NetSec-Analyst Practice Test 4 — 25 Questions

Question 1

An administrator is creating a new Service Group that will contain several Service Objects for different applications. They want to ensure that the Service Group can be used in a Security Policy to allow traffic for all the services. However, they also want to minimize the number of objects they need to manage. Which of the following is a valid consideration when creating a Service Group?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

A Service Group can contain other Service Groups, allowing hierarchical grouping.. Service Groups can contain other Service Groups, allowing for nested groupings. This hierarchical structure helps organize services and reduce the number of objects referenced in policies. The other options are incorrect: Service Groups can contain mixed protocols, do not require port ranges, and can be modified after being referenced.

Answer

A Service Group can only contain Service Objects of the same protocol (TCP or UDP).

Answer

A Service Group can only be used in a Security Policy if it contains at least one Service Object with a port range.

Answer

A Service Group cannot be modified after it is referenced in a Security Policy.

Question 2

In a scenario where you use an Application Object in a Security Policy, how does the firewall identify the traffic?

Accepted Answer

By App-ID inspection. The firewall uses App-ID, which performs deep packet inspection to identify the application, regardless of the port being used.

Answer

By the DNS request

Answer

By the source IP

Answer

By the destination port

Question 3

You want to color-code objects in Strata Cloud Manager to improve visibility. Which feature do you use?

Accepted Answer

Tags. Tags are used to provide metadata, including colors, to objects for better organization and visual identification.

Answer

Device Groups

Answer

Descriptions

Answer

Object Filtering

Question 4

A NetSec-Analyst is configuring a Dynamic Address Group (DAG) that should include all servers tagged as 'Web'. The analyst notices that some servers with the 'Web' tag are not appearing in the DAG. The tags are applied via a VM monitoring agent. What is the most likely cause?

Accepted Answer

The DAG filter is case-sensitive and the tag is 'web' instead of 'Web'.. Dynamic Address Group filters match tags or metadata exactly, including case. If the tag is registered as 'web' but the filter expects 'Web', those servers will not be included. Checking tag casing and consistency is the first troubleshooting step.

Answer

The VM monitoring agent is not licensed for dynamic address groups.

Answer

The servers are in a different security zone than the DAG.

Answer

The DAG filter requires an IP address instead of a tag.

Question 5

If an administrator wants to ensure that a specific server can only be accessed from a specific internal subnet, where is this best configured?

Accepted Answer

Security Policy. The Security Policy is the correct place to enforce source-to-destination-to-application access control.

Answer

Decryption Policy

Answer

NAT Policy

Answer

QoS Policy

Question 6

A network security analyst is reviewing the firewall's dashboard and notices that the 'Threat Prevention' license is about to expire in 30 days. The analyst needs to verify the current license status and expiry date for all subscriptions on the firewall. Which action should the analyst take?

Accepted Answer

Navigate to Device > Licenses and view the license table.. The Device > Licenses page is the authoritative place to check all installed licenses, their status, and expiration dates. It provides a comprehensive list and is the recommended method for verifying subscription details. Other options either provide incomplete information or are less direct. The analyst should use this page to confirm the Threat Prevention license status and plan renewal.

Answer

View the 'Subscription Status' widget on the Dashboard.

Answer

Check the System Logs for license-related events.

Answer

Run the 'show license' command in the CLI.

Question 7

An administrator needs to create a new Security Policy rule that allows HTTP and HTTPS traffic from the internal network to a specific external web server. The internal network is already defined as an Address object, and the external server is defined as an FQDN object. Which additional object is required to complete the rule?

Accepted Answer

A Service object for TCP ports 80 and 443. To complete the Security Policy rule, the administrator must specify the service that matches HTTP and HTTPS. A Service object defining TCP ports 80 and 443 is required. The source and destination are already covered by the existing Address and FQDN objects. Other object types do not provide the necessary port-based service definition.

Answer

A Dynamic Address Group for the external server

Answer

An Application object for web-browsing

Answer

An Address Group containing the internal network and external server

Question 8

When deploying a new firewall, why is it critical to synchronize the clock with an NTP server?

Accepted Answer

To ensure accurate log timestamps and SSL certificate validation.. Accurate system time is essential for correct logging, certificate validation, and threat detection timing.

Answer

To ensure the license server accepts the activation.

Answer

To prevent unauthorized access to the web interface.

Answer

To allow for faster software downloads.

Question 9

Which TWO ways can an administrator verify that a security subscription is active?

Accepted Answer

Via the Device > Licenses GUI page.. Option A is correct because the Device > Licenses GUI page in PAN-OS displays the installed licenses and their status, allowing an administrator to confirm whether the security subscription is active. Option E is correct because the CLI command 'show system license' outputs the current license state, including subscription validity and expiration dates. Option B is incorrect because the physical serial number label only identifies the firewall hardware and does not indicate license or subscription status. Option C is incorrect because Traffic Logs record session activity, not licensing state. Option D is incorrect because pinging the license server only tests network reachability and does not verify that the subscription itself is active.

Answer

By reviewing the firewall's physical serial number label.

Answer

By checking the Traffic Logs.

Answer

By pinging the license server.

Question 10

Why might an Address Object using an IP Netmask return a validation error even if the IP is valid?

Accepted Answer

The IP address bits outside the mask are not zeroed out. The IP address must match the specified netmask (e.g., 10.1.1.5/24 is invalid because the host bits are set).

Answer

The netmask is too small

Answer

The address is in a private range

Answer

The address is already in use

Question 11

An administrator attempts to delete an Address Object that is referenced by a security policy. What will happen?

Accepted Answer

The deletion is blocked, and the administrator must remove the object from all policies first.. Strata Cloud Manager blocks the deletion of an object that is referenced in a security policy. The administrator must first remove the object from all policies, then delete it. This referential integrity check prevents accidental policy misconfigurations and ensures that policies always reference valid objects.

