Question 101

What is the primary role of an ION device at a Prisma SD-WAN branch?

1. Store application backups
2. Provide endpoint antivirus protection
3. Process and forward network traffic
4. Manage user passwords

Correct Answer: 3

Explanation

An ION device performs important data-plane functions at a Prisma SD-WAN branch. It processes traffic entering and leaving the site, applies configured policies, evaluates available paths, and forwards packets according to routing and SD-WAN decisions. Although centralized controllers provide management and control functions, traffic does not need to pass through the controller for ordinary branch forwarding. The ION therefore serves as the local networking component that implements the centralized configuration at the site. Understanding this distinction is important when troubleshooting whether a problem involves centralized management or actual branch traffic forwarding.

Question 102

Which configuration helps determine how traffic should be classified according to the WAN connection it uses?

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

Correct Answer: 1

Explanation

Circuit configuration provides the logical definition of a WAN connection and helps Prisma SD-WAN understand the characteristics and role of that transport. Circuits can represent different types of connectivity and can participate in path-selection decisions. Proper circuit configuration is therefore important when administrators want the system to distinguish between available WAN transports. User identity, security-zone descriptions, and application interface elements serve different purposes. If a circuit is incorrectly configured, the ION device may not treat the WAN connection as intended, potentially affecting path availability, policy matching, and application traffic behavior.

Question 103

Why are WAN circuit categories useful in Prisma SD-WAN?

1. They identify the physical rack location
2. They classify different types of WAN connectivity
3. They create application usernames
4. They replace routing protocols

Correct Answer: 2

Explanation

WAN circuit categories help classify different types of connectivity available to a Prisma SD-WAN site. This classification can provide useful information for policy and path-selection decisions because different transports may have different characteristics, costs, reliability, or intended uses. For example, an organization may treat broadband, private connectivity, and cellular access differently when defining traffic behavior. Circuit categories do not identify users or replace routing protocols. Their purpose is to provide a logical classification of WAN transport so that SD-WAN policies can make more informed decisions about how available connections should be used.

Question 104

An administrator wants to verify whether an ION device is successfully participating in centralized management. Which status should be reviewed?

1. Controller connectivity status
2. Monitor brightness
3. Application window size
4. User desktop theme

Correct Answer: 1

Explanation

Controller connectivity status is an important indicator of whether an ION device can communicate with the centralized Prisma SD-WAN management infrastructure. If the controller connection is unavailable, configuration synchronization, management operations, and centralized visibility may be affected. Administrators should examine the controller connection state along with relevant network reachability and device status when troubleshooting management problems. Local forwarding may continue under some circumstances, so controller status should not automatically be interpreted as proof that all data-plane traffic has stopped. Separating controller connectivity from traffic forwarding is important for accurate troubleshooting.

Question 105

What is the purpose of a security zone in a Prisma SD-WAN security policy?

1. To identify a logical security boundary for traffic
2. To measure packet jitter
3. To assign WAN bandwidth
4. To translate IP addresses

Correct Answer: 1

Explanation

A security zone represents a logical security boundary that can be used to classify traffic for security policy evaluation. By associating interfaces or traffic sources with appropriate zones, administrators can create rules describing which traffic is permitted between different network areas. Zones provide a logical structure for policy enforcement and can help separate trusted, untrusted, internal, external, or other traffic domains. They do not measure network performance, assign bandwidth, or perform address translation. Those functions belong to different parts of the SD-WAN configuration. Proper zone design supports predictable and manageable security-policy behavior.

Question 106

Which policy is specifically concerned with determining whether network traffic should be permitted or blocked?

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

Correct Answer: 2

Explanation

Security Policy determines whether traffic matching defined criteria should be permitted or blocked. Rules can evaluate attributes such as source and destination zones, prefixes, applications, users, and other supported characteristics. The resulting action controls whether the matching traffic is allowed to continue or is prevented from proceeding. Path Policy focuses on path selection, QoS Policy manages traffic treatment and prioritization, and Performance Policy addresses application performance conditions and related actions. Keeping these functions separate helps administrators troubleshoot policy behavior more effectively and ensures that each policy type is used for its intended purpose.

Question 107

A company needs to prioritize voice traffic during periods of congestion. Which QoS capability is most relevant?

1. Priority-based traffic classification
2. Destination translation
3. Controller registration
4. Route redistribution

Correct Answer: 1

Explanation

Priority-based traffic classification allows important traffic such as voice to receive preferential treatment when network resources become constrained. QoS policies can classify traffic and associate it with an appropriate priority or service level so that critical applications receive suitable network resources. This does not change the destination address, establish controller registration, or redistribute routes. Proper classification is particularly important for delay-sensitive applications because congestion can cause quality degradation even when the underlying WAN circuit remains operational. Administrators should combine traffic classification with suitable bandwidth and QoS policy settings to achieve predictable behavior.

