After a Windows reinstall, a laptop on the user's home Wi-Fi can browse the internet, but it does not appear to the family's other PCs, and the home NAS is missing from File Explorer's Network view. In Advanced sharing settings, network discovery is off for the profile the connection is currently using. What should the technician change?
- Assign the laptop a static IPv4 address on the subnet
- Set the Wi-Fi network profile type to Private
- Turn on network discovery under the Public profile

The one with the stronger signal connects without the password printed on the receipt and then opens a page asking her to sign in with her Microsoft 365 work account to get internet access. Which attack is most likely taking place?
- MAC address spoofing

After a user installed a free PDF converter, every browser on her Windows PC fails to load any website, and the Microsoft Store cannot connect either. From a command prompt, ping 8.8.8.8 succeeds and nslookup resolves names correctly. Other PCs on the same network work normally. What is the most likely cause?
- Malware configured a proxy that points to a local listener
- The DNS cache contains poisoned entries for every site
- The hosts file was edited to map every domain name to 127.0.0.1
- Windows Firewall is blocking all outbound DNS traffic
A file server is protected by a full backup every Sunday night and an incremental backup every Monday through Saturday night. The server's data disk failed on Thursday at 2:00 PM, and a replacement disk has now been installed. Which backups must be restored to return the server to its most recent backed-up state?
- Sunday's full, then the Monday, Tuesday, and Wednesday incrementals
- Sunday's full, then the Monday through Thursday incrementals
- The Wednesday incremental backup only, since it is the newest
- Sunday's full backup and the Wednesday incremental backup only
A photographer moves image files between 50 MB and 2 GB in size between a MacBook and a Windows 11 PC on an external SSD. She needs to read and write the drive on both computers without installing any extra software or drivers. Which TWO file systems should the technician consider when formatting the drive? (Select TWO)
Users report that intranet.example.com sometimes opens an old version of the site, depending on which PC they use. The technician suspects that one of the two internal DNS servers, 10.0.0.10 or 10.0.0.11, is returning an outdated address. Which command lets the technician ask the 10.0.0.11 server directly for that name, regardless of the PC's configured DNS settings?
- nslookup -querytype=A intranet.example.com
- ipconfig /displaydns
- tracert 10.0.0.11
- nslookup intranet.example.com 10.0.0.11
The Projects folder on a file server grants the Engineering group Modify, and every subfolder inherits that permission. A new subfolder, Projects\Contracts, must be accessible only to the Legal group, but the technician cannot remove Engineering from the subfolder because that permission entry is inherited. What should the technician do on the Contracts subfolder?
- Grant the Legal group Full Control on the Contracts subfolder
- Remove the Engineering group from the parent Projects folder
- Disable inheritance on it, then remove the Engineering entry
- Add a Deny Full Control entry for Everyone on the subfolder
After a malware cleanup, a PC can browse most websites, but Windows Update, the antivirus vendor's site, and several Microsoft sites fail to load. nslookup returns the correct public addresses for those sites, yet ping shows the same names resolving to 127.0.0.1. Proxy settings are empty. What should the technician do?
- Remove the malicious entries from the hosts file
- Change the PC's DNS servers to a public resolver
- Reset the browser and its proxy configuration
- Flush the DNS cache with ipconfig /flushdns
A company runs a full backup of its file server every Friday night and a differential backup every Monday through Thursday night. The server's disk fails on Thursday at noon. Which TWO backups must the technician restore to recover the most recent data? (Select TWO)

- Friday's full backup
- Wednesday's differential backup
- Thursday's differential backup
