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 is removed from the pool for an amount of time configurable by the administrator. If an address conflict is detected, the address is removed from the pool and will not be reused until the server is rebooted.
If a conflict is detected, the address is removed from the pool. The address will not be assigned until the administrator resolves the conflict. Statements A, B, C, and D of ACL 10 have been entered in the shown order and applied to interface E0 inbound, to prevent all hosts except those whose addresses are the first and last IP of subnet But as is, the ACL does not restrict anyone from the network.
How can the ACL statements be re-arranged so that the system works as intended? ACDB B. BADC C.

DBAC D. Answer: D Explanation: Routers go line by line through an access list until a match is found and then will not look any further, even if a more specific of better match is found later on in the access list. So, it it best to begin with the most specific entries first, in this cast the two hosts in line C and D. Then, include the subnet B and then finally the rest of the traffic A. 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 of the remote router.
The PVC is configured correctly, is operating normally, and is waiting for interesting traffic to trigger a call to the remote router. The PVC is not configured on the local switch. There are 4 statuses: 1.

This status is rarely seen so it is ignored in some books. Router config-if ppp authentication chap fallback ppp B. Router config-if ppp authentication chap pap C.
Router config-if authentication ppp chap fallback ppp D. Router config-if authentication ppp chap pap. Answer: C Explanation: IPSec is a framework of open standards that provides data confidentiality, data integrity, and data authentication between participating peers at the IP layer. PPP was originally emerged as an encapsulation protocol for transporting IP traffic between two peers.
It is a data link layer protocol layer 2 in the OSI model. Which of the following statements is true concerning this command? This command should be executed from the global configuration mode. The IP address This command is required for all Frame Relay configurations. Answer: E Explanation: Broadcast is added to the configurations of the frame relay, so the PVC supports broadcast, allowing the routing protocol updates that use the broadcast update mechanism to be forwarded across itself.
Choose two. PPP B.

WAP C. DSL D. L2TPv3 E. It is a data link layer protocol used for WAN connections. Answer: B Explanation: PPP: Provides router-to-router and host-to-network connections over synchronous and asynchronous circuits. PPP was designed to work with several network layer protocols, including IP.

Both routers are running IOS version After reviewing the command output and graphic, what is the most likely cause of the problem? Answer: C Explanation: First we have to say this is an unclear question and it is wrong.
But we guess there is a typo in the output. What is the meaning of the term dynamic as displayed in the output of the show frame-relay map command shown?
The DLCI was dynamically allocated by the router. Dynamic address mapping is enabled by default for all protocols enabled on a physical interface.
Therefore, no static address mapping is required. The router at the remote office is a non-Cisco router.
How should the network administrator configure the serial interface of the main office router to make the connection? Answer: B Explanation: With serial point to point links there are two options for the encapsulation. The other option is PPP which is standards based and supported by all vendors.
Choose three. These include reduced cost, increased security since all traffic is encrypted, and increased scalability as single WAN link can be used to connect to all locations in a VPN, where as a point to point link would need to be provisioned to each location. The network administrator suspects that the link is overloaded.
Based on the partial output of the Router show frame relay pvc command shown in the graphic, which output value indicates to the local router that traffic sent to the corporate site is experiencing congestion?
Answer: C Explanation: If device A is sending data to device B across a Frame Relay infrastructure and one of the intermediate Frame Relay switches encounters congestion, congestion being full buffers, over-subscribed port, overloaded resources, etc. Check the encapsulation type on the Cisco device with the show frame-relay map exec command.
Which of the following procedures are required to accomplish this task? Remove the IP address from the physical interface. Encapsulate the physical interface with multipoint PPP. Create the virtual interfaces with the interface command. Configure each subinterface with its own IP address.
Disable split horizon to prevent routing loops between the subinterface networks. Configure static Frame Relay map entries for each subinterface network.

Each subinterface will then have its own IP address, and no IP address will be assigned to the main interface. All TCP traffic is marked discard eligible. All traffic exceeding the CIR is marked discard eligible.

Frames that are sent in excess of the CIR are marked as discard eligible DE which means they can be dropped if the congestion occurs within the Frame Relay network. Note: In the Frame Relay frame format, there is a bit called Discard eligible DE bit that is used to identify frames that are first to be dropped when the CIR is exceeded.
CHAP uses a two-way handshake. CHAP uses a three-way handshake. CHAP authentication periodically occurs after link establishment. CHAP authentication passwords are sent in plaintext. CHAP authentication is performed only upon link establishment.
CHAP has no protection from playback attacks. CHAP periodically verifies the identity of the client by using a three-way handshake. This happens at the time of establishing the initial link LCP , and may happen again at any time afterwards.
