The Auto Deployment feature of Distributed Configuration Management is a tool that allows you to automatically distribute configuration files, such as indexes.conf, to your Splunk platform instances. However, using this feature to distribute indexes.conf can pose a risk of having indexes with different settings across your instances. This can happen if you have manually edited the indexes.conf file on some of your instances, or if you have different versions of Splunk Enterprise Security installed on different instances. If the indexes have different settings, such as retention policies, storage paths, or bucket sizes, this can cause data inconsistency, search inefficiency, or data loss. Therefore, it is recommended to use the Manual Deployment feature of Distributed Configuration Management to review and validate the indexes.conf file before deploying it to your instances12. References = 1: Distributed Configuration Management - Splunk Documentation - Auto Deployment. 2: Distributed Configuration Management - Splunk Documentation - Manual Deployment.

According to the Splunk Enterprise Security documentation, one of the actions that may be necessary before installing ES is to redirect distributed search connections. This action is required if you are installing ES on a search head that is already connected to a distributed search environment, such as a search head cluster or a search head pool. You need to redirect the distributed search connections from the existing search head to a new search head that will run ES. This is because ES requires a dedicated search head that is not shared with other apps or users. You can use the Distributed Configuration Management tool to redirect the distributed search connections and create a Splunk Enterprise Security app for indexers. See Redirect distributed search connections for more details.

The other actions are not necessary before installing ES, but they may be helpful for optimizing the performance and scalability of ES. Purging KV Store can free up some disk space and remove stale data, but it is not required before installing ES. See Purge the KV Store for more information. Adding additional indexers can improve the indexing and searching capacity of ES, but it is not required before installing ES. See Deployment planning for more information. Adding additional forwarders can increase the data ingestion and forwarding capability of ES, but it is not required before installing ES. See Forward data to Splunk Enterprise Security for more information. References =

The priority column in the asset or identity list is combined with the event severity to make a notable event’s urgency in Splunk Enterprise Security. The urgency is a measure of how important it is to address a notable event, and it is calculated based on a matrix that maps the priority of the asset or identity involved in the event and the severity of the event. The urgency can be one of the following values: low, medium, high, or critical12. For example, by default, medium, high, and critical priority, combined with critical severity, will generate a critical urgency ranking3. References = 1: Incident Review - Splunk Documentation - Urgency. 2: Configure notable event urgency - Splunk Documentation. 3: Solved: Splunk Enterprise Security: Is there a way to forc… - Splunk Community.

When exporting and importing updates to ES content, you should follow the best practices described in the Splunk Enterprise Security Admin documentation1. One of the best practices is to avoid overwriting existing content on the destination system. To do this, you have two options: either use new app names each time you export content, or always include both existing and new content in each export. This way, you can preserve the original content and avoid conflicts or data loss. The other options, A, B, and C, are not correct. Using new app names each time content is exported is only one of the options, not the only one. Using the .spl extension when naming an export is not a problem, as it is the default extension for Splunk apps. Including only new content for each export is not a good practice, as it may overwrite existing content on the destination system. References =

Threat intel is the lookup type in Enterprise Security that contains information about known hostile IP addresses, as well as other indicators of compromise (IOCs) such as domains, URLs, hashes, and email addresses. Threat intel is collected from various sources, such as Splunk Enterprise Security, Splunk Add-on for Enterprise Security, Splunk Enterprise Security Content Update, and third-party threat intelligence providers. Threat intel is used to enrich events and generate notable events when a match is found between an IOC and an event field. You can view and manage the threat intel sources and lookups in Enterprise Security using the Threat Intelligence framework. References =

 To add a new column to the Notable Event table in the Incident Review dashboard, you need to follow these steps:

On the Splunk Enterprise Security menu bar, click Configure > Incident Management > Incident Review Settings.

On the Incident Review Settings page, click the Table Attributes tab.

On the Table Attributes tab, click Add New Attribute.

Enter the name of the attribute that you want to add as a column, such as src or dest. The name must match the field name in the notable event data model.

Enter a label for the attribute that will appear as the column header, such as Source or Destination.

Enter a description for the attribute that will appear as a tooltip when you hover over the column header.

Select the data type for the attribute, such as string or number.

Select the visibility for the attribute, such as visible or hidden.

Click Save to save the new attribute.

Refresh the Incident Review dashboard to see the new column in the Notable Event table. References =

According to the Splunk Reference Architecture document1, for ES, Splunk recommends sizing based on 80 to 100 GB ingest per indexer per day. This means an ES deployment with 2 TB daily ingest will require up to 20 indexers. This recommendation is for a non-cloud (on-prem) ES deployment. For a cloud-based ES deployment, the recommended volume of indexing per day, per indexer, is 50 GB2. The other options, 300 GB and 500 MB, are not recommended by Splunk for ES deployments. References =

According to the Splunk Enterprise Security documentation, the HTTP Category Analysis dashboard is one of the Web Intelligence dashboards that help you analyze web traffic in your network and identify notable HTTP categories, user agents, new domains, and long URLs. The dashboard shows the top HTTP categories by bytes, requests, and users, and allows you to filter the data by time range, category, user, and domain. The dashboard also provides drilldown links to other dashboards, such as the Web User Agent Analysis dashboard and the Web Domain Analysis dashboard, for further analysis. Therefore, the correct answer is C. HTTP Category Analysis. References = Web Intelligence dashboards.
