- A. Authentication solution
- B. Data security solution

Answer : D
Refer to the exhibit.
A customer has the solution in the exhibit, which includes more access layer switches than are shown. Members of the customer network team mention they are considering access layer routing for a new solution to eliminate Spanning Tree Protocol (STP) and Virtual
Router Redundancy protocol (VRRP). However they are concerned about meaning the routing solution. The network architect proposes a solution that eliminates STP and VRRP without requiring routing at the access layer, although the solution can use access layer routing.
Which solution fits that description?
- A. Two HP 10500 Series, using intelligent Resilient Framework (IRF) at the core, HP S400 zl Series switches at the access layer
- B. Two HP 10500 Series switches, using Hot Standby Router Protocol (HSRP), at the core. HP 2600 Series switch at the access layer
- C. Two HP 8200 zl Series switches, using distributed Trunking, at the core. HP 5400 zl Series switches at the access layer
- D. Two HP zl Series switches, using backplane stacking, at the core. HP 5400 zl Series switches, using the backbone stacking at the access layer
Answer : B
Refer to the exhibit.
A network architect is designing the logical topology for a campus LAN networking solution.
The customer requires support for 2400 edge ports, which is provided by 10 intelligent
Resilient Framework (IRF) groups at the access layer. This customer does not have a wireless network nor anticipants adding one in the next two years. However, the customer does want to authenticate users with 802.1X and use the network RADIUS server to divide users from different groups into different VLANs. The customer has three user groups, each of which includes between 600 and 900 users.
Additionally, the customer understands that the RADIUS server will require several policies but wants to keep these policies as simple and easy to maintain as possible.
How can the network architect ensure that the solution meets the customer needs and also follows best practice?
- A. Assign a /23 subnet to each VLAN so that the VLAN can accommodate the required number of users, even if users connect multiple devices
- B. Plan a different VLAN ID and subnet address for each user group on each access layer IRF group. Either core or access layer routing will work for this solution
- C. Use access layer routing. Assign a different subnet to VLAN2 on one access layer IRF group then the VLAN2 on the another access layer group
- D. Plan a solution for designing dissolvable agents to the endpoints so that they can complete 802.1X authentication seamlessly
Answer : B
A network architect is planning a backplane stack with four HP 3800 switches. Which topology provides the highest level of redundancy?
- A. Star
- B. Mesh
- C. Chain
- D. Ring
Answer : B
A hospital CIO tells the network architect that the current network solution is not performing well. The hospital has access layer switches that support 4810/100/1000 Mbps ports and one Gigabit uplink. The hospital is seeking an upgrade to provide better performance and redundancy.
The CIO cannot provide network architect more detailed information about traffic patterns and utilization but does not want the network architect to install intelligent Management
Center (IMC) and analyze the traffic.
-> The CIO does indicate that these applications are important:
-> Voice over IP (VoIP)
-> Scheduling and billing application
-> Patient data logging
-> Medical imaging
The network architect needs to plan an appropriate oversubscription ratio for access layer uplinks.
What is one piece of information that the architect should collect for this task?
- A. How much bandwidth the medical imaging applications require
- B. Whether the VoIP traffic must be forwarded at layer 2 or whether it can be routed
- C. Whether the billing applications and patient data require encryption
- D. Which 802.1p value the VoIP applications use to mark their traffic
Answer : A
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+)
Answer : C
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.

Endpoint Discovery (LLDP-MED). The phase need to receive their VLAN ID using this protocol. The network architect is proposing HP 5500-48G-PoE+EI switches. Each user computer connects to the phone, which then connects to the Ethernet jack. LLDP is enabled on the switch. Each Edge port is trunk port that permits VLAN 10 (the user VLAN) and VLAN 20 (the voice VLAN).
Which other setting recommended on the edge port?
- A. The voice VLAN is enabled
- B. The PVID is set to VLAN 20
- C. LLDP Cisco Discovery Protocol (CDP) compliance enabled
- D. The LLDP voice VLAN ID is set to 20
