Question 61.

An administrator wants to allow a business application while applying intrusion inspection and file analysis. Which access control action is most appropriate?

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

Correct Answer: 1

Explanation:

The Allow action permits matching traffic and can still apply additional security inspection such as intrusion prevention and file policies. Trust bypasses deeper inspection and is therefore not appropriate when the administrator wants to analyze the permitted session. Block denies the connection, while Interactive Block is intended for user-facing warning scenarios. An Allow rule with the required inspection policies attached provides both access and security visibility.

Question 62.

Which feature can block connections to known malicious domains or IP addresses before they reach deeper inspection stages?

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

Correct Answer: 4

Explanation:

Security Intelligence provides early filtering based on known malicious or trusted indicators such as IP addresses, networks, domains, and URLs. This allows the firewall to stop clearly unwanted traffic before performing more resource-intensive access control or intrusion inspection. Health monitoring tracks device status, file policies inspect transferred files, and routing determines forwarding paths. Security Intelligence is therefore the appropriate mechanism for early reputation-based traffic enforcement.

Question 63.

Which policy type controls the Snort rules used to detect and prevent exploit traffic?

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

Correct Answer: 3

Explanation:

An intrusion policy controls which Snort rules are enabled and how suspicious or malicious traffic is handled. It can be associated with access control rules so that matching traffic is inspected for exploits, protocol violations, and other attack patterns. 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 64.

An internal server must use a fixed public address so external users can reliably reach it. Which NAT configuration is most appropriate?

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

Correct Answer: 2

Explanation:

Static NAT creates a consistent mapping between the internal server address and a public translated address. This is well suited for externally reachable services because clients can always use the same public IP address. Dynamic PAT is typically used for many internal clients sharing one public address for outbound access. Identity NAT keeps the original address unchanged. A stable published server therefore generally requires static translation.

Question 65.

A broad access control Allow rule is positioned above a specific deny rule, and traffic that should be blocked is being permitted. What should the administrator do?

1. Reorder the rules so the specific deny rule is evaluated before the broad Allow rule
   2. Disable NAT
   3. Restart the Management Center
   4. Replace the Threat Defense device

Correct Answer: 1

Explanation:

Access control policy rules are order-sensitive. If a broad Allow rule matches traffic before a more specific deny rule, the later rule may never evaluate the connection. The administrator should review rule conditions and move the more specific rule to the appropriate position. Restarting Management Center or changing unrelated NAT configuration will not fix a rule-precedence problem.

Question 66.

Which behavior is associated with the Trust action in an access control policy?

1. Traffic is always blocked
   2. Traffic is redirected through a captive portal
   3. Traffic receives maximum intrusion inspection
   4. Matching traffic is allowed while bypassing additional inspection

Correct Answer: 4

Explanation:

The Trust action allows matching traffic and bypasses further deep inspection. This can improve performance for explicitly trusted traffic, but it also reduces visibility and security analysis. Trust should therefore be used carefully and only where the risk is understood. An Allow action is more appropriate when traffic must be permitted while still receiving intrusion, file, or malware inspection.

Question 67.

Which event source is most useful for determining whether a file was identified as malicious during transfer?

1. Routing events
   2. Health events
   3. File and malware events
   4. Deployment events

Correct Answer: 3

Explanation:

File and malware events provide visibility into files observed and analyzed by Secure Firewall security controls. They can contain information such as file type, hash, transfer context, disposition, and malware verdict where supported. This makes them the appropriate source when determining whether a transferred file was classified as malicious. Routing, health, and deployment events do not provide equivalent file-analysis information.

Question 68.

An organization wants to create an access rule that applies only to members of a specific directory group. Which capability is required?

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

Correct Answer: 2

Explanation:

Identity-based access control allows firewall policies to reference users and groups instead of relying only on IP addresses. The firewall can use supported identity sources to associate network sessions with users, enabling policies such as permitting a business application only for a specific directory group. NAT, dynamic routing, and high availability do not provide user-aware policy enforcement.

Question 69.

A user is unexpectedly blocked from a web category that should be permitted. What should the administrator review first?

1. The URL filtering conditions and the access control rule that matched the request
   2. Only the interface counters
   3. Only the routing table
   4. The firewall serial number

Correct Answer: 1

Explanation:

If web traffic is blocked based on category, the administrator should first review the relevant access control rule and its URL filtering conditions. The website may have been categorized differently than expected, or the session may have matched another rule. Connection and URL-related event information can help identify the policy decision. Interface and routing information do not directly explain category-based policy enforcement.

Question 70.

Which feature is required if a Secure Firewall must inspect the payload of outbound HTTPS sessions for malware?

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

Correct Answer: 4

Explanation:

HTTPS encrypts application content, limiting visibility into the payload. TLS/SSL decryption allows the firewall to decrypt eligible sessions, apply security inspection, and then process the traffic according to policy. This enables malware, file, application, and intrusion analysis of content that would otherwise remain encrypted. Routing, PAT, and high availability do not expose encrypted application payloads.

Question 71.

