• Question 66:

  What are two southbound APIs? (Choose two.)

  A. Thrift

  B. DSC

  C. CORBA

  D. NETCONF

  E. OpenFlow

  Correct Answer: DE

  OpenFlow is a well-known southbound API. OpenFlow defines the way the SDN Controller should interact with the forwarding plane to make adjustments to the network, so it can better adapt to changing business requirements.

  The Network Configuration Protocol (NetConf) uses Extensible Markup Language (XML) to install, manipulate and delete configuration to network devices.

  Other southbound APIs are:

  1.

  onePK: a Cisco proprietary SBI to inspect or modify the network element configuration without hardware upgrades.

  2.

  OpFlex: an open-standard, distributed control system. It send “summary policy” to network elements.

• Question 67:

  Refer to the exhibit.

  

  A network administrator is configuring an EtherChannel between SW1 and SW2. The SW1 configuration is shown.

  What is the correct configuration for SW2?

  A. interface FastEthernet 0/1 channel-group 1 mode active switchport trunk encapsulation dot1q switchport mode trunk interface FastEthernet 0/2 channel-group 1 mode active switchport trunk encapsulation dot1q switchport mode trunk

  B. interface FastEthernet 0/1 channel-group 2 mode auto switchport trunk encapsulation dot1q switchport mode trunk interface FastEthernet 0/2 channel-group 2 mode auto switchport trunk encapsulation dot1q switchport mode trunk

  C. interface FastEthernet 0/1 channel-group 1 mode desirable switchport trunk encapsulation dot1q switchport mode trunk interface FastEthernet 0/2 channel-group 1 mode desirable switchport trunk encapsulation dot1q switchport mode trunk

  D. interface FastEthernet 0/1 channel-group 1 mode passive switchport trunk encapsulation dot1q switchport mode trunk interface FastEthernet 0/2 channel-group 1 mode passive switchport trunk encapsulation dot1q switchport mode trunk

  Correct Answer: C

  If the etherchannel was configured with mode "auto", it was using PagP, so, we need to configure the other switch with "desirable" mode.

  PagP modes: auto | Desirable LACP modes: active | pasive

• Question 68:

  Which API is used in controller-based architectures to interact with edge devices?

  A. southbound

  B. overlay

  C. northbound

  D. underlay

  Correct Answer: A

• Question 69:

  What makes Cisco DNA Center different from traditional network management applications and their management of networks?

  A. Its modular design allows someone to implement different versions to meet the specific needs of an organization.

  B. It only supports auto-discovery of network elements in a greenfield deployment.

  C. It does not support high availability of management functions when operating in cluster mode.

  D. It abstracts policy from the actual device configuration.

  Correct Answer: D

  The primary characteristic and difference is still the separation of control and data plane:

  How is the policy abstract or abstracted from the device configuration?

  -It is separated from the device configuration. It is implemented on a higher, centralized level.

  -It is configured (mostly) in a GUI, which is a different way of interfacing than on the devices themselves.

  A is aiming more for qualities like for example scalability. And the way the sentence is worded would imply that traditional networking is not scalable (or very limited) to the needs of an organization.

• Question 70:

  An organization has decided to start using cloud-provided services. Which cloud service allows the organization to install its own operating system on a virtual machine?

  A. platform-as-a-service

  B. network-as-a-service

  C. software-as-a-service

  D. infrastructure-as-a-service

  Correct Answer: D

  Below are the 3 cloud supporting services cloud providers provide to customer:

  1.

  SaaS (Software as a Service): SaaS uses the web to deliver applications that are managed by a third-party vendor and whose interface is accessed on the clients’ side. Most SaaS applications can be run directly from a web browser without any downloads or installations required, although some require plugins.

  2.

  PaaS (Platform as a Service): are used for applications, and other development, while providing cloud components to software. What developers gain with PaaS is a framework they can build upon to develop or customize applications. PaaS makes the development, testing, and deployment of applications quick, simple, and cost-effective. With this technology, enterprise operations, or a third-party provider, can manage OSes, virtualization, servers, storage, networking, and the PaaS software itself. Developers, however, manage the applications.

  3.

  IaaS (Infrastructure as a Service): self-service models for accessing, monitoring, and managing remote datacenter infrastructures, such as compute (virtualized or bare metal), storage, networking, and networking services (e.g. firewalls). Instead of having to purchase hardware outright, users can purchase IaaS based on consumption, similar to electricity or other utility billing.

  In general, IaaS provides hardware so that an organization can install their own operating system.
