400-007 Question 82

There are multiple trees in the Cisco FabricPath. All switches in the Layer 2 fabric share the same view of each tree. Which two concepts describe how the multicast traffic is load-balanced across this topology? (Choose two.)

Options:

A specific (S,G) traffic is not load-balanced

All trees are utilized at the same level of the traffic rate

Every leaf node assigns the specific (S,G) to the same tree

A specific (S,G) multicast traffic is load-balanced across all trees due to better link utilization efficiency

The multicast traffic is generally load-balanced across all trees

Traditionally networks handled static web pages e-mail and routine client/server traffic Today enterprise networks must handle more sophisticated types of network applications that include voice and video Applications place increasing demands on IT infrastructures as they evolve into highly visible services that represent the face of the business to internal and external audiences The large amount and variety of data requires that the modern network be aware of the content earned across it to optimally handle that content. Which service provide this intelligence?

Options:

centralized network services

application networking services

network infrastructure services

modular infrastructure services

Questions 84

An external edge router provides connectivity from a service provider to an enterprise. Which two Internet edge best practices meet compliance regulations? (Choose two)

Options:

Implement filtering to control traffic that is sourced from the infrastructure IP space.

Enable and use only secure protocols.

Send logs to a centralized logging collection server.

Implement EBGP to advertise all owned IP blocks.

Use login banners and interface access lists to restrict administrative access to the system.

Company XYZ is a large US-based online retailer that is preparing for a major sale scheduled for the holiday season. Large volumes of dynamic workloads are expected, which are time sensitive and seasonal. In anticipation of the surge in data, they are re-architecting their workload management. Which two technical considerations for service placement of workloads should be considered? (Choose two.)

Options:

service level agreement

performance

time to market

workload elasticity

business asset control

Questions 86

A consultant needs to evaluate project management methodologies for a new service deployment on the existing network of a customer. The customer wants to be involved in the end-to-end project progress and be provided with frequent updates. The customer also wants the ability to change the requirements if needed, as the project progresses. Which project management methodology should be used?

Options:

Three principles

Phased

Agile

Waterfall

Questions 87

Comparing traditional networks with SDN, where the network is only application aware, what is the advantage of SDN architecture?

Options:

has faster network convergence time during catastrophic failures

is resilient to scale with fixed number of network devices

integrates real-time information about networking activity with the applications

simplifies device management by managing each device independently

Questions 88

Refer to the exhibit.

400-007 Question 88

Refer to the exhibit. A new high availability DB server cluster is installed in the network. These two servers require high bandwidth and low latency Layer 2 connectivity for database replication.

Which solution supports these requirements?

Options:

Add two new links between SW1 and SW2 configured as LACP trunk with STP

Add secondary links to REP segments 1 and 2

Add two new links between SW1 and SW2 configured as REP segment 3

Add two new links between SW1 and SW2 configured as REP segments 1 and 2 respectively

Questions 89

In a distributed cloud-native environment, calls to services and cloud resources can fail caused by unanticipated events that will require longer periods of time to resolve. These faults can range in severity from a partial loss of connectivity to the complete failure of a service. In these situations, it ' s pointless for an application to continually retry an operation that is unlikely to succeed. Which pattern can prevent an application from repeatedly trying to execute an operation that ' s likely to fail?

Options:

circuit breaker

bulkhead

fallback

timeout

Questions 90

The goal for any network designer is to strive to build a resilient network that adapts to changing conditions rapidly with minimal impact on the services running over the network. A resilient network can adapt to failures, but which soft failure can be harder to define and detect?

Options:

A network with operational challenges due to lack of skills

A network that is not running in an optimal way

A network which does not solve complexity issues

A network or service that experiences outages
