Top 20 AWS Migration Evaluator Interview Questions and Answers

 


Ques. 1): What is supported by Migration Evaluator? What is not supported by Migration Evaluator?

Answer:

The x86 architecture of the server and the associated block storage of the customer are supported by Migration Evaluator. Based on the provisioning, software licencing, and use, the software discovers Amazon EC2 matches. Since it was not created to monitor or report on storage appliances, mainframes, or network devices like routers, Migration Evaluator currently does not allow modelling of Solaris, AIX, or other non-x86 systems.

Top 20 AWS SES Interview Questions and Answers

 

 

Ques. 1):  Support for Sender Policy Framework (SPF) is there in Amazon SES?

Answer:

Yes, SPF is supported by Amazon SES. Depending on the method you choose to deliver emails using Amazon SES, you might need to publish an SPF record. Because Amazon SES automatically distributes emails from an MAIL FROM domain that is held by Amazon Web Services, you do not need to publish an SPF record if you do not need to comply with Domain-based Message Authentication, Reporting and Conformance (DMARC) using SPF. You must configure Amazon SES to utilise your own MAIL FROM domain and publish an SPF record in order to comply with DMARC utilising SPF.

Ques. 2): Is the maximum size of an email that Amazon SES can deliver?

Answer:

Email messages up to 40MB in size, including any included graphics and attachments, are supported using the Amazon SES v2 API and SMTP. When sending messages greater than 10MB, you may experience bandwidth throttling that reduces your sending speed to as little as 40MB/s. For instance, you may send two 20MB messages per second or one 40MB message at a pace of 1 message per second.

The Amazon SES API v1 can handle messages up to 10MB in size, including any images and attachments.

Ques. 3): Can I send a certain number of emails each day?

Answer:

Sending restrictions apply to every Amazon SES account differently. These boundaries are:

The maximum number of people to whom you can send emails within a 24-hour period is known as the "sending quota."

The maximum send rate is the number of recipients you can email at once.

Sending restrictions are determined by recipients as opposed to messages. Utilizing the Amazon SES dashboard, you can check your sending restrictions whenever you want.

We reserve the right to temporarily suspend your capacity to send email if we deem that the email you send is of poor or doubtful quality (for instance, if it has a high bounce or complaint rate, contains unsolicited or malicious information, etc.).

Ques. 4): When I send specific kinds of emails, can I provide a dedicated IP address?

Answer:

You can establish groupings (pools) of the dedicated IP addresses you've leased to use with your Amazon SES account by using the dedicated IP pools feature. You can then link each pool to a configuration set, which restricts the IP addresses from which emails can be sent while using that configuration set.

Ques. 6): Can Amazon SES send emails with attachments?

Answer:

Amazon SES supports many popular content formats, including documents, images, audio, and video.

For your own safety and that of your customers, Amazon SES scans every attachment that you send for viruses and malware. You can use an email client that supports SMTP to send email with attachments. When you configure a client to send outgoing email through Amazon SES, the client constructs the appropriate MIME parts and email headers before sending the message.

You can also send email with attachments programmatically. To include an attachment in your email, construct a new multipart email message. In the message, include a MIME part that contains an appropriate Content-Type header, along with the MIME-encoded content. Next, use the Content-Disposition header to specify whether the content is to be displayed inline or treated as an attachment.

Once you've composed your message, you can use the SendRawEmail API operation to send it.

Ques. 7): How quickly do emails sent over Amazon SES get to recipients' inboxes?

Answer:

Within a few seconds of receiving a request, Amazon SES makes an effort to transmit emails to the Internet. However, we are unable to determine with precision when your email will arrive or the precise path the message will take to reach its destination due to a number of circumstances and the inherent ambiguities of the Internet.

 

For instance, a momentary issue like "mailbox full" can prevent an ISP from sending the email to the receiver. Amazon makes an effort to redeliver the message in these circumstances. Amazon SES does not retry to send the message if the issue is persistent, such as "mailbox does not exist," and you are notified of a hard bounce. You can configure delivery notifications to notify you when one of your emails is successfully delivered to a recipient's mail server.

AWS AppFlow Interview Questions and Answers

 

Ques. 8): Can I encrypt received email messages?

Answer:

AWS Key Management Service (KMS), with which Amazon SES has integrated, enables you to encrypt the mail that is written to your Amazon S3 bucket. Your email is encrypted via client-side encryption before being sent to Amazon S3 by Amazon SES. This indicates that when you retrieve the message from Amazon S3, you must decrypt the content on your end. You can get a client that can take care of the decryption with the help of the AWS Java SDK and AWS Ruby SDK.

