hello good people
I have this question that comes on my mind is about that i connected my DVR to the router that is connected to the ISP, because I want to monitor the place remotely via the app on my phone.
I know my whole traffic is transferred to the ISP site, so I am wondering if he can act like the man in the middle and sniff my videos?
I am using a Dahua DVR, and the app is DMSS

I am new to Raspberry Pi. I want to buy one to install an OS, connect a small screen to it, and use it for regular programs, but when I search on Amazon, I find different prices between the Raspberry Pi 3 1 GB RAM and the Raspberry Pi 4 2 GB RAM
My question is regarding what I will use the Raspberry Pi with; which version should I choose?

The company that I am working for has the server room right next to me
Every single day, there is no fan noise coming out of the server, but today is different
That noise of the fan is very loud, and I am wondering what could cause this rack to git it to go like this?
Is it that temperature or something else?
hello good people
I am a computer science engineer who graduated in 2025.
I also got certifications in wireless and fiber DWDM networks from an online course
I worked as a GPS device installation tech for fleet tracking for 1.5 years before I entered the university.
My question is
Can I apply to Data Center Tech because I am in the middle of CCNA learning?
Because I don't want to apply to companies without this certificate or the low networking experience that I have,
I applied before for one of the AWS internships, but I got rejected.
So I stopped applying because I heard from a networking guy that if you applied to companies without experience or a CCNA certificate, this would make your CV and your name saved in their Database, and the chance of being accepted in the future is short.
Any help, please?

Hello good people
I am a new CCNA, and now I am in the VLAN section, and a question has stopped me.
Let's say we have one switch divided into two VLANs. The first VLAN has the IP 10.0.0.1/24, and the second VLAN has the IP 10.0.0.2/24, and we connected a router to this switch
. The question is, can the IP in VLAN 1 reach the IP in the second VLAN?
The person who explains this topic in the video said no
Because the packet will not come out of the sender device ( PC )
If it is correct, then why?
Could you please explain this to me
thank you

I have recently graduated from university with a B.S. in computer engineering, and I am starting to search for a job on LinkedIn
I saw one of the job advertisements for a data center technician internship at AWS, and I want to apply for it, but I am a little bit hesitant about what type of form I should use to make sure everything is professional.
I asked some of my friends about the form they told me you should use the Harvard resume form.
Is that correct, or do you have another opinion?
I am grateful for any kind of help
Please, I need a quick tip because the advertisement was published two weeks ago.

hello good people
I am totally new to CCNA, and now I am in the middle of the OSPF section. I am facing a network that i need to connect a bunch of routers together and connect them with an edge router. I then connected the edge router to the ISP router using this CLI command: R3(config)# ip route 0.0.0.0 0.0.0.0 16.0.0.0. Then I activated and advertised the ISP path using the R3 by adding this command R3(config)# router ospf 1 then R3(config-router)# default-information originate
a simple diagram to explain my network
R1------R2-------R3---------ISP------server ( with a bunch of PCs connected to each router )
Now, after I advertised the ISP route, I tried to reach it from the R1 to the ISP, it s working fine, but if I want to reach the server from R1 or R2, the packet fails
I just cannot reach the server via the R3(edge router )
I wrote it down to ChatGPT, and the solution was to activate the OSPF on the ISP router.
My question is

My question is
Is it correct to activate the OSPF on the ISP router, or should the OSPF work on the edge router
Do you have any other solution other than activating the OSPF on the ISP?

hello good people
I am new to CCNA, and I am in the middle of learning OSPF now. I want to reach the pc with the IP 17.0.0.2 from any router on the network by activating the default route on the edge router ( R3), then I make it teach the wrist of the networks the default route 0.0.0.0 0.0.0.0 16.0.0.1 using this command ( ISP_R(config-router)# default-information originate )
If I am pinging from R13 to 17.0.0.2, everything goes well, and the packet reaches its destination.
But the problem is that if I am pinging from R1 and R2 using the default route, the packet doesn't make it.
I used the command ( traceroute) to figure out what the problem was. It shows that it has stopped in 13.0.0.2, which belongs to the R3.
Also, I made sure that the default route is discovered by the other routers using this command ( R2# sh ip route ).
I will attach a screenshot of the network and the CLI commands with the output.
Any help, please?
Hello good people
I am new to networking and CCNA, but I want an explanation of what happened in my manager's office.
Two days ago, I just entered the office and sat as usual on a day, but the strangest thing was the ringing sound of the IP phone at the manager's desk in the morning, usually at 8 am, the phone was not ringing, we thought the manager's wife was trying to reach him because the IP phone did not stop ringing.
After one hour of unstoppable ringing, one of the employees took a deep breath and entered the manager's office to find a way to turn down the ringing sound, but he saw on the phone screen a number of the IP phone in the same company, but we know that there is now one in the other office trying to contact the manager.
My question is, is it possible that something wrong happens to the network, which makes the IP phone ring by itself to another IP phone?
