Question 101.

Which technology combines several physical network connections into one logical link?

1. NIC bonding
2. Traffic inspection
3. Route filtering
4. Packet encapsulation

Correct Answer: 1

Explanation:

NIC bonding combines multiple physical network interfaces into a logical network connection. Depending on the configuration, it can provide redundancy, increased throughput, or both. If one physical interface fails, another member of the bonded group may continue carrying traffic. Traffic inspection examines network packets, route filtering controls which routes are accepted, and packet encapsulation places one protocol inside another. Server administrators commonly configure interface bonding when network availability is important or when a server requires additional network capacity. The exact bonding mode should match the capabilities of the operating system and connected network infrastructure.

Question 102.

Which storage technology provides block-level access over an Ethernet-based network?

1. Network share
2. File gateway
3. iSCSI target
4. Directory namespace

Correct Answer: 3

Explanation:

An iSCSI target provides block-level storage access through an IP-based network. A server acting as an iSCSI initiator can discover and connect to storage resources presented by the target. The operating system can then treat the presented storage as a block device that can be partitioned or formatted as needed. A network share provides file-level access, a file gateway provides access between systems and storage services, and a directory namespace organizes shared resources. Block-level storage is useful when applications or operating systems require direct access to virtual disks rather than individual files.

Question 103.

Which virtualization capability transfers an active virtual machine between compatible physical hosts?

1. Workload templating
2. Live workload migration
3. Virtual machine cloning
4. Guest image export

Correct Answer: 2

Explanation:

Live workload migration moves an active virtual machine from one physical host to another while minimizing service interruption. Administrators can use this capability during hardware maintenance, resource balancing, or host servicing. Workload templating creates systems from predefined configurations, virtual machine cloning creates a duplicate guest, and guest image export produces a portable representation of a virtual machine. Migration generally requires compatible processor features, suitable networking, and access to the necessary virtual machine storage. Administrators should verify platform compatibility and available resources before moving an important production workload.

Question 104.

Which device distributes client requests among several application servers?

1. Network repeater
2. Session broker
3. Application distributor
4. Traffic load balancer

Correct Answer: 4

Explanation:

A traffic load balancer distributes incoming client requests across multiple backend servers. This arrangement can improve scalability because additional servers can share application workloads. It can also improve availability by avoiding dependence on one backend system. A network repeater regenerates signals, a session broker manages selected session-related functions, and an application distributor is not the standard server component used for general workload balancing. Load balancers may perform health checks and stop sending traffic to unhealthy backend systems. Their configuration should match application requirements and expected traffic patterns.

Question 105.

Which protocol is commonly used to centralize event messages from servers and network equipment?

1. Syslog protocol
2. Directory Access Protocol
3. Authentication Exchange Protocol
4. Address Assignment Protocol

Correct Answer: 1

Explanation:

Syslog protocol is commonly used to send event messages from servers, network devices, applications, and other infrastructure components to a centralized logging system. Centralized logs allow administrators to investigate incidents across multiple systems without checking each machine separately. Directory Access Protocol is associated with directory services, Authentication Exchange Protocol describes authentication-related communication, and Address Assignment Protocol is not the standard name for centralized event logging. Centralized logging also supports security monitoring because administrators can correlate events from different devices and identify patterns that may not be visible from a single server.

Question 106.

Which storage method allocates physical capacity as data is written instead of reserving all space immediately?

1. Static disk allocation
2. Thin storage allocation
3. Fixed volume reservation
4. Preallocated capacity mapping

Correct Answer: 2

Explanation:

Thin storage allocation allows a logical storage volume to appear larger than the physical capacity initially consumed. Physical space is allocated progressively as data is written. This can improve storage utilization because administrators do not have to reserve the entire logical capacity at the beginning. However, the underlying storage pool must be monitored carefully because physical exhaustion can cause applications to fail. Static disk allocation and fixed volume reservation consume or reserve capacity in advance, while preallocated capacity mapping does not describe the same dynamic allocation model. Capacity alerts are important when using thin storage.

Question 107.

Which hardware feature permits remote control of a server even when its operating system is unavailable?

1. Dedicated management processor
2. Software telemetry agent
3. Application watchdog service
4. Filesystem monitoring daemon

Correct Answer: 1

Explanation:

A dedicated management processor provides an independent management channel for server hardware. It can allow administrators to monitor hardware health, control server power, access remote console functions, and perform other management tasks even when the operating system has crashed or failed to boot. A software telemetry agent normally depends on the operating system, an application watchdog monitors software behavior, and a filesystem monitoring daemon tracks storage-related activity. Independent hardware management is especially valuable in remote data centers because administrators can troubleshoot or recover systems without physically visiting the server location.

