Palo Alto Networks PSE-Strata-Pro-24 Palo Alto Networks Systems Engineer Professional - Hardware Firewall Exam Practice Test

Answer : A

To configure GlobalProtect to authenticate users from multiple SAML identity providers (IdPs), the correct approach involves creating multiple authentication profiles, one for each IdP. Here's the analysis of each option:

Option A: GlobalProtect with multiple authentication profiles for each SAML IdP

GlobalProtect allows configuring multiple SAML authentication profiles, each corresponding to a specific IdP.

These profiles are associated with the GlobalProtect portal or gateway. When users attempt to authenticate, they can be directed to the appropriate IdP based on their domain or other attributes.

This is the correct approach to enable authentication for users from multiple IdPs.

Option B: Multiple authentication mode Cloud Identity Engine authentication profile for use on the GlobalProtect portals and gateways

The Cloud Identity Engine (CIE) can synchronize identities from multiple directories, but it does not directly support multiple SAML IdPs for a shared GlobalProtect setup.

This option is not applicable.

Option C: Authentication sequence that has multiple authentication profiles using different authentication methods

Authentication sequences allow multiple authentication methods (e.g., LDAP, RADIUS, SAML) to be tried in sequence for the same user, but they are not designed for handling multiple SAML IdPs.

This option is not appropriate for the scenario.

Option D: Multiple Cloud Identity Engine tenants for each business unit

Deploying multiple CIE tenants for each business unit adds unnecessary complexity and is not required for configuring GlobalProtect to authenticate users to multiple SAML IdPs.

This option is not appropriate.

Answer : B

Advanced WildFire is Palo Alto Networks' cloud-based malware analysis and prevention solution. It determines whether files are malicious by executing them in a sandbox environment and observing their behavior. To address the customer's concern about the file categorization, the systems engineer must provide evidence of the file's behavior. Here's the analysis of each option:

Option A: Review the threat logs for information to provide to the customer

Threat logs can provide a summary of events and verdicts for malicious files, but they do not include the detailed behavior analysis needed to convince the customer.

While reviewing the logs is helpful as a preliminary step, it does not provide the level of proof the customer needs.

This option is not sufficient on its own.

Option B: Use the WildFire Analysis Report in the log to show the customer the malicious actions the file took when it was detonated

WildFire generates an analysis report that includes details about the file's behavior during detonation in the sandbox, such as network activity, file modifications, process executions, and any indicators of compromise (IoCs).

This report provides concrete evidence to demonstrate why the file was flagged as malicious. It is the most accurate way to assure the customer that WildFire's decision was based on observed malicious actions.

This is the best option.

Option C: Open a TAG ticket for the customer and allow support engineers to determine the appropriate action

While opening a support ticket is a valid action for further analysis or appeal, it is not a direct way to assure the customer of the current WildFire verdict.

This option does not directly address the customer's request for immediate proof.

This option is not ideal.

Option D: Do nothing because the customer will realize Advanced WildFire is right

This approach is dismissive of the customer's concerns and does not provide any evidence to support WildFire's decision.

This option is inappropriate.

Answer : A, C

Zero Trust principles revolve around minimizing trust in the network and verifying every interaction. To adopt Zero Trust, customers should start by gaining visibility and understanding the network and its transactions.

A . Understand which users, devices, infrastructure, applications, data, and services are part of the network or have access to it.

The first step in adopting Zero Trust is understanding the full scope of the network. Identifying users, devices, applications, and data is critical for building a comprehensive security strategy.

C . Map the transactions between users, applications, and data, then verify and inspect those transactions.

After identifying all assets, the next step is to map interactions and enforce verification and inspection of these transactions to ensure security.

Why Other Options Are Incorrect

B: Enabling CDSS subscriptions is important for protection but comes after foundational Zero Trust principles are established.

D: Implementing VM-Series NGFWs is part of enforcing Zero Trust, but it is not the first step. Visibility and understanding come first.

Answer : B

Segregating a network into unique BGP environments requires the ability to configure separate eBGP autonomous systems (AS) within the NGFW. Palo Alto Networks firewalls support advanced BGP features, including the ability to create and manage multiple autonomous systems.

Why 'It can be addressed by creating multiple eBGP autonomous systems' (Correct Answer B)?

PAN-OS supports the configuration of multiple eBGP AS environments. By creating unique eBGP AS numbers for different parts of the network, traffic can be segregated and routed separately. This feature is commonly used in multi-tenant environments or networks requiring logical separation for administrative or policy reasons.

Each eBGP AS can maintain its own routing policies, neighbors, and traffic segmentation.

This approach allows the NGFW to address the customer's need for segregated internal BGP environments.

Why not 'It cannot be addressed because PAN-OS does not support it' (Option A)?

