Troubleshooted network and server issues
Implemented disaster recovery plans
Monitored and optimized data center performance
Components inside a server include CPU, RAM, hard drives, power supply, motherboard, and network interface cards.
CPU (Central Processing Unit) - processes instructions and performs calculations
RAM (Random Access Memory) - stores data and instructions that the CPU needs
Hard drives - store data and programs long-term
Power supply - provides electricity to the server components
Motherboard - connects all the components toge...
Before turning off a server, it is important to properly shut down all running applications and services to prevent data loss or corruption.
Save any work in progress and close all applications
Ensure all services are stopped gracefully
Check for any pending updates or patches
Backup important data if necessary
Notify users or stakeholders about the planned shutdown
Document the shutdown process for future reference
Different types of optical cables include single-mode fiber, multi-mode fiber, and plastic optical fiber.
Single-mode fiber: used for long-distance communication, has a small core size and transmits infrared laser light.
Multi-mode fiber: used for shorter distances, has a larger core size and transmits infrared LED light.
Plastic optical fiber: used for short-distance applications like home networks, made of plastic inste
Troubleshooting network issues involves identifying the problem, gathering information, isolating the cause, and implementing a solution.
Identify the problem by gathering information from users and monitoring tools
Isolate the cause by checking network configurations, hardware, and software
Implement a solution by making necessary changes and testing the network
Document the troubleshooting process for future reference
I use tools like optical power meters, visual fault locators, and OTDRs to check optical fiber.
Optical power meters measure the power level of the optical signal.
Visual fault locators help identify breaks or bends in the fiber.
OTDRs (Optical Time Domain Reflectometers) analyze the quality of the fiber by sending pulses of light and measuring reflections.

I was interviewed in Mar 2017.
To make the red fishes 98%, 50 fishes have to be removed from the aquarium.
Calculate 1% of 200 fishes, which is 2 fishes.
To make the red fishes 98%, subtract 1% (2 fishes) from 99% (198 fishes).
To find the number of fishes to be removed, divide the difference by 1% (2 fishes).
Therefore, 50 fishes have to be removed to make the red fishes 98%.

I applied via Naukri.com and was interviewed in Aug 2023. There were 3 interview rounds.
A bug in an application is an error, flaw, failure, or fault in the software code that causes it to produce incorrect or unexpected results.
Bugs can range from simple syntax errors to complex logic issues.
Common types of bugs include logic errors, syntax errors, and runtime errors.
Examples of bugs include a calculator app displaying incorrect results, a website crashing when a specific button is clicked, or a game free
Bug life cycle includes identification, reporting, fixing, retesting, and closing.
Identification: Bug is identified by testers during testing.
Reporting: Testers report the bug to developers.
Fixing: Developers fix the bug in the code.
Retesting: Testers retest the fixed bug to ensure it is resolved.
Closing: Once bug is confirmed fixed, it is closed.
