…keeps a translation table keyed on the unique port. In Cisco configuration, inside refers to your network, outside refers to the Internet, and the overload keyword is what turns dynamic NAT …
CCNA · IP Services
A client with no address broadcasts a Discover, servers reply with an Offer, the client broadcasts a Request naming the offer it accepts, and the chosen server sends an Acknowledge with the …
CCNA · Security Fundamentals
A standard ACL, numbered 1 to 99 or 1300 to 1999, matches purely on source IP address, so it should be placed as close to the destination as possible to avoid blocking traffic that was heade…
CCNA · Security Fundamentals
Port security limits which MAC addresses may send on a switch port. When the limit is exceeded, the violation mode decides what happens. Protect silently drops frames from unknown addresses.…
CCNA · Security Fundamentals
DHCP snooping divides switch ports into trusted, normally uplinks toward the real DHCP server, and untrusted, everything facing users. Server messages such as Offer and Ack arriving on untru…
CCNA · Security Fundamentals
WPA2-Personal derives the encryption key from a pre-shared key during a four-way handshake, and anyone who captures that handshake can attempt an offline dictionary attack against the passph…
CCNA · Automation and Programmability
… centralizes the control plane in a controller such as Cisco Catalyst Center or an SD-WAN vManage, leaving devices to forward according to instructions they receive. The southbound interface…
CCNA · Automation and Programmability
…for objects, brackets for lists, and quoted keys. Most Cisco controllers authenticate with a token obtained by a first POST and then presented in a header on later calls. Hook: CRUD spelled …
CCNP-AUTO · Git version control
A commit records a version of the repository and links it to earlier history. A branch is a movable reference that lets work progress separately before integration. Review changes before mer…
CCNP-AUTO · Network automation and APIs
Network automation expresses intended configuration through code or structured requests. Validate inputs, inspect proposed changes and apply them to a limited scope before broad rollout. Sto…
CCNP-AUTO · Delivery pipelines
A delivery pipeline automates build, validation and release steps. Keep the artifact traceable to its source and test results, and promote the intended version through environments. Protect …
CCNP-COLLAB · Network protection
A network rule should express a justified communication path with the necessary source, destination, protocol and service. Segmentation limits how far a compromise can spread, but only when …
CCNP-COLLAB · Network troubleshooting
Network troubleshooting narrows the boundary between success and failure. Compare affected and unaffected devices, then examine link state, addressing, routes, name resolution and the applic…
CCNP-COLLAB · IP routing
A router compares a packet's destination with its routing table and selects the most specific matching prefix before resolving other preferences among equivalent routes. A default route is u…
CCNP-CYBER · Detection engineering and validation
This concept review develops the reasoning needed for detection engineering and validation. Start by identifying the relevant assets, permissions, evidence and trust boundaries. Distinguish …
CCNP-CYBER · Incident response
Containment limits ongoing damage, while eradication removes the cause and recovery restores trusted operation. These activities may overlap as new evidence appears. Preserve useful evidence…
CCNP-CYBER · Traffic analysis
A packet capture records traffic visible at a particular point, so its location and timing affect what it can prove. Follow the conversation across requests, responses, retransmissions and r…
CCNP-DC · Data center networking
Data-center networks connect compute and storage across many links and devices. Redundant paths improve resilience when forwarding, loop prevention and failover work together. Consider east-…
CCNP-DC · Storage concepts
Block storage presents volumes to an operating system, file storage organizes shared files and directories, and object storage addresses objects with metadata. The workload determines which …
CCNP-DC · Virtualization operations
A hypervisor lets several virtual machines share a host while each runs its own operating system. The workloads still compete for physical CPU, memory, storage and network capacity. Investig…
