질문 # 22
You want to send traffic from the Internet to your internal web server through the Firebox. You see the traffic is allowed in Traffic Monitor, but the web server cannot be reached. You use the TCP Dump Diagnostic Task and collect this information from the Firebox interface connected to the web server. What could cause the problem? (Select two.)
정답：B,D
설명：
Comprehensive Technical Explanation:
When Traffic Monitor verifies that inbound traffic is allowed and a TCP Dump capture on the internal interface confirms the Firebox transmitted the translated SYN packets toward the web server, the Firebox has completed its ingress policy evaluation and packet forwarding. If the client cannot establish a connection, the failure points to the destination host or its local return path:
1. Host-based firewall software: A local firewall running on the server (such as Windows Defender Firewall or iptables) may be discarding incoming TCP SYN packets on port 80/443 from external IP addresses (Option A).
2. Misconfigured default gateway on the server: When the server attempts to reply with a TCP SYN-ACK, it must send the response back through the Firebox so the Firebox can un-NAT the packet. If the server's default gateway is missing, invalid, or pointed to a different router, the return packet bypasses the Firebox or is dropped, breaking the three-way handshake (Option E).
Option B is eliminated because Traffic Monitor already confirmed the connection was allowed. Option C is incorrect because inbound access uses Static NAT, not Dynamic NAT. Option D is incorrect because an IP on the Blocked Sites list would be denied at the external interface before entering the internal network.

질문 # 23
What steps must you take to send log messages from a Firebox to WatchGuard Cloud? (Select two.)
정답：D,E
설명：
* Enable WatchGuard Cloud in Firebox Configuration: To send log messages to WatchGuard Cloud, you need to activate WatchGuard Cloud integration within the Firebox's configuration settings. This action prepares the device to communicate with WatchGuard Cloud and transfer log data.
* Use the WatchGuard Cloud Add Device Wizard: The Add Device wizard in WatchGuard Cloud is used to register and connect the Firebox to WatchGuard Cloud. This wizard guides administrators through the setup and ensures that the device is correctly configured to send logs and other data to the cloud.
These steps are required to establish connectivity and ensure that log messages are sent to WatchGuard Cloud.
Other options, such as adding an FQDN or configuring Dimension synchronization, are not necessary for this task.
질문 # 24
You can add your Firebox to WatchGuard Cloud but continue to manage it locally. When you do this, what additional features does WatchGuard Cloud provide for your locally-managed Firebox? (Select two.)
정답：C,D
설명：
When adding a Firebox to WatchGuard Cloud while maintaining local management:
* Option B: WatchGuard Cloud allows the scheduling of Firebox firmware updates, which provides flexibility in managing update timing without disrupting operations.
* Option E: It provides live status updates and reporting access, giving insights into device health and performance metrics for informed management decisions.
* Option A(Automatic firmware updates) is typically managed manually in a locally managed configuration.
* Option C(Real-time network traffic data) andOption D(Unified event correlation andanalysis) are advanced features that require full cloud management rather than hybrid (local/cloud) setup.
질문 # 25
Match the network server to the protocol and port it uses:
정답：
설명：
Explanation:
Comprehensive Technical Explanation:
Standard TCP/IP network application protocols rely on well-known transport layer ports standardized by IANA and recognized throughout Fireware policies. Dynamic Host Configuration Protocol (DHCP) operates over User Datagram Protocol (UDP), utilizing UDP destination port 67 on the server/relay agent and UDP destination port 68 on client endpoints to negotiate dynamic address configurations without prior layer-3 identity. Simple Mail Transfer Protocol (SMTP) employs Transmission Control Protocol (TCP) port 25 for reliable, connection-oriented message delivery between mail transfer agents (MTAs). The Domain Name System (DNS) resolves human-readable names to network addresses primarily via UDP port 53 for lightweight transactional lookups, utilizing TCP port 53 for transactions exceeding standard packet sizing limits or zone transfers. Hypertext Transfer Protocol (HTTP) serves unencrypted web communication over cleartext TCP port 80. In contrast, Hypertext Transfer Protocol Secure (HTTPS) secures transport data by layering TLS encryption over TCP port 443. In Fireware, these ports correspond directly with built-in policy templates and packet filters (e.g., DNS, HTTP, HTTPS, and DHCP-client/server definitions), ensuring accurate traffic inspection and enforcement boundaries across physical and virtual interfaces.

질문 # 26
You have five public IP addresses available from your ISP. When you create a Static NAT action, you want to specify one of the public IP addresses for inbound traffic but do not see it in the IP address drop-down list.
How can you change the Firebox configuration to see additional public IP addresses in the Static NAT action?
(Select one.)
정답：A
설명：
Comprehensive Technical Explanation:
In WatchGuard Fireware, a Static NAT (SNAT) action requires the public-facing external IP address to belong to the Firebox so the appliance can respond to ARP requests on the ISP subnet and accept incoming packets addressed to that destination. When defining the external IP in an SNAT dialog, the drop-down menu populates exclusively with IP addresses configured on the Firebox's external interfaces.
If an ISP provides a block of multiple public IP addresses (such as a /29 subnet with 5 usable public IPs), the primary IP of the external interface consumes only one address. To make the remaining four public IP addresses available across Fireware configuration dialogs-including the SNAT interface list-the administrator must navigate to Network > Interfaces, edit the external interface, and add the extra public IP addresses as Secondary IP Addresses. Once configured as secondary IPs on the external interface, they immediately appear in the drop-down selection list when creating or modifying Static NAT actions.
