Correct Answer: B

Dynamic disk is a technology that allows an administrator to build a software RAID on a Windows server. Dynamic disk is a type of disk management that supports creating volumes that span multiple disks, stripe data across disks, mirror

data between disks, or use parity for fault tolerance. Dynamic disk can be used to create RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), or spanned volumes on Windows servers. Logical volume management is a

technology that allows creating and resizing logical volumes on Linux servers. GPT (GUID Partition Table) is a standard for defining the partition structure on a disk. UEFI (Unified Extensible Firmware Interface) is a specification for the

interface between the operating system and the firmware.

Correct Answer: C

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.

Correct Answer: D

The server administrator needs to adhere to the Service Level Agreement (SLA) when responding to tickets within a certain amount of time. An SLA is a contract between a service provider and a customer that defines the quality, availability, and responsibilities of the service. An SLA may specify the response time for tickets, as well as other metrics such as uptime, performance, security, and backup frequency.

Correct Answer: C

The reason why the Linux server is not communicating on a network is that it is configured to use DHCP on a network that does not have a DHCP server. DHCP (Dynamic Host Configuration Protocol) is a protocol that allows a client device to obtain an IP address and other network configuration parameters from a DHCP server automatically. However, if there is no DHCP server on the network, the client device will not be able to obtain a valid IP address and will assign itself a link-local address instead. A link-local address is an IP address that is only valid within a local network segment and cannot be used for communication outside of it. A link-local address has a prefix of 169.254/16 in IPv4 or fe80::/10 in IPv6. In this case, the Linux server has assigned itself a link-local address of 127.0.0.1, which is also known as the loopback address. The loopback address is used for testing and troubleshooting purposes and refers to the device itself. It cannot be used for communication with other devices on the network.

Correct Answer: C

The server installation method that would optimize server resources is core. Core is a minimal installation option that is available for some operating systems, such as Windows Server and Linux. Core installs only the essential components and features of the operating system, without any graphical user interface (GUI) or other unnecessary services or applications. Core reduces the disk footprint, memory usage, CPU consumption, and attack surface of the server, making it more efficient and secure. Core can be managed remotely using command-line tools, PowerShell, or GUI tools.

Explanation: GPT (GUID Partition Table) is a partitioning scheme that allows creating partitions on large hard drives (more than 2 TB). It supports up to 128 partitions per drive and uses 64-bit addresses to locate them. MBR (Master Boot Record) is an older partitioning scheme that has limitations on the size and number of partitions (up to 4 primary partitions or 3 primary and 1 extended partition per drive). To provision a new 4 TB drive, the technician should partition it using GPT. Verified References: [GPT], [MBR]

Correct Answer: A

A backdoor is a security risk that provides unauthorized access to an application. A backdoor is a hidden or undocumented way of bypassing the normal authentication or encryption mechanisms of an application, allowing an attacker to gain remote access, execute commands, or steal data. A backdoor can be created intentionally by the developer, maliciously by an attacker, or unintentionally by a programming error.
