A rapidly growing e-commerce business with a global customer base needs a robust network design that can support their business-critical operations and ensure low-latency access for their customers around the globe. The IT team is considering different solutions to meet their requirements. Which network design is suitable for these needs?

A.

Rely on a peer-to-peer network architecture to distribute the workload among customer devices.

B.

Implement a fully on-premises network infrastructure with dedicated servers in different geographic locations.

C.

Utilize a public cloud provider to provide hosting for web servers and databases.

D.

Adopt a hybrid cloud approach, using a mix of public cloud services and private on-premises servers.

You have been asked to design a high-density wireless network for a university campus. Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)

A.

Implement a four-channel design on 2.4 GHz to increase the number of available channels

B.

Choose a high minimum data rate to reduce the duty cycle.

C.

Increases the number of SSIDs to load-balance the client traffic.

D.

Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.

E.

Enable 802.11n channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.

Which undesired effect of increasing the jitter compensation buffer is true?

A.

The overall transport jitter decreases and quality improves.

B.

The overall transport jitter increases and quality issues can occur.

C.

The overall transport delay increases and quality issues can occur.

D.

The overall transport delay decreases and quality improves.

Before migrating anything to the cloud, what are three cloud readiness assessment steps that are required to perform? (Choose three.)

A.

Determine the geolocation requirement

B.

Determine the technology obsolescence

C.

Identify the scope and business cases for migration.

D.

Assess infrastructure requirements.

E.

Evaluate available in-house resources

F.

Assess database security requirements

G.

Assess the cloud brokerage solutions

A customer migrates from a traditional Layer 2 data center network into a new SDN-based spine-and-leaf VXLAN EVPN data center within the same location. The networks are joined to enable host migration at Layer 2. Which activity should be completed each time a legacy network is migrated?

A.

The migrated VLAN should be pruned from the Layer 2 interconnects.

B.

The migrated network should have a VXLAN VNID configured within the new network.

C.

The migrated network should be advertised to the EVPN network as a Type 2 network.

D.

The migrated network should be added to the EVPN BGP routing.

Company XYZ is migrating their existing network to IPv6. Some access layer switches do not support IPv6, while core and distribution switches fully support unicast and multicast routing. The company wants to minimize cost of the migration. Which migration strategy should be used?

A.

The access layer switches must support IGMP snooping at a minimum. Any switches that do not support IGMP snooping must be replaced.

B.

Upgrade the non-supporting switches. Otherwise, it will cause an issue with the migration.

C.

Layer 2 switches will not affect the implementation of IPv6. They can be included in the design in their current state.

D.

The access layer switches must support DHCPv6. Any switches that do not support DHCPv6 must be replaced.

A centralized control plane generally means one or more controllers gather the reachability and topology information from each switching device and calculate some part of the forwarding information at some place. How can a centralized control plane be defined or described?

A.

ability to detect and react to changes remotely at each device

B.

set of processes running in a virtual or physical machine

C.

protocol running on each device

D.

set of algorithms implemented on all devices

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

A.

iBGP full mesh requirement does not dictate any specific network topology.

B.

iBGP can work only on a ring network topology with a link-state protocol like OSPF or IS-IS.

C.

iBGP full mesh requires an underlying fully meshed network topology.

D.

iBGP does not work on a ring network topology even with an underlying IGP.
