HOTSPOT
A network is choosing transceivers for switch-to-switch fiber links. Which factor affects the architect's choice?

정답:

A network architect is planning an HP Unified Wired-WLAN solution for an office. The wireless network must support:
What is one reason for using two HP 10500/7500 20G Unified Wired-WLAN modules as the controllers for this solution?

• A.The customer needs fast roaming, which requires a mobility solution between two Unified Wired-WLAN modules
• B.One module is required for traffic processing, and the other is required for key caching to enable roaming
• C.The Unified Wired-WLAN modules can be licensed and configured to provide redundancy for each other
• D.One module is required to control the APs, and the other is required for traffic processing

A customer has a virtualized data center. The virtual hosts use virtual distributed switches with multiple redundant uplinks, and these uplinks use Link Aggregation Control Protocol (LACP).
Which technology, available in HP switches, enhances high availability in this environment?

• A.Virtual Ethernet Port Aggregator (VEPA) combines redundant server links into a single high-bandwidth trunk
• B.NetStream and sFlow technologies provide the built-in capability to optimize bandwidth flows dynamically
• C.Fibre Channel over Ethernet (FCoE) allows the virtual hosts to send storage traffic over the server Ethernet uplinks if the FC connection fails
• D.Intelligent Resilient Framework (IRF) allows redundant server links to connect to different physical switches

Which technology, supported by HP FlexFabric solutions, can extend Layer 2 connectivity across a very large data center infrastructure?

• A.Shortest Path Bridging MAC-in-MAC mode (SPBM)
• B.Bi-directional Forwarding Detection (BFD)
• C.Edge Virtual Bridging (EVB)
• D.Multi-device connect (MDC)

A customer requires high availability, so the network architect is planning two area border (ABRs) for each non-backbone area in the Open Shortest Path First (OSPF) solution. What ensures a loop-free routing environment that meets the customer needs?

• A.All ABRs have at least one interface in area 0, and that interface has an IP address that is outside of the range of any summaries for area 0
• B.Only one ABR advertise a summary route for each area. For areas with multiple ABRs, each area can include two summaries ranges, and each ABR is configured with one of those ranges
• C.All ABRs in an area apply consistent path costs for their summary routes
• D.Each ABR in an area advertises the same summary routes for the area, and each ABR has a null route that matches those summaries