Question 108

Which metric represents the variation in packet delivery timing across a network path?

1. Packet loss
2. Bandwidth
3. Jitter
4. Prefix length

Correct Answer: 3

Explanation

Jitter represents variation in packet arrival timing across a network path. It is particularly significant for applications that depend on consistent packet delivery, including voice, video conferencing, and other real-time communications. A path can have acceptable average latency while still experiencing high jitter, which can negatively affect application quality. Packet loss measures packets that fail to reach their destination, while bandwidth represents available transmission capacity. Prefix length describes an IP network’s addressing range. Prisma SD-WAN can consider jitter along with other link-quality measurements when determining whether a path meets configured application requirements.

Question 109

What is the primary benefit of application-aware path selection?

1. It allows traffic decisions to account for application requirements
2. It removes the need for IP addresses
3. It converts every WAN circuit into a LAN
4. It disables security processing

Correct Answer: 1

Explanation

Application-aware path selection allows Prisma SD-WAN to make forwarding decisions based on the requirements and behavior of specific applications. Instead of treating all traffic identically, administrators can define policies that influence which paths are appropriate for different application categories. This is useful because applications can have different sensitivity to latency, loss, jitter, availability, or bandwidth. Application-aware decisions do not eliminate IP addressing or security processing. They complement routing and security functions by adding application context to path selection. This approach helps organizations use multiple WAN transports more effectively while maintaining application-specific requirements.

Question 110

Which path-selection metric directly measures the time required for packets to travel across a network path?

1. DSCP
2. Latency
3. Prefix
4. NAT

Correct Answer: 2

Explanation

Latency measures the time associated with packet transmission across a network path. It is an important link-quality metric because applications such as voice, interactive services, and transaction systems can become less responsive when network delay increases. Prisma SD-WAN can use latency together with other measurements such as loss and jitter when evaluating path suitability. DSCP is used for traffic classification, prefixes identify address ranges, and NAT changes packet addressing. Understanding latency as a measurable path characteristic helps administrators interpret application performance problems and determine whether an available WAN circuit continues to satisfy configured requirements.

Question 111

What does a “No NAT” rule accomplish for matching traffic?

1. It prevents address translation for that traffic
2. It forces destination translation
3. It changes the DSCP value
4. It selects the lowest-latency path

Correct Answer: 1

Explanation

A No NAT rule specifies that matching traffic should not undergo network address translation. This is useful when the original source and destination addresses must remain unchanged as traffic crosses the relevant network boundary. Applying translation when it is unnecessary can cause routing, return-path, or application problems, particularly in internal network communication. Destination translation and source translation are separate NAT functions, while DSCP modification and path selection belong to other policy areas. Administrators should therefore use No NAT when the addressing information in the original packet needs to be preserved through the configured traffic-processing path.

Question 112

Which policy action is designed to move an application flow from its current path to another available path when conditions require it?

1. Mark
2. Reject
3. Move Flows
4. No NAT

Correct Answer: 3

Explanation

Move Flows is a Performance Policy action used when application performance conditions indicate that traffic should be moved from its current path. When configured requirements are no longer satisfied and a suitable alternative exists, this action can help maintain application performance by directing the flow toward another path. Mark is associated with traffic classification or marking behavior, Reject controls security treatment, and No NAT controls address translation. Move Flows is therefore specifically relevant when the administrator wants application traffic to respond dynamically to changing network conditions rather than remaining permanently tied to one transport.

Question 113

Why might an administrator configure a custom application definition?

1. To identify application traffic that is not adequately represented by existing definitions
2. To replace the ION operating system
3. To disable WAN circuits
4. To remove routing information

Correct Answer: 1

Explanation

A custom application definition can be useful when an organization’s traffic needs to be identified in a way that existing application definitions do not adequately provide. Accurate application identification is important because Prisma SD-WAN policies can use application identity when making path, performance, QoS, or security decisions. A custom definition can therefore provide more precise policy matching for specialized or organization-specific traffic patterns. It does not replace the ION operating system, disable WAN connectivity, or remove routing information. Administrators should ensure that custom application criteria accurately identify the intended traffic without unintentionally matching unrelated flows.

Question 114

What is the purpose of a Network Context in Prisma SD-WAN policy configuration?

1. To provide logical network information that can be referenced by policies
2. To store endpoint passwords
3. To replace all security zones
4. To measure WAN jitter

Correct Answer: 1

Explanation

A Network Context provides logical network information that can be referenced when defining and applying Prisma SD-WAN policies. It helps administrators organize network-related information and create policy behavior based on the relevant logical context. Network contexts are not intended to function as password stores, security-zone replacements, or performance-measurement mechanisms. Keeping logical network information organized can make policy configuration easier to manage, particularly in environments with multiple sites, network segments, and traffic requirements. Administrators should understand how network contexts relate to other policy objects so that rules match the intended traffic and destinations.

