4 Why take this exam? Passing this exam gives you one component toward HP Master Accredited Systems Engineer Network Infrastructure [2011] certification. This certification verifies that you can design, integrate, and support secure network solutions for large and complex enterprise networks using A-Series network technologies. NOTE Certain achievements might allow you to obtain this certification without taking this exam. See Who does not need to take this exam? HP Master ASE Network Infrastructure [2011] certification There are three paths to achieve this certification, as outlined below. The exams you must pass are dependent upon which achievements you currently hold. (Some form of previous certification is required; if you do not have any of the certifications listed in Table 1, obtain the HP ASE Network Infrastructure [2011] certification.) Path 1 This path is designed for networking professionals who have the HP ASE Network Infrastructure [2011] certification. In addition to taking the HP0-Y36 exam, you must pass the Migrating & Troubleshooting HP Enterprise Networks (HP0-Y37) exam. Path 2 This path is designed for networking professionals with both of these achievements: HP ASE Network Infrastructure [2011] HP Enterprise Networking Products Technical Qualification [2010] You only need to pass themigrating & Troubleshooting HP Enterprise Networks (HP0-Y37) exam. Path 3 This path is designed for networking professionals who have one of the following certifications. Master ASE HP ProCurve Campus LANs [2010] H3CSE CCIE Routing and Switching If you meet one of these criteria, you must pass the following exams: Designing & Troubleshooting Open Standard Networks (HP0-Y32) exam Migrating & Troubleshooting HP Enterprise Networks (HP0-Y37) exam By completing this path, you will also be granted the HP ASE Network Infrastructure [2011] certification. Table 1 summarizes these requirements. 4

Who should take the exam? Anyone can take the Deploying HP Enterprise Networks (HP0-Y36) exam, but most successful candidates have at least three to five years of real-world experience implementing and maintaining complex enterprise networks. Successful candidates also prepare for the test in a variety of ways. This guide describes some of these ways and provides references to materials for further preparation. NOTE Anyone can take the exam, but passing the exam only counts toward your HP Master ASE Network Infrastructure certification if you have the HP ASE Network Infrastructure [2011] certification as well. Candidates without any achievements should earn the HP ASE Network Infrastructure certification first. Candidates with other achievements should take different exams, as explained in Table 1 and the section below. Who does not need to take this exam? You do not need to take this exam if you have achieved any of the following certifications: Master ASE HP ProCurve Campus LANs [2010] H3CSE CCIE Routing and Switching With any of these achievements, you can obtain the HP Master ASE Network Infrastructure [2011] certification by passing these exams: Designing & Troubleshooting Open Standards Networks (HP0-Y32) Migrating & Troubleshooting HP Enterprise Networks (HP0-Y37) 5

6 In addition, if you have HP AIS Network Infrastructure [2011] certification plus the HP Enterprise Networking Products Technical Qualification [2010], you only need to take the HP0-Y37 exam. Refer to the Exam Prep Guides for these exams instead. How to study for the exam The Deploying HP Enterprise Networks (HP0-Y36) exam tests you on topics that are covered in the HP Enterprise Networks, Rev or later instructor-led training (ILT). This ILT is recommended for all candidates who need to take this exam. However, 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. The exam tests knowledge and skills necessary for an individual to be certified as an HP Master ASE, the highest level of certification. Therefore, the exam contains questions that are complex and demanding, reflecting the challenging nature of the tasks that the Master ASE often faces in complex, real-world network implementations. Read the sections below to further assess your options. You can register for this course in The Learning Center of your HP Partner Portal, which is the HP Learning Management System for HP customers and partners. You will require an HP Learner ID to register for a class. Note that, while it only takes a few minutes to request the ID, the process of activating it may take up to several days. Please obtain this ID and then register for classes at least one week in advance. Costs and scheduling vary according to region. Even if you do not intend to complete the recommended training, you should examine the topics that it covers because the exam will test you on your mastery of these topics. Attend the recommended ILT: HP Enterprise Networks Emphasizing hands-on lab activities and interactive classroom exercises, the HP Enterprise Networks training (Rev or later) focuses on the advanced switching and routing features required in enterprise-level networks. You will learn how to design, install, and maintain enterprise-level networks based on established core and backbone Layer 2 and Layer 3 technologies such as MPLS and Border Gateway Protocol 4 (BGP4). Topics covered After attending this course, you will be able to troubleshoot all of the following: High-end HP A-Series switches and routers Enterprise routing features BGPv4 Enterprise multicast features MPLS L2 and L3 MPLS virtual private networks (VPNs) Virtual Private LAN Service (VPLS) Format offered 4-day instructor-led course with 35% lecture, 15% participant-centered learning, and 50% hands-on labs More information If you are interested, the course datasheet discusses HP Enterprise Networks in more detail. It is available at Purchase self-study materials Rather than attend the ILT, you can prepare for HP certification exams at your convenience, with HP-approved Official Exam Certification Guides. Learn at your own pace, with self-study guides written by industry experts. Each guide takes you through complex subjects with detailed, step-by-step explanations, diagrams, chapter quizzes and a practice exam. Remember that simply reading the self-study materials will not give you the hands-on experience provided by labs in the ILT. Both the study guide and exam assumes that you have real-world experience implementing complex enterprise networks. To purchase the self-study materials associated with this exam, visit 6

