To redirect requests for malicious domains to a specific IP address to alert the administrator.. DNS Sinkhole redirects a malicious DNS query to a fake IP address to identify compromised hosts.

Answer

To encrypt DNS traffic between the firewall and the ISP.

Answer

To allow a firewall to act as a DNS server for internal clients.

Answer

To cache DNS queries to improve network performance.

Question 9

You are configuring Advanced URL Filtering. Users report that a site is being blocked, but the category is 'Newly Registered Domains'. How can you allow access to this specific site while keeping the policy for other newly registered domains?

Accepted Answer

Add the site to the 'Allow List' in the URL Filtering profile object assigned to the security policy.. URL Filtering allows for category overrides within a profile to exempt specific sites from broad category-based blocking.

Answer

Move the security policy to the top of the policy list.

Answer

Add the site to the 'Blocked' list in the URL Filtering profile.

Answer

Create a new URL category and add the domain to it, then block that category.

Question 10

A company is experiencing high false-positive rates with WildFire for custom proprietary executable files. What is the recommended configuration to minimize these while maintaining security?

Accepted Answer

Create a WildFire analysis profile and add the proprietary file hashes to the WildFire File Exclusion list.. Submission of custom binaries to WildFire can be refined using exclusion lists and specific file type profiles.

Answer

Lower the threat prevention action from block to alert for all executables.

Answer

Disable WildFire on the specific security policy rule.

Answer

Change the WildFire forwarding location to a local WildFire appliance.

Question 11

An administrator needs to enable Threat Prevention to protect against a specific zero-day exploit. How are the signatures for these new threats delivered to the firewall?

Accepted Answer

Through the scheduled 'Threats' dynamic update package.. Threat Prevention signatures are delivered via dynamic updates, specifically 'Threats' updates, which are pushed to the firewall.

Answer

By manually downloading the threat signature database from the Customer Support Portal.

Answer

Through the daily WildFire update package.

Answer

By enabling the 'Automatic Update' feature in the Device > Software menu.

Question 12

Which action is required to ensure that WildFire analysis results are applied to traffic as quickly as possible?

Accepted Answer

Configure the WildFire profile to use the 'Real-time' analysis mode.. Enabling the 'Real-time' setting in the WildFire profile ensures files are sent and results are acted upon immediately.

Answer

Enable 'Packet Capture' for all security policies.

Answer

Increase the WildFire cloud region to the nearest geographic site.

Answer

Set the WildFire forwarding to 'Legacy' mode.

Question 13

You are deploying Advanced URL Filtering. How does the 'Credential Phishing' prevention feature operate?

Accepted Answer

It detects and blocks the submission of enterprise credentials to untrusted or newly registered websites.. Advanced URL Filtering inspects HTTP POST requests and uses URL categorization to detect and block credential theft.

Answer

It analyzes the URL to determine if it is a known malicious site.

Answer

It requires an agent installed on the endpoint to monitor browser activity.

Answer

It monitors all inbound traffic for known phishing signatures.

Question 14

How does the 'Advanced URL Filtering' subscription improve upon standard URL Filtering?

Accepted Answer

It provides real-time, cloud-based analysis of unknown or newly registered domains.. Advanced URL Filtering uses real-time analysis rather than just static database lookups to identify malicious sites.

Answer

It allows the firewall to bypass SSL decryption for certain categories.

Answer

It includes an integrated VPN client for remote workers.

Answer

It allows for more custom URL categories.

Question 15

Where is the configuration located to enable the 'DNS Security' service on a specific security zone?

Accepted Answer

Policies > Security > [Rule Name] > Actions tab. DNS Security profiles are applied to security policy rules, which then process traffic from specific zones.

Answer

Objects > Security Profiles > DNS Security

Answer

Network > Zones > [Zone Name]

Answer

Device > Setup > Services > DNS

Question 16

When managing infrastructure, what is the best practice for handling 'Security Profile Groups'?

Accepted Answer

Use a common group for similar traffic types to ensure consistent security policy enforcement.. Security Profile Groups allow for standardized enforcement across multiple rules, simplifying management and updates.

Answer

Only apply groups to traffic destined for the Internet.

Answer

Avoid using groups and always apply individual profiles to rules.

Answer

Create a unique group for every single security policy rule.

Question 17

What is the impact of selecting 'Action: Reset-Both' in a Threat Prevention profile for a detected vulnerability?

Accepted Answer

It sends a TCP RST to both the client and the server to terminate the connection.. Reset-Both terminates the TCP session from both the client and the server sides, immediately stopping the malicious traffic.

Answer

It blocks the source IP address for a specified duration.

Answer

It drops the packet but allows the TCP session to continue.

Question 18

An administrator finds that the 'Threat Prevention' logs are not showing any data, despite having an active subscription. What is the most likely cause?

Accepted Answer

The security policy rules do not have an attached Security Profile Group.. Threat prevention logs are generated by policy rules; if a rule does not have a security profile attached, no logs are generated.

Answer

The 'Threats' dynamic update is not scheduled.

Answer

The firewall is in 'Evaluation Mode'.

Answer

The log forwarding profile is missing the 'Global' setting.

Question 19

A user is blocked by a URL Filtering profile. Where can you find the specific log entry that explains why the block occurred?
