Refer to the exhibit．A problem with network connectivity has been observed．It is suspected that the cable connected to switch port Fa0/9 on Switch 1 disconnected．What would be an effect of tis cable being disconnected? [*] Host B would not be able to access the server in VLAN9 until the cable is reconnected For less than a minute ,Host B would not be able to access the server in VLAN9．Then normal network function would resume． Communication between VLAN3 and the other VLANs would be disabled The transfer of files from Host B to the server in VLAN9 would be significantly slower．

Users have been complaining that their Frame Relay connection to the corporate site is very slow． The network administrator suspects that the link is overloaded． Based on the partial output of the Router#show frame relay pvccommand shown in the graphic, which output value indicates to the local router that traffic sent to the corporate site is experiencing congestion? [*] DLCI = 100 last time PVC status changed 00:25:40 in BECN packets 192 in FECN packets 147 in DE packets 0

What occurs on a Frame Relay network when the CIR is exceeded? All TCP traffic is marked discard eligible． All UDP traffic is marked discard eligible and a BECN is sent． All TCP traffic is marked discard eligible and a BECN is sent． All traffic exceeding the CIR is marked discard eligible．

Router A is unable to reach Router B．Both routers are running ios version 12．0．After reviewing the command output and graphic,what is the most likely cause of the problem? [*] incorrect bandwidth configuration incorrect LMI configuration incorrect map statement incorrect IP address

Refer to the exhibit． What is the meaning of the term dynamic as displayed in the output of the show frame-relay map command shown? [*] The Serial0/0 interface is passing traffic． The DLCI 100 was dynamically allocated by the router The Serial0/0 interface acquired the IP address of 172．16．3．1 from a DHCP server The DLCI 100 will be dynamically changed as required to adapt to changes in the Frame Relay cloud The mapping between DLCI 100 and the end station IP address 172．16．3．1 was learned through Inverse ARP

Which are three reasons that an organization with multiple branch offices and roaming users might implement a Cisco VPN solution instead of point-to-point WAN links? reduced cost better throughput increased security scalability reduced latency

Which statement is correct regarding the operation of DHCP? A DHCP client uses a ping to detect address conflicts． A DHCP server uses a gratuitous ARP to detect DHCP clients． A DHCP client uses a gratuitous ARP to detect a DHCP server． If an address conflict is detected, the address is removed from the pool and an administrator must resolve the conflict． If an address conflict is detected, the address removed from the pool for an amount of time configurable by the administrator．

Refer to the exhibit．HostA cannot ping Host B．Assuming routing is properly configured,what could be the cause of this problem? [*] HostA is not on the same subnet as its default gateway The address of SwitchA is a subnet address The Fa0/0 interface on RouterA is on a subnet that cannot be used The serial interfaces of the routers are not on the same subnet The Fa0/0 interface on RouterB is using a broadcast address

What two statistics appear in show frame-relay map output? The number of FECN packets that are received by the router The number of BECN packets that are received by the router． The ip address of the local router The value of the local DLCI The status of the PVC that is configured on the router

Which protocol is an open standard protocol framework that is commonly used in VPNs,to provid secure end-to-end communication? L2TP IPsec PPTP RSA

Which encapsulation type is a Frame Relay encapsulation type that is supported by Cisco routers? IETF HDLC Q9333-A Annex A ANSI Annex D

which command allows you to verify the encapsulation type (CISCO OR IETF) for a frame relay link? show frame-relay map show frame-relay lmi show inter serial show frame-relay pvc

The output of the show frame-relay pvc command shows “PVC STATUS=INACTIVE“． What does this mean? The PVC is configured correctly and is operating normally, but no data packets have been detected for more than five minutes． The PVC is configured correctly, is operating normally, and is no longer actively seeking the address the remote route． The PVC is configured correctly, is operating normally, and is waiting for interesting to trigger a call to the remote router． The PVC is configured correctly on the local switch, but there is a problem on the remote end of the PVC． The PVC is not configured on the switch．

The command frame-relay map ip 10．121．16．8 102 broadcast was entered on the router．Which of the following statement is true concering this command? The broadcast option allows packets,such as RIP updates,to be forwarded access the PVC． The command shoud be executed from the goble configuration mode． 102 is he remote DLCI that will recive the information． The ip address 10．121．16．8 is the local router port used to forward date． This command is required for all Frame Rely configurations

Refer to the exhibit． An administrator pings the default gateway at 10．10．10．1 and sees the output as shown． At which OSI layer is the problem? [*] data link layer application layer access layer session layer network layer

Refer to the exhibit． A network administrator attempts to ping Host2 from Host1 and receives the result that are shown． What is a possible problem? [*] The link between Host1 and Switch1 is down． TCP/IP is not functioning on Host1． The link between Router1 and Router2 is down． The default gateway on Host1 is incorrect． Interface Fa0/0 on Router1 is shudown．

Refer to the exhibit．A problem with network connectivity has been observed．It is suspected that the cable connected to switch port Fa0/9 on Switch 1 disconnected．What would be an effect of tis cable being disconnected? [*] Host B would not be able to access the server in VLAN9 until the cable is reconnected For less than a minute ,Host B would not be able to access the server in VLAN9．Then normal network function would resume． Communication between VLAN3 and the other VLANs would be disabled The transfer of files from Host B to the server in VLAN9 would be significantly slower．

Refer to the exhibit． The network shown in the diagram is experiencing connectivity problems． Which of the following will correct the problems? [*] Configure the gateway on Host A as 10．1．1．1． Configure the gateway on Host B as 10．1．2．254． Configure the IP address of Host A as 10．1．2．2． Configure the IP address of Host B as 10．1．2．2． Configure the masks on both hosts to be 255．255．255．224．

Refer to the exhibit． Host in network 192．168．2．0 are unable to reach hosts in network 192．168．3．0． Based on the output from RouterA, what are two possible reasons for the failure? [*] The cable that is connected to S0/0 on RouterA is faulty． Interface S0/0 on RouterB is administratively down． Interface S0/0 on RouterA is configured with an incorrect subnet mask． The encapsulation that is configured on S0/0 of RotuerB does not match the encapsulation that is configured on S0/0 of RouterA． Interface S0/0 on RouterA is not receiving a clock signal from the CSU/DSU．
