A network architect is proposing this solution to a customer. The customer network manager has a preference for Cisco VLAN Spanning Tree Plus (PVST+) because this protocol provides for fast convergence when a link fails and also provides per-VLAN load-sharing over links.
How would the network architect explain why the solution fits these requirements?
The MSTP component of the solution fulfills the same needs as PVST+ MSTP simply balances traffic per instance rather than per-VLAN
The redundant links between the switches are protected by MSTP and the built-in loop guard on HP-3800 switches. MSTP provides load-sharing and loop guard provides resiliency
The solution as shown provides the same load-sharing benefits as PVST+. To achieve the same resiliency benefits, the architect can add smart link to the meshed stack
The link aggregation between tiers provide even better resiliency and load-sharing than PVST+ while MSTP protects against accidental loops
Correct answer: D
Question 2
A network architect is explaining the differences between deploying two switches in an HP Intelligent Resiliency Framework (IRF) virtual switch and deploying two switches that implement standard Virtual Routing Redundancy Protocol (VRRP). Which statement correctly describes an advantage of IRF?
IRF failover occurs in 3 to 4 seconds, whereas VRPF failover occurs in 10 or more seconds
Unlike VRRP, which requires as least two addresses to be listed. Dynamic Host Configuration Protocol (DHCP) scopes list a single IP address for the default gateway
The IRF virtual switch runs a separate routing in each member, which enhances the redundancy and reliability of the overall solution
Multiple IRF members can actively route traffic for the same subnet and use the same IP address and routing control plane
Correct answer: D
Question 3
Which data center characteristics should specifically make the architect consider switches that support Shortest Path Bridging (SPB) or Transparent Interconnection of Lots of Links (TRILL)?
The customer requires redundancy and resiliency for the two data center routing switches
The customer requires high-speed routing between front-end servers and database servers in different subnets
The virtualized data center supports several thousand virtual machines (VMs) with a two-tier networking infrastructure topology
The data center requires many redundant links and must scale the tens of thousands of virtual (VMs)
