      Cisco Software-Defined Access (SDA) primarily leverages Intermediate System to Intermediate System (IS-IS) as the underlying routing protocol for its control plane. While Enhanced Interior Gateway Routing Protocol (EIGRP) is supported in the broader Cisco DNA architecture, it is not the default or recommended protocol for the SDA fabric control plane. EIGRP can be used in traditional network segments that connect to the SDA fabric, but the SDA fabric itself will rely on IS-IS for internal routing. Hope this helps!

    This might be a dumb question but is it possible to have traffic route automatically to different address if that certain address is down.

    • @NajQazi
      @NajQazi Před 23 dny

      Great question! The simple answer is yes, you can use object tracking to achieve this. Object tracking allows you to monitor and track various objects. If you have an active/passive architecture, you can track the next hop of the primary route, which would be the IP address of your service provider's PE device. In the event that it goes down, object tracking can automatically facilitate failover. Hope this helps!

    That was an awesome and clear explanation of what ACLs and ACEs are, but it would have been nice to see some examples of the function of real ACLs, like DENY ICMP or some other traffic manipulation... There seems to be so many logic bombs with ACLs, you can find yourself locked out of your own switch if you aren't careful...

    • @NajQazi
      @NajQazi Před měsícem

      FTP is not typically used for collecting and storing syslog messages. Instead, a dedicated syslog service is required. Common services for this purpose include: - Syslog-NG - rsyslog - Kiwi Syslog Server - Splunk - Graylog These services specifically handle the reception, storage, and management of syslog messages over the network using the syslog protocol (typically UDP port 514 or TCP port 514).

    How does authoritative dns server knows who was the original requestor?

    • @NajQazi
      @NajQazi Před měsícem

      The authoritative DNS server doesn't know the identity of the original requestor. Here's why: The recursive resolver is the middleman: When you type a domain name into your browser, your request typically first goes to a recursive DNS resolver (often provided by your ISP or a third-party service like Google DNS). This resolver acts as an intermediary, performing the various steps to find the IP address associated with the domain. Queries are stateless: Each query sent to an authoritative DNS server is independent and doesn't carry information about the previous queries in the chain. The authoritative server simply responds to the query with the requested DNS records (e.g., the IP address). It doesn't maintain any information about who initiated the original request. Privacy considerations: Revealing the original requestor's IP address to authoritative DNS servers could have privacy implications. This is one of the reasons why DNS resolvers act as intermediaries, shielding the original requester's identity. Exception: There's a potential exception if your resolver is configured to use DNS over HTTPS (DoH) or DNS over TLS (DoT). In these encrypted protocols, the resolver's IP address is visible to the authoritative server. However, even in this case, the authoritative server still wouldn't know the identity of the original device or user who initiated the request on your local network. Hope this helps!

      @NajQazi Před 2 měsíci

      Well, yes and no. Most students start learning about networking and CCNA concepts with zero background or experience in IT. But as they continue to learn and apply their understanding by doing hands-on labs. That's when the magic happens. The hands-on part makes the knowledge stick. For someone looking to change their career to IT or who has never worked in IT, I don't want them to get the idea that without experience, they can't understand the material. For most people, the typical path to a career in IT is to get a college degree or IT certifications. With that foundation, they can apply for jobs and have a pretty good chance of getting hired. Hope this helps!
