full mesh What WAN topology is the most expensive and complex to maintain because it has all devices making connections to all other devices. It does provide excellent redundancy of WAN paths through the network? Single homed What WAN topology makes a connection to a single ISP?

MPLS a data carrying technique for high performance telecommunications networks that directs data from one network node to the next based on short path labels rather that long network addresses. Metro ethernet is a MAN that is based on ethernet standards. Commonly used to connect subscribers t a larger service network or the internet. Can also be used by businesses to connect offices. Broadband PPPoE a network protocol for encapsulating PPP frames inside Ethernet frames. Typical use involves leveraging the PPP facilities for authenticating the user with a username and password, predominately via PAP and less often via CHAP. Dynamic Multipoint VPN (DMVPN) a Cisco invention for creating hub-and-spoke topologies with ease, including the dynamic creation of spoke-to-spoke tunnels in order to reduce the burdens on busy HQ (hub) devices. Full-mesh topology What topology requires the highest costs and administrative overhead? A. Full-mesh topology B. Hub-and-spoke topology C. Point-to-point topology D. Single-homed topology Dual-homed topology If your WAN client actually makes connections to two separate ISPs, what kind of topology is this? A. Single-homed topology B. Dual-homed topology C. Point-to-point topology D. Full-mesh topology MPLS What technology uses simple labels instead of complex routing tables for the forwarding of traffic? A. Broadband PPPoE B. Client VPN C. Metro Ethernet D. MPLS Client or SSL VPN What technology might use a web browser to form a secure VPN connection? A. Broadband PPPoE B. Client or SSL VPN C. Metro Ethernet D. MPLS Platform as a Service (PaaS) What cloud model is often used to help enterprises to develop and deploy software applications? Intercloud Exchange What kind of cloud computing organization connects to multiple cloud providers and multiple customers and creates a private network as a service? Infrastructure as a Service the cloud provider makes available to the customer the hardware, software, servers, storage, and other infrastructure components; providers can also host clients' applications and handle tasks such as system maintenance, backup, and resiliency planning. Software as a Service the cloud provider makes powerful software available to clients. Platform as a Service the cloud provider makes virtual machines (VMs) available to clients so that they can develop software applications in a test environment; it is typical for a ________provider to also make available software development tools as part of the platform.

Internet access with VPN D. Cisco Cloud Connect The backbone layer In what layer of a 2-tier architecture is speed most important? A. The workstation layer B. The access layer C. The backbone layer D. The distribution layer Add spine devices If you are using Cisco ACI in your data center and notice that you are starting to run out of overall bandwidth and capacity, what is often the solution to provide the required scalability? A. Upgrade to 1 Gbps links B. Add access devices C. Add spine devices D. Add leaf devices Full-mesh topology Which WAN topology is often the most expensive and difficult to maintain? A. Hub-and-spoke topology B. Full-mesh topology C. Point-to-point topology D. Single-homed topology Elasticity A major reason that many companies are excited about moving to the cloud is that they gain the ability to dynamically resize resources based on demand. What is the term for this ability? A. Elasticity B. Cloud-bursting C. Scalability D. Immutability
