A company has just established a new branch office that needs to connect back to centrally hosted applications for day to day operations. The branch office has noted that access to many company services are slow and causing a drop in productivity. The company IT department has investigated a plan to improve performance across the link to the branch office without having to pay for more bandwidth from the Internet Service Provider. This plan includes hardware that after installation will allow for much faster access to day to day business applications. Which of the following terms BEST describes the action taken by the IT department?

A. LAN optimization

B. WAN optimization

C. Load balancing

D. Bandwidth compression

Network statistics show that the 1Gbps switch port used for storage traffic is fully saturated. Which of the following switch technologies can be used to provide twice the bandwidth?

A. NAT

B. Multipathing

C. Link aggregation

D. VLAN

While reviewing the auto-scaling events for a web application, a cloud engineer identified that the application upsized and downsized multiple times within the last hour. Which of the following should the cloud engineer do NEXT?

A. Add more systems into the scaling group.

B. Review the load balancer configuration settings.

C. Review auto-scaling policies to detect a misconfiguration.

D. Monitor auto-scaling events for the next 24 hours.

An administrator is performing a migration of a physical cluster that uses boot from SAN into private cloud. The systems administrator needs to minimize the downtime required.

Which of the following migrations is the BEST option for the systems administrator to use?

A. P2V with cold system cloning on the storage infrastructure.

B. P2V with storage migration on the hypervisor.

C. P2V with copy of the LUNs into data stores for hypervisor access.

D. P2V with raw device mapping/pass-through LUNs on the storage system.

A cloud architect is deploying a VM in a public IaaS cloud. The software that will be installed on the VM is not compatible with any of the OS versions in the system images offered by the IaaS vendor. Which of the following is the BEST way to deploy a VM with the required OS?

A. Develop a VM image on an on-premises hypervisor and send it on a physical hard drive to the cloud provider's datacenter.

B. Use a bare metal service instead of IaaS and verify that the bring-your-own OS feature is available.

C. Develop a VM image on an on-premises hypervisor and upload it to the cloud via API.

D. Host the server on premises and integrate it with the IaaS service using the hybrid cloud model.

A company has a requirement of an active/active datacenter and wants to implement synchronous replication for all its storage services. The company is doing a proof of concept with a datacenter provider that has two datacenters 200mi

(322km) apart that utilize MPLS. Each time the company starts synchronous replication, it fails. All network connectivity has been established and is functioning correctly.

Which of the following is the MOST likely cause?

A. Latency between datacenters

B. Applications are latency tolerant

C. Link bandwidth between datacenters

D. Link between datacenters is not fiber

A CSA needs to apply new OS security patches to the application cluster server farm in a public cloud provider.

A. Update and validate the runbook procedures prior to the patch rollout.

B. Leverage the infrastructure as code and replace each server farm member.

C. Configure and patch each server individually and take an OS differential backup.

D. Snapshot all existing server farm members before installing the patch.