Answer

The object is deleted, and the policy rule automatically removes the reference.

Answer

The object is moved to a trash folder, and the policy continues to function using a cached copy.

Answer

The object is deleted, but the policy rule becomes invalid and stops matching traffic.

Question 12

A security analyst is reviewing a firewall policy that uses Security Profiles to protect against known threats. The analyst notices that a file download was allowed and later found to contain a malicious payload that should have been blocked by the antivirus profile. Which action should the analyst take to ensure the antivirus profile inspects the file content in real time?

Accepted Answer

Verify that the antivirus profile is attached to the security policy that allows the file download.. Security Profiles are only enforced when they are attached to a security policy that matches the traffic. Without the antivirus profile linked to the allowing rule, file downloads are not scanned, and malicious content can be delivered. The analyst must confirm the profile is applied to the correct policy, as other actions like changing the rule action or inspection mode do not address the missing profile attachment.

Answer

Configure the antivirus profile to use 'Stream-based' inspection instead of 'Buffer-based'.

Answer

Enable the 'Forward' action in the antivirus profile.

Answer

Change the security policy action from allow to deny.

Question 13

A security analyst is reviewing a firewall policy that includes a rule allowing traffic from the 'Trust' zone to the 'Untrust' zone with the Application ID 'any'. The analyst notices that the rule has no Security Profiles attached. The analyst wants to enforce a policy that all allowed traffic must be inspected for threats, but also wants to minimize the impact on legitimate traffic. What should the analyst do?

Accepted Answer

Attach a Security Profile Group to the existing rule with 'any' Application ID.. Attaching a Security Profile Group to the existing rule enforces threat inspection on all allowed traffic without changing the allowed applications. This minimizes impact because legitimate traffic continues to be allowed, but is now inspected. The other options either disrupt traffic or do not enforce inspection.

Answer

Create a new rule above the existing rule that denies all traffic without profiles.

Answer

Enable 'Log at Session End' on the rule and review logs to identify applications, then create specific rules.

Answer

Change the Application ID from 'any' to specific applications and attach a Security Profile Group.

Question 14

A network security analyst is troubleshooting an issue where a user cannot access a website. The analyst suspects that the traffic is being denied by a security policy. Which CLI command should the analyst use to simulate the flow and see which security policy rule is matching?

Accepted Answer

test security-policy-match. The 'test security-policy-match' command is designed to simulate a flow and determine which security policy rule matches and what action is taken. By providing the source, destination, user, application, and service, the analyst can see the exact rule and whether it allows or denies the traffic. This directly answers why the user cannot access the website, as it will show if a deny rule is matching or if no rule matches and the default deny applies.

Answer

show running security-policy

Answer

debug dataplane packet-diag set filter match source <user-IP>

Answer

show session all filter source <user-IP>

Question 15

What is the purpose of the 'Service' field in a Security Policy?

Accepted Answer

To define the port. The 'Service' field specifies the TCP/UDP ports to be allowed or denied, though App-ID is preferred.

Answer

To define the NAT rule

Answer

To define the application

Answer

To define the user

Question 16

A NetSec-Analyst is creating a new Address Object for a subnet that will be used in multiple Security Policy rules. The analyst wants to ensure that if the subnet changes in the future, the change is reflected everywhere the object is used. What is the most efficient way to achieve this?

Accepted Answer

Create a single Address Object and reference it in all relevant rules.. Reusing a single Address Object across multiple rules ensures that any change to the object is automatically reflected in all rules. This centralizes management and reduces the chance of misconfiguration. Other options either duplicate effort or add unnecessary layers.

Answer

Create a separate Address Object for each rule to avoid dependency.

Answer

Create an Address Group containing the subnet and reference the group in rules.

Answer

Use a static IP address directly in each rule instead of an object.

Question 17

If an administrator creates an object in a local firewall that is also managed by SCM, what happens during the next push?

Accepted Answer

The object will be overwritten by the SCM configuration. SCM push operations typically overwrite local configuration changes to ensure that the centrally managed policy remains the source of truth.

Answer

The push will fail

Answer

The object is preserved

Answer

The object is merged

Question 18

How can an administrator quickly determine if the firewall is experiencing high CPU usage?

Accepted Answer

View the Dashboard System Resources widget.. The Dashboard provides a 'System Resources' widget that shows real-time CPU and memory usage statistics.

Answer

Check the Traffic Logs.

Answer

Use the 'show interface' CLI command.

Answer

Monitor the Threat logs.

Question 19

Which log would display an event regarding an administrator logging into the WebUI?

Accepted Answer

System Log. Configuration and administrative access logs are stored in the System log.

Answer

Threat Log

Answer

Config Log

Answer

Traffic Log

Question 20

A security analyst is troubleshooting a Dynamic Address Group (DAG) that is not populating with expected IP addresses. The DAG is configured with the filter 'tag.production' and is intended to include all servers tagged with 'production'. The analyst verifies that several servers have the 'production' tag applied. What is the most likely cause for the DAG not populating?

Accepted Answer

The servers' IP addresses have not been registered with the tags through a dynamic address group registration process.. Dynamic Address Groups populate based on IP-to-tag mappings registered through external processes. Applying a tag to a server in a management interface does not automatically register its IP address with that tag. The most likely cause is that the IP addresses have not been registered with the 'production' tag via a supported mechanism, such as a User-ID agent or API. This is a common oversight in DAG configuration.

Answer

The DAG must be manually refreshed by restarting the management server.

Answer

The DAG filter syntax must use 'and' instead of a period to combine tag and value.

Answer

The tag 'production' must be defined as a static address object before it can be used in a DAG filter.
