  VoIP Control and Transport Protocols

  A number of different protocols are used in a VoIP environment for call control, device provisioning, and addressing.

  Figure 14-15 shows those protocols focused on VoIP control and transport.

  

• Question 94:

  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
  B. medium 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.

• Question 95:

  You need to connect to a remote branch office via an Internet connection. The remote office does not use Cisco equipment. This connection must be secure and must support OSPF. Which of the following can be used to transport data to the branch office?

  A. GRE over IPsec
  B. IPsec
  C. GRE
  D. IPsec VTI
  A. GRE over IPsec

• Question 96:

  When designing the infrastructure protection portion for the enterprise edge, which solution would be the most appropriate solution to consider?

  A. 802.1X
  B. ACLs in the core layer
  C. Cisco Security MARS
  D. AAA
  D. AAA

• Question 97:

  Which one of these statements describes why, from a design perspective, a managed VPN approach for enterprise teleworkers is most effective?

  A. A managed VPN solution uses a cost-effective, on-demand VPN tunnel back to the enterprise.
  B. This solution supports all teleworkers who do not require voice or video.
  C. This architecture provides centralized management where the enterprise can apply security policies and push configurations.
  D. It provides complete flexibility for remote access through a wireless hotspot or a guest network at a hotel, in addition to a home office.
  C. This architecture provides centralized management where the enterprise can apply security policies and push configurations.

• Question 98:

  A network engineer is following the Cisco enterprise architecture model. To which network layer would a branch office connect to using a private WAN?

  A. Enterprise Campus
  B. Enterprise Edge
  C. SP Edge Premise
  D. Remote Module
  D. Remote Module

• Question 99:

  High availability is a key design consideration in the enterprise campus network. In a fully redundant topology, which is likely to provide faster IGP convergence during a failure?

  A. redundant supervisors
  B. redundant supervisors with Cisco Nonstop Forwarding (NSF) and Stateful Switchover (SSO)
  C. single supervisors with tuned IGP timers
  D. single supervisors
  C. single supervisors with tuned IGP timers

• Question 100:

  Which statement describes a unique advantage of EIGRP?

  A. It enables unequal-cost load balancing.
  B. It enables equal-cost load balancing.
  C. It enables source-based load balancing.
  D. It enables port-based load balancing.
  A. It enables unequal-cost load balancing.
