Exam 44: Deploying Cisco Unified Contact Center Express

Refer to the exhibit. Assume that no multicast optimization is done on LAN switches A and B. Which feature can be used to optimize multicast traffic forwarding in this situation?

Refer to the exhibit. You are developing a migration plan to enable IPv6 in your IPv4 network. Starting at R3 and assuming default IS-IS operations, what is likely to happen when you enable IPv6 routing on the link from R3 to R2?

Which item is the primary requirement when deploying OSPF graceful restart on a router?

You have been hired to redesign a network due to issues with congestion. How will a router function if the QoS mechanism of congestion avoidance is integrated into the existing network design?

During periods of congestion, which two impacts are of traffic shaping on traffic flows? (Choose two.)

A service provider hires you to design its new managed CE offering to meet these requirements: The CEs cannot run a routing protocol with the PE Provide the ability for equal or unequal ingress load balancing in dual-homed CE scenarios Provide support for IPv6 customer routes Scale up to 250,000 CE devices per customer Provide low operational management to scale customer growth Utilize low-end (inexpensive) routing platforms for CE functionality Which tunneling technology do you recommend?

You are evaluating convergence characteristics of various interior gateway protocols for a new network design. Which technology allows link-state routing protocols to calculate paths to destination prefixes that are functionally similar to feasible successors in Enhanced Interior Gateway Routing Protocol?

While adjusting the LSA generation time in OSPF, which two factors should be taken into consideration? (Choose two.)

A large enterprise company is redesigning their WAN infrastructure and has these design requirements: The Frame Relay WAN infrastructure will be replaced with an MPLS VPN service. BGP is the PE-CE routing protocol adopted for this scenario. There are 3000 routes in the routing database of the distribution routers. All 3000 routes will be advertised from the access routers through the MPLS network. The service provider that provides this MPLS VPN service supports only 1000 prefixes per VRF. Which two design solutions ensure that the enterprise access routers reach all devices in this enterprise network? (Choose two.)

You are a network administrator for the P4S company, study the exhibit carefully. You are responsible for this small EIGRP network and you want to change the primary path from P4S-R5 to 10.1.2.0/24 so it passes through P4S-R2. How to modify the EIGRP metrics to change the path in this way?

You are the Cisco Network Designer in P4S. Which of these practices should you follow when designing a Layer 3 routing protocol?

When a multiprotocol environment is designed to have several routers redistribute among the routing domains, how can routing loops be avoided?

You are implementing a one-to-many multicast solution for a large service provider network. Which technology offers optimal routing of multicast traffic?

What is a key role for the access layer in a hierarchical network design?

The P4S company is deploying OSPF on a point-to-multipoint Frame Relay network. The remote sites needn??t to communicate with each other and there are a relatively small number of sites (scaling is not a concern). How to configure OSPF for this topology in order to minimize the additional routing information injected into the network and keep the configuration size and complexity to a minimum?

Refer to the exhibit. You are a network designer who is given these design requirements: Multicast services must be provided for Layer 3 VPN customers The same forwarding technology must be used as Layer 3 VPN unicast packets Replication of multicast traffic is not allowed on the ingress PE Which multicast VPN technology conforms to the design requirements?

You are developing the routing design for two merging companies that have overlapping IP address space. Which of these must you consider when developing the routing and NAT design?

A company wants to use SSM as the multicast routing protocol inside its network. Some of its multicast applications do not support IGMPv3. In which two ways can the mapping be done when these applications send IGMPv2 join messages? (Choose two.)

A company plans to establish a new network using Cisco Catalyst switches for its multicast applications. What is the disadvantage when two multicast applications are using the multicast IP addresses 234.17.4.5 and 234.145.4.5 inside the same network?

A senior network designer suggests that you should improve network convergence times by reducing BGP timers between your CE router and the PE router of the service provider. Which three factors should you to consider when you adjust the timer values? (Choose three.)
