CompTIA DataSys+ Certification Exam 認定 DS0-001 試験問題 (Q118-Q123):質問 # 118
A database administrator set up a connection for a SQL Server instance for a new user, but the administrator is unable to connect using the user's workstation. Which of the following is the most likely cause of the issue?
正解：D
解説：
The most likely cause of the issue is that the SQL Server ports to the main machine are closed. SQL Server uses TCP/IP ports to communicate with clients and other servers. If these ports are blocked by a firewall or other network device, the connection will fail. The administrator should check the port configuration on both the server and the user's workstation, and make sure that they are open and match the expected values. The other options are either unlikely or unrelated to the issue. For example, the SQL Server codes performing badly or having many concurrent users may affect the performance or availability of the server, but not prevent the connection entirely; the SQL Server not being tested properly may cause errors or bugs in the functionality or security of the server, but not affect the connection unless there is a configuration problem. References: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.3 Given a scenario, troubleshoot common database deployment issues.

質問 # 119
A DBA left the company, and the DBA's account was removed from the system. Soon after, scheduled jobs began failing.
Which of the following would have most likely prevented this issue?
正解：D
解説：
The most likely way to prevent this issue is to use service accounts. Service accounts are special accounts that are used by applications or services to perform tasks or run jobs on behalf of users. Service accounts have limited permissions and access rights that are tailored to their specific functions. By using service accounts, the DBA can ensure that scheduled jobs can run independently of individual user accounts, and avoid failures due to account removal or changes. The other options are either not related or not effective for this issue. For example, load balancing is a technique that distributes the workload across multiple servers or resources to improve performance and availability; business continuity plan is a plan that outlines how an organization will continue its operations in the event of a disaster or disruption; assigning a data steward is a process that designates a person who is responsible for ensuring the quality and governance of data. References: CompTIA DataSys+ Course Outline, Domain 3.0 Database Management and Maintenance, Objective 3.3 Given a scenario, migrate data between databases.

質問 # 120
A database system crashed during a routine migration process. Which of the following should the systems administrator refer to for guidance in this situation?
正解：D
解説：
The continuity of operations policy provides guidelines and procedures for maintaining or restoring essential functions during and after disruptions like a database crash.

質問 # 121
(An analyst in the United States configured a database server so it could be accessed remotely by users in Brazil and Canada. Users in Brazil can connect to the server, but users in Canada cannot connect to the server.
Which of the following is the reason for the issue?)
正解：D
解説：
The correct answer is B. The rule set was configured to allow specific IP addresses. CompTIA DataSys+ materials emphasize the importance of network security controls, particularly firewall rules and access control lists (ACLs), in regulating remote database access. In this scenario, the database server is reachable by users in Brazil but not by users in Canada, which strongly indicates that access is being selectively permitted rather than globally blocked.
Firewall rule sets are often configured using IP-based allowlists, where only approved IP addresses or IP ranges are permitted to establish a connection. If the analyst allowed the IP address range associated with Brazil but did not include the IP range used by Canadian users, connections from Canada would fail while Brazilian users would still have access. This behavior aligns precisely with selective rule-based access control, a common best practice highlighted in DataSys+ for reducing attack surfaces.
Option A is incorrect because if the perimeter network were rejecting remote connections entirely, users in Brazil would also be unable to connect. Option C is incorrect for the same reason: a firewall rule denying all connections would block access from all locations, not just Canada. Option D, server port security being disabled, would typically prevent all inbound connections to the database service, again affecting all users regardless of geography.
CompTIA DataSys+ stresses that troubleshooting connectivity issues requires identifying whether failures are global or location-specific. Location-specific failures are most commonly caused by misconfigured firewall rules, IP filtering, or regional access restrictions. In database environments that support remote access, DBAs must ensure that firewall rules are consistently applied to all authorized networks.
Therefore, the most accurate and verified explanation is that the rule set was configured to allow specific IP addresses, and the Canadian users' IP range was not included. This makes option B the correct answer.

質問 # 122
A group of developers needs access to a database in a development environment, but the database contains sensitive dat a. Which of the following should the database administrator do before giving the developers access to the environment?
正解：A
解説：
The database administrator should mask the sensitive data before giving the developers access to the environment. Data masking is a technique that replaces sensitive data with fictitious but realistic data, such as random numbers or characters, to protect it from unauthorized access or exposure. Data masking preserves the format and structure of the original data, but does not reveal its actual value. This allows developers to work with realistic data without compromising its confidentiality or compliance. The other options are either insufficient or excessive for this scenario. For example, auditing access to tables with sensitive data may help monitor and track who accesses the data, but does not prevent it from being seen; removing sensitive data from tables may compromise the quality or completeness of the data, and may not be feasible if there is a large amount of data; encrypting connections to the development environment may protect the data in transit, but not at rest or in use. Reference: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.2 Given a scenario, implement security controls for databases.
