What are two examples of business goals to be considered when a network design is built? (Choose two.)

  1. integrate endpoint posture
  2. ensure faster obsolescence
  3. minimize operational costs
  4. reduce complexity
  5. standardize resiliency

Answer(s): C,D

Explanation:

-Minimizing operational costs is important because it ensures that the network is affordable to operate and maintain. This can be achieved by using cost-effective hardware and software, and by designing the network in a way that minimizes the need for manual intervention.
-Reducing complexity is important because it makes the network easier to manage and troubleshoot. This can be achieved by using a standardized network architecture, and by using tools that automate network management tasks.

The other options are not as important as minimizing operational costs and reducing complexity.

-Integrating endpoint posture is important for security, but it is not as critical as minimizing operational costs and reducing complexity.
-Ensuring faster obsolescence is not a business goal. It is a technical goal that is typically achieved by using hardware and software that is based on open standards.
-Standardizing resiliency is important for reliability, but it is not as critical as minimizing operational costs and reducing complexity.

A customer investigates connectivity options for a DCI between two production data centers to aid a large-scale migration project. The migration is estimated to take 20 months to complete but might extend an additional 10 months if issues arise. All connectivity options meet the requirements to migrate workloads. Which transport technology provides the best ROI based on cost and flexibility?

  1. DWDM over dark fiber
  2. MPLS
  3. CWDM over dark fiber
  4. Metro Ethernet

Answer(s): C

Explanation:

Note the requirement, "be able to run its own varying QoS profiles without service provider interaction based on the migration stages".

Totals for each solution.

dwdm 380000
cwdm 325000
mpls 215000
metro-e 350000

At first glance MPLS is best, however QOS will need SP integration. Thus CWDM (C).



SDWAN networks capitalize the usage of broadband Internet links over traditional MPLS links to offer more cost benefits to enterprise customers. However, due to the insecure nature of the public Internet, it is mandatory to use encryption of traffic between any two SDWAN edge devices installed behind NAT gateways.

Which overlay method can provide optimal transport over unreliable underlay networks that are behind NAT gateways?

  1. DTLS
  2. TLS
  3. IPsec
  4. GRE

Answer(s): C

Explanation:

-DTLS (Datagram Transport Layer Security) is a secure transport protocol that can be used to encrypt datagrams. However, it is not as widely deployed as IPsec.
-TLS (Transport Layer Security) is a secure transport protocol that can be used to encrypt data between two hosts. However, it is not as well-suited for use over unreliable underlay networks as IPsec.
-GRE (Generic Routing Encapsulation) is a tunneling protocol that can be used to encapsulate traffic between two hosts. However, it does not provide any encryption, so it is not suitable for use over insecure underlay networks.
-IPsec (Internet Protocol Security) is a secure tunneling protocol that can be used to encapsulate traffic between two hosts. It is well-suited for use over insecure underlay networks, as it provides encryption and authentication.

Here are some additional details about IPsec:

-IPsec is a mature and widely deployed protocol.
-IPsec provides strong encryption and authentication.
-IPsec can be used to encapsulate traffic between two hosts or between two networks.

Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the design should be to monitor and keep track of any performance issues by continuously collecting and analyzing statistical information to monitor, correct, and optimize any reduced responsiveness across the network. Which layer accomplishes this design requirement?

  1. security management
  2. performance management
  3. accounting management
  4. fault management

Answer(s): B

Explanation:

-Security management is responsible for protecting the network from unauthorized access, use, disclosure, disruption, modification, or destruction.
-Accounting management is responsible for tracking and recording network usage, such as the amount of data that is transmitted and received.
-Fault management is responsible for detecting and correcting network faults.
-Performance management is responsible for monitoring and optimizing network performance.
-Therefore, the layer that accomplishes the design requirement of monitoring and keeping track of any performance issues is performance management.

Here are some additional details about performance management:

-Performance management typically involves collecting statistical information about network performance, such as throughput, latency, and availability.
-This information can be used to identify performance problems, such as bottlenecks and congestion.
-Performance management can also be used to optimize network performance, such as by adjusting traffic flows or configuring devices.
