Question 241.

Which server component stores configuration settings when system power is removed?

  1. CMOS memory
  2. CPU cache
  3. Video buffer
  4. Kernel memory

Correct Answer: 1

Explanation:

CMOS memory traditionally stores firmware-related configuration information that must remain available when the server is powered off. Examples can include hardware settings, boot preferences, and system configuration values. Modern systems may implement these functions using nonvolatile memory technologies rather than traditional CMOS circuitry, but the term remains common in server administration. A small battery can maintain power for certain configuration storage mechanisms when required. If configuration settings repeatedly reset after shutdown, administrators should investigate the firmware storage mechanism, battery condition, and motherboard hardware. Incorrect firmware settings can also cause startup, device-detection, or boot-order problems.

Question 242.

Which feature helps a server continue operating after one cooling fan fails?

  1. Passive heat dissipation
  2. Independent airflow channels
  3. Redundant fan assembly
  4. Adjustable chassis vents

Correct Answer: 3

Explanation:

A redundant fan assembly provides additional cooling capacity so that a server can continue operating when an individual fan fails. Enterprise servers commonly use multiple hot-swappable or independently monitored fans to maintain sufficient airflow during component failures. The management firmware may detect a failed fan and automatically increase the speed of remaining fans. Administrators should replace failed cooling hardware promptly even when the server remains operational because the remaining fans may be operating under greater load. Cooling redundancy is particularly important for densely populated systems where processors, memory, and storage devices generate substantial heat inside a compact chassis.

Question 243.

What does a server’s asset tag primarily help an organization manage?

  1. Network routing decisions
  2. Hardware identification
  3. Processor scheduling
  4. Filesystem permissions

Correct Answer: 2

Explanation:

An asset tag provides a unique identifier that helps an organization track physical equipment throughout its lifecycle. Asset-management systems can associate the identifier with information such as purchase details, assigned location, warranty status, maintenance history, and ownership records. Tags may be printed labels, barcodes, QR codes, or other identification methods. They do not directly control server networking or operating-system behavior. When equipment is moved, repaired, replaced, or retired, administrators can use the asset identifier to maintain accurate inventory records. Reliable asset tracking is especially valuable in environments containing many similar servers and other infrastructure components.

Question 244.

Which server feature allows a failed drive to be replaced without shutting down the system?

  1. Offline servicing
  2. Static drive installation
  3. Fixed-bay mounting
  4. Hot-swappable drive bay

Correct Answer: 4

Explanation:

A hot-swappable drive bay allows a supported storage device to be removed and replaced while the server remains powered on. This capability is common in enterprise storage systems where continuous availability is important. The storage controller, backplane, operating system, and drive enclosure must all support the appropriate hot-swap behavior. Administrators should confirm that the failed drive has been correctly identified before removal because taking out the wrong disk can cause additional problems, particularly in redundant storage configurations. After installing the replacement, the controller may begin a rebuild or other recovery process depending on the storage architecture.

Question 245.

Which maintenance action removes dust that can restrict airflow through server cooling paths?

  1. Cleaning intake and exhaust areas
  2. Increasing processor voltage
  3. Disabling temperature monitoring
  4. Reducing memory capacity

Correct Answer: 1

Explanation:

Cleaning server intake and exhaust areas helps maintain proper airflow through the chassis. Dust accumulation can obstruct vents, filters, heatsinks, and fan assemblies, increasing internal temperatures and forcing cooling fans to operate at higher speeds. During maintenance, administrators should follow the equipment manufacturer’s cleaning procedures and avoid practices that could generate static discharge or physically damage components. Environmental conditions also matter because servers installed in dusty locations may require more frequent inspection. Preventive cleaning should be documented as part of routine maintenance. Good airflow helps maintain stable operating temperatures and reduces thermal stress on critical components.

Question 246.

Which protocol is commonly used to synchronize server clocks with a trusted time source?

  1. SMB
  2. NTP
  3. FTP
  4. SNMP

Correct Answer: 2

Explanation:

The Network Time Protocol, or NTP, synchronizes system clocks with designated time sources. Accurate server time is important for authentication, certificate validation, event correlation, distributed applications, scheduled operations, and troubleshooting. Organizations commonly configure servers to use approved internal time sources rather than allowing every system to independently select public sources. Large clock differences can cause authentication failures or make log analysis difficult because events appear to occur in an incorrect order. Administrators should monitor synchronization status and investigate excessive clock drift. Reliable time synchronization is especially important when multiple servers participate in distributed services or security monitoring.

Question 247.

What does a server’s management controller typically allow administrators to do remotely?

