• Question 51:

  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.

  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.
  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.

  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

• Question 55:

  HOTSPOT

  

  The network architect is designing an Open Shortest Path First (OSPF) solution and plans to run OSPF on each of the VLAN in switches. Based on the practices, which interface or interfaces should the network architect plan the features on?

  Hot Area:

  

  

• Question 56:

  Customer has a virtualized data center Microsoft Hyper-V Windows Server 2012. The customer has provided this information about the Ms:

  Each host has a network (Hyper-V virtual switch) that supports VM productions traffic and owns two server 10G NICs.

  Each host has a network (Hyper-V virtual switch) that supports management traffic to the parent partition and owns two server Gigabit NICs. Each rack, the network architect plans to deploy two HP 5920 Series switches, acting as an

  Intelligent Resilient Framework (IRF) switch.

  Which additional information does the architect need in order to plan the connections to each host?

  A. Whether the virtual switches use sFlow or Net Stream to load balance traffic over the NICs
  B. Whether the virtual switches use Virtual Ethernet Port Aggregator (VEPA) VLAN tagging
  C. Whether the virtual switches use generic or dynamic NIC teaming (Link Aggregation Control [(LACP)] and their hashing method
  D. Whether the virtual switches support standard Spanning Tree Protocol (STP) or Cisco Per-VLAN Spanning Tree Protocol Plus (PVST+)
  C. Whether the virtual switches use generic or dynamic NIC teaming (Link Aggregation Control [(LACP)] and their hashing method

• Question 57:

  Refer to the exhibit.

  

  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 virtual local area network (VLAN) interface runs Open Shortest Path First (OSPF) and has

  the IP address shows in the exhibit. The interface settings are at the defaults.

  The access layer switches support more VLANs not shown in the exhibit and also run Multiple Spanning Tree Protocol (MSTP) as a protection against loops.

  What is one recommendation for enhancing convergence time and resiliency for this solution?

  A. Add a BPDU filter to the VLAN interfaces shown in the exhibit
  B. Lower the cost of the VLAN interfaces to reflect the high speed of the links
  C. Place all the switch-to-switch links in the same VLAN
  D. Raise the OSPF timers on the VLAN interfaces
  A. Add a BPDU filter to the VLAN interfaces shown in the exhibit

• Question 58:

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

• Question 59:

  A company is upgrading a data center network solution in phases. The first phase involves updating the top of rack (ToR) switches in one rack. Other switches will be updated in their phases. What is one benefit of this approach?

  A. It allows the through testing of the solution in real-world circumstances
  B. It ensures that the network can be updated without any scheduled downtime
  C. It removes the need to conduct connectivity and failover tests during the implementation
  D. It removes the need for working with customer change management processes
  C. It removes the need to conduct connectivity and failover tests during the implementation

• Question 60:

  A network architect is planning a guest solution for a group of ports in a conference room. Guests should have access to the Internet only. The company wants a simple solution and prefers not to burden visitors with login requests. Which solution would best meet the company's requirements for a gust network?

  A. Place the ports in a black-hole VLAN that is not carried on Switch-to-Switch links. Apply a dynamic VLAN for guests who pass web authentication to a server that allows MAC registration
  B. Place the guest ports that is allowed access only to the internet. Optionally configure port isolation.
  C. Apply MAC lockdown to the guest ports. Configure switches to place unknown MAC addresses in a VLAN with access only to the internet
  D. Apply web authentication to the guest ports. Use the built-in guest accounts for HP switches to authenticate the users
  A. Place the ports in a black-hole VLAN that is not carried on Switch-to-Switch links. Apply a dynamic VLAN for guests who pass web authentication to a server that allows MAC registration