7 Take the official HP practice exam Another option to prepare for this exam is to take the official HP practice exam. While this guide provides a few sample questions, the official HP practice exam contains a full bank of questions that cover all of the test objectives of the real certification exam. To maximize value, explanations for the right and wrong answers are provided, which will help you evaluate your readiness to pass the certification exam. Keep in mind, however, that while the practice exam is very thorough, passing it does not guarantee that you will pass the certification exam. To take the practice exams, you need to go to the ExpertOne exam page and log on with a user ID. Mobile versions are available in the itunes store and will be in Android marketplaces at a later date. Details can be found at: Details are also available on the HP networking training site: Obtain hands-on experience All HP exams are designed for networking professionals with on-the-job experience, but the Master ASE-level exams in particular require extensive experience. Even if you attend the recommended ILT, you should also have a great deal of experience working with HP A-Series products on the job. The exam will call on you to demonstrate experience with topics that are not specifically included in the recommended training. These include: Advanced OSPF and RIP routing Advanced multicast routing Advanced security topics Advanced Layer 2 and Layer 3 Quality of Service (QoS) How to take the Deploying HP Enterprise Networks (HP0-Y36) exam Table 2 provides details about the exam.

9 Comments on the exam During the exam, participants can make specific comments about the items (i.e. accuracy, appropriateness to audience, etc). HP welcomes these comments as part of our continuous improvement process. Special tips for this exam This exam focuses on HP A-Series products. Some questions might not specifically state that a switch or router is an HP A-Series product. Nonetheless, unless otherwise stated, you should answer the question according to the functionality on HP A-Series products. Some questions will require you to know how A-Series products implement technologies at factory default settings. Tips for taking HP exams Rather than emphasize 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 over two-and-a-half minutes per question. Some questions might take 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 correct answer. You do not receive partial credit for a partially correct answer.

A multicast source for is active on Hosts in subnets /24 and /24 are able to receive the multicasts. However, hosts in subnet /24, connected to Router 3, are not. You determine that Router 3 can ping Router 1 at its loopback address, , which is the RP for PIM-SM, the protocol that this network is using for multicast routing. You also know that all routers are OSPF neighbors. Figure 2: Exhibit for question 2 10

11 You enter the display pim routing-table command on Router 3 and see that there are no entries for You enter several other commands and diagnose this issue as a problem with Router 3 failing to accept the hosts requests to receive the multicasts. Which command or commands allowed you to diagnose this problem? a. <Router-3> display igmp group <Router-3> display igmp interfaces b. <Router-3> display pim interface <Router-3> display pim rp-info c. <Router-3> display multicast-boundary d. <Router-3> display pim rp-info <Router-3> display pim bsr-info 3. You have been asked to configure OSPF on an HP A-Series router to accomplish the following: Enable OSPF and assign the router ID Place all current interfaces and future interfaces in area 0 Enable bidirectional forwarding detection (BFD) on all interfaces Which set of commands accomplishes these tasks? a. ospf 1 router-id area 0 network bfd interface vlan-interface <ID> b. ospf 1 router-id area 0 network interface vlan-interface <ID> ospf bfd enable c. ospf 1 router-id area 0 network bfd interface vlan-interface <ID> d. ospf 1 router-id area 0 network interface vlan-interface <ID> ospf bfd enable 11

