Top 2o AWS QLDB Interview Questions and Answers

Ques: 1). What distinguishes a ledger database from other databases?

Since data may be overwritten or deleted in traditional databases, developers utilise strategies like audit tables and audit trails to help trace the history of the data. These strategies may be effective, but they call for specialised expertise, can be challenging to scale, and place the burden of data accuracy on the application developer. Since data in Amazon QLDB is written to an append-only journal, the developer has access to the complete data history. Additionally, the information in your ledger may be trusted because it is immutable and verifiable in the journal of Amazon QLDB.

Ques: 3). How fast can I anticipate Amazon QLDB to operate?

Compared to ledgers in typical blockchain systems, Amazon QLDB can process two to three times as many transactions. Due to the decentralised nature of blockchain systems, a majority of network participants must agree that a transaction is genuine before it can be carried out. However, QLDB's centralised architecture enables its transactions to be carried out without the need for multi-party consensus.

Ques: 5). What are QLDB Streams' ordering policies and delivery guarantees?

The Amazon QLDB Streaming feature offers a delivery guarantee of at least once. A minimum of once is streamed to Amazon Kinesis for each control, block summary, and revision details record that a QLDB Stream creates from the journal. Customers will need deduplication logic on the application layer if the application requires it since duplicate records may occasionally emerge in the Kinesis stream. There are no promises regarding the sequence in which prior blocks and changes will be released in the Kinesis stream.

AWS Cloud Security Interview Questions and Answers

Ques: 6). Is Amazon Quantum Ledger Database a blockchain or distributed ledger service?

There is no blockchain or distributed ledger system called Amazon QLDB. Blockchain and distributed ledger technologies are primarily used to address the issue of multi-party, decentralised systems that cannot be owned by a single body and in which the participants may not always have complete trust in one another. The QLDB ledger database, on the other hand, was created specifically for clients who needed to keep a comprehensive and verifiable history of data changes in a programme they owned. Along with the comfort, scalability, and simplicity of a fully maintained AWS database, Amazon QLDB delivers history, immutability, and verifiability. A blockchain solution can be suitable if your application demands decentralisation and includes several unreliable parties. Amazon QLDB is an excellent choice if your application needs a full and verifiable history of all application data changes but does not involve numerous, unreliable parties.

1/ Create an Amazon Kinesis Data Stream (KDS): Customers create a KDS stream either by using Amazon Kinesis console or AWS SDK. They can also use an existing stream.

2/ Create an Amazon QLDB Stream: Customers create an Amazon QLDB Stream using Amazon QLDB console or AWS SDK. The following key aspects need to be configured for creating the stream:

Amazon QLDB Ledger name

Target KDS stream

IAM role that Amazon QLDB will assume, which has permissions to write the KDS stream

Start time, that specifies the clock time from which to start streaming

End time, that specifies the clock time to end streaming. Omitting this optional parameter implies a continuous stream.

3/ Consume the KDS Stream: Customers can write Kinesis applications using Kinesis services, such as Kinesis Data Firehose and Kinesis Data Analytics, to consume and process the stream. Customers can also use AWS Lambda to consume the Kinesis Data Stream records.

Ques: 3). What extra value can AppFlow provide given that my SaaS application already has access to public APIs?

Answer:

While developers may accomplish a variety of basic integration tasks using the public APIs from SaaS apps, AppFlow saves clients time by enabling anybody who prefers not to write code and get familiar with the API documentation of all the different SaaS services to do so. Custom connections are replaced with the fully managed API integration service known as AppFlow. To coordinate and carry out the flows, it sets up computing, storage, and networking resources. It also handles API authorization with the SaaS application, controls the lifecycle of access tokens, and manages API keys. Finally, it processes data as part of the flow.

Answer:

Your data is always secured with AppFlow, both in transit and at rest. Your AWS managed customer master key (CMK) will be used by default by AppFlow for encryption. Additionally, you have a choice of client controlled CMKs for encryption, or managed keys. Utilizing the AWS Key Management Service, create custom keys (KMS). Once configured, your unique key is immediately used for creating flows.

AWS Lambda Interview Questions and Answers

AWS Cloud Security Interview Questions and Answers

Ques: 6). Should I use AWS DataSync or AppFlow when?