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

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

Correct Answer: 3

Explanation:

Application identification examines traffic characteristics beyond simple port numbers. This allows Secure Firewall to recognize applications that use dynamic ports, tunnel over common ports, or otherwise avoid fixed port assignments. Administrators can then create access control rules based on applications or application categories. NAT and high availability serve different functions, while health monitoring focuses on operational status.

Question 72.

An administrator has changed several access control rules in Management Center, but the firewall behavior has not changed. What should be checked first?

1. Whether every endpoint has been rebooted
   2. Whether the updated policy has been deployed successfully
   3. Whether OSPF was disabled
   4. Whether all NAT rules were deleted

Correct Answer: 2

Explanation:

Changes made in Secure Firewall Management Center do not become active on managed Threat Defense devices until they are deployed. The administrator should check whether there are pending changes and verify that deployment completed successfully. If deployment failed, the task information may identify the issue. Rebooting endpoints or changing unrelated routing and NAT settings would not address a normal undeployed-policy situation.

Question 73.

Which capability should an administrator use to determine whether a managed Threat Defense device has high CPU or memory utilization?

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

Correct Answer: 1

Explanation:

Health monitoring provides operational information about managed devices, including resource usage, connectivity status, interfaces, and other health conditions. It is the appropriate feature for identifying CPU, memory, or similar operational issues. File inspection, URL filtering, and Security Intelligence process or classify traffic but do not provide the same device-health visibility.

Question 74.

Which design provides firewall redundancy so that a peer can continue forwarding traffic if the active appliance fails?

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

Correct Answer: 4

Explanation:

High availability pairs compatible firewall devices to reduce service disruption when one appliance fails. The standby peer can assume the forwarding role according to the supported HA design, while configuration and relevant state information are synchronized. Dynamic PAT, URL filtering, and file policies provide networking or security functions but do not provide device-level failover.

Question 75.

Which troubleshooting source should be reviewed first when an administrator wants to know which rule blocked a particular connection?

1. Only NAT configuration
   2. Only interface statistics
   3. Connection event details and the associated rule match
   4. Only routing neighbor information

Correct Answer: 3

Explanation:

Connection events are the best initial source for understanding how a specific session was handled. When logging is configured, they can provide the source, destination, application, action, user, zones, and matched access control rule. This allows the administrator to identify the rule responsible for the block before investigating additional components such as NAT, decryption, or intrusion policy.

Question 76.

A browser begins showing certificate warnings immediately after TLS decryption is enabled. What should the administrator verify first?

1. Static route metrics
   2. That the endpoint trusts the certificate authority used by the firewall for decryption
   3. Dynamic PAT port usage
   4. High-availability failover status

Correct Answer: 2

Explanation:

During outbound TLS decryption, the firewall can generate certificates for destination sites and sign them using a configured CA. Client devices must trust this CA. If they do not, browsers and applications may display certificate warnings. Therefore, the endpoint trust store and the configured decryption CA should be checked first. Routing and PAT do not normally cause certificate trust errors introduced by decryption.

Question 77.

A user connects to a prohibited website category, and the organization wants to display a warning page that lets the user continue when policy permits. Which action should be configured?

1. Interactive Block
   2. Trust
   3. Static NAT
   4. Security Intelligence Block

Correct Answer: 1

Explanation:

Interactive Block is designed to provide a browser-based warning page for matching web traffic and can allow the user to continue when the policy permits that behavior. It is useful when an organization wants to discourage rather than absolutely deny access. Trust simply allows traffic while bypassing inspection, while Security Intelligence blocking is intended to deny traffic to specified indicators rather than provide a user warning page.

Question 78.

Which NAT method is most appropriate when hundreds of internal hosts must share one public IPv4 address for outbound access?

1. Identity NAT
   2. Static one-to-one NAT
   3. No NAT
   4. Dynamic PAT

Correct Answer: 4

Explanation:

Dynamic PAT allows many internal hosts to share one translated public IP address by using unique source port mappings. This is widely used for outbound Internet access when public IPv4 addresses are limited. Static NAT would require separate mappings, while identity NAT does not translate the original address. Dynamic PAT therefore provides the required many-to-one translation efficiently.

Question 79.

Which policy should be used when an administrator needs to control whether executable files are detected, logged, or blocked during transfer?

1. Health policy
   2. NAT policy
   3. File policy
   4. Routing policy

Correct Answer: 3

Explanation:

A file policy defines how supported file types are handled when they traverse inspected traffic. Administrators can configure file detection, logging, blocking, and malware-related analysis depending on the security requirements and available capabilities. The file policy is typically associated with relevant access control rules. NAT and routing policies do not inspect transferred files, while health policies monitor device condition.

Question 80.

An administrator is troubleshooting traffic that should be permitted but is being denied. What is the best first step?

1. Reboot the firewall immediately
   2. Review the connection events, matched policy rule, and relevant policy stages before making changes
   3. Delete the access control policy
   4. Disable all inspection globally

Correct Answer: 2

Explanation:

Effective troubleshooting begins by gathering evidence. Connection events can show how the session was classified and which access control rule acted on it. From there, the administrator can evaluate Security Intelligence, URL filtering, NAT, TLS decryption, intrusion processing, routing, and other relevant stages. Making broad changes or rebooting the device before identifying the cause can introduce unnecessary disruption and may obscure the original problem.