AWS QLDB Interview Questions and Answers

 

Ques. 9): What distinguishes Amazon SES from Amazon SNS?

Answer:

Applications that require the sending of email communications should use Amazon SES. Numerous MIME types and customised email header fields are supported by Amazon SES.

While numerous subscribers can request and receive "push" notifications of time-critical messages over a selection of transport protocols, including HTTP, Amazon SQS, and email, Amazon Simple Notification Service (Amazon SNS) is for messaging-oriented applications. The body of an Amazon SNS notice isn't designed to support multimedia material and has a character limit of 8192 UTF-8 strings.

AWS STEP Functions Interview Questions and Answers

 

Ques. 10): Does Amazon SES ensure that my emails will be received?

Answer:

To assist ensure that valid, high-quality email is delivered reliably to recipients' inboxes, Amazon SES continuously checks ISP policies. However, delivery of each and every email cannot be guaranteed by Amazon SES or any other email-sending provider. The recipients of your emails may mistakenly provide the wrong email address, ISPs may opt to reject or silently drop them, and recipients may choose not to receive your emails.

Ques. 11): Does using Amazon SES require me to sign up for Amazon EC2 or any other AWS services?

Answer:

Users of Amazon SES do not need to register for any additional AWS services. Whether an application is running in your own data centre, within Amazon EC2, or as a client software solution, as long as it has Internet connection, it can send email using Amazon SES.

Ques. 12): How can Amazon SES be tested quickly and easily?

Answer:

New users can test out Amazon SES's features in the sandbox for the service. You can only email confirmed identities when your account is in the sandbox. An email address or domain that you have demonstrated to be yours is a verified identity.

Additionally, there are restrictions on how much email you can send each day and how many messages you can send each second when your account is in the sandbox.

AWS Serverless Application Model(SAM) Interview Questions and Answers

 

Ques. 13): Can I use any email address to send emails?

Answer:

No. Only email addresses and domains that you own may be used to send emails using Amazon SES.

You must validate an email address or domain to show that you are the owner. You can validate up to 10,000 email addresses and domains in any combination in each AWS Region.

Ques. 14): What distinguishes a dedicated IP address from a managed IP address?

Answer:

You can manage your sending reputation using both Dedicated IP choices by using reserved IP addresses. You must manually set up and manage your IP addresses if you use Dedicated IP Addresses (standard). Managed dedicated IP addresses eliminate the requirement for manual dedicated IP pool scaling or monitoring. Additionally, it enables you to more correctly predict the warmup condition and avoid oversending, which can harm deliverability.

Ques. 15): Is it possible to test Amazon SES answers without using real recipients' email addresses?

Answer:

Without sending emails to actual recipients, you can use the Amazon SES mailbox simulator to assess your sending speed and your capacity to handle situations like bounces and complaints. Your daily sending quota, bounce and complaint metrics, and complaints received metrics are not affected by messages you send to the mailbox simulator. We do, however, charge you for each message you send to the mailbox simulator, just as we would if you were sending the messages to real clients.

Ques. 16): How does Amazon SES make sure that the mail that arrives is free of viruses and spam?

Answer:

A variety of spam and virus prevention techniques are used by Amazon SES. Block lists are used to stop mail from known spammers from ever entering the system. Every incoming email that has an attachment is additionally virus-scanned. You can choose whether to trust each message by consulting Amazon SES's spam detection results. Amazon SES also delivers the results of the DKIM and SPF checks in addition to the spam and virus evaluations.

Ques. 17): Can bounces or complaints from other Amazon SES users influence the delivery of my emails?

Answer:

Typically, your ability to send email is unaffected when other Amazon SES users send messages that result in bounces or complaints.

When a recipient's email address causes a hard bounce, this rule is disregarded. Amazon SES puts a recipient's email address on a worldwide suppression list when it receives a hard bounce. The call to Amazon SES succeeds if you attempt to send an email to an address that is on the global suppression list, but Amazon SES handles the email as a hard bounce rather than making an attempt to send it.

Emails that you send to addresses on the global suppression list count toward your sending quota and your bounce rate. An email address can remain on the suppression list for up to 14 days.

Ques. 18): Is Domain Keys Identified Mail (DKIM) supported by Amazon SES?

