Hey everyone, I just started my journey. I'm excited to see where it goes and I'm hoping a learn a ton along the way!!! I probably won't try to take the certification test for a 9 months to a year. I work full time and have a family, so I am on a steady diet of waking up at 4am to get my studying in for the day. :)…
hi guy i am new to this site. this site is so helpful in self studying.. i used to study N+ long time ago... but i passed today with 713 (i know i am so lazy) my test was tougher than i expected... let me give y ou guys a little bit of feed back.. 1. OSI model -- very easy, starightforward... 2. port number-- easy..…
What is the difference between subnetting a network vs using different network ranges For eg i have 160 hosts and i want to divide into two sections I can either use 192.168.1.1 to 192.168.1.60 for the first and 192.168.2.1 to 192.168.2.60 for second segment Or i can use subnetting 192.168.1.1/25 to 192.168.1.60/25 for…
Hi all, question on a fixed length subnet masking. If we are given 110.5.5.0/12 and are asked to find the fixed length subnets that would exist if we had a requirement to carve out 7 subnets from that, what would the subnet ranges end up being? I realize that it's a little hinky and you probably wouldn't be given a…
I don't have any real-world experience with networking, but having taken a college course and I am currently taking an exam prep course online. I seem to be able to memorize the concepts and terms but struggle with applying what I've learned to IRL scenarios. My question is it possible to thoroughly understand the concepts…
Lets say you have an IP of 165.245.77.12 and a subnet of 255.255.240.0. After applying the Magic Number Method you find out you have a first host of 165.245.64.1 and a last host of 165.245.79.254. But if we have a question that gives you that same IP address and subnet and they want for example 4 networks with at least 50…
I did this test from two PCs at home that are connected to a typical SOHO router, so the router is doing Network Address Translation. I pinged successfully an IP address from the two computers: ping 8.8.8.8. My doubt is, if ICMP doesn’t use port numbers, as it is only layer 3, how can the router send the replies to my…
I just passed my net+ 7 mins ago with a score of 763. now I have to take either CYSA/CISSP/ or Security+....FYI, I have an associates in Infosec. so, sec+ probably will be kinda easy....I work in AmEx data center as a net support (layer 1 ....egh!) and kinda want to start a carrier as a CyberSEC analyst or…
I recently recertified my CCNA R/S and i figured I might as well see how difficult the network+ is in comparison to the CCNA. I was able to pass. I hadn't study for either certification just relied on work experience. CCNA for sure was a bit difficult, however the new CCNA is slightly harder than the network+.
Just for curiosity, are this IP addresses and IP ranges possible? 1) 1.0.0.0/8 I guess this probably exists as a class A internet address range? 2) 0.0.0.0/24 or 0.0.0.0/8 ....to be used in a private network Any answers much welcome
