FCP_FAZ_AN-7.4 Dumps with Practice Exam Questions Answers

When a generated report does not contain the expected information even though the logs are confirmed to be present, it typically indicates an issue with the report's configuration. There are a few common reasons this might happen:

Option A - Check the Time Frame Covered by the Report:

Reports are generated based on a specific time frame. If the report’s time frame does not cover the period when the relevant logs were collected, those logs won’t appear in the report output. Verifying and adjusting the time frame is essential to ensure the report includes all relevant data.

Conclusion:Correct.

Option B - Disable Auto-Cache:

Auto-cache is designed to improve report generation speed by using cached data. Disabling auto-cache would typically only be relevant if the report is pulling outdated data from cache, but it doesn’t directly affect whether specific logs are included in a report.

Conclusion:Incorrect.

Option C - Increase the Report Utilization Quota:

The report utilization quota is related to the resource limits for generating reports. It does not directly influence whether certain data appears in a report. Increasing this quota would help only if there are resource issues preventing the report from completing, not if specific logs are missing from the report.

Conclusion:Incorrect.

Option D - Test the Dataset:

Datasets determine which logs and data fields are pulled into the report. If a dataset is configured incorrectly or does not include the required log fields, it could lead to missing information. Testing the dataset allows you to verify that it’s correctly configured and pulling the expected data.

Conclusion:Correct.

Conclusion:

Correct Answer:A. Check the time frame covered by the reportandD. Test the dataset.

These steps directly address the issues that could lead to missing information in a report when logs are available but not displayed.

When an incident in FortiAnalyzer is identified as a false positive and its status is updated to "Closed: False Positive," certain records and logs are updated to reflect this change.

Option A - The Audit History Log Will Be Updated:

FortiAnalyzer maintains an audit history log that records changes to incidents, including updates to their status. When an incident status is marked as "Closed: False Positive," this action is logged in the audit history to ensure traceability of changes. This log provides accountability and a record of how incidents have been handled over time.

Conclusion:Correct.

Option B - The Corresponding Event Will Be Marked as Mitigated:

Changing an incident to "Closed: False Positive" does not affect the status of the original event itself. Marking an incident as a false positive signifies that it does not represent a real threat, but it does not imply that the event has been mitigated.

Conclusion:Incorrect.

Option C - The Incident Will Be Deleted:

Marking an incident as "Closed: False Positive" does not delete the incident from FortiAnalyzer. Instead, it updates the status to reflect that it is not a real threat, allowing for historical analysis and preventing similar false positives in the future. Deletion would typically only occur manually or by a different administrative action.

Conclusion:Incorrect.

Option D - The Incident Number Will Be Changed:

The incident number is a unique identifier and does not change when the status of the incident is updated. This identifier remains constant throughout the incident's lifecycle for tracking and reference purposes.

Conclusion:Incorrect.

Conclusion:

Correct Answer:A. The audit history log will be updated.

This is the most accurate answer, as the update to "Closed: False Positive" is recorded in FortiAnalyzer’s audit history log for accountability and tracking purposes.

Enablingauto-cachein FortiAnalyzer reports is designed to improve the efficiency and speed of report generation by leveraging cached data. Let’s analyze each option to determine which effects are correct.

Option A - The Generation Time for Reports is Decreased:

When auto-cache is enabled, FortiAnalyzer can use previously cached data instead of reprocessing all log data from scratch each time a report is generated. This results in faster report generation times, especially for recurring reports that use similar datasets.

Conclusion:Correct.

Option B - Hard-Cache Data is Automatically Updated When New Logs are Received:

Enabling auto-cache does not immediately update the cache with every new log received. Instead, the cache is updated when reports are generated, based on the existing logs up to that point. Therefore, auto-cache does not constantly refresh with each incoming log, which would be inefficient.

Conclusion:Incorrect.

Option C - FortiAnalyzer Local Cache is Used to Store Generated Reports:

Auto-cache utilizes FortiAnalyzer’s local cache to store data used in reports, reducing the need to retrieve and process logs repeatedly. This cached data can be reused for subsequent report generation, enhancing performance.

