With the CCNA certification making waves in the technology world, it is important to keep track of which updates are coming and when. These updates are designed to help you advance your skills and keep up with industry trends.
CCNA Routing and Switching Updates
The CCNA routing and switching certification are valuable for those who want to work in networking. The CCNA certification is an entry-level certification that covers routing and switching basics. The CCNA certification is available through many vendors, including Cisco and Microsoft.
To be eligible for the CCNA certification, you must have at least a basic understanding of network fundamentals, such as IP addresses, subnets, and routers. During the CCNA certification exam, you will also learn how to configure switches and routers using command-line interfaces (CLI).
If you are interested in pursuing the CCNA routing and switching certification, make sure to check out these updated topics:
1. New features in Cisco IOS Software Release 16.4(4)T: ICMPv6 Neighbor Discovery (ND) and IPv6 static routing on CatOS
2. New features in Cisco IOS XR Software: support for SVM-based Layer 3 routing and the Nexus 9000 family
3. Updated exam topics for the Routing Fundamentals curriculum from Cisco Learning Network (CLN)
IIS Installation, Configuration, and Troubleshooting
If you’re reading this, then you probably know that IIS is a web server application that many organizations use. You may also know that IIS has been updated several times, most recently in March 2022. This blog post will discuss the most recent update, how to install it, and some of the new features it includes.
We’ll also be discussing some common configuration issues and how to troubleshoot them. So if you’re using IIS, or plan on doing so shortly, be sure to read on!
Dynamic Traceroute
Dynamic traceroute is a powerful tool administrator can use to troubleshoot network problems. When used correctly, it can help identify the path packets take as they travel through the network.
The CCNA updates you should know about include:
1. The CCNA updates you should know about include dynamic traceroute enhancements that make the tool more accurate and helpful in identifying network problems.
2. New dynamic traceroute features now allow administrators to track packet loss and latency, making diagnosing and solving performance issues easier.
3. The updated CCNA exams also include coverage of these new features, so you can be confident you’re prepared for the real-world challenges of networking. You can see CCNA exam questions here now and learn more about the type of questions you might face in the exam.
ARP Table Flooding Attack
ARP table flooding attacks are an attack in which an attacker floods the ARP table on a network device with illegitimate ARP replies to cause the device to become unavailable. The victim’s computer then tries to access the network using the incorrect IP address, which can cause the device to crash or cause other problems.
IP Spoofing Attack
If you’re like most network administrators, then you’re familiar with the concept of IP addresses. IP addresses are the unique identifiers for each computer on a network. Each router on the network knows how to route traffic to its intended destination based on the IP address of the recipient. However, what if someone wanted to send traffic to a recipient that wasn’t actually on the network? This is where IP spoofing comes in.
IP spoofing is a technique that can be used to fool a router into thinking that a particular IP address is located on the network. This can be done by using a bogus IP address assigned to your organization or spoofing an existing IP address. In either case, the goal is to trick the router into directing traffic to destinations that aren’t located on the network.
There are two main types of IP spoofing attacks: reflection and amplification. Reflection attacks occur when attackers send counterfeit packets back towards the source device, which then causes them to be reflected towards the attacker. Amplification attacks take advantage of how routers process data packets. When an attacker sends a smaller packet containing malicious content, it can sometimes be amplified and sent out over the entire network.
Conclusion
CCNA certification from Cisco proves you have the foundational knowledge needed to work with their networking products. Recently, they released some updates to their curriculum that include new topics such as network automation and SDN. If you want to make a career in networking or stay up-to-date on the latest trends, you must study for and pass the CCNA exam.
