What's in the title and what's in the certification track? - Cisco Systems - 2021

When I read the "Unofficial" announcement of the new CCNP Wireless, I thought that this is just another area where Cisco, at the moment, is constantly at odds. I joke about it because there are so many classes I teach. In this case, use the "no" command against the "clear" command that you used last. In any case, looking at professional level certificates, you will notice CCNP, CCSP, CCVP, CCIP and probably (based on ads) the new CCNP Wireless network cisco voip certification

Could this be inconsistent because of how close CCWP (I think it should be called) would be to close the acronym to neutral CWNP provider certification? I guess that's the point at this point, and we'll have to wait to see what the official announcement on CiscoLive brings. I still have my opinion on the sequence of compositions. CCENT is the beginning. Then CCNA. With CCNA you can go directly to CCNP, but to make CCSP, CCVP or soon become a Wireless Professional, you must specialize in CCNA, CCNA Security, Voice CCNA or CCNA Wireless. 

I personally would like to see a certain sequence. Allow the CCNA routing and switching required before CCNP to be set. You can focus more on networking solutions, as it applies to Cisco solutions, as well as unified communications, mobility, and security. If you are unfamiliar, the following link shows the solution on the Cisco website. 

Cisco Network Systems Solutions However, if you take a closer look, you'll find products that are detailed in the Network Systems solution, including routers, switches, network management and iOS software. All of this is important for a CCNP candidate because the track focuses on routers, switches, and IOS software functionality. Another key aspect of the associated specialization is that they not only cover Enterprise-class devices that would be ISR routers and local / fixed LAN switches for CCNP, but they also cover devices designed to deploy small branches. 

With CCNA routing and switching, you can cover fast series switches as well as 500 series routers. All are designed as part of the Smart Business communications system. Again, these are my personal thoughts, but anyway I'm going with the tide. I think the Learning @ Cisco people are doing a great job of bringing the curriculum to market, as complete as it is. I look forward to the official announcement on CiscoLive

What are the differences with a patrimonial civil society?

By definition, a patrimonial civil society is a civil society whose corporate purpose is the management and transmission of heritage . This can be in the form of real estate or securities.

The various forms of civil society discussed above have notable differences with what is called a patrimonial civil society or SC Pat.

If a classic SCI allows for example to carry out activities of management of real estate assets, a patrimonial SC makes it possible to extend the corporate object to the management of transferable securities which have a patrimonial character , that is to say , which can be transmitted between associates. The latter can be part of the same family, as in the case of a classic SCI.

Thus, the activities of a patrimonial SC can extend to the following areas : freelance engineering

Sale of real estate with a view to making investments or investments (financial assets, etc.);

Investments in the capital of other companies ;

Transmission of securities and real estate assets within the framework of a succession.

In short, a patrimonial SC is differentiated by the fact that it offers partners the possibility of carrying out other activities in addition to the management of real estate. These activities must however remain in the civil domain . On the other hand, we can say that a SC Pat is similar to a civil holding company .

Procedures and formalities for the creation of a civil society

There are preconditions for the creation of a civil society, and which mainly concern the number of partners , the share capital , the nature of the activities ( corporate purpose ), but also the constitution of funds ( contributions ).

What are the conditions for creating a civil society?

Whatever its legal form (SCI, portfolio SC, property SC, SCCV or even professional SC…), creating a civil society requires a certain number of very specific steps and formalities . Before taking these steps and formalities, discover the various provisions relating to the creation of a civil society:

A civil society is made up of at least two partners ;

The number of partners is not limited , except in the case of a professional civil society whose partners are all physicians, and whose number cannot exceed 8 partners;

The partners can be of different nationalities , and be legal or natural persons ;

A share capital shall consist in the creation of a civil society, but without minimum required;

Each partner must make a contribution which can be either in cash (in money or cash), or in kind (material goods, assets, etc.), or even in industry (knowledge, etc.);

The share capital is divided between the partners in equal shares , and any transfer of shares can only be done with the approval of the majority;

The duration of existence of a civil society cannot exceed 99 years ;

The establishment must have one or more managers who can also be partners;

Each of the managers is representative of the company vis-à-vis third parties or establishments , and if the manager is a legal person, he must have a legal representative to replace him if necessary;

Each partner can decide to withdraw from the structure, partially or totally;

The partners adopt all measures and decisions concerning civil society during general meetings , or following a written vote;

What is Data Engineering?

Using data can help in many things, from personalized marketing campaigns to driving self-driving cars. Data processing specialists are responsible for analyzing the data and using it for various purposes.

However, they need good quality data to perform complex tasks such as predicting business trends. This is where data engineers come in.

Data engineering is the science of collecting and validating information (data) that data scientists can use what does an engineer do.

Role of Data Engineer: -

Data Engineers are the people who create the information infrastructure on which data science projects depend. These professionals are responsible for designing and managing data flows that combine information from various sources into a common pool (such as a data warehouse) from which it can be retrieved for analysis by data scientists and business intelligence analysts. Typically this involves implementing data pipelines based on some form of ETL model (extract, transform, and load) .

To create this information architecture, data engineers rely on a variety of programming and data management tools to implement ETL, manage relational and non-relational databases, and build data warehouses. Let's take a quick look at some of the most popular tools.

Data Engineering Tools: -

Pace Hadoop is the fundamental data engineering foundation for storing and analyzing large amounts of information in a distributed processing environment. Hadoop is not a single unit, but a set of open source tools such as HDFS (Hadoop Distributed File System) and MapReduce distributed processing engine.

Pace Spark is a Hadoop-compatible data processing platform that, unlike MapReduce, can be used for real-time stream processing as well as batch processing. He was almost in 100 times faster than the MapReduce, and seems to displace it in the Hadoop ecosystem. Spark offers APIs for Python, Java, Scala, and R, and can run as a stand-alone platform independent of Hadoop.

Pache Kafka is the most widely used data collection and food intake tool today. Kafka is an easy to configure and use high performance platform that can transfer large amounts of data very quickly to a target such as Hadoop.

Apache Cassandra is widely used to manage large amounts of data with lower latency for users and automatic replication to multiple sites for fault tolerance.

S QL and NoSQL (relational and non-relational databases) are fundamental tools for data engineering applications. Historically, relational databases like DB2 or Oracle have been the standard. But with today's applications increasingly processing huge amounts of unstructured, semi-structured, and even polymorphic data in real time, non-relational databases are now coming into their own.
