### (406) Which option is not one of the methods used to submit an OPSCAP/SYSCAP report when voice lines are down?

• A.

SIPRNET.

• B.

NIPRNET.

• C.

Secure terminal.

• D.

Defense messaging system.

B. NIPRNET.
Explanation
The correct answer is NIPRNET. NIPRNET (Non-classified Internet Protocol Router Network) is a network used for unclassified communication and is not a method used to submit an OPSCAP/SYSCAP report when voice lines are down. The other options, SIPRNET (Secret Internet Protocol Router Network), secure terminal, and defense messaging system, are all methods that can be used to submit the report in such a situation.

### (406) A human evaluation is accomplished in a ground-based missile warning site report to

• A.

Make an assessment of the data itself.

• B.

Make an assessment of the system itself.

• C.

Determine if an event was generated by equipment malfunction only.

• D.

Determine if an L&PI was falsely generated by equipment malfunction, environment, or personnel.

D. Determine if an L&PI was falsely generated by equipment malfunction, environment, or personnel.
Explanation
In a ground-based missile warning site report, a human evaluation is conducted to determine if an L&PI (Launch and Predicted Impact) was falsely generated by equipment malfunction, environment, or personnel. This evaluation aims to identify any false alarms or erroneous information that may have been caused by these factors. It helps ensure the accuracy and reliability of the missile warning system by ruling out any false detections or errors that could potentially lead to unnecessary actions or panic.

### (406) When does a ground-based site initiate VOICETELL procedures?

• A.

Immediately after each event.

• B.

After 120 seconds of the beginning of event.

• C.

Only under the direction of Joint Space Operations Center.

• D.

If the Missile Correlation Center (MCC) does not receive the data.

D. If the Missile Correlation Center (MCC) does not receive the data.
Explanation
If the Missile Correlation Center (MCC) does not receive the data, a ground-based site initiates VOICETELL procedures. This suggests that VOICETELL procedures are only initiated when there is a failure in transmitting data to the MCC.
