Which CCNA Certification Exam is Good to Start First?

As we all know that CCNA is an entry-level certificate that will lead to other certifications like CCNA Security, CCNP R&S, and many others. CCENT/CCNA R&S is a pre-requisite for all the other CCNA “specializations”, but there is no pre-requisite required for preparing CCNA Routing and Switching. If you are new to networking, CCNA is a little tough exam, but not for who have hands-on experience. There are many new concepts to grasp. It is recommended to take two exams i.e. CCENT and ICND2 if you are starting off as a fresher.

The CCNA course focuses on Networking which includes how to plan, create, manage, and troubleshoot a network. CCNA covers the basic knowledge of IP protocols, LAN Switching TechnologiesWAN Technologies, Routing Technologies, and other concepts. CCNA is globally accepted certification and one can expect better career prospects after achieving the certification.

In CCNA exam there will be around 50–60 questions with a time span of 90 minutes. The question types include multiple-choice questions, drag and drop type questions, and simulations. CCNA exam is available in two languages like English and Japanese.

What are the Benefits of CCNA Certification?

  • By preparing for CCNA R&S certification you are going to increase you are knowledge and also it keeps you active in the latest trends of networking
  • Chance of getting promoted is easy with a good hike.
  • CCNA Certification helps in stable employment in the reputed IT firms
  • Even non-technical background candidate can become a CCNA certified by clearing the examination.

Update for Cisco CCNA Routing and Switching Program:

On February 24, 2020, Cisco is going to make changes for CCNA Routing and Switching exam. The new exam covers networking and security fundamentals, as well as automation and programmability. Previously candidate has to take multiple exams to get CCNA certificate, now you have to take only one exam (200–301) to get new CCNA.

The new CCNA will replace the following certifications:

  • CCNA Cloud
  • CCNA Collaboration
  • CCNA Data Center
  • CCDA
  • CCNA Industrial
  • CCNA Routing and Switching
  • CCNA Security
  • CCNA Service Provider
  • CCNA Wireless

If you are already started preparing for CCNA/CCDA keep going and complete the exam before 23 Feb 2020. If you complete the current CCNA/CCDA before the date you’ll receive the new CCNA certification and a training badge in the corresponding technology area.

Network Address Translation – Concepts and Application

Network Address Translation (NAT) is a method of mapping one IP address space into another by modifying network address information in the IP header of packets while they are in transit. i.e. Basically, for an IP packet in transit,  the IP address is changed from one to another in a pre-determined manner.

Next question would be the need to translate (or map) one IP to another. There are multiple reasons for this translation as detailed below:

  • Translation of private addresses into unique public addresses when accessing the Internet: Many organizations use private address space internal to the organization with a view of conserving the IP addresses. When a host with a private address needs to access another host across the Internet, the private address has to be mapped to a public IP address before sending the packet over the Internet. The reverse process takes place when the packet arrives from the public Internet addressed to a host withing the organization.
  • Translation of addresses when transitioning internal addresses from one address range into another: Within an organization, some times need arises that an address range is mapped to another address range for compatibility reasons. For example, Company A acquires Company B, then the former may like to map the address range of the later for policy and compatibility reasons. NAT is used under such circumstances.
  • When simple TCP load sharing is required across many IP hosts: Assume that you have an application server catering to the needs of the entire organzation and you would like to distribute the load across various such servers for faster response times, but the end-user sees only one server (IP address or host). In such cases, NAT allows you to distribute the load across several servers and and yet the users communicating to a single host.

Now that we know some of the cases where network address translation is useful, we discuss various types of NAT:

  1. Static NAT: Maps an unregistered IP address to registered IP (globally unique) addresses on one-to-one basis.
    The command, ip nat inside source static <local ip> <global ip> configures address translation for static NAT.
  2. Dynamic NAT: Maps an unregistered IP address to a registered (globally unique) IP address from a group of registered (globally unique) IP addresses dynamically. It is not necessary that a host gets the same IP address for the second time.
    The command, ip nat inside source list <access-list-number> pool <name>
    is used to map the access-list to the IP NAT pool during the configuration of Dynamic NAT.
  3. Overloading NAT:A special case of dynamic NAT that maps multiple unregistered IP addresses to a single registered (globally unique) IP address by using different port numbers.
    Dynamic NAT with overloading is also known also as PAT (Port Address Translation).
  4. Overlapping NAT: When a host on your network is assigned an IP address that is on the same subnet as another device on the Internet or external network, the result is overlapping networks.  It is possible to allow communication between two overlapping networks without having to renumber any devices by using Network Address Translation (NAT).

Below are some of key terms related to NAT which play important role in IP address Translations:

  • Inside Local Address
  • Inside Global Address
  • Outside Local Address
  • Outside Global Address

In the above term, first we break down the words Inside, Outside, Local, and Global for clarity.

  • Inside = Under control of the customer. This will reside inside the customer network .
  • Outside = Customer can’t control and reside outside the customer network.
  • Local = Private addresses and refers to the address on the inside of your network.
  • Global = Public IP addresses which are Globally routable addresses. This refers to the address on the outside of customer network.

Now we come back to the 4 key terms of NAT:

  • Inside Local Address – Private addresses that customer can control. This is the IP address assigned to an end host on the inside  network. The IP address is provided by the customer himself and is not required to be taken from IP address authority or Service provider.
  • Inside Global Address – Public addresses that the customer can control. An example is the globally routable IP address(es) ISP provides to the organization (customer). A local address can’t traverse the Internet. Therefore, it needs to be translated to a global address before entering the global Internet. A packet with local IP address (generated on the local host) and destined for another host on the public Internet, needs to be translated to a routable public IP address given by the ISP.
  • Outside Local Address – Private Addresses that are outside of customer’s control. This is the address that the inside hosts use to refer an outside host. The outside local address may be the outside host’s actual address or another translated private address from a different private address block. In other words – The IP address of an outside host as it is known to the hosts on the inside network.
  • Outside Global Address – Public addresses that are outside of customer’s control.These are Globally Routable addresses and is the public IP address assigned to the end device on the other network to communicate over internet.  For example, if an internal host is accessing Google mail server on the Internet, the address of the Google mail server would be the Outside Global address and you have no control on the IP assignment on Google mail server.

By looking at the figure above, we can interpret various addresses as below with respect to host 10.1.12.1 and outside host 200.1.2.3

  • Inside Local address:10.1.12.1
  • Inside Global address:132.0.1.100
  • Outside Local address:192.168.1.7
  • Outside Global address:200.1.2.3

As you can see Inside Local and Inside Global corresponds to the customer and Outside Local and Outside Global corresponds to the outside host. Some times it would be confusing if this point is not clear during the exam.
