1. A company uses a cloud-based payroll system. Which cloud

computing technology is this company using?
 browser as a service (BaaS)
 infrastructure as a service (IaaS)
 software as a service (SaaS)
 wireless as a service (WaaS)
2. For a data center, what is the difference in the server
virtualization data traffic compared with the traditional client-
server model?
 Data traffic from clients will be routed to multiple virtual servers.
 There are significant data exchanges between virtual
servers.
 There is more data traffic flowing from virtual servers to clients.
 More network control traffic is generated between virtual servers and clients.
3. Which component in a traditional infrastructure device
provides Layer 2 and Layer 3 functions to create data paths
within a network?
 data plane
 control plane
 adjacency table
 forwarding information base
4. Which network traffic management technology is a basic
element in SDN implementations?
 OpenFlow
 OpenStack
 IEEE 802.1aq
 Interface to the Routing System
5. Which type of hypervisor would most likely be used in a data
center?
 Type 2
 Type 1
 Nexus
 Hadoop
Explanation: The two type of hypervisors are Type 1 and Type 2. Type 1 hypervisors
are usually used on enterprise servers. Enterprise servers rather than virtualized PCs are
more likely to be in a data center.
6. Which is a characteristic of a Type 1 hypervisor?
 installed directly on a server
 best suited for consumers and not for an enterprise environment
 does not require management console software
 installed on an existing operating system
Explanation: Type 1 hypervisors are installed directly on a server and are known as
“bare metal” solutions giving direct access to hardware resources. They also require a
management console and are best suited for enterprise environments.
7. Which two layers of the OSI model are associated with SDN
network control plane functions that make forwarding
decisions? (Choose two.)
 Layer 1
 Layer 2
 Layer 3
 Layer 4
 Layer 5
Explanation: The SDN control plane uses the Layer 2 ARP table and the Layer 3
routing table to make decisions about forwarding traffic.
8. What pre-populates the FIB on Cisco devices that use CEF to
process packets?
 the routing table
 the adjacency table
 the ARP table
 the DSP
Explanation: CEF uses the FIB and adjacency table to make fast forwarding decisions
without control plane processing. The adjacency table is pre-populated by the ARP table
and the FIB is pre-populated by the routing table.
9. What is a function of the data plane of a network device?
 sending information to the CPU for processing
 building the routing table
 resolving MAC addresses
 forwarding traffic flows
Explanation: Networking devices operate in two planes; the data plane and the control
plane. The control plane maintains Layer 2 and Layer 3 forwarding mechanisms using the
CPU. The data plane forwards traffic flows.
10. Which statement describes the concept of cloud computing?
 separation of application from hardware
 separation of management plane from control plane
 separation of operating system from hardware
 separation of control plane from data plane
Explanation: Cloud computing is used to separate the application or service from
hardware. Virtualization separates the operating system from the hardware.
11. Which cloud model provides services for a specific
organization or entity?
 a public cloud
 a hybrid cloud
 a private cloud
 a community cloud
Explanation: Private clouds are used to provide services and applications to a specific
organization and may be set up within the private network of the organization or managed
by an outside organization.
12. What two benefits are gained when an organization adopts
cloud computing and virtualization? (Choose two.)
 provides a “pay-as-you-go” model, allowing organizations
to treat computing and storage expenses as a utility
 enables rapid responses to increasing data volume
requirements
 distributed processing of large data sets in the size of terabytes
 elimination of vulnerabilities to cyber attacks
 increases the dependance on onsite IT resources
Explanation: Organizations can use virtualization to consolidate the number of
required servers by running many virtual servers on a single physical server. Cloud
computing allows organizations to scale their solutions as required and to pay only for the
resources they require.
13. Which type of Hypervisor is implemented when a user with a
laptop running the Mac OS installs a Windows virtual OS
instance?
 type 2
 virtual machine
 type 1
 bare metal
Explanation: Type 2 hypervisors, also know as hosted hypervisors, are installed on top
of an existing operating system, such as Mac OS, Windows, or Linux.
14. A small company is considering moving many of its data
center functions to the cloud. What are three advantages of this
plan? (Choose three.)
 The company only needs to pay for the amount of
processing and storage capacity that it uses.
 Cloud services are billed at a fixed fee no matter how much processing and storage
are used by the company.
 The company does not need to be concerned about how to
handle increasing data storage and processing demands with
in-house data center equipment.
 The company can increase processing and storage capacity
as needed and then decrease capacity when it is no longer
needed.
 Single-tenant data centers can easily grow to accommodate increasing data storage
requirements.