  1. Replace application source code
  2. Modify database records
  3. Monitor hardware health
  4. Reorganize filesystem directories

Correct Answer: 3

Explanation:

A dedicated server management controller can provide remote access to hardware-level information and controls. Depending on the platform, administrators may monitor temperatures, fan conditions, power status, hardware alerts, and component health. Some implementations also provide remote console access and power-management functions even when the operating system is unavailable. Vendor-specific technologies may use different names and interfaces, but the general purpose is similar: provide management capabilities independent of normal operating-system access. Administrators should protect these interfaces with strong authentication, restricted network access, and appropriate administrative controls because compromise of the management plane can provide extensive hardware-level access.

Question 248.

Which practice helps prevent unauthorized physical access to rack-mounted servers?

  1. Disabling system logging
  2. Removing inventory records
  3. Sharing administrator credentials
  4. Securing the equipment enclosure

Correct Answer: 4

Explanation:

Securing the equipment enclosure helps restrict unauthorized physical access to servers and networking hardware. Physical security can include locked rack doors, controlled access to server rooms, surveillance, visitor procedures, and appropriate environmental controls. Physical access can create risks that cannot be fully addressed through operating-system security alone because someone with direct access may interact with hardware, storage media, console interfaces, or power controls. Administrators should also maintain records of authorized personnel and follow organizational access procedures. Physical protection is especially important for servers containing sensitive information because hardware theft or unauthorized manipulation can compromise confidentiality and availability.

Question 249.

Which measurement indicates how long a server service takes to respond to a request?

  1. Response latency
  2. Storage capacity
  3. CPU frequency
  4. Memory density

Correct Answer: 1

Explanation:

Response latency represents the time between a request being made and the corresponding response being received. It is an important performance measurement for applications, databases, storage systems, and network services. Low latency generally means requests are completed quickly, while higher latency can make an application feel slow even when overall throughput remains high. Administrators should measure latency in the context of the specific workload because acceptable values differ between applications. When latency increases, troubleshooting may involve processor load, memory pressure, storage behavior, network conditions, application processing, or backend dependencies. Performance monitoring can help identify where delays originate.

Question 250.

Which storage interface connects directly to PCI Express lanes for high-speed solid-state storage?

  1. SATA
  2. SAS
  3. NVMe
  4. PATA

Correct Answer: 3

Explanation:

NVMe is a storage protocol designed for non-volatile memory devices and commonly operates over PCI Express. It was developed to take advantage of the parallelism and low latency available from modern flash storage technologies. Compared with older storage protocols designed around mechanical disks, NVMe can support large numbers of command queues and commands, making it suitable for high-performance server workloads. Administrators should distinguish NVMe as a protocol from PCI Express as the underlying interconnect in many implementations. When selecting NVMe hardware, compatibility with the server’s physical slots, firmware, operating system, thermal design, and supported drive formats should be verified.

Question 251.

What is the purpose of a server’s hardware compatibility list?

  1. Identifying approved component combinations
  2. Recording employee attendance
  3. Measuring application response times
  4. Assigning network addresses

Correct Answer: 1

Explanation:

A hardware compatibility list identifies components that have been validated or officially supported for a particular server platform. It may cover processors, memory modules, storage devices, expansion adapters, power supplies, or other replaceable hardware. Following the approved list reduces the risk of installing components that are electrically, mechanically, thermally, or firmware incompatible. Administrators should consult current vendor documentation before purchasing replacement hardware, especially for systems with strict platform requirements. Compatibility information can also identify required firmware revisions or supported configurations. Using an unapproved component may result in detection problems, reduced functionality, instability, or the loss of vendor support.

Question 252.

Which server capability permits administrators to boot from a remote network image during deployment?

  1. Local optical installation
  2. Network-based provisioning
  3. Internal recovery partition
  4. Removable-media setup

Correct Answer: 2

Explanation:

Network-based provisioning allows a server to obtain installation or deployment resources from infrastructure on the network. Organizations can use this approach to install operating systems, deploy standardized server configurations, or automate provisioning across many machines. A provisioning environment typically includes a network service, deployment image, configuration files, and appropriate firmware or boot support. This method reduces the need to physically visit each server with installation media. Administrators should secure provisioning infrastructure because unauthorized access to deployment services could allow an attacker to introduce an unapproved operating-system image or configuration onto a server.

Question 253.

Which technology encrypts an entire storage volume so data remains protected if the disk is removed?

  1. Full-volume encryption
  2. File indexing
  3. Storage compression
  4. Directory replication

Correct Answer: 1

Explanation:

Full-volume encryption protects data across an entire storage volume by encrypting its contents. If an unauthorized person removes the physical disk and attempts to access it from another system, the encrypted information remains protected without the required authentication or cryptographic key. Implementations may use technologies such as BitLocker or Linux-based encryption mechanisms depending on the operating environment. Administrators must plan key management carefully because losing the recovery information can make protected data inaccessible. Encryption at rest should also be combined with appropriate access controls, backups, and secure administrative practices rather than being treated as the only security measure.

Question 254.

Which DNS record identifies the mail server responsible for receiving email for a domain?

