The customer also wants to centralize management and traffic distribution as much as possible. What should the architect suggest? A customer has a virtualized data center that uses Microsoft Hyper-V Windows Server 2012. The customer has provided this information about the hosts for the VMs: Each host has a network (Hyper-V virtual switch) that supports VM production traffic and own 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 In 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 connection to each host? A network architect is designing a solution with HP products. A customer has the following requirements for controlling the management access for administrators: Administrators are assigned privileges when they log in based on their identity Security policies related to password complexity and password rotation, like the company's Windows domain policies, are enforced for administrator credentials The company can easily revoke the access of administrator how have the company method Administrator have a backdoor into the management interface in case network connectivity fails in any way Which option meets the company's requirements? 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 network architect is choosing fabric module for an HP 10500 Series Switch. Which factors affect the choice? A network architect is choosing core switches for an enterprise data center. One potential model has CLOS hardware architecture, and the other model has a cross-bar architecture.
