What is LLDP on a Cisco switch?

CORRECT ANSWER-Link Layer Discovery Protocol. OSI layer 2 open standard discovery protocol that is used to facilitate interoperability between Cisco devices and non-Cisco devices. Attributes that can be learned from neighboring devices contain Type, Length, Value (TLV) info including port description, system description and management address. What is VTP?
CORRECT ANSWER-VLAN Trunking Protocol (VTP) is a Layer 2 messaging protocol that maintains VLAN configuration consistency throughout a common administrative domain by managing VLAN additions, deletions, and name changes across multiple switches. Without VTP, you would have to manually add VLAN information to each switch in the network. What is CDP?

CORRECT ANSWER-Software basically. (previously known as Hybrid Remote Edge Access Point or H-REAP) is a wireless solution for branch office and remote office deployments. It enables customers to configure and control access points (AP) in a branch or remote office from the corporate office through a wide area network (WAN) link without deploying a controller in each office. The FlexConnect access points can switch client data traffic locally and perform client authentication locally when their connection to the controller is lost. When they are connected to the controller, they can also

send traffic back to the controller. In the connected mode, the FlexConnect access point can also perform local authentication. Number of host on a /24 and it subnet mask

What is PPP?

CORRECT ANSWER-Point-to-Point Protocol (PPP) is a Data Link layer protocol that can be used over either asynchronous serial (dial-up) or synchronous serial (ISDN) media. It uses Link Control Protocol (LCP) to build and maintain data-link connections. Network Control Protocol (NCP) is used to allow multiple Network layer protocols (routed protocols) to be used on a point- to-point connection. The basic purpose of PPP is to transport layer 3 packets across a Data Link layer point-to-point link, and it's nonproprietary. The PPP protocol stack is specified at the Physical and Data Link layers only. In 802.11 wireless topology, what is BSS in Infrastructure?
CORRECT ANSWER-Basic Service Set; Consist of a single AP interconnecting all associated wireless clients. The radius of which it covers in it wireless range is called a Basic Service Area (BSA). Layer 2 MAC address of the AP is used to uniquely ID each BSS which is called a Basic Service Set Identifier (BSSID). In 802.11 wireless topology, what is ESS in infrastructure?
CORRECT ANSWER-Extended Service Set ESS is ID by a SSID and each BSS is ID by its BSSID. When you need more coverage, two or more BSS can join through a common distribution system (DS) into an ESS. The whole covered area is called an Extended Service Area (ESA). A client in one BSA can now communicate with other clients in another BSA within the same ESS. Like a roaming cell phone user may move from one BSA to another and it would be seamless Since WLAN are half-duplex, what do we use to avoid collision?
CORRECT ANSWER-(CSMA/CA) carrier sense multiple access with collision avoidance.

Cisco proprietary
Can convey VTP information Characteristics of LLDP?
CORRECT ANSWER--30 second update frequency
120 second hold timer
disabled by default
L2 protocol
Open standard protocol What is the default mode of VTP when on a new switch?
CORRECT ANSWER-Server mode What is EIGRP?
CORRECT ANSWER-Enhanced Interior Gateway Routing Protocol. Is an advanced distance vector routing protocol. EIGRP supports classless routing and VLSM, route summarization, incremental updates, load balancing and many other useful features. It is a Cisco proprietary protocol, so all routers in a network that is running EIGRP must be Cisco routers.

CORRECT ANSWER-Cost What metric does RIP use to calculate best path?
CORRECT ANSWER-Hop count How do you untag a VLAN?
CORRECT ANSWER-You set it as a native VLAN What is RFC 1918?
CORRECT ANSWER-RFC 1918 is Address Allocation for Private Internets The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private Internets: 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/ What is Cisco ACI?
CORRECT ANSWER-Application Centric Infrastructure What layer is MPLS considered and what does it stand for?
