Tata Elxsi Interview Questions, Process, and Tips

Quantization is the process of mapping input values from a continuous range to a discrete set of values. Convolution is a mathematical operation that combines two functions to produce a third function.

• Quantization reduces the precision of data by mapping it to a smaller set of values. For example, converting a grayscale image from 256 levels to 8 levels.

• Convolution involves sliding one function over another and multipl...read more

Swapping two numbers without using a third variable

• Use arithmetic operations to swap values

• Example: a = 5, b = 10; a = a + b; b = a - b; a = a - b;

• Ensure no overflow or underflow occurs

Using CUDA to multiply two matrices efficiently.

• Allocate memory on GPU for matrices A, B, and C

• Copy matrices A and B from host to device

• Launch CUDA kernel to perform matrix multiplication

• Copy result matrix C from device to host

• Free memory on GPU

Merge two sorted arrays into a single sorted array.

• Create a new array to store the merged result

• Use two pointers to iterate through the two input arrays and compare elements

• Add the smaller element to the new array and move the pointer for that array forward

• Repeat until all elements from both arrays are merged

Transformer architecture is a deep learning model that uses self-attention mechanism to process sequential data.

• Transformer architecture consists of an encoder and a decoder.

• Self-attention mechanism allows the model to weigh the importance of different input tokens when making predictions.

• Transformer models have been widely used in natural language processing tasks such as machine translation and text generation.

VxRail, Vsan, NSX commands to verify IPsec tunnel

• For VxRail, use 'show ipsec sa' command to verify IPsec tunnel status

• For Vsan, use 'esxcli network ip connection list' command to check IPsec tunnel connections

• For NSX, use 'get vpn ipsec sa' command to view IPsec tunnel information

NSX-V/T can be upgraded using in-place upgrade, side-by-side upgrade, or hybrid upgrade methods.

• In-place upgrade involves upgrading the existing NSX-V/T deployment without replacing the hardware or virtual machines.

• Side-by-side upgrade involves deploying a new NSX-V/T instance alongside the existing one and migrating workloads.

• Hybrid upgrade combines elements of in-place and side-by-side upgrades, allowing for a phased...read more
