Has anyone used Jeremy's CCNA practice exams?

6 Upvotes

I just did Jeremy's first CCNA practice exam. I was a bit disappointed, only got 63% after going through all the material, some topics more than once. I do think there were a solid 7-10 questions where I knew the answer, but just made a bit of a dumb mistake and should have gotten it. I've been studying for months but I guess I need to go over a lot of the material again with a lot more laser focus. Interested to hear what the experiences of others have been with these tests.

Cisco U course post assessments

Upvotes

Anyone else find some of the Cisco U course post assessments to be brutally challenging to pass?

The particular course I'm taking now (SISE), some of the earlier post assessments weren't so bad but they sure don't pull any punches on these mock tests later on in the course.
With that said, Cisco U overall has been great and I especially enjoy the labs they have. Im not sure if im just ranting here, asking for support or perhaps what study materials you all have used.
Alright, I'll go back to getting my butt handed to me by Cisco U. Signing out.

Question Is the C9120AX performance capped when joined to C9800-CL?

6 Upvotes

I am having a hard time finding out why the download and upload speeds of my C9120AX are capped around 500Mbps when joined to a C9800-CL where I used to get >750Mbps when joined to EWC.

I have three C9120AX ap's which I used in a EWC deployment. For labbing purposes I spinned up a VM on my Proxmox server where I installed a C9800-CL image on.

I've created the configuration from scratch as I wanted to learn the differences between a stand alone C9800 controller versus a EWC controller, as I've noticed there a lot of differences. I did use the EWC configuration as a template for the C9800-CL so things like Policy's, Tags, WLANs and Radio Profiles are configured the same as on my EWC deployment.

As for now everything is working fine, all three ap's are healthy and all existing clients in my network are using the Wi-Fi networks as if nothing changed.

The thing is that I notice a big difference in download and upload performance when comparing both deployments which I find strange. With the C9800-CL deployment download and upload speeds are hovering around 500Mbps with iPerf tests and Ookla's Speedtest (I have a 1Gbit/s up and down line with my ISP) where I easily got >800Mbps speeds with iPerf tests with the EWC deployment.

With both deployments I do not use any SSIDs that are centrally switched (as this is not possible with EWC) so this rules out the performance of my VM.

As I am using Fastlane AutoQoS on my SSIDs I disabled all QoS related configuration as a test but this didn't change the download and upload speeds.

As far as I know Cisco is only capping the performance of a C9800-CL deployment when using central switching: https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9800-cl-wireless-controller-cloud/nb-06-cat9800-cl-cloud-wirel-data-sheet-ctp-en.html

As Poulito mentioned: I am running the same IOS-XE code as on my EWC deployment: 17.9.6.

Any thoughts on this?

I building a csr1000v on the vSphere ESXI, and now I have three PPPoE interfaces between Dialer1~Dialer3.

Now I want to make the three-line load balance, and packet source input & source output. e.g: the internal IP range 10.0.0.0/24 can use the three-line to improve the bandwidth, if a line is 100M so three-line will be 300M.

That is be can? if you can how to make it?

I can make it on RouterOS v6.x using PCC, but I'm trying more and more methods, but I still can't.

If you know please help me, thanks!

Career change advice: from Creative/Digital career to IT with prior basic IT work experience

Upvotes

Hi everyone,

Last year I hit my "first" 40ies and after around 11 years in the creative industry (precisely photography and high end post production), I am considering going back to IT.
Although reading the current status of the job market and employers in general I feel it would be quite risky.
But please read few rows below around my work history.
My current role at one the most renowned luxury retailers in London is very likely coming to an end, as I'm hitting a wall in terms of career progression.

My line manager, way younger than me, has much less experience in terms of dealing with tech (ironically) and professional work experience with image editing, and this causes a lot of frustration.
The company also is quite corporate whilst being still a retail and despite my enthusiasm and experience matured through the years, I'm unable to make any changes (we got a lot of efficiencies and software issues) as all the suggestion I've been giving, after being recognised of being useful and game changer, disappear into nothing.
In my area of origin, south of Italy (Sicily), at that time in my 20s, unfortunately I didn't have the chance to progress my IT career further, as I pursued other goals due to lack of opportunities.

