Q109. Refer to the exhibit.

ACME Mining has four data centers in Santiago. Cape Town. Mumbai, and Beijing, full-mesh connected via a 400 Mb/s EVP-LAN They want to deploy a new mission-critical application with these requirements:
cluster heartbeat 2 Mb/s continuous (250 KB/s)
cluster heartbeat one-way maximum latency 100 ms

Which hosting data center pair can host the new application?

Q110. Which two application requirements are mandatory tor traffic to receive proper treatment when placed in the priority queue? (Choose two.)

Q111. An enterprise requires MPLS connected branches to access cloud-based Microsoft 365 services over an SD-WAN solution. Internet access Is available only at dual regional hub sites that are connected to the MPLS network. Which connectivity method provides an optimum access method to the cloud-based services If one ISP suffers loss or latency?

Q112. You want to mitigate failures that are caused by STP loops that occur before UDLD detects the failure or that are caused by a device that is no longer sending BPDUs. Which mechanism do you use along with UDLD?

Q113. Various teams in different organizations within an enterprise are preparing low-level design documents to capture network parameters using a Waterfall project model:
* hardware sizing and power consumption
* Layer 2 and layer 3 services parameters
* configuration of all control plane protocols
Input from relevant stakeholders was captured at the start of the project, and the project scope has been defined based on the parameters above. What impact will it have on documentation and project deliverables if the stakeholders ask to have changes carried out in the network before the information has been captured?

Q114. Refer to the exhibit.

Q115. Company XYZ is running OSPF in their network. They have merged with another company that is running EIGRP as the routing protocol. Company XYZ now needs the two domains to talk to each other with redundancy, while maintaining a loop free environment. The solution must scale when new networks are added into the network in the near future. Which technology can be used to meet these requirements?

Q116. Refer to the exhibit.

Which impact of using three or more ABRs between the backbone area and area 1 is true?

Q117. You are tasked to design a QoS policy for a service provider so they can include it in the design of their MPLS core network If the design must support an MPLS network with six classes, and CEs will be managed by the service provider, which QoS policy should be recommended?

Q118. A network security team observes phishing attacks on a user machine from a remote location. The organization has a policy of saving confidential data on two different systems using different types of authentication. What is the next step to control such events after the security team verifies all users in Zero Trust modeling?

Q119. Refer to the exhibit.

An architect must design an enterprise WAN that connects the headquarters with 22 branch offices. The number of remote sites is expected to triple in the next three years. The final solution must comply with these requirements:
* Only the loopback address of each of the enterprise CE X and Y routers must be advertised to the interconnecting service provider cloud network.
* The transport layer must carry the VPNv4 label and VPN payload over the MP-BGP control plane.
* The transport layer must not be under service provider control.
Which enterprise WAN transport virtualization technique meets the requirements?

Q120. An enterprise organization currently provides WAN connectivity to their branch sites using MPLS technology, and the enterprise network team is considering rolling out SD-WAN services for all sites.
With regards to the deployment planning, drag and drop the actions from the left onto the corresponding steps on the right.

Q121. Which two data plane hardening techniques are true? (Choose two)

Q122. As part of workspace digitization, a large enterprise has migrated all their users to Desktop as a Sen/ice (DaaS), by hosting the backend system in their on-premises data center. Some of the branches have started to experience disconnections to the DaaS at periodic intervals, however, local users in the data center and head office do not experience this behavior. Which technology can be used to mitigate this issue?

Q123. What is a web-based model in which a third-party provider hosts applications that are available to customers over the Internet?

Q124. Company XYZ has implemented policy-based routing in their network. Which potential problem must be kept in mind about network reconvergence and PBR?

Q125. A customer has a functional requirement that states HR systems within a data center should be segmented from other systems that reside in the same data center and same VLAN. The systems run legacy applications by using hard-coded IP addresses. Which segmentation method is suitable and scalable for the customer?

Q126. 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?
