What is CCDA? Cisco Certified Design Associate (CCDA) certification is about designing the Cisco network in most efficient way. CCDA course is for validating all fundaments related to network designing, its cover void Variety of route and switch design and covers LAN, WAN, broadband, campus, data-center and wireless network design.Cisco recommends before you attempt the […]
Network design is getting more complex with complexity of our network with different type of multimedia and data traffic, so it is necessity that we have a proper design methodology that support out plan. In this article we will see some network design methodology. Some of the design approaches are as follows: PPDIOO Cisco three […]
Wireless Local Area Network Design This article is related to the wireless LAN, there are some prerequisite concepts which should be familiar to you and need to understand for better wireless design. You should be aware with: Wireless LAN Standards WLAN Security Cisco Wireless Design When we start to explore our WLAN we have to […]
Cisco Unified Wireless network is methodology for designing the wireless network and it have the following components: Wireless Clients Access points Network management Network Unification Network Services Wireless Clients: Wireless Clients includes the laptops, PC, Mobiles Phone, PDAs and IP phones. These all end devices are the part of access network. Access points: AP provides the […]
Security in wireless network is a very essential and while designing a WLAN you have to focus and consider the following important aspects of security. 1EEE 802.11i/WPA2: In WLAN we have different security protocols for security. One of the famous protocol is WEP (Wired Equivalent Privacy) that emerge with 802.11b standard but it is faulty […]
The main standard for wireless LAN is the 802.11. WLAN applications include inside-building access, LAN extension, outside building-to building communications, public access, and small office/home office communications. Some of the famous standards that are used in wireless communication are: 802.11 Wireless Standard: 802.11 is for wireless local area network standard and the original 802.11 standard […]
Once your network is design and deployed, then it must be managed by the operations team. Network management tools are used to gather operating statistics and to manage devices. Statistics are gathered on WAN bandwidth utilization, router CPU and memory utilization, and interface counters. In a large network you need proper network management to control […]
As a CCDA candidate you need to have high level understanding of IPv6, specification and IPv6 design issues. Also must understand how an IPv6 address is represented and the different types of IPv6 addresses. Why we need IPv6? IPv6 is a mechanism that is really put together to overcome the limitation of IPv4 standard. The […]
As a CCDA candidate we must aware with the IPv4 to Ipv6 transitions, using these transition methods you can design your IPv6 network or you can run both IPv4 and IPv6 in your network. Following are the Models are used for IPv4 to IPv6 transition. Each model provides several advantages and is advantages, the dual-stack […]
IPv6 types of Addresses Following are the most common types of the IPv6 addresses: IPv6 Unicast IPv6 Anycast IPv6 Multicast The leading bits of an IPv6 address can define the IPv6 address type, following are the starting Hexadecimal/Prefix of common IPV6 types: Starting Bits IPv6 address type or allocation 0000::/8 Unspecified, loopback, IPv4-compatible 2000::/3 Global Unicast […]
IPv6 address is of 128 bits and represented in eight octets of 16 bits. IPv6 addresses are in hexadecimal form, so each digit is of four bits, IPv6 address’s consist of possible digits are 0 1 2 3 4 5 6 7 8 9 A B C D E F. Representation of all hexadecimal number/digits […]
Difference between IPv4 and IPv6: Following are the some key features of IPv4 and IPv6 address, with these features you can compare these two version of internet protocols. We have the extended address space in IPv6, IPv4 is of 32 bits and IPv6 is of 128 bits Ipv6 addresses are globally unique. Fixed header length: […]
Deigning network with implementing security: CCDA security management is about the Implementation of security with some design standpoint, as a CCDA candidate you should understand the reason of network security and some efficient approaches for implementing the network security. You also need to focus on confidentially, integrity and Authentication. You can design a good secure […]
Network security System Life Cycle: As a Design professional security is one important aspect of job and as a CCDA candidate you should know about the security policy that is a key aspect of an organization’s network design. To offer the level of security that you need to enhance the network confidentially, integrity and Authenticity, […]
