Cisco Implementing Cisco Data Center Unified Fabric (DCUFI) Set 1

1.

Which statement about Cisco FabricPath is true?

It is the best solution for interconnecting multiple data centers. It optimizes STP throughout the Layer 2 network. It is a simplified extension of Layer 3 networks across a single data center. The Cisco FabricPath domain appears as a single STP bridge, where each edge port uses the same MAC address.

2.

Which statement about scalability in Cisco OTV is true?

The control plane avoids flooding by exchanging MAC reachability. IP-based functionality provides Layer 3 extension over any transport. Any encapsulation overhead is avoided by using IS-IS. Unknown unicasts are handled by the authoritative edge device.

3.

Which Cisco Nexus feature is best managed with DCNM-SAN?

VSS domain parameters virtual switches AAA

4.

Which of the following Cisco Nexus features is best managed with DCNM-LAN?

VSS Domain parameters Virtual switches AAA

5.

Which statement about electronic programmable logic device image upgrades is true?

EPLD and ISSU image upgrades are nondisruptive. An EPLD upgrade must be performed during an ISSU system or kickstart upgrade. Whether the module being upgraded is online or offline, only the EPLD images that have different current and new versions are upgraded. You can execute an upgrade or downgrade only from the active supervisor module.

6.

Customer has configured fabhcpath allocate-delay to 600. What is the effect of this?

The allocate-delay is the time for FPto go into forwarding state It specifies the time delay for a transitioned value to be propagated throughout the network It specifies the time delay for a link bringup to detect conflicts The allocate-delay is the time delay for a new resource to be propagated throughout the network

7.

Which statement explains why a Cisco UCS 6200 Fabric Interconnect that is configured in end- host mode is beneficial to the unified fabric network?

There is support for multiple (power of 2) uplinks. Upstream Layer 2 disjoint networks will remain separated. The 6200 can connect directly via vPC to a Layer 3 aggregation device. STP is not required on the uplink ports from the 6200.

8.

Which option is a restriction of the unified ports on the Cisco UCS 6200 Series Fabric Interconnect when connecting to the unified fabric network?

Direct FC connections are not supported to Cisco MDS switches The FCoE or Fibre Channel port allocations must be contiguous on the 6200. 10-G Fibre Channel ports only use SFP+ interfaces. vPC is not supported on the Ethernet ports.

9.

Which statement about the implementation of Cisco TrustSec on Cisco Nexus 7000 Series Switches is true?

While SGACL enforcement and SGT propagation are supported on the M and F modules, 802.1AE (MACsec) support is available only on the M module. SGT Exchange Protocol is required to propagate the SGTs across F modules that lack hardware support for Cisco TrustSec. AAA authentication and authorization is supported using TACACS or RADIUS to a Cisco Secure Access Control Server. Both Cisco TrustSec and 802.1X can be configured on an F or M module interface.

10.

What is an Overlay Transport Virtualization extended VLAN?

the VLAN used to locate other AEDs the VLAN used to access the overlay network by the join interface the user VLAN that exists in multiple sites the VLAN that must contain the overlay interface
