I appeared for an interview in Oct 2024, where I was asked the following questions.
Firmware upgrades enhance device performance, security, and compatibility, while RMA ensures efficient replacement of faulty switches.
Improved Performance: Upgrading firmware can optimize the performance of network devices, such as switches, by enhancing processing capabilities.
Security Enhancements: Firmware updates often include patches for vulnerabilities, protecting the network from potential threats.
New Features: ...

The 3-way handshake is a TCP connection establishment process involving SYN, SYN-ACK, and ACK messages.
Step 1: Client sends a SYN packet to the server to initiate a connection.
Step 2: Server responds with a SYN-ACK packet to acknowledge the request.
Step 3: Client sends an ACK packet back to the server, completing the handshake.
Example: A web browser (client) connects to a web server using this process.
SSL (Secure Sockets Layer) is a protocol for establishing a secure, encrypted link between a web server and a browser.
SSL encrypts data transmitted over the internet, ensuring privacy and security.
It uses a combination of asymmetric and symmetric encryption for secure communication.
Websites using SSL have URLs that start with 'https://' instead of 'http://'.
SSL certificates are issued by Certificate Authorities (CAs) t...
ZCC stands for Zero-Crossing Control, a technique used in electronic circuits for efficient switching.
ZCC minimizes power loss during switching events.
Commonly used in AC motor drives to improve efficiency.
Helps reduce electromagnetic interference (EMI) in circuits.
Example: In a TRIAC-based dimmer switch, ZCC ensures smooth light dimming.
The OSI model is a conceptual framework used to understand network communication in seven layers.
Layer 1: Physical - Deals with the physical connection (e.g., cables, switches).
Layer 2: Data Link - Manages node-to-node data transfer (e.g., Ethernet, Wi-Fi).
Layer 3: Network - Handles routing and forwarding of data packets (e.g., IP).
Layer 4: Transport - Ensures complete data transfer (e.g., TCP, UDP).
Layer 5: Session - ...
A VPN (Virtual Private Network) creates a secure connection over the internet, protecting data and privacy.
Encrypts internet traffic to protect data from eavesdroppers.
Allows remote access to a private network, useful for telecommuting.
Bypasses geo-restrictions, enabling access to region-locked content.
Examples include services like NordVPN, ExpressVPN, and Cisco AnyConnect.

Device bias can lead to improved performance, efficiency, and user experience in network engineering.
Device bias can result in optimized network traffic routing, leading to faster data transmission.
It can enhance security measures by prioritizing certain devices for access control and monitoring.
Device bias can improve overall network stability and reliability by allocating resources more effectively.
For example, imple...

Hashtable is synchronized while hashmap is not.
Hashtable is thread-safe while hashmap is not.
Hashtable does not allow null keys or values while hashmap allows one null key and multiple null values.
Hashtable is slower than hashmap due to synchronization.
Hashtable is a legacy class while hashmap is a newer implementation.
Hashmap is not thread-safe while Concurrent Hashmap is thread-safe.
Hashmap is not suitable for multi-threaded environments as it can lead to race conditions and data inconsistencies.
Concurrent Hashmap allows multiple threads to access and modify the map concurrently without any data inconsistencies.
Concurrent Hashmap uses a technique called lock striping to achieve thread-safety.
Concurrent Hashmap is slower than Hashma...
