Question 1
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. Target RPO/RTO requirements cannot be met due to the one-way delay introduced by the distance between sites.
B. VSANs must be extended from the primary to the secondary site to improve performance and availability.
C. VSANs must be routed between sites to isolate fault domains and increase overall availability.
D. Synchronous data replication must be used to meet the business requirements.
E. Asynchronous data replication should be used in this scenario to avoid performance impact in the primary site.
Question 2
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. synchronous replication over geographically dispersed dual data centers via MPLS
B. synchronous replication over dual data centers via Metro Ethernet
C. asynchronous replication over geographically dispersed dual data centers via CWDM
D. asynchronous replication over dual data centers via DWDM
Question 3
What are two primary design constraints when a robust infrastructure solution is created? (Choose two.)
A. component availability
B. monitoring capabilities
C. project time frame
D. staff experience
E. total cost
Question 4
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?
A. FCAPS
B. Cobit
C. TOGAF
D. ITIL
Question 5
Which two types of planning approaches are used to develop business-driven network designs and to facilitate the design decisions? (Choose two.)
A. strategic planning approach
B. business optimization approach
C. tactical planning approach
D. modular approach
E. cost optimization approach
Question 6
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 msThese are the current ping tests results between the four data centers:Which hosting data center pair can host the new application?
A. Mumbai and Beijing
B. Cape Town and Mumbai
C. Cape Town and Beijing
D. Santiago and Mumbai
E. Santiago and Beijing
F. Santiago and Cape Town
Question 7
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 __cpLocations 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?
A. DWDM over dark fiber
B. Metro Ethernet
C. MPLS wires only
D. CWDM over dark fiber
Question 8
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 __cpLocations 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?
A. CWDM
B. DWDM
C. MPLS
D. Metro Ethernet
Question 9
What are two examples of business goals to be considered when a network design is built? (Choose two.)
A. integrate endpoint posture
B. ensure faster obsolescence
C. minimize operational costs
D. reduce complexity
E. standardize resiliency
Question 10
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 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?
A. DWDM over dark fiber
B. MPLS
C. CWDM over dark fiber
D. Metro Ethernet