Question 108.

Which storage feature preserves the state of a volume at a specific point in time?

1. Volume snapshot
2. Disk formatter
3. Sector analyzer
4. Partition utility

Correct Answer: 1

Explanation:

A volume snapshot preserves a point-in-time representation of a storage volume. Snapshots can be useful when administrators need a temporary recovery point, want to test changes, or need to preserve the state of data before performing an operation. Depending on the storage platform, snapshots may use copy-on-write or similar techniques instead of immediately duplicating every block. A disk formatter prepares storage for use, a sector analyzer examines storage sectors, and a partition utility manages partition structures. Snapshots should not automatically be considered a replacement for independent backups.

Question 109.

Which certificate mechanism identifies certificates that should no longer be trusted?

1. Certificate status list
2. Trust anchor record
3. Revocation list
4. Key usage extension

Correct Answer: 3

Explanation:

A revocation list identifies certificates that a certificate authority has invalidated before their normal expiration date. A certificate may be revoked because its private key was compromised, ownership information changed, or another security issue occurred. Certificate status information is important when systems determine whether a certificate remains trustworthy. A trust anchor establishes a trusted starting point for certificate validation, while a key usage extension describes permitted cryptographic purposes. Administrators managing certificates should consider expiration dates, trust chains, identity matching, and revocation information as part of certificate validation.

Question 110.

Which storage process eliminates repeated data blocks to conserve disk capacity?

1. Storage compaction
2. Data deduplication
3. Block rearrangement
4. Sector optimization

Correct Answer: 2

Explanation:

Data deduplication identifies identical pieces of information and stores them only once while maintaining references to the repeated content. This can substantially reduce storage consumption when datasets contain many duplicate blocks. Backup repositories often benefit from deduplication because multiple backup sets can contain large amounts of unchanged information. Storage compaction refers more generally to reducing or reorganizing stored information, block rearrangement changes physical organization, and sector optimization is not the standard term for duplicate-data removal. Administrators should evaluate CPU, memory, storage, and workload requirements before enabling deduplication.

Question 111.

Which network function allows private addresses to communicate through a public address?

1. Address translation gateway
2. Name resolution server
3. Configuration relay
4. Packet inspection bridge

Correct Answer: 1

Explanation:

An address translation gateway performs Network Address Translation between private and public addressing environments. It can allow multiple internal systems to access external networks while sharing one or more publicly routable addresses. Name resolution servers translate hostnames into address information, configuration relays forward certain network configuration requests, and packet inspection bridges examine or forward traffic at the network boundary. Address translation is especially common in IPv4 environments because private address ranges are not directly routable across the public Internet. Administrators should ensure that translation rules match the required services and connectivity design.

Question 112.

Which cloud capability automatically adjusts computing resources as workload demand changes?

1. Resource reservation
2. Manual scaling
3. Elastic scaling
4. Capacity locking

Correct Answer: 3

Explanation:

Elastic scaling automatically adjusts computing resources according to workload demand. A platform can increase resources when demand rises and reduce them when demand falls, depending on configured policies and supported architecture. This allows organizations to handle variable workloads without permanently maintaining maximum capacity. Resource reservation dedicates resources in advance, manual scaling requires administrator intervention, and capacity locking keeps resource levels fixed. Effective elastic scaling depends on appropriate monitoring metrics, thresholds, application design, and cooldown settings. Poorly configured policies can cause unnecessary resource changes or fail to respond quickly enough to workload increases.

Question 113.

Which technology creates an encrypted connection for remote access across an untrusted network?

1. Virtual private tunnel
2. Traffic duplication
3. Broadcast forwarding
4. Network bridging

Correct Answer: 1

Explanation:

A virtual private tunnel provides protected communication across an untrusted network by using encryption and authentication mechanisms appropriate to the VPN technology. It can connect remote users or separate networks while reducing exposure of transmitted information to unauthorized observers. Traffic duplication copies network packets for analysis, broadcast forwarding transfers certain broadcast traffic between network segments, and network bridging connects networks at the data-link layer. VPN configurations should use strong authentication and current cryptographic protocols. Administrators should also restrict remote access permissions so that connected users receive only the network access they require.

Question 114.

Which architecture provides centralized block storage through a dedicated storage network?

