A customer in Europe needs to establish an 11-Mbps wireless bridge link between two office buildings that are approximately 1.3 km apart. The wireless link will pass through a public park, which contains a lake that is surrounded by trees. You run the range calculation and determine that the Cisco Aironet 1300 Series Outdoor Access Point/Bridge should work. You install the link using 10.5-dB yagis with 75 feet of standard Cisco cabling and both radios set at 20 mW. The wireless bridges are not able to establish or maintain a link. What is needed to successfully complete this link?
The antenna must be raised high enough to clear the trees.
The customer wants to implement wireless security through implementation of WPAv2. Which component of WPAv2 would limit the rollout because of the continued use of old access points?
AES
In what location is it recommended that the Cisco Catalyst 6500 Series WLSM be placed?
distribution layer
In a new Cisco UC520 installation, when must IP routing be configured?
When the service provider assigns static IP information.
Which of the following best describe the customer benefits of change management in the operate phase? verifying that the system meets operational, functional, and interface requirements
improve the return on investment and hasten migration by identifying and planning for necessary infrastructure changes and resource additions, as well as reduce deployment costs by analyzing gaps early in the planning process to determine what is needed to support the system
You connect via Telnet to a Cisco access point and enter the command show dot11 linktest. Which output might you obtain?
incoming and outgoing signal strength
What port role assignment would you make for the Gigabit Ethernet port on the Cisco CE520 used in the Smart Business Communications System?
Cisco UC520
Which definition best describes the implementation service component within the implement phase?
installing, configuring, and integrating systems components based on an implementation plan developed in earlier phases
Which dial plan scenario may require PSTN trunks for outbound calls?
All the employees, the auto attendant or receptionist, and the voice-mail system have direct inward dial numbers using analog trunks.
How can the proper configuration of Voice Mail be tested at an end user's IP phone?
Press the "Messages" button.
Which two benefits will a client see from adding a Wireless LAN Controller to their Smart Business Communications System? (Choose two.)
allow for guest access
add additional access points
What two types of telephony interfaces are used for PSTN connectivity? (Choose two.)
Digital
Analog
You have configured and applied a Cisco IOS Firewall access rule to the inbound, untrusted interface. You suspect that the rule may be blocking necessary traffic onto the network. What must you do to delete that rule when using Cisco Router and Security Device Manager?
You must remove the association between the rule and the interface before deleting the rule.
Which design phase service component includes the development and documentation of the test case or cases used to verify that a deployed infrastructure meets operational, functional, and interface requirements?
Systems Acceptance Test Plan Development
A North American customer is using 2.4-GHz radios in a point-to-point configuration. The radio power level is 17 dBm and is transmitting at 11 Mbps. The customer is using 21.5-dBi dish antennas and 50 feet of cabling, with a loss of 8.4 dB per 100 feet. The customer increased the distance between the transmitter stations and began experiencing link problems. Without using a professional installer, which step should the customer take to fix the situation?
Use a cable with lower loss.
Which statement correctly describes configuration of the VPN server?
It uses a preshared key for remote device authentication.
In which of these phases is a customer's network assessed to determine its system readiness?
plan
Which statement correctly describes the keyswitch model of deployment for call processing?
All IP Phones are able to answer any incoming PSTN call on any line.
You are troubleshooting OSPF neighbor establishment problems, which are occurring over Frame Relay interfaces that use the default OSPF network type. What should you verify in the router configuration?
the frame-relay map statement on the Frame Relay interface
Which critical issue should you account for when implementing an integrated network security management design?
all network devices are time-synchronized
Which benefit can be obtained by using the change management service component in the operate phase?
reduced operating costs, due to a consistent framework for making necessary changes in an efficient and accountable manner
A customer with a small enterprise network of 15 remote sites is trying to optimize its VPN by migrating some remote sites using Frame Relay connections to the Internet to using cable connections to the Internet. Minimizing costs is one of the customer's highest priorities. Only a moderate amount of IP traffic is passing through the network, most of which is from the remote sites to the central site. IPSec should be used to provide VPN functionality and basic confidentiality is desired. Based on the traffic patterns, which topology would be the easiest for this customer to set up and manage?
hub-and-spoke
A company needs to provide site-to-site VPN, remote access VPN, and firewall protection. Which device best supports all three functions?
Cisco ASA
You have just configured and enabled the Cisco IOS Firewall feature set from a remote location using the Cisco Router and Security Device Manager (SDM) Firewall wizard. You later want to double-check your configuration using Cisco SDM. However, you find that you can no longer connect to the Cisco IOS Firewall using Cisco SDM. What is the probable cause of this failure?
You have been locked out via access lists that have been applied to the router as a result of your Cisco SDM configuration.
Which of these is the best definition of the Cisco Lifecycle Services approach?
It defines the minimum set of services required to successfully deploy and operate a set of Cisco technologies.
