Cisco CCNA 200-301 Flashcards
| Front | Back |
| Automation tool commonly used with Cisco devices? | Ansible |
| Command to enable BPDU Guard on an interface? | spanning-tree bpduguard enable |
| Command to enable DHCP Snooping on a switch? | ip dhcp snooping |
| Command to enable HTTPS access to a device? | ip http secure-server |
| Command to enable IPv6 on a router? | ipv6 enable |
| Command to generate cryptographic keys for SSH? | crypto key generate rsa |
| Command to verify SSH version? | show ip ssh |
| Command to view NAT statistics? | show ip nat statistics |
| Default administrative distance of EIGRP? | 90 |
| Default administrative distance of OSPF? | 110 |
| Default Dead interval for OSPF? | 40 seconds |
| Default Hello interval for OSPF? | 10 seconds |
| Default port for SNMP? | Port 161 |
| Difference between standard and extended ACLs? | Standard ACLs filter by source IP; extended ACLs filter by source/destination and protocol |
| Key difference between RADIUS and TACACS+? | RADIUS combines authentication and authorization; TACACS+ separates them |
| Primary difference between IPv4 and IPv6 addressing? | IPv6 uses 128-bit addresses; IPv4 uses 32-bit addresses |

| Protocol to prevent rogue DHCP servers? | DHCP Snooping |
| Protocol used for network automation? | RESTCONF or NETCONF |
| Protocol used for securing communication between devices? | IPSec |
| Protocol used to synchronize device clocks? | NTP (Network Time Protocol) |
| Purpose of a wildcard mask in ACLs? | Specifies IP ranges for filtering |
| Purpose of HSRP? | Provides gateway redundancy |
| Purpose of PortFast in STP? | Allows a port to bypass listening/learning states |
| Role of a Next-Hop in routing? | Indicates where to send a packet next |
| Role of TACACS+ in a network? | Centralized authentication and authorization |
| Tools for multi-device automation workflows? | Python or Ansible |
| What does AAA stand for in network security? | Authentication, Authorization, Accounting |
