42. Frage
When defining a Path Quality Profile (SLA) for a "Transactional" application group (e.g., Citrix, Oracle), the administrator sets the "Packet Loss" threshold to 1%.
What happens to the traffic for this application if all active paths currently exceed this 1% loss threshold?
Antwort: C
Begründung:
Comprehensive and Detailed Explanation
This behavior describes the "Best Available Path" logic inherent in Prisma SD-WAN's availability design.
* SLA Thresholds: Path Quality Profiles act as filters to identify compliant paths.
* Total Violation: If all configured "Active" paths violate the SLA (e.g., Path A has 2% loss, Path B has
5% loss, and the threshold is 1%), the system does not drop the traffic (Option A) because maintaining connectivity is prioritized over perfect quality.
* Selection Logic: The system enters a fallback state where it compares the available active paths and selects the "Least Bad" one-the path that is closest to meeting the SLA (in this case, Path A with 2% loss).
* Backup Paths: Traffic would only move to a Backup path (Option D) if the policy explicitly configures the backup path to engage upon SLA violation of the active set. However, strictly speaking, if only active paths are considered and all fail, it picks the best of the active group rather than blackholing the traffic.
43. Frage
A network engineer is troubleshooting a "Voice Quality" issue. They suspect that the DSCP markings are being stripped or altered by the ISP.
Which tool in the Prisma SD-WAN portal allows the engineer to capture live packets on the WAN interface and inspect the IP header ToS/DSCP field?
Antwort: D
Begründung:
Comprehensive and Detailed Explanation
To validate specific packet-level details like DSCP (Differentiated Services Code Point) values, header checksums, or exact payload sizes, a Packet Capture (PCAP) is required.
PCAP Tool: Prisma SD-WAN provides a built-in PCAP utility accessible directly from the portal. The engineer can select the specific Interface (e.g., Internet 1), apply a Filter (e.g., port 5060 or host 1.2.3.4), and capture the traffic.
Analysis: The resulting .pcap file can be downloaded and opened in Wireshark. This allows the engineer to definitively see if the packets leaving the ION have DSCP EF (46) and if the packets arriving (if capturing on the other side) still retain that marking, or if the ISP has bleached it to CS0 (0).
Flow Browser (A): While it shows "Application" and metrics, the Flow Browser typically displays the assigned priority class, not necessarily the raw bit-level DSCP value present in the packet header on the wire.
44. Frage
Which specialized hardware feature is available on the ION 9000 series but NOT on the ION 3000 series, making it suitable for high-throughput Data Center deployments?
Antwort: D
Begründung:
Comprehensive and Detailed Explanation
The ION 9000 is the flagship high-performance hardware model designed for large Data Centers and Campus Cores.
10GbE Connectivity (C): The defining hardware differentiator for the ION 9000 is its inclusion of multiple 10 Gigabit Ethernet (SFP+) interfaces. This allows it to interconnect with Data Center core switches at 10Gbps speeds, supporting the multi-gigabit aggregate throughput required for hub sites aggregating traffic from hundreds of branches.
ION 3000: The ION 3000 is a branch-tier device limited to 1 Gigabit Ethernet (copper/SFP) interfaces.
Bypass Pairs (B): Both models (and others like ION 2000/7000) support Bypass Pairs.
LTE/PoE (A/D): These are typically features of smaller branch/edge models (like ION 1200), not the high-end DC concentrators.
45. Frage
BGP core peers on data center IONs are learning only a default route from the core router. Which action will protect the SD-WAN network from getting isolated in the event of BGP misconfiguration on the core routers?
Antwort: D
Begründung:
In a Data Center (DC) deployment, the ION device typically peers with a core router via Border Gateway Protocol (BGP) to exchange reachability information between the SD-WAN fabric and the legacy corporate network.2 When the ION is configured to learn only a default route ($0.0.0.0/0$) from the core, the entire SD- WAN fabric relies on this single BGP-learned route to reach internal resources not directly connected to the ION.
The primary risk in this design is network isolation caused by a BGP misconfiguration or a "soft failure" on the core router. If the BGP session stays "Up" but the core router stops advertising the default route due to a configuration error, the ION device will remove the route from its routing table. Without a valid path to the core, the branch sites connected to the DC ION will lose connectivity to all data center resources.
To mitigate this, the recommended best practice is to add a static default route with a higher Administrative Distance (AD) pointing to the core peer IPs.3 This acts as a "floating static route." Under normal operations, the BGP-learned default route (typically with an AD of 20 for eBGP) remains active in the routing table. If the BGP advertisement fails, the static route with the higher AD (e.g., 250) becomes active.
This ensures that the ION device maintains a persistent gateway toward the core infrastructure, preventing total fabric isolation and providing a fail-safe mechanism while the BGP peering issue is remediated. While BFD (Option A) helps with fast peer failure detection, it does not solve the issue of a missing prefix advertisement. Static route redundancy provides the necessary architectural "safety net" for the data center's reachability.
46. Frage
When an ION device has been claimed, the cloud-based controller generates and communicates with the device by which method?
Antwort: B
Begründung:
In the Prisma SD-WAN (formerly CloudGenix) architecture, the security and authenticity of device-to- controller communication are paramount. When a new ION (Instant-On Network) device is powered on and connected to the internet, it initiates a secure "phone home" process to the Prisma SD-WAN Cloud Controller.
To ensure that the controller is communicating with a genuine Palo Alto Networks hardware or software instance, the system utilizes a Manufacturer Installed Certificate (MIC).
The MIC is a unique digital certificate burned into the hardware's Trusted Platform Module (TPM) or secure storage during the manufacturing process. This certificate acts as the device's foundational identity. When a customer "claims" a device in the Prisma SD-WAN portal using its serial number, the controller maps that serial number to the specific MIC associated with that unit.
Once the device is claimed and attempts to connect, a mutual TLS (mTLS) handshake occurs. The ION device presents its MIC to the controller to prove its identity, and the controller validates this against its records. This method eliminates the need for manual staging, pre-configuration, or the complexity of managing a Customer Installed Certificate (CIC) or a private Public Key Infrastructure (PKI) during the initial deployment phase. By leveraging the MIC, Prisma SD-WAN achieves true Zero Touch Provisioning (ZTP), ensuring that only authorized, authentic devices can join the fabric and receive configuration policies, thereby maintaining a secure and automated onboarding workflow.
