Answer 1: Shortest Path Algorithms
- Correct Answer: All (I), (II) and (III)
- Explanation: All three are standard algorithms for finding shortest paths in a graph. Dijkstra's and Bellman-Ford calculate single-source shortest paths, while Floyd-Warshall calculates all-pairs shortest paths.
Answer 2: Recursive Function Output
- Correct Answer: Program Crashes
- Explanation: The base case for the recursive function is exactly n == 0. If you pass -1, the function bypasses the base case and calls sum(-2), which calls sum(-3), and so on indefinitely. This infinite recursion will eventually cause a stack overflow and crash the program.
Answer 3: Concurrent Development Model
- Correct Answer: Allows representation of concurrent elements in any process models, facilitating parallel development activities
- Explanation: The concurrent development model (often called concurrent engineering) is designed to allow different phases of software development to happen simultaneously, rather than strictly sequentially, which speeds up the development process.
Answer 4: Object-Oriented Hypermedia Design Method (OOHDM)
- Correct Answer: Class diagrams and aggregation creation
- Explanation: The first phase of OOHDM is Conceptual Design, which focuses on building a structural model of the application domain using standard object-oriented principles, such as defining classes, relationships, and aggregations.
Answer 5: PowerShell Execution Policy
- Correct Answer: To allow or restrict the execution of PowerShell scripts.
- Explanation: The execution policy is a safety feature in PowerShell that controls the conditions under which configuration files are loaded and scripts are run, helping to prevent the execution of malicious code.
Answer 6: Cross-point switch
- Correct Answer: 45
- Explanation: In a full-duplex system where any two lines can communicate in both directions using a single connection, and there are no self-connections, the number of unique pairs (cross-points) for N lines is calculated using the formula Answer-: N(N-1)/2
- Answer. For 10 lines, this is Answer-: {10*9}/2 = 45
