Correct Answer: B

netstat -a is a command that displays information about active TCP connections and listening ports on a system. A network administrator can use netstat -a to check if the database engine is listening on a certain port, as well as verify if there are any connections established to or from that port.

Correct Answer: A

Correct Answer: C

An Intermediate Distribution Frame (IDF) in a secure facility typically houses networking equipment and connections. In this context, security measures are likely to involve access control to the networking infrastructure. RFID (Radio-Frequency Identification) badge readers are commonly used for secure access control in facilities. These readers can authenticate individuals based on RFID badges or cards, providing a secure means of access to network equipment.

While options A (Full-size body scanners) and B (Iris scanner) are more associated with physical security measures for access to the facility, option D (Smart deadbolt) is related to securing physical doors and may not be directly tied to securing the network infrastructure in the IDF.

Correct Answer: AE

Correct Answer: A

Traps are unsolicited messages sent by network devices to a network management system (NMS) when an event or a change in status occurs. Traps can help notify the network management team of any issues or problems on the network, such as a link failure or a device reboot. Traps can also trigger actions or alerts on the NMS, such as sending an email or logging the event. MIB stands for Management Information Base and is a database of information that can be accessed and managed by an NMS using SNMP (Simple Network Management Protocol). OID stands for Object Identifier and is a unique name that identifies a specific variable in the MIB. Baselines are measurements of normal network performance and behavior that can be used for comparison and analysis.

Correct Answer: A

The first step to troubleshoot issues with a Wi-Fi network would be to perform a site survey to gather information about the physical environment, such as signal strength and interference from other sources, which can impact network performance. Based on the results of the site survey, the placement of APs and other network components can be reviewed, channel utilization can be monitored, and cable attenuation can be tested to address the reported issues.

Correct Answer: D

SIEM stands for Security Information and Event Management, which is a tool that collects, analyzes, and correlates data from various network devices and sources to provide alerts and reports on security incidents and events. A network technician can use SIEM to correlate security events to analyze a suspected intrusion, as SIEM can help identify the source, target, method, and impact of an attack, as well as provide recommendations for remediation.

Correct Answer: A

Split-tunnel VPN configuration should be used to separate Internet and corporate traffic. This configuration only routes the corporate traffic through the VPN tunnel while allowing Internet traffic to access the Internet directly, providing a more secure connection and reducing the load on the VPN.

Correct Answer: C

In half-duplex mode, when two devices send data at the same time, a collision occurs, and both devices must wait for a random period before retransmitting the data. If the cable length is excessive, it may take longer for the collision signal to reach the far end of the cable, causing late collisions. To resolve the issue, the engineer should reduce the cable length or switch to full-duplex mode.

Correct Answer: D
