NEW QUESTION # 18
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.)
Answer: E
Explanation:
Comprehensive Technical Explanation:
Under 802.1Q VLAN encapsulation standards, an Ethernet interface can send and receive frames that carry a
4-byte 802.1Q VLAN tag (tagged) or carry no tag header (untagged). When connecting a Firebox interface to an intermediate managed network switch over an 802.1Q trunk link carrying multiple virtual networks, the interface configuration on the Firebox must match the trunk configuration on the switch port.
The topology diagram shows the physical link between the Firebox and the switch carrying:
- VLAN 10 Tagged
- VLAN 20 Tagged
Because the switch forwards frames for both VLAN 10 and VLAN 20 across that uplink with IEEE 802.1Q headers intact, the Firebox physical interface must be configured as a member of VLAN 10 (Tagged) and VLAN 20 (Tagged). This ensures the Fireware network driver processes 802.1Q tags, demultiplexes incoming frames to their respective virtual VLAN sub-interfaces (vlan10 and vlan20), and tags outbound return traffic appropriately.

NEW QUESTION # 19
If you have only one public IP address, can you use Static NAT to enable inbound connections to both an email server and a web server on the private network? (Select one.)
Answer: B
Explanation:
Comprehensive Technical Explanation:
Static NAT (SNAT) operates at Layer 4 (Transport layer) in addition to Layer 3 (Network layer), performing port-based forwarding. A single public IPv4 address assigned to a Firebox external interface can forward incoming connections to multiple distinct internal hosts provided that each service utilizes a different destination TCP/UDP port number.
In this scenario, incoming email traffic (SMTP) arrives on TCP port 25, while web server traffic arrives on TCP port 80 (HTTP) or TCP port 443 (HTTPS). Because these applications listen on distinct port numbers, an administrator can author two separate policies:
1. An SMTP policy with To: [SNAT action mapping public IP:25 to internal email server 10.0.1.10].
2. An HTTPS policy with To: [SNAT action mapping public IP:443 to internal web server 10.0.1.20].
Because the Firebox inspects the destination port in the TCP header, it steers incoming packets to the correct internal server.

NEW QUESTION # 20
Your network was the target of an attack last week. You want to learn more about the source of the attack.
What monitoring tools can you use to get started? (Select one.)
Answer: E
Explanation:
To investigate an attack and learn more about the source,Log Search and reports in WatchGuard Cloud or Dimensionoffer detailed logs and analytical reports. These tools provide historical data, allowing you to review traffic, pinpoint the source of the attack, and analyze patterns.
While other tools like Traffic Monitor or FireWatch offer real-time monitoring, they do not provide the in- depth historical analysis and reporting features required for post-incident investigation.
NEW QUESTION # 21
You configured your Firebox interfaces and routes and want to verify the status of the routes and connected hosts. You found this information in Firebox System Manager > Status Report. What is true about the IPv4 routes and ARP table in this deployment? (Select one.)
Answer: C
Explanation:
Analyzing the routing table and ARP table in the provided image:
* Routing Table Analysis:
* The route 0.0.0.0 with a gateway of 198.51.100.1 on the eth0 interface suggests this is the default route for outbound traffic, indicating that the Firebox's public interface (eth0) is configured to route traffic through this gateway.
* This confirms that the Firebox is publicly reachable at the IP address 198.51.100.1.
* ARP Table Analysis:
* The ARP entry for the gateway IP 198.51.100.1 is not directly shown in the image but could typically be resolved to verify connectivity.
* Other options provided, such as MAC address validation, do not correspond with the current ARP entries shown in the image.
This setup indicates that the Firebox is accessible publicly on the eth0 interface using the IP 198.51.100.1, makingOption Athe correct answer.
NEW QUESTION # 22
In the network configuration shown in this image, which aliases include Eth2 as a member? (Select three.)
Answer: A,B,D
Explanation:
In the network configuration image provided, the interfaceOptional-1is mapped toEth2. Here's how the aliases work:
* Optional-1: Directly includes Eth2 since it's configured as Optional-1 in the network configuration.
* Any-Optional: This alias includes all optional interfaces, which would cover Eth2 as it is associated with Optional-1.
* Any: The "Any" alias includes all interfaces on the Firebox, covering all Trusted, Optional, and External interfaces. Thus, Eth2 is part of this alias by default.
Aliases likeAny-TrustedandAny-Externalwould not include Eth2 since it is configured as an Optional interface, not Trusted or External.
NEW QUESTION # 23
