最新的 Locally-Managed Fireboxes Network-Security-Essentials 免費考試真題 (Q44-Q49):

問題 #44
When does a network host make an ARP request? (Select one.)

答案：A

解題說明：
The Address Resolution Protocol (ARP) is used to map an IP address to a physical machine (MAC) address on a local network. When a device wants to communicate with another device on the same local network, it uses an ARP request to discover the MAC address associated with a known IP address. The ARP process is essential for IP-based communication within the same network segment.
* Option Dis correct because ARP's primary function is to find the MAC address associated with an IP address.
* Other options mention IP addresses or hostnames, which would be resolved using other methods like DNS, not ARP.


問題 #45
What steps must you take to send log messages from a Firebox to WatchGuard Cloud? (Select two.)

答案：A,C

解題說明：
Comprehensive Technical Explanation:
Enabling a locally-managed Firebox to deliver encrypted logs to WatchGuard Cloud requires registering the device within the cloud platform and activating the connection locally on Fireware:
1. First, an administrator must log in to the WatchGuard Cloud web portal and execute the Add Device wizard. This wizard registers the appliance serial number under the WatchGuard Cloud account and generates a unique, device-specific verification registration code / connection string (Option E).
2. Second, within the local Firebox configuration (via Policy Manager or Fireware Web UI), the administrator navigates to the WatchGuard Cloud configuration settings, selects the option to Enable WatchGuard Cloud, and enters the generated verification code to establish the secure connection (Option A).
Once connected over outbound TCP port 443, the Firebox authenticates and streams log data directly to the cloud. Administrators do not manually enter cloud FQDNs into the legacy Log Server list (eliminating Option B), there is no global shared Authentication Key used across appliances (eliminating Option C), and Dimension operates independently without synchronizing logs to WatchGuard Cloud (eliminating Option D).

問題 #46
The Firebox can scan the contents of encrypted zip files with Gateway AntiVirus when HTTPS content inspection is enabled.

答案：A

解題說明：
Comprehensive Technical Explanation:
Enabling HTTPS content inspection allows the Firebox to act as an outbound man-in-the-middle proxy, terminating the external TLS tunnel, decrypting the payload, and exposing cleartext HTTP streams to integrated scanning engines. When a transferred archive file is passed to Gateway AntiVirus (GAV), the scanning engine unpacks supported compressed archive formats (such as standard .zip, .tar, or .gz) to examine the embedded files against its signature database. However, if a zip file is independently encrypted with a password or cryptographic key, the contents within the archive container remain ciphertext. The Firebox and GAV engine do not possess the decryption password or key required to unpack the archive. Consequently, the scanner cannot inspect the encapsulated files, regardless of whether the outer transport layer was decrypted via HTTPS content inspection. In Fireware proxy configurations, administrators can specify default actions (such as Allow, Deny, or Lock) under the Gateway AntiVirus or proxy archive settings specifically for files that cannot be scanned, including password-protected or encrypted archives.

問題 #47
You have just configured Mobile VPN with IKEv2 for your customer. By default, authenticated Mobile VPN users are allowed to send traffic to all Firebox networks through the VPN.

答案：A

解題說明：
Comprehensive Technical Explanation:
When Mobile VPN with IKEv2 is enabled on a Firebox, Fireware does not grant unrestricted access to all local interfaces by default. Instead, Fireware automatically creates a specific policy named Allow-IKEv2- Users. By default, this generated policy defines:
- From: IKEv2-Users (the built-in user group for authenticated IKEv2 clients).
- To: Any-Trusted.
Because the default policy allows traffic strictly destined for Any-Trusted, authenticated Mobile VPN users can initially communicate only with resources located on Firebox Trusted interfaces. They are not permitted to reach Optional interfaces, Custom interfaces, or route through to external networks unless an administrator modifies the Allow-IKEv2-Users policy destination list (e.g., adding Any-Optional or Any) or configures custom firewall policies. Furthermore, in the IKEv2 network settings, only the routes defined in the VPN configuration are pushed to the client. Therefore, the statement is False.
Reference: WatchGuard Network Security Essentials - Networking, Policies, and NAT: Mobile VPN with IKEv2 Default Policy and Access Control Boundaries.

問題 #48
You bought a new Firebox and want to use the configuration from an existing Firebox you already configured. The best way to migrate the configuration is to restore a backup image from the existing Firebox to the new Firebox, then add the new feature key.

答案：A

解題說明：
Comprehensive Technical Explanation:
Restoring a backup image (.fbi) from one Firebox to a completely different physical unit is strongly discouraged and unsupported across different hardware models. A Firebox backup image creates a hardware- level clone that contains the original device's unique physical MAC addresses, component drivers, hardware interface layouts, and serial-number-bound feature key. Restoring a backup image onto non-identical hardware can lead to operating system boot failures, interface mapping mismatches, or network corruption.
Furthermore, a backup image can only be restored to hardware sharing the exact same model platform and serial number parameters.
The officially recommended, best-practice procedure for migrating an existing configuration to a new Firebox involves using Policy Manager:
1. Open the existing active configuration file in Policy Manager and save it as an XML file.
2. In Policy Manager, select File > SaveTo > Firebox, directing the save operation to the IP address of the new Firebox.
3. Policy Manager automatically strips hardware-specific MAC addresses, retains policies, aliases, and network definitions, and prompts the administrator to enter or download the unique feature key assigned specifically to the new hardware serial number.
