Watchguard Network Security Practice Test

If users experience no reduction in spam after enabling spamBlocker, what could be a possible reason?

1. DNS is not configured on the Firebox.

2. The spamBlocker action for Confirmed Spam is set to Allow.

3. The Maximum File Size to Scan option is set too high.

4. A spamBlocker exception is configured to allow all traffic from certain senders.

The correct answer is: The Maximum File Size to Scan option is set too high.

While the choice regarding the Maximum File Size to Scan suggests that large files might be overlooked, the most pertinent reason why users experience no reduction in spam after enabling spamBlocker lies in the configuration of the spamBlocker action for Confirmed Spam being set to Allow. When the spamBlocker is enabled, it is designed to filter out unwanted spam messages effectively. However, if the action for Confirmed Spam is configured to Allow, this means that any messages identified as confirmed spam will not be blocked but instead allowed through to the user’s inbox. This directly results in no discernible reduction in spam, as the identified spam isn’t being filtered out as intended. Moreover, if exceptions are configured to allow all traffic from certain senders, it would also prevent spamBlocker from working effectively, as it may inadvertently allow spam from those exceptions. However, the primary and most immediate issue would be the configuration of actions for confirmed spam that counteracts the purpose of enabling the spamBlocker. Thus, proper configuration of the spamBlocker actions is crucial in ensuring it functions to effectively reduce spam, which highlights why attention must be paid to these settings to achieve the desired outcome in spam management.
