NEW QUESTION # 36
When does a network host make an ARP request? (Select one.)

  • A. To find the IP address of the default gateway
  • B. To find the IP address associated with a MAC address
  • C. To find the hostname associated with an IP address
  • D. To find the IP address associated with a hostname
  • E. To find the MAC address associated with an IP address

Answer: E

Explanation:
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.


NEW QUESTION # 37
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.

  • A. True
  • B. False

Answer: A

Explanation:
When migrating configurations from one Firebox to another, restoring a backup image from the existing Firebox to the new one is a valid and efficient method. This approach will transfer all configuration settings, policies, and security settings to the new Firebox. After restoring the backup, you need to add the new feature key specific to the new Firebox, as feature keys are unique to each device. This method preserves the existing configurations while adapting the setup for the new hardware.


NEW QUESTION # 38
What does a Firebox configured with default firewall policies do with outbound traffic that does not have a configured route? (Select one.)

  • A. Denies the traffic
  • B. Sends the traffic to the default gateway
  • C. Drops the traffic
  • D. Sends the traffic to the loopback interface

Answer: C

Explanation:
When a Firebox is configured with default firewall policies and encounters outbound traffic that lacks a specified route, the Firebox will drop this traffic. In firewall configurations, if there's no matching route or policy, the traffic typically gets discarded by default to prevent unintended data leakage or unauthorized connections. This behavior is standard for most firewall devices to ensure secure handling of unconfigured paths.


NEW QUESTION # 39
What is true about this log message? (Select three.)

  • A. The traffic is allowed outbound through the Firebox
  • B. The Application Control service has identified the traffic as Gmail
  • C. The traffic is allowed inbound through the Firebox
  • D. The HTTPS proxy identified a TLS v1.3 connection to the inbox.google.com SNI domain
  • E. The Gateway AntiVirus service denied the email traffic because it matches the 18.254 virus signature

Answer: A,B,D

Explanation:
Application Control Identifying Gmail Traffic: Application Control is capable of identifying and categorizing applications based on traffic patterns and signatures. In this case, it recognizes Gmail traffic, which is a typical function of Application Control for managing and monitoring web applications. This functionality allows administrators to monitor and control access to applications based on organizational policies.
HTTPS Proxy Identifies TLS v1.3 Connection: The HTTPS proxy in Firebox can inspect and manage encrypted traffic by recognizing details such as the Server Name Indication (SNI) field in TLS connections.
By identifying a TLS v1.3 connection to the inbox.google.com domain, the HTTPS proxy provides additional monitoring and control capabilities over encrypted connections.
Traffic Allowed Outbound Through the Firebox: Given that the log indicates outbound traffic, this confirms that the connection is permitted by the Firebox's policies for outbound traffic. Outbound traffic control is crucial for managing access to external resources and ensuring that only authorized traffic exits the network.


NEW QUESTION # 40

  • A. You cannot run the Web Setup Wizard
  • B. Only one user can connect to the Internet through the Firebox
  • C. You cannot save configuration changes to the Firebox
  • D. You cannot upgrade the Firebox
  • E. You cannot configure subscription services

Answer: C,D,E

Explanation:
Without a feature key:
* Option A: Upgrades are restricted, as the device relies on the feature key to validate software entitlement.
* Option B: Subscription services like antivirus, IPS, or web filtering cannot be configured without the feature key, which activates these services.
* Option D: Configuration changes cannot be permanently saved to the Firebox without the feature key, limiting the device's functionality.
* Option C(Web Setup Wizard) andOption E(one user internet access) do not depend on the feature key and are not restricted in this scenario.


NEW QUESTION # 43
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.)

  • A. www.example.com
  • B. /example.com/
  • C. example.com/
  • D. *.example.com
  • E. /account.html

Answer: A,D

Explanation:
When using domain exceptions to bypass content inspection for specific websites on a Firebox, the format is critical. For the domain www.example.com/account.html, two viable exception formats are:
* A. *.example.com: This wildcard format will include all subdomains of example.com, covering www.
example.com as well as any other subdomains like api.example.com. This format is useful when you need to exclude an entire domain and its subdomains from content inspection.
* D. www.example.com: This specifies the exact domain. Adding this as an exception will directly match www.example.com, making it suitable for bypassing content inspection on that specific subdomain.
Other formats, like /example.com/ or /account.html, do not match the required structure for domain name exceptions in the Firebox HTTP proxy settings.


NEW QUESTION # 44
You enable a network device monitoring application on a server with IP address 10.0.1.22. After you run the application, it reports that it cannot ping the Firebox at 10.0.1.1, and you see this log message in Traffic Monitor. What is the most likely cause of this issue? (Select one.)

  • A. The dynamic NAT statement is not configured correctly for the 10.0.1.0/24 subnet
  • B. The server IP address is on the Blocked Sites list
  • C. The default Unhandled Internal Packet policy is at the top of the policy set
  • D. There is no policy that allows Ping traffic from the server to the Firebox alias
  • E. There is no route on the Firebox for the 10.0.1.0/24 subnet

Answer: D

Explanation:
The most likely reason for the network device monitoring application's failure to ping the Firebox is the absence of an explicit policy permitting Ping traffic from the server (IP 10.0.1.22) to the Firebox alias (10.0.1.1). By default, Firebox policies are configured to allow only traffic explicitly permitted by a policy.
Therefore, without a dedicated policy allowing ICMP (Ping) requests from this specific source to the Firebox, the device will drop the traffic, resulting in a connectivity failure for Ping.
This is a common scenario in Firebox configurations, where restrictive policy settings enhance network security by blocking all traffic types unless specifically allowed.
