Find Interview Questions for Mavenir systems

Right Answer:
Classical reports display data in a simple list format without user interaction, while interactive reports allow users to drill down into data, filter, and navigate through different levels of detail.

Right Answer:
Monitor using tools like JMX, Activiti Admin UI, and database monitoring tools. Scale horizontally by clustering Alfresco and databases, and by using caching mechanisms like Redis or Memcached.

Right Answer:
To debug ARM compiled code using tools like Keil or GDB, follow these steps:

1. **Compile with Debug Information**: Ensure your code is compiled with debug symbols enabled (use the `-g` flag for GCC or the appropriate setting in Keil).

2. **Load the Program**: Use Keil's uVision or GDB to load the compiled binary onto the target device or simulator.

3. **Set Breakpoints**: In Keil, set breakpoints using the GUI. In GDB, use the command `break <function_name>` or `break <line_number>`.

4. **Run the Program**: Start the execution of your program. In Keil, click the "Run" button; in GDB, use the command `run`.

5. **Step Through Code**: Use step commands to execute your code line by line (`step` or `next` in GDB).

6. **Inspect Variables**: Check variable values and memory

Right Answer:
A report in ABAP is a program that retrieves and displays data from the database in a structured format. The types of reports in ABAP are:

1. **Classical Reports**: These are basic reports that display data in a list format and allow simple user interactions.
2. **Interactive Reports**: These reports allow users to interact with the data, such as drilling down into details by clicking on specific entries.
3. **ALV Reports (ABAP List Viewer)**: These provide advanced features for displaying lists, including sorting, filtering, and exporting data.

Right Answer:

Declarative pipelines in Jenkins use a simplified syntax and are designed for ease of use, focusing on the overall structure of the pipeline. Scripted pipelines, on the other hand, use a more complex Groovy-based syntax, allowing for greater flexibility and control over the pipeline's behavior.

Right Answer:

To secure a CI/CD pipeline, implement the following measures:

1. **Access Control**: Use role-based access control (RBAC) to restrict permissions.
2. **Secrets Management**: Store sensitive information like API keys and passwords securely using secret management tools.
3. **Code Scanning**: Integrate static and dynamic code analysis tools to identify vulnerabilities.
4. **Dependency Management**: Regularly update and scan dependencies for known vulnerabilities.
5. **Environment Isolation**: Use separate environments for development, testing, and production.
6. **Audit Logs**: Enable logging and monitoring to track changes and access to the pipeline.
7. **Secure Communication**: Use HTTPS and secure protocols for data transmission.
8. **Automated Testing**: Implement automated tests to catch security issues early in the pipeline.
9. **Container Security**: If using containers, ensure images are scanned and use minimal base images.
10. **Regular Updates**: Keep CI/CD tools and infrastructure up to

Right Answer:

To monitor and alert on deployed applications, I would use tools like Prometheus for collecting metrics, Grafana for visualizing those metrics, and set up alerts based on specific thresholds. Additionally, I might use the ELK Stack for logging and searching logs, or Datadog/New Relic for comprehensive monitoring and alerting capabilities. Built-in cloud monitoring services can also be utilized for real-time insights and alerts.

Right Answer:

Infrastructure as Code (IaC) is a practice that allows you to define and manage your infrastructure using code. This means you can version, test, and deploy your infrastructure just like application code. In CI/CD, IaC fits in by enabling automated provisioning and management of infrastructure within the continuous integration and continuous deployment pipelines, ensuring consistency and reducing manual errors. Tools like Terraform and CloudFormation are commonly used for this purpose.

Right Answer:

Self-hosted runners are custom agents that execute CI/CD jobs on your own infrastructure rather than using cloud-hosted runners.

Right Answer:
Machine learning is a branch of artificial intelligence that enables computers to learn from data and improve their performance on tasks without being explicitly programmed.

Right Answer:
The CPU, or Central Processing Unit, is the main component of a computer that performs calculations and executes instructions, effectively acting as the brain of the computer.

Right Answer:
To retain the team member, I would have an open and honest conversation to understand their motivations and concerns. I would highlight their value to the team, discuss potential career growth opportunities, and explore non-monetary incentives such as professional development, flexible work arrangements, or additional responsibilities that align with their interests. Additionally, I would advocate for their contributions to senior management to seek possible budget adjustments or future salary reviews.

Right Answer:
The target for Fiscal deficit in budget 2017-18 was set at 3.2% of GDP.

Right Answer:
Communication is the process of exchanging information, ideas, or messages between individuals or systems through various means, such as speaking, writing, or using technology.

Right Answer:
Security risks associated with VoIP include eavesdropping, denial of service (DoS) attacks, toll fraud, and phishing. These can be mitigated by using encryption protocols like SRTP for voice data, implementing firewalls and intrusion detection systems, using strong authentication methods, and regularly updating software to patch vulnerabilities.

Right Answer:
To troubleshoot VoIP call quality issues, follow these steps:

1. **Check Network Performance**: Use tools to measure bandwidth, latency, jitter, and packet loss.
2. **Inspect Hardware**: Ensure that routers, switches, and VoIP phones are functioning properly and are not overloaded.
3. **Review QoS Settings**: Verify that Quality of Service (QoS) is configured to prioritize VoIP traffic.
4. **Examine Firewall Settings**: Ensure that firewalls are not blocking VoIP traffic or causing delays.
5. **Test with Different Devices**: Use different phones or softphones to determine if the issue is device-specific.
6. **Monitor Call Quality Metrics**: Analyze metrics like Mean Opinion Score (MOS) to identify specific quality issues.
7. **Check for Network Congestion**: Look for other applications consuming bandwidth during calls.
8. **Update Firmware and Software**: Ensure all VoIP devices and software are up to date.
9. **Conduct

Right Answer:
RTP (Real-Time Transport Protocol) is a network protocol used for delivering audio and video over IP networks. It supports voice communication by providing end-to-end delivery services for real-time data, including payload type identification, sequence numbering, timestamping, and delivery monitoring, which help ensure that voice packets are transmitted in the correct order and at the right time for smooth communication.

Right Answer:
Codecs affect voice quality in VoIP by compressing and decompressing audio signals. Different codecs use varying levels of compression, which can impact clarity, latency, and bandwidth usage. Higher-quality codecs provide better sound fidelity but may require more bandwidth, while lower-quality codecs may save bandwidth but can result in poorer audio quality.

Right Answer:
VoIP spoofing is when a caller disguises their identity by falsifying the caller ID information in VoIP communications. It can be prevented by implementing security measures such as using strong authentication methods, enabling encryption (like SRTP), employing firewalls, and utilizing intrusion detection systems to monitor and block suspicious activities.