Answer:

Yes, DKIM is supported by Amazon SES. If Easy DKIM has been enabled and setup, Amazon SES will use DKIM to sign your outgoing messages. You can manually sign your email if you'd like. There are a few DKIM headers that you shouldn't sign in order to guarantee optimum deliverability.

Ques. 19): In what ways does Amazon SES contribute to dependable email delivery?

Answer:

Outgoing email messages are screened using content screening algorithms by Amazon SES. These content filters aid in ensuring that the content supplied over Amazon SES adheres to ISP standards. Amazon SES offers a feedback loop with delivery, bounce, and complaint notifications to assist you in further enhancing the deliverability of your emails.

 

AWS FinSpace Interview Questions and Answers

AWS MSK Interview Questions and Answers

AWS ECR Interview Questions and Answers

 

Ques. 20): Does Amazon SES use Transport Layer Security (TLS) to encrypt connections when sending email?

Answer:

For TLS connections, Amazon SES supports TLS 1.2, TLS 1.1, and TLS 1.0.

Amazon SES utilises opportunistic TLS by default. This indicates that Amazon SES makes an effort to connect securely to the receiving mail server at all times. Amazon SES transmits the communication unencrypted if it is unable to establish a secure connection.

You can alter this behaviour so that Amazon SES transmits emails to the recipient email server only when a secure connection can be made.

Top 20 AWS RDS Interview Questions and Answers


A managed service called Amazon Relational Database Service (Amazon RDS) makes it simple to set up, run, and scale a relational database in the cloud. While managing time-consuming database administration activities, it offers cost-effective and scalable capacity, freeing you to concentrate on your applications and company.

You have access to the features of a well-known MySQL, MariaDB, Oracle, SQL Server, or PostgreSQL database using Amazon RDS. This indicates that Amazon RDS should function seamlessly with the code, apps, and tools you now use with your existing databases. Your database can be automatically backed up via Amazon RDS, and the most recent version of your database software can always be used. You gain from the adaptability that comes with being able to quickly scale the computing or storage resources connected to your relational database instance. Additionally, for read-intensive database workloads, Amazon RDS makes it simple to implement replication to increase database availability, improve data durability, or extend beyond the limitations of a single database instance. There are no upfront costs involved, and you just pay for the resources you use, like with all Amazon Web Services.

 

AWS(Amazon Web Services) Interview Questions and Answers

AWS Cloud Interview Questions and Answers

 

Ques. 1): What should I do if my queries appear to be taking a while to execute?

Answer:

We recommend turning up Enhanced Monitoring for production databases, which gives you access to more than 50 CPU, RAM, file system, and disc I/O metrics. You can select the granularity and enable these functionalities on an instance-by-instance basis (all the way down to 1 second). The performance of queries can be negatively impacted by high CPU utilisation, so you might choose to scale your DB instance class in this situation.

If your database uses RDS for MySQL or MariaDB, you can examine the slow query logs to find out whether any SQL queries are performing slowly and, if so, what their individual performance traits are. To review the slow-moving SQL queries, you could set the "slow query log" DB Parameter and query the mysql.slow log table. You can spot slow queries if you're using RDS for Oracle by looking at the information in the Oracle trace file. If you're using RDS for SQL Server, you can find slow queries using the client side SQL Server traces.

Ques. 2): How can you can examine the slow query logs to find out whether any SQL queries are performing slowly?

Answer:

To review the slow-moving SQL queries, you could set the "slow query log" DB Parameter and query the mysql.slow log table. You can spot slow queries if you're using RDS for Oracle by looking at the information in the Oracle trace file. If you're using RDS for SQL Server, you can find slow queries using the client side SQL Server traces.

Using the AWS Management Console, Amazon RDS APIs, or AWS Command Line Interface, creating DB instances is straightforward. Using the AWS Management Console, click "RDS" and then the "Launch DB Instance" button on the Instances tab to start a database instance. The parameters for your database instance can then be specified, including the database engine and version, licence model, instance type, storage type and quantity, and principal user credentials.

Ques. 3): When would I utilise Relational Database AMIs for Amazon EC2 instead of Amazon RDS?

Answer:

For developers, Amazon Web Services offers a variety of database substitutes. By offloading database administration, Amazon RDS enables you to run a fully managed and feature-rich relational database. You may control your own relational database in the cloud by utilising one of our many relational database AMIs on Amazon EC2. These alternatives have significant differences that could make one more suitable for your use case.

