Hi Jessie and AS,
Thank you for sharing your feedback.
Resources of the resource group can be located in different regions than its associated resource group. A resource group stores metadata about the resources in a specific region where it was created, but the actual Azure resources that it contains can be in a totally different region. When you specify a location for the resource group, you’re practically specifying where that metadata is stored.
The actual scenario is a hotspot question containing 3 items, as shown below:
– Resource groups cannot span multiple regions = No
– Resources can connect to other resources located in another resource group = Yes
– You can add or remove a resource to a resource group at any time = Yes
The word “span” basically means the coverage or the scope of something. This term is used in AWS and the documentation of other cloud service providers when describing the reach of a particular service/resource, so the word itself shouldn’t be the issue.
The first statement says: “Resource groups cannot span multiple regions”
I understand that it may seem a little ambiguous at first, but that statement doesn’t mention anything about its “resources”, which is what you’ll see in the second statement. Therefore, this one is clearly alluding to the actual resource itself. Nonetheless, I do get the confusion that this statement brings.
To avoid any issues, we have just revised this scenario to further accentuate that we are talking about the resource group itself and not its resources.

Hi Jason, Ryan and MCW,
Following up on JR’s message last Friday. Our learning portal had site maintenance back on January 9, which caused a significant latency for a couple of hours. The issue has been resolved within the day as well.
You can visit our public status page for more information.

Hi Warren,
Thank you for sharing your thoughts on our practice questions. We are very much open to constructive feedback, and I see that you’ve indicated three items here that you deem to have an ambiguous answer.
I understand that you have a total of 8 years working in AWS. On my end, I started working on AWS-related projects in 2014 (10 years ago) and took the first version of the AWS Certified Solutions Architect – Associate (SAA-C00) in 2018 and its succeeding versions thereafter (SAA-C01, SAA-C02, and SAA-C03). I’ve also taken several certification exams as well such as CCNA, ITIL, SCJP/OCJP and other exams in the past.
The exam scenarios in the AWS exam had various evolutions, so to speak, in the way they are designed, but one thing still remains, which is having to choose the best solution among several related options.
We don’t make deliberate “assumptions” per se since each scenario has related keywords and key phrases that support the provided answer. However, take note that the actual exam will not divulge the entire information in the scenario, and you will need to do a certain level of analysis and assumption in order to provide the best solution for the situation. It is quite concise and not as verbose as many first-time exam takers assume. This has been the style of AWS Certification exams since its 2nd iteration (SAA-C01) as someone who has been taking these certification tests on a regular basis.
The best way to discuss this is to share with us these 3 scenarios that you are alluding to here so our team and our readers can have a better context.
I’ll be waiting for the 3 scenarios, and let’s further discuss from there.
Cheers,

Hi Fernando,
Thank you for message.
Let me answer this particular point that you mention here:
Many questions simply hyperfocus on a specific line of a document or blog, and use that to decide a correct answer. Often times that line is further clarified later in the AWS documentation, changing it’s meaning.
I took the first iteration of the official AWS Certified Solutions Architect Professional exam (SAP-C00) last 2019, then the second one (SAP-C01) and its latest version (SAP-C02). This exam is quite difficult since its scenarios offer two or more related options that can meet the requirements, but only one is the MOST suitable in terms of operational overhead, cost, and other factors mentioned.
I’ve seen your posts in our forum, and we appreciate your raising valid concerns. One case is a missing/ambiguous term for “Amazon CloudWatch Alarms” where we only added the term “metric threshold”:
Technically for the above, you do create a custom metric name as part of your CloudWatch Alarm creation process, as showcased in my response in the thread above. Nonetheless, we acknowledge this shortcoming and have refactored the scenario to avoid ambiguity.
However, you do have one thread here where BOTH the keywords in the scenario and the official AWS documentation match IN VERBATIM. You kept insisting of using a “throughput-intensive” solution over a “throughput-oriented” storage option, even though the rationale is backed up by three or more AWS documentation, including the AWS product pages.
Please see here:
We’ll continue answering the questions you posted here, and if there are issues on our side, we’re happy to fix them; but we won’t be swayed over to your opinion when the official AWS documentation clearly supports our provided answer.

