NetSec-Pro Infrastructure Management And CDSS Practice Test 1 — 15 Questions

Question 1

A network administrator needs to verify that the firewall is successfully communicating with the WildFire cloud service. Which CLI command provides the most relevant connectivity information?

Accepted Answer

show wildfire status. The 'test wildfire registration' command checks the current status of the connection to the WildFire cloud.

Answer

debug wildfire connectivity

Answer

show jobs id wildfire-sync

Answer

test wildfire cloud-reachability

Question 2

An administrator needs to ensure that only specific subdomains are permitted under a top-level domain while blocking the rest using DNS Security. Which configuration approach is most effective?

Accepted Answer

Create a DNS Security policy rule using a Custom DNS Signature to match the specific subdomains.. Custom DNS signatures allow for granular control over subdomain access beyond basic category filtering.

Answer

Configure a URL Filtering profile to block the top-level domain.

Answer

Enable DNS Security and rely on the default 'Command and Control' category block.

Answer

Add the full domain to the DNS sinkhole whitelist.

Question 3

A company uses a proxy server. How must the Palo Alto Networks firewall be configured to ensure 'Threat Prevention' is effective?

Accepted Answer

Enable X-Forwarded-For header inspection in the Security Profile.. When traffic passes through a proxy, the firewall sees the proxy's IP, not the original client. The firewall must be configured to identify the traffic correctly.

Answer

Disable SSL decryption for the proxy traffic.

Answer

Create a specific 'Proxy' zone and apply an App-ID policy.

Answer

Configure the proxy as a 'Trusted' source in the Device > Setup menu.

Question 4

An administrator wants to audit all security policies to see which ones are not currently using a 'Security Profile'. Which tool is best for this?

Accepted Answer

Policy Optimizer. The 'Policy Optimizer' tool is designed to identify unused or misconfigured policies, including those missing security profiles.

Answer

Global Find

Answer

ACC (Application Command Center)

Answer

Threat Log viewer

Question 5

You need to ensure that files uploaded to a specific server are scanned by WildFire. Which setting ensures this?

Accepted Answer

Enable 'Upload' in the File Blocking profile for the specific file types.. WildFire forwarding is configured within the File Blocking profile, which is then attached to the security policy rule.

Answer

Enable 'WildFire' in the Antivirus profile.

Answer

Add the server's IP to the 'WildFire Analysis' whitelist.

Answer

Configure a 'Log Forwarding' profile for WildFire.

Question 6

Which THREE settings are required in a File Blocking profile to ensure that all executable files are blocked and submitted to WildFire?

Accepted Answer

Select the 'exe' file type.. To block and submit files, the action must be set correctly for the specific file type.

Answer

Enable 'Alert' as the only action.

Answer

Disable 'Session Log' in the Security Profile.

Question 7

Which THREE actions can be taken in a Vulnerability Protection profile?

Accepted Answer

Reset-Both. Vulnerability protection profiles allow for flexible handling of detected threats based on severity or type.

Answer

Block

Answer

Allow

Answer

Monitor

Question 8

What is the primary function of the 'DNS Sinkhole' feature in a DNS Security profile?

Accepted Answer

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
