Exam Prep Questions

Question 1

Your company requires 800 LAN-to-LAN sessions. What model of concentrator should you provide at the main office? (Choose two.)

  1. Cisco 3060 VPN Concentrator

  2. Cisco 3030 VPN Concentrator

  3. Cisco 3080 VPN Concentrator

  4. Cisco 3800 VPN Concentrator

Answers A and C are correct. The VPN 3060 and 3080 Concentrators handle up to 1,000 LAN-to-LAN sessions. B is incorrect because the 3030 VPN Concentrator supports 500 LAN-to-LAN sessions. D is incorrect because there is no such model as the 3800 VPN Concentrator.

Question 2

What are the standard SEP and SRAM amounts in the 3030 Concentrator?

  1. 2 SEP, 128MB of SRAM

  2. 1 SEP, 64MB of SRAM

  3. 0 SEP, 128MB of SRAM

  4. 1 SEP, 128MB of SRAM

Answer D is correct. The 3030 Concentrator comes with 1 SEP module for hardware encryption and 128MB of SRAM. Answer A is incorrect because the standard 3030 Concentrator ships with only one SEP module. Answer B is incorrect because the 3030 Concentrator comes with 128MB of SRAM. Answer C is incorrect because the VPN 3030 comes with one SEP module.

Question 3

What are the two modes of 3002 Hardware Client? (Choose two.)

  1. Network Extension mode

  2. Network bridge mode

  3. Software mode

  4. Client mode

Answers A and D are correct. The 3002 Hardware Client utilizes Client mode with PAT support to hide the clients behind the device, and Network Extension mode, which connects the two networks and does not hide the end-devices. Answers B and C are incorrect because network bridge mode and software mode do not exist.

Question 4

Which of the following are not upgradeable?

  1. Cisco VPN 3005 Concentrator

  2. Cisco VPN 3015 Concentrator

  3. Cisco VPN 3030 Concentrator

  4. Cisco VPN 3060 Concentrator

Answer A is correct. The VPN 3005 is a fixed design and cannot be upgraded. Answers B, C, and D are incorrect because they all share a similar chassis, which can be upgraded with up to four SEP modules.

Question 5

Which protocol is utilized for concentrator redundancy?

  1. VCA

  2. VAC

  3. VRRP

  4. HSRP

Answer C is correct. Concentrators use VRRP to enable redundancy, among other parallel concentrators. Answer A is incorrect because VCA is a protocol utilized for load balancing. Answer B is incorrect because VAC is an accelerator card for PIX firewalls. D is incorrect because HSRP is a redundancy protocol utilized by Cisco routers, not Cisco VPN Concentrators.

Question 6

The 3080 Concentrator's top and bottom left modules fail. What happens to the existing sessions when the unit offloads the sessions to the correct SEPs?

  1. They are automatically reconnected.

  2. This functionality does not exist.

  3. They are lost and need to be reconnected.

  4. Only LAN-to-LAN sessions are saved.

Answer C is correct. When two SEP modules fail in the same column, the sessions are lost and have to be rebuilt. Answer A is incorrect because this happens only when the top SEP fails. Answer B is incorrect because SEP redundancy exists and is automatically running on models 3015 and higher. Answer D is incorrect because all sessions are lost—remote access as well as LAN-to-LAN.

Question 7

Your standard 3015 Concentrator's top SEP module fails. What happens to the existing sessions?

  1. The redundant SEP module resumes the sessions.

  2. This functionality does not exist.

  3. All sessions are lost and users will not be able to connect because the only SEP module has failed.

  4. Users need to reconnect their sessions, which the concentrator's software will encrypt.

Answer D is correct. When all SEP modules fail, the concentrator's software encrypts subsequent sessions. Answer A is incorrect because the 3015 does not come with a redundant SEP. Answer B is incorrect because SEP redundancy exists and is automatically running on models 3015 and higher. C is incorrect because subsequent sessions are handled via the concentrator's software.

