If a cloud computing customer wishes to guarantee that a minimum level of resources will always be available, which of the following set of services would compromise the reservation? 

Answer options:

A. Memory and networking
B. CPU and software
C. CPU and storage
D. CPU and memory

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.
