Question 1: EIGRP
Answer:
Enhanced Interior Gateway Routing Protocol. An advanced version of IGRP developed by Cisco.Provides superior convergence properties and operating efficiency and combines the advantages of link-state protocols with those of distance vector protocols.
Question 2: ISL
Answer:
Inter-switch link. A Cisco proprietary method of tagging frames and passing over a trunk link. A VLAN trunking protocol. Now obsolete over IEEE 802.1Q.
Question 3: DRAM
Answer:
Dynamic Random Access Memory. Dynamic RAM. The slowest type of RAM, which requires frequent electrical refreshes to keep contents valid.
Question 4: IGRP
Answer:
Interior Gateway routing Protocol (IGP) developed by Cisco to address the issues associated with routing in large networks. It was designed to overcome the limitations of RIP and RIPv2
Question 5: OSPFv3
Answer:
Version 3 of the OSPF routing protocol. It is used to support both IPv4 and IPv6 unicast address families.
Question 6: MS-CHAPv2
Answer:
Microsoft Challenge Handshake Authentication Protocol, version
- An authentication protocol provided with Windows operating systems that follows the CHAP model,
but uses stronger encryption, uses different encryption keys for transmission and reception, and requires mutual authentication between two computers.
Question 7: LAG
Answer:
Link aggregation group. As defined by the IEEE 802.3ad standard, link aggregation allows multiple physical connections to be logically bundled into a single logical connection.
Question 8: DHCP
Answer:
(Dynamic Host Configuration Protocol) A set of rules that allow network client computers to find and use the Internet address that corresponds to a domain name. A program that leases out an IP address.
Question 9: GCMP or GCM
Answer:
Galois/Counter mode protocol. A mode that starts with CTR mode, but adds a special data type known as a Galois field to add integrity. More secure than CCMP. AES counter mode encryption. Galois message authentication code (GMAC) used as a message integrity check MIC. Used in WPA3
Question 10: PAgP
Answer:
Port Aggregation Protocol (PAgP) is a messaging protocol defined by Cisco which enables two neighboring devices to realize that they have multiple parallel links connecting to each other, and then to decide which links can be combined into an EtherChannel.
Question 11: HDLC
Answer:
High-Level Data Link Control. A bit-oriented synchronous data link layer (layer 1) protocol developed by the International Organization for Standardization (ISO). Used for leased lines with data recovery.
Question 12: DTP
Answer:
Dynamic Trunk Protocol. Cisco Proprietary Protocol designed to automatically negotiate trunking between two switches
Question 13: RP
Answer:
Root ports. Switch ports closest to the root bridge.
Question 14: AS
Answer:
Authentication server. A server that keeps track of who is logging on to the network and which services on the network are available to each user
Question 15: CIDR
Answer:
Classless Inter-Domain Routing. I reference to to a prefix or a prefix mask. It can also be called a CIDR mask or a slash mask. i.e. /8 or /24
Question 16: TKIP
Answer:
Temporal Key Integrity Protocol. Wireless security protocol introduced to address the problems with WEP. TKIP was used with WPA but many implementations of WPA now support CCMP. Obsolete
Question 17: NA
Answer:
Neighbor Advertisement (. A message defined by the IPv6 Neighbor Discovery Protocol (NDP), used to declare to other neighbors a host's MAC address. Sometimes sent in response to a previously received NDP Neighbor Solicitation (NS) message.
Question 18: RIPv2
Answer:
The current version of RIP. Fixed many problems of RIPv1, but the maximum hop count of 15 still applies. (Ospf and eigrp are still better though)
Question 19: MPBGP
Answer:
Multiprotocol BGP. A particular set of BGP extensions that allows BGP to support multiple address families, which when used to create an MPLS VPN service gives the SP the method to advertise the IPv4 routes of many customers while keeping those route advertisements logically separated.
Question 20: RPVST+
Answer:
Rapid Per-VLAN Spanning Tree Plus. A Cisco implementation of RSTP. It supports one instance of RSTP for each VLAN.
Question 21: EAP-TLS
Answer:
Extensible Authentication Protocol-Transport Layer Security. Considered to be the most secure wireless authentication method available. Client and AS authenticated by digital certificate.
Question 22: SPF
Answer:
shortest path first. A type of routing algorithm that process the LSDB which is a compilation of the LSAs.The only true SPF protocol is Open Shortest Path First (OSPF).
Question 23: RS
Answer:
Router Solicitation. A message defined by the IPv6 Neighbor Discovery Protocol (NDP), used to ask any routers on the link to reply, identifying the router, plus other configuration settings (prefixes and prefix lengths).
Question 24: FCS
Answer:
the frame check sequence is an error detection mechanism found in the L2 trailer. Check sum.