Question 115

Which statement best describes a Prisma SD-WAN overlay?

1. A logical connectivity layer built across underlying WAN transports
2. A replacement for every physical interface
3. A user authentication database
4. A local application cache

Correct Answer: 1

Explanation

A Prisma SD-WAN overlay is a logical connectivity layer that operates across underlying WAN transports. The overlay allows SD-WAN sites to establish logical communication while abstracting some of the differences between the physical circuits carrying the traffic. This architecture can support secure site connectivity and application-aware path selection across multiple transports. An overlay does not replace physical interfaces because those interfaces still provide the actual network connectivity. It is also unrelated to user authentication databases or application caches. Understanding the distinction between underlay transports and overlay connectivity is fundamental to SD-WAN design and troubleshooting.

Question 116

An administrator sees that a tunnel is configured but its status is not operational. What should be checked before changing application policies?

1. Underlay reachability and participating interface status
2. User profile photographs
3. Application font settings
4. Keyboard language

Correct Answer: 1

Explanation

Before changing application policies, the administrator should verify the underlay reachability and the status of the interfaces participating in the tunnel. An overlay tunnel depends on functioning underlying connectivity, so a physical or logical WAN problem can prevent the tunnel from becoming operational regardless of application policy settings. Interface state, addressing, routing, and relevant connectivity should therefore be reviewed first. If the underlay is healthy, troubleshooting can proceed toward overlay configuration and tunnel-specific conditions. This layered approach avoids changing unrelated application policies when the underlying connectivity itself is responsible for the tunnel failure.

Question 117

Which routing protocol is commonly used when an enterprise needs dynamic internal route exchange based on link-state information?

1. OSPF
2. FTP
3. SMTP
4. DNS

Correct Answer: 1

Explanation

OSPF, or Open Shortest Path First, is a dynamic routing protocol that uses link-state information to calculate routes within an autonomous system. In supported enterprise network designs, OSPF can provide dynamic route exchange between network devices and reduce dependence on manually configured static routes. FTP is a file-transfer protocol, SMTP is associated with email delivery, and DNS resolves names to network information. When OSPF is integrated with an SD-WAN environment, administrators should consider how learned routes interact with existing routing, forwarding, path selection, and policy behavior to maintain predictable connectivity.

Question 118

What is the main purpose of route filtering when exchanging routes between network domains?

1. To control which routes are accepted or advertised
2. To increase packet encryption automatically
3. To change application identities
4. To assign QoS priority to every packet

Correct Answer: 1

Explanation

Route filtering controls which routes are accepted, advertised, or redistributed between routing domains. This allows administrators to prevent unnecessary or inappropriate prefixes from entering a routing table or being propagated to other network segments. Filtering can improve routing control and reduce the risk of accidental route propagation or undesirable forwarding paths. It does not automatically encrypt packets, identify applications, or assign QoS priority. In an SD-WAN deployment, carefully designed route filtering can help maintain predictable routing behavior when dynamic routing protocols interact with branch, data-center, cloud, or other network environments.

Question 119

Why is route-policy design important when integrating dynamic routing with SD-WAN?

1. It helps control route selection and propagation
2. It eliminates all WAN circuits
3. It disables application recognition
4. It converts security policies into QoS rules

Correct Answer: 1

Explanation

Route-policy design helps administrators control how routes are selected, accepted, modified, or propagated within an integrated SD-WAN routing environment. Without appropriate control, dynamic routing can introduce prefixes that are unnecessary or undesirable for a particular site. Route policies can help maintain predictable routing behavior and prevent unintended route propagation between network domains. They do not eliminate WAN circuits or change the fundamental purpose of application recognition and security policies. Careful route-policy planning is especially important in larger environments where multiple routing sources, sites, and connectivity domains interact with Prisma SD-WAN forwarding decisions.

Question 120

A branch has multiple available WAN paths, but one path is intended to be used only when preferred paths fail to meet requirements. Which configuration concept supports this design?

1. Backup path
2. User-ID
3. No NAT
4. DSCP No Action

Correct Answer: 1

Explanation

A backup path is designed to provide an alternative when preferred paths are unavailable or no longer meet the applicable requirements. This allows an administrator to define a hierarchy of usable connectivity rather than treating every circuit as equally preferred for all traffic. When conditions on the preferred path deteriorate, the SD-WAN system can use the configured backup option when policy and path conditions permit. User-ID provides identity information, No NAT controls address translation, and DSCP No Action preserves existing packet markings. Backup-path configuration therefore contributes directly to resilient application connectivity across multiple WAN transports.