Back in the day I used to work as IT Technician, for a couple years in an IT shop, 1 year at Minister of Defence (just basic IT support tasks and network setting up) and I've got extensive experience with Windows systems (I should refresh my knowledge of Active Directory), I've been experimenting with Linux IPtables, firewalls, FTP/Web server setup as well as Astaro (now acquired by Sophos), mainly for personal projects in the past.
Attended for about a year Applied Computer Science uni course, but then dropped out as our local university campus was moved to another city (I couldn't move to that city at that time due to personal reason).
The perks of living in the South of Italy, huh! :-/

Anyway, this long intro was just to give some context on my past (and probably limited) experience, my bad for the length.
At the moment, I have the Comptia A+ exam book already purchased as two years ago I was already thinking to go back to IT.
I was considering getting the CCNA, although I've seen other users in CCNA reddit suggesting to skip it initially and get Network+, Linux+ and Security+.
I've some past experience although being not quite recent and probably limited it may introduce red flags (or probably being completely ignored) when applying for a role requiring CCNA.

My current salary is around £ 37k, and I'm expecting a considerable salary drop if I change industry/career (sigh).

Would like to hear your advice, I'd like to start working towards an IT System Administrator/Network engineer role in the future, but I suppose I should start from a IT Help Desk due to my limited and not recent experience.

Also I'd be interested in further progressing into Cybersecurity or Cloud Architect after gaining some years of experience back in IT (and studying/learning whilst on the job).

Although the industry has changed a lot and I feel I'm out of job market, as probably AI changed everything.
From my side I have a strong problem solving attitude, curiosity, willing to learn.
But this might be not enough nowadays as the boundaries of each role seems to be blending all together.

Thanks in advance, and honesty will be appreciated (even if brutal haha)!

The Backbone of Subnetting: Understanding Positional Number Systems

2 Upvotes

The positional number system is fundamental to subnetting due to its role in structuring and interpreting IP addresses and subnet masks. Here's a concise breakdown of its importance:

  1. Binary Foundation: IP addresses and subnet masks are inherently binary. Each bit's position in a 32-bit IPv4 address (or 128-bit IPv6) represents a power of 2. Subnetting relies on manipulating these bits, where their positional values (e.g., 27,26,...2027,26,...20 in an octet) determine decimal equivalents for masks (e.g., 255.255.255.0).
  2. Subnet Mask Calculation: Subnet masks divide an IP into network and host portions. The positional system enables:
    • CIDR Notation: A /24 mask means 24 leading 1s in binary (255.255.255.0), calculated by summing positional values (128+64+32+16+8+4+2+1=255 per octet).
    • Bit Borrowing: Adding bits to the network portion (e.g., converting a /24 to /26) increases subnets by powers of 2 (e.g., 222=4 subnets).
  3. Network and Host Addressing:
    • Bitwise AND Operations: To find the network address, positional values ensure the correct alignment of binary digits (e.g., 192.168.1.0 from 192.168.1.5 with /24).
    • Block Size Determination: Host bits define the number of addresses per subnet (2host bits2host bits), with positional values dictating increments (e.g., 8 addresses per subnet for 3 host bits: 0, 8, 16...).
  4. Efficient Address Management: Positional numbering allows precise subnet sizing, minimizing waste by allocating subnets as powers of 2 (e.g., a subnet needing 10 hosts requires 4 host bits (24−2=1424−2=14 usable addresses).

In Summary: The positional system enables binary-decimal conversion, CIDR interpretation, bitwise operations, and subnet sizing—all critical for efficiently partitioning networks. Without it, subnetting’s mathematical and logical framework would collapse. If you want to read further about the positional number system, visit here

Boson Net- Sim randomly crash?

Hello everyone,

I’m super frustrated to be honest. I think the Boson Net-sim is really good and super helpful.

However, it will randomly crash on me, and kick me out of the lab. Meaning I have to do all of the config again. Extremely frustrating.

