Question 141

Which configuration is used to define how an ION device connects to a WAN provider?

1. Security zone
2. Application definition
3. Circuit configuration
4. User-ID

Correct Answer: 3

Explanation

Circuit configuration defines the logical characteristics of a WAN connection used by an ION device. It provides the SD-WAN system with information about the transport and allows the circuit to participate in routing, path selection, and other network functions. A properly configured circuit must correspond to the intended physical or logical connectivity available at the site. Security zones classify traffic for security policies, application definitions identify traffic, and User-ID provides identity information. When troubleshooting a WAN path, administrators should verify that the circuit configuration accurately represents the connected transport.

Question 142

What should be checked if a configured WAN circuit remains unavailable even though the configuration appears correct?

1. Physical and upstream connectivity
2. Application title
3. User profile image
4. QoS class name

Correct Answer: 1

Explanation

If a WAN circuit remains unavailable despite apparently correct configuration, physical and upstream connectivity should be investigated. The problem may involve cabling, an upstream device, provider connectivity, interface state, or another transport-level issue. Configuration correctness alone does not guarantee that the circuit is operational. Administrators should review interface status and available circuit information before moving into higher-level policy troubleshooting. Application names, user profile details, and QoS class labels do not determine basic WAN availability. A layered troubleshooting process helps isolate whether the failure exists at the physical, interface, circuit, or policy level.

Question 143

Which SD-WAN feature allows an administrator to define different path behavior for different applications?

1. Application-aware Path Policy
2. Destination NAT
3. Route redistribution
4. Controller registration

Correct Answer: 1

Explanation

Application-aware Path Policy allows administrators to define path behavior according to application identity and other matching criteria. This capability is important because different applications can have different performance, security, and transport requirements. For example, one application may prefer a low-latency path while another may be permitted to use a broader set of available transports. Destination NAT changes addressing, route redistribution exchanges routing information, and controller registration establishes device management relationships. Application-aware path policies therefore provide a mechanism for tailoring network-path behavior to specific workloads rather than treating all traffic identically.

Question 144

A policy rule has a broad match condition and another rule has a more specific condition. What should the administrator consider when placing these rules?

1. Specific rules may need appropriate precedence
2. Both rules must always use NAT
3. The broad rule must always be first
4. Rule order has no effect

Correct Answer: 1

Explanation

When multiple policy rules can match the same traffic, the administrator must consider rule precedence and ordering. A more specific rule may need to be evaluated before a broad rule so that the intended traffic receives the specific treatment. If the broad rule is evaluated first, it can handle traffic before the specific rule is reached, depending on the policy-processing model. NAT is not automatically required for either rule. Correct ordering is therefore an important part of policy design and troubleshooting. Administrators should review both match criteria and rule sequence when policy results are unexpected.

Question 145

Which object identifies an IP network or address range used as a policy match?

1. Destination prefix
2. QoS priority
3. User-ID
4. Circuit category

Correct Answer: 1

Explanation

A destination prefix identifies an IP network or address range and can be used as a policy-matching object. Prefix-based matching allows administrators to apply different traffic behavior to specific destination networks. This is useful when certain applications or network destinations require particular path, security, or performance treatment. QoS priority describes traffic handling, User-ID provides user identity information, and circuit category classifies WAN connectivity. Accurate prefix definitions are important because an incorrect network range can cause traffic to miss the intended rule or match an unintended policy. Administrators should verify both the prefix value and its policy usage.

Question 146

Which policy type is most directly responsible for translating private source addresses for Internet-bound traffic?

1. Performance Policy
2. NAT Policy
3. Path Policy
4. QoS Policy

Correct Answer: 2

Explanation

NAT Policy controls address translation, including source NAT for traffic leaving a private network toward the Internet or another network requiring translated addressing. Source NAT replaces the original source address with a configured translated address or address pool according to the applicable rule. Performance Policy evaluates application behavior, Path Policy influences network-path selection, and QoS Policy controls traffic classification and prioritization. When Internet-bound traffic fails because the destination sees an unexpected source address or cannot return traffic, administrators should review the applicable NAT configuration along with routing and interface status.

Question 147

What is the purpose of an application definition in Prisma SD-WAN?

1. Identify traffic as a particular application
2. Assign an IP address to an interface
3. Establish a physical WAN connection
4. Replace a routing protocol

Correct Answer: 1

Explanation

An application definition identifies network traffic as belonging to a particular application or application category. Accurate application identification enables Prisma SD-WAN policies to make application-aware decisions for path selection, performance handling, security, and QoS. Without appropriate identification, traffic may not match the intended application-specific policy. Application definitions do not assign interface addresses, establish physical WAN connections, or replace routing protocols. Administrators should verify that application definitions accurately represent the traffic they intend to control, particularly when creating policies that depend on application identity and performance requirements.

