A company needs guaranteed Amazon EC2 capacity in three specific Availability Zones in a specific AWS Region for an upcoming event that will last 1 week.

A company needs guaranteed Amazon EC2 capacity in three specific Availability Zones in a specific AWS Region for an upcoming event that will last 1 week.
What should the company do to guarantee the EC2 capacity?
To guarantee Amazon EC2 capacity in three specific Availability Zones in a specific AWS Region for a 1-week event, the company should create an On-Demand Capacity Reservation that specifies the needed Region and Availability Zones. On-Demand Capacity Reservations allow you to reserve capacity for any duration and ensure that it will be available in the specified Availability Zones within the desired Region. Reserved Instances are not suitable for this case, as they require a commitment of one or three years and do not guarantee capacity specifically in specified Availability Zones.
Reserved instances are for long term so on-demand will be the right choice - Answer D
Confirmed! Reserved instances require a fixed one-year or three-year commitment. See https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html#capacity-reservations-differences
Reserved Instances – Reduce your Amazon EC2 costs by making a commitment to a consistent instance configuration, including instance type and Region, for a term of 1 or 3 years. Capacity Reservations – Reserve capacity for your EC2 instances in a specific Availability Zone.

***CORRECT*** Option D. Create an On-Demand Capacity Reservation that specifies the Region and three Availability Zones needed. An On-Demand Capacity Reservation is a type of Amazon EC2 reservation that enables you to create and manage reserved capacity on Amazon EC2. With an On-Demand Capacity Reservation, you can specify the Region and Availability Zones where you want to reserve capacity, and the number of EC2 instances you want to reserve. This allows you to guarantee capacity in specific Availability Zones in a specific Region. ***WRONG*** Option A, purchasing Reserved Instances that specify the Region needed, would not guarantee capacity in specific Availability Zones. Option B, creating an On-Demand Capacity Reservation that specifies the Region needed, would not guarantee capacity in specific Availability Zones. Option C, purchasing Reserved Instances that specify the Region and three Availability Zones needed, would not guarantee capacity in specific Availability Zones as Reserved Instances do not provide capacity reservations.
Another reason as to why Reserved Instances aren't the solution here is that you have to commit to either a 1 year or 3 year term, not 1 week.
The most appropriate option to guarantee EC2 capacity in three specific Availability Zones in the desired AWS Region for the 1-week event is to create an On-Demand Capacity Reservation that specifies the Region and three Availability Zones (option D). A. Purchasing Reserved Instances that specify the Region needed does not guarantee capacity in specific Availability Zones. B. Creating an On-Demand Capacity Reservation without specifying the Availability Zones would not guarantee capacity in the desired zones. C. Purchasing Reserved Instances that specify the Region and three Availability Zones is not necessary for a short-term event and involves longer-term commitments.
Picked C for this one and failed. Reserved Instances are reserved for 1-3 years so On-Demand Reservation makes more sense.
Check out https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html#capacity-reservations-differences Terms for Capacity Reservations: No commitment required. Can be created and canceled as needed.
Reserve instances: You will have to pay for the whole term (1 year or 3years) which is not cost effective So answer is D: on demand capacity region https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html
To guarantee EC2 capacity in specific Availability Zones, the company should create an On-Demand Capacity Reservation. On-Demand Capacity Reservations are a type of EC2 resource that allows the company to reserve capacity for On-Demand instances in a specific Availability Zone or set of Availability Zones. By creating an On-Demand Capacity Reservation that specifies the Region and three Availability Zones needed, the company can guarantee that it will have the EC2 capacity it needs for the upcoming event. The reservation will last for the duration of the event (1 week) and will ensure that the company has the capacity it needs to run its workloads.
D is the correct option to guarantee EC2 capacity in specific Availability Zones for a set timeframe. On-Demand Capacity Reservations allow you to reserve EC2 capacity across specific Availability Zones for any duration. This guarantees you will have access to those resources.
Reserved Instances have a commitment over a year so those are out. Option B only allows you to specify the Region and not the AZ. Therefore, D is the only solution.
***CORRECT*** Option D. Create an On-Demand Capacity Reservation that specifies the Region and three Availability Zones needed. An On-Demand Capacity Reservation is a type of Amazon EC2 reservation that enables you to create and manage reserved capacity on Amazon EC2. With an On-Demand Capacity Reservation, you can specify the Region and Availability Zones where you want to reserve capacity, and the number of EC2 instances you want to reserve. This allows you to guarantee capacity in specific Availability Zones in a specific Region.

Just to avoid any confusion, Reserved Instance also guarantee capacity reservation. However, the reason why we don't need Reserved Instances is because they are reserved for a duration of 1 to 3 years with a lock-in contract (no refunds!). The company is only interested in reserved capacity for a week so D is the best solution. https://aws.amazon.com/compare/the-difference-between-on-demand-instances-and-reserved-instances/
i always get these wrong
on-demand Capacity reservation for a specific AZ for gamedays
D. Create an On-Demand Capacity Reservation that specifies the Region and three Availability Zones needed
Ans D for sure
D is the correct answer
Absolutely D
D is correct
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html#capacity-reservations-differences
Yes answer is D
Answer D is correct.
Option D
D, specify the number of instances and AZs for a period of 1 week and then use them whenever needed. A and C, aren't designed to provide guaranteed capacity B, doesn't guarantee that EC2 capacity will be available in the three specific AZs
Correct answer is On-Demand Capacity Reservation: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-capacity-reservations.html
D. Reservations are used for long term. A minimum of 1 - 3 years making it cheaper. Whereas, on demand reservation is where you will always get access to CAPACITY it either be 1 week in advance or 1 month in an AZ but you pay On-Demand price meaning there is no discount.
I agree that the answer is D because its only needed for a 1 week event. C would be right if it was a re-occurring event for 1 or more years as reserved instances have to be purchased on long term commitments but would satisfy the capacity requirements. https://aws.amazon.com/ec2/pricing/reserved-instances/
Just for 1 week so D on demand
Reserved instances is for long term On-demand Capacity reservation enables you to choose specific AZ for any duration
Option D is the right answer.
its B , On-Demand Capacity Reservation allows you to reserve capacity for Amazon EC2 instances in a specific AWS Region, without specifying specific Availability Zones
Guarantee capacity on 3 AZ - on demand reservation, specify region & Availability Zone
Reserved instances offer either a 1 year or 3 year term commitment. So on demand-instances would satisfy the need above. The answer is D , as the question also requires availability zones.
On-demand capacity instances in the required region and required availability zones is the most suitable here.
A Opção D (Reserva de capacidade sob demanda especificando a região e as zonas de disponibilidade) é a melhor solução, pois garante a capacidade necessária nas zonas de disponibilidade específicas para um evento de curta duração, atendendo ao requisito de forma eficiente e econômica.
Reserved Instances – Reduce your Amazon EC2 costs by making a commitment to a consistent instance configuration, including instance type and Region, for a term of 1 or 3 years. Capacity Reservations – Reserve capacity for your EC2 instances in a specific Availability Zone. do not confuse
