Right Answer:
IaaS (Infrastructure as a Service) provides virtualized computing resources over the internet, allowing users to manage operating systems and applications. PaaS (Platform as a Service) offers a platform allowing developers to build, deploy, and manage applications without worrying about the underlying infrastructure. SaaS (Software as a Service) delivers software applications over the internet on a subscription basis, where users access the software without managing the infrastructure or platform.
Ques:- What is Azure DNS and how is it used for domain management
Right Answer:
Azure DNS is a cloud-based domain name system service provided by Microsoft Azure that allows you to host your DNS domains and manage DNS records. It enables you to resolve domain names to IP addresses and provides features like high availability, scalability, and security for your domain management needs. You can use Azure DNS to create and manage DNS zones, records, and integrate with other Azure services for seamless domain management.
Ques:- What are Managed Disks in Azure and what are their benefits
Right Answer:
Managed Disks in Azure are a storage option that simplifies disk management for Azure Virtual Machines (VMs). They are managed by Azure, meaning that Azure handles the storage accounts, scaling, and redundancy for you.

Benefits of Managed Disks include:
1. Simplified management: No need to manage storage accounts.
2. Scalability: Easily scale up to thousands of disks.
3. High availability: Built-in redundancy and availability options.
4. Improved performance: Optimized for better I/O performance.
5. Enhanced security: Supports encryption at rest and in transit.
Ques:- What is Azure Resource Manager and how does it manage resources
Right Answer:
Azure Resource Manager (ARM) is a management framework in Microsoft Azure that allows users to deploy, manage, and organize Azure resources. It provides a consistent management layer through which resources can be created, updated, and deleted in a unified manner. ARM uses resource groups to organize resources, enabling easier management, access control, and deployment of applications.
Ques:- What is Azure VPN Gateway and how does it work with ExpressRoute
Right Answer:
Azure VPN Gateway is a service that allows you to create secure, cross-premises connections between your on-premises networks and Azure virtual networks over the internet. It uses industry-standard protocols such as IKEv2 and IPsec to establish secure tunnels.

ExpressRoute, on the other hand, provides a private connection between your on-premises infrastructure and Azure, bypassing the public internet. While both services enable hybrid connectivity, Azure VPN Gateway is typically used for secure connections over the internet, whereas ExpressRoute offers a more reliable and faster connection with lower latency and higher security. They can be used together in scenarios where you need both secure internet-based connections and private connections to Azure.
Ques:- How do you monitor risks to the project and mitigate them?
Right Answer:
I monitor risks by regularly reviewing the risk register, conducting risk assessments, and holding team meetings to discuss potential issues. To mitigate risks, I develop response plans, prioritize risks based on their impact and likelihood, and implement strategies such as avoidance, transfer, acceptance, or mitigation. I also track the effectiveness of these strategies and adjust them as necessary throughout the project lifecycle.
Ques:- What is a mapping in plc & dcs
Right Answer:
In PLC (Programmable Logic Controller) and DCS (Distributed Control System), mapping refers to the process of defining how input and output signals from field devices (like sensors and actuators) are assigned to specific addresses or variables in the control system. This allows the control system to correctly interpret and manage the data from these devices for monitoring and control purposes.

Ques:- What is your approach to handling mismatches between ARXML versions
Right Answer:
To handle mismatches between ARXML versions, I would first identify the differences in the schema and data elements between the versions. Then, I would update the integration tools and scripts to accommodate these changes, ensuring backward compatibility where possible. Additionally, I would collaborate with stakeholders to validate the updated ARXML files and perform thorough testing to ensure that the system functions correctly with the new version. Finally, I would document the changes and provide training if necessary to ensure smooth adoption.
