CompTIA Server+ Certification Exam 認定 SK0-005 試験問題 (Q398-Q403):

質問 # 398
A company's IDS has identified outbound traffic from one of the web servers coming over port 389 to an outside address. This server only hosts websites. The company's SOC administrator has asked a technician to harden this server. Which of the following would be the BEST way to complete this request?

正解：B

解説：
The best way to complete the request to harden the server is to disable port 389 on the server. Port 389 is the default port used by LDAP (Lightweight Directory Access Protocol), which is a protocol that allows access and modification of directory services over a network. LDAP can be used for authentication, authorization, or information retrieval purposes. However, LDAP does not encrypt its data by default, which can expose sensitive information or credentials to attackers who can intercept or modify the network traffic. Therefore, port 389 should be disabled on a web server that only hosts websites and does not need LDAP functionality.
Alternatively, port 636 can be used instead of port 389 to enable LDAPS (LDAP over SSL/TLS), which encrypts the data using SSL/TLS certificates.


質問 # 399
Which of the following script types uses commands That start with sec-?

正解：D

解説：
Explanation
PowerShell is a scripting language and a command-line shell that uses commands that start with sec- to perform security-related tasks. For example, sec-edit is a command that edits security policies, sec-logon is a command that manages logon sessions, and sec-policy is a command that applies security templates.

質問 # 400
A Linux administrator created a script that will run at startup. After successfully writing the script, the administrator received me following output when trying to execute the script:
Bash ./startup,sh:Permission denied
Which of the following commands would BEST resolve the error message?

正解：C

解説：
This is the command that would best resolve the error message "Bash ./startup.sh: Permission denied" when trying to execute a script on Linux. Chmod is a command that changes the permissions of files or directories on Linux. +x is an option that adds the execute permission to the file or directory for the owner, group, and others. startup.sh is the name of the script file that needs to be executed. By running chmod +x startup.sh, the technician grants execute permission to the script file and allows it to be run by any user. Chmod +w startup.
sh would add write permission to the file, but not execute permission. Chmod 444 startup.sh would set read- only permission for all users, but not execute permission. Chmod 466 startup.sh would set read and write permission for the owner and write-only permission for group and others, but not execute permission.

質問 # 401
An administrator is troubleshooting a RAID issue in a failed server. The server reported a drive failure, and then it crashed and would no longer boot. There are two arrays on the failed server: a two-drive RAIO 0 set tor the OS, and an eight-drive RAID 10 set for data. Which of the following failure scenarios MOST likely occurred?

正解：C

解説：
If a server has two arrays on the failed server: a two-drive RAID 0 set for the OS, and an eight- drive RAID 10 set for data, then the most likely failure scenario that caused the server to crash and not boot is that a drive failed in the OS array. RAID 0 is a RAID configuration that stripes data across two or more drives without parity or redundancy. RAID 0 offers high performance but no fault tolerance. If one drive fails in RAID 0, all data is lost and the system cannot boot. RAID 10 is a RAID configuration that combines disk mirroring and disk striping with parity. RAID 10 offers high performance and fault tolerance. RAID 10 can tolerate up to one drive failure per mirrored pair without losing data or functionality.


質問 # 402
A software developer is unable to reach an internal website. The developer's attempt to ping the FQDN returns the following IP address: 104.18.17.32. Which of the following is the most likely reason for this result?

正解：A

解説：
Explanation
The most likely reason for this result is that there is a manual entry in the hosts file that maps the FQDN to an incorrect IP address (104.18.17.32). The hosts file is a text file that contains mappings of hostnames or domain names to IP addresses, which are used by the operating system to resolve names before querying DNS servers on the network or internet. The hosts file can be used to override DNS settings or block access to certain websites by redirecting them to different IP addresses, such as localhost (127.O.O.l) or invalid addresses (O.O.O.O). If there is a manual entry in the hosts file that conflicts with DNS records, it can cause name resolution errors or connectivity issues.
