Why take this exam? Passing this exam (as long as you have the proper certification) qualifies you as an HP Accredited Systems Engineer Wireless Networks [2011], who: Can design and implement complex WLAN network solutions for large campus LAN environments using HP E-Series wireless technologies Has the foundational skills needed to implement A-Series wireless solutions Once you have the ASE Wireless Networks [2011] certification, you also have one component toward earning the ASE Network Infrastructure [2011] certification. To complete that certification, you only need to pass the Designing & Troubleshooting Open Standard Networks (HP0-Y32) exam. Who should take the exam? For this exam to count toward your ASE Wireless Networks [2011] certification, you must already have the ASE HP ProCurve Mobility 2009 or 2010 certification. If you do not have this certification, you must take the HP0-Y43 and HP0-Y33 exams. Refer to the study guides for those exams instead. In addition, most successful candidates have two years of real-world experience implementing and maintaining HP wired and wireless networks and have also prepared for the test in a variety of ways. This study guide describes some of these methods and indicates where you can obtain further preparation. How to study for the exam The Wireless Networks ASE 2011 Delta (HP0-Y35) exam tests you on topics that are covered in several HP instructor-led training (ILT) and Web-based training (WBT) courses (6 days total). Note that these courses train you in both wired and wireless technologies and products. While it is recommended that you complete this training, the training is neither required nor does it guarantee that you will pass the exam. It is expected that you will also study on your own and draw on your real-world experience. For example, you should be able to configure technologies such as multicast routing, OSPF, QoS, and security features on HP A-Series products. You must also demonstrate your ability to install HP A-Series APs, have the APs discovered by a controller, and set up basic wireless services using the controller. Read the sections below to further assess your options. Even if you do not intend to complete the recommended ILTs and WBTs, you should examine the topics that they cover because the exam will test you on your mastery of these topics. Attend recommended ILTs This ILT helps to prepare you for this exam: Implementing HP A-Series Networks, Rev 10.41 or later (5 days) You are highly encouraged to attend these courses, where you will expand your knowledge of wired and wireless technologies and gain hands-on experience implementing these technologies on HP A-Series equipment. Register for these courses in The Learning Center of your HP Partner Portal, which is the HP Learning Management System for HP customers and partners.

Rather than emphasizee simple memorization, HP exams attempt to assess whether you have the knowledge and skills that a networking professional requires on the job. Therefore, some questions feature exhibits or scenarios. As you see, you will have an average of just less than two minutes per question. Some questions will take much less time, and some will require a bit more. If allowed by the system, you might want to answer the questions about which you are sure first and then move back to the others. Before you do answer a question, take the time to read the question and all of the options carefully. If the question indicates that it features an exhibit, study the exhibit and reread the question. Make sure to select the answer that correctly responds to the question that is asked not simply an answer that includes some correct information. If the question asks for more than one answer, remember to select each correctt answer. You do not receive partial credit for a partially correct answer. Register To register for this exam, visit the HP ExpertOne exam page at: http://www.hp.com/certification/learn_more_about_exams.html You will need an HP Learner ID Sample questions Use these questions to help to assess whether you are ready to take the exam. An appendix at the end of this guide provides answers and explanations. 1. Your network is routing multicast messages using Protocol Independent Multicast-Sparse Mode (PIM-SM). A multicast source begins to a new stream. What message does the default router for the multicast source send? a. a Join message to the Bootstrap Router (BSR) b. a Join message to the Rendezvous Point (RP) c. a Register message to the Bootstrap Router (BSR) d. a Register message to the Rendezvous Point (RP) 2. The LAN shown in the exhibit is being designed as a single DiffServ domain. On which ports should packets be marked (or remarked) to comply with the DiffServ Model? (Select two.) a. inter-switch ports between the distribution layer switches b. the ports that connect the edge switches to the distribution switches c. the ports that connect the distribution ports to the edge switches d. clientt access ports e. serverr access ports 9
