Which three main problems was a host overlay system designed to address? (Choose three.)

B. simplified and automated workload provisioning
C. multitenancy at scale
D. integrate physical and virtual networking
E. increase visibility to traffic flows
F. better root cause analysis capabilities
G. consolidate IT infrastructure teams
Which two benefits of ACI help improve the time required to deploy an application? (Choose two.)
A. enabling software developers to create development environments similar to production
B. eliminating the need for expensive Layer 4 to Layer 7 service appliances
C. eliminating IP addressing from software stacks
D. evolving the IT model from manual workflows to an application model that automates deployment, operations, and visibility
Which four options are important functions offered by the Cisco APIC? (Choose four.)
A. fault and event management
B. hypervisor, storage, and computing management
C. Layer 3 through 5 services integration
D. statistical collection and analysis
E. performance management
F. nonblocking data plane
G. 1.5:1 oversubscribed ports
H. BGP and OSPF routing protocol support
You want to satisfy the business, risk, and customer requirements. Which option is a consideration when you select and design an ACI fabric?
A. the requirement for meaningful services (such as traffic load balancing, segmentation, filtering, traffic insertion, and monitoring) for workloads provided by virtual Layer 4 to Layer 7 servers
B. virtual machine mobility because moving from one server to another one would have to occur on the same leaf so that ACI can preserve virtual machine visibility and policy enforcement
C. the breakdown of virtual versus physical workloads because virtual workloads are treated preferentially in ACI
D. the requirement for a central point of management, but no centralized control plane
Which two options are two provisions of ACI for security? (Choose two.)
A. Security services are provided by the fabric, without the need for external appliances.
B. ACI depends on external appliances and software to provide security.
C. ACI provides a stateless whitelist approach for all traffic in the fabric.
D. ACI allows for easy integration of external stateful physical and virtual security devices into the fabric.
Which three options are the primary benefits of a leaf-spine architecture? (Choose three.)
A. linear scalability
B. robust multipathing
C. use of Rapid PVST
D. deterministic latency
E. increased scalability of the proxy database
F. 1.5:1 oversubscribed ports
G. best suited for integration into an access/aggregation/core topology
If flowlet switching and dynamic flow prioritization are enabled, which two statements about ACI fabric load balancing are true? (Choose two.)
A. A flowlet is a subset of a TCP/UDP flow that is composed of packets that are part of the same bursts of packets.
B. A flowlet is a subset of a TCP/UDP flow that is composed of packets of approximately the same size (64 bytes to 127 is flowlet 1, 128 to 255 is flowlet 2, ...).
C. The first few identified flowlets of a TCP/UDP flow are treated with a higher priority than the last flowlet of the same TCP/UDP flow.
D. Each flowlet of a TCP/UDP flow is treated with same priority and takes the same path to avoid out-oforder packets.
E. The egress leaf reorders out-of-order packets when flowlet switching is used.
Which three options are the major components of the ACI fabric? (Choose three.)
A. bidirectional optics
B. Application Policy Infrastructure Controller
C. spine switches
D. directory service nodes
E. leaf switches
F. Layer 4 to Layer 7 service devices

A. Layer 3 interface
B. subinterface with 802.1Q tagging
C. backup interface
D. switched virtual interface
E. management interface
F. point-to-point interface
