“Ağ mühendisliği yolculuğuma başlarken CCNA benim için büyük bir dönüm noktasıydı. Konular karmaşık görünüyordu, neye nasıl çalışmam gerektiğini bilmiyordum. Ancak doğru kaynaklar ve istikrarlı çalışmayla bu süreci başarıyla geçtim. Şimdi edindiğim deneyimi sizinle paylaşmak istiyorum.”

CCNA Nedir?

Cisco’nun 200-301 CCNA sınavı, ağ yönetimi, IP adresleme, güvenlik, otomasyon gibi temel konuları kapsayan, ağ mühendisliğinde bir temel taşıdır.

CCNA Sınav Konuları ve Ağırlıkları:

Network Fundamentals (%20)

Network Access – VLAN, Trunk, STP (%20)

IP Connectivity – Routing, OSPF, Static Routes (%25)

IP Services – DHCP, DNS, NAT (%10)

Security Fundamentals – ACL, Port Security (%15)

Automation & Programmability (%10)

Hazırlık Stratejileri:

Güvenilir Kaynaklar:

Kitap: Wendell Odom – CCNA Official Cert Guide

Online Eğitim: Orhan Ergun CCNA Eğitimi ← 🔗 (Backlink buraya yerleştirildi)

Simülasyonlar: Cisco Packet Tracer, GNS3, EVE-NG

Katmanlı Öğrenme: OSI modelini temel alarak konuları sırasıyla öğrenin. Önce subnetting, ardından VLAN, sonra routing vb.

Günlük Plan: 30 gün boyunca günde en az 3 saatlik çalışma programı oluşturun. Her 3 günde bir konuları tekrar edin ve simülasyonlar yapın.

Son Gün Hazırlıkları:

500+ pratik soru çözmüş olun.

Cisco’nun deneme sınavlarına girin.

Gerçek sınav ortamı simülasyonu yapın.

CCNA'nın Size Katkısı:

Bu sınavdan sonra iş görüşmelerinde daha çok çağrıldım, hatta birkaç iş teklifini karşılaştırma şansım bile oldu.

Siz de aynı şekilde kariyerinize güçlü bir başlangıç yapmak istiyorsanız, kendi yol haritanızı oluşturmanız şart.

How to Use a Network Mask Cheatsheet to Speed Up Subnetting in 2025 We will explore the in-depth process of enhancing subnetting using network mask cheat sheets.

I completely forgot I skipped over the 1.4 subnetting lesson cause I had just learned it but it's totally gonna screw up my note taking process with these practice tests if I don't go back and do it anyway. '

Damn it XD and here I thought I could get away with not relearning subnetting for like the fourth time. But hey, gotta sneak IPv6 addressing and hexadecimals in there somewhere I guess. :P

Subnetting divides a large network (high bits) into smaller, manageable segments (lower bits) using a subnet mask. This creates more efficient IP address allocation, improves security by isolating broadcast domains, and allows for better control over network traffic.

I’m just imagining a SongV family would be their kid asking about netrunning to So Mi and she nearly spits out her drink. That or V and So Mi at their kid’s school in the principals office because their kid hacked something.

While I'm not sure if they'd consider having a child due to their hectic lives. If they ever do, yeah, they'd probably get called to the principal's office often 😆

Had to do the second to last one to set the IP address and network info on a printer at work once 🙃

It didn't even let me click down at zero to rollover backward and go down from the max 🙃🙃🙃

Oh yeah! Reblogging to add my friend's tags:

#if you set your computer to a metered connection it can't update without your consent (:

This works on Windows 10, not sure about 11 yet though. (It's in the Settings menu, network settings, and I think you have to go into the settings for the specific network you're connected to. If you do a network reset, it removes that setting, so be sure to set it back afterwards!)

Also I believe no piece of software except for internet browsers should have always online internet connection. In fact, if you have something like an multiplayer game, you should go and click a very visible, very noticeable button that allows it to connect to the internet. If there is an update to an application, even your own OS, it should be in a very, very visible notification and only start with your express consent. You should be able to tell when something in your computer is connected to the internet. If you update your program in the background you should be shot.
