ccna 200-301 exam description.Random-access memory (RAM ) This is a volatile memory that can be read and written to by the microprocessor.Rapid Spanning Tree Protocol (RSTP) An improved version of STP defined by IEEE802.1W that provides faster and more consistent convergence than STP (802.1d).Regional Internet Registry (RIR) This term refers to the five major organizations currently responsible for allocating public and globally unique IPv4 and IPv6 address space.RegistryPrefix In IPv6, this prefix describes a public, globally unique block of IPv6 addresses that is assigned by ICANN to a Regional Internet Registry.NotifiedDistance From the perspective of the _EIGRP router, the subnet metric is computed on one neighboring router and communicated to the first router in a routing change.to the first router in a routing change.ReverseRoute From the perspective of a host, the route through which a packet is transmitted for the packet to be sent from another host back to this host.Routing Information Protocol (RIP) An interior gateway protocol (IGP) that uses distance vector logic and router hops as a metric. RIP version 1 (RIP-1) is rarely used today, and RIP version 2 (RIP-2) offers additional features, including support for VLSM.Read-only memory (ROM) is a non-volatile memory that can only be read but not written to by the microprocessor.ROMMonitor (ROMMON) This is a low-grade operating system that can be loaded into Cisco routers to perform several less common maintenance tasks, including password recovery.
