CCNA Security, Automation, and Protocols Flashcards
Front | Back |
Primary purpose of 802.1X? | Port-based access control |
What does SNMP stand for? | Simple Network Management Protocol |
What is the primary purpose of EIGRP? | Internal gateway routing |
Key difference between RADIUS and TACACS+? | RADIUS combines authentication and authorization; TACACS+ separates them |
Primary purpose of 802.11 standards? | Wireless LAN communications |
Default Hello interval for OSPF? | 10 seconds |
Default Dead interval for OSPF? | 40 seconds |
What protocol does SYSLOG use? | UDP (usually on port 514) |
Protocol used to synchronize device clocks? | NTP (Network Time Protocol) |
Protocol used for network automation? | RESTCONF or NETCONF |
What is a BPDU? | Bridge Protocol Data Unit |
Command to view NAT statistics? | show ip nat statistics |
Default administrative distance of OSPF? | 110 |
What is RSTP? | Rapid Spanning Tree Protocol |
Protocol that encrypts web traffic? | HTTPS |
Command to generate cryptographic keys for SSH? | crypto key generate rsa |
What port does HTTPS use? | Port 443 |
Command to enable IPv6 on a router? | ipv6 enable |
What does PoE stand for? | Power over Ethernet |
Purpose of HSRP? | Provides gateway redundancy |
Difference between standard and extended ACLs? | Standard ACLs filter by source IP; extended ACLs filter by source/destination and protocol |
Default administrative distance of EIGRP? | 90 |
Automation tool commonly used with Cisco devices? | Ansible |
Primary difference between IPv4 and IPv6 addressing? | IPv6 uses 128-bit addresses; IPv4 uses 32-bit addresses |
Protocol used for securing communication between devices? | IPSec |
Purpose of a wildcard mask in ACLs? | Specifies IP ranges for filtering |
Purpose of PortFast in STP? | Allows a port to bypass listening/learning states |
Protocol that replaces Telnet for secure remote management? | SSH |
Protocol to prevent rogue DHCP servers? | DHCP Snooping |
Protocol that prevents switching loops? | Spanning Tree Protocol (STP) |
Command to enable BPDU Guard on an interface? | spanning-tree bpduguard enable |
What does AAA stand for in network security? | Authentication, Authorization, Accounting |
Tools for multi-device automation workflows? | Python or Ansible |
Command to enable DHCP Snooping on a switch? | ip dhcp snooping |
Role of a Next-Hop in routing? | Indicates where to send a packet next |
Role of TACACS+ in a network? | Centralized authentication and authorization |
Command to enable HTTPS access to a device? | ip http secure-server |
