Discuss Splunk SPLK-1003 Exam Topic 13 Question 92

On the deployment server, administrators can map clients to server classes using client filters. Which of the

following statements is accurate?

AThe blacklist takes precedence over the whitelist.

BThe whitelist takes precedence over the blacklist.

CWildcards are not supported in any client filters.

DMachine type filters are applied before the whitelist and blacklist.

Suggested Answer: C

The correct answer is C. MonitorNoHandle.

MonitorNoHandle is a type of input stanza that allows a Splunk forwarder to read files on Windows systems as Windows writes to them. It does this by using a kernel-mode filter driver to capture raw data as it gets written to the file1. This input stanza is useful for files that get locked open for writing, such as the Windows DNS server log file2.

The other options are incorrect because:

A) Tail Reader is not a valid input stanza in Splunk. It is a component of the Tailing Processor, which is responsible for monitoring files and directories for new data3.

B) Upload is a type of input stanza that allows Splunk to index a single file from a local or network file system. It is not suitable for files that are constantly being updated, as it only indexes the file once and does not monitor it for changes4.

D) Monitor is a type of input stanza that allows Splunk to monitor files and directories for new data. However, it may not work for files that Windows prevents Splunk from reading while they are open. In such cases, MonitorNoHandle is a better option2.

A Splunk forwarder is a lightweight agent that can forward data to a Splunk deployment. There are two types of forwarders: universal and heavy. A universal forwarder can only forward data, while a heavy forwarder can also perform parsing, filtering, routing, and aggregation on the data before forwarding it5.

An input stanza is a section in the inputs.conf configuration file that defines the settings for a specific type of input, such as files, directories, network ports, scripts, or Windows event logs. An input stanza starts with a square bracket, followed by the input type and the input path or name. For example, [monitor:///var/log] is an input stanza for monitoring the /var/log directory.

Just to clarify, A is the standard practice in most setups.

Rozella 11 months ago

Wait, are you sure about D? That seems off to me.

Beth 11 months ago

Wildcards are definitely supported in client filters, so C is wrong.

Reita 11 months ago

I thought it was the other way around, B makes more sense to me.

Portia 11 months ago

A is correct, blacklist does take precedence.

Onita 12 months ago

I vaguely remember that machine type filters come into play before the other filters, but I need to double-check that.

Emilio 12 months ago

I feel like wildcards were mentioned in our study materials, but I can't recall if they were supported in client filters or not.

Maryanne 12 months ago

I practiced a similar question last week, and I think the whitelist usually takes priority in these scenarios.

Gilberto 1 year ago

I remember something about whitelists and blacklists, but I'm not sure which one takes precedence. I think it might be the blacklist?

Lisha 1 year ago

I feel pretty confident about this one. The order of precedence between the filters is the key to answering correctly.

Gary 1 year ago

Wildcards not being supported in any client filters? That's an interesting detail I'll need to keep in mind.

Lashaunda 1 year ago

Hmm, I'm a bit unsure about the relationship between the whitelist and blacklist. I'll need to think this through carefully.

Herminia 1 year ago

This question seems straightforward, but I want to make sure I understand the concepts of whitelists and blacklists before answering.

Goldie 1 year ago

Okay, I think I've got this. The key is understanding the order of precedence between the different client filters.

Christoper 1 year ago

Based on the details provided, I would say the best option is "Scheduled update". The bank wants to share new contact details, which seems more like a routine update rather than an urgent priority communication.

Yasuko 1 year ago

I'm leaning towards forward-time; it sounds familiar related to the timing, but I'm still hesitant about it.

The blacklist taking precedence over the whitelist? That's just asking for trouble! I'll have to go with B.

↳ replying to Natalya

It's important to understand the order in which filters are applied to avoid any conflicts. B does seem like the logical choice here.

Twanna 1 year ago

↳ replying to Natalya

I've had issues in the past with client filters, so I always make sure to double check. B does make sense to me.

Gearldine 1 year ago

↳ replying to Natalya

I think we should be careful with our client filters to avoid any issues. B does seem like the safer option.

Lucina 1 year ago

↳ replying to Natalya

I agree, having the blacklist take precedence seems risky. I also think B is the correct answer.
