CMO System Configuration & Setup 3 — Questions and Answers
Question 1: A technician is configuring a Mobilyze system in a facility with multiple VLANs. What must be set on the device's network interface to allow communication across VLANs?
- A loopback address
- VLAN tagging or trunk port configuration (Correct answer)
- A static MAC address
- Duplicate IP addressing
Correct answer: VLAN tagging or trunk port configuration
VLAN tagging (802.1Q) or configuring the port as a trunk allows the Mobilyze device to communicate across multiple VLANs.
Question 2: Which encryption standard is currently recommended for securing data at rest on a Mobilyze system's storage module?
- DES (56-bit)
- 3DES (112-bit)
- AES-256 (Correct answer)
- RC4
Correct answer: AES-256
AES-256 is the industry-standard encryption algorithm recommended for securing data at rest due to its strength and performance.
Question 3: During a Mobilyze setup, the system fails to resolve hostnames. Which configuration element should the operator check first?
- Default gateway
- DNS server address (Correct answer)
- Subnet mask
- DHCP lease time
Correct answer: DNS server address
Hostname resolution failures are caused by an incorrect or missing DNS server address in the network configuration.
Question 4: What is the purpose of configuring an NTP server during Mobilyze system setup?
- To assign IP addresses automatically
- To synchronize the system clock with a reliable time source (Correct answer)
- To monitor network traffic
- To manage user authentication
Correct answer: To synchronize the system clock with a reliable time source
An NTP (Network Time Protocol) server keeps the system clock accurate, which is critical for log timestamps and certificate validation.
Question 5: A Mobilyze system is being deployed in a high-availability configuration. What feature ensures the system continues operating if one network interface fails?
- VLAN segmentation
- Network interface bonding or failover (Correct answer)
- Static routing
- MAC address filtering
Correct answer: Network interface bonding or failover
Network interface bonding or failover links multiple NICs so the system maintains connectivity if one interface fails.
Question 6: When importing a configuration profile to a new Mobilyze unit, which step should be performed AFTER the import completes?
- Delete the source configuration file
- Validate settings and restart the system (Correct answer)
- Immediately connect to the production network
- Update the firmware to the latest version
Correct answer: Validate settings and restart the system
After importing a configuration profile, validating the settings and restarting ensures the new configuration is applied correctly.
Question 7: Which log file type is most useful for diagnosing a failed Mobilyze system startup?
- Access log
- Audit trail log
- Boot or system initialization log (Correct answer)
- User activity log
Correct answer: Boot or system initialization log
Boot or system initialization logs capture events during startup, making them the most relevant source for diagnosing startup failures.
