Which relationship between iBGP and the underlying physical topology is true?

A European national bank considers migrating its on-premises systems to a private cloud offering in a non-European location to significantly reduce IT costs. What is a primary factor prior to migration?

Company XYZ is planning to deploy primary and secondary (disaster recovery) data center sites. Each of these sites will have redundant SAN fabrics and data protection is expected between the data center sites. The sites are 100 miles (160 km) apart and target RPO/RTO are 3 hrs and 24 hrs, respectively. Which two considerations must Company XYZ bear in mind when deploying replication in their scenario? (Choose two.)

A small organization of 20 employees is looking to deliver a network design service for modernizing customer networks to support advanced solutions.

• Project scope and weekly progress should be visualized by the management.
• Always consider feedback and make changes accordingly during the project.
• Should consider flexibility to change scope at the point of time.
  Which project methodology meets the requirements and have the least impact on the outcome?

What is the most important operational driver in building a resilient and secure modular network design?

Which three items do you recommend for control plane hardening of an infrastructure device? (Choose three.)

What is a characteristic of a secure cloud architecture model?

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

Which two technologies enable multilayer segmentation? (Choose two.)

IPFIX data collection via standalone IPFIX probes is an alternative to flow collection from routers and switches. Which use case is suitable for using IPFIX probes?

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?

An architect receives a business requirement from a CTO that states the RTO and RPO for a new system should be as close as possible to zero. Which replication method and data center technology should be used?

A multicast network is using Bidirectional PIM. Which two combined actions achieve high availability so that two RPs within the same network can act in a redundant manner? (Choose two.)

Refer to the table. A customer investigates connectivity options for a DCI between two production data centers to aid a large-scale migration project. The solution must provide a single 10G connection between locations and be able to run its own varying QoS profiles without service provider interaction based on the migration stages. All connectivity methods are at 10 Gbps. Which transport technology costs the least if the connectivity is required for just one year?

Which two features control multicast traffic in a VLAN environment? (Choose two.)

Which two mechanisms avoid suboptimal routing in a network with dynamic mutual redistribution between multiple OSPFv2 and EIGRP boundaries? (Choose two.)

Refer to the table. A customer investigates connectivity options for a DCI between two production data centers. The solution must provide dual 10G connections between locations with no single points of failure for Day 1 operations. It must also include an option to scale for up to 20 resilient connections in the second year to accommodate isolated SAN over IP and isolated dedicated replication IP circuits. All connectivity methods are duplex 10 Gbps. Which transport technology costs the least over two years in this scenario?

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?

A healthcare provider discovers that protected health information of patients was altered without patient consent. The healthcare provider is subject to HIPAA compliance and is required to protect PHI data. Which type of security safeguard should be implemented to resolve this issue?

Company XYZ wants to improve the security design of their network to include protection from reconnaissance and DoS attacks on their subinterfaces destined toward next hop routers. Which technology can be used to prevent these types of attacks?

Company XYZ is designing the network for IPv6 security and they have these design requirements:

• A switch or router must deny access to traffic from sources with addresses that are correct, but are topologically incorrect.
• Devices must block Neighbor Discovery Protocol resolutions for destination addresses that are not found in the binding table.
  Which two IPv6 security features are recommended for this company? (Choose two.)
