Amantya Technologies Senior Technical Lead Interview Questions and Answers

Spring injects dependencies through inversion of control and dependency injection.

• Spring uses inversion of control to manage objects and their dependencies.

• Dependencies are injected into a class through constructor injection, setter injection, or field injection.

• Spring container is responsible for creating and managing objects and their dependencies.

• Example: @Autowired annotation is used for dependency injection in Spr

Hibernate connects to the database using JDBC (Java Database Connectivity) API.

• Hibernate uses JDBC API to establish a connection to the database.

• It uses JDBC drivers to communicate with the database.

• Hibernate configuration file contains database connection details.

• SessionFactory in Hibernate is responsible for creating sessions and managing connections.

Securing APIs involves using authentication, authorization, encryption, and monitoring.

• Implement authentication mechanisms such as OAuth, JWT, or API keys

• Use authorization to control access to APIs based on roles and permissions

• Encrypt data transmission using HTTPS/TLS to prevent eavesdropping

• Implement rate limiting and throttling to prevent abuse and DDoS attacks

• Regularly monitor API traffic and logs for suspicious ac

Multiple DBs can be configured in an application by using database connection pooling, configuring multiple data sources, and managing transactions across databases.

• Use database connection pooling to efficiently manage connections to multiple databases

• Configure multiple data sources in the application to connect to different databases

• Implement transaction management to ensure data consistency across multiple databases

Instant clone is a feature in VMware Horizon that allows for rapid creation of virtual desktops.

• Instant clones are created from a parent VM in a matter of seconds.

• They share the same virtual disks as the parent VM, but have their own memory and virtual NICs.

• Instant clones use a technology called VMFork to create a copy-on-write clone of the parent VM.

• They are ideal for use cases where a large number of identical virtua...read more

Primary and secondary connections with port numbers are used for communication between client and agent machines.

• Primary connection is established using a well-known port number, such as port 80 for HTTP.

• Secondary connection is established using a random port number, which is assigned by the client machine.

• Primary connection is used for initial communication and negotiation, while secondary connection is used for data ...read more

Writable volumes are used to store user or application data separately from the OS and applications.

• There are two types of writable volumes: User writable volumes and AppStack writable volumes.

• User writable volumes are used to store user-specific data and settings.

• AppStack writable volumes are used to store application-specific data and settings.

• Writable volumes can be created using VMware App Volumes or Citrix App Lay...read more

Instant clone creates a copy of the VM while linked clone shares virtual disks with the parent VM.

• Instant clone is faster to create than linked clone.

• Instant clone uses a copy-on-write mechanism to create a new VM.

• Linked clone shares virtual disks with the parent VM and only creates delta disks for changes.

• Instant clone is useful for creating many identical VMs quickly.

• Linked clone is useful for creating VMs with sligh
