Storages can be classified into three types: direct-attached, network-attached, and storage area networks.

• Direct-attached storage (DAS) is directly connected to a server or computer, such as a hard drive or USB drive.

• Network-attached storage (NAS) is a file-level storage connected to a network, allowing multiple users to access the same data simultaneously.

• Storage area networks (SAN) are block-level storage connected to a network, providing high-speed access to data for serve...read more

Data annotation is the process of labeling data to make it understandable for machines.

• Data annotation involves adding metadata to raw data.

• It is used to train machine learning models.

• Examples include labeling images with object names or sentiment analysis of text.

• It can be done manually or with the help of tools like Labelbox or Amazon Mechanical Turk.

Steps for DR test, storage migration, SAN issue mitigation, and identifying slow draining devices.

• DR test: Define scope, select test type, prepare test environment, execute test, evaluate results.

• Storage migration: Plan migration, validate source and destination, perform migration, verify data integrity.

• Inter-site migration: Use replication tools, verify data consistency, update DNS records.

• Same site migration: Use storage vMotion, verify data integrity.

• SAN issue mitigation: ...read more

Reports can be generated in TestNG using the built-in reporting feature or by using third-party plugins.

• TestNG provides built-in HTML reports that can be generated after test execution

• Custom reports can be generated using TestNG listeners and report generation APIs

• Third-party plugins like ExtentReports and ReportNG can also be used for advanced reporting

• Reports can be customized with logos, headers, footers, and other formatting options

Insurance is a contract between an individual and an insurance company to protect against financial loss.

• Insurance provides financial protection against unexpected events

• Individuals pay premiums to an insurance company in exchange for coverage

• Types of insurance include health, auto, home, and life insurance

• Insurance policies have terms and conditions that outline what is covered and what is not

• Insurance companies use actuarial science to calculate risk and set premiums

Cyber attacks can be classified into various types based on their methods and targets.

• Malware attacks (e.g. viruses, worms, trojans)

• Phishing attacks (e.g. social engineering, email scams)

• Denial of Service (DoS) attacks

• Man-in-the-middle (MitM) attacks

• SQL injection attacks

• Cross-site scripting (XSS) attacks

• Advanced Persistent Threats (APTs)

• Ransomware attacks

• Cryptojacking attacks

• IoT-based attacks

• Password attacks (e.g. brute force, dictionary attacks)

Updating solutions can sometimes lead to problems.

• Updating solutions may cause compatibility issues with other software or hardware.

• There may be unforeseen bugs or errors that arise after the update.

• The update may require additional resources or training for users to properly utilize.

• Testing and quality assurance are crucial to ensure a successful update.

• Regular updates are necessary to ensure security and functionality.

Production support involves maintaining and troubleshooting software applications in a live environment.

• Monitoring application performance and availability

• Resolving technical issues and bugs reported by users

• Implementing hotfixes and patches to address critical issues

• Performing regular maintenance tasks to ensure system stability

• Providing technical support to end users

BDD is a software development methodology that focuses on collaboration between developers, testers, and business stakeholders.

• BDD stands for Behavior Driven Development

• It emphasizes on defining the behavior of the system in plain English language

• Uses Gherkin syntax to write scenarios in Given-When-Then format

• Helps in improving communication and collaboration between teams

• Tools like Cucumber and SpecFlow are used for BDD implementation

Migrating NAS resources involves planning, testing, and executing the migration process.

• Identify the data to be migrated and the target storage system

• Plan the migration process, including downtime and data transfer methods

• Test the migration process in a non-production environment

• Execute the migration process, monitor progress, and verify data integrity

• Update any necessary configurations and test the new storage system

Azure AD is a cloud-based identity and access management service.

• Provides single sign-on (SSO) to various cloud-based and on-premises applications

• Offers multi-factor authentication (MFA) and conditional access policies

• Integrates with other Microsoft services like Office 365 and Azure

• Allows for user and group management, as well as device management

Dependency injection is a design pattern used to remove hard-coded dependencies and make components more modular and testable.

• Constructor injection: Dependencies are provided through a class's constructor.

• Setter injection: Dependencies are set through setter methods.

• Interface injection: Dependencies are injected through an interface.

• Spring framework in Java uses dependency injection to manage components.

• Angular framework in JavaScript also utilizes dependency injection for ma...read more

I have used a variety of tools in my previous organization to support BI production.

• ETL tools like Informatica and Talend

• Monitoring tools like Splunk and Nagios

• Ticketing tools like JIRA and ServiceNow

SIEM tools are security information and event management tools used to collect, analyze and correlate security events.

• SIEM tools help in detecting and responding to security incidents

• They collect data from various sources like firewalls, IDS/IPS, and endpoints

• SIEM tools use correlation rules to identify potential security threats

• Examples of SIEM tools include Splunk, IBM QRadar, and ArcSight

Event loop is a mechanism in JavaScript that allows for asynchronous operations to be executed in a non-blocking way.

• Event loop is responsible for handling asynchronous operations in JavaScript.

• It continuously checks the call stack and the callback queue to see if there are any tasks to be executed.

• Tasks from the callback queue are moved to the call stack for execution when the call stack is empty.

• Event loop ensures that JavaScript remains single-threaded and non-blocking.
