Question 1

[am4show have=’p2;’]Which component of the Cisco SDN solution serves as the centralized management system?

A. Cisco OpenDaylight
B. Cisco ACI
C. Cisco APIC
D. Cisco IWAN

 

Answer: C[/am4show]

Explanation

The Cisco Application Policy Infrastructure Controller (APIC) is the main architectural component of the Cisco ACI solution. It is the unified point of automation and management for the Cisco ACI fabric, policy enforcement, and health monitoring. The Cisco APIC is a centralized clustered controller that optimizes performance, supports any application anywhere, and unifies operation of physical and virtual environments. The controller manages and operates a scalable multitenant Cisco ACI fabric.

Question 2

[am4show have=’p2;’]Which two options are primary responsibilities of the APIC-EM controller? (Choose two)

A. It automates network actions between different device types.
B. It provides robust asset management.
C. It tracks license usage and Cisco IOS versions.
D. It automates network actions between legacy equipment.
E. It makes network functions programmable.

 

Answer: A E[/am4show]

Question 3

[am4show have=’p2;’]Which Cisco platform can verify ACLs?

A. Cisco Prime Infrastructure
B. Cisco Wireless LAN Controller
C. Cisco APIC-EM
D. Cisco IOS-XE

 

Answer: C[/am4show]

Explanation

In the “CCNA Routing and Switching ICND2 200-105 Official Cert Guide, Academic Edition” there is a section named “Verify ACLs using the APIC-EM Path Trace ACL analysis tool” so APIC-EM should be the correct answer.

    Q1:
    The Cisco APIC provides centralized access to all fabric information, optimizes the application lifecycle for scale and performance, and supports flexible application provisioning across physical and virtual resources.

    Cisco ACI is a comprehensive SDN architecture. This policy-based automation solution supports a business-relevant application policy language, greater scalability through a distributed enforcement system, and greater network visibility.

    Cisco ACI is built on:

    The Application Centric Policy (based on Cisco Application Policy Infrastructure Controller or APIC)
    The Cisco ACI Fabric (based on Cisco Nexus 9000 Series Switches and the Cisco Application Virtual Switch (AVS))
    The Cisco ACI Partner Ecosystem

    Which component of the Cisco SDN solution serves as the centralized management system ?
    A. Cisco OpenDaylight
    B. Cisco ACI
    C. Cisco APIC
    D. Cisco IWAN

    Its B cause ACPI is a part of ACI which does centralized management
    APIC-EM is a controller for managing and operating software-defined networking (SDN).
    Open Daylight – open source SDN controller
    IWAN – provides traffic control and security features for the WAN – automate IWAN feature configuration

    A. Cisco OpenDaylight
    B. Cisco ACI
    C. Cisco APIC
    D. Cisco IWAN
    HIDE ANSWERS
    Answer: B
    Explanation:
    Cisco ACI is a comprehensive SDN architecture. This policy-based automation solution supports a business-relevant application policy language, greater scalability through a distributed enforcement system, and greater network visibility. These benefits are achieved through the integration of physical and virtual environments under one policy model for networks, servers, storage, services, and security.

    ACI is actually the name of Cisco’s SDN solution. The “component” of ACI that is the centralized controller (manager) is Cisco APIC. So I believe the correct answer should be C.

    Regarding Q1
    ACI is whole SDN framework. Management solution within ACI is centralized controller APIC (answer C).
    OpenDaylight controller is also centralized management system, perhaps most centralized. But it’s not Cisco proprietary. Cisco Open SDN Controller is based on OpenDaylight.

    comment from other website :
    The advantages of leased lines include:
    + Simplicity: Point-to-point communication links require minimal expertise to install and maintain.<==== So ANswer: Leased lines require little installation and maintenance expertise. IS CORRECT !!!

    + Quality: Point-to-point communication links usually offer high service quality, if they have adequate bandwidth.
    The dedicated capacity removes latency or jitter between the endpoints. <====== So Answer: Leased lines with sufficient bandwidth can avoid latency between endpoints. IS CORRECT!!!!!

    + Availability: Constant availability is essential for some applications, such as e-commerce. Point-to-point communication links provide permanent, dedicated capacity, which is required for VoIP or Video over IP.

    The disadvantages of leased lines include:
    + Cost: Point-to-point links are generally the most expensive type of WAN access. The cost of leased line solutions can become significant when they are used to connect many sites over increasing distances. In addition, each endpoint requires an interface on the router, which increases equipment costs.
    + Limited flexibility: WAN traffic is often variable, and leased lines have a fixed capacity, so that the bandwidth of the line seldom matches the need exactly <======== therefore answer D IS NOT CORRECT).

    Any change to the leased line generally requires a site visit by ISP personnel to adjust capacity.

    How Does Cisco Network Virtualization Work?

    Cisco network virtualization solutions address three important areas of NV:

    Access Control: Offers secure, customized access to protect the Enterprise LAN from external threats
    Path Isolation: Maps validated users or devices to the correct secure set of available resources
    Services Edge: Allows access to services for legitimate users and devices by utilizing centralized policy enforcement to minimize CapEx and OpEx, share service modules across the network, and quickly deploy services

    Guys, question 1
    Question 1

    Which component of the Cisco SDN solution serves as the centralized management system?
    A. Cisco OpenDaylight
    B. Cisco ACI
    C. Cisco APIC
    D. Cisco IWAN

    IMHO it should be C. Here is text from netacad:

    Application Policy Infrastructure Controller (APIC) – The APIC is considered to be the brains of the ACI architecture. APIC is a centralized software controller that manages and operates a scalable ACI clustered fabric. It is designed for programmability and centralized management. It translates application policies into network programming.

    I have passed my icdn2 exam and got my Cana certificate. My exam consists of 61 questions including four APIC-EM, asking setting options ,pathtrace etc. It was very hard exam.

    Apic has now changed to Cisco DNA which is used in Enterprise. ACI is datacentre.
