Question 1

Question 2

Explanation

Network virtualization architecture has three main components:
+ Network access control and segmentation of classes of users: Users are authenticated and either allowed or denied into a logical partition. Users a
re segmented into employees, contractors and consultants, and guests, with respective access to IT assets. This component identifies users who are authorized to access the network and then places them into the appropriate logical partition.
+ Path isolation: Network isolation is preserved across the entire enterprise: from the edge to the campus to the WAN and back again. This component maintains traffic partitioned over a routed infrastructure and transports traffic over and between isolated partitions. The function of mapping isolated paths to VLANs and to virtual services is also performed in component.
+ Network Services virtualization: This component provides access to shared or dedicated network services such as security, quality of service (QoS), and address management (Dynamic Host Configuration Protocol [DHCP] and Domain Name System [DNS]). It also applies policy per partition and isolates application environments, if required.

Question 3

Explanation

Four technical services are essential to supporting the high level of flexibility, resource availability, and transparent resource connectivity required for cloud computing:

+ The Layer 3 network offers the traditional routed interconnection between remote sites and provides end-user access to cloud services.
+ The extended LAN between two or more sites offers transparent transport and supports application and operating system mobility.
+ Extended SAN services support data access and accurate data replication.
+ IP Localization improves northbound and southbound traffic as well as server-to-server workflows.

Question 6

Explanation

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 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.
+ 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.
+ 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 the context of the three cloud service models (IaaS, PaaS and SaaS), DNS can be considered an IaaS service.

    Cisco Wireless is designed to provide 802.11 wireless networking solutions for enterprises and service providers. Cisco Wireless simplifies deploying and managing large-scale wireless LANs and enables a unique best-in-class security infrastructure. The operating system manages all data client, communications, and system administration functions, performs radio resource management (RRM) functions, manages system-wide mobility policies using the operating system security solution, and coordinates all security functions using the operating system security framework.

    Star is the most popular topology for Ethernet topology but hub and spoke is the most appropriate WAN topology.

    In a Hub-and-spoke network topology, one physical site act as Hub (Example, Main Office or Head Quarter), while other physical sites act as spokes. Spoke sites are connected to each other via Hub site. In Hub-and-spoke topology, the network communication between two spokes always travel through the hub (except when using DMVPN Phase II or Phase III where spokes can communicate with each other directly). The networking device at Hub site is often much more powerful than the ones at spoke sites.

    On Composite Test 1 the question: “Which three technical services support cloud computing?”

    You have as correct answers:
    1) VPN connectivity
    2) redundant connections
    3) extended SAN Services

    But, on the study guide the correct answers are:
    1) layer 3 routing
    2) ip localization
    3) extended SAN services

    Please justify..

    Thank you

    Team,

    on question 3 the answers are: B,C,F (B. layer 3 network routing, C. ip localization, F. extended SAN services) but when i open the quiz the answers are Extended SAN services, redundant connections and VPN connectivity.

    Please advise which are the correct answers and correct them!

    Question number 6
    Which cloud service is typically used to provide DNS and DHCP services to an enterprise?
    A. IaaS
    B. DaaS
    C. SaaS
    D. PaaS

    your explaination :
    But we could not find any information about which service provides DNS and DHCP services.
    so how come your answer is D?

    please anyone know about this?

  35. 9tut
    March 20th, 2018

    @Andre: DNS and DHCP services should belong to “Software” part so SaaS is the best choice.

    @Angel182: We are sorry but we found a small part mentioned about this:

    In the context of the three cloud service models (IaaS, PaaS and SaaS), DNS can be considered an IaaS service.

    Reference: http://searchcloudsecurity.techtarget.com/tip/DNS-attacks-Compromising-DNS-in-the-cloud
    So IaaS is the best choice.
