Lab Track
Build-order labs from cabling to REST calls. Run them in Packet Tracer (or CML), then tap the status here — done labs pay 60 XP. Community .pkt files: learn-skillnuggets/CCNA-Packet-Tracer and O2sa/CCNA-Labs on GitHub.
Hostname, banners, enable secret, console + VTY passwords, service password-encryption.
Create SALES and ENG VLANs, assign access ports, verify with show vlan brief.
Trunk two switches, set a dedicated native VLAN, prune allowed VLANs.
Subinterfaces with dot1q encapsulation routing between VLANs.
ip routing, SVIs per VLAN, routed uplink — the modern inter-VLAN pattern.
Force the root bridge, enable PortFast + BPDU Guard on edge ports.
Bundle two links active/passive, confirm with show etherchannel summary.
IPv4 statics, a floating backup, and a default route to the edge.
Area 0 across three routers, passive interfaces, verify neighbors and LSDB.
IOS DHCP pool, exclusions, ip helper-address from a remote subnet.
Inside/outside marking, PAT overload to one public IP, verify translations.
Filter by source, then by protocol/port; place them where they belong.
Domain name, RSA keys, local user, transport input ssh on the VTY lines.
Sticky MACs on access ports, snooping with a trusted uplink.
Sync clocks to an NTP source, timestamp logs, ship them to a syslog host.
GET device facts from a sandbox (RESTCONF or Meraki) with Postman or Python requests.
