AGS Transact Technologies Software Engineer Interview Questions and Answers

Splunk has a hierarchy of knowledge objects that includes apps, add-ons, and configurations.

• The highest level is the app, which contains all other knowledge objects.

• Add-ons are installed within apps and provide additional functionality.

• Configurations are specific to an app or add-on and include saved searches, alerts, and dashboards.

Configuring a cluster involves setting up multiple servers to work together as a single system.

• Choose a cluster management software such as Kubernetes or Apache Mesos

• Select the appropriate hardware and network infrastructure

• Install and configure the cluster management software on each server

• Define the roles and responsibilities of each server in the cluster

• Test the cluster to ensure it is functioning properly

Rsyslog is configured by editing its configuration file, usually located at /etc/rsyslog.conf

• Edit the configuration file using a text editor

• Specify the log files to be monitored and the actions to be taken for each log message

• Configure filters to select specific log messages based on criteria such as severity or facility

• Specify the destination for the log messages, such as a file, remote server, or database

• Restart the

Splunk has a hierarchy of knowledge objects to organize and manage data.

• The hierarchy includes apps, add-ons, and configurations.

• Apps contain dashboards, reports, and alerts.

• Add-ons provide additional functionality to apps.

• Configurations include indexes, sourcetypes, and fields.

• Knowledge objects can be shared across the hierarchy.

• Higher level objects inherit settings from lower level objects.

Configuring a cluster involves setting up multiple servers to work together as a single system.

• Choose a cluster management tool such as Kubernetes or Apache Mesos

• Determine the number of nodes and their roles in the cluster

• Configure network settings and communication protocols

• Set up load balancing and failover mechanisms

• Ensure data consistency and replication across nodes

Rsyslog is configured by editing its configuration file, usually located at /etc/rsyslog.conf

Detecting loop in a linked list

• Use two pointers, one moving one node at a time and the other moving two nodes at a time

• If there is a loop, the two pointers will eventually meet

• If any of the pointers reach the end of the list, there is no loop

DFS (Depth-First Search) is a graph traversal algorithm that explores as far as possible along each branch before backtracking.

• DFS uses a stack to keep track of visited nodes and explore adjacent nodes.

• It can be implemented recursively or iteratively.

• DFS is useful for solving problems like finding connected components, detecting cycles, and solving mazes.

To find a cycle in a graph, use depth-first search (DFS) and keep track of visited nodes.

• Implement DFS algorithm to traverse the graph

• Maintain a visited array to keep track of visited nodes

• If a visited node is encountered again during DFS, a cycle exists

Hashing is a process of converting data into a fixed-size numerical value called a hash code.

• Hashing is used to quickly retrieve data from large datasets.

• It is commonly used in data structures like hash tables and hash maps.

• Hash functions should be fast, deterministic, and produce unique hash codes for different inputs.

• Examples of hash functions include MD5, SHA-1, and SHA-256.

The question asks for the number of pairs between 1 and N that satisfy a specific mathematical relation.

• The relation is pow(a,3) + pow(b,3) = pow(c,3) + pow(d,3)

• The values of a, b, c, and d should be less than or equal to N

• Count the number of pairs that satisfy the relation

Merge sort is a divide-and-conquer algorithm that recursively divides an array into two halves, sorts them, and then merges them.

• Divide the array into two halves

• Recursively sort each half

• Merge the sorted halves back together

• Repeat until the entire array is sorted
