A. B. C. D.D.
A reservation guarantees to a cloud customer that they will have access to a minimal level of resources to run their systems, which will help mitigate against DoS attacks or systems that consume high levels of resources.
A reservation pertains to memory and CPU resources.
Under the concept of a reservation, memory and CPU are the guaranteed resources, but storage and networking are not included even though they are core components of cloud computing.
Software would be out of scope for a guarantee and doesn't really pertain to the concept.
The concept of "reservation" in cloud computing refers to the ability to reserve a certain amount of computing resources in advance, guaranteeing that these resources will be available when needed, regardless of other users' demand for resources. To achieve this, the cloud provider may offer different types of reservation services, such as reserved instances, reserved capacity, or dedicated hosts.
To answer the question, we need to identify which set of services would compromise the reservation if a customer wishes to guarantee that a minimum level of resources will always be available. The options provided are:
A. Memory and networking B. CPU and software C. CPU and storage D. CPU and memory.
Out of these options, the services that are most likely to affect resource reservation are CPU and memory. CPU (Central Processing Unit) is the primary computing resource in a cloud environment, responsible for executing instructions and performing calculations. Memory, on the other hand, is the temporary storage space used by the CPU to hold data and instructions while they are being processed.
If a cloud customer wishes to guarantee a minimum level of resources, they are essentially asking for a guaranteed amount of CPU and memory resources. If either of these resources is not available when needed, the customer's application performance may suffer or even fail. Therefore, any compromise in the reservation of CPU and memory resources would directly impact the customer's ability to meet their performance requirements.
Option A (memory and networking) may affect application performance, but it is less likely to impact resource reservation since networking is typically not a reserved resource in cloud environments.
Option B (CPU and software) is also less likely to affect resource reservation since software is not a computing resource, and it can be installed and configured independently of the cloud infrastructure.
Option C (CPU and storage) may impact application performance if the storage subsystem is slow or overloaded, but it is not directly related to resource reservation.
Therefore, the best answer to the question is D, CPU and memory.