Question 8

Your company has decided to use the VPN 3000 Concentrator for its enterprise headquarters. The company consists of roughly 9,000 sales employees, who typically travel to customers' locations or are working from home. Because this sales force comprises the majority of the company, management wants to ensure complete redundancy at any expense. What solution would you suggest to management?

  1. A VPN 3030 Concentrator at the headquarters and VPN 3002 Hardware Clients for the sales force

  2. A VPN 3080 Concentrator at the headquarters and Cisco software clients for the sales force

  3. Two VPN 3080 Concentrators at the headquarters running VRRP and Cisco software clients for the sales force

  4. Two VPN 3030 Concentrators at the headquarters running VCA and Cisco software clients for the sales force

Answer C is correct. To ensure complete redundancy for the central headquarters, you should choose the VPN 3080 model because it ships standard with four SEP modules (two for redundancy) and two power supplies (one for redundancy). In addition, the fact that there will be two parallel VPN 3080 Concentrators running VRRP increases redundancy by providing SEP and power supply redundancy, as well as concentrator redundancy, in case one of the concentrators fails. Answers A and D suggests a 3030 Concentrator, which does not include SEP or power redundancy. Answer B uses the appropriate model, but a single concentrator failure will still cause downtime if it happens to fail.

Question 9

You have two VPN 3000 Concentrators running VRRP at the central location. When the master concentrator fails, which sessions need to be reconnected?

  1. Remote accesssessions need to be reconnected; however, LAN-to-LAN sessions are automatically saved.

  2. LAN-to-LAN sessions need to be reconnected; however, remote access sessions are automatically saved.

  3. Both LAN-to-LAN and remote access sessions are saved.

  4. Neither LAN-to-LAN or remote access sessions are saved.

Answer A is correct. When running two or more parallel concentrators with VRRP, if the master concentrator fails, only LAN-to-LAN sessions are automatically saved. Remote access sessions need to be reconnected by the clients; however, clients do not need to reconfigure their settings to reconnect. Answers B and D are incorrect because the LAN-to-LAN sessions do not need to be reconnected. Answer C is incorrect because remote access sessions need to be re-established by the clients.

Question 10

You have decided to utilize concentrator load balancing by using the Virtual Clustering Agent (VCA) protocol. You enabled the VCA protocol on the parallel concentrators, but users are always being connected to the master concentrator of the cluster. What is a possible cause for the load balancing to fail? (Choose two.)

  1. Load balancing requires all the concentrators to run VRRP.

  2. The concentrators in the cluster do not have the same virtual IP address configured for the VCA protocol.

  3. The concentrators do not have the VCA filters assigned to the public interface.

  4. The concentrators do not have the VCA filters assigned to the public and the private interfaces.

Answers B and D are correct. Concentrator load balancing requires that all the parallel concentrators have the same virtual IP address assigned. In addition, VCA protocols are not permitted to be sent or received on the interfaces unless you assign VCA filters to permit the protocol on the public and the private interfaces. Answer A is incorrect because the concentrator cannot load balance if running VRRP. Answer C is only partially correct. The filters must be present on all interfaces for the concentrators to send and receive VCA.

Question 11

Your managers have approached you complaining that their connections have been slow when using the VPN Concentrator at peak times. You are currently running version 3.5 on the VPN 3000 Concentrator. What two solutions can you implement to appease management? (Choose two.)

  1. Downgrade the software version because the 3.5 version has a known bug.

  2. Upgrade the software version to at least 3.6 to support bandwidth policies.

  3. Assign a traffic reservation policy to the manager's group.

  4. Assign a traffic policing policy to the manager's group.

Answers B and C are correct. Bandwidth management policies were introduced in software version 3.6. These policies enable you to either police bandwidth or reserve bandwidth during high utilization periods. Answer A is incorrect because there is not such a bug in the software version and the code should be updgraded rather than downgraded. Answer D does not reserve bandwidth for the managers. In fact, this actually limits the amount of bandwidth the managers receive.
