HP HP ASE HP0-Y50 Questions & Answers

• Question 21:

  After analyzing a hospital's applications, the network architect identifies two life-critical applications. What is the availability requirement for a life-critical application?

  A. 99%

  B. 99.9%

  C. 99.99%

  D. 99.999%

  Correct Answer: D

• Question 22:

  Refer to the exhibit.

  

  A network architect is proposing this solution to a customer. The customer network manager has a preference for Cisco VLAN Spanning Tree Plus (PVST+) because this protocol provides for fast convergence when a link fails and also provides per-VLAN load- sharing over links.

  How would the network architect explain why the solution fits these requirements?

  A. The MSTP component of the solution fulfills the same needs as PVST+ MSTP simply balances traffic per instance rather than per-VLAN

  B. The redundant links between the switches are protected by MSTP and the built-in loop guard on HP-3800 switches. MSTP provides load-sharing and loop guard provides resiliency

  C. The solution as shown provides the same load-sharing benefits as PVST+. To achieve the same resiliency benefits, the architect can add smart link to the meshed stack

  D. The link aggregation between tiers provide even better resiliency and load-sharing than PVST+ while MSTP protects against accidental loops

  Correct Answer: D

• Question 23:

  A network architect is designing a solution for a customer who wants better security on edge ports. Recently, an unauthorized individual was able to connect a snooping device to an open port (in other words, to a switch port that is active but not connected to a customer device). The customer wants to prevent this from happening again. However, the customer wants to avoid implementing 802.1X on ports because the IT staff is not prepared to deploy and manage such a solution.

  What is the simplest way to minimize the risk of another unauthorized connection without adding a lot of management overhead?

  A. Place open ports in a VLAN that is not carried on uplinks.

  B. Implement MAC lockdown (as opposed to MAC authentication) on all open ports.

  C. Apply MAC authentication to the open ports and allow only known MAC addresses

  D. Apply dynamic port access control lists (ACLs) to open ports.

  Correct Answer: A

• Question 24:

  Refer to the exhibit.

  

  All connections between switches are 10 Gbps. Switch is an Intelligent Resilient Framework (IRF) group with two member. Switch2 is an IRF group with two members.

  Switch1 and Switch2 route all traffic.

  A network architect is designing a solution for a finance company. One of the primary applications is a multicast application that delivers stock information to IP video screens across the site. The network architect is seeking a multicast

  solution that meets these needs:

  Simple configuration that the customer's IT staff can manage and troubleshoot No single point of failure for the multicast traffic What is the best solution for this environment and these needs?

  A. Protocol Independent Multicast (PIM) Dense Mode (DM).

  B. Protocol Independent Multicast (PIM) Sparse Mode (SM) with switch 1 and switch 2 configured as candidate Rendezvous Points (C-RPs), and switch1 and Switch2 also configured as Bootstrap Router (BSRs).

  C. Protocol Independent Multicast (PIM) Dense Mode (DM) with Switch1 and Switch2 set as the DM Master Router. Switch1 has a higher MR priority for an address associated with the multicast application.

  D. Protocol independent Multicast (PIM) Sparse Mode (SM) with switch1 and Switch2 set as the static Rendezvous Points (RPs). Switch1 has a higher RP priority for an address associated with the multicast application.

  Correct Answer: C

• Question 25:

  The exhibit shows the topology for a network with 30 access layer switches (only two are shown).Every switch-to-switch link is a Gigabit link. Every area network (VLAN) interface runs. Open Shortest Path First (OSPF) and has the IP address shown in the exhibit. The other interface settings are defaults.

  

  The access layer switches support several more VLANs not shown in the exhibit and also run Multiple Spanning Tree protocol (MSTP) loops. What is one recommendation for enhancing convergence time and resiliency for this solution?

  A. Place all of the switch-to-switch links in the same VLAN.

  B. Lower the cost of the VLAN interfaces to reflect the high speed of the links.

  C. Add a BPDU filter to the VLAN interfaces shown in the exhibit.

  D. Raise the OSPF times on the VLAN interfaces.

  Correct Answer: D

• Question 26:

  Refer to the exhibits.

  Exhibit 1

  

  Exhibit 2

  

  A customer has a existing solution, which is shown in Exhibit 1. (The solution actually includes more access layer switches than shown) in the existing solution, each access layer switch routes traffic.

  A network architect is proposing the HP FlexCampus solution shown in exhibit 2 in this proposed solution, the core intelligent Resilient Framework (IRF) virtual switch routes traffic, but the access layer switches do not.

  The customer likes that in the existing solution STP does not block either access layer uplink. The customer also likes that the existing solution does not require Virtual Router Redundancy Protocol (VRRP).

  What should the architect tell the customer about the benefits of the proposed solution?

  A. Although the IRF core must implement VRRP, STP does not block either access layer uplink, letting failover occur more quickly

  B. STP does not block either access layer uplink, and routing redundancy is provided without VRRP

  C. Although the IRF core must implement VRRP, VRRP is easier to set up than a dynamic routing protocol on all the switches

  D. STP will block one uplink on each access layer switch, but IRF enables failover to occur much more quickly

  Correct Answer: D

• Question 27:

  What is offered through the Network Strategy and Planning Services?

  A. Trouble shooting best practices

  B. Aligned strategy and initiative roadmap services

  C. Network Functions Virtualization Readiness Workshop

  D. Cloud Networking Return On Investment

  Correct Answer: B

• Question 28:

  An implementation plan should include an agreed-on time for the final rollback decision. What should this decision be scheduled?

  A. After the cutover to the new solution and the first set of validation tests and just before the user acceptance tests (UATs)

  B. after the first steps of the rollback plan have been implemented, about ten minutes before the end of the maintenance window

  C. just before the point of no return, which is calculated by subtracting the rollback time from the end of the maintenance window

  D. ten minutes before the end of the maintenance window or one hour into the implementation, whichever occur first

  Correct Answer: C

• Question 29:

  

  When does this design benefit a virtualized data center?

  A. The access layer and core switches use several layers of redundancy protocols, including Multiple Spanning Tree Protocol (MSTP) at Layer 2, Virtual Router Redundancy Procotol (VRRP) at Layer 3, and Intelligent Resilient Framework (IRF) at Layer 4.

  B. The access layer and core switches can connect on link aggregation groups. VLANs can extend across these aggregations, but they are more stable and highly-available than redundant Layer 2 links that use spanning tree.

  C. The access layer switches can integrate their Intelligent Resilient Framework (IRF) capabilities with those on the core switches to create a single CLOS fabric.

  D. The core switches can implement Virtual Ethernet Port Aggregator (VEPA) to extend tunnels for virtualized traffic across the data center backbone.

  Correct Answer: B
