What is the function of the character analysis of API?
In the process of characterization of words, it doesn’t account for bad or good in the character analytics of API’s working. It means that the words considered are in neutral and not in some negative or positive sense in the process of working. An advanced feature is used in the process of characterization. The same advanced feature is also used in natural language processing.

Either one 0r 0 is used in the process of running. It is also called a binomial scoring unit. A negative viewpoint corresponds to 0, and a Positive viewpoint corresponds to 1. There is no need for training and designing assistance, and this is an advantage. Users can directly control the data in this process.
What are the actions to be taken in the service failure case?
These are the steps to be taken in the situation of failure of service:
- The removal of the drive-in case is not getting replaced. One can keep the system unmounted.
- Make the machine online again if there is some work pending to be completed. One should keep the functions of system object storage active by making the machine online. Missing files are updated as soon as the activation is done again for the online replication instantly.
- When the failure happens, it can withstand it by stopping the running object services. Object services will be enabled to remain undamaged or unaffected by the crash. It means it will be able to resist the failure of the service.

What is the basis of the Azure subscription plan?
Price changes depending on the product variations. Pricing is as follow:
- Monthly bills: Bills are priced every month as you will only be paying for the product in the month-end. No matter how much or how many times you use that service, it will be charged monthly based on the limit you choose.
- Usage-Based Fee: This is also known as a consumption plan. Where you will be charged on the go and only be charged based on the amount you use it, if you did not use it, you wouldn’t be charged. You apply it a lot, and you will be charged a lot.
- Trail: In the Trail period of the service client can use the full potential of the service, just to go through the service and see if it fits the organization’s needs. Azure also provides some free credits that you can use in the Azure platform.

What is Azure Pipelines?
Azure Pipelines are a service that provides continuous integration and continuous delivery (CI/CD). One can use the Pipelines to configure, automate and build in collaboration with the Git provider. The Azure DevOps Pipelines can then deploy the code to any of the cloud services.
What is the recommended best practice in securing a YAML pipeline?
To secure YAML (Yet Another Markup Language) pipeline you should create an empty template and then incrementally apply security practices. This way the end-users can access the pipeline features through a Markup file. The YAML file also extends the template to all pipelines and implements the security practices efficiently.
What might be the potential causes that a pipeline won’t trigger?
- YAML trigger settings could be overridden in the UI console
- A PR (Pull Request) trigger is not supported in Azure Repos.
- Scheduled triggers are not set in the correct time zone. Time settings could prohibit the trigger from firing.
- Branch filters are not configured in CI and PR triggers.
- UI settings take over the YAML trigger settings.
Azure Interview Question
What are the necessary components for integrating Azure DevOps and Bitbucket?
You require Azure pipelines(GitLab CI/CD) to access the Bitbucket repositories during the build, while CI triggers run the pipelines to access the Bitbucket server.
During a code review, you discover plenty of unused variables and empty catch blocks. What steps would you take to improve the quality of the code?
Select ‘Run PM’ in a Maven build task. The Apache Maven PMD plugin enables the automatic execution of the analysis tool on the source code. This analysis generates a site report to find out unused variables and empty catch blocks.
Through which way scan you continuously introduce security validation to existing pipelines?
Continuous security validation is added at every stage of the development cycle to ensure security is maintained throughout. Here are the possible ways to do it:
- Static code analysis in the IDE before you add the code to the repository
- Git source control for ensuring that you have enabled the branch policies in the repository.
- Using tools like Visual studio code analysis and Roslyn Security Analyzers to review the code.
- Use Checkmarx scan for static application security testing.
- Use tools like White Source Software to identify any security lapses in third party packages.

What is Azure Content Delivery Network? How does it work?
Content Delivery Network(CDN) in Azure is a distributed network of servers that enables the delivery of content over the web. The CDN is a high-performance solution that successfully delivers high bandwidth content to its users. It does this by strategically placing its cached content to various physical nodes across the globe.
This is how the Azure CDN works:
- The user requests a file with a special domain name.
- DNS optimizes the request to route to the nearest and the best performing POP location.
- If there is no content in the cache, it is requested from the server and then cached. After this, the content is delivered to the user.
- Additional users can also request the content using the same URL and the content will be delivered from the cache for subsequent requests.
- This continues until the TTL for the content file hasn’t expired. This ensures rapid delivery of content.
What are the features of Azure CDN?
Dynamic site acceleration – Optimizes its servers to meet the high scaling demands of the content when users increase rapidly.
CDN caching rules – Caches the content after the first request; the CDN caching rules determine the content delivery method.
HTTPS custom domain support – Azure supports HTTPS on a CDN endpoint to ensure secure domain to the web applications.
Azure diagnostics logs – The developer team uses analytics and usage logs to troubleshoot failures.
File compression – Compress large files to reduce bandwidth costs and view content with a rapid response time.
Geo-filtering – Azure CDN delivers or blocks content depending on geographical rules which make the user’s viewing experience more customized.

How can I recover a dropped Azure SQL database?
You can use automated database backups to restore a database from Azure storage. This can be done in the following ways:
- Create a new database on the same server on which you deleted the table. Recover it to a specific time which is within the retention period.
- Create a database on the same server and recover it to the time of deletion of the database.
- On any server in the same region, create a new database. Then recover it to the most recent backup.
- On any server anywhere, create a fresh database. Recover it to the most recent backups that were replicated.