  1. PTR record
  2. TXT record
  3. MX record
  4. CNAME record

Correct Answer: 3

Explanation:

An MX, or Mail Exchange, record identifies the mail-handling server associated with a domain. When a sending mail system needs to deliver a message, it can query DNS for the destination domain’s MX records and determine which mail servers should receive the message. MX records can include preference values so that multiple servers can be arranged according to delivery priority. Administrators managing email infrastructure should ensure that MX records point to the intended mail-handling systems and that corresponding hostnames resolve correctly. DNS changes may also require consideration of TTL values because cached information can remain available for a period of time.

Question 255.

What does a firewall rule’s source port identify?

  1. The originating transport-layer port
  2. The destination server’s hostname
  3. The physical network connector
  4. The filesystem access point

Correct Answer: 1

Explanation:

A source port identifies the transport-layer port associated with the originating side of a TCP or UDP communication. Firewalls can evaluate source and destination addresses, ports, protocols, connection state, and other attributes when determining whether traffic should be permitted. Client applications often use temporary source ports when establishing connections to services listening on known destination ports. Administrators should understand the difference between source and destination ports when designing firewall rules because reversing them can produce unexpected connectivity behavior. Firewall policies should be tested carefully after changes, especially on production servers where an incorrect rule may block legitimate application traffic.

Question 256.

Which server technology distributes incoming application requests across multiple backend systems?

  1. Storage replication
  2. Load balancing
  3. Disk partitioning
  4. Memory interleaving

Correct Answer: 2

Explanation:

Load balancing distributes incoming client requests across multiple backend systems. This can improve resource utilization, increase service availability, and allow workloads to scale beyond the capacity of a single server. A load balancer may use different algorithms to select backend systems, and it can often perform health checks to avoid sending requests to unavailable instances. Some applications also require session persistence so that a user’s requests continue reaching an appropriate backend. Administrators should consider traffic patterns, health-check behavior, encryption handling, application state, and failure scenarios when designing a load-balanced service.

Question 257.

Which Linux utility is commonly used to display detailed information about network interfaces?

  1. ip
  2. tar
  3. sed
  4. df

Correct Answer: 1

Explanation:

The Linux ip utility provides commands for inspecting and managing networking components such as interfaces, addresses, routes, and related configuration. Administrators can use it to investigate whether an interface is present, determine assigned addresses, inspect link state, and examine routing information. The utility is widely used on modern Linux distributions and provides functionality that replaces several older networking commands. When troubleshooting connectivity, administrators should examine interface state alongside addressing, routing, DNS, firewall policy, and physical connectivity. Using the appropriate ip subcommand allows a technician to gather detailed information without relying entirely on graphical management tools.

Question 258.

What does configuration drift describe in server administration?

  1. Unauthorized physical relocation
  2. Gradual deviation from an approved configuration
  3. Expansion of storage capacity
  4. Increase in network bandwidth

Correct Answer: 2

Explanation:

Configuration drift occurs when a server gradually differs from its approved or intended configuration. Changes may result from manual modifications, emergency troubleshooting, software installations, patching, configuration changes, or inconsistent administrative practices. Over time, these differences can create security, reliability, and support problems because systems that should be identical no longer behave consistently. Administrators can reduce configuration drift by using standardized templates, automated configuration management, version-controlled definitions, and regular compliance checks. When drift is detected, the organization can compare the current state with its approved baseline and determine whether the difference is intentional or requires correction.

Question 259.

Which backup property prevents stored recovery data from being modified during its retention period?

  1. Immutable retention
  2. Temporary caching
  3. Dynamic compression
  4. Incremental indexing

Correct Answer: 1

Explanation:

Immutable retention prevents protected backup data from being altered or deleted during a defined retention period. This capability can help defend recovery copies against accidental modification, malicious deletion, or ransomware-related attacks that attempt to compromise accessible backups. The exact implementation varies between backup platforms and storage systems. Administrators should configure retention periods according to business and regulatory requirements and ensure that recovery procedures are tested. Immutability does not replace the need for multiple backup copies, appropriate access controls, or disaster-recovery planning. A protected backup is useful only if the organization can locate it, access it appropriately, and successfully restore required data.

Question 260.

Which document provides step-by-step instructions for performing a recurring server operation?

  1. Asset register
  2. Runbook
  3. Purchase order
  4. Warranty certificate

Correct Answer: 2

Explanation:

A runbook provides documented, repeatable instructions for performing a specific operational task. Server administrators may use runbooks for activities such as service recovery, maintenance procedures, backup verification, incident response, or controlled system changes. A well-designed runbook can identify prerequisites, commands or actions, validation steps, expected results, escalation conditions, and rollback procedures. This reduces dependence on individual administrator memory and promotes consistent execution across a team. Runbooks should be reviewed and updated when systems or procedures change. Organizations may also link runbooks with monitoring alerts or ticketing processes so technicians can quickly follow the correct operational procedure.
