QUESTION 121
A large financial institution hosts all customer data in a critical data center with a single physical location. Top management is concerned about the risk of a single-site failure, but budget is also an issue, so the network engineering team is working to implement a cost-effective redundancy strategy with a second data center. The new data center must use a three-tier design identical to the existing data center. Business requirements dictate that all data must always be accessible from anywhere in the world, even if a single site fails. The team purchased two Cisco Nexus 7700 Series Switches and four Catalyst 8000 Series Routers. Which action must the team take to accomplish the goal?

A. Implement OTV with the Nexus 7700 Series devices to extend Layer 2 connectivity between the two data centers and provide disaster-recovery capabilities.
B. Implement NVGRE on the Catalyst 8000 routers to create a DCI communication channel between the data centers and provide Layer 2 extension capabilities.
C. Implement HSRP with the Nexus 7700 Series devices to provide gateway redundancy to ensure seamless failover between the Nexus switches.
D. Implement FabricPath on the Catalyst 8000 routers in both data centers to provide full redundancy in the event of a disaster.

Correct Answer: A

QUESTION 124
A Cisco engineer is analyzing a customer environment where dozens of VMs are running on a physical server and UCS chassis are cascaded. The setup uses two ISLs in a port channel to the SAN switch (per fabric). The oversubscription from VM to physical SAN port is often 20 (VMs/host) x 72 (9 UCS chassis cascaded = 72 hosts): 2 (ISLs from fabric interconnect to SAN switch port on the NPV core (NPIV enabled switch). This results to 20 x 72:2 per single ISL = 720 VMs per ISL. 20 (VMs per host) x 8 (hosts per chassis) x 9 (chassis per port channel to SAN switch) / 2 (ISLs per port channel) = 20 x 8 x 9 / 2 = 720 VMs per SAN F-port. What is the best way to resolve possible IOPS bottleneck?

A. Configure 802.1Qbb priority flow control.
B. Deploy a content dellvery network.
C. Remove data encryption on the SSD.
D. Enable Windows 1Gb server full duplex.

Correct Answer: A

A. ECMP routes on the IP network to facilitate load sharing
B. trunk configuration toward the iSCSI SAN device for multiple VLANs

QUESTION 127
A Cisco engineer is discussing a data center design scenario that consists of 24 Cisco UCS B200M6 blade servers, 2 Cisco UCS 6454 Fabric Interconnects, and 3 Cisco UCS 5108 server chassis. In the proposed configuration, the server links, which are NICs on the blades, are associated with a single uplink port. Server-to-server Layer 2 traffic is locally switched, server-to-network traffic goes out on its pinned uplink port, and each server MAC address must be learned before traffic can be forwarded to it. Which feature stipulates that traffic is forwarded to a server only if it is received on a pinned uplink port for this server?

A. host F_Port channeling
B. RPF check
C. native VLAN tagging on both sides
D. MAC address table virtualization

Correct Answer: C
