Question: 2
Which network allows devices to communicate without the need to access the Internet?
A. 1729.0.0/16
B. 172.28.0.0/16
C. 192.0.0.0/8
D. 209.165.201.0/24
Answer: B
The private ranges of each class of IPv4 are listed below:
Class A private IP address ranges from 10.0.0.0 to 10.255.255.255 Class B private IP address ranges from
172.16.0.0 to 172.31.255.255 Class C private IP address ranges from 192.168.0.0 to 192.168.255.255
Only the network 172.28.0.0/16 belongs to the private IP address (of class B
Question: 3
Which result occurs when PortFast is enabled on an interface that is connected to another switch?
A. Spanning tree may fail to detect a switching loop in the network that causes broadcast storms
B. VTP is allowed to propagate VLAN configuration information from switch to switch automatically.
C. Root port choice and spanning tree recalculation are accelerated when a switch link goes down
D. After spanning tree converges PortFast shuts down any port that receives BPDUs.

Enabling the PortFast feature causes a switch or a trunk port to enter the STP forwarding-state
immediately or upon a linkup event, thus bypassing the listening and learning states.
Note: To enable portfast on a trunk port you need the trunk keyword “spanning-tree portfast trunk

Question: 8
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. software-as-a-service
C. network-as-a-service
D. infrastructure-as-a-service
Answer: D
Below are the 3 cloud supporting services cloud providers provide to customer:
+ SaaS (Software as a Service): SaaS uses the web to deliver applications that are managed by a
thirdparty 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.
+ 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
thirdparty provider, can manage OSes, virtualization, servers, storage, networking, and the PaaS
software itself. Developers, however, manage the applications.
+ 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.
Question: 13
What are two characteristics of a controller-based network? (Choose two)
A. The administrator can make configuration updates from the CLI
B. It uses northbound and southbound APIs to communicate between architectural layers

Question: 16
Which attribute does a router use to select the best path when two or more different routes to the
same destination exist from two different routing protocols.
A. dual algorithm
B. metric
C. administrative distance
D. hop count
Answer: C
Administrative distance is the feature used by routers to select the best path when there are two or
more different routes to the same destination from different routing protocols. Administrative distance
defines the reliability of a routing protocol.
