Ques:- Why do you use stored procedures and what is their main functionality in a RDBMS?
Right Answer:
Stored procedures are used to encapsulate complex SQL queries and business logic in a reusable way. Their main functionalities in a RDBMS include improving performance by reducing network traffic, enhancing security by controlling access to data, ensuring consistency through centralized logic, and simplifying maintenance by allowing changes in one place without affecting application code.
Ques:- Can you describe a time when a cross-sell didn’t go well? What did you learn?
Right Answer:

In a previous role, I attempted to cross-sell a premium service to a customer who was primarily focused on cost. The customer felt overwhelmed and pressured, leading to frustration and a negative experience. I learned the importance of understanding the customer's needs and timing the cross-sell appropriately, ensuring it aligns with their priorities rather than pushing for a sale.

Ques:- What is a payment gateway and how does it function
Right Answer:
A payment gateway is a service that processes online payments for e-commerce transactions. It securely transmits customer payment information from the website to the payment processor and then returns the transaction results back to the website. It functions by encrypting sensitive data, authorizing payments, and ensuring that funds are transferred from the customer's account to the merchant's account.
Ques:- What is inventory management in an e commerce setting
Right Answer:
Inventory management in an e-commerce setting refers to the process of overseeing and controlling the stock of products available for sale. It involves tracking inventory levels, managing stock replenishment, forecasting demand, and ensuring that products are available to meet customer orders while minimizing excess stock and associated costs.
Ques:- How do you incorporate feedback to improve your cross-selling approach?
Right Answer:

I incorporate feedback by regularly reviewing customer interactions, analyzing sales data, and seeking input from colleagues. I identify patterns in what works and what doesn’t, adjust my strategies accordingly, and continuously test new approaches to enhance my cross-selling effectiveness.

Ques:- How do you manage logistics and shipping in e commerce
Right Answer:
To manage logistics and shipping in e-commerce, I would:

1. Choose reliable shipping partners and negotiate rates.
2. Implement an inventory management system to track stock levels.
3. Use a centralized order management system to streamline order processing.
4. Offer multiple shipping options to customers.
5. Monitor shipping performance and customer feedback to optimize the process.
6. Ensure clear communication with customers regarding shipping times and tracking.
Ques:- How do you monitor cloud infrastructure (AWS, Azure, GCP)?
Right Answer:

To monitor cloud infrastructure in AWS, Azure, or GCP, you can use the following tools:

– **AWS**: Amazon CloudWatch for metrics and logs, AWS CloudTrail for API activity, and AWS Config for resource configuration tracking.
– **Azure**: Azure Monitor for performance and health metrics, Azure Log Analytics for log data, and Azure Security Center for security monitoring.
– **GCP**: Google Cloud Monitoring for resource metrics, Google Cloud Logging for log management, and Google Cloud Operations Suite for overall monitoring and management.

Additionally, third-party tools like Datadog, New Relic, or Prometheus can also be integrated for comprehensive monitoring across multiple cloud platforms.

Ques:- How would you set up an alerting escalation policy?
Right Answer:

To set up an alerting escalation policy, follow these steps:

1. **Define Alert Criteria**: Identify the conditions that trigger alerts (e.g., CPU usage, downtime).
2. **Set Alert Severity Levels**: Classify alerts by severity (e.g., critical, warning, info).
3. **Establish Notification Channels**: Decide how alerts will be communicated (e.g., email, SMS, chat).
4. **Create Escalation Paths**: Outline who gets notified first and who to escalate to if the issue isn’t resolved within a set timeframe.
5. **Set Response Timeframes**: Define how quickly each level of escalation should respond.
6. **Document the Process**: Ensure all team members understand the escalation policy.
7. **Test the Policy**: Regularly test the alerting system to ensure it works as intended.
8. **Review and Adjust**: Periodically review the policy for effectiveness and make adjustments as necessary.

Ques:- What are false positives/negatives in monitoring, and how do you reduce them?
Right Answer:

False positives in monitoring occur when an alert is triggered for an issue that isn't actually present, while false negatives happen when a real issue exists but no alert is triggered. To reduce them, you can fine-tune alert thresholds, implement better anomaly detection algorithms, use correlation rules to filter out noise, and regularly review and adjust monitoring configurations based on historical data and trends.

Ques:- How do you define thresholds and alerts for monitored systems?
Right Answer:

Thresholds and alerts for monitored systems are defined by identifying key performance indicators (KPIs) and setting specific values that indicate normal and abnormal performance. Thresholds are established based on historical data, industry standards, and business requirements. Alerts are configured to trigger notifications when metrics exceed or fall below these thresholds, allowing for timely responses to potential issues.

Ques:- What is SNMP and how is it used in network monitoring?
Right Answer:

SNMP, or Simple Network Management Protocol, is a protocol used for managing and monitoring network devices. It allows network administrators to collect and organize information about devices such as routers, switches, and servers, and to manage their performance and configuration. SNMP operates by using a manager to request data from agents on the devices, which respond with the requested information, enabling effective network monitoring and management.
