NetSec-Analyst Practice Test 4 — 10 Questions

Question 1

An administrator suspects that a specific App-ID is not correctly identifying traffic. Which log column should they examine to confirm the application match?

Accepted Answer

Application. The 'Application' column in the Traffic log explicitly displays what the firewall identified as the application for the session.

Answer

Category

Answer

Policy

Answer

Service

Question 2

What is the purpose of the 'Zone' in a Palo Alto Networks firewall?

Accepted Answer

To group interfaces for security enforcement. Zones are logical groupings of interfaces that allow for granular security policy enforcement.

Answer

To identify applications

Answer

To route traffic

Answer

To group IP addresses

Question 3

An organization has a strict requirement that all web traffic must be inspected. Which policy is required in addition to the Security policy to achieve this?

Accepted Answer

Decryption Policy. Decryption policy is necessary for the firewall to see inside SSL/TLS traffic.

Answer

Device Policy

Answer

NAT Policy

Answer

QoS Policy

Question 4

Which object type would you use to define a range of IP addresses (e.g., 10.1.1.1 to 10.1.1.50) in PAN-OS?

Accepted Answer

IP Range. An IP Range object is specifically designed to cover a non-CIDR block range of IP addresses.

Answer

IP Netmask

Answer

FQDN

Answer

Address Group

Question 5

A network security administrator is configuring a firewall to send alerts to an external SIEM when a critical threat is detected. The administrator wants to ensure that the alerts include the source and destination IP addresses, threat name, and severity. Which configuration step is necessary to achieve this?

Accepted Answer

Create a Log Forwarding profile that matches the threat log and specifies the SIEM as a syslog server, then attach it to the security policy.. To forward threat logs to an external SIEM with specific fields, a Log Forwarding profile must be created and attached to the security policy. The profile matches threat logs and specifies the syslog server (SIEM) as the destination. This ensures that when a threat is detected, the log is sent with the configured details. Other options either do not forward logs or forward the wrong log type.

Answer

Enable 'Log at Session Start' and 'Log at Session End' in the security policy to capture all traffic and forward to SIEM.

Answer

Set up an Email profile to send alerts to the SIEM's email address and include threat details in the email format.

Answer

Configure a syslog server in the Device > Server Profiles > Syslog section and enable threat logging globally.

Question 6

A network security analyst is troubleshooting a site-to-site VPN tunnel that is showing as 'up' but no traffic is passing through it. The analyst wants to verify if the firewall is encrypting and decrypting packets correctly. Which tool should the analyst use to capture and examine the packets?

Accepted Answer

Use the packet capture feature with a filter for the VPN tunnel interface to inspect encrypted and decrypted packets.. When a VPN tunnel is up but no traffic passes, the analyst must verify that packets are being encrypted and decrypted. Packet capture on the tunnel interface allows examination of both the encrypted outer packets and the decrypted inner packets. This confirms whether the firewall is processing traffic correctly. Other options like checking status or logs do not provide direct evidence of packet flow.

Answer

Review the system logs for IKE negotiation errors.

Answer

Check the VPN status in the web interface to see if the tunnel is up.

Answer

Run a traceroute from a host behind the firewall to a remote host to see where packets are dropped.

Question 7

When managing objects in SCM, which actions can be performed on tags? (Choose TWO)

Accepted Answer

Assigning a color. Option A (Assigning a color) is correct because Palo Alto Networks SCM (Strata Cloud Manager) allows administrators to assign a color to a tag, which serves as a visual label for quick identification and filtering of tagged objects. Option D (Applying to objects for organization) is correct because tags are metadata labels that can be attached to objects such as addresses, address groups, and policies to categorize, group, and organize them logically within SCM. Options B and C are incorrect because IP ranges and port protocols are attributes of address objects and service objects respectively, not of tags. Option E is incorrect because a security policy is a separate rule construct that can reference tags, but tags themselves do not create security policies.

Answer

Defining an IP range

Answer

Defining a port protocol

Answer

Creating a security policy

Question 8

A security analyst is tasked with reviewing the firewall's logs to identify potential security incidents. The analyst needs to ensure that logs are being forwarded to an external SIEM for long-term retention and analysis. Which TWO actions must the analyst verify are configured correctly on the firewall? (Choose two.)

Accepted Answer

A Log Forwarding profile is applied to security policy rules.. To forward logs to an external SIEM, the firewall must have a syslog server profile that defines the SIEM's address and port, and a Log Forwarding profile that references that syslog profile and is applied to security policy rules. These two components ensure logs are generated and sent to the SIEM. Other options, such as management gateway, Threat Prevention license, or local logging, do not enable external forwarding.

Answer

The firewall has a valid Threat Prevention license.

Answer

The firewall's management interface has a default gateway.

Answer

The security policy rules have logging enabled at session end.

Question 9

Which elements are required when creating a new custom Service Object? (Choose THREE)

Accepted Answer

Protocol. When creating a custom Service Object, the Protocol (A) is required because the firewall must know which IP protocol (e.g., TCP, UDP, ICMP) the service uses to match traffic correctly. The Port (C) is required because a service object defines the destination port (or port range) that the protocol operates on, such as TCP/443. The Name (D) is required because every service object must have a unique identifier used to reference it in security policy rules. Tag (B) is optional metadata used for grouping or filtering objects and is not mandatory for creation. Description (E) is also optional documentation and is not required for the object to function.

Answer

Tag

Answer

Description

Question 10

Where do you go in SCM to manage all your network objects in one location?

Accepted Answer

Objects tab. The 'Objects' tab is the centralized location for creating and managing all configuration objects.

Answer

Policies tab

Answer

Monitor tab

Answer

Device Settings tab
