質問 # 67
When should multiple search pipelines be enabled?

• A. Only if running Splunk Enterprise version 6.6 or later.
• B. Only if disk IOPS is at 800 or better.
• C. Only if there are fewer than twelve concurrent users.
• D. Only if CPU and memory resources are significantly under-utilized.

正解：D

解説：
Explanation
Multiple search pipelines should be enabled only if CPU and memory resources are significantly under-utilized. Search pipelines are the processes that execute search commands and return results. Multiple search pipelines can improve the search performance by running concurrent searches in parallel. However, multiple search pipelines also consume more CPU and memory resources, which can affect the overall system performance. Therefore, multiple search pipelines should be enabled only if there are enough CPU and memory resources available, and if the system is not bottlenecked by disk I/O or network bandwidth. The number of concurrent users, the disk IOPS, and the Splunk Enterprise version are not relevant factors for enabling multiple search pipelines

質問 # 70
Which search head cluster component is responsible for pushing knowledge bundles to search peers, replicating configuration changes to search head cluster members, and scheduling jobs across the search head cluster?

• A. Master
• B. Captain
• C. Deployment server
• D. Deployer

正解：B

解説：
The captain is the search head cluster component that is responsible for pushing knowledge bundles to search peers, replicating configuration changes to search head cluster members, and scheduling jobs across the search head cluster. The captain is elected from among the search head cluster members and performs these tasks in addition to serving search requests. The master is the indexer cluster component that is responsible for managing the replication and availability of data across the peer nodes. The deployer is the standalone instance that is responsible for distributing apps and other configurations to the search head cluster members. The deployment server is the instance that is responsible for distributing apps and other configurations to the deployment clients, such as forwarders

質問 # 71
What is the logical first step when starting a deployment plan?

• A. Inventory the currently deployed logging infrastructure.
• B. Collect the initial requirements for the deployment from all stakeholders.
• C. Determine what apps and use cases will be implemented.
• D. Gather statistics on the expected adoption of Splunk for sizing.

正解：B

解説：
Explanation
The logical first step when starting a deployment plan is to collect the initial requirements for the deployment from all stakeholders. This includes identifying the business objectives, the data sources, the use cases, the security and compliance needs, the scalability and availability expectations, and the budget and timeline constraints. Collecting the initial requirements helps to define the scope and the goals of the deployment, and to align the expectations of all the parties involved.
Inventorying the currently deployed logging infrastructure, determining what apps and use cases will be implemented, and gathering statistics on the expected adoption of Splunk for sizing are all important steps in the deployment planning process, but they are not the logical first step. These steps can be done after collecting the initial requirements, as they depend on the information gathered from the stakeholders.

質問 # 75
The frequency in which a deployment client contacts the deployment server is controlled by what?

• A. polling_interval attribute in deploymentclient.conf
• B. phoneHomeIntervalInSecs attribute in deploymentclient.conf
• C. phoneHomeIntervalInSecs attribute in outputs.conf
• D. polling_interval attribute in outputs.conf

正解：B

解説：
Explanation
The frequency in which a deployment client contacts the deployment server is controlled by the phoneHomeIntervalInSecs attribute in deploymentclient.conf. This attribute specifies how often the deployment client checks in with the deployment server to get updates on the apps and configurations that it should receive. The polling_interval attribute in outputs.conf controls how often the forwarder sends data to the indexer or another forwarder. The polling_interval attribute in deploymentclient.conf and the phoneHomeIntervalInSecs attribute in outputs.conf are not valid Splunk attributes. For more information, see Configure deployment clients and Configure forwarders with outputs.conf in the Splunk documentation.

質問 # 76
To activate replication for an index in an indexer cluster, what attribute must be configured in indexes.conf on all peer nodes?

• A. replicate = auto
• B. replicate = 0
• C. repFactor = 0
• D. repFactor = auto

正解：D

解説：
To activate replication for an index in an indexer cluster, the repFactor attribute must be configured in indexes.conf on all peer nodes. This attribute specifies the replication factor for the index, which determines how many copies of raw data are maintained by the cluster. Setting the repFactor attribute to auto will enable replication for the index. The replicate attribute in indexes.conf is not a valid Splunk attribute. The repFactor attribute in outputs.conf and the replicate attribute in deploymentclient.conf are not related to replication for an index in an indexer cluster. For more information, see Configure indexes for indexer clusters in the Splunk documentation.

質問 # 77
When designing the number and size of indexes, which of the following considerations should be applied?

