Q. How well can you explain the Active Directory concept in the System administration?
When it comes to network security and administration, something that largely matters is nothing but the centralized control of everything. The same can easily be assured through the Active Directory. The nodes which are associated with the server are generally configured with the Active Directory. Generally, they act as controllers for all the domains concerned with the network. All the settings and the information related to the development is generally stored in the central database. The Directory makes sure that the administrators to enable the deployment and policies. Depending upon the nature of the task, it is also responsible for the other tasks that are related to the operating system.

OpenStack Tutorial
The main objective of OpenStack course is to produce ubiquitous opensource cloud computing platform which would meet the needs of public as well as private cloud providers. OpenStack is an open source project which accepts all the hyper-visors as virtualization host, Object storage , Software defined networking , Orchestration and many more.
This particular OpenStack tutorial gives an overview of OpenStack and its various components.
OpenStack has a very modular design, and because of this design, there are lots of moving parts. It’s overwhelming to start walking through installing and using OpenStack without understanding the internal architecture of the components that make up. OpenStack manages a different resource that can be virtualized for the end user. Separating each of the resources that can be virtualized into separate components makes the OpenStack architecture very modular. If a particular service or resource provided by a component is not required, then the component is optional to an OpenStack deployment. Let’s start by outlining some simple categories to group these services into.

OpenStack’s architecture
Logically, the components of OpenStack Training can be divided into three groups:
1. Control
2. Network
3. Compute
The control tier runs the Application Programming Interfaces (API) services, web interface, database and message bus. The network tier runs network service agents for networking and compute node is the virtualization hypervisor. It has services and agents to handle virtual machines. All of the components use a database and/ or a message buses can be MySQL, MariaDB, or PostagreSQL. The most popular message buses are RagbbitMQ, Qpid, and ActiveMQ. For smaller deployments, the database and messaging services usually run on the control node, but they could have their own nodes if required.

In a simple multi-node deployment, each of these groups is installed onto a separate server. OpenStack could be installed on one node or two nodes, but a good baseline for being able to scale out later is to put each of these groups on their own node. An OpenStack cluster can also scale far beyond these nodes, and we’ll look at scaling beyond this basic deployment in Chapter 11 scaling Horizontally.
The OpenStack project is an open source cloud computing platform for all types of clouds, which aims to be simple to implement, massively scalable, and feature rich. Developers and cloud computing technologists from around the world create the OpenStack project.

Monitoring the node installation and Using Chef to Install OpenStack
Once you have created and enabled the policy, nodes will begin to install. This may or may not take a long time depending on the size of your system. Razor provides a basic set of monitoring commands so you can tell when nodes have finished installing.
Getting started
Log into the razor node and sudo to root.
vagrant ssh razor sudo su -
How to achieve it…
To monitor the install progress of a node, execute the following command:
watch razor active_model logview
How it works…
The razor active_model logview command will report on the activity of nodes as they progress through the various stages of an installation. You will know your first node has finished when you see “Broker Success”.
Using Chef to install OpenStack
At this stage, we have a node with Ubuntu 12.04 installed by RAZOR. Additionally, that node has the 11.4.4 installed. At this stage, we need to tell Chef that this node will be an “all in one”, for example, that it will run Keystone, Nova Compute, Horizon, Glance, and a number of other services.
Getting ready
To install OpenStack on to our node, log into the Chef Server as root:
vagrant ssh chef sudo su -
How to do it…
To tell Chef that our node is an all in one, execute the following command:
EDITOR=vim knife node edit node1.cook.book
Change the following line:
"chef_environment": "cookbook",
Add these lines:
"run_list": [ "role[allinone]" ]
Then exit vim with ‘:wq’.
Next log into the node and execute: chef-client.
Next log into the node and execute: chef-client.
How it works…
Once logged into the Chef Server, we modified the definition of the node to place it into our OpenStack environment. Additionally, we assigned the node the “all in one” role, which contains all of the other roles and services necessary to build a self contained OpenStack environment. Finally, we execute CHEF-CLIENT, which pushes everything into motion.

Introduction to ReactJS
Overview of ReactJS:
React.js is a JavaScript library developed by Facebook. React is a library for building composable UIs. It empowers the creation of reusable UI segments which present data that changes over time. Many people make use of React as the V in MVC. React abstracts away the DOM from you, resulting in a complex programming model and better execution. React can also render on the server using Node, and it can power local apps using React Native. React actualizes one-way reactive data stream which reduces standard and is easier to reason about than traditional data binding.
Why do people choose to program with React?
Fast - Feel quick and responsive through the Apps made in React can handle complex updates.
Modular - Allow you to write many smaller, reusable files, instead of writing large, dense files of code. Modularity of React is a beautiful solution for JavaScript's visibility issues.
Scalable - React performs best in case of large programs that display a lot of data changes.
Flexible - React approaches differently by breaking them into components while building user interfaces. This is incredibly important in large applications.
Popular - ReactJS gives better performance than other JavaScript languages due to t’s implementation of a virtual DOM.