Hi Fernando,
First off, thank you for bringing this up. I personally appreciate your time in discussing your thought process for this particular scenario, and I do understand your concern, as well as your decision not to reply to this discussion anymore.
I would also like to accentuate the response of CexamR and Carlo here. Whatever the outcome of our discussion here, the rationale that is backed up by the official AWS documentation should prevail.
Let me respond to these things that you said about the “throughout-oriented” and “infrequently accessed” keywords:
There is no way someone would select Cold HDD for a solution that was described as “throughout-oriented”.
One, you could remove the “throuput-oriented” in the last line. Or if you want to keep it there, at least change the option from Cold HDD to Throughput Optimized HDD.
It’s quite clear in the official documentation that Cold HDD is the MOST suitable solution for:
https://media.tutorialsdojo.com/throughput-oriented-storage.png
“Throughput-oriented storage for data that is infrequently accessed”
Those two keywords are there in verbatim. Moreover, the requirement of “MOST cost-effective” solution reinforces the need to use “Cold HDD”, just as mentioned in the table of this official AWS documentation: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volume-types.html#vol-type-hdd
-
Throughput-oriented storage for data that is infrequently accessed
-
Scenarios where the lowest storage cost is important”
Screenshot: https://media.tutorialsdojo.com/st1-vs-sc1.png
You kept on insisting that Throughput Optimized HDD volumes (st1) is the correct answer. But you haven’t provided a strong documentation for this.
The official AWS documentation mentions that a Throughput Optimized HDD volume is ideal for frequently accessed, throughput-intensive workloads.
Consider this – Does the scenario ever mentioned that…
– The data is “frequently accessed”?
– The workload is throughput-intensive?
Take note that throughput-oriented is different from throughput-intensive. You are pushing for a solution that provides more throughput, even though it is EXPLICITLY NOT required in the scenario.
We will let the readers decide whether they will believe the official AWS documentation or your unsubstantiated opinion.

Hi Fernando-6,
Thank you for posting your question. To provide more context to our readers, let’s see the scenario once again:
A company uses Amazon WorkSpaces to improve the productivity and security of its remote workers. Hundreds of remote workers log in to the virtual desktop service using the Amazon WorkSpaces client application on a regular basis. Users have reported that they cannot log in to their virtual desktops even though they have the correct credentials.
Upon investigation, the Solutions Architect discovered that the filesystem storing the user profiles has reached its capacity, which is the reason why users cannot establish a new session in Amazon WorkSpaces. The environment is configured with a 10 TB Amazon FSx for Windows File Server file system to store the user profiles.
Which of the following options should the Solutions Architect implement to solve the issue and prevent it from happening again?
The correct answer says:
Create an Amazon CloudWatch metric to monitor the FreeStorageCapacity of the file system. Write an AWS Lambda Function to increase the capacity of the Amazon FSx for Windows File Server file system using the update-file-system command. Utilize Amazon EventBridge to invoke this Lambda function when the metric threshold is reached.
Take note that the above-mentioned “metric threshold” is directly related to CloudWatch Alarms. A CloudWatch metric is different from a mere “metric” (numerical data) since it is an entity containing a custom metric, alarm, and other components.
When you create a CloudWatch Alarm, you create a user-defined metric in the “Metric Name” field as shown in the screenshots below:
https://media.tutorialsdojo.com/test_for_fernando_1.png
You will see the “metric” you created in the CloudWatch Alarms console as seen here:
https://media.tutorialsdojo.com/test_for_fernando_2.png
The official AWS documentation says:
Increase your file system’s storage capacity when it’s running low on free storage capacity. Use the FreeStorageCapacity CloudWatch metric to monitor the amount of free storage available on the file system. You can create an Amazon CloudWatch alarm on this metric and get notified when it drops below a specific threshold.
Reference:
https://docs.aws.amazon.com/fsx/latest/WindowsGuide/managing-storage-capacity.html
Another documentation says:
You can use the following solution to dynamically increase the storage capacity of an FSx for Windows File Server file system when the amount of free storage capacity falls below a defined threshold that you specify. This AWS CloudFormation template automatically deploys all of the components that are required to define the free storage capacity threshold, the Amazon CloudWatch alarm based on this threshold, and the AWS Lambda function that increases the file system’s storage capacity.
Reference
Apparently, the correct answer is fully supported by the official documentation because:
– It uses the “FreeStorageCapacity” CloudWatch metric to monitor the amount of free storage available on the file system.
– Utilizes Amazon EventBridge to invoke the Lambda function when the metric threshold is breached, in which a “metric threshold” only exists for Amazon CloudWatch Alarms.
We acknowledge that we can further improve the correct answer by:
– Explicitly mentioned “CloudWatch Alarms” in the option
– Rephrase “Create an Amazon CloudWatch metric to monitor the FreeStorageCapacity” to avoid the ambiguity of creating a CloudWatch metric.
We have made the above changes, and will be reflected in our question bank soon.