Figure 1: Exhibit for question 4 3. An HP A58000 switch enforces an ACL, which is shown in the configuration under the exhibit. You want to allow the client shown in the exhibit to access FTP services on the server. Which is true? a. You do not need to enter a command because the current configuration permits this traffic. b. You could permit the traffic with this command: permit tcp source 10.1.7.0 0.0.0.255 destination 10.1.4.12 0 destination-port range 20-21 c. You could permit the traffic with this command: permit tcp source 10.1.7.201 0 destination 10.1.4.12 0 destination-port range 20-21 d. You could permit the traffic with this command: rule 8 permit source 10.1.7.0 0.0.0.255 destination 10.1.4.12 0 destination-port range 20-21 e. You could permit the traffic with this command: rule 3 permit source 10.1.7.0 0 destination 10.1.4.12 0 destination-port range 20-21 Figure 2: Exhibit for question 4 A5800 ACL configuration [A5800] display acl 3003 Advanced ACL 3003, named lab, 6 rules ACL s step is 5 rule 0 permit tcp source 10.1.0.0 0.0.0.255 destination 10.1.4.12 0 destinationport range 20-21 rule 5 permit tcp source 10.1.7.0 0.0.0.255 destination 10.1.4.12 0 destinationport eq www rule 6 permit udp source 10.1.7.0 0.0.0.255 destination 10.1.4.12 0 destinationport eq dns rule 7 permit icmp source 10.1.7.0 0.0.0.255 destination 10.1.4.12 0 rule 10 deny ip source 10.1.0.0 0.0.255.255 destination 10.1.0.0 0.0.255.255.0 logging rule 15 permit ip 4. An endpoint that supports both IPv4 and IPv6 is connected to your HP A3610 switch. You want to assign to IPv4 traffic to VLAN 4 and the IPv6 traffic to VLAN 6. How do you do so? Conclusion a. Configure the endpoint s port as a hybrid port. Set VLAN 4 as the PVID and allow VLAN 6. b. Specify VLAN 6 as a protocol-based VLAN that selects IPv6. Configure the endpoint s port as a trunk port. Allow both VLAN 4 and 6, setting either VLAN as the PVID. c. Configure the endpoint s port as an access port set to VLAN 4. Then specifyvlan 6 as the port s IPv6 protocol-based VLAN setting. d.

HP wishes you success in the HP ExpertONE Program and in passing the exam for which you are preparing. 10
Appendix: Answers to sample questions This section provides answers and explanations for the sample questions. 1. Your network is routing multicast messages using Protocol Independent Multicast-Sparse Mode (PIMthet default router for the multicast SM). A multicast source begins to a new stream. What message does source send? a. a Join message to the Bootstrap Router (BSR) b. a Join message to the Rendezvous Point (RP) c. a Register message to the Bootstrap Router (BSR) d. a Register message to the Rendezvous Point (RP) Explanation: In PIM-SIM, a router sends a Join message to indicate that it needs to join the PIM-SM tree so that it can receive multicasts for hosts connected to it or to a downstream router. It is a Register message that indicates that the router is the first-hop router for a multicast source. Therefore, the correct answer must specify a Register message, and answers a and b are incorrect. The BSR is responsible for distributing RP-to-multicast address mappings. The RP is responsible for acting as the root of the tree for a particular multicast address, and Register messages are addressed to it. Therefore, answer d is correct. 2. The LAN shown in the exhibit is being designed as a single DiffServ domain. On which ports should packets be marked (or remarked) to comply with the DiffServ Model? Select two. a. inter-switch ports between the distribution layer switches b. the ports that connect the edge switches to the distribution switches c. the ports that connect the distribution ports to the edge switches d. clientt access ports e. serverr access ports Figure 1: Exhibit for question 4 Explanation: The DiffServ model specifies that you mark traffic (or remark already marked traffic) with a DSCP as close to the source as possible. For traffic destined to servers, the closest ports are the client access ports, so answer d is one correct answer. For return traffic from the servers to the clients, the closest ports as the server access ports, so answer e is another correctt answer. In a LAN that is a single DiffServ domain, the inter-switch ports should trust the DSCP marks placed by the client or server edge switches. However, they do not need to remark those values; therefore, answers a, b, and c are incorrect. 3. An HP A58000 switch enforces an ACL, which is shown in the configuration under the exhibit. You want to allow the client shown in the exhibit to access FTP services on the server. Which is true? 11
