266. A data processing server uses a Linux based file system to remotely mount physical disks on a shared SAN. The server administrator reports problems related to processing of files where the file appears to be incompletely written to the disk. The network administration team has conducted a thorough review of all network infrastructure and devices and found everything running at optimal performance. Other SAN customers are unaffected. The data being processed consists of millions of small files being written to disk from a network source one file at a time. These files are then accessed by a local Java program for processing before being transferred over the network to a SELinux host for processing. Which of the following is the MOST likely cause of the processing problem?
- A.
The administrator has a PERL script running which disrupts the NIC by restarting the CRON process every 65 seconds.
- B.
The Java developers accounted for network latency only for the read portion of the processing and not the write process.
- C.
The virtual file system on the SAN is experiencing a race condition between the reads and writes of network files.
- D.
The Linux file system in use cannot write files as fast as they can be read by the Java program resulting in the errors.
Correct Answer
D. The Linux file system in use cannot write files as fast as they can be read by the Java program resulting in the errors.Explanation
The most likely cause of the processing problem is that the Linux file system being used is unable to write files as fast as they can be read by the Java program. This results in incomplete files being written to the disk. The problem is specific to this server as other SAN customers are unaffected, indicating that the issue lies with the server's file system rather than the network infrastructure. The fact that the files are being written one at a time from a network source further supports this explanation.Rate this question:

267. Company ABC was formed by combining numerous companies which all had multiple databases, web portals, and cloud data sets. Each data store had a unique set of custom developed authentication mechanisms and schemas. Which of the following approaches to combining the disparate mechanisms has the LOWEST up front development costs?
- A.
Attestation
- B.
PKI
- C.
Biometrics
- D.
Federated IDs
Correct Answer
D. Federated IDsExplanation
Federated IDs would have the lowest up front development costs in this scenario. Federated IDs allow for a centralized authentication system that can be used across multiple databases, web portals, and cloud data sets. This means that the existing custom developed authentication mechanisms and schemas can be integrated into a single federated ID system, reducing the need for extensive development and customization. This approach would be more cost-effective compared to implementing new authentication mechanisms such as Attestation, PKI, or Biometrics, which would require additional development and potentially new hardware or software implementations.Rate this question:

- A.
Device fingerprinting
- B.
Switchport analyzer
- C.
Grey box testing
- D.
Penetration testing
Correct Answer
A. Device fingerprintingExplanation
Device fingerprinting is the correct method to use in order to enumerate the ports and protocols in use by the appliance. Device fingerprinting involves analyzing the network traffic and examining the responses from the device to determine the ports and protocols being used. This method is effective in identifying the specific characteristics and behaviors of the device, allowing the security researcher to gather information about its configuration and potential vulnerabilities. It is a non-intrusive approach that can provide valuable insights into the device's security posture.Rate this question:
