Watchguard Network Security Practice Test

After enabling spamBlocker, what could prevent its effectiveness if improperly configured?

1. SpamBlocker Virus Outbreak Detection is enabled.

2. Connections cannot be resolved to spamBlocker servers.

3. The spamBlocker action for Confirmed Spam is set to Block.

4. SMTP proxy is disabled.

The correct answer is: Connections cannot be resolved to spamBlocker servers.

The effectiveness of spamBlocker can be significantly hindered if connections cannot be resolved to spamBlocker servers. This is because spamBlocker relies on real-time communication with its servers to identify and filter out spam effectively. If the system is unable to resolve these connections, it will not have access to the latest spam identification techniques, threat intelligence, or updates, which are essential for accurately categorizing and managing incoming messages. Consequently, without successful connections to these servers, the spamBlocker feature may struggle to function properly, potentially allowing spam to reach users' inboxes despite being enabled. In contrast, having the spamBlocker action for Confirmed Spam set to Block is actually a correct configuration that aids in effectiveness, while having Virus Outbreak Detection enabled does not impede spam filtering directly. Additionally, with the SMTP proxy disabled, it could restrict spamBlocker's ability to process email traffic appropriately, but it does not impact server connections in the same way that inability to resolve connections does.
