A. Implement web servers in both continents and set up a VPN between the VPCs.
B. Implement web servers on both continents and peer the VPCs.
C. Implement a CDN and offload the images to an object storage.
D. Implement a replica of the entire solution on every continent.
C. Implement a CDN and offload the images to an object storage.
Once a year, a company’s private cloud experiences increased activity. The company has a disaster recovery site that is hosted in a public cloud. To avoid investment in additional hardware, which of the following actions would BEST address this issue?
A. Configure cloud bursting to spin up new VMs automatically and terminate them when usage is back to normal.
B. Activate the disaster recovery site, and deactivate it when usage is back to normal.
C. Create a new backup site and decommission it when usage is back to normal.
D. Manually add memory and CPU to existing VMs, and remove them when usage is back to normal.
B. Activate the disaster recovery site, and deactivate it when usage is back to normal.
A systems administrator is troubleshooting issues with network slowness. Traffic analysis shows that uplink bandwidth on the core switch is often sustained at
125Mbps due to a
combination of production traffic from other sources. Which of the following would BEST resolve the issue?
A. Turn off the servers that use the most bandwidth.
B. Enable QoS to prioritize production traffic.
C. Increase the buffer size on the core switch.
D. Reboot the core switch.
C. Increase the buffer size on the core switch.
An enterprise recently upgraded the memory of its on-premises VMs from 8GB to 16GB. However, users are not experiencing any performance benefit. Which of the following is the MOST likely reason?
A. Insufficient memory on the hypervisor
B. Operating system memory limit
C. Memory mismatch error
D. Dynamic memory allocation
A. Insufficient memory on the hypervisor
A systems administrator is deploying a new virtualized environment. The setup is a three-server cluster with 12 VMs running on each server. While executing a vertical-scaling test of the vCPU on the VMs, the administrator gets an error. Which of the following issues is MOST likely occurring?
A. Compute
B. Storage
C. Licensing
D. Scripts
C. Licensing
A company would like to migrate its current on-premises workloads to the public cloud. The current platform requires at least 80 instances running at all times to work properly. The company wants the workload to be highly available, even if the cloud provider loses one region due to a catastrophe, and the costs to be kept to a minimum. Which of the following strategies should the company implement?
A. Create /25 subnets in two regions and run 80 instances on each one.
B. Create /26 subnets in two regions and run 40 instances on each one.
C. Create /26 subnets in three regions and run 40 instances on each one.
D. Create /26 subnets in three regions and run 80 instances on each one.
A. Create /25 subnets in two regions and run 80 instances on each one.
A web application has been configured to use auto-scaling for provisioning and deprovisioning more VMs according to the workload. The systems administrator deployed a new Cl/CD tool to automate new releases of the web application. During the night, a script was deployed and configured to be executed by the VMs during bootstrapping. Now, the auto-scaling configuration is creating a new VM every five minutes. Which of the following actions will MOST likely resolve the issue?
A. Reducing the maximum threshold in the auto-scaling configuration
B. Debugging the script and redeploying it
C. Changing the automation tool because it is incompatible
D. Modifying the script to shut down the VM after five minutes
B. Debugging the script and redeploying it.
A systems administrator is troubleshooting an application that is configured to auto-scale with a minimum of two nodes and a maximum of four. The application will scale out if the CPU utilization of one of the nodes exceeds 80% for more than five minutes and will scale in if the CPU utilization of one of the nodes drops under
20% for more than ten minutes. There is a reverse proxy in front of the application. The systems administrator notices two of the nodes are often running over 80% for a long period of time, which is triggering the creation of the other two nodes; however, they are being created and terminated while the load in the first two remains over 50% all the time. Which of the following should the administrator configure to fix this issue?
A. Disable DNS caching in the reverse proxy.
B. Reduce the minimum node count to one.
C. Disable TLS tickets.
D. Reduce the scale-out rule to 50%.
E. Increase the scale-in rule to 50%.
A. Disable DNS caching in the reverse proxy.
Over the last couple of years, the growth of a company has required a more complex DNS and DHCP environment. Which of the following should a systems administration team implement as an appropriate solution to simplify management?
A. IPAM
B. DoH
C. VLAN
D. SDN
A. IPAM
A financial industry services firm was the victim of an internal data breach, and the perpetrator was a member of the company’s development team. During the investigation. one of the security administrators accidentally deleted the perpetrator’s user data. Even though the data is recoverable, which of the following has been violated?
A. Chain of custody
B. Evidence acquisition
C. Containment
D. Root cause analysis
A. Chain of custody
