A cloud service provider provisioned four active/active data centers in various locations within the country at 50 miles between each data center. The data centers must provide redundant network infrastructure and always be available to customers.

Which two data center design steps must be used to meet these requirements? (Choose two.)

A. Provide application hosting services to customers from the closest data center.

B. Implement active cluster in data centers 1 and 2 and backup in 3 and 4.

C. Use asynchronous replication between data centers 1 and 2.

D. Deploy database services in data center 1 and application layer to other data centers.

E. Configure application data replication to all backup data centers.

An engineer must connect an existing Cisco Fabric Interconnect to an IP-based storage array. The connection be a channel made directly between the fabric interconnect expansion module and the storage array. The engineer must also consider that the environment is running FCoE for storage and uses QoS to prioritize traffic. Which port type should be used to meet these requirements?

A. Network

B. Uplink

C. Appliance

D. server

Which two methods mitigate congestion in a SAN network? (Choose two.)

A. Configure ER_RDY to allow splitting of each ISL between switches into separate virtual links.

B. Use the port-monitor command to detect slow drain devices.

C. Configure the port channel to enable individual buffer-to-buffer credits.

D. Configure the port monitor to allow categorization of a specific device as slow.

E. Configure the flow control for the FC to use R_RDY.

A company runs mission-critical infrastructure in a single data center. Due to business growth It plans to open more data center in the coming years. A network engineer is asked to recommend a network technology for data center interconnection that allows scalability and seamless VM mobility while providing maximum security and fault isolation between data center. Which technology must be used to meet these requirements?

A. Cloudsec

B. UDLD

C. Trustsec

D. OTV

A customer needs a design for a new data center network that meets these requirements:

1.

Logically partition the environment into separate security domains.

2.

Cut costs related to purchasing additional equipment.

3.

Separate routing processes, TCAM, QoS tables, and data planes.

Which technology must be used?

A. VLAN

B. vPC

C. VDC

D. VRF

A Cisco engineer is developing a custom application that can run natively in Cisco NX-OS on Nexus 9000 and Nexus 3000 platforms For the NX-SDK application to run the engineer enables the NX-SDK feature on the device Then the NXSDK is imported into the application via an import nx_sdk_py statement. The engineer creates custom CLI commands and defines custom CLI command syntax within the sdkThread function

When CLI commands originate from an NX-SDK application what class is this?

A. clicm.printConsole

B. postCliCb

C. pyCmdhandler

D. nx_sdk_pyValid-to_int

Refer to the exhibit.

A Cisco engineer is configuring an active/active design that consists of Cisco Nexus 7000 Series Switches with Fabric Extenders using a vPC. The desired outcome is to allow the connection of servers/storage/devices to a single FEX, and use the FEX port channels to each parent switch to provide redundancy. The engineer configures FEX and FEX ID to be identical on both sides. During initial tests, an issue occurs with the straight-through FEX and active/active FEX configuration. What is the most probable reason?

A. They are not enabled on vPC+ deployments.

B. FEX-AA is not a supported F-Series module.

C. They cannot exist on the same ASIC instance.

D. Full duplex is disabled for FEX connectivity.

Refer to the exhibit.

An engineer is designing a new data center for a customer using Cisco proprietary technology. The engineer must ensure the highest availability and bandwidth for south-to-north traffic. Which design must the engineer choose to meet these criteria?

A. VPC between the two Nexus 5500 VPC+ between Nexus 5500 and Nexus 2K

B. VPC+ between the two Nexus 5500 Enhanced VPC between Nexus 5500 and Nexus 2K

C. VPC between the two Nexus 5500 and 7K Enhanced VPC between the two Nexus 5500

D. VPC+ between the two Nexus 5500 VPC between Nexus 5500 and Nexus 2K

An engineer must deploy a SAN that meets these criteria:

The upstream director switch must be configured to minimize the number of issued domain IDs

The access switch must aggregate multiple locally connected ports not a single uplink that shares the same domain ID as the upstream switch.

Drag and drop the port types from the right onto the boxes on the left to create a SAN topology that meets these requirements Not all port types are used Port types are used more than once.