Answer:

AWS DataSync is designed to transfer massive volumes of data in bulk for processing, backup, and disaster recovery between on-premises data sources and the AWS Cloud. When one-time or recurring transfers of tens or hundreds of gigabytes are commonplace, AWS DataSync is the best option. At this size, maximising network capacity and attaining high throughput are required. In contrast, SaaS apps and AWS services exchange data through the usage of AppFlow. The operational data flows that may be started by a person, an event, or a schedule are what AppFlow is made for.

Answer:

Go to the AWS Management Console and choose the Services menu, then choose AppFlow. The AppFlow home page will then be shown. The steps listed below may be used to establish and configure a Flow by an authorised IAM user:

Link the source and destination of your data. To begin, give your flow a name and select a source and destination from the list of integrated application sources.

Select your data flow trigger from the following options: on demand flows, scheduled flows, and event-based flows, which are triggered by business events like the creation of a sales opportunity or a change in a support ticket's status.

Field mapping may be configured inside AppFlow, or for data sets with a lot of fields, a csv file with bulk field mappings can be uploaded. Add data field transformations as an option, such as hiding private financial data or merging first and last names.

Add optional data filters, such as incorporating only new or chosen data fields in your flow, and validations, such as verifying that numerical fields contain numbers.

Finish - Click Create Flow to start your data flowing based on the triggers you specified. You may always go back to your dashboard to analyse and troubleshoot data flows.

Data is sent between the data source and the data target while AppFlow also executes the chosen transformations and keeps track of the processing. For automation, security, and monitoring, AppFlow connects with core AWS services including AWS PrivateLink, AWS KMS, and Amazon CloudTrail.

Top 20 AWS Simple Notification Service (SNS) Interview Questions and Answers

A web service called Amazon Simple Notification Service (Amazon SNS) makes it simple to set up, run, and transmit notifications from the cloud. It gives developers the ability to publish messages from an application and instantly distribute them to subscribers or other apps in a highly scalable, flexible, and economical manner. For developers, it is intended to make web-scale computing simpler. The "publish-subscribe" (pub-sub) communications paradigm is used by Amazon SNS, and notifications are sent to clients using a "push" technique to avoid the need for recurring checks or "polls" for new data and updates. With pay-as-you-go pricing, no maintenance or management costs, and straightforward APIs requiring no upfront effort, Amazon SNS offers developers a simple way to integrate a potent notification system with their apps.

Ques. 2): How does the Amazon SNS function?

Answer:

With Amazon SNS, getting started is quite simple. Prior to posting messages and enabling users to subscribe for alerts, developers must first build a "topic" that serves as a "access point" and identifies a certain subject or event type. When a topic is formed, the subject owner can describe its policies, such as who is allowed to publish messages or subscribe to notifications, as well as which notification protocols (such as HTTP/HTTPS, email, or SMS) will be supported. Clients that subscribe to a subject or are subscribed by the topic owner are interested in getting alerts from relevant topics. The protocol and end-point (URL, email address, etc.) where notifications should be sent are specified by subscribers. Publishers that have information or updates for their subscribers can post a message to the subject, which causes Amazon SNS to send the message to all relevant subscribers right away.

AWS Cloud Interview Questions and Answers

Ques. 3): What distinguishes Amazon SNS from Amazon MQ?

Answer:

Messaging services like Amazon MQ, Amazon SQS, and Amazon SNS are appropriate for businesses of all sizes. Consider Amazon MQ if you want to rapidly and simply migrate your messaging to the cloud while still utilising it with your current apps. You may transition from any standards-based message broker to Amazon MQ without having to completely rewrite the messaging code in your apps since it supports industry-standard APIs and protocols. We advise you to take Amazon SQS and Amazon SNS into account while developing brand-new cloud-based apps. Amazon SQS and SNS are lightweight, fully managed message queue and topic services that offer straightforward, user-friendly APIs and almost indefinite scalability. Microservices, distributed systems, and serverless applications may be scaled and decoupled using Amazon SQS and SNS, and dependability can be increased.

The relaying of time-sensitive events to mobile applications and devices is another example of how Amazon SNS is used. Developers that create applications that depend on real-time events might benefit greatly from using Amazon SNS since it is both extremely dependable and scalable.

AWS Lambda Interview Questions and Answers

AWS Cloud Security Interview Questions and Answers

Ques. 5): What are the various notice delivery formats and transports?

Answer:

SQS - Users have the option of specifying a FIFO queue or a SQS standard as the endpoint, and Amazon SNS will enqueue a notification message to the chosen queue (which subscribers can then process using SQS APIs such as ReceiveMessage, DeleteMessage, etc.).

