An organization stores backup tapes of its servers at cold sites. The organization wants to ensure the tapes are properly maintained and usable during a DR scenario. Which of the following actions should the organization perform?
Correct Answer:
C
The organization should retrieve the tapes from the cold site and test them to ensure they are properly maintained and usable during a DR scenario. A cold site is a location that has space and power for backup equipment, but no actual equipment installed or configured. The organization stores backup tapes of its servers at cold sites as a precaution in case of a disaster that affects its primary site. However, backup tapes can degrade over time due to environmental factors such as temperature, humidity, dust, or magnetic fields. Therefore, the organization should periodically retrieve the tapes from the cold site and test them on compatible equipment to verify their integrity and readability.

An administrator is configuring the storage for a new database server, which will host databases that are mainly used for archival lookups. Which of the following storage types
will yield the fastest database read performance?
Correct Answer:
B
The storage type that will yield the fastest database read performance is SSD. SSD (Solid State Drive) is a type of storage device that uses flash memory to store data. SSDs have no moving parts and can access data faster than traditional hard disk drives (HDDs) that use spinning platters and magnetic heads. SSDs are especially suitable for databases that are mainly used for archival lookups, as they can provide faster response times and lower latency for read operations.

A technician is connecting a Linux server to a share on a NAS. Which of the following is the MOST appropriate native protocol to use for this task?
Correct Answer:
D
The most appropriate native protocol to use for connecting a Linux server to a share on a NAS is NFS. NFS (Network File System) is a protocol that allows file sharing and remote access over a network. NFS is designed for Unix-like operating systems, suchas Linux, and supports features such as symbolic links, hard links, file locking, and file permissions. NFS uses mount points to attach remote file systems to local file systems, making them appear as if they are part of the local file system. NFS can provide fast and reliable access to files stored on a NAS (Network Attached Storage), which is a device that provides centralized storage for network devices.
A security analyst suspects a remote server is running vulnerable network applications. The analyst does not have administrative credentials for the server. Which of the following would MOST likely help the analyst determine if the applications are running?
Correct Answer:
D
A port scanner is the tool that would most likely help the analyst determine if the applications are running on a remote server. A port scanner is a software tool that scans a network device for open ports. Ports are logical endpoints for network communication that are associated with specific applications or services. By scanning the ports on a remote server, the analyst can identify what applications or services are running on that server and what protocols they are using. A port scanner can also help detect potential vulnerabilities or misconfigurations on a server.
A technician needs to install a Type 1 hypervisor on a server. The server has SD card slots, a SAS controller, and a SATA controller, and it is attached to a NAS. On which of the following drive types should the technician install the hypervisor?
Correct Answer:
D
The technician should install the Type 1 hypervisor on a SAS drive. A Type 1 hypervisor is a layer of software that runs directly on top of the physical hardware and creates virtual machines that share the hardware resources. A Type 1 hypervisor requires fast and reliable storage for optimal performance and stability. A SAS drive is a type of hard disk drive that uses Serial Attached SCSI (SAS) as its interface protocol. SAS drives offer high speed, low latency, and high reliability compared to other types of drives, such as SD cards, NAS drives, or SATA drives. SD cards are flash memory cards that offer low cost and portability but have low speed, low capacity, and low durability. NAS drives are network-attached storage devices that offer high capacity and easy access but have high latency and low reliability due to network dependency. SATA drives are hard disk drives that use Serial ATA (SATA) as their interface protocol. SATA drives offer moderate speed, moderate cost, and moderate reliability but have lower performance and durability than SAS drives.