• A. Data retention time policies, number of installed apps, access controls
• B. Number of installed apps, expected daily ingest volume, data retention time policies
• C. Expected daily ingest volumes, data retention time policies, access controls
• D. Expected daily ingest volume, access controls, number of concurrent users

正解：C

解説：
When designing the number and size of indexes, the following considerations should be applied:
* Expected daily ingest volumes: This is the amount of data that will be ingested and indexed by the Splunk platform per day. This affects the storage capacity, the indexing performance, and the license usage of the Splunk deployment. The number and size of indexes should be planned according to the expected daily ingest volumes, as well as the peak ingest volumes, to ensure that the Splunk deployment can handle the data load and meet the business requirements12.
* Data retention time policies: This is the duration for which the data will be stored and searchable by the Splunk platform. This affects the storage capacity, the data availability, and the data compliance of the Splunk deployment. The number and size of indexes should be planned according to the data retention time policies, as well as the data lifecycle, to ensure that the Splunk deployment can retain the data for the desired period and meet the legal or regulatory obligations13.
* Access controls: This is the mechanism for granting or restricting access to the data by the Splunk users or roles. This affects the data security, the data privacy, and the data governance of the Splunk deployment. The number and size of indexes should be planned according to the access controls, as well as the data sensitivity, to ensure that the Splunk deployment can protect the data from unauthorized or inappropriate access and meet the ethical or organizational standards14.
Option D is the correct answer because it reflects the most relevant and important considerations for designing the number and size of indexes. Option A is incorrect because the number of concurrent users is not a direct factor for designing the number and size of indexes, but rather a factor for designing the search head capacity and the search head clustering configuration5. Option B is incorrect because the number of installed apps is not a direct factor for designing the number and size of indexes, but rather a factor for designing the app compatibility and the app performance. Option C is incorrect because it omits the expected daily ingest volumes, which is a crucial factor for designing the number and size of indexes.

質問 # 78
What is the expected minimum amount of storage required for data across an indexer cluster with the following input and parameters?
* Raw data = 15 GB per day
* Index files = 35 GB per day
* Replication Factor (RF) = 2
* Search Factor (SF) = 2

• A. 100 GB per day
• B. 50 GB per day
• C. 85 GB per day
• D. 65 GB per day

正解：A

解説：
The correct answer is C. 100 GB per day. This is the expected minimum amount of storage required for data across an indexer cluster with the given input and parameters. The storage requirement can be calculated by adding the raw data size and the index files size, and then multiplying by the Replication Factor and the Search Factor1. In this case, the calculation is:
(15 GB + 35 GB) x 2 x 2 = 100 GB
The Replication Factor is the number of copies of each bucket that the cluster maintains across the set of peer nodes2. The Search Factor is the number of searchable copies of each bucket that the cluster maintains across the set of peer nodes3. Both factors affect the storage requirement, as they determine how many copies of the data are stored and searchable on the indexers. The other options are not correct, as they do not match the result of the calculation. Therefore, option C is the correct answer, and options A, B, and D are incorrect.
1: Estimate storage requirements 2: About indexer clusters and index replication 3: Configure the search factor

質問 # 79
In search head clustering, which of the following methods can you use to transfer captaincy to a different member? (Select all that apply.)

• A. Run the splunk transfer shcluster-captain command from the member you would like to become the captain.
• B. Run the splunk transfer shcluster-captain command from the current captain.
• C. Use the Monitoring Console.
• D. Use the Search Head Clustering settings menu from Splunk Web on any member.

正解：A、D

解説：
Explanation
In search head clustering, there are two methods to transfer captaincy to a different member. One method is to use the Search Head Clustering settings menu from Splunk Web on any member. This method allows the user to select a specific member to become the new captain, or to let Splunk choose the best candidate. The other method is to run the splunk transfer shcluster-captain command from the member that the user wants to become the new captain. This method requires the user to know the name of the target member and to have access to the CLI of that member. Using the Monitoring Console is not a method to transfer captaincy, because the Monitoring Console does not have the option to change the captain. Running the splunk transfer shcluster-captain command from the current captain is not a method to transfer captaincy, because this command will fail with an error message

質問 # 80
When should a dedicated deployment server be used?

• A. When there are more than 50 apps to deploy to deployment clients.
• B. When there are more than 50 server classes.
• C. When there are more than 50 search peers.
• D. When there are more than 50 deployment clients.

正解：D

解説：
A dedicated deployment server is a Splunk instance that manages the distribution of configuration updates and apps to a set of deployment clients, such as forwarders, indexers, or search heads. A dedicated deployment server should be used when there are more than 50 deployment clients, because this number exceeds the recommended limit for a non-dedicated deployment server. A non-dedicated deployment server is a Splunk instance that also performs other roles, such as indexing or searching. Using a dedicated deployment server can improve the performance, scalability, and reliability of the deployment process. Option C is the correct answer. Option A is incorrect because the number of search peers does not affect the need for a dedicated deployment server. Search peers are indexers that participate in a distributed search. Option B is incorrect because the number of apps to deploy does not affect the need for a dedicated deployment server. Apps are packages of configurations and assets that provide specific functionality or views in Splunk. Option D is incorrect because the number of server classes does not affect the need for a dedicated deployment server. Server classes are logical groups of deployment clients that share the same configuration updates and apps12

質問 # 81
Which index-time props.conf attributes impact indexing performance? (Select all that apply.)