Ques. 5): Can I test a new version of my database before upgrading?

Answer:

Yes. To achieve this, you can take a database snapshot of your current database instance, restore the database instance using the database snapshot, then start a version upgrade for the newly created database instance. Before determining whether or not to upgrade your original DB instance, you can experiment securely on the upgraded duplicate of your DB instance.

Ques. 7): What if I want to cover an existing database instance with a reserved instance?

Answer:

Simply acquire a DB instance reservation in the same Region as the DB instance you are presently running and want to reserve, with the same DB instance class, DB engine, Multi-AZ option, and License Model. If the reservation purchase is successful, Amazon RDS will immediately charge your existing DB instance with the new hourly usage fee.

Ques. 8): Are Multi-AZ deployments able to use reserved instances?

Answer:

Yes. When purchasing a reserved instance, you can choose the Multi-AZ option from the list of potential DB instance configurations. Additionally, a Multi-AZ reserved instance will cover usage for two Single-AZ DB instances if you are using a DB engine and licence model that enable flexible reserved instance sizes.

AWS Secrets Manager Interview Questions and Answers

 

Ques. 9): Will my database instance be accessible after scaling?

Answer:

You can increase the storage space allotted to your DB Instance while still keeping it available. However, your database will be briefly inaccessible when the DB instance class is changed if you want to scale the compute resources that are available to your DB instance up or down. Unless you specify that the adjustment should be done immediately, this brief period of unavailability usually only lasts a few minutes and occurs during the maintenance window for your DB Instance.

 

AWS Django Interview Questions and Answers

AWS Cloud Support Engineer Interview Question and Answers

 

Ques. 10): Does my DB Instance automatically do backups, or do I need to turn them on?

Answer:

Your DB Instance can automatically be backed up with a 7-day retention period via Amazon RDS by default. Only active DB Instances are eligible for the free backup storage, which is capped at the size of your supplied database. For instance, we will give you 100 GB-months of backup storage for free if you have 100 GB of allocated database storage every month.

When creating a new DB Instance, you can use the console, the CreateDBInstance API, or the ModifyDBInstance API to change the backup retention duration (for existing instances). You can use these APIs to change the RetentionPeriod parameter to any number from 0 (which will disable automated backups) to the desired number of days. The value can't be set to 0 if the DB instance is a source to Read Replicas.

Ques. 11): How does Amazon RDS function with Amazon Virtual Private Cloud (VPC)?

Answer:

Establish a virtual networking environment with total control over elements including private IP address ranges, subnets, routing tables, and network gateways using Amazon VPC to create a private, isolated area of the AWS cloud. By defining a virtual network topology and customising the network configuration with Amazon VPC, you may make your virtual network closely match an IP network that you might run in your own data centre.

When you want to preserve non-publicly accessible backend servers on a private subnet while still running a public-facing web service, VPC can be useful. You can create a public-facing subnet for your webservers that has access to the Internet, and place your backend Amazon RDS DB Instances in a private-facing subnet with no Internet access.


AWS Cloud Interview Questions and Answers

AWS VPC Interview Questions and Answers         

 

Ques. 12): What security measures should I do to guarantee that my application may access my DB Instances in VPC?

Answer:

To make sure that your DB instance can be reached from your client instances in the VPC, it is your responsibility to adjust the routing tables and networking ACLs in the VPC. Your client's EC2 instance and Amazon RDS DB Instance may be in separate Availability Zones for Multi-AZ setups after failover. You should set up your networking ACLs to permit communication across AZs.

AWS Aurora Interview Questions and Answers

 

Ques. 13): What is the difference between an AWS account and an Amazon RDS primary user account?

Answer:

You must have a developer account with AWS in order to use Amazon RDS. You will be asked to create one when you start the Amazon RDS sign-up process if you don't already have one. A primary user account is utilised exclusively in the context of Amazon RDS to manage access to your DB Instance and is distinct from an AWS developer account (s). Your DB Instance can be accessed via the principal user account, which is a native database user account.

Each DB Instance can have a primary user name and password specified when the DB Instance is created. Once you have created your DB Instance, you can connect to the database using the primary user credentials. Subsequently, you may also want to create additional user accounts so that you can restrict who can access your DB Instance.


AWS Database Interview Questions and Answers

AWS ActiveMQ Interview Questions and Answers

 

Ques. 14): On my Amazon RDS databases, can I encrypt data in transit?

