質問 # 31
You have an existing network infrastructure built out that uses tagged and untagged VLAN networks. Based on the diagram below, which VLANs must you add to the Firebox interface? (Select one.)
正解：D
解説：
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.
質問 # 32
Match the network server to the protocol and port it uses:
正解：
解説：
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.

質問 # 33
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.)
正解：A、B
解説：
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.

質問 # 34
If a Firebox has two trusted interfaces enabled, the default policies allow HTTPS connections between computers on different trusted networks.
正解：A
解説：
Comprehensive Technical Explanation:
In WatchGuard Fireware OS, default firewall policy generation enforces strict default-deny boundaries to isolate internal network segments. When multiple trusted or optional interfaces are configured, the standard default outbound policies (such as the default Outgoing packet filter or default TCP-UDP-out / HTTP-out / HTTPS-out policies) designate Any-Trusted or Any-Optional in the From list, but explicitly specify Any- External in the To list.
Because Any-External only includes interfaces configured as External network types, the default policies do not match traffic where both the source and the destination reside on internal interfaces (such as between Trusted Interface 1 and Trusted Interface 2). Inter-network internal traffic fails to match these outbound policies and matches the default Unhandled Internal Packet rule, which silently drops the connection. To permit HTTPS or any other protocol between hosts across two distinct trusted networks, an administrator must explicitly author a custom policy with From: [Trusted-1] (or Any-Trusted) and To: [Trusted-2] .

質問 # 35
Match each type of NAT with the correct descriptor
正解：
解説：
Explanation:
Here are the correct answers for matching each NAT type with its descriptor:
* Changes incoming packets sent to a public IP address to different internal IP addresses based on the destination portanswer:Static NAT Explanation: Static NAT maps a public IP address to multiple internal IP addresses based on the port, allowing specific services or applications to be routed to various internal destinations.
* Allows a user on the trusted or optional network to connect to a public server that is on the same physical Firebox interface by its public IP address or domain nameanswer:NAT loopback Explanation: NAT loopback (or NAT reflection) allows internal users to access a public IP address or domain name that resolves to the same local network, making it appear as if they are connecting from outside the network.
* Conserves IP addresses and hides the internal topology of your networkanswer:Dynamic NAT Explanation: Dynamic NAT (or PAT - Port Address Translation) conserves public IP addresses by allowing multiple internal devices to share a single public IP address. This setup is commonly used for outbound internet connections from a private network.
* Changes all incoming and outgoing packets sent from one range of addresses to a different range of addressesanswer:1-to-1 NAT Explanation: 1-to-1 NAT maps each internal IP address to a unique public IP address, providing a one-to-one relationship. This type of NAT is often used for networks that require external access to specific internal resources.
