- Cisco Nexus 7000
- Cisco ASA Firewalls
- Cisco UCS (Unified Computing System)
Correct answer: Cisco OTV (Overlay Transport Virtualization)
Cisco OTV is used for high-speed data center interconnect, enabling seamless connectivity between data centers.
Question 3: In a Cisco UCS environment, what component is responsible for managing server profiles and configurations?
- UCS Manager (Correct answer)
- Fabric Interconnect
- Nexus Switch
- MDS Director
Correct answer: UCS Manager
UCS Manager is the component responsible for managing server profiles, configurations, and policies in a Cisco UCS environment.
Question 4: Which protocol does Cisco ACI use for its policy enforcement mechanism?
- EIGRP
- VXLAN (Correct answer)
- BGP
- OSPF
Correct answer: VXLAN
Cisco ACI uses VXLAN (Virtual Extensible LAN) for its policy enforcement mechanism to provide scalable and flexible network segmentation.
Question 5: What is the role of the Cisco Nexus 9000 series switches in a data center environment?
- They manage wireless network traffic.
- They are designed for high-performance, low-latency data center networks. (Correct answer)
- They are used for firewall security.
- They provide advanced routing capabilities.
Correct 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.
Question 6: Which feature allows Cisco UCS servers to dynamically share storage resources across multiple servers?
- Virtual Interface Card (VIC) (Correct answer)
- UCS Central
- SAN Fabric
- FCoE (Fibre Channel over Ethernet)
Correct answer: Virtual Interface Card (VIC)
The Cisco UCS Virtual Interface Card (VIC) enables servers to dynamically share storage resources, providing flexible connectivity options.
Question 7: In a Cisco ACI environment, what is an "endpoint group" (EPG)?
- A type of virtual machine
- A logical grouping of endpoints with common policy requirements (Correct answer)
- A set of physical servers
- A collection of network policies
Correct 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.
Question 8: What is the main advantage of using Cisco Fabric Path in a data center?
- Simplified VLAN management
- Layer 2 multipath Ethernet fabric (Correct answer)
- Enhanced wireless coverage
- Improved server cooling
Correct answer: Layer 2 multipath Ethernet fabric
Cisco Fabric Path provides a scalable, high-performance Layer 2 multipath Ethernet fabric for data center networks.
Question 9: Which storage protocol is natively supported by Cisco MDS switches for SAN environments?
- SMB
- Fibre Channel (Correct answer)
- NFS
- iSCSI
Correct answer: Fibre Channel
Cisco MDS switches natively support Fibre Channel, which is a key protocol used in Storage Area Networks (SANs).
Question 10: In the context of Cisco UCS, what does "stateless computing" refer to?
- The ability to manage server identities and configurations independently of physical hardware (Correct answer)
- Computing without the need for physical servers
- The use of cloud-based servers
- Running applications without a stateful firewall
Correct 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.
Question 11: What is the main purpose of the Cisco Data Center Network Manager (DCNM)?
- To monitor and manage data center network infrastructure (Correct answer)
- To manage wireless network access points
- To configure security policies
- To control access to cloud services
Correct 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.
