A systems administrator has noticed performance degradation on a company file server, and one of the disks on it has a solid amber light. The administrator logs on to the disk utility and sees the array is rebuilding. Which of the following should the administrator do NEXT once the rebuild is finished?
A. Restore the server from a snapshot.
B. Restore the server from backup.
C. Swap the drive and initialize the disk.
D. Swap the drive and initialize the array.
Correct Answer: C
The next action that the administrator should take once the rebuild is finished is to swap the drive and initialize the disk. This is to replace the faulty disk that has a solid amber light, which indicates a predictive failure or a SMART error.
Initializing the disk will prepare it for use by the RAID controller and add it to the array. The administrator should also monitor the array status and performance after swapping the drive.
A technician wants to limit disk usage on a server. Which of the following should the technician implement?
A. Formatting
B. Compression
C. Disk quotas
D. Partitioning
Correct Answer: C
Disk quotas are a way to limit disk usage on a server by setting a maximum amount of space that each user or group can use. Disk quotas can help manage disk space allocation, prevent disk space exhaustion, and enforce fair usage
policies. Disk quotas can be set at the volume level or at the folder level, depending on the file system and operating system used.
A remote physical server is unable to communicate to the network through the available NICs, which were misconfigured. However, the server administrator is still able to configure the server remotely. Which of the following connection types is the server administrator using to access the server?
A. Out-of-band management
B. Crash cart access
C. Virtual administrator console
D. Local KVM setup
E. RDP connection
Correct Answer: A
The connection type that the server administrator is using to access the server remotely is out-of-band management. Out-of-band management is a method of accessing and controlling a server through a dedicated network interface or port that is separate from the regular data network. Out-of-band management allows administrators to perform tasks such as rebooting, configuring, troubleshooting, or updating a server even if the server is offline or unresponsive through the regular network. Out-of-band management can use protocols such as IPMI, iLO, DRAC, or BMC. Reference: https://www.ibm.com/cloud/learn/out-of-band-management
Question 264:
A server administrator needs to configure a server on a network that will have no more than 30 available IP addresses. Which of the following subnet addresses will be the MOST efficient for this network?
A. 255.255.255.0
B. 255.255.255.128
C. 255.255.255.224
D. 255.255.255.252
Correct Answer: C
The most efficient subnet address for a network that will have no more than 30 available IP addresses is 255.255.255.224. This subnet mask corresponds to a /27 prefix length, which means that 27 bits are used for the network portion and 5 bits are used for the host portion of an IP address. With 5 bits for hosts, there are 2^5 - 2 = 30 possible host addresses per subnet, which meets the requirement. The other options are either too large or too small for the network size.
A server administrator added a new drive to a server. However, the drive is not showing up as available. Which of the following does the administrator need to do to make the drive available?
A. Partition the drive.
B. Create a new disk quota.
C. Configure the drive as dynamic.
D. Set the compression.
Correct Answer: A
To make a new drive available on a server, the administrator needs to partition the drive first. Partitioning is a process that divides the drive into one or more logical sections that can be formatted and assigned drive letters or mount points. Partitioning can be done using tools such as Disk Management on Windows or fdisk on Linux. Creating a new disk quota would not help, as disk quotas are used to limit the amount of disk space that users or groups can use on a partition. Configuring the drive as dynamic would not help either, as dynamic disks are used to create volumes that span multiple disks or use RAID features. Setting the compression would not help, as compression is used to reduce the size of files on a partition.
Which of the following encryption methodologies would MOST likely be used to ensure encrypted data cannot be retrieved if a device is stolen?
A. End-to-end encryption
B. Encryption in transit
C. Encryption at rest
D. Public key encryption
Correct Answer: C
Encryption at rest is a type of encryption methodology that would most likely be used to ensure encrypted data cannot be retrieved if a device is stolen. Encryption at rest is a process of encrypting stored data on a device such as a hard drive,
SSD, USB flash drive, or mobile device. This way, if the device is lost or stolen, the data cannot be accessed without the encryption key or password. Encryption at rest can be implemented using software tools such as BitLocker on Windows
or FileVault on Mac OS, or hardware features such as self-encrypting drives or Trusted Platform Module chips. End-to-end encryption is a type of encryption methodology that ensures encrypted data cannot be intercepted or modified by third
parties during transmission over a network. Encryption in transit is a type of encryption methodology that protects encrypted data while it is moving from one location to another over a network. Public key encryption is a type of encryption
algorithm that uses a pair of keys: a public key that can be shared with anyone and a private key that is kept secret by the owner.
A server technician notices a server is very low on disk space. Upon inspecting the disk utilization, the technician discovers server logs are taxing up a large amount of space. There is no central log server. Which of the following would help free up disk space?
A. Log rotation
B. Log shipping
C. Log alerting
D. Log analysis
Correct Answer: A
Log rotation is a process of automatically moving old log files to an archive location and creating new log files. It helps to prevent the accumulation of old log files that can take up a large amount of disk space. By implementing log rotation, the server technician can ensure that the server logs are managed and maintained in a more efficient way, freeing up disk space.
Log shipping is a process of forwarding log data to a central log server, which is not relevant to this scenario as there is no central log server. Log alerting is a process of generating alerts when specific events occur in the log files, which is not directly relevant to freeing up disk space. Log analysis is the process of analyzing log data to identify trends, patterns, and potential issues, which also does not directly address the issue of low disk space.
Question 268:
Users have noticed a server is performing below Baseline expectations. While diagnosing me server, an administrator discovers disk drive performance has degraded. The administrator checks the diagnostics on the RAID controller and sees the battery on me controller has gone bad.
Which of the following is causing the poor performance on the RAID array?
A. The controller has disabled the write cache.
B. The controller cannot use all the available channels.
C. The drive array is corrupt.
D. The controller has lost its configuration.
Correct Answer: A
The write cache is a feature of some RAID controllers that allows them to temporarily store data in a fast memory buffer before writing it to the disk drives. This improves the performance and efficiency of write operations, especially for random and small writes. However, if the battery on the controller goes bad, the controller may disable the write cache to prevent data loss in case of a power failure. This can degrade the disk drive performance significantly, as every write operation will have to wait for the disk drives to complete.
A server administrator is completing an OS installation for a new server. The administrator patches the server with the latest vendor-suggested software, configures DHCP, and verifies all network cables are properly connected in the IDF, but there is no network connectivity. Which of the following is the MOST likely reason for the lack of connectivity?
A. The VLAN Is improperly configured.
B. The DNS configuration Is invalid.
C. The OS version is not compatible with the network switch vendor.
D. The HIDS is preventing the connection.
Correct Answer: A
If the server administrator patches the server with the latest vendor- suggested software, configures DHCP, and verifies all network cables are properly connected in the IDF, but there is no network connectivity, then the most likely reason for
the lack of connectivity is that the VLAN is improperly configured. A VLAN (Virtual Local Area Network) is a logical grouping of network devices that share the same broadcast domain and can communicate with each other without routing. If
the server is assigned to a different VLAN than the DHCP server or the default gateway, it will not be able to obtain an IP address or reach other network devices. The DNS configuration is not relevant for network connectivity, as DNS only
resolves names to IP addresses. The OS version is not likely to be incompatible with the network switch vendor, as most network switches use standard protocols and interfaces. The HIDS (Host-based Intrusion Detection System) is not likely
to prevent the connection, as HIDS only monitors and alerts on suspicious activities on the host.
