NEW QUESTION # 66
What are two potential causes when a secondary public circuit has been added to the branch site, but the Prisma SD-WAN tunnel is not forming to the data center? (Choose two.)
Answer: B,D
Explanation:
Comprehensive and Detailed Explanation
In Prisma SD-WAN (formerly CloudGenix), the establishment of Secure Fabric (VPN) tunnels is automated but relies heavily on the correct definition of the Network Context for each interface. If a tunnel fails to form on a newly added s2econdary circuit, it is typically due to a misconfiguration in how the interface is defined in the ION portal.
1. Interface Scope (Statement D):
The Scope setting on an interface determines its function in the network topology.
Global Scope: This defines the interface as a WAN-facing port. The ION device will only attempt to build VPN tunnels (overlay) on interfaces configured with Global scope.
Local Scope: This defines the interface as a LAN-facing port (for users, switches, or APs). If the administrator mistakenly sets the scope to "Local" for the new internet line, the ION treats it as a private LAN segment and will not initiate any tunnel negotiation or WAN signaling on that port.
2. Interface Role/Circuit Category (Statement A):
Prisma SD-WAN uses Circuit Categories (often referred to as Interface Roles in general networking terms, or specifically "Circuit Category" in the ION UI) to determine peering logic.
To form a tunnel over a public internet link to a Data Center, the circuit attached to the interface must be categorized as "Internet".
The controller uses this category to match compatible endpoints. It knows that a "Private WAN" (MPLS) link cannot directly tunnel to an "Internet" link without a gateway. If the new circuit is not correctly selected/categorized as "Internet" (e.g., left undefined or set to a different category), the system will not attempt to build the standard IPSec overlay to the Data Center's public IP address.
NEW QUESTION # 67
When identifying devices for IoT classification purposes, which two methods does Prisma SD-WAN use to discover devices that are not directly connected to the branch ION? (Choose two.)
Answer: B,C
Explanation:
Comprehensive and Detailed Explanation
Prisma SD-WAN (formerly CloudGenix) integrates with Palo Alto Networks IoT Security to provide comprehensive visibility into all devices at a branch, including those that are not directly connected to the ION device. While the ION automatically detects and classifies devices connected directly to its interfaces via traffic inspection (DPI), DHCP, and ARP analysis, gaining visibility into off-branch devices (devices connected to downstream switches or access points) requires additional discovery mechanisms that can query the network infrastructure or ingest its logs.
1. SNMP (Simple Network Management Protocol): This is the primary active discovery method for off-branch devices. The Prisma SD-WAN ION device acts as a sensor that actively polls local network switches and wireless controllers using SNMP. By querying the ARP tables and MAC address tables (Bridge MIBs) of these intermediate network devices, the ION can identify endpoints that are connected to the switch ports, even if those endpoints are not currently sending traffic through the ION. This allows the system to map the topology and discover silent or lateral-traffic-only devices.
2. Syslog: In conjunction with SNMP, the IoT Security solution can utilize Syslog messages to discover and profile devices. Network infrastructure devices (like switches and WLAN controllers) can be configured to send Syslog messages to the collection point (which enables the IoT Security service) whenever a device connects or disconnects (e.g., port up/down events, DHCP snooping logs, or 802.1x authentication logs). These logs provide real-time data about device presence and identity (MAC/IP mappings) for devices that are not directly adjacent to the ION, ensuring 100% visibility across the branch network segments. LLDP (A) and CDP (B) are typically Link Layer discovery protocols used for discovering directly connected neighbors and do not propagate beyond the immediate link, making them unsuitable for discovering devices multiple hops away or behind a switch.
NEW QUESTION # 68
An administrator has configured a Path Policy for "ERP_Traffic". The policy allows two public internet links, "ISP-A" and "ISP-B", both marked as "Active". The Path Quality Profile (SLA) requires a latency of less than 150ms. Currently, both ISP-A and ISP-B have a latency of 40ms, well within the SLA.
How does the Prisma SD-WAN ION determine which link to use for a new flow of "ERP_Traffic" when both active paths meet the SLA requirements?
Answer: C
Explanation:
Comprehensive and Detailed Explanation
Prisma SD-WAN utilizes a sophisticated decision engine for Application-Based Path Selection that goes beyond simple failover. When configuring a Path Policy, the administrator defines "Active" paths and a "Path Quality Profile" (SLA).
