A server administrator is completing an OS installation for a new server. The administrator patches the server with the latest vendor-suggested software, configures DHCP, and verifies all network cables are properly connected in the IDF, but there is no network connectivity. Which of the following is the MOST likely reason for the lack of connectivity?
Correct Answer:
A
If the server administrator patches the server with the latest vendor- suggested software, configures DHCP, and verifies all network cables are properly connected in the IDF, but there is no network connectivity, then the most likely reason for the lack of connectivity is that the VLAN is improperly configured. A VLAN (Virtual Local Area Network) is a logical grouping of network devices that share the same broadcast domain and can communicate with each other without routing. If the server is assigned to a different VLAN than the DHCP server or the default gateway, itwill not be able to obtain an IP address or reach other network devices. The DNS configuration is not relevant for network connectivity, as DNS only resolves names to IP addresses. The OS version is not likely to be incompatible with the network switch vendor, as most network switches use standard protocols and interfaces. The HIDS (Host-based Intrusion Detection System) is not likely to prevent the connection, as HIDS only monitors and alerts on suspicious activities on the host.

A human resources analyst is attempting to email the records for new employees to an outside payroll company. Each time the analyst sends an email containing employee records, the email is rejected with an error message. Other emails outside the company are sent correctly. Which of the following is MOST likely generating the error?
Correct Answer:
C
DLP (Data Loss Prevention) software is a type of security software that monitors and controls the transfer of sensitive or confidential data outside the organization. DLP software can prevent data breaches, data leaks, or data theftby blocking, encrypting, or alerting on unauthorized data transfers. DLP software can be applied to various channels, such as email, web, cloud, or removable devices.
In this scenario, the human resources analyst is attempting to email the records for new employees to an outside payroll company. The records for new employees may contain sensitive or confidential data, such as personal information, tax information, or bank account information. The DLP software may detect this data and block the email from being sent outside the company, as it may violate the company’s data protection policy or regulations. The DLP software may also generate an error message to inform the analyst of the reason for the rejection.
A server administrator has received calls regarding latency and performance issues with a file server. After reviewing all logs and server features the administrator discovers the server came with four Ethernet ports, out only one port is currently in use. Which of the following features will enable the use of all available ports using a single IP address?
Correct Answer:
D
NIC teaming is a feature that allows the use of multiple network interface cards (NICs) as a single logical interface with a single IP address. It can improve the network performance, bandwidth, and redundancy of a server. Verified References: [NIC teaming], [Network interface card]
A server administrator is experiencing difficulty configuring MySQL on a Linux server. The administrator issues the getenforce command and receives the following output:
># Enforcing
Which of the following commands should the administrator issue to configure MySQL successfully?
Correct Answer:
A
The command that the administrator should issue to configure MySQL successfully is setenforce 0. This command sets the SELinux (Security-Enhanced Linux) mode to permissive, which means that SELinux will not enforce its security policies and will only log any violations. SELinux is a feature that provides mandatory access control (MAC) for Linux systems, which can enhance the security and prevent unauthorized access or modification of files and processes. However, SELinux can also interfere with some applications or services that require specific permissions or ports that are not allowed by SELinux by default. In this case, MySQL may not be able to run properly due to SELinux restrictions. To resolve this issue, the administrator can either disable SELinux temporarily by using setenforce 0, or permanently by editing the /etc/selinux/config file and setting SELINUX=disabled. Alternatively, the administrator can configure SELinux to allow MySQL
to run by using commands such as semanage or setsebool.

Which of the following is a system that scans outgoing email for account numbers, sensitive phrases, and other forms of Pll?
Correct Answer:
B
DLP stands for Data Loss Prevention and it is a system that scans outgoing email for account numbers, sensitive phrases, and other forms of PII (Personally Identifiable Information). DLP can help prevent data breaches, comply with regulations, and protect the privacy of customers and employees. DLP can also block, encrypt, or quarantine emails that contain sensitive data.References: https://www.comptia.org/training/resources/exam-objectives/comptia-server-sk0-005-exam- objectives (Objective 3.2)