 Cloud services enable the company to own and administer its own servers and
storage devices.
Explanation: Cloud computing offers many advantages to the company. Since the
cloud data storage and processing facilities are owned by third-parties, the company does
not need to be concerned about how it will handle increasing data storage and processing
demands with its own data center equipment. The company can easily increase or decrease
processing power and storage capacity based on need. Also, cloud services are billed by
usage, so the company does not have the costs of supporting its own expensive data center
that is not always used to maximum capacity.
15. How does virtualization help with disaster recovery within a
data center?
 support of live migration
 guarantee of power
 improvement of business practices
 supply of consistent air flow
Explanation: Live migration allows moving of one virtual server to another virtual
server that could be in a different location that is some distance from the original data
center.
16. What technology allows users to access data anywhere and
at any time?
 Cloud computing
 virtualization
 micromarketing
 data analytics
Explanation: Cloud computing allows organizations to eliminate the need for on-site
IT equipment, maintenance, and management. Cloud computing allows organizations to
expand their services or capabilities while avoiding the increased costs of energy and space.
17. Which action takes place in the assurance element of the
IBN model?
 verification and corrective action
 configuring systems
 translation of policies
 integrity checks
Explanation: The assurance element of the IBN model is concerned with end-to-end
verification of network-wide behavior.
 18. Refer to the exhibit. Which data format is used to represent
the data for network automation applications?

 XML
 YAML
 HTML
 JSON
Explanation: The common data formats that are used in many applications including
network automation and programmability are as follows:
 JavaScript Object Notation (JSON) – In JSON, the data known as an
object is one or more key/value pairs enclosed in braces { }. Keys must be strings within
double quotation marks ” “. Keys and values are separated by a colon.
 eXtensible Markup Language (XML) – In XML, the data is enclosed
within a related set of tags <tag>data</tag>.
 YAML Ain’t Markup Language (YAML) – In YAML, the data known as
an object is one or more key value pairs. Key value pairs are separated by a colon
without the use of quotation marks. YAML uses indentation to define its structure,
without the use of brackets or commas.
19. What is the function of the key contained in most RESTful
APIs?
 It is the top-level object of the API query.
 It is used to authenticate the requesting source.
 It represents the main query components in the API request.
 It is used in the encryption of the message by an API request.
Explanation: Many RESTful APIs, including public APIs, require a key. The key is
used to identify the source of the request through authentication.
20. Which two configuration management tools are developed
using Ruby? (Choose two.)
 Puppet
 Ansible
 SaltStack
 Chef
 RESTCONF
Explanation: Chef and Puppet are configuration management tools developed using
Ruby. Ansible and SaltStack are configuration management tools developed using Python.
 Ruby is typically considered a more difficult language to learn than Python. RESTCONF is
a network management protocol.
21. Which term is used to describe a set of instructions for
execution by the configuration management tool Puppet?
 Playbook
 Cookbook
 Manifest
 Pillar
Explanation: The configuration management tool Puppet uses the name Manifest to
describe the set of instructions to be executed.
22. Which term is used to describe a set of instructions for
execution by the configuration management tool SaltStack?
 Cookbook
 Manifest
 Pillar
 Playbook
Explanation: The configuration management tool SaltStack uses the name Pillar to
describe the set of instructions to be executed.
23. Which scenario describes the use of a public API?
 It requires a license.
 It can be used with no restrictions.
 It is used between a company and its business partners.
 It is used only within an organization.
Explanation: Public, or open, APIs have no restrictions and are available to the public.
Some API providers do require a user to obtain a free key or token prior to using the API in
order to control the volume of API requests received and processed.
24. What is YAML?
 It is a scripting language.
 It is a data format and superset of JSON.
 It is a compiled programming language.
 It is a web application.
Explanation: Like JSON, YAML Ain’t Markup Language (YAML) is a data format
used by applications to store and transport data. YAML is considered a superset of JSON.
25. Which RESTFul operation corresponds to the HTTP GET
method?
 post
 patch
 update
 read
Explanation: RESTful operations correspond to the following HTTP methods (shown
to the left with the RESTful operation on the right):
 POST > Create
 GET > Read
 PUT/PATCH > Update
 DELETE > Delete
26. Which technology virtualizes the network control plane and
moves it to a centralized controller?
 SDN
 fog computing
 cloud computing
 IaaS
Explanation: Networking devices operate in two planes: the data plane and the control
plane. The control plane maintains Layer 2 and Layer 3 forwarding mechanisms using the
CPU. The data plane forwards traffic flows. SDN virtualizes the control plane and moves it
to a centralized network controller.
