HP HP ASE HP0-Y50 Questions & Answers

• Question 11:

  What correctly describes one trend that is changing how network architects must design the data center network infrastructure?

  A. Applications are drawing on more and more locally stored data, which causes customers to favor blade servers and blade enclosures

  B. Applications are considering on single, highly available mainframes, driving the need for 10G connections to the server edge

  C. Applications are increasingly virtualized, which requires architects to implement routing at the access layer to segment each rack into its own VLAN

  D. Applications are scaling out across multiple servers, increasing communications between servers distributed across the data center

  Correct Answer: D

• Question 12:

  

  A company has several branch offers, each of which has four VLANs: one for employees, one for guests, one for network infrastructure local services. At each office, a VLAN has a maximum of 200 endpoints. Each branch office represents one Open Shortest path First (OSP) architect has created the plan shown in the exhibit for IP addressing. What is a potential disadvantage of this design?

  A. The subnets are large enough to accommodate fewer endpoints. But not large enough to accommodate 200 end points

  B. It makes it more complicated for the company to add subnets to branches in the future.

  C. The scheme uses private network addressing space, which is not permitted for use with OSPF.

  D. The address blocks do not provide enough IP addresses for the devices currently at each branch.

  Correct Answer: B

• Question 13:

  Refer to the exhibit.

  

  The network architect is planning network addresses for the VLANs shown. The company is using the private 10.0.0.0/8 space. Which guidelines should the network architect follow?

  A. Use a/22 subnet for each VLAN to ensure enough IP addresses for each large modular switch

  B. Implement the port isolation feature and apply several /30 subnets to each VLAN

  C. Use a/25 subnet for each VLAN to conserve the limited IP addressing space

  D. Use a /24 subnet for each VLAN for simplicity and scalability

  Correct Answer: D

• Question 14:

  A network is planning the products that interconnect a main site campus LAN, branches, and data center (located at a different site from campus). Which customer requirement would causes the network architect to choose HP enterprise-class modular routers as opposed as deep-buffer switches for this solution?

  A. The need for WAN connections that use T3/E3/J3

  B. The need or a fully redundant solution with two devices working as a team

  C. The need for thousand of routes in the routing table

  D. The need for high-speed routing

  Correct Answer: A

• Question 15:

  A data center has a traditional three-tier network design with routing at the distribution layer. The customer is virtualizing its servers and adding technologies such as live migration of virtual machines (VMs). How well does the architecture (topology) meet the needs of the customer's changing environment?

  A. This topology is not ideal in supporting the low-latency Layer 2 communications that this environment requires

  B. This topology is ideal because it enforces consolidation of virtualized server domains

  C. This topology is not ideal because it enforces consolidation of virtualized server domains

  D. This topology is not ideal for supporting the Secure Virtualization Framework (SVF) required to protect the virtual servers

  Correct Answer: A

• Question 16:

  Refer to the exhibit.

  

  The customer requirements include resilience for branch communications. If anyone link fails, a branch can still reach the main office servers. In addition either one of the 5920 switches at the core of the WAN should be able to fail with branches still maintaining their connections.

  What should the network architect include in the design to meet this requirement?

  A. A connection directly to an ISP to each branch router, which also requires the OSPF area to become a not so stubby area (NSSA)

  B. Virtual Router Redundancy Protocol (VRRP) enabled and configured in the switches in the 5920 IRF group

  C. Graceful restart on the 5920 IRF group in standard IETF mode

  D. A floating static route on the branch switches to the 5920 IRF group in case the OSPF solution fails

  Correct Answer: A

• Question 17:

  A customer wants a simple solution for deploying virtual services at a branch. Which devices support modules running a VMware ESXi hypervisor? (Select two)

  A. HP 2920 Switch Series

  B. HP MSR30 Router Series

  C. HP 5400 zl Switch Series

  D. HP 7500 Switch Series

  E. HP VSR1000 Virtual Services Routers

  Correct Answer: BE

• Question 18:

  Refer to the exhibit.

  

  The exhibit shows how two NICs on a physical server connect to two HP 5820 switches. The server supports eight virtual machines (VMs) with VMware version 5.1. The VMware standard virtual switch is bound to NIC and NIC2. This switch implements source MAC load balancing for the NIC team.

  What is the proper configuration for ports 1/0/1 and 2/0/1?

  A. Place the ports in a bridge aggregation group that does not use LACP

  B. Place the ports in a bridge aggregation group that uses LACP

  C. Enable LACP on the individual ports

  D. Do not place the ports in a bridge aggregation group

  Correct Answer: B

• Question 19:

  Refer to the exhibit.

  

  A network architect has designed the topology shown in the exhibit. The Gigabit links between distribution layer and the core uses OM3 grade multi-mode fiber between 100m and 150m long.

  The solution is for an enterprise customer whose employees use mostly HTTP-based applications and have medium utilization needs.

  What should the network architect do to resolve a potential issue?

  A. Add more bandwidth between each pair of distribution layer switches

  B. Add more links between each modular switch at the access layer and its distribution layer switch

  C. Replace the modular switches at the access layer with switches that support stacked meshing

  D. Remove the distribution layer since it is not needed in this environment

  Correct Answer: C

• Question 20:

  A customer prefers fixed-port switches at the campus access layer. The network architect wants to propose access layer switches simplifying network architecture and network management.

  Which technologies should the network architect consider? (Select two.)

  A. Multiple Protocol Label Switching (MPLS)

  B. Virtual Routing and Forwarding (VRF)

  C. Intelligent Resilient Framework (IRF)

  D. Backplane stacking

  E. Net Stream

  Correct Answer: CD
