Explanation.

Compute resources such as CPU, memory, and Ethernet ports need to be monitored to ensure that they are operating within acceptable thresholds. This can be done by defining threshold policies, which specify the range of values that are considered normal for a particular statistic. If a statistic falls outside of this range, an alert can be generated to indicate that there may be a problem.

To define a threshold policy for a compute resource, you need to select the appropriate statistic classes. Two statistic classes that can be used are:

1. Memory failures: This statistic class measures the number of memory errors that occur on a compute resource. Memory errors can be caused by a variety of factors, including faulty hardware, software bugs, and environmental factors. By monitoring memory failures, you can detect when a compute resource is experiencing memory errors and take appropriate action to address the problem.

2. Processor runtime: This statistic class measures the amount of time that a processor spends executing instructions. This can be useful for identifying performance bottlenecks, as well as detecting when a processor is under heavy load and may be at risk of overheating or failing.

Ethernet port statistics can also be used to define a threshold policy, as they provide information about the performance of the network connection. This can be useful for identifying network congestion or other issues that may be impacting the performance of a compute resource.

Ethernet port CRC stats specifically measure the number of cyclic redundancy check (CRC) errors that occur on a particular Ethernet port. CRC errors can be caused by a variety of factors, including faulty cabling or network equipment, electromagnetic interference, or software bugs. By monitoring CRC stats, you can detect when a network connection is experiencing errors and take appropriate action to address the problem.

Processor lock ups AE refers to the number of times a processor has been locked up, which can be caused by a variety of factors such as hardware failure, software bugs, or environmental factors. This statistic class can be useful for identifying when a processor is experiencing issues and may need to be restarted or replaced.

Therefore, the correct answers to the question are D (processor runtime) and C (Ethernet port stats).
