Demo Questions

Question 1

In the following output from top, which processes contribute to the percentage of time that the CPU spends in the state of wa?
Tasks: 193 total, 1 running, 190 sleeping, 2 stopped, 0 zombie
Cpu(s): 0.5%us, 0.3%sy, 0.0%ni, 98.2%id, 1.0%wa, 0.0%hi, 0.0%si, 0.0%st


  1. Processes waiting for user interaction.
  2. Processes that were already closed and are waiting to be launched again.
  3. Processes that have not been scheduled yet because they haven't been fully loaded into RAM or are inswap.
  4. Processes waiting for IO operations to complete.
Correct answer: D



Question 2

When is historical data of resource usage important? (Select THREE correct answers.)


  1. Predicting when resources will need to be increased.
  2. Selecting a computer vendor.
  3. Identifying processes killed during out of memory occurrences.
  4. Diagnosing capacity problems.
  5. Troubleshooting a software problem.
Correct answer: ADE



Question 3

Which of the following is a side effect of extensive usage of swap space?


  1. The root filesystem may become full because swap space is always located on the system root partition.
  2. The overall system performance may degrade because of heavy hard disk use and memoryreorganization.
  3. Since processes always exist completely in either RAM or swap, regular RAM may become unused if thekernel does not move processes back from the swap space to memory.
  4. The memory may become fragmented and slow down the access to memory pages. However, this canbe kept to a minimum by the regular use of memfrag -d.
  5. Applications need to restart because their virtual memory addresses change to reflect memory relocationto the swap address area.
Correct answer: B



Question 4

Which commands below are useful to collect data about remote filesystem connections? (Choose TWO correct answers.)


  1. pidstat
  2. nfsiostat

Question 5

Which command will report information on memory usage, paging and block input/output?


  1. free
  2. memshow

Question 6

What mechanism does collectd use to gather monitoring information on systems?


  1. It uses a library of plugins.
  2. A master server connects to a collectd service on each machine to retrieve the information.
  3. It collects its own information on each server and sends that to a master server.
  4. It makes SNMP queries to the clients being monitored.
Correct answer: A
