A customer is beginning to implement IPv6 in conjunction with IPv4 in its private network. The customer has obtained this IPv6 Block: 2003:DBB:1:1000::/52. The network architect is planning IPv6 addresses for these subnets:
-VLAN 10 with100 users -VLAN 20 with 130 users The customer wants to use stateless autoconfiguration to assign IP address to the endpoints.
How should the network architect plan the IPv6 subnet address for each VLANs?

• A.The subnet for each VLAN should use a /104 subnet address, such as 2003:DB8:1:1000::100:0/104
• B.The subnet for each VLAN should use a /112 subnet address, such as 2003:DB8:1:0/112.
• C.The subnet for each VLANs should use a /56 subnet address, such as 2003:DB8:1:1100::/56
• D.The subnet for each VLAN should use a /64 subnet address, such as 2003:DB8:1:1001::/64

A hospital CIO tells the network architect that the current network solution is not performing well.
The hospital has access layer that supports 48 10/100/1000 Mbps ports and one Gigabit uplink. The hospital is seeking an upgrade to provide better performance and redundancy. The CIO cannot provide the 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 network.
The CIO does indicate that these applications are important:
-Voice over IP(VoIP) -Scheduling and buildingapplications -Patient data logging -Medical imaging
The network architect needs to plan appropriate oversubscription ration 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.Which 802.1p value the VoIP applications use to mark their traffic
• C.Whether the billing applications and patient data require encryption.
• D.Whether the VoIP traffic must be forwarded at Layer 2 or whether it can be routed.

Which customer requirement is mostly likely to cause the network architect to search for an HP alliance solution?

• A.Network management solution for a multi-vendor environment
• B.An infrastructure Detection System/Infrastructure Prevention System (IDS/IPS) for virtualized environment.
• C.High-capacity, Border Gateway Protocol (BGP)-capable router
• D.Load balancing appliances for a data center solution

A network architect is planning a solution for a customer who has voice over IP (VoIP) phones with Ethernet connections and also voice over WLAN (VoWLAN) phones that use 802.1g connections:
-The VoIPphones and VoIPserver use standard 802.1pvalue 5 and DillServ Code Point(DSCP)46 to mark voicetraffic. -The VoWLAN phones use WiFi Multimedia(WMM)to send their traffic at high priority.
What should the network architect do to ensure that voice traffic on its way to a VoWAN phone is given the correct priority?

• A.Make sure that the switches convert the 802.1p values to VMM values.
• B.Make sure that the APs support 802.1n even if they also support backward compatibility with 802.11b/g.
• C.Make sure that the VoWLAN phones support 802.1X and VLAN tagging.
• D.Make sure that the MSM Controller has a DSCP map assigns DSCP 46 to the highest WMM category.

Refer to the exhibit.

The branch switches and the HP intelligent Resilient Framework (IRF) group shows in the exhibit implement Open Shortest Path First (OSPF). The IRF group acts as the area border (ABR), enabling OSPF on network as follows:
-In area 0,OSPF is enabled on network 10.0.0.0/16 -In area 2, OSPF is enabled on network 10.2.0.0/16
The ABR also has these area summary ranges:
-For area 0,10.0.0.0/16 -For area 2, 10.2.0.0/16
Which task should the network architect on the IRF group to follow best practices for router IDs?

• A.Change the range for the area 0 summary to 10.0.0.0/8 so that it includes the router ID of
  10.255.0.2
• B.Change the loopback IP address to 10.0.255.2 because the router ID must always fall within the area summary
• C.Add 10.255.0.2/32 to one of the OSPF areas so that the address is advertised and the router ID is pingable
• D.Rename the loopback interface and, instead, use the router ID command to set the router ID manually
