Data Center Flashcards

What is the primary function of Cisco Application Centric Infrastructure (ACI) in a data center?

Answer: Automate and manage network infrastructure

Cisco ACI is designed to automate and manage the network infrastructure within data centers, making it more efficient and scalable.

Which Cisco technology provides high-speed data center interconnect (DCI) solutions?

Answer: Cisco OTV (Overlay Transport Virtualization)

Cisco OTV is used for high-speed data center interconnect, enabling seamless connectivity between data centers.

In a Cisco UCS environment, what component is responsible for managing server profiles and configurations?

Answer: UCS Manager

UCS Manager is the component responsible for managing server profiles, configurations, and policies in a Cisco UCS environment.

Which protocol does Cisco ACI use for its policy enforcement mechanism?

Answer: VXLAN

Cisco ACI uses VXLAN (Virtual Extensible LAN) for its policy enforcement mechanism to provide scalable and flexible network segmentation.

What is the role of the Cisco Nexus 9000 series switches in a data center environment?

Answer: They are designed for high-performance, low-latency data center networks.

The Cisco Nexus 9000 series switches are optimized for high-performance, low-latency applications in data centers.

Which feature allows Cisco UCS servers to dynamically share storage resources across multiple servers?

Answer: Virtual Interface Card (VIC)

The Cisco UCS Virtual Interface Card (VIC) enables servers to dynamically share storage resources, providing flexible connectivity options.

In a Cisco ACI environment, what is an "endpoint group" (EPG)?

Answer: A logical grouping of endpoints with common policy requirements

An EPG is a logical grouping of endpoints (such as VMs, servers, or other devices) that share common network policies in Cisco ACI.

What is the main advantage of using Cisco Fabric Path in a data center?

Answer: Layer 2 multipath Ethernet fabric

Cisco Fabric Path provides a scalable, high-performance Layer 2 multipath Ethernet fabric for data center networks.

Which storage protocol is natively supported by Cisco MDS switches for SAN environments?

Answer: Fibre Channel

Cisco MDS switches natively support Fibre Channel, which is a key protocol used in Storage Area Networks (SANs).

In the context of Cisco UCS, what does "stateless computing" refer to?

Answer: The ability to manage server identities and configurations independently of physical hardware

Stateless computing in Cisco UCS allows server identities, configurations, and policies to be abstracted from the physical hardware, enabling flexibility and ease of management.

What is the main purpose of the Cisco Data Center Network Manager (DCNM)?

Answer: To monitor and manage data center network infrastructure

Cisco DCNM is used to monitor and manage data center network infrastructure, providing visibility and management capabilities for network operations.