HTTP, HTTPS - When registering for a subscription, subscribers must select a URL; alerts will be sent through an HTTP POST to the supplied URL.

Email-JSON - Messages are delivered to registered addresses by email or email-JSON. Email delivers text-based email, whereas Email-JSON sends alerts as a JSON object.

SQS – Users can choose "SQS" as the endpoint, which instructs Amazon SNS to enqueue a notification message to a SQS standard queue (which subscribers can then process using SQS APIs such as ReceiveMessage, DeleteMessage, etc.).

SMS - Text communications are transmitted as SMS to registered phone numbers.

AWS Simple Storage Service (S3) Interview Questions and Answers

AWS Fargate Interview Questions and Answers

Ques. 6): Can other AWS services be utilised with Amazon SNS?

Answer:

Other AWS services like Amazon SQS, Amazon EC2, and Amazon S3 can be combined with Amazon SNS. Here is an illustration of how a workflow system for order processing employs Amazon SNS along with Amazon EC2, SQS, and SimpleDB. In this workflow system, whenever a transaction takes place or an order moves through the order processing pipeline, messages are delivered between the application components. When a consumer puts an order, the transaction is first logged in Amazon SimpleDB before being sent to a payment processor, which deducts the customer's credit card or bank account, through an application running on Amazon EC2. An order confirmation message is then sent to an Amazon SNS topic after being authorized. The merchant, the client, and the supply chain partners are all subscribers to the subject in this scenario through Email/HTTP, and alerts provided by Amazon SNS for that topic may immediately inform them all that the payment processing was successful. An order processing system running on EC2 may also be orchestrated via notifications, where alerts provided over HTTP can start real-time processing in associated components like an inventory system or a shipping service. All sent notifications are maintained in an Amazon SQS queue through the integration of Amazon SNS and Amazon SQS, where they are later analysed by an auditing application.

AWS SageMaker Interview Questions and Answers

AWS DynamoDB Interview Questions and Answers

Ques. 7): Will a certain originating number send SMS notifications?

Answer:

Numbers will be used by Amazon SNS according to your account's settings. A dedicated short code will be used first, then one of the specialised long codes. Amazon SNS will resort to utilising a common set of numbers to send SMS notifications if you don't have dedicated numbers. While sending messages to a certain destination phone number, Amazon SNS tries to utilise the same number when utilising the shared set. Sticky Sender ID is the name for this. However, a different number could be chosen based on numerous factors including network circumstances and available throughput.

You can reserve dedicated long numbers or dedicated short codes to manage the originating identity that Amazon SNS uses to transmit messages. You may make it simpler for your audience to understand that your company is the source of your communications by reserving one or more numbers.

AWS Elastic Block Store (EBS) Interview Questions and Answers

Ques. 8): What characteristics are included in the new Worldwide SMS capability?

Answer:

With Amazon SNS, you may send SMS (text) messages to more than 200 countries without the receivers' express consent as previously. If local law or regulations prohibit you from sending SMS messages to a recipient's phone number, you must first get their consent. Additionally, you may now label your SMS messages as Transactional or Promotional to optimise for cost-savings or dependable delivery, respectively. To prevent unintentional overruns, you may also define expenditure limitations at the account and message levels.

AWS Amplify Interview Questions and Answers

AWS Secrets Manager Interview Questions and Answers

Ques. 9): How would a developer build up an Amazon SQS queue to get alerts from Amazon SNS?

Answer:

A developer should subscribe to a topic specifying "SQS" as the transport and a valid SQS standard queue as the end-point in order to have Amazon SNS transmit notifications to a SQS queue. The owner of the SQS queue must subscribe the SQS queue to the Topic in order for Amazon SNS to correctly deliver messages to the queue and enable the SQS queue to receive alerts from Amazon SNS.

Nothing further is necessary if the user already controls the Amazon SNS topic being subscribed to and the SQS queue receiving the alerts. Any message posted to the subject will be sent automatically to the designated SQS queue. Amazon SNS will seek a clear confirmation of the subscription request if the person who owns the SQS queue is not the topic's owner.

AWS Django Interview Questions and Answers

AWS Cloud Support Engineer Interview Question and Answers

Ques. 10): How many times will each message be delivered to subscribers?

