A network technician is deploying a new machine in a small branch office that does not have a DHCP server.
The new machine automatically receives the IP address of 169.254.0.2 and is unable to communicate with the rest of the network. Which of the following would restore communication?
A. Static entry
B. ARP table
C. APIPA address
D. NTP specification
正解：A
解説：
Explanation
A static entry is the best option to restore communication for the new machine in a small branch office that does not have a DHCP server. A static entry means manually configuring the IP address, subnet mask, default gateway, and DNS server for the network adapter of the machine. A static entry ensures that the machine has a valid and unique IP address that matches the network configuration and can communicate with the rest of the network.
The new machine automatically receives the IP address of 169.254.0.2 because it uses APIPA (Automatic Private IP Addressing), which is a feature that enables computers to self-assign an IP address when a DHCP server is not available. However, APIPA only works for local communication within the same subnet, and does not provide a default gateway or a DNS server. Therefore, the new machine is unable to communicate with the rest of the network, which may be on a different subnet or require a gateway or a DNS server to access.
The other options are not related to restoring communication for the new machine. ARP table is a cache that stores the mapping between IP addresses and MAC addresses for the devices on the network. NTP specification is a protocol that synchronizes the clocks of the devices on the network.

A company downloads a large number of files over the internet daily. The company needs a way to ensure the files have not been modified or corrupted during the download process. Which of the following should the company do to verify the files?
A. Clear browsing data
B. Use trusted sources
C. Check the hash value
D. Install SSL certificates
正解：C
解説：
Comprehensive and Detailed In-Depth
Checking the hash value (such as MD5, SHA-1, or SHA-256) is the best way to verify file integrity after downloading. A hash function generates a unique string for a file. If even a single bit in the file is changed, the hash value will be different. Many software vendors provide hash values (checksums) on their websites to help users confirm that the files were downloaded without corruption or tampering.
A . Clear browsing data - Incorrect. Clearing browsing data does not affect downloaded files or their integrity.
B . Install SSL certificates - Incorrect. SSL certificates encrypt data transmission but do not verify the integrity of downloaded files.
D . Use trusted sources - While downloading files from trusted sources reduces the risk of corruption, it does not verify file integrity.

A user receives the following error while attempting to boot a computer.
BOOTMGR is missing
press Ctrl+Alt+Del to restart
Which of the following should a desktop engineer attempt FIRST to address this issue?
A. Reimage the workstation.
B. Roll back the updates.
C. Partition the hard disk.
D. Repair Windows.

An architecture firm is considering upgrading its computer-aided design (CAD) software to the newest version that forces storage of backups of all CAD files on the software's cloud server. Which of the following is MOST likely to be of concern to the IT manager?
A. Large update and installation files will overload the local hard drives.
B. Network utilization will be significantly increased due to the size of CAD files
C. Extra technician hours must be budgeted during installation of updates
D. All updated software must be tested with alt system types and accessories
正解：B
解説：
Explanation
The IT manager is most likely to be concerned about network utilization being significantly increased due to the size of CAD files. Backing up all CAD files to the software's cloud server can result in a large amount of data being transferred over the network, which can cause network congestion and slow down other network traffic.
質問 # 732
The calendar application on an employee's smartphone is experiencing frequent crashes, and the smartphone has become unresponsive. Which of the following should a technician do first to resolve the issue?
A. Reboot the smartphone.
B. Reinstall the application on the smartphone.
C. Reset the smartphone to factory settings.
D. Update the smartphone's OS.
正解：A
解説：
Explanation
Rebooting the smartphone is the first and simplest step to resolve the issue of frequent crashes and unresponsiveness. Rebooting clears the memory, closes the background apps, and refreshes the system. It can also fix minor glitches and bugs that may cause the calendar app or the smartphone to malfunction12. The other options are either too drastic or unnecessary. Reinstalling the application may not solve the problem if the issue is with the smartphone itself. Updating the smartphone's OS may not be possible or helpful if the device is unresponsive or incompatible. Resetting the smartphone to factory settings will erase all the data and settings on the device, which should be the last resort.