Answer:

For all database engines supported by Amazon RDS, encryption at rest is supported using keys managed by AWS Key Management Service (KMS). A database instance running with Amazon RDS encryption encrypts all automated backups, read replicas, snapshots, and data stored at rest in the underlying storage. The handling of encryption and decryption is transparent.

By producing a DB snapshot, a copy of that snapshot, and a KMS encryption key, you may also add encryption to a previously unencrypted DB instance or DB cluster. After that, you can use the encrypted snapshot to restore an encrypted database instance or database cluster. Amazon RDS for Oracle and SQL Server support those engines' Transparent Data Encryption (TDE) technologies.


AWS CloudFormation Interview Questions and Answers

AWS GuardDuty Questions and Answers

 

Ques. 15): How do I pick the appropriate setup settings for my DB Instance(s)?

Answer:

By default, Amazon RDS selects the best configuration settings for your DB Instance while taking the instance class and storage capacity into consideration. The Amazon RDS APIs, the AWS Command Line Interface, or the AWS Management Console can all be used to modify them, though. Please be aware that altering configuration parameters from recommended values can result in unanticipated consequences such as performance degradation or system failures and should only be done by experienced users who are willing to take these risks.

 

AWS Control Tower Interview Questions and Answers

AWS Lake Formation Interview Questions and Answers

 

Ques. 16): Will I be informed if there is an automated failover?

Answer:

Yes, to let you know that an automatic failover took place, Amazon RDS will broadcast a DB instance event. To retrieve details about events pertaining to your DB instance, utilise the DescribeEvents API or the "Events" component of the Amazon RDS Console. To receive notifications when particular DB events happen, you may also use Amazon RDS Event Notifications.

 

AWS Data Pipeline Interview Questions and Answers

Amazon CloudSearch Interview Questions and Answers 

 

Ques. 17): How does running a database instance as a read replica work?

Answer:

For read-intensive database workloads, read replicas make it simple to utilise supported engines' built-in replication functionality to elastically expand out beyond the capacity restrictions of a single DB instance.

With just a few clicks in the AWS Management Console using the CreateDBInstanceReadReplica API, you may build a read replica. Database updates on the source DB instance will be duplicated using a supported engine's native, asynchronous replication once the read replica has been built. For a specific source DB Instance, you can build multiple read replicas and divide the read traffic from your application across them.

Read replicas are susceptible to the advantages and disadvantages of the built-in replication of supported engines. The replication lag might vary greatly, and in particular, updates are applied to your read replica(s) after they happen on the source DB instance. Along with the improved database write availability and data durability that Multi-AZ deployments offer, read replicas can be used with Multi-AZ deployments to benefit from read scaling.

Ques. 18): How can I establish a connection to my read replica?

Answer:

By retrieving the endpoint(s) for your read replica using the DescribeDBInstance API or the AWS Management Console, you can connect to a read replica in the same way that you would connect to a conventional DB instance (s). Your application will decide how read traffic will be split across your read replicas if you have more than one.

Ques. 19): Can I utilise a read replica to increase write availability in the database or to safeguard the data on my source DB instance against failure scenarios?

Answer:

We advise running your DB instance as a Multi-AZ deployment if you want to employ replication to boost database write availability and safeguard recent database modifications against various failure scenarios. Database writes occur on a read replica with Amazon RDS Read Replicas, which leverage supported engines' native, asynchronous replication, after they have already occurred on the source DB instance. This replication "lag" might vary greatly.

In contrast, Multi-AZ installations use synchronous replication, which allows all database writes to occur simultaneously on the primary and standby. This safeguards your most recent database updates, which need to be accessible on the standby in the event that a failover is necessary.

Replication is fully controlled with Multi-AZ setups as well. In the event of an outage, Amazon RDS immediately initiates a failover to the standby (or to a read replica, in the case of Amazon Aurora) and monitors for DB instance failure conditions or Availability Zone failure.

Ques. 20): Can I only perform database read operations on my read replicas?

Answer:

Read traffic is intended to be served by read replicas. Advanced users could, however, want to execute Data Definition Language (DDL) SQL operations against a read replica in some use situations. Adding a database index to a read replica that is used for business reporting without adding the same index to the relevant source DB instance is one example.

You may set up Amazon RDS for MySQL to allow DDL SQL statements against a read replica. Change the active DB parameter group for the read replica by changing the "read only" parameter to "0" if you want to enable operations other than reads for a specific read replica.
