A network engineer must select a high availability feature for their data center. The solution must ensure network resilience, reduce network instability for Layer 3 routing protocols, and meet these requirements:
1.
The device must notify its neighbors when the control plane is undergoing a restart.
2.
The solution must suppress routing flaps in case of stateful switchovers. Which solution must be implemented?
A. BFD
B. HSRP
C. NSF
D. ISSU
A network administrator must create a redundant vHBA for the mission-critical virtual machines (VMs) installed on a Cisco UCS Fabric Interconnect blade server. The VMs access multiple datastores using VSAN55 and VSAN95. The datastore on which the VMs are hosted must be accessible if any of the uplinks goes offline.
Which action meets these requirements?
A. Attach VSAN55 to vHBA1 and VSAN95 to vHBA2.
B. Assign VSAN55 and VSAN95 to vHBA1 and vHBA2.
C. Enable failover for the vHBA with VSAN55 and VSAN95 enabled.
D. Configure load-balancing for vHBAs with VSAN55 and VSAN95 attached.
What are two advantages of using Cisco vPC as compared to traditional access layer designs? (Choose two.)
A. supports Layer 3 port channels
B. disables spanning-tree
C. no spanning-tree blocked ports
D. uses all available uplink bandwidth
E. maintains single control plane
Which two configuration methods can be used to deploy QoS to Cisco MDS Series switches? (Choose two.)
A. zone-based QoS
B. multiple QoS policies that match individual devices
C. VSAN-based QoS
D. FCoE VLAN-based QoS
E. multiple QoS policies that match multiple devices
An engineer is building a data center network with VXLAN EVPN. The requirement is to use multicast for the broadcast, unknown unicast, and multicast replication.
Which two VNI to multicast group mapping methods must be used to meet these requirements? (Choose two.)
A. many NVE to one multicast group
B. one VNI to one multicast group
C. many VNI to one multicast group
D. one NVE to many multicast groups
E. many VNI to many multicast groups
An engineer is implementing a Cisco UCS environment The requirements for the solution are for the MAC addresses to be learned only on the server-facing ports. The use of the Spanning Tree Protocol must be avoided. Also, the engineer must have deterministic traffic handling from blades to uplink ports.
Which two settings must be selected to meet these requirements? (Choose two.)
A. end-host mode
B. dynamic pinning
C. NPIV mode
D. static pinning
E. switching mode
After experiencing traffic disruptions from the failure of a single router, a customer asks an engineer to design a solution that will prevent this from occurring in the future. While examining the customer's environment, the engineer discovers that the routers are manufactured by a variety of different vendors, and they have varying amounts of CPU and memory resources. Additionally, several of the customer's applications require the ability to fine-tune the load-balancing parameters between multiple routers.
Which solution should be used to meet these requirements?
A. VRRP
B. GLBP
C. FHRP
D. HSRP
An engineer finishes the initial set up of a VXLAN EVPN network. The engineer is asked to plan for connectivity that supports redundancy and extends multiple virtual routing and forwarding domains. The requirement is to use the same default gateway addressing across all leaf switches that belong to the VXLAN network.
Which two solution must be used to meet these requirements? (Choose two)
A. spanning tree protocol
B. VRF-lite
C. Distributed anycast gateway
D. DC interconnect
E. Inter-site network
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.
A company needs a solution to virtualize their legacy desktop computers. The solution must be highly resilient and able to withstand the loss of a data center site. Each compute node requires a minimum of 20 disk drives.
Which solution meets these requirements?
A. 1. thin client installed at each user's end station with a separate profile to retrieve sensitive data using the RDP protocol
2. solution based on Cisco HX220 compute nodes
B. 1. data center site with a strict security policy that provides access to users using a bespoke software client
2. solution based on Cisco HX240 compute nodes
C. 1. virtual desktop infrastructure solution installed in multiple data centers that are close to the end users
2. solution based on Cisco HX240 compute nodes
D. 1. dedicated virtual machine per hypervisors for each user in a centralized data center
2. solution based on Cisco HX220 compute nodes