Question 148

Which situation most clearly justifies using a custom application definition?

1. Existing application identification does not adequately match required traffic
2. A WAN cable needs replacement
3. An interface needs a new IP address
4. A routing neighbor must be restarted

Correct Answer: 1

Explanation

A custom application definition can be appropriate when existing application identification does not adequately represent traffic that an organization needs to control. Accurate identification is especially important when application-specific Path, Performance, QoS, or Security Policies depend on that classification. Creating a custom definition allows administrators to describe traffic according to supported matching characteristics that better represent the required application behavior. It is unrelated to replacing WAN cables, assigning interface addresses, or restarting routing neighbors. Before creating one, administrators should confirm that an existing application definition cannot already provide the required match.

Question 149

What is the primary function of an ION device’s data-plane processing?

1. Forward traffic according to routing and SD-WAN policy decisions
2. Store user documents
3. Manage employee payroll
4. Generate email accounts

Correct Answer: 1

Explanation

ION data-plane processing handles network traffic at the site and forwards packets according to routing, path-selection, security, NAT, QoS, and other applicable configuration. This local processing allows branch traffic to be handled at the edge rather than requiring every packet to pass through centralized management infrastructure. User documents, payroll, and email-account management are unrelated functions. Understanding the data plane is useful when diagnosing traffic problems because a healthy controller connection does not necessarily mean every forwarding decision is correct, and a controller issue does not automatically mean local traffic forwarding has stopped.

Question 150

What is the main purpose of centralized Prisma SD-WAN policy management?

1. Apply consistent configuration and policy across managed sites
2. Eliminate all local forwarding
3. Replace every endpoint application
4. Disable WAN path selection

Correct Answer: 1

Explanation

Centralized Prisma SD-WAN policy management allows administrators to define and maintain configuration and policy from a central management environment and apply those settings to managed sites. This approach improves consistency across branches while still allowing appropriate site-specific differences. Centralized management does not mean that local ION devices stop forwarding traffic. The devices continue performing site-level traffic processing based on their effective configuration. Centralized policy management also does not replace endpoint applications or disable path selection. Its primary value is coordinated configuration, visibility, and operational control across the SD-WAN deployment.

Question 151

A site uses broadband as its preferred transport and LTE as an alternative when broadband becomes unsuitable. Which configuration concept is relevant?

1. Backup path
2. User-ID
3. Destination prefix
4. No NAT

Correct Answer: 1

Explanation

The backup-path concept is relevant when one transport is intended to serve as an alternative to another transport. In this scenario, broadband can be treated as the preferred path while LTE provides additional connectivity when the preferred path is unavailable or no longer meets applicable requirements. SD-WAN path-selection logic can evaluate available transports according to configured policies and performance conditions. User-ID identifies users, destination prefixes identify network ranges, and No NAT controls address translation. Proper backup-path design helps maintain application connectivity while allowing organizations to use different WAN transports according to their intended roles.

Question 152

Which link-quality metric measures the percentage or proportion of packets that fail to arrive successfully?

1. Latency
2. Jitter
3. Packet loss
4. DSCP

Correct Answer: 3

Explanation

Packet loss measures the portion of transmitted packets that fail to reach the intended destination successfully. It is a key indicator of WAN quality because lost packets can cause retransmissions, degraded application performance, or interruptions in real-time traffic. Latency measures delay, jitter measures variation in packet arrival timing, and DSCP provides traffic-classification information. Prisma SD-WAN can evaluate packet loss along with other link-quality metrics when determining whether a path meets configured requirements. Administrators should monitor packet loss trends rather than relying only on whether a circuit is technically connected.

Question 153

Which action is appropriate when traffic should be allowed through a Security Policy rule?

1. Reject
2. Allow
3. Drop
4. No NAT

Correct Answer: 2

Explanation

The Allow action permits traffic that matches the applicable Security Policy rule. Security policies can evaluate multiple traffic characteristics, including source and destination zones, addresses, applications, and user identity where supported. When a rule matches and uses Allow, the traffic is permitted to proceed subject to other applicable processing and policies. Reject and Drop prevent matching traffic from continuing, while No NAT is an address-translation action rather than a security decision. Administrators should verify the rule’s match conditions and ordering when traffic that should be allowed is unexpectedly blocked.

Question 154

Which policy would an administrator inspect when an application should move to another path after its performance falls below configured requirements?

