NEW QUESTION 53
A national retail company is expanding their business by adding several international sites in the next 12 months. With their current IT infrastructure, they face a high number of expenses in managing and maintaining their two current data and voice networks. In addition, the business wants to invest in technologies that offer enhancements to business activities and increase employee productivity. Which two technical requirements should be considered during the network design phase? (Choose two.)

NEW QUESTION 54
Which network management framework can be used to develop a network architecture that contains business requirements analysis, gap analysis, and network diagrams as artifacts to be used for design and implementation later?

NEW QUESTION 55
The SD-WAN architecture is composed of separate orchestration management, control, and data planes Which activity happens at the orchestration plane?

NEW QUESTION 56
Which technology is an open-source infrastructure automation tool that automates repetitive tasks for users who work in networks such as cloud provisioning and intraservice orchestration?

NEW QUESTION 57

Refer to the exhibit: A customer is migrating from a TDM-based Layer 2 VPN (L2VPN) to an MPLS Layer 3 VPN (L3VPN) in phases. The backbone OSPF connection between HUB A and HUB B will be replaced by eBGP. During the migration, some spokes (A2 and B1) are already moved to the L3VPN. The goal is to avoid routing loops during this hybrid transition.
Which design choice helps prevent routing loops during the backbone link migration?

NEW QUESTION 58
Refer to the exhibit. The network 10.10.0.0/16 has been redistributed to OSPF processes and the best path to the destination from R1 has been chosen as R1-R2-R3. A failure occurred on the link between R2 and R3, and the path was changed to R1-R4-R5-R3 What happens when the link between R2 and R3 is restored?

NEW QUESTION 59
What are three examples of solution components of the network infrastructure that help enforce security policy compliance on all devices as they seek to access the network and computing resources, thereby limiting damage from emerging security threats such as viruses worms and spyware? (Choose three.)

NEW QUESTION 60
Company XYZ is revisiting the security design for their data center because they now have a requirement to control traffic within a subnet and implement deep packet inspection. Which technology meets the updated requirements and can be incorporated into the design?

NEW QUESTION 61
Drag and drop the optical technology design characteristics on the left to the correct optical technologies on the right. Not all options are used

NEW QUESTION 62
An organization that has an on-prem data center recently underwent expansion where 5000 employees were on-boarded. The organization now needs to upgrade its network security with an ability to perform DPI and filter content based on L4 to L7 data. The network team has decided to adapt a cloud-based security service as a quick solution.
Which solution fulfills the customer requirement?

NEW QUESTION 63
Refer to the exhibit.

Traffic was equally balanced between Layer 3 links on core switches SW1 and SW2 before an introduction of the new video server in the network. This video server uses multicast to send video streams to hosts and now one of the links between core switches is over utilized Which design solution solves this issue?

NEW QUESTION 64
Refer to the exhibit.

For Company XYZ Bangkok is using ECMP to reach the 172 20 2 0/24 network The company wants a design that would allow them to forward traffic from 172 16 2 0/24 toward 172 20 2 0/24 via the Singapore router as the preferred route The rest of the traffic should continue to use ECMP Which technology fulfills this design requirement?

NEW QUESTION 65
Which two features are advantages of SD-WAN compared to MPLS-based connectivity? (Choose two.)

NEW QUESTION 66
While positive feedback loops generally don’t last long enough to bring down a network completly, then long enough to disrupt traffic flows or to cause the networkto converge more slowly then it should.
What are two examples of cases where a positive feedback loop can be long-lived and devasting to the control plane? (Choose two)

NEW QUESTION 67
Refer to the exhibit. This network is running legacy STP 802.1d. Assuming “hello_timer” is fixed to 2 seconds, which parameters can be modified to speed up convergence times after single link/node failure?

NEW QUESTION 68
Which two statements describe the usage of the IS-IS overload bit technique? (Choose two.)

NEW QUESTION 69
Drag and drop the optical technology design characteristics on the left to the correct optical technologies on the right. Not all options are used

NEW QUESTION 70
Company XYZ wants to redesign the Layer 2 part of their network and wants to use all available uplinks for increased performance. They also want to have end host reachability supporting conversational learning. However, due to design constraints, they cannot implement port-channel on the uplinks. Which other technique can be used to make sure the uplinks are in active/active state?

NEW QUESTION 71
Drag and drop the design use cases from the left onto the correct uRPF techniques used to prevent spoofing attacks Not all options are used.

NEW QUESTION 72
Refer to the exhibit.

This network is running legacy STP 802.1 d. Assuming “hello_timer” is fixed to 2 seconds, which parameters can be modified to speed up convergence times after single link/node failure?

NEW QUESTION 73
Company XYZ wants to secure the data plane of their network. Which two technologies can be included in the security design? (Choose two)

NEW QUESTION 74
An Agile for Infrastructure transition often means dismantling traditional IT hierarchies and rebuilding it to align with business objectives and workflows. Organizations are seeing the benefits of using automation tools in the network, such as faster, more efficient, more effective delivery of products and services.
