You are evaluating Cisco UCS for use in a data center. Which two options describe benefits of using Cisco UCS as compared to traditional blade-server systems? (Choose two.)

• A.Cisco UCS reduces the number of required management interfaces.
• B.Cisco UCS offers hardware iSCSI server adapters for storage connectivity.
• C.Cisco UCS reduces the deployment time of new blade servers.
• D.The power consumption of Cisco UCS is no more than 5 KWh per 42RU rack.
• E.Cisco UCS offers a built-in storage array of SSD disks for higher performance.
• F.Cisco UCS offers 100-Gbps interfaces on each blade server.

Which option is an example of the network services that are provided at the aggregation layer of the data center network?

• A.ACE
• B.LISP
• C.MPLS
• D.OTV

The ANSI restriction that only 239 Fibre Channel domains are allowed per SAN fabric creates challenges for the designer working on a Cisco Data Center Unified Fabric network.
Which two approaches can the designer utilize to restrict the number of Fibre Channel domains below 239? (Choose two.)

• A.Daisy chain up to 100 core Fibre Channel switches, leaving 139 domains for the network edge.
• B.Assign a domain ID for each blade switch and top-of-rack access layer switch.
• C.Use NPV to cause a fabric or blade switch to appear as a host to the core Fibre Channel switch.
• D.Migrate to FCoE to eliminate the need for Fibre Channel domains.
• E.Utilize VSANs to allow scaling well beyond 239 domain IDs.

Which technology can you implement to improve inbound path optimization to data centers?

• A.LISP
• B.FabricPath
• C.MPLS VPN over mGRE
• D.OTV

Which option is a characteristic of the data center aggregation layer?

• A.segments groups of applications and isolates problems
• B.is a high-speed backbone of the data center
• C.offers QoS services, such as the classification and marking of traffic
• D.provides access for IP multicast applications
