Users cannot download a PDF file from your intranet. You know the file is safe to download. When you review the log messages, you see that IntelligentAV identified the file as malicious. The only way to resolve this is to change the file extension.
正解：B
解説：
Comprehensive Technical Explanation:
IntelligentAV is an artificial intelligence-driven scanning engine that uses predictive machine learning models to analyze the binary structure and characteristics of files to determine whether they pose a threat. It does not rely on simple file extensions; renaming a .pdf file to another extension does not bypass inspection, as the proxy engine determines file types based on actual file headers and MIME properties rather than superficial filename extensions.
If a legitimate internal file is misidentified as malicious (a false positive), changing its file extension is neither an effective nor an administrative resolution. Fireware provides multiple ways to resolve false positives:
- The administrator can configure an explicit exception within the IntelligentAV configuration by adding the cryptographic hash (SHA-256) of the trusted file to the IntelligentAV whitelist/exclusion list.
- An exception can be configured in the proxy action to bypass scanning for traffic originating from the trusted intranet server IP address.
- The file sample can be submitted to WatchGuard for threat classification review.
Therefore, the assertion that changing the file extension is the only way to resolve the issue is False.

Clients on the 10.0.10.0/24 network must connect to the server at 10.0.20.100. Based on this image, what static route must you add to the Firebox for traffic to reach the server? (Select one.)
正解：A
解説：
In this network configuration:
* The Firebox needs a static route to direct traffic intended for the 10.0.20.0/24 network (where the server
10.0.20.100 resides).
* The gateway address that allows the Firebox to reach the 10.0.20.0/24 network is 10.0.2.254, which is the router's IP address on the 10.0.2.0/24 network.
By configuring a static route:
* Destination: 10.0.20.0/24
* Gateway: 10.0.2.254
This route instructs the Firebox to send traffic destined for the 10.0.20.0/24 network via the router at
10.0.2.254, enabling clients in the 10.0.10.0/24 network to reach the server.
* Option Bis correct because it provides the correct destination and gateway for traffic to the 10.0.20.0
/24 network.
* Option Aincorrectly sets the route to 10.0.10.0/24, which doesn't address the server network.
* Options C and Dset incorrect gateways (10.0.2.1), which do not route traffic correctly in this setup.
* Option Eis a duplicate of B and would also be correct; thus, B and E are equivalent.
質問 # 40
If the Firebox does not have a feature key installed, which of these statements are true? (Select three.)
正解：B、C、D
解説：
Comprehensive Technical Explanation:
A Firebox feature key is a cryptographically signed text file issued by WatchGuard that activates the Fireware operating system, unlocks licensed user limits, defines interface counts, and enables licensed security subscription services. When a Firebox boots in a factory-default state or operates without a feature key installed, strict licensing enforcement rules apply:
1. Fireware restricts outbound Internet access: only one concurrent internal user can connect out to the Internet at a time (Option E).
2. The administrator cannot upgrade the Firebox OS version, as valid maintenance and software upgrade authorization are licensed via the feature key (Option A).
3. None of the subscription services (such as Gateway AntiVirus, IPS, WebBlocker, Application Control, or spamBlocker) can be configured or enabled (Option B).
However, administrators are permitted to run the Web Setup Wizard (Option C) to establish initial administrative connectivity, and they can save local system configuration changes (such as interface IPs and admin passphrases) to the Firebox hardware (refuting Option D).

質問 # 41
After you enable content inspection, your users cannot connect to the business-critical website www.example.
com/account.html hosted by a trusted partner. To try to resolve this issue, you added a Domain Name exception of www.example.com/account.html, but users still cannot connect to the website. What is the Domain Name exception format to add to the HTTP proxy to correctly resolve this issue? (Select two.)
正解：A、B
解説：
Comprehensive Technical Explanation:
When configuring an HTTPS Proxy Action with Content Inspection enabled, the Firebox evaluates bypass rules under the Domain Name Exceptions list. These exceptions instruct the proxy engine to skip certificate interception and deep decryption for specified hostnames. In TLS negotiation, the Firebox reads the target destination from the Server Name Indication (SNI) extension header during the initial Client Hello handshake or extracts the Common Name (CN) from the server's certificate.
Crucially, the TLS SNI and CN fields contain solely the Fully Qualified Domain Name (FQDN) of the destination server (e.g., www.example.com); they never include uniform resource identifier (URI) paths, file names, or trailing directory slashes (such as /account.html). Entering www.example.com/account.html fails because path information is not visible until the connection is decrypted. Therefore, domain name exceptions must be formatted using exact host FQDNs or wildcards:
- Option D (www.example.com) directly matches the specific host header requested by the browser.
- Option A (*.example.com) utilizes a wildcard pattern that encompasses www.example.com along with any other subdomains.
Options B, C, and E include path slashes and directories, which are invalid for TLS domain name exception matching.

質問 # 42
When you configure a Branch Office VPN tunnel to a third-party device, AES-GCM encryption is recommended for:
正解：D
解説：
Comprehensive Technical Explanation:
In IPSec Phase 1 and Phase 2 proposals, traditional encryption suites rely on Cipher Block Chaining (CBC) modes (such as AES-CBC 128 or 256-bit) paired with a separate hashing algorithm (such as SHA-256) to achieve confidentiality and packet integrity authentication. This requires two sequential mathematical operations per packet.
Galois/Counter Mode (AES-GCM) is an Authenticated Encryption with Associated Data (AEAD) cipher that combines encryption and authentication into a single algorithm. Modern Firebox CPUs and enterprise third- party VPN hardware incorporate specialized hardware acceleration (such as Intel AES-NI instruction sets) optimized for parallel processing under GCM. As a result, when both VPN endpoints support AES-GCM (available in AES-GCM-128 and AES-GCM-256), the cryptographic overhead is reduced, latency decreases, and VPN throughput increases. Because GCM provides equivalent or superior cryptographic security while lowering CPU overhead, WatchGuard recommends AES-GCM for performance gains whenever third-party hardware supports it.