14 Appendix: Sample question answers This section provides answers and explanations for the sample questions. 1. A service provider offers several types of MPLS VPNs to its customers. Provider edge router PE-2 connects directly to three customers, as shown in the exhibit, and provides these services: Customer MPLS service Number of sites A MPLS Kompala mode 5 B MPLS Martini 3 C Martini VPLS 2 How many remote Label Distribution Protocol (LDP) peering relationships does PE2 have at minimum? a. 1 b. 2 c. 3 d. 4 e. 5 f. 6 g. 7 Explanation: PE-2 must establish remote LDP peering relationships for VPNs that use LDP for the outer tunnel. Both MPLS Martini and Martini VPLS VPNs use LDP, but MPLS Kompala does not. Therefore, you consider only Customer B and Customer C sites. PE-2 must establish a remote LDP relationship to each router that connects to a Customer A site or a Customer B site. It can use the same relationship to tunnel traffic for multiple customers. If you examine the figure, you see three peers that support either Customer B sites, Customer C sites, or both. Therefore, PE2 must establish three remote LDP relationships (answer c). Figure 1: Exhibit for question 1 2. In the network shown in the exhibit, Router 1 is the hub of a star topology. Routers 2, 3, and 4 are spokes and not interconnected. A multicast source for is active on Hosts in subnets /24 and /24 are able to receive the multicasts. However, hosts in subnet /24, connected to Router 3, are not. You determine that Router 3 can ping Router 1 at its loopback address, , which is the RP for PIM-SM, the protocol that this network is using for multicast routing. You also know that all routers are OSPF neighbors. 14

15 Figure 2: Exhibit for question 2 You enter the display pim routing-table command and see that there are no entries for You enter several other commands and diagnose this issue as a problem with Router 3 failing to accept hosts requests to receive the multicasts. Which command or commands allowed you to diagnose this problem? a. <Router-3> display igmp group <Router-3> display igmp interfaces b. <Router-3> display pim interface <Router-3> display pim rp-info c. <Router-3> display multicast-boundary d. <Router-3> display pim rp-info <Router-3> display pim bsr-info Explanation: Because the display pim routing-table command did not display either a *, G entry nor an S,G entry, you know that Router 3 has not even joined the RP tree, let alone received multicasts. This problem could occur for several reasons, but the question indicates that, in this instance, the router is not accepting requests from hosts to join the group. Hosts use Internet Group Management Protocol (IGMP) to indicate that they want to receive multicasts for a particular group. The commands in answer a correctly diagnose this problem. The display igmp group command indicates whether Router 3 has joined the multicast group. If you see that it has not, but you know that hosts have tried to join the group, you know that the router is not accepting the joins for some reason. You should check whether IGMP is enabled on the interface with display igmp interfaces. The commands in answer b diagnose different problems. The first command lets you see whether PIM is enabled on the interface that connects to the RP, and the second command indicates whether Router 3 knows an RP for the multicast group in question. Both commands could help you to troubleshoot the original problem described in the question. However, they do not help with the diagnosis indicated in the answer, so this answer is not correct. The display multicast-boundary command in answer c does not troubleshoot the problem described in the question. This command indicates multicast boundaries that might prevent Router 3 from forwarding or receiving multicasts on a particular interface. However, it does not indicate why the Router has not received the hosts requests nor even joined the multicast group. Finally, the commands in answer d diagnose different causes of the problem than the one indicated in the question. These commands would let you diagnose a problem with Router 3 receiving the correct information about the RP for the multicast group. 15