• A. ANNOTATE_PUNCT
• B. REPORT
• C. LINE_BREAKER
• D. SHOULD_LINEMERGE

正解：C、D

解説：
Explanation
The index-time props.conf attributes that impact indexing performance are LINE_BREAKER and SHOULD_LINEMERGE. These attributes determine how Splunk breaks the incoming data into events and whether it merges multiple events into one. These operations can affect the indexing speed and the disk space consumption. The REPORT attribute does not impact indexing performance, as it is used to apply transforms at search time. The ANNOTATE_PUNCT attribute does not impact indexing performance, as it is used to add punctuation metadata to events at search time. For more information, see [About props.conf and transforms.conf] in the Splunk documentation.

質問 # 82
Which of the following is a good practice for a search head cluster deployer?

• A. The deployer only distributes configurations to search head cluster members when they "phone home".
• B. The deployer must distribute configurations to search head cluster members to be valid configurations.
• C. The deployer only distributes configurations to search head cluster members with splunk apply shcluster-bundle.
• D. The deployer must be used to distribute non-replicable configurations to search head cluster members.

正解：D

解説：
Explanation
The following is a good practice for a search head cluster deployer: The deployer must be used to distribute non-replicable configurations to search head cluster members. Non-replicable configurations are the configurations that are not replicated by the search factor, such as the apps and the server.conf settings. The deployer is the Splunk server role that distributes these configurations to the search head cluster members, ensuring that they have the same configuration. The deployer does not only distribute configurations to search head cluster members when they "phone home", as this would cause configuration inconsistencies and delays.
The deployer does not distribute configurations to search head cluster members to be valid configurations, as this implies that the configurations are invalid without the deployer. The deployer does not only distribute configurations to search head cluster members with splunk apply shcluster-bundle, as this would require manual intervention by the administrator. For more information, see Use the deployer to distribute apps and configuration updates in the Splunk documentation.

質問 # 83
Which of the following tasks should the architect perform when building a deployment plan? (Select all that
apply.)

• A. Review network topology.
• B. Install Splunk apps.
• C. Use case checklist.
• D. Inventory data sources.

正解：A

質問 # 84
Which of the following are client filters available in serverclass.conf? (Select all that apply.)

• A. IP address.
• B. Splunk server role.
• C. DNS name.
• D. Platform (machine type).

正解：A、C、D

解説：
Explanation
The client filters available in serverclass.conf are DNS name, IP address, and platform (machine type). These filters allow the administrator to specify which forwarders belong to a server class and receive the apps and configurations from the deployment server. The Splunk server role is not a valid client filter in serverclass.conf, as it is not a property of the forwarder. For more information, see [Use forwarder management filters] in the Splunk documentation.

質問 # 86
Which of the following statements describe search head clustering? (Select all that apply.)

• A. A deployer is required.
• B. The deployer must have sufficient CPU and network resources to process service requests and push configurations.
• C. Search heads must meet the high-performance reference server requirements.
• D. At least three search heads are needed.

正解：A、B、D

解説：
Search head clustering is a Splunk feature that allows a group of search heads to share configurations, apps, and knowledge objects, and to provide high availability and scalability for searching. Search head clustering has the following characteristics:
* A deployer is required. A deployer is a Splunk instance that distributes the configurations and apps to the members of the search head cluster. The deployer is not a member of the cluster, but a separate instance that communicates with the cluster master.
* At least three search heads are needed. A search head cluster must have at least three search heads to form a quorum and to ensure high availability. If the cluster has less than three search heads, it cannot function properly and will enter a degraded mode.
* The deployer must have sufficient CPU and network resources to process service requests and push
* configurations. The deployer is responsible for handling the requests from the cluster master and the cluster members, and for pushing the configurations and apps to the cluster members. Therefore, the deployer must have enough CPU and network resources to perform these tasks efficiently and reliably.
Search heads do not need to meet the high-performance reference server requirements, as this is not a mandatory condition for search head clustering. The high-performance reference server requirements are only recommended for optimal performance and scalability of Splunk deployments, but they are not enforced by Splunk.

質問 # 87
Which of the following is a good practice for a search head cluster deployer?

• A. The deployer only distributes configurations to search head cluster members when they "phone home".
• B. The deployer must distribute configurations to search head cluster members to be valid configurations.
• C. The deployer only distributes configurations to search head cluster members with splunk apply shcluster-bundle.
• D. The deployer must be used to distribute non-replicable configurations to search head cluster members.

正解：D

解説：
The following is a good practice for a search head cluster deployer: The deployer must be used to distribute non-replicable configurations to search head cluster members. Non-replicable configurations are the configurations that are not replicated by the search factor, such as the apps and the server.conf settings. The deployer is the Splunk server role that distributes these configurations to the search head cluster members, ensuring that they have the same configuration. The deployer does not only distribute configurations to search head cluster members when they "phone home", as this would cause configuration inconsistencies and delays.
The deployer does not distribute configurations to search head cluster members to be valid configurations, as this implies that the configurations are invalid without the deployer. The deployer does not only distribute configurations to search head cluster members with splunk apply shcluster-bundle, as this would require manual intervention by the administrator. For more information, see Use the deployer to distribute apps and configuration updates in the Splunk documentation.
