A cloud administrator is setting up a DR site on a different zone of the same CSP. The application servers are replicated using the VM replication, and the database replication is set up using log shipping. Upon testing the DR site, the application servers are unable to access the database servers. The administrator has verified the systems are running and are accessible from the CSP portal.
Which of the following should the administrator do to fix this issue?

1. A. Change the database application IP
2. B. Create a database cluster between the primary site and the DR site
3. C. Update the connection string
4. D. Edit the DNS record at the DR site for the application servers

Correct Answer: C
A connection string is a parameter that specifies how to connect to a database server or instance. A connection string typically includes information such as the server name, database name, user name, password, and other options. Updating the connection string is the best way to fix the issue of application servers being unable to access the database servers after setting up a DR site on a different zone of the same CSP and replicating the application and database servers using VM replication and log shipping. Updating the connection string can ensure that the application servers can connect to the correct database server or instance in the DR site, as the server name or IP address may have changed after the replication.

A cloud engineer, who manages workloads in a public cloud environment, uses autoscaling to maintain availability of a critical application. During a recent burst in demands, the engineer received the following error alert:
LimitedlnstanceCapacity
Which of the following is MOST likely cause of the error?

1. A. The cloud account has a misconfigured security group.
2. B. The cloud account has exhausted the number of instances quota.
3. C. The cloud account has had rights revoked to create instances.
4. D. The autoscaling feature does not have permissions to create instances.

Correct Answer: B
A quota is a limit on the number of resources that a cloud account can create or use in a public cloud environment. If the cloud account tries to create more instances than the quota allows, it will receive a LimitedInstanceCapacity error, indicating that there is not enough available capacity to fulfill the request

A company plans to publish a new application and must conform with security standards. Which of the following types of testing are most important for the systems administrator to run to assure the security and compliance of the application before publishing? (Select two).

1. A. Regression testing
2. B. Vulnerability testing
3. C. Usability testing
4. D. Functional testing
5. E. Penetration testing
6. F. Load testing

Correct Answer: BE
Vulnerability testing and penetration testing are two types of security testing that can help to identify and mitigate potential risks in an application before publishing. Vulnerability testing is the process of scanning the application for known weaknesses or flaws that could be exploited by attackers. Penetration testing is the process of simulating real-world attacks on the application to test its defenses and find vulnerabilities that may not be detected by automated scans. Both types of testing can help to assure the security and compliance of the application by revealing and resolving any issues that could compromise the confidentiality, integrity, or availability of the application or its
data. References: CompTIA Cloud+ CV0-003 Study Guide, Chapter 5: Maintaining a Cloud Environment, page 221.

A company is switching from one cloud provider to another and needs to complete the migration as quickly as possible.
Which of the following is the MOST important consideration to ensure a seamless migration?

1. A. The cost of the environment
2. B. The I/O of the storage
3. C. Feature compatibility
4. D. Network utilization

Correct Answer: C
Feature compatibility is the degree to which the features or functionalities of a system or application are compatible or interoperable with another system or application. Feature compatibility is the most important consideration to ensure a seamless migration from one cloud provider to another, as it can affect the performance, reliability, and security of the system or application in the new cloud environment. Feature compatibility can also help complete the migration as quickly as possible, as it can reduce or eliminate the need for reconfiguration, customization, or testing of the system or application after the migration.

After a few new web servers were deployed, the storage team began receiving incidents in their queue about the web servers. The storage administrator wants to verify the incident tickets that should have gone to the web server team. Which of the following is the MOST likely cause of the issue?

1. A. Incorrect assignment group in service management
2. B. Incorrect IP address configuration
3. C. Incorrect syslog configuration on the web servers
4. D. Incorrect SNMP settings

Correct Answer: C
Incorrect syslog configuration on the web servers is the most likely cause of the issue of storage team receiving incidents in their queue about web servers after new web servers were deployed in a cloud environment. Syslog is a standard protocol that allows network devices and systems to send log messages to a centralized server or collector. Syslog can help to consolidate and manage logs from different sources in one place, which can facilitate monitoring, analysis, troubleshooting, auditing, etc. Incorrect syslog configuration on the web servers can cause them to send log messages to the wrong destination or queue, such as the storage team’s queue, rather than the web server team’s queue.
