CompTIA Linux+ Certification Exam XK0-005 Prüfungsfragen mit Lösungen (Q801-Q806):

801. Frage
An administrator is troubleshooting a database service outage that was reported by a monitoring system.
Given the following output:
$ systemctl status mariadb
Oct 20 16:40:45 comptia systemd[1]: mariadb.service: Main process exited, code=killed, status=9/KILL Oct 20 16:40:45 comptia systemd[1]: mariadb.service: Failed with result 'signal'.
Oct 20 16:40:50 comptia systemd[1]: Stopped MariaDB 10.3 database server.
$ dmesg
[ 1061.491433] oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),cpuset=/,mems_allowed=0, global_oom, task_memcg=/system.slice/mariadb.service, task=mysqld,pid=1981,uid=27
[ 1061.491453] Out of memory: Killed process 1981 (mysqld) total-vm:330668kB, anon-rss:31316kB, file-rss:
OkB, shmem-rss:OkB, UID:27 pgtables:324kB oom_score_adj:0
Which of the following is the reason for the outage?

A. The administrator sent a kill signal to the database
B. The server does not have enough physical memory
C. The server is missing the DMA bus
D. The database cannot write anything else to the storage

Antwort: B

Begründung:
The oom-killer was invoked because the system ran out of memory, and as a result, it killed the mysqld process to free memory. This is a clear indication that the server did not have enough physical memory to run the MariaDB service, leading to the process being terminated.

802. Frage
A junior Linux administrator is tasked with installing an application. The installation guide states the application should only be installed in a run level 5 environment.

Which of the following commands would ensure the server is set to runlevel 5?

A. systemct1 isolate multi-user.target
B. systemct1 isolate network.target
C. systemct1 isolate graphical.target
D. systemct1 isolate basic.target

Antwort: C

Begründung:
The command that would ensure the server is set to runlevel 5 is systemct1 isolate graphical.target. This command will change the current target (or runlevel) of systemd to graphical.target, which is equivalent to runlevel 5 in SysV init systems. Graphical.target means that the system will start with a graphical user interface (GUI) and all services required for it.
The other options are not correct commands for setting the server to runlevel 5. The systemct1 isolate multi- user.target command will change the current target to multi-user.target, which is equivalent to runlevel 3 in SysV init systems. Multi-user.target means that the system will start with multiple user logins and networking, but without a GUI. The systemct1 isolate network.target command will change the current target to network.
target, which is not a real runlevel but a synchronization point for network-related services. Network.target means that network functionality should be available, but does not specify whether it should be started before or after it. The systemct1 isolate basic.target command will change the current target to basic.target, which is also not a real runlevel but a synchronization point for basic system services. Basic.target means that all essential services should be started, but does not specify whether it should be started before or after it.

803. Frage
An administrator is trying to diagnose a performance issue and is reviewing the following output:

System Properties:
CPU: 4 vCPU
Memory: 40GB
Disk maximum IOPS: 690
Disk maximum throughput: 44Mbps | 44000Kbps
Based on the above output, which of the following BEST describes the root cause?

A. The system is mostly idle, therefore the iowait is high.
B. The system has a partitioned disk, which causes the IOPS to be doubled.
C. The system has reached its maximum IOPS, causing the system to be slow.
D. The system has reached its maximum permitted throughput, therefore iowait is increasing.

Antwort: D

Begründung:
The system has reached its maximum permitted throughput, therefore iowait is increasing. The output of iostat -x shows that the device sda has an average throughput of 44.01 MB/s, which is equal to the disk maximum throughput of 44 Mbps. The output also shows that the device sda has an average iowait of
99.99%, which means that the CPU is waiting for the disk to complete the I/O requests. This indicates that the disk is the bottleneck and the system is slow due to the high iowait. The other options are incorrect because they are not supported by the outputs. The system has not reached its maximum IOPS, as the device sda has an average IOPS of 563.50, which is lower than the disk maximum IOPS of 690. The system is not mostly idle, as the output of top shows that the CPU is 100% busy. The system does not have a partitioned disk, as the output of lsblk shows that the device sda has only one partition sda1. References: CompTIA Linux+ (XK0-
005) Certification Study Guide, Chapter 17: Optimizing Linux Systems, pages 513-514.

804. Frage
A Linux systems administrator needs to copy files and directories from Server A to Server B. Which of the following commands can be used for this purpose? (Select TWO)

A. ssh
B. cp
C. rsync
D. rsyslog
E. scp
F. reposync

Antwort: C,E

Begründung:
The rsync and scp commands can be used to copy files and directories from Server A to Server B. Both commands can use SSH as a secure protocol to transfer data over the network. The rsync command can synchronize files and directories between two locations, using various options to control the copying behavior. The scp command can copy files and directories between two hosts, using similar syntax as cp. The rsyslog command is used to manage system logging, not file copying. The cp command is used to copy files and directories within a single host, not between two hosts. The reposync command is used to synchronize a remote yum repository to a local directory, not copy files and directories between two hosts. Reference: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 13: Networking Fundamentals, pages 440-441.

805. Frage
At what point is the Internal Certificate Authority (ICA) created?

A. When an administrator decides to create one.
B. During the primary Security Management Server installation process.
C. Upon creation of a certificate.
D. When an administrator initially logs into SmartConsole.

Antwort: B

Begründung:
Explanation
The Internal Certificate Authority (ICA) is created during the primary Security Management Server installation process. The ICA is a component of Check Point's Public Key Infrastructure (PKI) that issues and manages certificates for Security Gateways and administrators. The ICA is automatically installed and initialized when the primary Security Management Server is installed. The ICA is not created upon creation of a certificate, when an administrator decides to create one, or when an administrator initially logs into SmartConsole.

3: Check Point Security Management Architecture, page 32.
