At startup, a workstation displays a S.M.A.R.T. warning that the hard drive’s reallocated sector count has increased sharply. The drive still boots and the user’s files open normally. What should the technician do FIRST?

Why that one is wrong. The drive may fail before next month. The data should be protected now.

Why that one is wrong. Silencing the warning ignores a reliable predictor of failure and leaves the data at risk.

Why that one is wrong. Defragmenting adds heavy read and write activity to a failing drive and does not repair it. It risks losing data before a backup exists.

Why C is right. A rising reallocated sector count predicts drive failure. Protect the data while the drive still works, then replace it.

A S.M.A.R.T. warning is advance notice of failure: back up first, then replace the drive.

A few more sample questions

Sample question 1. An office is replacing monitors and wants to keep only video interfaces that carry a purely digital signal, so no analog conversion happens anywhere along the path. Which two interfaces meet that requirement? (Choose two.)

  1. VGA
  2. HDMI
  3. DVI-A
  4. Composite video
  5. DisplayPort

Sample question 2. An old storage appliance only supports file sharing over NetBIOS over TCP/IP; it cannot use direct-hosted SMB. A new firewall between the office and the appliance allows TCP 445, and browsing by NetBIOS name already works, but file sessions fail. Which additional port must be allowed?

  1. UDP 137, the NetBIOS name service
  2. TCP 139, the NetBIOS session service
  3. UDP 138, the NetBIOS datagram service
  4. TCP 135, the RPC endpoint mapper service

Sample question 3. Inside a concrete office building, a user’s phone shows one bar of cellular service and her calls keep dropping, but the office Wi-Fi signal is strong. Her carrier supports voice calls over Wi-Fi. What should the technician configure?

  1. Turn on Personal Hotspot so the phone can share its single bar of signal
  2. Enable Wi-Fi Calling in cellular settings so calls use Wi-Fi
  3. Install a VPN app, because encrypting the traffic strengthens the connection
  4. Turn on data roaming so the phone can find a stronger partner network