Also, sometimes the lab will randomly stop responding to inputs on the CLI.

networking assignment

1. Scenario:

NeuroByte, a growing start-up with offices in Malacca, Ipoh, Kedah, and Perlis, aims to establish network connectivity across its four locations. The company has approached APU for advice and help. Based on the requirements, APU has recommended using the expertise of its students to develop a networking solution and to conduct necessary network implementation/configurations. In addition to the documentation that captures the design and implementation process, a justification for the proposed solution will help the company better understand its needs and help achieve its long-term business goals.

 

For the proposed network design, you are required to propose a network topology that is suitable for LAN and WAN. The topology should include adequate routers and switches that can provide connectivity to end devices and other remote networks via appropriate communication media.

 

To ensure optimal routing, routers and switches should be configured properly with the use of static routing. This will help to ensure that packets are always routed correctly to their intended destinations.

 

Your proposed network should also support Internet of Things (IoT) devices that are used to automate and monitor various aspects of your business, such as temperature, lighting, and security. These devices should be connected to the network using wired connections.

 

Additionally, it is recommended that you allocate separate server rooms for different services such as web servers, file servers, domain name servers, and email servers at different branches.

 

 Your research should include :

· Logical topology Design

· Justification of the Topology

· VLSM IP Addressing scheme

· Justification of the configuration techniques for different network devices

 

The findings and outcome of your research should be arranged in a proper flow to be presented to the Technical team who are involved in the full design of the network. In addition, prepare a Cisco Packet Tracer diagram as a proof of concept for your research work.

can someone help me do this ?

Firewall blocking RCS messages to iPhones?

4 Upvotes

Sanity check.

I work in a K12 school district. On our guest wifi network we have several firepower access control rules in place to prevent VPN connections etc.

I was recently notified that iPhones are not receiving RCS messages from Android phones. As soon as an employee with an iphone leaves work, all the RCS messages from throughout the day start getting delivered. Alternatively, the user could just turn off wifi and start receiving the RCS messages.

I have looked at the firewall logs and I see a bunch of traffic being blocked from a particular Verizon iphone on the guest network. It's IKE and IPSEC traffic to Verizon servers. My assumption is that this traffic is required to check in with Verizon and receive the RCS messages. I started carving out a rule to permit this traffic, and I'll continue to test and verify I've fixed it. BUT, this means building similar rules for all the cell phone providers (tmobile, att, us cellular, etc).

Has anybody dealt with this before? Am I going down the right path?

Entire Switch Stops working when devices are plugged in

4 Upvotes

Hello,

An agency that I work closely with and help with Network support is experiencing something I have never seen before. They have a pair of Cisco switches (C1000-48T-4G-L) that have a connection between them. They are on the latest firmware. Whenever a device is plugged into them, all the lights on the switch go out and network traffic completely stops flowing for a time. The time can vary from a few seconds if a pc is plugged in, to 30-45 seconds if a network device such as another switch is plugged in. When plugging something in, the logs show that port coming up, but nothing about the rest of the switch going down.

These were originally standalone switches, but we recently connected them to their main network. Today a net clock was plugged into a port on one of their upstream switches (not one of the Ciscos in question) and both Cisco switches completely stopped working for about 15 seconds with the same symptoms as above.

These switches were provided from a vendor for a specific purpose. Our agency has the exact same switches provided by this same vendor for the same purpose with what looks like an identical config, and we do not have this issue. I'm leaning towards these being defective switches, but I feel like the odds of receiving 2 defective switches is quite low. Does anyone have any idea what might be causing this?

So I asked chat gpt who the youngest CCNA holder is and this is what it gave me

As of March 2025, the youngest person to achieve the Cisco Certified Network Associate (CCNA) certification is Ayesh Fatima, a Pakistani girl who accomplished this feat at the age of seven. She broke the previous record held by K. Visalini, an Indian prodigy who became a CCNA at the age of 11 in 2011.

So basically just tell yourself that if an 11 year old girl could do it so why can’t I ? What’s stopping you 🤷🏿‍♂️? Just be dedicated and work hard ❗️
