Ques. 7): How do I deploy an AWS DataSync agent?

Answer:

You install an AWS DataSync agent on your public cloud environment, Amazon EC2, or your on-premises hypervisor. You must download the agent virtual machine image from the Amazon Console and deploy it to your local VMware ESXi, Linux Kernel-based Virtual Machine (KVM), or Microsoft Hyper-V hypervisor in order to copy data to or from an on-premises file server. When using a DataSync agent, the agent must be set up to be able to connect to your file server through NFS, SMB, to NameNodes and DataNodes in your Hadoop cluster, or to your self-managed object storage via the Amazon S3 API. Deploy the agent on your Outpost to configure transfers between your S3 buckets on Amazon Outposts and S3 buckets in AWS Regions. Use the pre-installed DataSync agent AMI to configure transfers between your AWS Snowcone device and AWS storage.

To transfer data between Amazon Storage services inside the same AWS account, an agent deployment is not necessary. You can run an Amazon EC2 instance using a DataSync agent AMI to copy data to or from a self-managed in-cloud file server or between AWS Storage services in separate AWS accounts.

Ques. 11): How are files and folders converted by AWS DataSync into or out of Amazon S3 objects?

Answer:

The relationship between a file or folder and an object is one-to-one when they are copied to Amazon S3. S3 user metadata includes timestamps for files and folders as well as POSIX permissions, such as user ID, group ID, and permissions. File Gateway is fully compatible with S3 user metadata for NFS shares, enabling on-premises file-based access to data stored in Amazon S3 using AWS DataSync.

The file metadata is recovered when DataSync copies objects that include this user metadata back to an NFS server. While copying from NFS to S3, hard links and symbolic connections are also restored.

Ques. 12): Which S3 storage types and associated Amazon S3 request and storage fees apply when utilising AWS DataSync?

Answer:

Some S3 storage classes include characteristics, such as data retrieval, minimum storage capacities, and minimum storage times, that might affect your costs. To address these issues, DataSync automates data management and offers settings to reduce data retrieval.

Amazon DataSync automatically stores small objects in S3 Standard to avoid the per-object minimum capacity charge. You can enable DataSync to only verify files that were transferred by a certain activity in order to save data retrieval costs. DataSync provides controls for overwriting and removing objects so as to avoid minimum storage duration fees.

Ques. 14): How does my Amazon FSx for Lustre file system get access to using AWS DataSync?

Answer:

The DataSync service will construct Elastic Network Interfaces (ENIs) in the same VPC and subnet where your FSx for Lustre file system is stored when you create a DataSync task to transfer to or from it. These ENIs are used by DataSync to connect to your FSx for Lustre file system using the root user and the Lustre protocol. Up to five security groups can be specified when creating a DataSync location resource for your FSx for Lustre file system in order to apply them to the ENIs and set up outbound access from the DataSync service. It is necessary to set up the security groups to permit outbound traffic on the network ports needed by FSx for Lustre.  The security groups on your FSx for Lustre file system should be configured to allow inbound access from the security groups you assigned to the DataSync location resource for your FSx for Lustre file system.

Ques. 15): How does Amazon FSx for OpenZFS file system access work with AWS DataSync?

Answer:

The DataSync service will construct Elastic Network Interfaces (ENIs) in the same VPC and subnet where your FSx for OpenZFS file system is situated when you start a DataSync task to transfer to or from it. These ENIs are used by DataSync to connect to your FSx for OpenZFS file system using the root user's OpenZFS protocol. To apply to the ENIs and set up outbound access from the DataSync service, you can select up to five security groups when you build a DataSync location resource for your FSx for OpenZFS file system. It is necessary to set up the security groups to permit outbound traffic on the network ports needed by FSx for OpenZFS. The security groups on your FSx for OpenZFS file system should be configured to allow inbound access from the security groups you assigned to the DataSync location resource for your FSx for OpenZFS file system.

Ques. 16): How does Amazon FSx for Netapp ONTAP access my file system?

Answer:

When you create a task, DataSync creates Elastic Network Interfaces (ENIs) in your Amazon FSx for NetApp ONTAP file system's Preferred Subnet of the same VPC. DataSync uses the ENIs it creates in the Preferred Subnet, which is selected when you construct your FSx for ONTAP file system, to access your FSx for ONTAP file system. To configure outbound access from the DataSync service, you can specify up to 5 security groups to apply to the ENIs when you create a DataSync Location resource for your FSx for ONTAP file system. You should configure the security groups on your FSx for ONTAP file system to allow inbound access from the security groups you assigned to the DataSync Location resource for your FSx for ONTAP file system.

Set up your online data move job between AWS Snowcone's NFS store and Amazon S3, Amazon EFS, Amazon FSx for Windows File Server, Amazon FSx for Lustre, Amazon FSx for OpenZFS, or Amazon FSx for NetApp ONTAP after activating the agent using the AWS Management Console or CLI.

