Packet tracer ejercicios

Hello all,
To start, please bear with me, I am extremely new to both Cisco and IOS, with my only experience being my networking class where I had to use a software called NetChallenge, and a tiny bit of PacketTracer.
I am currently experimenting with reverse SSH at work on a 2801. We are planning on using NICs on a 2900 Series box to act as a terminal server, and I am currently going through the process of testing the feature. I got reverse telnet working, but I am struggling with doing it over SSH. I don't believe this will be used in production, it's more of a practice/research thing for me.
I have the SSH server configured properly on the 2801, and I think it's working? I followed the official PDFs listed here and here.
Am i missing something here?

Pessoal, minha situação é a seguinte: atualmente estou no segundo semestre de ADS na Universidade Católica de Santos (EAD). Tenho me esforçado muito e feito muitos cursos complementares. Já fiz os seguintes cursos:

• Python 1, 2 e 3 - Curso em Vídeo
• Git e GitHub - Curso em Vídeo
• Modelo OSI – HBR Cursos
• Cisco Packet Tracer - HBR Cursos
• Banco de dados relacional e não relacional – Udemy (Geek University)
• Java – Udemy (Nélio Alves)
• Estruturas de dados (Dr. Jones Granatyr)

Meu problema é o seguinte: vou me casar em julho e precisarei mudar em função do meu atual trabalho. Como preciso comparecer ao polo para realizar provas bimestralmente, não sei se poderei continuar na mesma instituição. Caso tenha que mudar, tenho algumas considerações que gostaria de compartilhar para ouvir opiniões. Acho o conteúdo da faculdade muito superficial, não sei se é porque sou de outra época (me formei no ensino médio há 17 anos), mas agora parece que não aprofundam em nada. A maioria das matérias, eu aprendo assistindo aulas da Univesp, USP e na UFABC. Vocês acham que, se eu trocar de ADS para ciência da computação, terei um aprofundamento maior nas matérias?
Outra coisa, vale a pena fazer ciência da computação EAD, tendo em vista que a pessoa não utilizará os laboratórios? Vocês sabem como fica a questão da iniciação científica?
No meu caso, vocês aconselham a trocar ou a terminar o ADS e fazer ciência da computação como uma pós?
Para finalizar, infelizmente trabalho e não disponho de tempo para cursar uma universidade pública. Dentro da opção das particulares, vocês indicam alguma? Tenho visto muito o nome da Uninter e Unicesumar. Vocês as recomendam?

I'm trying to do CCNAv7 Skills Assessment - ENSA. It has 2 routers, 2 switches, PC-A and PC-B. I'm sure you can find it on what site "you know what"
But every time I put it in, on ANY router in packet tracer, it says "Server reset connection" So I go to put in the command :
ip http secure-server - it doesnt recognise it. I've tried this with many routers but no avail. Same problem.

hey all. Doing this assignment right now : https://itexamanswers.net/hands-on-skills-exam-ccnav7-ensa-skills-assessment-answers.html#section-instructions
I've actually already done 90% of it twice myself but I'm stuck. everytime I start to test by using the http in the web browser, it doesnt work, "Server reset connection," so I say okay I'll put in the command it recommends aaaaand it doesnt recognise it, on ANY router.
I don't know what to do.

how can i know where the issue in the negotiation is in packet tracer?

