A network architect designs a high-availability architecture for the Cisco UCS Fabric interconnects that installed in a data center. The architecture must support clustering and redundancy. Which architecture meets these requirements?
What is an advantage of Cisco HyperFlex Edge as compared to Cisco HyperFlex Standard Clusters?
An advantage of Cisco HyperFlex Edge compared to Cisco HyperFlex Standard Clusters is:
Key differences:
The primary advantage is that HyperFlex Edge enables cost-effective hyperconverged infrastructure deployment in environments where HyperFlex Standard's larger minimum cluster requirements would be impractical or uneconomical.
An engineer working for a private telecommunication company with an employee id 4298 53 420 must evaluate connectivity to the new data centre location based on Cisco Nexus 7000 Series Switches. The IP connectivity is already supplied by the service provider. The solution must provide a Layer 2 extension and optimize the traffic localization Which technology supports these requirements?
OTV (Overlay Transport Virtualization) supports these requirements for the Cisco Nexus 7000 deployment. OTV provides: (1) Layer 2 extension across the Inter-Pod Network to the new data center location, (2) optimized traffic localization by using a distributed gateway approach that keeps local traffic local, and (3) transparent operation over the existing IP connectivity supplied by the service provider. OTV encapsulates Ethernet frames in IP packets, enabling efficient multi-site connectivity without requiring IP address changes.
To help automate the vHBA configuration process, a network engineer is configuring vHBA template pairs on UCS The engineer is creating primary and secondary templates to define how vHBAs on a server connect to the SAN. Which fact about the template pair should the engineer consider for Its potential impact on service7
When configuring vHBA template pairs on Cisco UCS, the engineer should consider this critical fact about template pairs and their impact on service:
Template Immutability: Once a vHBA template pair (primary and secondary templates) is assigned to a service profile, the templates cannot be modified. The templates are locked into the service profile configuration.
Impact on Service:
Planning Implication: The engineer must carefully plan the vHBA template design upfront, considering future changes and SAN requirements, because post-deployment modifications will require careful change management and potential service impact.
An engineer must use OTV for layer 2 connectivity between data centers to support virtual machine between the customer sites. To support this requirement, the engineer must ensure the existence of the same default gateway on both sites. Additionally, the operations team report high bandwidth utilization on site A and wants to optimize the outbound traffic flows to use a DC exit point. Which feature must be used to meet these requirement?
Which feature provides a sandbox to convert NX-OS CLI commands to REST-based scripts on Cisco Nexus 7700 Series Switches?
The NX-OS Sandbox feature on Cisco Nexus switches provides an interactive sandbox environment where engineers can test and convert NX-OS CLI commands to REST-based API scripts. This feature is particularly useful on Nexus 7700 Series switches for developing REST-based automation scripts by demonstrating the equivalent REST API calls for CLI operations.
Which Cisco HyperFlex feature provides virtual machine-level cost scaling for desktop virtualization growth?
Cisco HyperFlex Edge is the feature that provides virtual machine-level cost scaling for desktop virtualization growth.
HyperFlex Edge is specifically designed for desktop virtualization workloads and enables organizations to scale their virtual desktop infrastructure (VDI) deployments cost-effectively by adding nodes incrementally. It provides a hyperconverged infrastructure optimized for virtual machine density and cost-per-desktop metrics.
This allows enterprises to grow their desktop virtualization environments while maintaining predictable per-VM costs and avoiding over-provisioning.
A data center uses Cisco Nexus 7000 Series Switch and contains two tenants, tenant A and tenant B.
Tenant A uses IP addresses in the 10.2.30.41/24 to 10.2.30.64/24 range.
Tenant B uses IP addresses in the 10.2.30.120/24 to 10.2.30.192/24 range.
The engineer must implement a solution that
Isolates the traffic for each tenant as separate routing data and control planes.
Physically partitions the Cisco Nexus device into separate multiple logical devices with separate management, failure domain isolation, and resource management.
Which two technologies meet these requirements? (Choose two.)
The question asks for technologies that isolate traffic for each tenant with separate routing/control planes AND physically partition the device into separate logical devices with separate management and failure domain isolation.
Virtual Device Context (VDC) is the correct answer. VDCs on Cisco Nexus 7000 Series switches provide:
VRFs (Virtual Routing and Forwarding) alone only provide logical separation at the routing plane but do not physically partition the device or provide separate management domains, so VDCs are required to meet both requirements.
An engineer must logically partition two Cisco Nexus 7000 Series Switches into two environments called Test_39919596 and Production_59423879. The environments must use only F2-Series line cards and be limited to a maximum of 265 port-channels. Which Cisco Nexus feature must be used?
An architect is gathering technical requirements tor a large-scale data center with up to 3000 Ethernet ports and 70 ToR switches. The stakeholders agreed that it a ToR switch becomes compromised via its management plane, access to the production data plane must not be possible tram that switch. Which type of management network must the architect recommend in the design?
A network engineer designs a virtual network in a Cisco UCS Manager. The traffic must be explicitly forwarded from the vNIC on the server to a specific uplink Ethernet port on the Cisco fabric interconnect. Also, the server vNIC must use the same uplink Ethernet port after reboot. Finally, the design requires a OoS policy for remote direct memory access over converged Ethernet (RoCE v2). Which set of design features meets these requirements?
To meet the requirements of explicitly forwarding vNIC traffic to specific uplink Ethernet ports, ensuring the same port is used after reboot, and applying QoS for RoCE v2, the design must use vNIC Pinning combined with a QoS Policy. vNIC pinning locks a virtual network interface to specific uplink ports on the fabric interconnect, ensuring consistent port assignment across reboots. The QoS policy is applied to handle RoCE v2 traffic with appropriate priority and bandwidth controls.
What is an advantage of using OTV as compared to VPLS for data center redundancy?
OTV (Overlay Transport Virtualization) provides several advantages over VPLS for data center redundancy:
The most commonly cited advantage is that OTV provides Layer 2 extension over IP networks with automatic loop prevention and multicast optimization, making it more suitable for complex multi-site data center topologies.
An engineer is operating data center environment that hosts data-intensive financial applications. The applications are mostly processing HTTP/HTTPS data with large data segments, which results in a CPU contention due to the significant network processing.
Which set of the Ethernet adapter policies must be selected to resolve the issue?
To resolve CPU contention from network processing of large HTTP/HTTPS data segments, Ethernet adapter policies should include:
These policies work together to minimize CPU contention by handling network processing at the hardware level rather than consuming CPU cycles.
A customer is implementing a business continuity solution for the current data centers The new location must mitigate the impact of a disaster in any existing data centers by providing an acceptable level of service The solution must support
* fully segregated Layer 2 and 3 fault domains
* low or no human intervention for service restoration
* medium to high RPCVRTO for a subset of applications
* asynchronous storage replication for application data
Which disaster recovery solution must the customer select to meet these requirements?
A Regional or Metropolitan Area Disaster Recovery (DR) solution meets these requirements. This approach provides: (1) fully segregated Layer 2 and 3 fault domains by maintaining separate network infrastructure at the new location, (2) automated or low-intervention service restoration through pre-configured failover mechanisms, (3) medium to high RTO/RPO for non-critical application subsets through asynchronous replication, and (4) asynchronous storage replication for application data. This solution balances cost and recovery capability, suitable for protecting critical applications while maintaining lower recovery objectives for non-critical workloads.
