Which type of structure consists of the addressing, routing protocols, QoS, and security components?
What phase of Cisco’s PPDIOO is the final test of the appropriateness of the design?
What phase of Cisco’s PPDIOO includes the identification and resolution of issues prior to moving the entire network to production?
You are tasked with designing a new branch office that will support 75 users with possible expansion in the future and will need a highly available network.
Which of the branch design profiles should be implemented?
A. large branch design
B. medium branch design
C. teleworker design
D. small branch design
Medium Branch Design
The medium branch design is recommended for branch offices of 50 to 100 users, which is similar to the small branch but with an additional access router in the WAN edge (slightly larger) allowing for redundancy services. Typically, two 2921 or 2951 routers are used to support the WAN, and separate access switches are used to provide LAN connectivity.
Which four services does the architecture for Media Services contain? (Choose four.)
A. access services
B. transport services
C. storage services
D. forwarding services
E. session control services
F. security services
G. filtering services
H. remote access services
An architecture framework for media services supports different models of video models. As shown in Figure 14-13, the network provides service to video media in the Media Services Framework. Those services are access services, transport services, bridging services, storage servers, and session control services, which arc provided to endpoints. Access services provide identity of end devices, mobility, and location services. Transport services provide QoS for reliable packet delivery. Bridging services provide transcoding, conferencing, and recording services of media streams.
Storage services provide capture and storage of media streams and content management and distribution. Session control services provide session signaling and control and gateway services.
Which two are types of network virtualization? (Choose two.)
A. VSS: Virtual Switching System
B. VRF: virtual routing and forwarding
C. VCI: virtual channel identifier
D. VLSM: variable length subnet masking
E. VM: virtual machine
F. VMP: Virtual Memory Pool
Network virtualization encompasses logical isolated network segments that share the same physical infrastructure. Each segment operates independently and is logically separate from the other segments. Each network segment appears with its own privacy, security, independent set of policies, QoS levels, and independent routing paths. Here are some examples of network virtualization technologies:
VLAN: Virtual local-area network
VSAN: Virtual storage-area network
VRF: Virtual routing and forwarding
VPN: Virtual private network
VPC: Virtual Port Channel
You want to gather as much detail as possible during a network audit, to include data time stamping across a large number of interfaces, customized according to interface, with a minimal impact on the network devices themselves.
Which tool would you use to meet these requirements?
D. Cisco Discovery Protocol
NetFlow provides extremely granular and accurate traffic measurements and a high-level collection of aggregated traffic. The output of netflow information is displayed via the show ip cache flow command on routers. The Table shows a description of the fields for NetFlow output.
Table. Netflow Output escription
Which two can be used as a branch office WAN solution? (Choose two.)
A. frame relay
C. Metro Ethernet
E. dial-up modem
F. 3G USB modems
Frame relay is old ‘shared’ technology today’s sites use some flavor or Metro E or MPLS/VPN
Which IPv6 feature enables routing to distribute connection requests to the nearest content server?
E. Global aggregatable
Any cast is a network addressing and routing methodology in which data grams from a single sender are routed to the topologically nearest node in a group of potential receivers all identified by the same destination address.
Which protocol is used to reserve bandwidth for the transport of a particular application data flow across the network?
B. IEEE 802.1P
E. Auto QOS
RSVP Signaling protocol that enables end stations or applications to obtain guaranteed bandwidth and low delays for their data flows.
Cisco Identity-Based Networking Services relies heavily on the 802.1X protocol. Which other authentication solution is used hand-in-hand with 802.1X to authenticate users for network access?
Cisco Identity-Based Network Services
The Cisco Identity-Based Network Services solution is a way to authenticate host access based on policy for admission to the network. IBNS supports identity authentication, dynamic provisioning of VLANs on a per-user basis, guest VLANs, and 802.1X with port security.
The 802.1 X protocol is a standards-based protocol for authenticating network clients by permitting or denying access to the network. The 802.1 X protocol operates between the end-user client seeking access and an Ethernet switch or wireless access point (AP) providing the connection to the network. In 802.1 X terminology, clients are called supplicants, and switches and APs are called authenticates. A back-end RADIUS server such as a Cisco Access Control Server (ACS) provides the user account database used to apply authentication and authorization.
With an IBNS solution, the host uses 802.IX and Extensible Authentication Protocol over LANs (EAPoL) to send the credentials and initiate a session to the network. After the host and switch establish LAN connectivity, username and password credentials are requested. The client host then sends the credentials to the switch, which forwards them to the RADIUS ACS.
The RADIUS ACS performs a lookup on the username and password to determine the credentials’ validity. If the username and password are correct, an accept message is sent to the switch or AP to allow access to the client host. If the username and password are incorrect, the server sends a message to the switch or AP to block the host port. Figure 13-4 illustrates the communication flow of two hosts using 802.1X and KAPoL with the switch, AP, and back-end RADIUS server.
Refer to the exhibit. Which layer is the distribution layer?
A. Layer A
B. Layer B
C. Layer C
D. Layers A and B form a consolidated core and distribution layer
In which phase of PPDIOO are the network requirements identified?
The Plan phase identifies the network requirements based on goals, facilities, and user needs. This phase characterizes sites and assesses the network, performs a gap analysis against best-practice architectures, and looks at the operational environment. A project plan is developed to manage the tasks, responsible parties, milestones, and resources to do the design and implementation. The project plan aligns with the scope, cost, and resource parameters established with the original business requirements. This project plan is followed (and updated) during all phases of the cycle.
Which is the purpose of the Cisco NAC Profiler?
A. Automates discovery and inventory of all LAN attached devices
B. Generates a profile based on username and group
C. Learns and creates a database of virus definitions based on LAN traffic
D. A database used to map user VPN accounts
Cisco NAC Profiler: Enables network administrators to keep a real-time, contextual inventory of all devices in a network. It greatly facilitates the deployment and management of Cisco Network Admission Control (NAC) systems by discovering and tracking the location and type of all LAN-attached endpoints, including those that are not capable of authenticating. It also uses the information about the device to determine the correct policies for NAC to apply.
Which is part of the Prepare phase of PPDIOO?
A. Obtain site contact information
B. Perform network audit
C. Identify customer requirements
D. Perform gap analysis
The Prepare phase establishes organization and business requirements, develops a network strategy, and proposes a high-level conceptual architecture to support the strategy. Technologies that support the architecture are identified. This phase creates a business case to establish a financial justification for a network strategy.