Hi Hans,
Thank you for your message. We did see that the bulk of your AZ-104 review on our site happened from September 13 to 26. Sorry to hear that you failed your exam.
You mentioned in your review that:
There were only two questions identical to the exam, the rest were very different. Maybe Microsoft updated their catalogue of questions. I used other materials to study, such as Youtube cram sessions as well as the resources on Microsoft’s website.
When you said “There were only two questions identical to the exam”, it seems that you are expecting that our practice exams are dumps. Please take note that our reviewer does not contain any identical scenarios of the actual AZ-104 (or any Azure or AWS certification exams). We don’t provide any AZ-104 exam dumps nor advertise that we have as such.
You also mentioned that: “Microsoft updated their catalogue of questions”
Take note that based on the official Azure certification page, the new updates for the AZ-104 will happen on October 26. That means Microsoft Azure hasn’t made a major change for this certification test.
Moreover, our practice exam content covered most (if not all) of the services enumerated in the official AZ-104 study guide as shown here:
Therefore, your claim that “there were only two questions identical ” [or similar] to the actual AZ-104 isn’t entirely true as we have covered most of the topics for the exam based on checking our content and on the list of services/topics on the official AZ-104 study guide.
You also mentioned that you ” …used other materials to study, such as Youtube cram sessions as well as the resources on Microsoft’s website.”
The resources you mentioned are actually quite helpful, especially the ones from Microsoft.
We have the right to hold unfair reviews like this on our portal. Again, our reviewers are not exam dumps and should not be treated as such.

Hi Wade,
Take note that an EC2 instance can have both a private and public IP address. It is already mentioned on the first statement of the scenario that the EC2 instances are publicly accessible from the Internet which is why the EC2 instance has both a private and a public IP address.
If this is just a private EC2 instance with just a private IP address then yes, it won’t be accessible but the scenario is quite clear that the EC2 instance is a public one with both a private and public IP address.

Hi Mike,
Our sincere apologies for the delayed response to your previous forum posts. Yes, our team monitors the questions posted here, and we have answered all of your past posts today.
Please take note that your “Set 2, Question 46” is unique to everyone, so it’s better to just post a snippet of the question so we can further discuss the issue more accurately.
The built-in EC2 automatic recovery has certain restrictions that may not be suitable for certain scenarios. These limitations are the following:
– It is only supported on certain EC2 instance types
– Instances that use Elastic Fabric Adapter (EFA) are not supported
– Instance with Instance Stores for storage are not supported.
– You cannot implement customized actions when the instance experiences an outage (unlike the EventBridge-based option, where you’ll have more control)
These are the several reasons why the use of built-in instance recovery is not recommended.
Please share the snippet of the question you are referring to (your Set 2, Question 46) so we can further check and revise the item as needed.
Cheers,
Jon Bonso

