HOTSPOT
A network architect is choosing transceivers for switches-to-switches fiber links. Which factors affect the architect's choice?
Hot Area:
The exhibit shows the topology for an enterprise customer LAN with an on-site data center. The Intelligent Resilient Framework (IRF) group switches supports a group of computers that very high availability to the data center. Therefore the customer has requested a backup that extends directly between the IRF group and the data center core. All of the VLAN interfaces and routed link aggregations that are shown implement Open Shortest Path First (OSPF) in a single area.
Which tasks should the network architect complete to ensure that the HP 5500 IRF group selects the correct path to the data center during (Select two).
A. Change the reference bandwidth to 80000 on all routing devices.
B. Configure the VLAN 101 interfaces as silent interfaces.
C. Change the reference bandwidth on the VLAN 101 interfaces to 1000.
D. Set the cost on the VLAN 100 interfaces to 2Set the cost for the VLAN 101 interfaces to 80.
E. Change the reference bandwidth on the VLAN 100 interfaces to 20000.
Refer to the exhibit.
The exhibit shows a network with HP 3500 yl Series switches at the access layer and HP 8206 zl switches at the core. The customer with this solution has logged several support calls, which were eventually tracked down to spanning tree issues. How can a network architect adjust the solution to prevent the issue in the failure?
A. Implement BPDU filters on the switch-to-switch links and loop protection edge ports
B. Connect three or four 3500 y1 switches together in a group. Establish a distributed trunk between two switches in each group and the core switches
C. Implement BPDU guard and broadcast suppression on all the switch-to-switch links
D. Configure distributed Trunking on the two 8200 zl switches at the core. Create a distributed trunk between the core switches and each 3500 yl switch
Which description best characterizes current trends in deploying services for an enterprise?
A. Companies are connecting multiple sites together but distributing services to each site to increase resiliency and responsiveness.
B. Companies are moving services out of the private cloud into more responsive pods that are distributed throughout the campus LAN.
C. Companies are transforming their campus LAN and data centers into one large Layer 2 network
D. Companies are centralizing services in a consolidated data center or even a highly scalable private cloud
Which benefit does In-Service Software Upgrades (ISSU) provide?
A. Schedules and performs switch upgrades through HP Intelligent Management Center (IMC)
B. Upgrades members of an IRF virtual switch one at a time to avoid services disruption
C. Upgrades members of theIRF virtual switch simultaneously to ensure all members use the same software version
D. Automatically checks for software updates on the HP Websites, downloads the new software, and upgrades the switches
An architect is planning an HP Wired-WLAN solution for a customer with Voice over WLAN (VoWLAN) devices, which support 5 GHz and 2.4 GHz, and the laptops. What is a potential advantage of dual-radio 802.1n APs for this environment?
A. They can load balance a single phone's traffic between the two radios
B. The can use 802.1n band steering to shift only the laptops to the 2.4 Ghz radio
C. They can support a single VLAN for phones and laptops, but use load balancing to move all phones to one radio
D. They can support a voice WLAN on one RADIO and an employee WLAN on the other radio
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
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
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
Refer to the exhibit.
The exhibit is a plan for Open Shortest Path First (OSPF) areas. What should the network architect do to improve the OSPF network design?
A. Add a redundant link in area 0 between each branch router and the data center core Intelligent Resilient Framework (IRF)
B. Change area 1 and area 2 to not so stubby areas (NSSAs) or normal areas
C. Move the boundary between area 1 and area 0 to Router 1 make the same change to area 2
D. Implement routing on the 5930 switches. Make Switch 10 an area border router (ABR) between area 0 and a new area
