After deploying multiple copies of database servers, data scrambling is started on them to anonymize user data. A few minutes later, the systems administrator receives multiple complaints regarding the performance of other VMs. CPU and memory have been eliminated as possible bottlenecks. Which of the following should be verified NEXT as a possible bottleneck?
- Storage array

A cloud administrator is configuring a bastion host. The bastion host will be used to administer systems in the cloud remotely from the administrator’s on-premises desktop. The administrator is given the following requirements:
Ensure port 22 is open on the host and only allow the public IP of the on-premises router/firewall.
Ensure port 3389 is open on the host and only allow the public IP of the on-premises router/firewall.
Harden these services with PKI (where applicable).
Given this scenario, which of the following should the administrator utilize to BEST address these requirements? (Select THREE).
- RDP protocol from the desktop to the bastion host
- Telnet protocol from the desktop to the bastion host
- SSH protocol from the desktop to the bastion host
- MD5 and RC4 with a signed certificate
- RSA and AES with a signed certificate
- Blowfish and SHA-1 with a signed certificate
- VNC protocol from the desktop to the bastion host
After scheduled network maintenance, users report that an externally hosted web application is particularly slow to load. Small items on the page load such as text documents and markup, but larger multimedia files do not load. Which of the following is the MOST likely cause of the reported issues?
- Incorrect MTU in the network segment
- Misconfiguration of QoS settings
- Incorrect VLAN for the affected PCs
- Excessive latency on the local LAN segment
A cloud administrator for a state government agency is tasked with giving access to the voter registration application to a government agency in another state. Only authorized officials from each state should access the application. These agencies have a common environment where applications have been deployed in the past. Which of the following should the cloud administrator do to give access to the application?
- Deploy part of the application into a public cloud and establish secure connections to a private cloud environment.
- Deploy the application to a community cloud that is shared with multiple state government agencies only.
- Deploy the application to a public cloud and implement ACLs and security access policies to limit access.
- Deploy the application to the state’s private cloud and give authentication credentials to the other state’s authorized officials.
A software solution must be deployed based on the most granular access level. Which of the following methods should be used to meet the requirements?
Worldwide users from an organization are experiencing intermittent access to a global cloud application. The cloud provider availability dashboard shows all resource availability has been 100% in the last two weeks. No network outages have been reported. Which of the following should the organization’s administrator do BEFORE calling the cloud provider?
- Check the firewall rules on the headquarters site.
- Restart the application and applicable services.
- Allow all traffic at the cloud provider side from any private IP address.
- Evaluate the DNS to ensure all configurations are correct.
A cloud deployment engineer is modifying versions of the existing template image to instantiate new VMs. The engineer accomplishes this through the cloud self-service portal. After the version is changed and a new VM is successfully started, it does not have any connectivity, and all ping tests to other VMs fail. Which of the following would be the BEST approach to solve the problem?
- Start the console session to the VM; check network static routes; test the ping to default gateway and next hop; and reconfigure the gateway IP.
- Delete the VM; create a new flavor; turn on network service; add the new image to the template manager; and reinstantiate the VM using this new image.
- Delete the VM; check the IP assignment and planning; modify configuration in the deployment template; and instantiate the VM again using the new template.
- Assign new IPs to the newly created VMs by changing and running the deployment template; and check the connectivity on the cloud self-service portal afterward.
A cloud provider is evaluating an insider threat. A resource from the company operations team has access to the servers’ virtual disks. This poses a risk that someone could copy and move the virtual server image and have access to the data. Which of the following solutions would help mitigate this problem?
- Virtual firewall
After monthly patching, a large number of users who are logged onto the network report that application links from a company’s intranet site, which previously opened directly into the website, are now prompting for logon information. Application administrators confirm that the websites in question are working properly. Which of the following is the MOST likely cause of the new behavior?
- SSO issues
- Password expiration
- Account lockout
- Certificate expiration
A cloud administrator is analyzing usage trends for a website housed within an IaaS cloud platform. The administrator notices that traffic and visitors to the site quadrupled from the normal baseline during the holiday season. The environment has a load balancer that uses standardized VMs to host the applications. Given this scenario, which of the following would be the MOST efficient, provide no downtime, and address the temporary spike in traffic?
- Implement an upward vertical scaling solution.
- Implement a downward vertical scaling solution.
- Implement an inward horizontal scaling solution.
- Implement an outward horizontal scaling solution.
A company is implementing a launchpad within an existing application that will point to an existing SaaS provider. One of the requirements is the user should not have to log on multiple times. SSO is in place. When the launchpad is used, the user is redirected to SaaS providers as designed, but is asked for login credentials. Which of the following is the MOST likely cause of this issue?
- Users do not exist within the SaaS provider.
- Group permissions are incorrect.
- Users do not exist in directory services.
- The federation is failing.
A cloud service administrator is consuming PaaS services and is performing baseline configuration tests. Which of the following is part of the PaaS consumer’s responsibility with respect to the baseline confirmation tests?

An engineer is configuring the monitoring for a new application server. During the day, the CPU on the server is baselined at approximately 30% utilization. At midnight, a batch job is scheduled to run that will drive the CPU utilization up to 75% for approximately an hour. Any time the CPU utilization is at 40% or higher for longer than ten minutes, administrators will receive an alert. Which of the following is the BEST method to ensure administrators do not experience message fatigue due to false alerts?
- Set a different threshold during the batch peak time.
- Increase the alert time threshold to 65 minutes.
- Increase the alert utilization threshold to 80%.
- Manually disable monitoring during the batch job.
A cloud administrator configures a new web server for the site https://companyname.com. The administrator installs a wildcard SSL certificate for *.companyname.com. When users attempt to access the site, a certificate error is received. Which of the following is the MOST likely cause of the error?
