Question #6 (Topic: Single Topic)

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:

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

Answer: B

Question #7 (Topic: Single Topic)

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

Answer: D

Question #8 (Topic: Single Topic)

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

Answer: B

Question #9 (Topic: Single Topic)

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

Answer: CD

Question #10 (Topic: Single Topic)

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

Answer: D
