After installing an OS on a new server, the administrator realizes the server does not have any network connectivity. The administrator checks the network cable, and it seems to be transferring data. Which of the following should be checked next?
A. NIC firmware
B. IPv4 options
C. DHCP options
D. Firewall options
E. DNS settings
Show Answer
Correct Answer: B
Explanation: With the physical link apparently working, check the server’s IPv4 configuration—especially its IP address, subnet mask, and default gateway. Incorrect settings can prevent network connectivity regardless of the cable connection.
Question 102
An administrator discovers a misconfiguration that impacts all servers but can be easily corrected. The administrator has a list of affected servers and a script to correct the issue. Which of the following scripting principles should the administrator use to cycle through the list of servers to deliver the needed change?
A. Linked list
B. String
C. Loop
D. Constant
Show Answer
Correct Answer: C
Explanation: A loop iterates through the list of affected servers and runs the corrective script for each one.
Question 103
A storage engineer responds to an alarm on a storage array and finds the battery on the RAID controller needs to be replaced. However, the replacement part will not be available for 14 days. The engineer needs to identify the impact of the failed battery on the system. Which of the following best describes the impact?
A. The read and write performance will be impacted.
B. The read performance will be impacted.
C. The performance will not be impacted.
D. The write performance will be impacted.
Show Answer
Correct Answer: D
Explanation: A failed RAID-controller battery typically causes the controller to disable write-back caching and use write-through mode to protect uncommitted data. This reduces write performance; read performance is generally unaffected.
Question 104
Which of the following concepts refers to prioritizing a connection that had previously worked successfully?
A. Round robin
B. SCP
C. MRU
D. Link aggregation
Show Answer
Correct Answer: C
Explanation: MRU (Most Recently Used) prioritizes the connection that was used most recently, which fits favoring a connection that previously worked successfully.
Question 105
A company is implementing a check-in desk to heighten physical security. Which of the following access controls would be the most appropriate to facilitate this implementation?
A. Security guards
B. Security cameras
C. Bollards
D. An access control vestibule
Show Answer
Correct Answer: A
Explanation: Security guards at a check-in desk can verify visitors, issue badges, notify employees, and ensure visitors sign in and are escorted. An access control vestibule controls passage through an entrance, but is not the control most directly associated with operating a check-in desk.
Question 106
A server administrator is taking advantage of all the available bandwidth of the four NICs on the server. Which of the following NIC-teaming technologies should the server administrator utilize?
A. Fail over
B. Fault tolerance
C. Load balancing
D. Link aggregation
Show Answer
Correct Answer: D
Explanation: Link aggregation combines multiple NICs into one logical link, allowing their bandwidth to be used together. Failover and fault tolerance primarily provide redundancy; load balancing distributes traffic but is not the teaming technology specifically used to aggregate link bandwidth.
Question 107
A server administrator notices the /var/log/audit/audit.log file on a Linux server is rotating too frequently. The administrator would like to decrease the number of times the log rotates without losing any of the information in the logs. Which of the following should the administrator configure?
A. Increase the audit.log file size in the appropriate configuration file.
B. Decrease the duration of the log rotate cycle for the audit.log file.
C. Remove the log rotate directive from the audit.log file configuration.
D. Move the audit.log files to a remote syslog server.
Show Answer
Correct Answer: A
Explanation: Increase the configured maximum size for audit.log (for example, auditd’s max_log_file setting). The file will take longer to reach the rotation threshold, reducing how often it rotates while retaining the logged information. Decreasing the rotation interval would make rotations more frequent.
Question 108
Which of the following BEST measures how much downtime an organization can tolerate during an unplanned outage?
A. SLA
B. BIA
C. RTO
D. MTTR
Show Answer
Correct Answer: C
Explanation: RTO (Recovery Time Objective) specifies the maximum acceptable time a service or process can remain unavailable after an outage. MTTR measures average repair/recovery time, while a BIA assesses business impacts and an SLA defines service commitments.
Question 109
Joe, a user in the IT department, cannot save changes to a sensitive file on a Linux server. An is -la shows the following listing:
-rw-r--r 1 Ann IT 6780 12 June 2019 filename
Which of the following commands would BEST enable the server technician to allow Joe to have access without granting excessive access to others?
A. chmod 777 filename
B. chown Joe filename
C. chmod g+w filename
D. chgrp IT filename
Show Answer
Correct Answer: C
Explanation: Joe belongs to the file’s IT group, so `chmod g+w filename` adds write permission for that group without granting write access to all other users. As listed, the file is already owned by group IT.
Question 110
A server administrator is installing a new server in a data center. The administrator connects the server to a midplane but does not connect any cables. Which of the following types of servers is the administrator MOST likely installing?
A. Rack
B. Virtual
C. Tower
D. Blade
Show Answer
Correct Answer: D
Explanation: Blade servers plug into a chassis and connect through its midplane, which provides power and network/data connections without requiring individual cables to be connected to the server.