1. Performance Policy
2. NAT Policy
3. QoS Policy
4. Security Policy

Correct Answer: 1

Explanation

Performance Policy should be inspected when an application needs to respond to performance degradation according to configured requirements. Such policies can use application and network performance measurements to determine whether traffic remains on its current path or requires a corrective action such as moving flows. NAT Policy handles address translation, QoS Policy manages traffic treatment, and Security Policy controls access. When investigating unexpected path movement or a failure to move traffic, administrators should examine the relevant performance rules, application metrics, thresholds, actions, and available alternative paths.

Question 155

Why are latency, packet loss, and jitter considered important link-quality measurements?

1. They describe different aspects of network-path performance
2. They identify employee passwords
3. They create security zones
4. They replace application definitions

Correct Answer: 1

Explanation

Latency, packet loss, and jitter describe different aspects of network-path performance and together provide a broader view of transport quality. Latency represents delay, packet loss represents unsuccessful packet delivery, and jitter represents variation in packet arrival timing. An application may tolerate one condition but perform poorly when another becomes excessive. Prisma SD-WAN can use these measurements when evaluating path suitability for application traffic. They do not identify users, create security zones, or replace application definitions. Considering multiple metrics helps SD-WAN decisions reflect actual transport conditions rather than relying on a single measurement.

Question 156

Which configuration helps determine the secure logical connectivity between Prisma SD-WAN sites?

1. Prisma SD-WAN VPN overlay
2. QoS priority
3. User-ID
4. Application icon

Correct Answer: 1

Explanation

The Prisma SD-WAN VPN overlay provides secure logical connectivity between participating SD-WAN sites while using underlying WAN transports to carry the traffic. This overlay model separates logical site-to-site connectivity from the characteristics of individual physical circuits. Administrators can therefore use different available transports while maintaining the intended overlay relationship. QoS priority controls traffic treatment, User-ID provides identity information, and an application icon has no role in establishing network connectivity. When troubleshooting overlay communication, administrators should verify the participating sites, underlying circuits, interface status, and tunnel or overlay state.

Question 157

What should be verified after making a significant centralized policy change?

1. Effective configuration and behavior at the intended site
2. Employee screen resolution
3. Keyboard language
4. Desktop background

Correct Answer: 1

Explanation

After a significant centralized policy change, administrators should verify that the effective configuration reached the intended site and that actual traffic behavior reflects the change. This includes checking deployment status, policy association, rule ordering, and relevant operational information on the affected ION device. A policy can be correctly defined centrally but still produce unexpected results if it is not associated with the intended site or if another rule takes precedence. Endpoint display settings are unrelated. Post-change verification is an important operational practice because it confirms both configuration deployment and practical traffic behavior.

Question 158

A branch has a working route to a destination, but the application remains unreachable. Which additional component should be investigated?

1. Security policy processing
2. Monitor brightness
3. Desktop theme
4. Keyboard layout

Correct Answer: 1

Explanation

If routing appears correct but an application remains unreachable, security policy processing should be investigated as one possible cause. A valid route only establishes that the device has a forwarding entry; it does not guarantee that the traffic is permitted through every subsequent policy stage. Security rules may block traffic based on zones, applications, users, addresses, or other matching criteria. Administrators should also consider NAT, interface status, path selection, and return-path behavior. Reviewing security-policy matches and actions can help determine whether access control, rather than routing, is preventing successful application connectivity.

Question 159

What does the Direct overlay option generally represent in Prisma SD-WAN path configuration?

1. Traffic using the available transport without the Prisma SD-WAN VPN overlay
2. Traffic that must always use LTE
3. Traffic that bypasses every security policy
4. Traffic that disables routing

Correct Answer: 1

Explanation

The Direct overlay option generally represents traffic that can use the available transport without establishing the Prisma SD-WAN VPN overlay for that path. This differs from a Prisma SD-WAN VPN path, where logical secure overlay connectivity is used between participating sites. Direct does not mean that traffic automatically bypasses security policies or routing. The actual behavior remains subject to the configured network and security architecture. Administrators should select the appropriate overlay type based on the desired topology, security requirements, and traffic-flow design for the specific application or site connection.

Question 160

Which troubleshooting sequence is most logical when an application cannot communicate across an SD-WAN site?

1. Check connectivity, routing, policy matching, and path conditions
2. Change the user’s desktop theme
3. Delete all application definitions
4. Disable every WAN circuit

Correct Answer: 1

Explanation

A logical troubleshooting sequence starts with basic connectivity and then moves through routing, policy matching, and path conditions. Administrators should first confirm that the relevant interfaces and circuits are operational, then verify route availability and overlay connectivity where applicable. Next, they should inspect Security, Path, NAT, QoS, or Performance Policy behavior according to the symptoms. Finally, link-quality and application-performance conditions should be considered if path selection is involved. This layered method reduces unnecessary configuration changes and helps isolate whether the problem originates in connectivity, routing, policy processing, or application-aware SD-WAN behavior.