Hello,
I hope this is one of them things that I laugh about but I feel like I'm going a bit mad.
I am trying to play around with PT and I have a server with 2 NIC's and 2 DHCP Pools - 172.16.10.0 and 172.16.20.0 on each NIC.
Each NIC is statically assigned an IP of Gig0 172.16.10.5 and Gig1 172.16.20.5
I have connections from the server to 2 different switches - SW1 Eth1/0/3 - Access VLAN 10 and SW2 Eth1/0/3 Access VLAN 20
Each switch is connected by L3 PortChannels and they each have an SVI for their respective VLAN (SW1 172.16.10.1 - SW2 172.16.20.1) - The routed ports are 10.0.0.1/30 on SW1 and 10.0.0.2/30 on SW2.
I then have a static route between them which works because I can ping the SVI of the opposing switch
I can ping 10.5 (The server) from SW1 and 20.5 from SW2 as well.
However, I can't ping 20.5 from SW1 and I can't ping 10.5 from SW2 - Despite having a route for it.
When I use the real time function to investigate, I notice that the server has a default-gateway of 172.16.20.1 - Which is weird because I set the DFGW for each NIC, It doesn't allow me, AFAIK, to have a global DFGW for everything.
So naturally, when the ICMP is generated and sent from SW2 to the server - The correct initial process happens; a L3 PDU is sent from SW2 towards SW1 over Po1 - SW1 receives it, notices the MAC is for itself and deencapsulates the frame and see's that it is a L3PDU and performs a look up into its route table for 172.16.10.5 - See's an entry and sends a frame out of the relevant interface (Eth1/0/3)
The frame is then seen by the server on NIC0 and acknowledges that it was for it and opens the L2PDU and sees that it is an ICMP request - The server then says "I have no route for 10.0.0.2 send it to my default gateway of 172.16.20.1 with this destination MAC" back to SW1 - And this is where the issue is, because the destination MAC for that default gateway is not known on SW1 (Because it is for the SVI on SW2) SW1 sees it as unknown unicast and forwards the frame out of every port except 1/0/3 where it was received - Since these are L2PDU's, the frames are not sent over the Po1 and thus the frames are dropped.
I feel like my setup is incredibly basic and I have checked the config dozens of times and stepped through each step of the packet's journey, yet the behavior that seems at odds is with the server.

How many questions did you have? How many simulations did you have?
Should I be doing packet tracer challenges? If so, where can I find those packet tracer challenges? Someone suggested test dumps but I know CompTIA said they’re illegal but does Cisco, and is it BIG illegal or “don’t get caught” illegal?
This is a job requirement for me and I’ve been studying for 6 months, but learned I spent 4 months on a wildly outdated FedVTE course. I’m also the household breadwinner so getting sacked over this is not an option for me.
Basically I have test anxiety and I. Am. Panicking.
Help?

I am putting together a packet tracer sim for a competition. A firewall isn't required, but could probably score some extra points.

Hey everyone,
I'm about 8 months into my first IT job (Help Desk at a small MSP). I have my A+ and have recently started studying for the CCNA. I'm curious what used lab equipment I can purchase relatively cheaply and still be relevant to help me study and understand concepts. Ideally a L3 switch to practice on.
I know I can use Packet Tracer, but I'm very hands on and like to have the hardware to experiment with as well. And yes, I tried searching first but the threads are a bit old.
Thanks!!

Cisco subnetting packet tracer
Hello I am new to networks I have been given a task of setting up a network with pcA connected to router, connected to switch connected to pcB.The ip address is 192.168.25.0/24 but I have subnetted the mask so it’s /27 now and subnet 1 is 0-31 and S2 is 32-63 pcA is 192.168.25.1 R1 g0l0 192.168.25.30
Subnet 2 PcB will be 192.168.25.33 R1 192.168.25.62 Switch 192.168.25.61
But I’m not sure what the default gateway will be for both subnets and also the vlan1 is that the same IP as the switch I’m setting this up on packet tracer.

