagram.
