Tips for taking this exam

Rather than emphasize simple memorization, HP exams attempt to assess whether or not you have the knowledge and skills that a networking professional requires on the job. Therefore, many questions featureexhibits or scenarios. As you see, you will have an average of two minutes and thirty seconds per question.Some questions will take less time, and some will require more. Before you answer a question, take the time to read the question and all of the options carefully. If the question indicates that it features one or more exhibits, study the exhibits and reread the question.


This exam validates that you can successfully perform the following:

Solution Planning and Design

  • Assess customer needs, including the customer’s goals, current environment, and issues.
    o Assess a company’s purpose for implementing a wireless network and determine the specific requirements for using it.
  • Create designs which meet customer requirements and needs, which have been qualified in the planning state.
    o Determine the requirements for radio frequency (RF) coverage and capacity and plan the wireless cells to meet those requirements.
    o Design and implement a solution for wireless guest access that features HP MSM products and a centralized NOC.
    o Plan how to distribute users’ traffic onto the wired network based on customer requirements.


Solution Implementation

  • Configure devices.
    o Set up subscription services on an MSM Controller.
    o Configure an external RADIUS server to authenticate guests and apply appropriate access controls.
    o Enable the MSM Controller to work with an external Web server to provide secure, customized access for guests.
    o Ensure that MTM interacts correctly with RADIUS-based VLAN assignments.
    o Configure MTM on a single controller to distribute traffic according to plan.
    o Configure MTM on multiple controllers in a mobility domain to distribute traffic according to plan.
  • Implement required security devices (such as RF Manager).
    o Describe HP RF Manager Controller’s role in securing a wireless network.
    o Plan the deployment of sensors.
    o Install HP RF Manager and complete the initial setup.
    o Use RF Manager to locate and quarantine rogue APs.
    o Set up intrusion prevention with RF Manager to enforce a company’s security policy.
  • Validate wireless coverage, roaming, and capacity results compared to design using tools and best practices.


Solution Optimization

  • Optimize small- to medium-sized wireless network infrastructures for SMB and commercial customers.
  • Optimize large, complex, multi-site unified wired/wireless networks for corporate customers.
  • Assess sensitive traffic and determine appropriate tools for optimizing traffic flow (using QoS).
    o Determine which traffic requires priority handling and which QoS mechanisms clients support.
    o Determine which values are available for QoS settings, based on the particular QoS protocol in use.
    o Plan QoS to ensure that time-sensitive traffic receives priority handling through the entire pathway between a wireless device and the destination device.
  • Optimize and scale wireless network designs (coverage area, site survey, RF planning, RF optimization).
    o Plan, prepare, and conduct a site survey.


Solution Troubleshooting

  • Troubleshoot small- to medium-sized wireless network infrastructures for SMB and commercial customers.
    o Determine the cause of issues with wireless performance.
    o Find sources of interference and either remove them or redesign RF coverage to avoid them.
    o Manage hidden nodes, clients that fail to roam properly, legacy clients, and other special situations.
    o Identify why 802.1X authentication to an external RADIUS server fails and resolve the problem.
    o Isolate and resolve issues with guest authentication to an external Web page, an external RADIUS server, or both.
    o Determine how to resolve the issue when users cannot receive IP addresses.
  • Troubleshoot small- to medium-sized networks, including WAN/wireless connections to remote sites.
  • Utilize specific tools appropriate for troubleshooting wireless networks and mobility infrastructures.
    o Use information collected by HP MSM products, as well as third-party tools, to analyze signal and interference.


Solution Management

  • Review and take action on alerts and log files (mitigation steps, scripted responses, escalation, and so on).