Got an interview set up this Friday for a job. Pay rate is 80k-100k for a senior it support role. I’m looking forward to it. Surprisingly the technical assessment was not hard and most of everything I knew and studied for on my network+ cert and years of experience with Azure.
Here is the job description for requirements:
6+ years of recent end-user technical support experience, with a focus on executive-level users. Extensive expertise in macOS and Windows Desktop environments. Proficiency in Microsoft technologies: Windows Server, Active Directory, Exchange, and Office 365. Experience in implementing and supporting networks, including switches, firewalls, and TCP/IP, DHCP, and DNS. Familiarity with cybersecurity tools and best practices, encompassing next-generation antivirus, endpoint protection, DLP solutions, disk encryption, SSO, and MFA. Strong problem-solving abilities and attention to detail. Excellent written and verbal communication skills. Effective time management and prioritization capabilities. Capacity to thrive in a fast-paced setting and perform under pressure. Availability for daily on-site presence (Monday-Friday). On-call availability once per quarter for a week. Education: High school diploma.
Now 1. I have 6 years exact of Tech support experience. I have extensive experience in windows and some in Mac. But with Google I’m sure I can figure out Mac stuff.
Now 2. I have proficiencies in everything besides windows server. I took a course on it and played around with it on my home lab but nothing too serious at best I know where to find things and can do MX/cname records and that’s it.
Now 3. I have a network+ cert and I’m in progress of my CCNA so I understand these terms and how they work and what they do. But so far I have only played around with firewall rules once, I have only played with switches once at my job, and I did troubleshoot a lot of vpn issues.
Now 4. I have strong problem solving skills, written, verbal you name it and I’m fantastic at customer support I have 7 years of experience in that so no issue there.
Now 5. I’m just concerned I’ll have to do some hands on Cisco stuff they asked for experience with Cisco meraki. I have only used Cisco packet tracer lol. I know what VLans are and topology yadda yadda I’m just worried about getting on the job and I get a hard ticket where they like we need certificates set up for a new site, or they need help troubleshooting a switch or whatever happens and then I don’t know and I’m just there googling. They said there will be training and push towards certificates too which is nice.
Maybe I’m having imposter syndrome it’s small company 11-50 people so I will def be sticking out like a thumb if I fuck up.
Should I be learning anything as I prepare for interviews I really want the job I feel confident in the things I do know and my ability to analytical but am I tripping or will I be okay? What if they ask me harder questions in the interview?

Hey All - I suspect it’s just a packet tracer kink but thought I’d ask if anyone has run into the same problem. I’m working through a lab in Neil Anderson’s course and ran into a small issue. I have a floating static route configured as a backup route to EIGRP. However, when I shut down the link on the router that was advertising the EIGRP routes, the static route that was in the routing table previously as the backup route disappeared completely. So, instead of only the EIGRP routes disappearing, the static route disappeared from the routing table as well when it should have taken over.

Hey everyone!
I've lurked here and occasionally participated for some time now and some of the more common questions i've seen are "what should I simulate?" and "am I ready to take the exam?". Both of these questions were big for me before I got into networking professionally. I studied and did labs that I could find but I had no idea what was considered a real-world situation. Even more so, I didn't get any experience with an organically-growing network; it was either handed to me in an almost-completed state or it was something just basic and didn't really get anywhere.
Would there be interest in a series of packet tracer lab scenarios that have actual real-world value? It would be setup how I would expect to see it if the project were given to me to complete. Here is the first lab scenario I came up with:
Scenario 1
You are the owner of Granite LLC, a brand-new startup specializing in all things Granite. Your headquarters is located in Kansas City, KS.
You are a company of one in a small office. You have big plans for the company but you have to start small, and your network is no exception.
Luckily for you, you were a network engineer previously so you don't have to subcontract the management of the network to anyone.
Let's start small. You have been given a 24-port 2960 switch, a desktop and a server. Complete the following objectives:

1. Create a basic, flat network consisting of a single VLAN, called "USER". Use VLAN 10.
   
2. Connect the desktop and server to the switch. Port 1 and Port 20, respectively.
   
3. Assign the USER VLAN to both devices
   
4. Assign the IP address 10.1.1.10/24 to the desktop and 10.1.1.5/24 to the server.
   
5. Label the interface descriptions appropriately for both device interfaces on the switch.
   
6. Set the hostname of the switch to "GRNT-KCK-SW1"
   

Proof:
Both devices should be able to ping each other.
You should know which device is connect to which port when you issue command "show interface status"
Something along those lines. Each scenario would incorporate one or more exam topics. Each scenario will start with the result of the previous scenario and build up. So far I have come up with 10 scenarios and that doesn't even include any routing protocol configuration, so there is definitely room for more. This is simple enough that I don't think even a packet tracer lab file is required, but I could provide that if needed and you're comfortable downloading.
Thoughts? Suggestions?

