  A. The syslog server is down.

  B. Telnet does not work on UDP.

  C. The firewall is blocking UDP port 514

  D. The log is full on the syslog server.

• Question 144:

  A server administrator recently replaced an overheating CPU in a server at a datacenter. Following the CPU replacement, the server logs indicate the server continues to overheat. Which of the following could help mitigate this issue?

  A. The UEFI/BIOS should be updated.

  B. The CPU should be replaced with a newer model.

  C. The graphics card should be replaced.

• Question 145:

  A server technician downloaded new firmware from the manufacturer's website. The technician then attempted to install the firmware on the server, but the installation failed, stating the file is potentially corrupt.

  Which of the following should the technician have checked prior to installing the firmware?

  A. DLP configuration

  B. MBR failure

  C. ECC support

  D. MD5 checksum

  Correct Answer: D

  A MD5 checksum is a value that is calculated from a file using a cryptographic hash function. A MD5 checksum is used to verify the integrity of a file by comparing it with the original value provided by the manufacturer or the source. If the MD5 checksums match, it means that the file is authentic and has not been corrupted or tampered with. If the MD5 checksums do not match, it means that the file is potentially corrupt or malicious and should not be installed12. A DLF configuration (A) is a setting that determines how a dynamic link library (DLL) is loaded into memory and executed by an application. A DLF configuration does not check the integrity of a file. A MBR failure (B) is a problem that occurs when the master boot record (MBR) of a disk is damaged or corrupted, preventing the system from booting. A MBR failure does not check the integrity of a file. ECC support ?is a feature that enables error-correcting code (ECC) memory to detect and correct data errors in RAM. ECC support does not check the integrity of a file.

• Question 146:

  Which of the following is a system that scans outgoing email for account numbers, sensitive phrases, and other forms of PII?

  regulations, and protect the privacy of customers and employees. DLP can also block, encrypt, or quarantine emails that contain sensitive data.
