A user is asked to evaluate the data center to improve availability for customers. The user noticesthat there is only one ISP connection, some of the equipment is out of warranty, there are no spare parts, and no one was monitoring the UPS which was tripped twice in one month. Which three deficiencies in high availability has the user identified? (Choose three.)

A) failure to detect errors as they occur
B) failure to protect against poor maintenance
C) single points of failure
D) failure to prevent security incidents
E) failure to identify management issues

failure to detect errors as they occur

single points of failure

failure to design for reliability

Explanation:

When designing a data center, it is paramount that from the onset there must be high availability and there must be no single point of failure, as this can jeopardize all efforts put together to designing a data center. The presence of only one ISP connection is a failure to design for reliability, and as no one was monitoring the UPS is a failure to detect errors as they occur.
