Sample Questions
Practice all 10 →A company's IT department follows a strict change management process. A technician is implementing a planned change to update the firmware on a network switch. The change has been approved and the maintenance window has started. During the firmware update, the switch loses power due to a circuit breaker tripping. The technician has a backup configuration file. According to best practices, what should the technician do FIRST?
Explanation: When a planned change fails during implementation, especially due to an unexpected event like a power loss during a firmware update, the immediate priority is to follow the backout plan to restore the system to its previous known-good state. A firmware update interrupted by power loss can leave the device in a corrupt or non-functional state. The backout plan should include steps to recover the previous firmware version. Documenting the incident and notifying the change advisory board (CAB) are important but should occur after the immediate threat is contained. Attempting to resume the update or simply rebooting could worsen the situation.
A technician copies a missing 32-bit DLL file into C:\Windows\System32 on a 64-bit Windows 10 system and registers it with regsvr32. The 32-bit application still fails with a missing DLL error. What is the MOST likely reason?
Explanation: On a 64-bit Windows system, the System32 folder is reserved for 64-bit system files. 32-bit DLLs should be placed in the SysWOW64 folder, which is the 32-bit system directory. By placing the 32-bit DLL in System32, the 32-bit application does not see it because the file system redirects 32-bit application file access from System32 to SysWOW64. The technician should copy the DLL to C:\Windows\SysWOW64 and register it using the 32-bit version of regsvr32 located in SysWOW64.
A user is unable to connect to any network shares from a Windows 10 computer. Other computers on the same network can access the shares. The technician confirms the computer has an IP address and can ping other devices. Which Windows feature should the technician check first?
Explanation: Network discovery and file sharing must be enabled for a Windows computer to browse and connect to network shares. Firewall rules might block file sharing, but since pinging works, it is less likely. Network adapter driver issues would affect all network activity. Windows Update status is not directly related to file sharing.
A user has a Windows 10 computer that is not joined to the corporate domain. The user needs to frequently access shared folders on a file server that requires domain credentials. Which Windows tool allows the user to securely store these domain credentials so they can be automatically used when mapping network drives?
Explanation: Credential Manager stores usernames and passwords for resources such as network shares, servers, or websites. By adding the domain credentials once, the user can map drives and access resources without re-entering credentials each time.
A user receives an email that appears to be from a well-known shipping company, asking them to download an invoice attachment. The attachment contains a macro-enabled Word document. What type of malware is most likely being delivered?
Explanation: Macro-enabled documents delivered as email attachments often deliver Trojans, which disguise themselves as legitimate files. Ransomware encrypts files after execution, worms self-replicate without user action, and rootkits hide deep in the system. The correct answer is Trojan because the macro is a delivery mechanism for a payload that may install additional malware.
