質問 # 46
A server technician is installing a Windows server OS on a physical server. The specifications for the installation call for a 4TB data volume. To ensure the partition is available to the OS, the technician must verify the:
- A. hardware is UEFI compliant
- B. volume is formatted as MBR
- C. volume is formatted as GPT
- D. volume is spanned across multiple physical disk drives
正解：C
解説：
To ensure the partition is available to the OS, the technician must verify that the volume is formatted as GPT. GPT (GUID Partition Table) is a partitioning scheme that defines how data is organized on a hard disk drive (HDD) or a solid state drive (SSD). GPT uses globally unique identifiers (GUIDs) to identify partitions and supports up to 128 primary partitions per disk. GPT also supports disks larger than 2 TB and has a backup copy of the partition table at the end of the disk for data recovery. GPT is required for installing Windows on UEFI-based PCs, which offer faster boot time and better security than legacy BIOS-based PCs.

Bollards are sturdy posts that are installed around a perimeter to prevent vehicles from entering or crashing into a protected area. Bollards can provide physical security and deterrence for datacenters that are located near busy roads or parking lots. Bollards can also prevent accidental damage or injury caused by vehicles that lose control or have faulty brakes.
質問 # 51
A company wants to deploy software to all users, Out very few of men will be using the software at any one point in time. Which of the following licensing models would be BEST lot the company?
- A. Per site
- B. Per instance
- C. Per core
- D. Per concurrent user
正解：D
解説：
Explanation
Per concurrent user licensing is a model that allows a fixed number of users to access the software at any one point in time. This model is best for the company that wants to deploy software to all users, but very few of them will be using the software at any one point in time. This way, the company can save money by paying only for the number of simultaneous users, rather than for every user who has access to the software. Per site licensing is a model that allows unlimited users within a specific location to use the software. Per core licensing is a model that charges based on the number of processor cores on the server where the software is installed. Per instance licensing is a model that charges based on the number of copies of the software running on different servers or virtual machines. References:

The management team has mandated the encryption of all server administration traffic. Which of the following should MOST likely be implemented?
- A. SSH
- B. SELinux
- C. VPN
- D. FTPS
正解：A
解説：
Explanation
SSH stands for Secure Shell and it is a network protocol that provides encrypted and authenticated communication between two hosts. SSH can be used to remotely access and administer a server using a command-line interface or a graphical user interface. SSH can ensure the encryption of all server administration traffic, which can prevent eavesdropping, tampering, or spoofing by unauthorized parties.

質問 # 53
An administrator is installing a new file server that has four drive bays available. Which of the following RAID types would provide the MOST storage as well as disk redundancy?
- A. RAID 1
- B. RAID 5
- C. RAID 10
- D. RAIDO
正解：B
解説：
Explanation
RAID 5 is a RAID level that provides striping with parity, which means that data is distributed across all disks with one disk storing parity information for error correction. RAID 5 can tolerate one disk failure without losing data. RAID 5 provides the most storage as well as disk redundancy out of the four RAID levels given, since it only uses one disk for parity and the rest for data. For example, if four 200GB drives are used in a RAID 5 array, the total storage capacity would be 600GB (200GB x 3), while in RAID 0 it would be 800GB (200GB x 4), in RAID 1 it would be 200GB (200GB x 1), and in RAID 10 it would be 400GB (200GB x 2).

Which of the following BEST describes the concept of right to downgrade?
- A. It allows a server to run on fewer resources than what is outlined in the minimum requirements document without purchasing a license
- B. It allows for a previous version of an OS to be deployed in a test environment for each current license that is purchased
- C. It allows for the return of a new OS license if the newer OS is not compatible with the currently installed software and is returning to the previously used OS
- D. It allows a previous version of an OS to be installed and covered by the same license as the newer version
正解：D
解説：
Explanation
The concept of right to downgrade allows a previous version of an OS to be installed and covered by the same license as the newer version. For example, if a customer has a license for Windows 10 Pro, they can choose to install Windows 8.1 Pro or Windows 7 Professional instead and still be compliant with the license terms.
Downgrade rights are granted by Microsoft for certain products and programs, such as Windows and Windows Server software acquired through Commercial Licensing, OEM, or retail channels. Downgrade rights are intended to provide customers with flexibility and compatibility when using Microsoft software.

質問 # 64
The network's IDS is giving multiple alerts that unauthorized traffic from a critical application server is being sent to a known-bad public IP address.
One of the alerts contains the following information:
Exploit Alert
Attempted User Privilege Gain
2/2/07-3: 09:09 10.1.200.32
--> 208.206.12.9:80
This server application is part of a cluster in which two other servers are also servicing clients. The server administrator has verified the other servers are not sending out traffic to that public IP address. The IP address subnet of the application servers is 10.1.200.0/26. Which of the following should the administrator perform to ensure only authorized traffic is being sent from the application server and downtime is minimized? (Select two).
- A. Block access to 208.206.12.9 from all servers on the network.
- B. Change the IP address of all the servers in the cluster to the 208.206.12.0/26 subnet.
- C. Disable all services on the affected application server.
- D. Enable GPO to install an antivirus on all the servers and perform a weekly reboot.
- E. Perform a vulnerability scan on all the servers within the cluster and patch accordingly.
- F. Perform an antivirus scan on all servers within the cluster and reboot each server.
正解：E、F
解説：
Explanation
The administrator should perform an antivirus scan on all servers within the cluster and reboot each server, and block access to 208.206.12.9 from all servers on the network. These actions will help to remove any malware that may have infected the application server and prevent any further unauthorized traffic to the known-bad public IP address. An antivirus scan can detect and remove malicious software that may be sending data to an external source, and a reboot can clear any temporary files or processes that may be related to the malware. Blocking access to 208.206.12.9 from all servers on the network can prevent any future attempts to communicate with the malicious IP address.
