Which AWS services or features provide disaster recovery solutions for Amazon EC2 instances? (Select TWO.)

AEC2 Reserved Instances

BEC2 Amazon Machine Images (AMIs)

CAmazon Elastic Block Store (Amazon EBS) snapshots

DAWS Shield

EAmazon GuardDuty

Suggested Answer: B, C

The correct answer isBandC. EC2 Amazon Machine Images (AMIs) and Amazon Elastic Block Store (Amazon EBS) snapshots are two AWS services that provide disaster recovery solutions for Amazon EC2 instances.

EC2 AMIsare preconfigured templates that contain the software configuration and data required to launch an EC2 instance. You can create AMIs from your running EC2 instances and use them to launch new instances in the same or different AWS Regions.This way, you can quickly recover your EC2 instances in case of a disaster that affects your primary Region or Availability Zone1.

Amazon EBS snapshotsare incremental backups of your Amazon EBS volumes. You can create snapshots of your volumes and store them in Amazon S3, which is a highly durable and scalable storage service. You can use snapshots to restore your volumes to a previous point in time or to create new volumes from snapshots.Snapshots can also be copied across AWS Regions, enabling you to recover your data in another Region in case of a disaster2.

The other options are not directly related to disaster recovery for EC2 instances:

EC2 Reserved Instancesare a pricing model that allows you to reserve EC2 capacity for a specific period of time and receive a discount on the hourly charge.Reserved Instances do not provide any disaster recovery benefits, as they are only a billing option3.

AWS Shieldis a managed service that protects your AWS resources from distributed denial-of-service (DDoS) attacks. AWS Shield provides basic protection for all AWS customers at no additional charge, and advanced protection for customers who need higher levels of detection and mitigation.AWS Shield does not provide any disaster recovery benefits, as it is only a security service4.

Amazon GuardDutyis a threat detection service that monitors your AWS account and workloads for malicious or unauthorized activity. Amazon GuardDuty analyzes various data sources, such as AWS CloudTrail, Amazon VPC Flow Logs, and DNS logs, to identify potential threats and alert you via Amazon CloudWatch Events or AWS Lambda.Amazon GuardDuty does not provide any disaster recovery benefits, as it is only a monitoring service5.

AWS Shield is not for disaster recovery, just saying!

Rodney 10 months ago

Totally agree, AMIs are super useful too!

Haydee 11 months ago

EBS snapshots and AMIs are the way to go for EC2 recovery!

Ernest 11 months ago

Wait, are you sure about AMIs? I thought they were more for backups.

Estrella 11 months ago

EBS snapshots are definitely a solid choice for DR.

Tiffiny 11 months ago

I practiced a similar question, and I think EBS snapshots and AMIs were the correct choices for backing up EC2 instances.

Cordelia 11 months ago

I feel like AWS Shield and GuardDuty are more about security than disaster recovery. They don't seem to fit this question.

Zona 12 months ago

I'm not entirely sure, but I remember something about EBS snapshots being crucial for disaster recovery. They save the state of volumes, right?

Sol 12 months ago

I think Amazon Machine Images (AMIs) might be one of the answers since they can help with recovery by creating backups of instances.

Mee 12 months ago

AWS Shield and Amazon GuardDuty are security services, not disaster recovery, so those are definitely not the right answers here.

Thurman 1 year ago

I'm a bit unsure about this one. I know EC2 Reserved Instances are for cost optimization, but I'm not sure if they're considered a disaster recovery solution.

Herman 1 year ago

Okay, I've got this. AMIs and EBS snapshots are definitely the way to go for disaster recovery on EC2.

Larae 1 year ago

Hmm, this looks like a tricky one. I'll need to think carefully about the disaster recovery features for EC2 instances.

Katy 1 year ago

I'm a bit confused by the options. What's the difference between Developer and Developer Pro? I'll need to review the details of each testing environment before making a decision.

Matilda 1 year ago

I'm a bit confused by the wording of the question. Does "little to no downtime" mean the system should be able to continue operating with no interruption, or just that the downtime should be minimized? I'll need to think through the implications of each option more carefully.

Kati 1 year ago

I remember something about the necessity of an Application Server, but I think there were exceptions in some cases.

Miesha 1 year ago

I remember prospective means looking forward, so this is about monitoring drug use before or during treatment.

Kattie 2 years ago

I believe the other correct answer is B) EC2 Amazon Machine Images (AMIs). They can be used for disaster recovery as well.

Shaun 2 years ago

I'm not sure about the other option though. Anyone know the second correct answer?

Gracia 2 years ago

I agree with Stephen, EBS snapshots are definitely part of disaster recovery solutions.

Stephen 2 years ago

I think the answer is C) Amazon Elastic Block Store (Amazon EBS) snapshots.

Shaquana 2 years ago

I believe the other correct answer is B) EC2 Amazon Machine Images (AMIs). You can create backups of your EC2 instances with AMIs.

Curt 2 years ago

I don't think AWS Shield is specifically for disaster recovery. It's more for DDoS protection.

Curtis 2 years ago

I'm not sure about the other option. What do you think about D) AWS Shield?

Pansy 2 years ago

I agree with EBS snapshots can be used for disaster recovery.

Curt 2 years ago

I think the answer is C) Amazon Elastic Block Store (Amazon EBS) snapshots.

Lanie 3 years ago

Hmm, I'm not so sure about Shield. Isn't that more for protecting against DDoS attacks? Doesn't really seem like a disaster recovery solution to me. But I could be wrong.

Denise 3 years ago

Hah, good point. Those are about as useful as a chocolate teapot in a disaster scenario. I'd steer clear of those.

Shawnee 3 years ago

Yeah, I agree with Viola. AMIs and EBS snapshots allow us to create backups of our instances and data, which we can then use to quickly spin up new instances if needed. Those are definitely the way to go for disaster recovery.

Milly 2 years ago

↳ replying to Shawnee

Yeah, I agree. And I believe it's also C) Amazon Elastic Block Store (Amazon EBS) snapshots

Toshia 2 years ago

↳ replying to Shawnee

I think it's B) EC2 Amazon Machine Images (AMIs)

Rebeca 3 years ago

What about the other options? I'm not sure I'd trust AWS Shield or GuardDuty to handle a full-blown disaster. Sounds more like security features.

Viola 3 years ago

I think the key here is to focus on the services or features that can help us recover our EC2 instances in the event of a disaster. AMIs and EBS snapshots seem like the most obvious choices to me.

Dorothy 3 years ago

This is a tricky one. I'm not sure if Reserved Instances or GuardDuty are really disaster recovery solutions for EC2 instances. Those seem more like cost-saving and security features.

Hector 3 years ago

Yeah, those are definitely the right answers. AMIs let you quickly spin up new instances, and EBS snapshots let you restore your data. Easy peasy.

Lashanda 3 years ago

↳ replying to Hector

Yeah, those are definitely the right answers. AMIs let you quickly spin up new instances, and EBS snapshots let you restore your data. Easy peasy.

C) Amazon Elastic Block Store (Amazon EBS) snapshots

Loren 3 years ago

↳ replying to Hector

B) EC2 Amazon Machine Images (AMIs)

Timothy 3 years ago

Hmm, let me think... I'd say EC2 AMIs and EBS snapshots are the obvious choices here. Those are the bread and butter of disaster recovery for EC2.

Ezekiel 3 years ago

I know, right? But it's important to be prepared. I'm glad they're testing this stuff - it could save our butts one day.

Janet 3 years ago

Ugh, disaster recovery questions are the worst. I hate having to think about all the bad things that could happen to my instances.