 

Amazon EMR Interview Questions and Answers

Amazon OpenSearch Interview Questions and Answers

AWS EC2 Auto Scaling Interview Questions and Answers

 

Ques. 19): Would the performance of my source file system be impacted by AWS DataSync?

Answer:

Because the agent reads or writes data from that storage system, Amazon DataSync may affect the response time of other clients when accessing the same source data store, depending on the capacity of your on-premises file store and the amount and size of files to be transferred. This effect can be lessened by configuring a bandwidth restriction for a process, which limits the I/O to your storage system.

AWS Lightsail Questions and Answers

 

 

Top 20 AWS Lightsail Questions and Answers

 

 

For developers, small enterprises, students, and other customers that want a solution to create and run their applications in the cloud, Amazon Lightsail is a virtual private server (VPS) provider and the simplest method to get started with AWS. Developers may install and manage websites and web applications in the cloud using Lightsail's computing, storage, and networking capability. For a cheap, dependable monthly cost, Lightsail offers everything you need to swiftly begin your project, such as virtual machines, containers, databases, CDN, load balancers, DNS management, etc.

 

AWS(Amazon Web Services) Interview Questions and Answers

AWS Cloud Interview Questions and Answers

 

Ques. 1): How effective are Lightsail instances?

Answer:

AWS particularly designed Lightsail instances for usage with web servers, developer environments, and tiny databases. Such tasks occasionally require a performance burst but do not frequently or routinely demand the entire CPU. Burstable performance instances, which Lightsail employs, offer a basic amount of CPU performance with the option to burst over it. This approach protects you from the inconsistent performance or other frequent negative effects that you may normally see from over-subscription in other situations while enabling you to obtain the performance you need, when you need it.

Use Amazon EC2 if you want highly customizable settings and instances with consistently good CPU performance for applications like video transcoding or HPC workloads.

 

AWS AppSync Interview Questions and Answers

AWS Cloud9 Interview Questions and Answers

 

Ques. 2): How do DNS records work?

Answer:

DNS is a widely used service that converts domain names like www.example.com into the numerical IP addresses used by computers to communicate to one another, such as 192.0.2.1. You may quickly link the public IPs of your Lightsail instances to your registered domain names, such as photos.example.com. In this way, Lightsail automatically converts human readable names like example.com that people put into their browsers into the IP of the instance you wish to send them to. These translations are all referred to as DNS queries.

It's crucial to understand that you must register a domain in Lightsail before using it. You can register new domains using Amazon Route 53, or your preferred DNS registrar.

AWS RedShift Interview Questions and Answers

 

Ques. 3): What can I do in Lightsail using tags?

Answer:

With tags, you can categorise and filter your resources in the Lightsail interface and API, keep track of and arrange your charges in your bill, and set access management rules to control who may see or alter your resources. With the use of tags, you can:

Organize - View and manage resources based on the tags you've given them using the Lightsail interface and API filters. This is helpful if you have a lot of resources of the same type since you can easily recognise a particular resource based on the tags you've given it.

Cost-allocate - By identifying your resources and setting "cost allocation tags" in the billing interface, you may track and distribute expenses across various projects or users. You may, for instance, break out your bill and analyse your expenditures by client or project.

Using AWS Identity and Access Management rules, you can manage access and limit who may create, update, and remove Lightsail resources. You can work more effectively with people on projects without having to grant them complete access to your Lightsail resources thanks to this.


AWS Cloud Practitioner Essentials Questions and Answers

AWS EC2 Interview Questions and Answers

 

Ques. 4): A Lightsail instance is what?

Answer:

A Lightsail instance is an AWS Cloud-based virtual private server (VPS). Utilize your Lightsail instances to run code, store data, and create webpages or web apps. Both public (Internet) and private (VPC) networking options are available for your instances to use when connecting to one another and to other AWS services. From the Lightsail console, you can simply create, manage, and connect to instances.


AWS Lambda Interview Questions and Answers

AWS Cloud Security Interview Questions and Answers

 

Ques. 5): What are photographs?

Answer:

Point-in-time backups of instances, databases, or block storage devices are known as snapshots. You may take a snapshot of your resources at any moment, or you can instruct Lightsail to take snapshots for you by turning on automatic snapshots for instances and discs. Snapshots can be used as starting points for building new resources or when backing up data. All the information required to recover your resource is in a snapshot (from the moment when the snapshot was taken). The rebuilt resource starts out as an identical clone of the old resource that was used to construct the snapshot when you restore a resource by building it from a snapshot.

You can manually take snapshots of your Lightsail instances, disks, and databases, or you can use automatic snapshots to instruct Lightsail to take daily snapshots of your instances and disks automatically.

Ques. 7): A Lightsail instance plan: what is it?