SLA Compliance (The Filter): First, the system filters the available paths based on the Path Quality Profile. In this scenario, both ISP-A and ISP-B have 40ms latency against a 150ms threshold. Both are "green" or compliant paths.
Selection Criteria (The Tie-Breaker): When multiple paths are configured as "Active" and all meet the performance SLA, the ION device aims to optimize the overall user experience and network utilization. The default behavior for load balancing across healthy, compliant active paths is to select the path with the highest available bandwidth capacity.
By steering new flows to the link with the most "headroom" (available Mbps), the system prevents the saturation of a smaller link (e.g., a 20Mbps DSL line) while a larger link (e.g., 1Gbps Fiber) sits underutilized. This maximizes the aggregate throughput for the site. While latency is the qualifier, bandwidth availability is often the selector for compliant paths. Note that if the application was defined as "Real-Time" and configured for packet duplication, behavior would differ, but for standard traffic, capacity-based distribution is the standard active/active logic.
NEW QUESTION # 69
When configuring SASE connectivity with easy onboarding at a branch, which two options must be selected?
(Choose two.)
Answer: A,B
Explanation:
Prisma SD-WAN simplifies the integration with Prisma Access through a feature known as "CloudBlades," specifically the Prisma Access for Networks CloudBlade. The "easy onboarding" workflow is designed to automate the complex task of establishing secure tunnels between Branch ION devices and the SASE security processing nodes (SPNs).
When an administrator initiates this process, the system abstracts the manual configuration of IKE and IPSec parameters. Instead of manually defining an IPSec Crypto Profile or an IKE Profile (which are automatically handled by the CloudBlade orchestration), the user must specify where the traffic is going and which physical resources will handle the connection. The Prisma Access Primary Location (Option B) is a mandatory selection because it determines the geographical region and specific compute instance within the Prisma Access cloud that will serve as the primary security gateway for that branch.
Furthermore, the IPSec Termination Node (Option D) must be selected to define the specific endpoint within the Prisma Access infrastructure where the ION device's tunnels will terminate. This selection ensures that the Controller can properly orchestrate the site-to-site VPN tunnels, ensuring that the branch traffic is correctly routed to the SASE fabric for security inspection. By selecting these two options, the CloudBlade can automatically negotiate the rest of the tunnel parameters, significantly reducing the potential for human error and accelerating the deployment of a Secure Access Service Edge (SASE) architecture across multiple branch locations.
NEW QUESTION # 70
Return traffic for an application from the branch is being dropped on the branch ION. Application traffic arrives via SD-WAN internet overlay at the branch, and path policy for the application at the branch has the following settings:
Active = MPLS Overlay
Backup = Prisma Access on internet
Which branch configuration is the probable cause of this behavior?
Answer: D
Explanation:
In Prisma SD-WAN, path selection and traffic symmetry are governed by the Path Policy and the available physical/virtual circuits at a site. The scenario describes a situation where return traffic is dropped on the branch ION after arriving via an Internet overlay. To understand why, we must analyze the "Active" and
"Backup" paths defined in the policy.
The policy specifies Active = MPLS Overlay and Backup = Prisma Access on internet. In a healthy environment, the ION device expects to send and receive traffic based on these defined paths. If the site actually has two internet circuits and no MPLS circuit (Option C), a critical mismatch occurs. Because there is no MPLS circuit available to satisfy the "Active" path, the device will fall back to the "Backup" path for initiated traffic.
However, the core issue here relates to how Prisma SD-WAN handles asymmetric routing and session state.
If traffic arrives at the branch via an "Internet Overlay" path that is not explicitly defined or allowed as a valid path for that specific application in the Path Policy, the ION device's flow integrity checks may drop the packets. Specifically, if the ION is configured with only Internet circuits but the policy is looking for an MPLS overlay that doesn't exist, the device may fail to correctly associate the return packets with the session state if the paths are perceived as "unbound" or "invalid" per the policy. This behavior is a security feature designed to ensure that traffic only traverses paths that meet the administrator's defined performance and security criteria. Without an MPLS circuit present, the policy cannot be fully realized, leading to potential drops for traffic arriving on paths not intended for that specific application flow.