This statement is incorrect because PAN-OS fully supports BGP, including eBGP, iBGP, and features like route reflectors, confederations, and autonomous systems.

Why not 'It can be addressed with BGP confederations' (Option C)?

While BGP confederations can logically group AS numbers within a single AS, they are generally used to simplify iBGP designs in very large-scale networks. They are not commonly used for segregating internal environments and are not required for the described use case.

Why not 'It cannot be addressed because BGP must be fully meshed internally to work' (Option D)?

Full mesh iBGP is only required in environments without route reflectors. The described scenario does not mention the need for iBGP full mesh; instead, it focuses on segregated environments, which can be achieved with eBGP.

Answer : C, D

In this scenario, the company does not use on-premises Active Directory and manages devices with Entra ID and Jamf, which implies a cloud-native and modern management setup. Below is the evaluation of each option:

Option A: Captive portal

Captive portal is typically used in environments where identity mapping is needed for unmanaged devices or guest users. It provides a mechanism for users to authenticate themselves through a web interface.

However, in this case, the company is managing devices using Entra ID and Jamf, which means identity information can already be centralized through other means. Captive portal is not an ideal solution here.

This option is not appropriate.

Option B: User-ID agents configured for WMI client probing

WMI (Windows Management Instrumentation) client probing is a mechanism used to map IP addresses to usernames in a Windows environment. This approach is specific to on-premises Active Directory deployments and requires direct communication with Windows endpoints.

Since the company does not have an on-premises AD and is using Entra ID and Jamf, this method is not applicable.

This option is not appropriate.

Option C: GlobalProtect with an internal gateway deployment

GlobalProtect is Palo Alto Networks' VPN solution, which allows for secure remote access. It also supports identity-based mapping when deployed with internal gateways.

In this case, GlobalProtect with an internal gateway can serve as a mechanism to provide user and device visibility based on the managed devices connecting through the gateway.

This option is appropriate.

Option D: Cloud Identity Engine synchronized with Entra ID

The Cloud Identity Engine provides a cloud-based approach to synchronize identity information from identity providers like Entra ID (formerly Azure AD).

In a cloud-native environment with Entra ID and Jamf, the Cloud Identity Engine is a natural fit as it integrates seamlessly to provide identity visibility for applications and data.

This option is appropriate.

Device-ID is a feature in Palo Alto Networks firewalls that identifies devices based on their unique attributes (e.g., MAC addresses, device type, operating system). Device-ID can be used in several policy types to provide granular control. Here's how it applies to each option:

Option A: Security

Device-ID can be used in Security policies to enforce rules based on the device type or identity. For example, you can create policies that allow or block traffic for specific device types (e.g., IoT devices).

This is correct.

Option B: Decryption

Device-ID cannot be used in decryption policies. Decryption policies are based on traffic types, certificates, and other SSL/TLS attributes, not device attributes.

This is incorrect.

Option C: Policy-based forwarding (PBF)

Device-ID can be used in PBF policies to control the forwarding of traffic based on the identified device. For example, you can route traffic from certain device types through specific ISPs or VPN tunnels.

This is correct.

Option D: SD-WAN

SD-WAN policies use metrics such as path quality (e.g., latency, jitter) and application information for traffic steering. Device-ID is not a criterion used in SD-WAN policies.

This is incorrect.

Option E: Quality of Service (QoS)

Device-ID can be used in QoS policies to apply traffic shaping or bandwidth control for specific devices. For example, you can prioritize or limit bandwidth for traffic originating from IoT devices or specific endpoints.

This is correct.

When sizing a Palo Alto Networks NGFW appliance, it's crucial to consider variables that affect its performance and capacity. These include the network's traffic characteristics, application requirements, and expected workloads. Below is the analysis of each option:

Option A: Connections per second

Connections per second (CPS) is a critical metric for determining how many new sessions the firewall can handle per second. High CPS requirements are common in environments with high traffic turnover, such as web servers or applications with frequent session terminations and creations.

This is an important sizing variable.

Option B: Max sessions

Max sessions represent the total number of concurrent sessions the firewall can support. For environments with a large number of users or devices, this metric is critical to prevent session exhaustion.

This is an important sizing variable.

Option C: Packet replication

Packet replication is used in certain configurations, such as TAP mode or port mirroring for traffic inspection. While it impacts performance, it is not a primary variable for firewall sizing as it is a specific use case.

This is not a key variable for sizing.

Option D: App-ID firewall throughput

App-ID throughput measures the firewall's ability to inspect traffic and apply policies based on application signatures. It directly impacts the performance of traffic inspection under real-world conditions.

This is an important sizing variable.

Option E: Telemetry enabled

While telemetry provides data for monitoring and analysis, enabling it does not significantly impact the sizing of the firewall. It is not a core variable for determining firewall performance or capacity.

This is not a key variable for sizing.