Answer:

A Lightsail package, also known as a bundle, contains an SSD-based virtual private server, SSD-based storage, and a data transfer allowance. The virtual private server has a defined quantity of RAM and vCPUs. Additionally, the Lightsail plans provide DNS control and five static IP addresses per account (3 domain zones per account). Plans with Lightsail are only paid for when you use them because they are hourly, on-demand fees.


AWS Cloudwatch interview Questions and Answers

AWS Elastic Block Store (EBS) Interview Questions and Answers

 

Ques. 8): What are the maintained databases at Lightsail?

Answer:

The managed databases offered by Lightsail are instances that are solely used to operate databases rather than other workloads like web servers, mail servers, etc. The same tools and programmes you use to access a stand-alone database may also be used to access a Lightsail database, which can contain many user-created databases. Lightsail keeps your database's operating system and underlying infrastructure safe and secure so that you may administer a database without having a strong background in infrastructure management. Lightsail databases have a defined amount of memory, processing power, and SSD-based storage that you can scale up over time, much like standard Lightsail instances. Your selected database will be installed and configured for you by Lightsail immediately after it is created.


AWS Amplify Interview Questions and Answers

AWS Secrets Manager Interview Questions and Answers

 

Ques. 9): What can I do with the block storage in Lightsail?

Answer:

Similar to an individual hard drive, Lightsail block storage offers extra storage volumes (referred to as "connected discs" in Lightsail) that you may attach to your Lightsail instance. Applications and software that need to split off specialised data from their core services can benefit from attached discs. They can also be used to preserve application data in the event that your instance and system disc experience a failure or other problem. Applications or software that often access their stored data might benefit from the constant performance and reduced latency provided by attached drives.

Solid-state discs are used in Lightsail block storage (SSD). This kind of block storage aims to handle the great majority of Lightsail workloads by balancing affordability and performance. Adopt EC2 with GP2 or Provisioned IOPS SSD storage in place of Lightsail for clients whose applications need consistent IOPS performance, high throughput per disc, or are running sizable databases like MongoDB, Cassandra, etc.

Ques. 10): What distinguishes halting from deleting my instance?

Answer:

Your instance is shut down when you stop it, but it is still switched on and ready for you to restart it whenever you choose. It is advised to use static IPs for instances that must maintain the same IP after they cease since stopping your instance would relinquish its public IP.

Your instance will be deleted, which is a detrimental operation. Your instance data will all be lost and unrecoverable unless you have taken an instance snapshot. Both the instance's public and private IP addresses will be made public. If you were utilising a static IP with that instance, it stays in your account but is detachable.

AWS Glue Interview Questions and Answers


Ques. 11):  What aspects of my managed database does Lightsail handle for me?

Answer:

Your database's core architecture and a variety of maintenance tasks are managed by Lightsail. To assist prevent data loss or component failure, Lightsail automatically backs up your database and offers point-in-time recovery using the database restore tool for the last seven days. Additionally, Lightsail automatically encrypts your data while it is in transit and at rest for improved protection. It also saves your database password for quick and safe database connections. On the maintenance front, Lightsail performs database maintenance within the designated maintenance time. The administration of the operating system and underlying infrastructure, as well as automated updates to the most recent minor database version, are all included in this maintenance.

Ques. 12):  In Lightsail, how do I utilise IPs?

Answer:

An automated private IP address and a public IP address are assigned to each Lightsail instance. The private IP can be used to send data secretly and without cost between Lightsail instances and AWS services. You may connect to your instance from the Internet using the public IP, for example, by using a registered domain name or an SSH or RDP connection from a local computer. The public IP may be replaced with a static IP address by adding a static IP to the instance, which will remain the same even if you stop and restart the instance.

Ques. 19):  What kind of usage does Lightsail CDN encourage?

Answer:

Amazon To make the cost of utilising the service straightforward and predictable, Lightsail CDN distributions are built using fixed-priced bundles of data transport. A month's worth of consumption is covered by a distribution package. Distribution bundles may not be used for purposes other than those for which they were designed, such as repeatedly upgrading or downgrading bundles or employing an abnormally high volume of distributions from a single origin. Workloads that need a lot of requests per second or a lot of streaming video are also not allowed. Your data services or account may be throttled or suspended if you engage in these actions.

Ques. 20):  What's the difference between removing my container service and halting it?

Answer:

Your container nodes are in a disabled state when you disable your container service, and the public endpoint of the service returns an HTTP status code of '503'. The service returns to the most recent active deployment when it is enabled. Configurations for power and scalability are also kept. Following re-enabling, the public endpoint's name remains unchanged. Container images and deployment history are kept.

You are acting destructively when you remove your container service. All of the service's container nodes will be permanently destroyed. Additionally, your service's container images, deployment history, logs, and HTTPS public endpoint address will all be permanently erased. It is impossible for you to get the endpoint address back.
