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.
Correct Answer:
C. VSANs must be routed between sites to isolate fault domains and increase overall availability.
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
Correct Answer:
B. synchronous replication over dual data centers via Metro Ethernet

design decisions? (Choose two.)
A
strategic planning approach

Correct Answer:
A. strategic planning approach
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
These are the current ping tests results between the four data centers:
A
Mumbai and Beijing
B
Cape Town and Mumbai
C
Cape Town and Beijing
D
Santiago and Mumbai
E
Santiago and Beijing
Correct Answer:
B. Cape Town and Mumbai
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?
A
DWDM over dark fiber
B
Metro Ethernet
C
MPLS wires only
D
CWDM over dark fiber
Correct Answer:
D. CWDM over dark fiber
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?
A
CWDM
B
DWDM
C
MPLS
D
Metro Ethernet
Correct Answer:
B. DWDM
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
Correct Answer:
C. . minimize operational costs
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
Correct Answer:
D. Metro Ethernet