Conclusion:Correct.

Option D - The Size of Newly Generated Reports is Optimized to Conserve Disk Space:

Auto-cache does not directly impact the size of the report files themselves. It focuses on performance optimization through cached data for faster access, but it does not compress or optimize the storage size of the generated report.

Conclusion:Incorrect.

Conclusion:

Correct Answer:A. The generation time for reports is decreasedandC. FortiAnalyzer local cache is used to store generated reports.

Enabling auto-cache helps reduce report generation time by using locally cached data and optimizes report processing, though it does not impact report size or continuously update with each new log.

In this output, we see two diagnostic commands executed on a FortiAnalyzer device:

diagnose fortilogd lograte: This command shows the rate at which logs are being processed by the FortiAnalyzer in terms of log entries per second.

diagnose fortilogd msgrate: This command displays the message rate, or the rate at which individual messages are being processed.

The values provided in the exhibit output show:

Log rate (lograte): Consistently high, showing values such as 70.0, 132.1, and 133.3 logs per second over different time intervals.

Message rate (msgrate): Lower values, around 1.4 to 1.6 messages per second.

Explanation

Interpretation of log rate vs. message rate: In FortiAnalyzer, the log rate typically refers to the rate of logs being stored or indexed, while the message rate refers to individual messages within these logs. Given that a single log entry can contain multiple messages, it's common to see a lower message rate relative to the log rate.

Understanding normal operation: In this case, the message rate being lower than the log rate is expected and typical behavior. This discrepancy can arise because each log entry may bundle multiple related messages, reducing the message rate relative to the log rate.

Conclusion

Correct Answer:A. The message rate being lower than the log rate is normal.

This aligns with the normal operational behavior of FortiAnalyzer in processing logs and messages.

There is no indication that both logs and messages are nearly finished indexing, as that would typically show diminishing rates toward zero, which is not the case here. Additionally, there’s no information in this output about specific ADOMs or a comparison between traffic logs and event logs. Thus, options B, C, and D are incorrect.

FortiAnalyzer has two primary operating modes:Analyzer modeandCollector mode. Each mode serves specific purposes and has distinct capabilities.

Option A - Forwarding Logs to a Syslog Server in Collector Mode:

In Collector mode, FortiAnalyzer collects logs from Fortinet devices but does not process or analyze them. Instead, it forwards the logs to other FortiAnalyzer units in Analyzer mode or to specific storage locations. However, forwarding logs to a syslog server is not a function of Collector mode. Logs are generally stored or sent to other FortiAnalyzer devices.

Conclusion:Incorrect.

Option B - Default Mode is Collector Mode Unless Configured for HA:

When a FortiAnalyzer is initially set up, it runs in Collector mode by default unless it is configured as part of a High Availability (HA) setup, which would set it to Analyzer mode. Collector mode prioritizes log collection and storage rather than analysis, offloading analysis to other devices in the network.

Conclusion:Correct.

Option C - Report Creation and Editing in Collector Mode:

In Collector mode, FortiAnalyzer does not have the capability to create or edit reports. This mode is focused solely on log collection and forwarding, with analysis and report generation left to FortiAnalyzer units operating in Analyzer mode.

Conclusion:Incorrect.

Option D - Performance Improvement with Both Modes in Topology:

Deploying FortiAnalyzer devices in both Collector and Analyzer modes in a network topology can enhance performance. Collector mode devices handle log collection, reducing the workload on Analyzer mode devices, which focus on log processing, analysis, and reporting. This separation of tasks can optimize resource usage and improve the overall efficiency of log management.

Conclusion:Correct.

Conclusion:

Correct Answer:B. FortiAnalyzer runs in collector mode by default unless it is configured for HAandD. A topology with FortiAnalyzer devices running in both modes can improve their performance.

These answers correctly describe the functionality and default configuration of FortiAnalyzer operating modes, along with how a mixed-mode topology can enhance performance.
