Which VLAN identifier does a Cisco switch assign to access ports when no explicit VLAN membership configuration has been applied?
| 2 | Traditional Three-Tier Network Architecture β bu enterprise tarmoqlarda ishlatiladigan klassik 3 qavatli arxitektura.
1. Access Layer
Qurilmalar tarmoqqa shu qatlam orqali ulanadi:
PC
Laptop
IP Phone
Access Point
π Vazifasi: endpointlarni ulash.
2. Distribution Layer
Access va Core orasidagi boshqaruv qatlami.
π Asosiy vazifalari:
Routing
Inter-VLAN communication
ACL / Filtering
Security policies
Traffic control
3. Core Layer
Tarmoqning eng tezkor backbone qismi.
π Asosiy vazifasi:
Katta hajmdagi trafikni juda tez uzatish
Distribution layerlar orasida connectivity taβminlash

| 5 |  π CCNA Test Savoli
β Savol:
Routing jadvalida (Routing Table) tanlash jarayonida Administrative Distance (AD) nimani anglatadi?
β
To'g'ri javob:
Routing ma'lumotining manbasi qanchalik ishonchli ekanligini ko'rsatuvchi ko'rsatkich.
π Izoh:
Administrative Distance (AD) β bu router turli manbalardan olingan marshrutlar orasidan qaysi biriga ustunlik berishni aniqlash uchun ishlatadigan ishonchlilik ko'rsatkichidir.
Agar bitta tarmoqqa bir nechta routing protokoli orqali yo'l mavjud bo'lsa, router AD qiymati eng kichik bott'lgan marshrutni tanlaydi, chunki u eng ishonchli deb hisoblanadi.

| 9 | Node β tarmoqdagi ma'lumot yuboradigan, qabul qiladigan yoki uzatadigan har qanday qurilma.
Qisqa ta'rif:
A node is any device connected to a network that can send, receive, or forward data.
Misollar:
Kompyuter
Router
Switch
Server
Printer
Telefon
CCNA nuqtai nazaridan, tarmoqqa ulangan har bir qurilma node hisoblanadi.

| 11 |  πHello protokoli β routerlar qo'shnilarini shu orqali topadi va aloqani tirik saqlaydi. OSPF va EIGRP asosida yotadi.
@netadminuz | 284 |
| 12 |  Metric β marshrutlash protokoli eng yaxshi yoβlni tanlashi uchun ishlatiladigan qiymat.
Misollar:
RIP β Hop Count
OSPF β Cost
EIGRP β Composite Metric
Qoida: Metric qancha kichik boβlsa, marshrut shuncha afzal hisoblanadi.

| 13 |  Host route har doim /32 (255.255.255.255) prefiksidan foydalanadi. Bu faqat bitta aniq IP manzilni bildiradi, butun tarmoqni emas.
