Question 101.

An administrator wants traffic to a trusted internal application to be permitted but still inspected by an intrusion policy. Which access control action should be used?

1. Allow
   2. Trust
   3. Block
   4. Interactive Block

Correct Answer: 1

Explanation:

The Allow action permits the matching traffic while still allowing additional inspection, including intrusion prevention and file inspection, when configured. Trust allows the traffic but bypasses deeper inspection, so it would not satisfy the requirement. Block denies the session entirely, while Interactive Block is designed for user-warning workflows. Therefore, Allow is the correct choice when traffic must be permitted and still receive security inspection.

Question 102.

Which feature is best suited for blocking known malicious IP addresses before traffic reaches deeper inspection engines?

1. Health monitoring
   2. Dynamic routing
   3. File policy
   4. Security Intelligence

Correct Answer: 4

Explanation:

Security Intelligence can block or allow traffic based on known IP addresses, networks, domains, and URLs before more resource-intensive inspection occurs. This makes it useful for quickly rejecting traffic associated with known malicious infrastructure. Health monitoring tracks device condition, routing determines packet forwarding, and file policies inspect transferred content. Security Intelligence is therefore the best choice for early reputation-based filtering.

Question 103.

Which policy is used to determine which Snort rules are active and how matching attack traffic is handled?

1. NAT policy
   2. Platform settings policy
   3. Intrusion policy
   4. Health policy

Correct Answer: 3

Explanation:

An intrusion policy controls the Snort rules used to detect and prevent malicious traffic. It determines which rules are enabled and how they respond to matching events. The intrusion policy can be associated with relevant access control rules. NAT policies handle address translation, platform settings configure device-level behavior, and health policies monitor operational status. Snort rule behavior is therefore managed through the intrusion policy.

Question 104.

An internal application server must always appear on the Internet using the same public IPv4 address. Which NAT method is most appropriate?

1. Dynamic PAT
   2. Static NAT
   3. Identity NAT
   4. No NAT

Correct Answer: 2

Explanation:

Static NAT provides a fixed one-to-one mapping between the internal server address and a public translated address. This is ideal for servers that external clients must reach consistently. Dynamic PAT is typically used when many internal clients share one public address for outbound access. Identity NAT preserves the original address. A stable externally reachable server therefore generally requires static NAT.

Question 105.

A specific Block rule is not taking effect because traffic is matching a broader Allow rule earlier in the policy. What should the administrator do?

1. Reorder the access control rules so the more specific rule is evaluated first
   2. Disable all NAT
   3. Restart Secure Firewall Management Center
   4. Reboot every endpoint

Correct Answer: 1

Explanation:

Access control rules are processed in sequence, so rule order is critical. A broad Allow rule can match traffic before a more specific Block rule is reached. The administrator should adjust the rule order so the more specific policy intent is evaluated first. Restarting Management Center or changing unrelated NAT configuration will not resolve a rule-precedence issue.

Question 106.

What is the primary effect of the Trust action in an access control policy?

1. It always blocks matching traffic
   2. It redirects users to an authentication portal
   3. It applies the most aggressive intrusion inspection
   4. It allows matching traffic while bypassing further inspection

Correct Answer: 4

Explanation:

The Trust action allows matching traffic and bypasses additional deep inspection. This can reduce processing overhead for traffic that has already been explicitly deemed safe. However, because it reduces security visibility, it should be used carefully. If traffic must be allowed while still receiving intrusion or file inspection, the Allow action is more appropriate.

Question 107.

Which event type should an administrator review to determine whether a transferred file was classified as malware?

1. Routing events
   2. Deployment events
   3. File and malware events
   4. Device inventory events

Correct Answer: 3

Explanation:

File and malware events provide details about files observed and analyzed by Secure Firewall security features. Depending on policy and licensing, these events can include file type, hash, transfer context, disposition, and malware verdict information. Routing, deployment, and inventory events do not provide equivalent file-level threat information. File and malware events are therefore the correct source.

Question 108.

Which capability allows access control rules to reference corporate users and directory groups?

1. Static NAT
   2. Identity-based access control
   3. High availability
   4. Dynamic routing

Correct Answer: 2

Explanation:

Identity-based access control allows Secure Firewall policies to use usernames and group membership as rule conditions. This enables the organization to permit or deny applications based on user identity rather than relying only on IP addresses. Supported identity integrations provide the context required for these policy decisions. NAT, HA, and routing do not independently provide user-aware access control.

Question 109.

A website that should be allowed is being denied because it is placed in a blocked URL category. What should the administrator review first?

1. URL classification, connection event details, and the rule that matched
   2. Only interface statistics
   3. Only the routing table
   4. The device serial number

Correct Answer: 1

Explanation:

The administrator should first determine how the website was categorized and which access control rule processed the request. The site may have been recategorized, or the connection may have matched a different rule than expected. Connection and URL-related event details provide the most useful policy context. Interface and routing information do not directly explain category-based filtering decisions.

Question 110.

Which feature must be enabled if the firewall needs to inspect encrypted HTTPS payloads for threats?

1. Dynamic routing
   2. Static NAT
   3. High availability
   4. TLS/SSL decryption

Correct Answer: 4

Explanation:

HTTPS encrypts application data, preventing full payload inspection unless the traffic is decrypted. TLS/SSL decryption allows the firewall to inspect eligible encrypted sessions for malware, intrusion attempts, application behavior, and other policy violations. Routing, NAT, and high availability do not provide visibility into encrypted application payloads.

