Cloud-provided managed services

A high-usage cloud resource needs to be monitored in real time on specific events to guarantee its availability. Which of the following actions should be used to meet this requirement?

Create a dashboard with visualizations to filter the status of critical activities.

Configure a ping command to identify when the cloud instance is out of service.

Create a dashboard with visualizations to filter the status of critical activities.

Collect all the daily activity from the cloud instance and create a dump file for analysis.

Schedule an hourly scan of the network to check for the availability of the resource.

A junior cloud administrator was recently promoted to cloud administrator and has been added to the cloud administrator group. The cloud administrator group is the only one that can access the engineering VM. The new administrator unsuccessfully attempts to access the engineering VM. However, the other administrators can access it without issue. Which of the following is the best way to identify the root cause?

Reviewing the administrator's permissions to access the engineering VM

Allowing connections from 0.0.0.070 to the engineering VM

Performing a packet capture on the engineering VM

A cloud solutions architect is designing a VM-based solution that requires reducing the cost as much as possible. Which of the following solutions will best satisfy this requirement?

A critical security patch is required on a network load balancer in a public cloud. The organization has a major sales conference next week, and the Chief Executive Officer does not want any interruptions during the demonstration of an application behind the load balancer. Which of the following approaches should the cloud security engineer take?

Ask the upper management team to approve an emergency patch window.

Ask the management team to delay the conference.

Apply the security patch after the event.

Ask the upper management team to approve an emergency patch window.

Apply the security patch immediately before the conference.

A cloud engineer has provisioned a VM for a high-frequency trading application. After the VM is put into production, users report high latency in trades. The engineer checks the last six hours of VM metrics and sees the following:* CPU utilization is between 30% to 60%.* Networkln is between 50Kbps and 70Kbps.* NetworkOut is between 3.000Kpbs and 5.000Kbps.* DiskReadOps is at 30.* DiskWriteOps is at 70* Memory utilization is between 50% and 70%.Which of the following steps should the engineer take next to solve the latency issue?

Move to a network-optimized instance type as the network throughput is not enough.

Modify the disk IOPS to a higher value as the disk IO is being bottlenecked at 100 IOPS.

Increase the memory of the instance as the high-frequency trading application requires more RAM.

Increase the instance size to allocate more vCPUs as the CPU utilization is very high.

A cloud administrator learns that a major version update. 4.6.0. is available for a business-critical application.