27. What are two functions of hypervisors? (Choose two.)
 to partition the hard drive to run virtual machines
 to manage virtual machines
 to protect the host from malware infection from the virtual machines
 to share the antivirus software across the virtual machines
 to allocate physical system resources to virtual machines
Explanation: The hypervisor does not protect the hosting OS from malware. Neither
does it allow sharing software across virtual machines. The hard drive of the supporting
computer does not need to be partitioned to run virtual machines. The hypervisor creates
and manages virtual machines on a host computer and allocates physical system resources
to them.
28. What is a difference between the functions of Cloud
computing and virtualization?
 Cloud computing requires hypervisor technology whereas virtualization is a fault
tolerance technology.
 Cloud computing separates the application from the
hardware whereas virtualization separates the OS from the
underlying hardware.
 Cloud computing provides services on web-based access whereas virtualization
provides services on data access through virtualized Internet connections.
 Cloud computing utilizes data center technology whereas virtualization is not used
in data centers.
Explanation: Cloud computing separates the application from the hardware.
Virtualization separates the OS from the underlying hardware. Virtualization is a typical
component within cloud computing. Virtualization is also widely used in data centers.
Although the implementation of virtualization facilitates an easy server fault tolerance
setup, it is not a fault tolerance technology by design. The Internet connection from a data
center or service provider needs redundant physical WAN connections to ISPs.
29. How is the YAML data format structure different from JSON?
 It uses indentations.
 It uses end tags.
 It uses hierarchical levels of nesting.
 It uses brackets and commas.
Explanation: The structure in YAML is defined by indentations rather than brackets
and commas.
30. What is the most widely used API for web services?
 XML-RPC
 SOAP
 JSON-RPC
 REST
Explanation: REST accounts for more than 80% of all API types used for web
services, making it the most widely used web service API.
31. What is REST?
 It is a way to store and interchange data in a structured format.
 It is an architecture style for designing web service
applications.
 It is a human readable data structure that is used by applications for storing,
transforming, and reading data.
 It is a protocol that allows administrators to manage nodes on an IP network.
Explanation: REST is not a protocol or service, but rather a style of software
architecture for designing web service applications.
32. What is a difference between the XML and HTML data
formats?
 XML does not use predefined tags whereas HTML does use
predefined tags.
 XML encloses data within a pair of tags whereas HTML uses a pair of quotation
makes to enclose data.
 XML formats data in binary whereas HTML formats data in plain text.
 XML does not require indentation for each key/value pair but HTML does require
indentation.
Explanation: XML is a human readable data structure used to store, transfer, and read
data by applications. Like HTML, XML uses a related set of tags to enclose data. However,
unlike HTML, XML uses no predefined tags or document structure.
33. To avoid purchasing new hardware, a company wants to take
advantage of idle system resources and consolidate the number
of servers while allowing for multiple operating systems on a
single hardware platform. What service or technology would
support this requirement?
 dedicated servers
 Cisco ACI
 virtualization
 software defined networking
34. Match the term to the RESTful API request

35. Which cloud computing opportunity would provide the use of

network hardware such as routers and switches for a particular
company?
 software as a service (SaaS)
 wireless as a service (WaaS)
 infrastructure as a service (IaaS)
 browser as a service (BaaS)
Explanation: This item is based on information contained in the presentation.
Routers, switches, and firewalls are infrastructure devices that can be provided in the cloud.
36. What component is considered the brains of the ACI
architecture and translates application policies?
 the Application Network Profile endpoints
 the Nexus 9000 switch
 the hypervisor
 the Application Policy Infrastructure Controller
Explanation: The ACI architecture consists of three core components: the Application
Network Profile, the Application Policy Infrastructure Controller, which serves as the
brains of the ACI architecture, and the Cisco Nexus 9000 switch.
37. Which statement describes the concept of cloud computing?
 separation of management plane from control plane
 separation of control plane from data plane
 separation of application from hardware
 separation of operating system from hardware
Explanation: Cloud computing is used to separate the application or service from
hardware. Virtualization separates the operating system from the hardware.
38. In which situation would a partner API be appropriate?
 an internet search engine allowing developers to integrate the search engine into
their own software applications
 company sales staff accessing internal sales data from their mobile devices
 someone creating an account on an external app or website by using his or her
social media credentials
 a vacation service site interacting with hotel databases to
display information from all the hotels on its web site
Explanation: Partner API programs incorporate collaboration with other business.
They facilitate communication and integration of software between a company and its
business partners.
39. Because of enormous growth in web traffic, a company has
planned to purchase additional servers to help handle the web