1. JSX − JSX is a preferable choice for many web developers. It isn't necessary to use JSX in React development, but there is a huge difference between writing react.js documents in JSX and in JavaScript.
2. Unidirectional data flow and Flux − React.js is designed in such a manner that it will only support data that is flowing downstream, in one direction. If the data has to flow in another direction, you will need additional features.
3. Components − Components are the heart and soul of React. Components (like JavaScript functions) let you split the UI into independent, reusable pieces, and think about each piece in isolation.

React Advantages:
- React.js creates its own virtual DOM. This will improve apps performance since JavaScript virtual DOM is faster than the regular DOM.
- ReactJS helps to create awesome UIs.
- Awesome for SEO - Generally have trouble in reading Javascript, React.js stands out from the crowd as you can run React.js on the server.
- Component and Data patterns improve readability which helps to maintain larger apps.
- React can be used with other frameworks.

According to research SCCM has a market share of about 7.6%. So, You still have opportunity to move ahead in your career in SCCM Tutorial. Mindmajix offers advanced SCCM Interview Questions 2018 that helps you in cracking your interview & acquire dream career as SCCM Developer.
Q1) Difference Between SCCM & WSUS?
| SCCM Vs WSUS | |
| SCCM | WSUS |
| It is an Enterprise Management sys for which encompassing | It is a patching solution so it does only one thing |
| It is used for pushing images of all types of OS's | It cannot be used for pushing images for OS's |
| It includes asset management | It does not include asset management |
| It pushes out's apps other than windows update | It cannot push out apps |
| Outside Patching SCCM includes: Operating Sys Deployment, App Installation, Config Management | It does Uses SCCM |
| WithIn Patching SCCM provides: Detailed reporting, 3rd party patching supporting. | It uses to manage 3rd party & create a huge amount of work |
Q2) What is SCCM?
System center configuration manager (CM12 or CM07 or ConfigMgr or Configuration Manager), formerly Systems Management Server (SMS), is a systems management software product by Microsoft for managing large groups of Windows-based computer systems. Configuration Manager provides remote control, patch management, software distribution, operating system deployment, network access protection, and hardware and software inventory.
Q3) What is SMS Provider?
The SMS Provider is a WMI provider that allows both read and write access to the Networking Configuration Manager 2007 site database. The SMS Provider is used by the Configuration Manager console
The SMS Provider can be installed on the site database server computer, site server computer or another server class third computer during Configuration Manager 2007 Setup. After setup has completed, the current installed location of the SMS Provider is displayed on the site properties general tab
Q4) What is ITMU?
SMS 2003 Inventory Tool for Microsoft Updates
Q5) What is the use of WSUS (Windows Server Update Service)?
It enables administrators to deploy the latest Microsoft product updates to computers that are running the Windows operating system.
Q6) Can you assign clients to a secondary site?
No. If you have a secondary site, the client must be assigned to the primary parent of the secondary site. However, Configuration Manager knows how to manage clients at the child secondary site. If there is a distribution point at the secondary site that has the content the clients need, the clients will probably get the content from the local distribution point instead of crossing the WAN link to the primary site.
Q7) Can Configuration Manager 2007 be used to package software for distribution?
No. Configuration Manager 2007 delivers command lines to clients and can force those command lines to run with administrative rights using the Local System account. Configuration Manager 2007 command lines can be batch files, scripts, Windows Installer files with .msi extensions, executable files – any file that the operating system can run, Configuration Manager 2007 can distribute. However, Configuration Manager 2007 does not actually package any software for distribution.
Q8) Can computers show up in the Configuration Manager console before they have the Configuration Manager client installed?
Yes. If you use a discovery method, Configuration Manager can find many resources and create data discovery records (DDRs) for them, and those DDRs are stored in the database. However, you cannot use Configuration Manager features such as software distribution, software updates management, and inventory until you install the client components.
Q9) Can a site have more than one default management point?
No. You can configure more than one management points in a site, but only one of those management points can be configured as the default management point to support intranet clients in the site. If you are concerned about performance, you can configure more than one management point, configure them to be part of a Network Load Balancing (NLB) cluster, and them configure the NLB cluster as the default management point.
Q10) Can a secondary site have child sites?
No. A secondary site cannot have a primary or secondary site reporting to it. Secondary sites are always child sites to a primary site.
Q11) Can you install the Configuration Manager Client components without discovering the computer first?
Yes. Client Push Installation is the only client installation method that requires clients to be discovered first.