I am wondering if in cisco packet tracer you can do performance testing?
I have this network where an office connects to a cloud , kinda haha but yeah so the goal is to test for Performance:

• Measure response times for accessing cloud-based applications to ensure optimal user experience.
• Evaluate system performance under varying workloads to identify potential bottlenecks or performance issues

Scalability:

• Assess the system's ability to handle increased user load by simulating high user traffic scenarios.
• Test scalability by adding simulated users and resources to determine the system's capacity to scale efficiently.

If cisco packet tracer does not provide the performance testing is there any alternatives or somehow get like some random performance testing even if its fake? as it is for a school project.

Just finished my exam minutes ago, and the result lists “PENDING””
The score in each section is 60/90/92/60/PENDING/70
I successfully did 2 labs yet only complete half in one.
What do y’all think?
Edit: I PASSED LETS GOOOO Got my final score report in 1 AM and checked it this morning, the ability in each percentages is 60/90/92/60/87/70, lol didn’t expect such a high score in security fundamental.
I used mainly Jeremy’s IT Lab and his packet tracer files, also the official cert guides by cisco press. Not a lot of things, but keep review them during my spare time.
If your currently a student like me, catch all the time you have apart from school to study for it, and make sure you use official exam topic to do the final review and ensure you are familiar with all the topics.
Hope all of you still studying can pass!

Hi All,
Aside from using packet tracer, GNS3, eve-ng and the sorts, I have a bunch of hardware listed below that I want to put together and setup a comprehensive lab to play around with and covering as many topics under CCNA and CCNP. Looking for tips on which devices to keep and omit and best use topology makeup. Keeping an eye out on some ISR 4000's to replace some of the listed hardware also, and any tips on devices to look out for. Note: I do understand you can go virtual but happy to do the hardware thing concurrently with PT and I already have the hardware stacked up on my desk.
I've been out of networking engineering for over 10 years now and hoping to get through CCNA in reasonably quick time and then progress through CCNP as time permits. Never certified and been procrastinating to do something but changing IT career track and certifications is now more of a requirement.
Thanks for your help and opinions in advance.

Not sure if this belongs here, I’m pretty green to all of this so if I embarrass myself feel free to let me know just curious me a bit of slack lol
I’d really like to setup my own NAS but I have no idea what brands are good or where to begin. Does anyone have any advice?
I do aerial photography/videography, 3D modeling and mapping, I do a lot of rendering with it in the construction industry (I have a website and insta I post some work too if anyone is interested in seeing bridges blow up ) but I need more storage and I’d really like to localize a cloud type setup.
My questions are, what brands are a good go to? I’d be willing to spend a decent amount of money for the right setup. Ideally id like 20-30TB and I’d really like it to have some kind of pcie expansion. Also maybe an NVMe or ssd slot as well.
If anyone can point me in the right direction or give me some tips or pointers you know I could use just getting into this , I would greatly appreciate it. I do build my own PC’s, I’ve spent a year or two messing around in packet tracer, and I’m pretty familiar with configuring firewalls so I’m not completely green but I don’t feel confident enough to really admit to having any knowledge on the subject.
Any help would be greatly appreciated .
Thank you!

Hello everyone, I have configured a little network for my college assignment that is a proposed network for a company trying to go global and need 5 networks to be connected to each other. Everything works great in it but I have two issues with it, vlan20 which contains network 2 is unreachable by any other vlan and the bigger issue, I have some basic configurations on two routers to act as ISPs and they are unreachable. I configured them to showcase my NAT tables but pings from or to them just fail. Can someone please point me to where any of my mistakes have been made? NS_Assignment 1.pkt
