ajax call you can check through fiddler(or any debugger). it will show the request and response clearly.
and also, if the selecting states is an ajax call, then it will never use the cached data.

Asked In :-
SenecaGlobal IT Services, Isolve Technologies, Fulcrum Logic (I), WinWire Technologies, GoFrugal Technologies, Hanu Software Solutions, iProgrammer, NovoInvent, Caprus IT, Alcor Solutions,
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 are service endpoints and private endpoints in Azure networking
Asked In :-
SenecaGlobal IT Services, Anlage Infotech (I), Fulcrum Logic (I), Stridely Solutions, PreludeSys India, Savantis, 159 Solutions, Astoria Technologies, Solunus, Accucia,
Right Answer:
Service endpoints in Azure networking allow you to secure your Azure services to your virtual network by providing direct connectivity to Azure services over an optimized route, enhancing security and performance.
Private endpoints, on the other hand, are a network interface that connects you privately and securely to a service powered by Azure Private Link. This allows you to access Azure services over a private IP address within your virtual network, ensuring that traffic does not traverse the public internet.

Ques:- What is Azure VPN Gateway and how does it work with ExpressRoute
Asked In :-
TNQ Technologies, Spark Infosys, eGain Communications, Sanitation Districts of Los Angeles County, Capital Numbers, Alcor Solutions, Raptor Supplies, Sarla Technologies Pvt Ltd, psg global solutions, sovos,
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:- What is Azure Active Directory and how is it used for identity management
Asked In :-
SenecaGlobal IT Services, Isolve Technologies, Omnie Solutions (I), ARMIA SYSTEMS, BHP, ACS IT SOLUTIONS, Eidiko Systems Integrators, 159 Solutions, OneOrigin, IRIS Software Group,
Right Answer:
Azure Active Directory (Azure AD) is a cloud-based identity and access management service from Microsoft. It helps organizations manage user identities and access to resources securely. Azure AD is used for single sign-on (SSO), multi-factor authentication (MFA), and managing user permissions for applications and services in the cloud and on-premises.

Ques:- How do you manage state in mobile applications
Asked In :-
Startup - Navya Network, SPARX IT SOLUTIONS, SWYM, Happiest Minds Technologies Pvt., scandid, Pinnacleworks Infotech, CaratLane, Mobio Solutions, Sarvaha Systems, BillDesk,
Right Answer:
State in mobile applications can be managed using various methods such as:
1. **Local State Management**: Using component state in frameworks like React Native or local variables in native apps.
2. **Global State Management**: Utilizing libraries like Redux, MobX, or Context API for sharing state across components.
3. **Persistent Storage**: Storing state in local storage, SQLite, or using AsyncStorage for React Native to maintain state across app sessions.
4. **Server State Management**: Fetching and synchronizing state with a backend server using APIs.
5. **Navigation State**: Managing state related to navigation using libraries like React Navigation or native navigation components.
