NEW QUESTION # 141
A newly hired Linux administrator needs to grant access to the Linux servers by generating a password-protected RSA key of 4096 bytes. Which of the following commands will accomplish this task?
Answer: C
Explanation:
The ssh-keygencommand is used to generate SSH key pairs.
To generate an RSA key with a length of 4096 bits, the correct syntax is:
* -t rsa: Specifies the type of key to generate, which is RSA.
* -b 4096: Specifies the number of bits for the key, in this case 4096.
By running this command, the user will be prompted to enter a passphrase to password-protect the key, which satisfies the requirement for generating a password-protected RSA key of 4096 bits.
NEW QUESTION # 142
A systems administrator needs to set the IP address of a new DNS server. Which of the following files should the administrator modify to complete this task?
Answer: D
Explanation:
DNS client configuration is a foundational Linux networking task covered in Linux+ V8 system management objectives. When an administrator needs to specify the IP address of a DNS server that the system should use for name resolution, the correct file to modify is /etc/resolv.conf.
The /etc/resolv.conf file defines DNS resolver settings, including one or more nameserver entries that specify the IP addresses of DNS servers. Applications and system services rely on this file to resolve hostnames to IP addresses.
The other options are incorrect. /etc/whois.conf configures WHOIS queries. /etc/nsswitch.conf controls the order of name resolution sources but does not define DNS server IP addresses. /etc/dnsmasq.conf configures a local DNS caching service, not the system-wide resolver directly.
Linux+ V8 documentation highlights /etc/resolv.conf as the authoritative DNS client configuration file, though it may be dynamically managed by tools such as NetworkManager or systemd-resolved.
Therefore, the correct answer is B. /etc/resolv.conf.
NEW QUESTION # 143
Which of the following describes PEP 8?
Answer: B
Explanation:
PEP 8 is the official Python Enhancement Proposal that provides coding style guidelines for writing clean, consistent, and readable Python code.
NEW QUESTION # 144
Application owners are reporting that their application stops responding after several days of running, and they need to restart it. A Linux administrator obtains the following details from the dmesgcommand:
The application owners mentioned that resources to the system have boon increased, and the error takes longer to appear. Which of the following best describes the reason the process is being terminated by OOM?
Answer: A
Explanation:
The OOM killer is terminating the application after it runs for several days, and adding system resources only delays the failure. That behavior indicates the application is gradually consuming more memory over time, which is consistent with a memory leak.
NEW QUESTION # 145
A Linux administrator updates the DNS record for the company using:
cat /etc/bind/db.abc.com
The revised partial zone file is as follows:
ns1 IN A 192.168.40.251
ns2 IN A 192.168.40.252
www IN A 192.168.30.30
When the administrator attempts to resolve www.abc.com to its IP address, the domain name still points to its old IP mapping:
nslookup www.abc.com
Server: 192.168.40.251
Address: 192.168.40.251#53
Non-authoritative answer:
Name: www.abc.com
Address: 199.168.20.81
Which of the following should the administrator execute to retrieve the updated IP mapping?
Answer: A
Explanation:
This scenario represents a classic DNS troubleshooting situation covered in the Troubleshooting domain of the CompTIA Linux+ V8 objectives. Although the DNS zone file has been updated correctly on the BIND server, the system continues to resolve the domain name to an outdated IP address. This behavior strongly indicates DNS caching rather than a configuration error in the zone file itself.
Modern Linux systems that use systemd-resolved cache DNS responses locally to improve performance and reduce external queries. Even after a DNS record is updated on the authoritative server, cached results may persist until the cache expires or is manually cleared. The nslookup output showing a non-authoritative answer further confirms that the response is being served from a cache rather than directly from the updated zone data.
The correct solution is to flush the local DNS cache so the system can retrieve the updated record from the DNS server. The command resolvectl flush-caches clears all cached DNS entries maintained by systemd- resolved, forcing fresh queries to authoritative name servers. This aligns directly with Linux+ V8 documentation for resolving name resolution inconsistencies caused by stale cache entries.
The other options are incorrect for the following reasons. systemd-resolve query www.abc.com performs a DNS lookup but does not clear cached entries. systemd-resolve status only displays resolver configuration and statistics. service nslcd reload reloads the Name Service LDAP daemon and is unrelated to DNS resolution or caching.
Linux+ V8 emphasizes identifying whether issues originate from services, configuration, or cached data. In this case, flushing the DNS cache is the correct and least disruptive corrective action.
Therefore, the correct answer is D. resolvectl flush-caches.