Question 111.

Which Secure Firewall capability can identify applications even when they use shared or nonstandard ports?

1. Health monitoring
   2. High availability
   3. Application identification and control
   4. Static routing

Correct Answer: 3

Explanation:

Application identification recognizes traffic using characteristics beyond simple port numbers. This is useful because many applications use dynamic ports or common ports such as TCP 443. Application-aware policy enables administrators to control traffic more precisely based on the actual application rather than only transport-layer information. Health monitoring, HA, and routing serve different purposes.

Question 112.

An administrator modifies policy objects in Secure Firewall Management Center, but the managed device still uses the previous values. What should be verified first?

1. Whether all endpoints were restarted
   2. Whether the pending changes were deployed successfully
   3. Whether the routing table was cleared
   4. Whether all NAT rules were removed

Correct Answer: 2

Explanation:

Changes made in Secure Firewall Management Center remain pending until they are deployed to the managed Threat Defense device. The administrator should verify that deployment was initiated and completed successfully. If deployment failed, the task details can help identify the issue. Restarting endpoints or modifying unrelated routing or NAT configuration is not required for normal policy updates.

Question 113.

Which feature should an administrator use to monitor CPU utilization, memory usage, and interface condition on managed Threat Defense devices?

1. Health monitoring
   2. File inspection
   3. Security Intelligence
   4. URL filtering

Correct Answer: 1

Explanation:

Health monitoring provides operational visibility into managed Secure Firewall devices. It can report CPU, memory, interface state, process condition, communication status, and other health metrics. This helps administrators identify performance or availability issues. File inspection, Security Intelligence, and URL filtering are security-policy functions and do not provide the same operational monitoring capability.

Question 114.

Which configuration allows a second firewall appliance to assume forwarding duties if the active unit fails?

1. Dynamic PAT
   2. URL filtering
   3. Intrusion policy
   4. High availability

Correct Answer: 4

Explanation:

High availability provides redundancy by pairing compatible firewall appliances so service can continue if one device fails. Depending on the supported platform and deployment, configuration and connection state may be synchronized between peers. PAT, URL filtering, and intrusion policy are useful security or networking features, but they do not provide device-level failover.

Question 115.

Which source should be reviewed first when an administrator needs to determine which rule denied a specific network session?

1. Routing table only
   2. Interface counters only
   3. Connection event details
   4. Health alerts only

Correct Answer: 3

Explanation:

Connection events can show the source, destination, application, user, zones, action, and the access control rule associated with a session when logging is enabled. This makes them the best starting point for determining why a connection was blocked. Routing and interface data may be useful later, but they do not directly identify the policy decision.

Question 116.

Users begin receiving browser certificate warnings after outbound TLS decryption is enabled. What should the administrator verify first?

1. OSPF cost
   2. Whether endpoint devices trust the certificate authority used by the firewall
   3. Dynamic PAT port usage
   4. Interface duplex settings

Correct Answer: 2

Explanation:

Outbound TLS decryption typically requires the firewall to generate substitute certificates and sign them with a configured CA. Client devices must trust that CA. If the CA is not trusted, browsers and applications can display certificate warnings. Routing metrics, PAT usage, and duplex settings would not normally cause this symptom. Endpoint trust of the decryption CA is therefore the first item to verify.

Question 117.

Which access control action can display a warning page to a web user and permit continuation when policy allows it?

1. Interactive Block
   2. Trust
   3. Allow
   4. Security Intelligence Block

Correct Answer: 1

Explanation:

Interactive Block is designed for supported web traffic where the organization wants to warn users but still allow them to continue under defined conditions. It provides an intermediate option between unrestricted access and a hard block. Trust simply allows traffic while bypassing additional inspection, while Security Intelligence blocking denies traffic based on reputation or configured indicators.

Question 118.

Which NAT method is best when hundreds of private hosts need outbound Internet access through one public IPv4 address?

1. Static NAT
   2. Identity NAT
   3. No NAT
   4. Dynamic PAT

Correct Answer: 4

Explanation:

Dynamic PAT allows many internal hosts to share a single public IPv4 address by using different translated source ports. This makes it highly efficient for outbound Internet connectivity where public IPv4 addresses are limited. Static NAT normally provides fixed mappings, while identity NAT does not translate the source address. Dynamic PAT is therefore the appropriate solution for many-to-one translation.

Question 119.

Which policy should be used to control whether specific file types are detected, logged, or blocked during network transfer?

1. Health policy
   2. Routing policy
   3. File policy
   4. Platform settings policy

Correct Answer: 3

Explanation:

A file policy defines how supported files are handled as they traverse inspected traffic. Administrators can configure detection, logging, blocking, and malware-related analysis for selected file types. The file policy is associated with suitable access control rules. Health, routing, and platform settings policies do not provide file-type-specific content control.

Question 120.

A connection that should be allowed is unexpectedly denied. What is the best initial troubleshooting approach?

1. Reboot the firewall immediately
   2. Review the connection event, matched rule, and relevant policy stages before changing configuration
   3. Disable intrusion prevention globally
   4. Delete the access control policy

Correct Answer: 2

Explanation:

Troubleshooting should begin by gathering evidence about how the session was processed. Connection events can identify the action and matched rule, while additional review can determine whether Security Intelligence, URL filtering, NAT, decryption, intrusion inspection, or routing contributed to the result. Making broad changes or rebooting before understanding the cause can introduce unnecessary disruption and obscure the original issue.