Answer:

Although each message will typically only ever be delivered once to your application, the dispersed nature of Amazon SNS and fluctuating network circumstances may occasionally cause multiple messages to be received at the subscriber end. Application designers should make sure that processing a message more than once does not result in any mistakes or inconsistencies.

AWS Solution Architect Interview Questions and Answers

AWS Glue Interview Questions and Answers

Ques. 11): Describe 10DLC.

Answer:

When delivering SMS to customers in the US, you can utilise the 10-digit long code 10DLC as your originating identification. It can handle up to 100 text messages per second in throughput (TPS). The throughput that is allotted to you is not decided by AWS. Instead, when you sign up for the 10DLC, US carriers assign you throughput. Carriers demand that you supply details about your business and its use cases in order to use 10DLC numbers (also called 10DLC campaigns).

Your business and 10DLC campaigns must be registered in the Amazon Pinpoint dashboard. Once you've successfully registered and a 10DLC is active on your account, You may send SMS using Amazon SNS using this number as the originating identification. Through The Campaign Registry (TCR), a third-party central organisation that carriers utilise to verify brand identity and 10DLC campaign specifics, Amazon assists the registration procedure.

AWS Cloud Interview Questions and Answers

AWS VPC Interview Questions and Answers

Ques. 12): What are FIFO topics on SNS?

Answer:

SNS FIFO topics allow users to publish a message to a topic such that it may be sent to a number of subscribing endpoints, just as conventional SNS topics. SNS FIFO topics are the best option when the distribution of such messages to subscribers has to happen once, in order (first-in-first-out), and you want SNS to handle it. To offer consistent end-to-end message ordering for distributed applications, Amazon SNS FIFO topics send ordered messages to Amazon Simple Queue Service (Amazon SQS) FIFO queues. You may now make your communications architecture simpler and demand less work to execute your high volume, regularly ordered transactions. Example use cases include bank transaction logs, stock tickers, flight trackers, price updates, news broadcasting, and inventory management.

AWS ActiveMQ Interview Questions and Answers

Ques. 14): Can I send 10DLC messages using small URLs?

Answer:

No. The usage of short URLs offered by sites like bit.ly is not permitted by carriers. Use complete URLs that correspond to your company's domain, according to AWS. As an alternative, you may employ URL shortening providers that offer vanity or custom domains that are directly associated with the brand delivering the messages. Make sure to include these URL samples in the sample messages when registering for the 10DLC campaign.

Ques. 15): SNS Mobile Push: What Is It?

Answer:

You may use SNS Mobile Push to send push notifications to Android smartphones in China via Baidu Cloud Push, as well as to Apple, Google, Fire OS, and Windows devices. Without launching the programme, a mobile application that has been installed can instantly alert its users to an occurrence by throwing up a notice. For instance, if you download a sports app and turn on push notifications, the app will be able to provide you the most recent score of your preferred team even while it is not open. When you respond positively to the message, the app runs and displays further information.Users’ experiences are similar to receiving an SMS, but with enhanced functionality and at a fraction of the cost.

AWS Lake Formation Interview Questions and Answers

Ques. 16): How does the owner provide or remove authorization to post or subscribe to a topic?

Answer:

Developers may easily add and remove rights for a subject using the AddPermission and RemovePermission APIs. However, users should utilise access control rules to manage permissions for conditional access and more sophisticated use cases. Using the AWS Management Console is the simplest method for managing permissions.

AWS Data Pipeline Interview Questions and Answers

Amazon CloudSearch Interview Questions and Answers

Ques. 17): How does Mobile Push interact with SNS topics?

Answer:

Any supported push notification platform as well as any other endpoint type, such as SMS or email, can allow subscriptions for SNS topics. Every endpoint that has subscribed to the subject will get identical copies of any notifications you post to it. The publish will fail if it exceeds the maximum payload size set by the relevant push notifications platform if you utilise platform-specific payloads to determine the precise payload delivered to each push platform.

Ques. 19): Direct addressing is what? How does it function?

Answer:

Instead of delivering the same message to every subscriber to a topic, direct addressing enables you to send alerts directly to a particular endpoint. If you want to send each recipient exactly focused communications, this is helpful. SNS establishes a corresponding endpoint for device tokens when you register them with it. Similar to publishing to a topic, you may publish to the token endpoint. You have the option to directly publish your notification's text or a platform-specific payload that makes use of capabilities unique to that platform, such updating your app's badge count. Only endpoints that receive push notifications are presently able to use direct addressing.
