Cisco Designing with Cisco Network Programmability for ACI (NPDESACI) Sample Questions:
1. For which ACI constructs are health scores calculated?
A) filters
B) bridge domains
C) service graphs
D) service device clusters
E) contracts
2. Which statement about the infrastructure requirements for an ACI fabric is true?
A) Hypervisors that connect to the ACI fabric must support the Cisco Discovery Protocol so that ACI can discover the presence of virtualized hosts and deploy policies to the ports on which a virtualized host is present.
B) The Cisco Nexus 9336PQ form factor is well suited for large enterprise ACI deployments because it provides 288 40 Gigabit Ethernet ports at the spine.
C) Leaf and spine switches can connect at 40 Gbps with multimode fiber by using the Cisco 40 Gbps short-reach bidirectional QSFP optics modules, which do not require new cabling.
D) The Cisco ACI fabric uses an overlay, based on MPLS VPN, to virtualize the physical infrastructure. This overlay maps the tenant endpoint addresses to the location of the endpoint using the tunnel endpoint.
3. Which three elements of the ACI fabric contribute to zero-touch deployment capability? (Choose three.)
A) centralized controller for policy, bootstrap, and image management
B) orchestration using Visore
C) loose wiring validation
D) topology auto discovery, automated configuration, and infrastructure addressing
E) NX-API and NETCONF protocol interfaces
F) support for iBGP confederations
4. Which statement about designing a migration approach of an existing Data Center network to Cisco ACI is true?
A) The service nodes must be moved first because Layer 4 to Layer 7 services (FW/LB) in the existing network will not be functional during migration.
B) When migration is complete, the existing Layer 3 devices should still serve as the default gateway.
C) Simplify the migration by associating every EPG to a VLAN.
D) The first action is to connect the Cisco APIC to the existing core Layer 3 routers so that the APIC can begin to be involved in traffic forwarding.
5. Which two methods to scale bandwidth and capacity enable capacity planning and scaling in the ACI fabric? (Choose two.)
A) Scale-out leaf nodes for capacity.
B) Increase Cisco APIC uplinks to fabric for bandwidth.
C) Scale-out spine nodes for bandwidth.
D) Interconnect spine nodes.
E) Leverage QoS on the Cisco APIC uplinks.
