Question

When working on the costing for on-demand ec2 instances, which of the following are attributes that determine the cost of the instance? choose all that apply.

A) Time of day.
B) Geographic location.
C) Instance type.
D) Internet speed.

Answer 1

On-demand EC2 instance costs are influenced by geographic location and instance type, while time of day is not a factor and internet speed impacts data transfer costs separately.

Step-by-step explanation:

When working on the cost for on-demand EC2 instances on Amazon Web Services (AWS), several factors determine the cost. Notably, the following attributes significantly impact the pricing:

• B) Geographic location: Different AWS regions may have varying prices due to operational costs and demand in those regions.
• C) Instance type: This determines the hardware specifications of the EC2 instance, including CPU, memory, storage, and networking capacity. Different instance types come with different pricing.

While the time of day does not typically impact the cost of an on-demand EC2 instance, aspects such as reserved instances or spot instances might offer lower prices depending on time-based demand. Internet speed, specifically the data transfer rate, can affect costs but is not directly tied to the instance type and is billed separately.

Answer 2

The attributes that determine the cost of on-demand EC2 instances are time of day, geographic location, and instance type.

Step-by-step explanation:

The attributes that determine the cost of on-demand EC2 instances are:

1. Time of day: The cost of EC2 instances can vary based on the time of day. For example, instances may be more expensive during peak hours when there is high demand.
2. Geographic location: The cost of instances can also vary based on the region or availability zone they are deployed in. Different regions have different pricing for EC2 instances.
3. Instance type: The cost of EC2 instances depends on the type of instance you choose. Different instance types have different performance characteristics and pricing.
