CompTIA Linux+ Certification Exam Sample Questions (Q135-Q140):

NEW QUESTION # 135
A security analyst is monitoring the network to identify latency or slowdowns during a vulnerability scan. Which of the following functions will best achieve this?
bash
function x() {
info=$(ping -c 1 $1 | awk -F "/" 'END {print $5}')
echo "$1 | $info"
}

A. function x() { info=$(ping -c 1 $1 | awk -F "/" 'END {print $5}'); echo "$1 | $info" }
B. function x() { info=$(geoiplookup $1); echo "$1 | $info" }
C. function x() { info=$(nc -m 40 $1 | awk 'END {print $1}'); echo "$1 | $info" }
D. function x() { info=$(dig $(dig -x $1 | grep ptr | tail -n 1 | awk -F ".in-addr" '{print
$1}').origin.asn.cymru.com TXT +short); echo "$1 | $info" }

Answer: A

Explanation:
The ping command is used to measure network latency. The function provided uses ping -c 1 to ping the target once and extracts the average round-trip time using awk. This is a simple and effective way to monitor network latency during a scan or other network activity.

NEW QUESTION # 136
Which of the following BEST describes the difference between a container and a VM?

A. Containers share host OS libraries and a kernel, while VMs have their own libraries and kernel.
B. VMs are larger than containers.
C. VMs share host libraries and a kernel, while containers have their own libraries and kernel.
D. Containers are larger than VMs.

Answer: A

NEW QUESTION # 137
Some servers in an organization have been compromised. Users are unable to access to the organization's web page and other services. While reviewing the system log, a systems administrator notices messages from the kernel regarding firewall rules:

Which of the following commands will remediate and help resolve the issue?

Answer: A

Explanation:
Explanation
The command iptables -F will remediate and help resolve the issue. The issue is caused by the firewall rules that block the access to the organization's web page and other services. The output of dmesg | grep firewall shows that the kernel has dropped packets from the source IP address 192.168.1.100 to the destination port 80, which is the default port for HTTP. The command iptables -F will flush all the firewall rules and allow the traffic to pass through. This command will resolve the issue and restore the access to the web page and other services. The other options are incorrect because they either do not affect the firewall rules (ip route flush or ip addr flush) or do not exist (iptables -R).

NEW QUESTION # 138
A Linux systems administrator receives reports from various users that an application hosted on a server has stopped responding at similar times for several days in a row. The administrator logs in to the system and obtains the following output:
Output 1:

Output 2:

Output 3:

Which of the following should the administrator do to provide the BEST solution for the reported issue?

A. Configure a different nice value for the Java process to allow for more users and prevent the Java process from restarting during business hours.
B. Configure the swap space to allow for spikes in usage during peak hours and prevent the Java process from stopping due to a lack of memory.
C. Configure memory allocation policies during business hours and prevent the Java process from going into a zombie state while the server is idle.
D. Configure more CPU cores to allow for the server to allocate more processing and prevent the Java process from consuming all of the available resources.

Answer: B

Explanation:
Based on the output of the image sent by the user, the system requires more swap space to allow for spikes in usage during peak hours and prevent the Java process from stopping due to a lack of memory. The output shows that there is only 0 MB of swap space available on the system, which means that there is no room for swapping out memory pages when physical memory is full or low. The output also shows that there is only
793 MB of available memory on the system, which may not be enough to handle high-demand applications such as Java. This may cause Java to stop working due to insufficient memory or trigger an OutOfMemoryError exception. Configuring more swap space on the system would help to alleviate this issue by providing more virtual memory for applications and improving performance. Configuring memory allocation policies during business hours will not help to solve this issue, as it will not increase the amount of available memory or swap space on the system. Configuring a different nice value for Java process will not help to solve this issue, as it will only affect its scheduling priority, not its memory consumption or allocation.
Configuring more CPU cores will not help to solve this issue, as it will only increase processing power, not memory capacity or availability. References: CompTIA Linux+ (XK0-005) Certification Study Guide, Chapter 15: Managing Memory and Process Execution, page 468.

NEW QUESTION # 139
A Linux administrator has configured a Linux system to be used as a router. The administrator confirms that two network adapters are properly installed and functioning correctly. In addition, the output of the iptables -Lcommand appears to contain a complete firewall configuration.
Which of the following commands does the administrator need to issue for the router to be fully functional?

A. echo "1" > /proc/sys/net/ipv4/ip_default_ttl
B. echo "0" > /proc/sys/net/ipv4/tcp_abort_on_overflow
C. echo "0" > /proc/sys/net/ipv4/max_connections
D. echo "1" > /proc/sys/net/ipv4/ip_forward

Answer: D
