SIMULATION

You are a cloud engineer working for a cloud service provider that is responsible for an IaaS offering.

Your customer, who creates VMs and manages virtual storage, has noticed I/O bandwidth issues and low IOPS (under 9000).

Your manager wants you to verify the proper storage configuration as dictated by your service level agreement (SLA).

The SLA specifies:

1.

Each SFP on the hypervisor host must be set to the maximum link speed allowed by the SAN array. . All SAN array disk groups must be configured in a RAID 5.

2.

The SAN array must be fully configured for redundant fabric paths. . IOPS should not fall below 14000 INSTRUCTIONS Click on each service processor to review the displayed information. Then click on the drop-down menus to change the settings of each device as necessary to conform to the SLA requirements.

A. See the explanation for complete solution.

B. PlaceHolder

C. PlaceHolder

D. PlaceHolder

HOTSPOT

The QA team is testing a newly implemented clinical trial management (CTM) SaaS application that uses a business intelligence application for reporting. The UAT users were instructed to use HTTP and HTTPS.

Refer to the application dataflow:

1.

1A -The end user accesses the application through a web browser to enter and view clinical data.

2.

2A -The CTM application server reads/writes data to/from the database server.

3.

1B -The end user accesses the application through a web browser to run reports on clinical data.

4.

2B -The CTM application server makes a SOAP call on a non-privileged port to the BI application server.

5.

3B -The BI application server gets the data from the database server and presents it to the CTM application server.

When UAT users try to access the application using https://ctm.app.com or http://ctm.app.com, they get a message stating: "Browser cannot display the webpage." The QA team has raised a ticket to troubleshoot the issue.

INSTRUCTIONS

You are a cloud engineer who is tasked with reviewing the firewall rules as well as virtual network settings.

You should ensure the firewall rules are allowing only the traffic based on the dataflow.

You have already verified the external DNS resolution and NAT are working.

Verify and appropriately configure the VLAN assignments and ACLs. Drag and drop the appropriate VLANs to each tier from the VLAN Tags table. Click on each Firewall to change ACLs as needed.
