  • 1. Which mechanism is used to create a floating static route? administrative distance cost hop count passive interface Scoring Rule For: correctness of response 2 points for Option 1 0 points for any other option Max Value = 2 IPSec operates at which layer of the OSI model? application network datalink transport Scoring Rule For: correctness of response 2 points for Option 2 0 points for any other option Max Value = 2 Which is true regarding Frame Relay LMI? There are three LMI types standardized by ANSI, ITU-T, and Cisco. Routers at each end of a Frame Relay virtual circuit must always use the same LMI type. The LMI type must be manually configured. The only function of LMI is to verify the connection between the router and the Frame Relay switch. Scoring Rule For: correctness of response 2 points for Option 1 0 points for any other option Max Value = 2 Which statement identifies the IP address design for subinterfaces that are configured for a Frame Relay network? Multipoint configurations require the IP address of each subinterface on each router to be
  • 2. in its own subnet. Multipoint configurations require IP addresses for each subinterface on each router to be a part of the same subnet. Point-to-point configurations require IP addresses for each subinterface on each router to be a part of the same subnet. Point-to-point configurations do not require IP addresses on each subinterface on each router. Multipoint configurations do not require IP addresses on each subinterface on each router. Scoring Rule For: correctness of response 2 points for Option 2 0 points for any other option Max Value = 2 Which three algorithms can be used to encrypt user data in an IPSec VPN framework? (Choose three.) 3DES AES Diffie-Hellman DES ESP SHA Scoring Rule For: correctness of response Option 1, Option 2, and Option 4 are correct. 1 point for each correct option. 0 points if more options are selected than required. Max Value = 3 Which flag is set by a Frame Relay switch to inform the receiving station that congestion was experienced? BECN DE FECN FCS
  • 3. Scoring Rule For: correctness of response 2 points for Option 3 0 points for any other option Max Value = 2 Refer to the exhibit. The complete configuration of a Frame Relay interface on the Chicago router is shown. How does the Chicago router know which DLCI is mapped to the IP address of the remote router? DE CIR FECN Inverse ARP Scoring Rule For: correctness of response 2 points for Option 4 0 points for any other option Max Value = 2 What statement correctly defines the purpose of the split horizon rule? marks the route unreachable in a routing update that is sent to other routers prevents routers from advertising a network through the interface from which the update came prevents routers from accepting higher cost routes to networks previously marked as inaccessible before the timer expires limits the number of hops a packet can traverse through the network before it should be discarded Scoring Rule For: correctness of response 2 points for Option 2 0 points for any other option Max Value = 2 Which PVC status suggests that the router recognizes the DLCI configured on its interface as being present on the Frame Relay switch, but the PVC associated with the DLCI is not capable of end-to-end communication? active deleted
  • 4. inactive idle Scoring Rule For: correctness of response 2 points for Option 3 0 points for any other option Max Value = 2 Refer to the exhibit. Which router command is used to associate a Layer 2 address with the corresponding Layer 3 address? Miller(config-if)#frame-relay map ip 172.16.150.1 110 Miller(config-if)#frame-relay map ip 172.16.150.1 112 Miller(config-if)#frame-relay map ip 172.16.150.2 110 Miller(config-if)#frame-relay map ip 172.16.150.2 112 Scoring Rule For: correctness of response 2 points for Option 3 0 points for any other option Max Value = 2 A network administrator issued the command show frame-relay pvc. The response from the router shows the status of a PVC as deleted. What is the reason for this status? The DLCI is using the wrong LMI type. The DLCI is usable but has little activity. The DLCI is programmed in the switch but the circuit is not usable. The DLCI configured on the CPE device does not match the DLCI. Scoring Rule For: correctness of response 2 points for Option 4 0 points for any other option Max Value = 2 What is one benefit of using a network simulation software package? The network design can be tested before it is actually implemented. Simulation software packages are quickly updated to support new network technologies and devices. Simulated devices have the same features as actual devices, allowing for detection of all potential problems. Software packages can simulate all possible network traffic conditions, giving an accurate
  • 5. prediction of network performance. Scoring Rule For: correctness of response 2 points for Option 1 0 points for any other option Max Value = 2 What are two components a network designer considers when planning a VPN? (Choose two.) encryption algorithm for privacy and security encapsulation protocol to use when creating the VPN tunnel switching technology to optimize VPN WAN throughput tunneling technology for guarding against data corruption routing protocol on the gateway for optimum performance Scoring Rule For: correctness of response Option 1 and Option 2 are correct. 1 point for each correct option. 0 points if more options are selected than required. Max Value = 2 When identifying VPN requirements for endpoint users, what care must be taken to protect the network when remote users log in from unsecured public locations? Ensure that the user has VPN client software that allows access to all internal resources. Ensure that the VPN user traffic does not slow down internally sourced traffic on the network. Ensure that there are no obstacles to hamper the users from accessing all internal resources. Ensure that remote users can only access network resources that are appropriate to their job function. Scoring Rule For: correctness of response 2 points for Option 4 0 points for any other option Max Value = 2
  • 6. Which two components are key elements when implementing a VPN? (Choose two.) concentration encryption prioritization compression encapsulation Scoring Rule For: correctness of response Option 2 and Option 5 are correct. 1 point for each correct option. 0 points if more options are selected than required. Max Value = 2 What tool can help ease the configuration of VPN servers on routers? Cisco SDM PIX Firewall Cisco VPN Concentrator Cisco Adaptive Security Appliances Scoring Rule For: correctness of response 2 points for Option 1 0 points for any other option Max Value = 2 What is used to identify the path to the next frame-relay switch in a Frame Relay network? CIR DLCI FECN BECN Scoring Rule For: correctness of response 2 points for Option 2 0 points for any other option Max Value = 2 Which two statements are true regarding VPN security? (Choose two.) Users may only establish a VPN connection from secure locations and never from public areas. Users that connect to a network through a VPN do not have to log in to resources on the network. Users that connect to a network through a VPN are are considered trusted users on the
  • 7. network. Users may establish a VPN connection from unsecure locations such as airports and hotel lobbies. Users that connect to a network through a VPN should have access to all the resources on the network. Scoring Rule For: correctness of response Option 3 and Option 4 are correct. 1 point for each correct option. 0 points if more options are selected than required. Max Value = 2 Refer to the exhibit.