16 3. You have been asked to configure OSPF on an HP A-Series router to accomplish the following: Enable OSPF and assign the router ID Place all current interfaces and future interfaces in area 0 Enable bidirectional forwarding detection (BFD) on all interfaces Which set of commands accomplishes these tasks? a. ospf 1 router-id area 0 network bfd interface vlan-interface <ID> b. ospf 1 router-id area 0 network interface vlan-interface <ID> ospf bfd enable c. ospf 1 router-id area 0 network bfd interface vlan-interface <ID> d. ospf 1 router-id area 0 network interface vlan-interface <ID> ospf bfd enable Explanation: To answer this question, you must understand how to use the network command to enable OSPF on a network on an A-Series router. You must also know the proper CLI location for enabling BFD. In the OSPF network command, you specify first the network address and then the wildcard bits. In the wildcard bits, a 1 indicates that that bit in the network address is ignored. Therefore, the wildcard bits must be to select all network addresses, which will enable OSPF on all current and future interfaces as indicated in the question. Both answers a and b include the correct network command. Answers c and d do not, so you know that they are incorrect. The correct location for enabling BFD is the interface view not the OSPF view. Of answers a and b, answer b indicates the correct location. Therefore, answer b is correct. 4. The exhibit displays the topology for a network that implements BGP. Router 4 in AS 20 advertises prefix /8, and Router 5 in AS 30 advertises prefix /8. Figure 3: Exhibit for question 4 16

17 Refer to the command outputs and the partial configurations below. On Router-3, what is the Next Hop attribute for prefix /8? a b c d e f Explanation: To answer this question, consider the Next Hop attribute as prefix /8 is advertised to Router-2, then to Router-1 (the route reflector), and finally to Router-3. Router-2 receives the prefix from an ebgp peer. The Next Hop attribute is the peer s IP address on the advertising interface, Router-2 then advertises the prefix to Router-1, an ibgp peer. Typically, when a router advertises a prefix received from an ebgp peer to an ibgp peer, it does not change the Next Hop attribute. However, the configuration shows that Router-2 enables the next-hop-local option for Router-1. With this option, Router-2 does specify its own IP address as the Next Hop attribute. Therefore, it advertises the address with the Next Hop attribute, Router-1 also has the next-hop-local option for Router-3; however, Router-1 is forwarding the route as a route reflector. When forwarding a route reflected from another route reflector client, the route reflector does not change the Next Hop attribute even when the next-hop-local option is specified for the peer. Therefore, the Next Hop attribute remains , answer d. Router-1 BGP peers <Router-1>display bgp peer BGP local router ID : Local AS number : 9925 Total number of peers : 2 Peers in established state : 2 Peer AS MsgRcvd MsgSent OutQ PrefRcv Up/Down State :22:39 Established :43:44 Established Router-1 BGP configuration bgp 9925 undo synchronization peer as-number 9925 peer reflect-client peer next-hop-local peer as-number 9925 peer reflect-client peer next-hop-local Router-2 BGP configuration bgp 9925 undo synchronization peer as-number 9925 peer next-hop-local peer as-number 20 Router-3 BGP configuration bgp 9925 undo synchronization peer as-number 9925 peer next-hop-local peer as-number 30 17

18 5. All routers shown in the exhibit are configured for OSPF and MPLS on all interfaces. Router P-3 and Router P-5 have two directly-connected LDP peers. Traffic from Router PE-1 destined for IP address is label-swapped from P-3 to P-4. Label-Switching Router (LSR) P-3 allocates MPLS label 11 for FEC /32 and label 12 for FEC /32. LSR P-4 allocates MPLS label 21 for FEC /32 and MPLS label 22 for FEC /32. Router PE-2 pings sourced from interface Loopback 0. Which MPLS label is on this packet on the link between P-4 and P-3? a. 11 b. 12 c. 21 d. 22 Explanation: When an LSR label-swaps a packet over a link, it inserts the label that the next hop assigns to the FEC. In this question, the packet s FEC is P-3 allocates label 11 for this FEC, so P-4 inserts this label. Answer a is correct.
