Based on the diagram provided, the Firebox connects to a switch with VLAN 10 and VLAN 20 as tagged traffic. The connection between the Firebox and the switch shows that both VLAN 10 and VLAN 20 are tagged, indicating that traffic for these VLANs will be carried over a single trunk link to the Firebox.
To properly configure the Firebox to handle this setup, you need to addVLAN 10 TaggedandVLAN 20 Taggedto the Firebox interface, as this configuration will allow the Firebox to interpret tagged packets for both VLANs from the switch. Untagged configurations are not applicable here since the Firebox interface expects tagged traffic for both VLANs on the trunk connection.
NEW QUESTION # 29
The Firebox can scan the contents of encrypted zip files with Gateway AntiVirus when HTTPS content inspection is enabled.
- A. False
- B. True
Answer: A
Explanation:
The Firebox cannot scan the contents of encrypted zip files even if HTTPS content inspection is enabled.
HTTPS content inspection allows the Firebox to inspect encrypted HTTPS traffic by decrypting it. However, the content within encrypted zip files remains inaccessible to Gateway AntiVirus scanning because the encryption key for the zip file is not available to the Firebox. This limitation is consistent with standard network security practices, where encrypted files need to be decrypted with a known key before content scanning can occur.
