Verification & Validation Engineer Interview Questions and Answers

BGP and OSPF are routing protocols used in networking. BGP has states like Idle, Connect, OpenSent, etc. OSPF has states like Down, Init, 2-Way, etc.

• BGP states: Idle, Connect, OpenSent, OpenConfirm, Established

• OSPF states: Down, Init, 2-Way, ExStart, Exchange, Loading, Full

• To configure label path in BGP, you can use the 'mpls label protocol ldp' command in Cisco IOS

• To configure BGP peering, you need to define neighbor relationships using the 'neighbor' command in BGP configur...read more

Frequency analyzers, CROs, and signal generators are essential tools for verifying and validating electronic systems.

• Frequency analyzers are used to measure the frequency of signals in electronic systems.

• CROs (Cathode Ray Oscilloscopes) are used to visualize and analyze the waveform of signals.

• Signal generators are used to generate specific waveforms or frequencies for testing electronic systems.

• These tools are crucial for ensuring the proper functioning and performance of el...read more

Current can be measured using an ammeter and voltage can be measured using a voltmeter.

• Use an ammeter to measure current flowing through a circuit

• Connect the ammeter in series with the circuit

• Use a voltmeter to measure the potential difference across a component

• Connect the voltmeter in parallel with the component

• Ensure proper units are used for measurement (Amps for current, Volts for voltage)

My engineering subjects focused on systems design, software testing, and quality assurance methodologies for effective validation.

• Studied Software Engineering principles, emphasizing the importance of requirements gathering and design specifications.

• Learned about various testing methodologies, including unit testing, integration testing, and system testing.

• Gained hands-on experience with tools like JIRA and Selenium for tracking defects and automating tests.

• Explored risk mana...read more

Static is used in programming to declare variables and functions that are accessible only within the same file.

• Static keyword is used to declare variables and functions with a local scope.

• Static variables retain their values between function calls.

• Static functions can only be called within the same file where they are declared.

• Static keyword can also be used in classes to create class-level variables and functions.

Stale Element Exception occurs when a web element is no longer attached to the DOM.

• Occurs in Selenium when the referenced element is no longer valid.

• Commonly happens after page refresh or DOM updates.

• Example: Clicking a button that triggers a page reload.

• Solution: Re-locate the element after the DOM change.

I have worked on various projects involving verification and validation of software systems to ensure they meet requirements and standards.

• Led testing efforts to verify software functionality and performance

• Developed test plans and test cases based on requirements

• Analyzed test results and reported findings to stakeholders

• Collaborated with developers to resolve issues and improve software quality
