23) How can you use store configs?
Ans: The quick utilization of store configs is exported assets. Exported assets are assets that are prefixed by @@. Those assets are checked extraordinarily so they can be gathered on a few different hubs. Some example use cases are:
Share/disseminate open keys (ssh or OpenSSL or different sorts) Build rundown of hosts running a few administrations (for checking) Build arrangement documents that require numerous hosts (for example/and so on/resolve.conf can be the link of records sent out by your DNS cache hosts
24) What do you mean by facter and explain some use cases for the same?
Ans: At some point, you have to compose shows on contingent articulation dependent on conditional expression based data which is accessible through Facter. Facter gives data like Kernel adaptation, Distribution discharge, IP Address, CPU information, and so forth. You can characterize your own custom realities. Facter can be utilized autonomously from Puppet to accumulate data about a framework. Regardless of whether it’s parsing the/proc/xen index on Linux or running prtdiag order on Solaris, the tool works superbly abstracting the particular working framework orders used to decide the collection of facts. At the point when utilized related to Puppet, realities assembled through the framework permits the manikin ace to settle on savvy choices during show gathering.
Inside your manikin show, you can reference any key worth sets given by facter by prefixing the hash key with “$”. If the default set of realities are not adequate, there are two different ways to stretch out Facter to give extra truth. One route is to utilize Ruby, the other path is by utilizing condition factors prefixed with FACTER_. S. This permits one to set for every node data and use it in our shows.

27) What are classes?
Ans: Classes are named squares of Puppet code that are put away in modules for some time in the future and are not applied until they are invoked by name. They can be added to a node’s list by either announcing them in your shows or allocating them from an ENC. Classes for the most part arrange huge or medium-sized lumps of usefulness, for example, the entirety of the bundles, config records, and administrations expected to run an application.
28) How can you test manifest files?
Ans: Clarify how you will initially run linguistic structure checks with manikin parser approval order. In the event that you are utilizing VIM, you can utilize modules like Syntastic to confirm code (or else) utilize a full-fledged IDE like Geppetto. Additionally use puppet build-up to confirm notwithstanding puppet parser. You can add RSpec/cucumber tests to your application. (Be Careful: RUBY aptitudes are required) and use Cucumber in independent mode to test your manifests.
29) Why should you use MCollective over plain vanilla Puppet?
Ans: The Marionette Collective, otherwise called MCollective, is a structure for building server coordination or equal occupation execution frameworks. Most clients automatically execute authoritative assignments on groups of servers. MCollective has some special qualities for working with huge quantities of servers:
Rather than depending on a static rundown of hosts to order, it utilizes metadata-based revelation and sifting. It can utilize a rich information source like PuppetDB or can perform constant disclosure over the system. Rather than legitimately associating with each host (which can be asset serious and moderate), it utilizes distribute/buy-in middleware to impart in corresponding with numerous hosts on the double.

33) Explain Puppet Kick.
Ans: By default, Puppet Agent requests a Puppet Master after a periodic time which is known as “run interval”. Puppet Kick is a utility that allows you to trigger the Puppet Agent from Puppet Master.
34) Differentiate between class definition and class declaration.
Ans: Defining a class makes it accessible for later use. It doesn’t yet add any assets to the index; to do that, you should declare it or assign it from an ENC.
35) Explain ordering and relationship.
Ans: As a matter of course, Puppet applies assets in the request they’re proclaimed in their show. Be that as it may, if a gathering of assets should consistently be overseen in a particular request, you should unequivocally declare such relationships with relationship meta parameters, chaining arrows, and the required function. Puppet utilizes four meta parameters to set up connections, and you can set every one of them as a trait in any asset. The estimation of any relationship meta parameter should be an asset reference (or array of references) highlighting at least one objective asset.
before - Applies an asset before the objective asset requires - Applies an asset after the objective asset notifies - Applies an asset before the objective asset. The objective asset revives if the advising asset changes. subscribe - Applies an asset after the objective asset. The subscribing resource refreshes if the objective asset changes.
If the two assets need to occur altogether, you can either place a preceding characteristic in the earlier one or a required property in the resulting one; either approach makes a similar relationship. The equivalent is valid for notify and subscribe.
36) Explain the design patterns you have used in your Puppet code.
Ans: Here is a tip to answer this question: Be exceptionally clear on this as this tests your development knowledge rather than sysadmin aptitudes. In any event, you will be tested profoundly on job/profile designs – this is the best and most complex way to deal with looking after code. Notice Anchor patterns and clarify why you are utilizing it. You should just utilize this example before Puppet 3.4 or PE 3.2.
37) Explain r10k.
Ans: R10k gives a universally useful toolset to conveying Puppet conditions and modules. It executes the Puppetfile design and gives a local usage of Puppet dynamic situations. R10k has two essential jobs: introducing Puppet modules utilizing an independent Puppetfile, and overseeing Git and SVN based unique conditions
38) What common workflow is used for r10k?
Ans: A great part of the basic work process relies upon the standard git-flow to create highlight branches and rolling out all improvements in include branches, conveying the earth in test mode, and on the confirmation, converging to a branch before tidying up the highlighted branch. On the off chance that you are not utilizing the standard git-flow, receive likewise.
39) Can Puppet run on unique servers?
Ans: Puppet can run on servers that are interesting. Despite the fact that there may be exceptionally fewer odds of servers being special since inside an association there are a ton of likenesses that exist like the working framework that they are running on, etc.
40) Explain the architecture of Puppet.
Ans: Puppet is Open Source programming. It depends on the Client-server design. It is a Model-Driven framework. The customer is likewise called Agent. What’s more, the server is known as the Master. It has the accompanying building parts:
Configuration Language: Puppet gives a language that is utilized to design Resources. We need to indicate what Action must be applied to which Resource. The Action has three things for every Resource: type, title, and rundown of characteristics of an asset. Puppet code is written in Manifests documents.
Resource Abstraction: We can make Resource Abstraction in Puppet with the goal that we can design assets on various stages. The puppet operator utilizes a Factor for passing the data of a domain to the Puppet server. In Fact, we have data about IP, hostname, OS, and so on of the earth.
Transaction: In Puppet, Agent sends Factor to the Master server. Ace sends back the inventory to the Client. The specialist applies any arrangement changes to the framework. When all progressions are applied, the outcome is sent to the Server.
