The DHCP snooping feature performs the following activities:Validates DHCP messages received from untrusted sources and filters out invalid messages.Rate-limits DHCP traffic from trusted and untrusted sources. • Builds and maintains the DHCP snooping binding database, which contains information about untrusted hosts with leased IP addresses.Utilizes the DHCP snooping binding database to validate subsequent requests from untrusted hosts.Reference: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12-2SX/configuration/guide/book/snoodhcp.pdfQUESTION 86Which switch feature determines validity based on IP-to-MAC address bindings that are stored in a trusted database?A. Dynamic ARP InspectionB. storm controlC. VTP pruningD. DHCP snoopingAnswer: AExplanation:Dynamic ARP inspection determines the validity of an ARP packet based on valid IP-to-MAC address bindings stored in a trusted database, the DHCP snooping binding database. This database is built by DHCP snooping if DHCP snooping is enabled on the VLANs and on the switch. If the ARP packet is received on a trusted interface, the switch forwards the packet without any checks. On untrusted interfaces, the switch forwards the packet only if it is valid.

Host port further divides in two types Isolated port (I-Port) and Community port (C-port). Promiscuous port (P-Port):The switch port connects to a router, firewall or other common gateway device. This port can communicate with anything else connected to the primary or any secondary VLAN. In other words, it is a type of a port that is allowed to send and receive frames from any other port on the VLAN.Host Ports:- Isolated Port (I-Port): Connects to the regular host that resides on isolated VLAN. This port communicates only with P-Ports.- Community Port (C-Port): Connects to the regular host that resides on community VLAN. This port communicates with P-Ports and ports on the same community VLAN. http://en.wikipedia.org/ wiki/Private_VLAN.QUESTION 89When you configure a private VLAN, which type of port must you configure the gateway router port as?A. promiscuous portB. isolated portC. community portD. access portAnswer: AExplanation:There are mainly two types of ports in a Private VLAN: Promiscuous port (P-Port) and Host port. Host port further divides in two types Isolated port (I-Port) and Community port (C-port). Promiscuous port (P-Port):The switch port connects to a router, firewall or other common gateway device. This port can communicate with anything else connected to the primary or any secondary VLAN. In other words, it is a type of a port that is allowed to send and receive frames from any other port on the VLAN.Host Ports:- Isolated Port (I-Port): Connects to the regular host that resides on isolated VLAN. This port communicates only with P-Ports.- Community Port (C-Port): Connects to the regular host that resides on community VLAN. This port communicates with P-Ports and ports on the same community VLAN.http://en.wikipedia.org/wiki/Private_VLANQUESTION 90Which First Hop Redundancy Protocol is an IEEE Standard?A. GLBPB. HSRPC. VRRPD. OSPFAnswer: CExplanation:http://cciethebeginning.wordpress.com/2008/08/23/router-high-availability-protocol-comparison-2/QUESTION 91Refer to the exhibit. Which two statements about SW1 are true? (Choose two) A. InterfaceGi5/1 is using a Cisco proprietary trunking protocolB. On Interface Gi5/1, all untagged traffic is tagged with VLAN 113C. The device is configured with the default MST regionD. Interface Gi5/1 is using an industry-standard trunking protocolE. Interface Gi6/2 is the root port for VLAN 36F. On interface Gi6/2, all untagged traffic is tagged with VLAN 600Answer: CDExplanation:Note: Answer F is not correct because VLAN 600 is the native VLAN on Gi6/2 does not mean untagged traffic is tagged with this VLAN. It only means “all untagged traffic belongs to VLAN 600”.QUESTION 92Refer to the exhibit. Which two commands ensure that DSW1 becomes root bridge for VLAN 10 and 20? (Choose two.) A. spanning-tree mstp 1 priority 0B. spanning-tree mst1 root primaryC. spanning-tree mst vlan 10,20 priority rootD. spanning-tree mst1 priority 4096E. spanning-tree mst1 priority 1F. spanning-tree mstp vlan 10,20 root primaryAnswer: BDQUESTION 93Which gateway role is responsible for answering ARP requests for the virtual IP address in GLBP?A. active virtual forwarderB. active virtual routerC. active virtual gatewayD. designated routerAnswer: CExplanation:GLBP Active Virtual Gateway Members of a GLBP group elect one gateway to be the active virtual gateway (AVG) for that group. Other group members provide backup for the AVG in the event that the AVG becomes unavailable. The AVG assigns a virtual MAC address to each member of the GLBP group. Each gateway assumes responsibility for forwarding packets sent to the virtual MAC address assigned to it by the AVG. These gateways are known as active virtual forwarders (AVFs) for their virtual MAC address. The AVG is responsible for answering Address Resolution Protocol (ARP) requests for the virtual IP address. Load sharing is achieved by the AVG replying to the ARP requests with different virtual MAC addresses.http://www.cisco.com/en/US/docs/ios/12_2t/12_2t15/feature/guide/ft_glbp.htmlQUESTION 94Which VRRP router is responsible for forwarding packets that are sent to the IP addresses of the virtual router?A. virtual router masterB. virtual router backupC. virtual router activeD. virtual router standbyAnswer: AExplanation:VRRP DefinitionsVRRP Router A router running the Virtual Router Redundancy Protocol. It may participate in one or more virtual routers.Virtual Router An abstract object managed by VRRP that acts as a default router for hosts on a shared LAN. It consists of a Virtual Router Identifier and a set of associated IP address(es) across a common LAN. A VRRP Router may backup one or more virtual routers.IP Address Owner The VRRP router that has the virtual router's IP address(es) as real interface address (es). This is the router that, when up, will respond to packets addressed to one of these IP addresses for ICMP pings, TCP connections, etc. Primary IP Address An IP address selected from the set of real interface addresses. One possible selection algorithm is to always select the first address. VRRP advertisements are always sent using the primary IP address as the source of the IP packet.Virtual Router Master The VRRP router that is assuming the responsibility of forwarding packets sent to the IP address(es) associated with the virtual router, and answering ARP requests for these IP addresses.Note that if the IP address owner is available, then it will always become the Master.http://www.ietf.org/rfc/rfc3768.txtQUESTION 95Which command correctly configures standby tracking for group 1 using the default decrement priority value?A. standby 1 track 100B. standby 1 track 100 decrement 1C. standby 1 track 100 decrement 5D. standby 1 track 100 decrement 20Answer: AExplanation:The default decrement value for HSRP standby tracking is 10. There is no need to explicitly state the value if the desired value is the default value.!!!RECOMMEND!!!1.|2018 Latest 300-115 Exam Dumps (PDF & VCE) 478Q Download:https://www.braindump2go.com/300-115.html2.|2018 Latest 300-115 Study Guide Video: YouTube Video: YouTube.com/watch?v=Uf0h4fpiP74 --------------------------------------------------- Images: --------------------------------------------------- --------------------------------------------------- Post date: 2018-04-17 07:48:44 Post date GMT: 2018-04-17 07:48:44 Post modified date: 2018-04-17 07:49:55 Post modified date GMT: 2018-04-17 07:49:55 ____________________________________________________________________________________________ Export of Post and Page as text file has been powered by [ Universal Post Manager ] plugin from www.gconverters.com