a. You do not need to enter a command because the current configuration permits this traffic. b. You could permit the traffic with this command: permit tcp source 10.1.7.0 0.0.0.255 destination 10.1.4.12 0 destination-port range 20-21 c. You could permit the traffic with this command: permit tcp source 10.1.7.201 0 destination 10.1..4.12 0 destination-port range 20-21 d. You could permit the traffic with this command: rule 8 permit source 10.1.7.0 0.0.0.255 destination 10.1.4.12 0 destination-port range 20-21 e. You could permit the traffic with this command: rule 3 permit source 10.1.7.0 0 destination 10.1..4.12 0 destination-port range 20-21 Explanation: First examine the ACL to determine whether it already permits the desired traffic: Rule 0 permits FTP traffic to the server (destination-port range 20 21); however, it only permits this traffic from sources in 10.1.0.0/24, and the client is in 10.1.7.0/24. Therefore, this rule does not permitt the desired traffic. Rule 5 deals with HTTP traffic (destination-port eq www). Therefore, it does not affect the traffic in question. Similarly, rules 6 and 7 relate to DNS and ICMP traffic and do not affect the traffic in question. Rule 10 denies all other IP traffic between endpoints in 10.1.0.0/ /16. This rule affects the traffic in question, which is between 10.1.7.201 and 10.1.4.12. Therefore, the ACL as it is will drop the desired traffic, and answer a is incorrect. Next, you must determine a valid command for altering the ACL to permit the desired traffic. You know thatt you must add the rule that permits the traffic before the rule that currently drops it in other words before rule 10. The commands in answers b and c add the new rule at the end of the list, so they are incorrect. The commands in both answers d and e add the rule in a valid order. However, the command in answer e does not select the correct traffic. Entering 0 for the wildcardd bits (source 10.1.7.0 0) forces an exact match with the listed IP address, which is not a valid IP address in this instance. You want to match the exact IP address, 10.1.7.201, or the entire 10.1.7.0/24 subnet. Answer d includes the correct wildcard bits for the second option (source 10.1.7.0 0.0.0.255). Answer d is correct. Figure 2: Exhibit for question 5 12
A5800 ACL configuration [A5800] display acl 3003 Advanced ACL 3003, named lab, 6 rules ACL s step is 5 rule 0 permit tcp source 10.1.0.0 0.0.0.255 destination 10.1.4.12 0 destinationport range 20-21 rule 5 permit tcp source 10.1.7.0 0.0.0.255 destination 10.1.4.12 0 destinationport eq www rule 6 permit udp source 10.1.7.0 0.0.0.255 destination 10.1.4.12 0 destinationport eq dns rule 7 permit icmp source 10.1.7.0 0.0.0.255 destination 10.1.4.12 0 rule 10 deny ip source 10.1.0.0 0.0.255.255 destination 10.1.0.0 0.0.255.255.0 logging rule 15 permit ip 4. An endpoint that supports both IPv4 and IPv6 is connected to your HP A3610 switch. You want to assign to IPv4 traffic to VLAN 4 and the IPv6 traffic to VLAN 6. How do you do so? a. Configure the endpoint s port as a hybrid port. Set VLAN 4 as the PVID and allow VLAN 6. b. Specify VLAN 6 as a protocol-based VLAN that selects IPv6. Configure the endpoint s port as a trunk port. Allow both VLAN 4 and 6, setting either VLAN as the PVID. c. Configure the endpoint s port as an access port set to VLAN 4. Then specify VLAN 6 as the port s IPv6 protocol-based VLAN setting. d. Specify VLAN 6 as a protocol-based VLAN that selects IPv6. Configure the endpoint s port as a hybrid port. Set VLAN 4 as the PVID and VLAN 6 as a protocol VLAN. Explanation: To assign IPv4 and IPv6 traffic received on the same port to different VLANs, you must complete several steps. You must create a protocol-based VLAN that specifies the correct VLAN ID and desired protocol. In addition, the port receiving the IPv4 and IPv6 traffic must be a hybrid port with the VLAN for IPv4 traffic as the PVID and the protocol-specific VLAN also specified. Answer a correctly includes specifying the port as a hybrid port, but it does not correctly describe how to create the protocol-based VLAN for IPv6 traffic. Answer b includes the correct method for creating the protocol-based VLAN, but it specifies the port as a trunk port, which is incorrect. Answer c is entirely incorrect, with the wrong type of port (access rather than hybrid) and an invalid way of specifying the settings for the protocol-based VLAN. Only answer d includes all of the correct steps. 13
