B. VSS
C. vPC
D. 802.1q
E. FEX
Which mode must be enabled on a Cisco UCS Fabric Interconnect to connect directly to a storage array?
A. NPIV mode
B. FC end-host mode
C. NPV mode
D. FC switching mode
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
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
An engineer must design a disaster recovery solution for a Cisco ACI Multi-Site network. One requirement is that the applications must have seamless IP addressing across sites. The solution must also be highly resilient and support Layer 2 adjacency.
Which design meets these requirements?
A. localized bridge domain, subnet, and EPG stretched Layer 2 broadcast domain
B. stretched bridge domain with local subnet stretched Layer 2 broadcast domain
C. localized bridge domain with local subnet localized Layer 2 broadcast flooding
D. stretched bridge domain, subnet, and EPG localized Layer 2 broadcast flooding
An engineer must design a VXLAN EVPN network. The solution should optimize broadcast, unknown unicast, and multicast (BUM) and short BUM replication, and use PIM anycast RP.
Which solution should be included in the design?
A. PIM sparse mode
B. ingress replication
C. head-end replication
D. PIM dense mode
An engineer enables the HSRP feature on a Cisco Nexus 7000 Series Switch. It must be ensured that the switch manages packets that are sent to the local vPC MAC address, remote vPC MAC address, and HSRP virtual MAC address.
Which command accomplishes this goal?
A. peer-switch
B. peer-gateway
C. map-server
D. hsrp preempt
An engineer must develop a Python tool to automate software upgrades of both data center and non-data center devices. All devices offer a RESTful API and require a JSON or XML payload Vendor-specific libraries must be avoided. Which library must the engineer choose?
A. requests
B. Nornir
C. ncciient
D. Netmiko
A data center uses Cisco Nexus 7000 Series Switch and contains two tenants, tenant A and tenant B.
1.
Tenant A uses IP addresses in the 10.2.30.41/24 to 10.2.30.64/24 range.
2.
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:
1.
Isolates the traffic for each tenant as separate routing data and control planes.
2.
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.)
A. VDC
B. vPC
C. VXLAN
D. VLAN
E. VRF
A company purchased a Cisco UCS system with four 5108 Chassis populated with UCS B-Series servers. The environment consists of nine Cisco HyperFlex rack servers. An engineer must provision virtual machines using an orchestration tool to optimize overall deployment time.
Which orchestration must be used to meet this requirement?
A. Cisco Intersight
B. Cisco DNA Center
C. Cisco AppDynamic
D. Cisco Network Assurance
