Palo Alto Networks Certified Network Security Consultant PCNSC Exam Questions

Answer : A

To start using Device-ID to obtain policy rule recommendations, the customer needs to purchase:

A . a Cortex Data Lake license

The Cortex Data Lake is a cloud-based logging service that aggregates data from all Palo Alto Networks products and services. Device-ID uses this data to provide insights and recommendations for policy rules based on the identities of devices on the network.

Answer : A, B, E

To set up tunnel monitoring on an IPsec VPN tunnel between two offices, the following steps are needed:

A . Create a monitoring profile: This profile defines the criteria for monitoring, such as the IP address to ping and the failure condition.

B . Add an IP address to each tunnel interface: Tunnel monitoring requires an IP address on each tunnel interface to send and receive monitoring pings.

E . Enable tunnel monitoring on each IPsec tunnel: This step activates the monitoring profile on the IPsec tunnel, ensuring that the tunnel is actively monitored and can trigger alerts or failover mechanisms if the tunnel goes down.

These steps ensure that the tunnel is properly monitored, allowing for proactive detection and response to connectivity issues.

Answer : C

The security policy rule shown in the image is configured to permit traffic from a source zone LAN-User-Zone to a destination zone Server-Zone. The applications allowed include tftp, ssl, and web-browsing, and the action is allow. According to Iron Skillet day one configurations, which provide best practice security profiles for immediate deployment, the relevant security profile group used to secure internal traffic like this is the Internal profile group.

Iron Skillet provides predefined configuration templates including security profile groups like Internal, External, and others to quickly secure traffic according to typical deployment scenarios.

Answer : B, C, D

The interface deployments that support the Aggregate Ethernet (AE) Active configuration are:

B . LACP in Layer 3: Link Aggregation Control Protocol (LACP) can be used in Layer 3 interfaces to bundle multiple physical interfaces into a single logical interface for redundancy and increased bandwidth.

C . LACP in Layer 2: LACP can be used in Layer 2 interfaces to aggregate multiple Ethernet interfaces, enhancing throughput and providing failover capabilities within a Layer 2 network.

D . LACP in Virtual Wire: LACP can also be configured in Virtual Wire mode, which allows the firewall to aggregate interfaces while operating in a transparent mode, bridging traffic between interfaces without routing.

These configurations leverage LACP to improve network performance and reliability by combining multiple physical links into a single logical link.

Answer : B, D

Disabling App-IDs as part of a content update can be valid in the following circumstances:

B . When you want to immediately benefit from the latest threat prevention: Disabling certain App-IDs can help ensure that the latest threat prevention measures are applied without waiting for the App-IDs to be fully tested in a specific environment. This can be crucial in quickly addressing emerging threats.

D . When an organization operates a mission-critical network and has zero tolerance for downtime: In such environments, administrators might temporarily disable new or modified App-IDs to avoid potential disruptions caused by unverified or untested App-IDs. This ensures that the network remains stable and functional while the new App-IDs are evaluated in a controlled manner.

Answer : C

To verify whether all SFP, SFP+, or QSFP modules are installed in a firewall, you should use the following CLI command:

C . show system state filter sys.s-phy*

This command provides detailed information about the physical state of the system, including the status of SFP, SFP+, and QSFP modules installed in the firewall.
