A. About 5 seconds

B. About 5 minutes

C. About 50 minutes

D. About 5 hours

A customer is seeking an upgrade for their campus LAN network. Currently, the customer has access layer switches that support 18.10/100/1000 Mbps ports and one Gigabit uplink. The customer wants better performance in the upgrade but also wants to minimize costs.

The network architect has used the Network Traffic Analyzer (NTA) for Intelligent Management Center (IMC) to collect information about the access layer uplinks. These are the results:

For switches on Floor1, the peak utilization is 650 Mbps on a Gigabit uplink. On most days, the utilization peaks at about 400 Mbps. Peaks usually occur briefly. For switches on Floo2, the peak utilization is 800 Mbps on a Gigabit Uplink.

During active periods, the utilization often remain near 800.

What is most appropriate plan for oversubscription in the new access layer? (For this question, think only about oversubscription and not customer needs for redundancy)

A. 48 1 on floor 1 and 24 1 on floor 2

B. 24.1 on floor 1 and 4.1 on floor 2

C. 48 1 in all locations

D. 24 1 in all locations

A network architect has designed a two-tier topology for the campus LAN and is planning to implement routing at the core. Which requirement might cause the network architect to consider implementing routing at the access layer?

A. Employees in different VLANs need to use collaboration applications to share high- resolution graphic files

B. The solution must support an isolated VLAN for wired guest devices

C. Employees need to be placed in dynamic VLANs, assigned by a RADIUS server in identity, so that network managers can manage the solution more easily

D. The customer has an HP Unified Wired-WLAN solution, and wireless users need to roam seamlessly across the site

Data center includes services within the same VLAN and subnet that communicate with each other multicast application. Variable Internet Group Management Protocol (IGMP) on this VLAN on data center switches?

A. To enforce security boundaries between servers assigned to different multicast groups

B. To eliminate multicast traffic on server ports that have not requested the multicasts

C. To ensure that different applications do not use overlapping multicasts addresses

D. To enable the servers to hear each other's multicast transmission

Which exhibit shows the better Open Shortest Path First (OSPF) area scheme and for which reason?

A. Exhibit 1 because it allows the application of access control lists (ACLs) between users and the data center

B. Exhibit 1 because the campus and data are separate areas

C. Exhibit 2 because every area has similar numbers of routers

D. Exhibit 1 because every area has fewer than 50 routers

E. Exhibit 2 because every area has fewer than 35 routers

Which task does the HP Software-Defined Networking (SDN) Developer Support Description service help a customer perform?

A. Replace existing virtual switches with HP-supported software-based switches.

B. Create, test, and troubleshoot SDN applications

C. Determine whether the company's network infrastructure is ready for SDN.

D. Develop a migration plan to an SDN environment.

A network architect is working with a customer to implement a new network design. The network architect has learned that the company has a legacy application hosted on a number of legacy servers. The legacy application must remain intact and after the new network implementation. As the company plans to continue using it indefinitely.

With which stakeholder should the network architect discuss the technical detail of the legacy system and any challenges or specifics about maintaining interoperability?

A. Chief Executive officer (CEO)

B. Network Architect or Planning Engineer

C. Chief Information Officer (CIO) or Voice President (VP)/ Director of IT

D. Chief Financial Officer (CFO) or Voice President (VP)/ Director of Finance

A network architect has collected data on link utilization. When analyzing link utilization, what is the general guideline?

A. You upgrade a link that is often used at more than 50 percent utilization

B. You upgrade a link when it reaches 100 percent utilization

C. You upgrade a link if it sometimes peaks at more than 50 percent utilization

D. You upgrade a link when it reaches 25 to 30 percent utilization

Refer to the exhibit.

The branch routers have E1 lines into the Frame Relay Service provider network. The exhibit shows just one branch, but the network actually has 30 branches. The HP 6600 Series routers, which are the area border routers (ABRs), have E2

lines into the Frame Relay network.

The routers in the exhibit Open Shortest Path First (OSPF). The enable OSPF on network follows:

In area 2, OSPF is enabled on network 10.2.0.0/16 In area 0, OSPF is enabled on network 10.0.0.0/16

The customer requires resilience at the WAN core. Which design change best supports that requirement?

A. Add additional links from the HP 6600 Series routers to the WAN

B. On each branch router, add a floating static route to one of the ABRs in case the OSPF solution fails

C. Add a Gigabit link between the HP 6600 Series router with a network in area 0 and area 2.

D. At each branch, add a redundant link between the switch and the router

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

A network architect is planning a complete access layer and core upgrade for customer's campus LAN. The campus has four large buildings, each requiring between 1000 and 3000 edge ports. Which factor will play a primary role in determining whether the network architect needs to plan a two-tier or three-tier topology for the campus LAN?

A. The number of fiber links between each building and the building where the core switches reside

B. Whether the customer requires a wireless solution

C. The high number of edge ports that the solution requires

D. Whether the customer can afford core switches that support intelligent Resilient Framework (IRF)
