CCNA Security, Automation, and Protocols Flashcards

FrontBack
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
Command to verify SSH version?show ip ssh
What is a virtual LAN (VLAN) trunking protocol?802.1Q
Default port for SNMP?Port 161