Hi Warren,
Thank you for sending this question over. In relation to what you wrote earlier, we don’t just set “assumptions” for our readers. We provide relevant keywords and key phrases so the users can aptly select the most suitable answer that’s being sought after by the given scenario.
Let’s further analyze the scenario you shared:
A media company recently launched their newly created web application. Many users tried to visit the website, but they are receiving a 503 Service Unavailable Error. The system administrator tracked the EC2 instance status and saw the capacity is reaching its maximum limit and unable to process all the requests. To gain insights from the application’s data, they need to launch a real-time analytics service.
Which of the following allows you to read records in batches?
KEYWORDS / KEY PHRASES:
– launch a real-time analytics service
– read records in batches
The scenario is quite clear that there is a need to launch a real-time analytics service. A “real-time” service in AWS is almost always referring to Amazon Kinesis. This is also mentioned in the provided explanation and is well-supported by the included reference to the official AWS documentation:
https://aws.amazon.com/kinesis/data-streams/
Another keyword here is “read records in batches” which is a proper use case for AWS Lambda. This is also covered in the provided explanation, as well as the AWS docs:
“Lambda reads records from the data stream and invokes your function synchronously with an event that contains stream records. Lambda reads records in batches and invokes your function to process records from the batch. Each batch contains records from a single shard/data stream.”
https://docs.aws.amazon.com/lambda/latest/dg/with-kinesis.html#kinesis-polling-and-batching
PROVIDED EXPLANATION
Amazon Kinesis Data Streams (KDS) is a massively scalable and durable real-time data streaming service. KDS can continuously capture gigabytes of data per second from hundreds of thousands of sources. You can use an AWS Lambda function to process records in Amazon KDS. By default, Lambda invokes your function as soon as records are available in the stream. Lambda can process up to 10 batches in each shard simultaneously. If you increase the number of concurrent batches per shard, Lambda still ensures in-order processing at the partition-key level.
The first time you invoke your function, AWS Lambda creates an instance of the function and runs its handler method to process the event. When the function returns a response, it stays active and waits to process additional events. If you invoke the function again while the first event is being processed, Lambda initializes another instance, and the function processes the two events concurrently. As more events come in, Lambda routes them to available instances and creates new instances as needed. When the number of requests decreases, Lambda stops unused instances to free upscaling capacity for other functions.
Since the media company needs a real-time analytics service, you can use Kinesis Data Streams to gain insights from your data. The data collected is available in milliseconds. Use AWS Lambda to read records in batches and invoke your function to process records from the batch. If the batch that Lambda reads from the stream only has one record in it, Lambda sends only one record to the function.
Hence, the correct answer in this scenario is: Create a Kinesis Data Stream and use AWS Lambda to read records from the data stream.
The option that says: Create a Kinesis Data Firehose and use AWS Lambda to read records from the data stream is incorrect. Although Amazon Kinesis Data Firehose captures and loads data in near real-time, AWS Lambda can’t be set as its destination. You can write Lambda functions and integrate it with Kinesis Data Firehose to request additional, customized processing of the data before it is sent downstream. However, this integration is primarily used for stream processing and not the actual consumption of the data stream. You have to use a Kinesis Data Stream in this scenario.
The options that say: Create an Amazon S3 bucket to store the captured data and use Amazon Athena to analyze the data and Create an Amazon S3 bucket to store the captured data and use Amazon Redshift Spectrum to analyze the data are both incorrect. As per the scenario, the company needs a real-time analytics service that can ingest and process data. You need to use Amazon Kinesis to process the data in real-time.
Regarding this statement:
And if the system load is going to 100% the first thing you do wouldn’t be to create a data stream on incoming data.
I understand your point here since there are many ways to debug, troubleshoot, and solve 503 errors in a web application. As someone who worked in the industry for 17 years, I’ve seen several production cases where doing data analytics to your incoming requests makes sense.
For instance, a web application can be inundated by illegitimate requests by several attacks that are not blocked by its existing Web Application Firewall. New cyber attacks coming from bots, Dark Web (TOR requests), Web Crawlers, and other sources require real-time analysis in order to block the source IP address, rate limit certain endpoints, or blacklist the request’s user agent.
It’s quite important to understand that the high CPU utilization is NOT always caused by legitimate user activity or a surge of requests due to mass web promotions. These spikes can be caused by internal systems (e.g. unoptimized & CPU-intensive reporting modules) and the aforementioned external attacks. At Tutorials Dojo, our learning portal has similar real-time analytics for incoming requests, as well as analytics for user clickstream.
Thus, the provided scenario is not entirely misleading or ambiguous since the provided keywords are amply included.

Hi Rick,
We hear you load and clear. Thank you for letting us know and our sincere apologies for the poor experience.
Can you share more about the type of advertisement you see, please? We have 3 types of marketing elements:
1. Pop-up
2. Notification Bar
3. Sidebar – Triple Bundle promo
Do you see a pop-up whenever you are on the quiz itself or just on the course page when you’re reviewing your previous exam attempts? Take note that the advertisement should only show the courses that you don’t have access to.
Based on your records, you have our:
1. AWS Certified Solutions Architect – Associate Practice Tests
2. AWS Certified Solutions Architect – Associate Video Course
We implemented a fix weeks ago not to show any pop-ups on the above pages for any user. If this is not the case, please let me know so we can further investigate your account.
We want to assist you and make our portal more conducive for learning while keeping you on the loop on our upcoming system maintenance (not just on our sale events), which is why you may still see the notification bar on top. You may also see these pop-ups sparingly on the home page as well.
In the coming weeks, we will be making the following changes to the marketing elements :
– The ads will be seen by users/visitors that are NOT logged in
– Users that are logged in won’t see any ads on the course page that they have bought including in the My Courses page, as it’s always been. However, the ads will be seen on the courses that they don’t have access yet.
Looking forward on your reply.