1. Storage Area Network
2. File sharing cluster
3. Application delivery network
4. Directory replication group

Correct Answer: 1

Explanation:

A Storage Area Network, or SAN, provides centralized block storage to connected servers through a dedicated storage networking architecture. SAN environments can support technologies such as Fibre Channel and other storage transport methods. They are commonly used when organizations require centralized storage, high availability, scalable capacity, and strong performance. A file sharing cluster primarily provides shared files, an application delivery network focuses on application traffic, and a directory replication group distributes identity information. SAN environments require careful planning of storage connectivity, redundant paths, access controls, and storage allocation.

Question 115.

Which authorization model assigns permissions according to predefined job functions?

1. Role-based authorization
2. Open permission model
3. Anonymous access scheme
4. Universal privilege assignment

Correct Answer: 1

Explanation:

Role-based authorization assigns permissions according to predefined roles associated with job responsibilities. Instead of configuring every permission separately for each employee, administrators can assign users to appropriate roles and manage permissions at the role level. This simplifies administration and helps maintain consistent access policies. An open permission model provides broader access, anonymous access removes meaningful identity requirements, and universal privilege assignment would provide excessive permissions rather than restricting them according to responsibilities. Roles should be reviewed regularly because employees can change positions or responsibilities over time.

Question 116.

Which storage feature provides multiple communication paths between a server and shared storage?

1. Multipath storage access
2. Single-channel attachment
3. Console forwarding
4. Local cache mirroring

Correct Answer: 1

Explanation:

Multipath storage access provides multiple communication paths between a server and its storage resources. If one path fails, another path can potentially maintain connectivity, improving storage availability. Some multipath implementations can also distribute I/O across available paths to improve utilization. Single-channel attachment does not provide equivalent redundancy, console forwarding concerns remote management communication, and local cache mirroring involves storage caching rather than physical path redundancy. Administrators should verify that the server, storage system, switches, and multipath software are configured consistently to avoid path conflicts or unexpected storage behavior.

Question 117.

Which troubleshooting method identifies the underlying reason a recurring server problem occurs?

1. Root cause analysis
2. Incident notification
3. Routine observation
4. Status reporting

Correct Answer: 1

Explanation:

Root cause analysis investigates the underlying reason behind a recurring incident rather than addressing only its visible symptoms. Administrators may review logs, configuration changes, dependencies, timelines, and environmental conditions to determine what actually caused the failure. Incident notification informs users or support teams about an issue, routine observation monitors normal behavior, and status reporting communicates current conditions. Root cause analysis is valuable after repeated outages or persistent faults because identifying the underlying cause allows administrators to implement corrective measures that reduce the likelihood of the same problem occurring again.

Question 118.

Which diagram documents where physical servers and networking equipment are installed within a rack?

1. Rack elevation diagram
2. Service dependency chart
3. Account relationship map
4. Application process flow

Correct Answer: 1

Explanation:

A rack elevation diagram represents the physical arrangement of equipment inside a server rack. It can show server positions, switches, power equipment, patch panels, and other hardware by rack-unit location. This documentation helps administrators quickly identify equipment during installation, maintenance, troubleshooting, and replacement activities. A service dependency chart shows relationships between software services, an account relationship map represents identity relationships, and an application process flow illustrates software operations. Keeping rack documentation accurate reduces confusion during maintenance and helps administrators locate equipment without unnecessarily disturbing unrelated systems.

Question 119.

Which storage model organizes information as objects rather than traditional hierarchical files?

1. Object-based storage
2. Sequential tape storage
3. Optical cartridge storage
4. Direct disk attachment

Correct Answer: 1

Explanation:

Object-based storage organizes information into objects that typically contain data, metadata, and a unique identifier. Unlike traditional filesystems, object storage does not primarily depend on hierarchical directories for data organization. It is well suited to large-scale repositories such as archives, media collections, backups, and cloud-oriented workloads. Sequential tape storage is designed around removable tape media, optical cartridge storage uses optical media, and direct disk attachment provides locally connected storage. Object storage can scale efficiently for large datasets when applications are designed to access information through object-based interfaces.

Question 120.

Which change-management practice defines how to return a server to its previous state after a failed change?

1. Rollback procedure
2. Asset inventory
3. Capacity projection
4. Maintenance checklist

Correct Answer: 1

Explanation:

A rollback procedure defines the steps required to return a server or service to its previous known-good condition when a change causes unexpected problems. It may involve restoring configuration files, reversing software updates, recovering a snapshot, or applying another documented recovery method. An asset inventory identifies equipment and resources, capacity projection estimates future requirements, and a maintenance checklist organizes routine activities. A rollback procedure should be prepared before significant changes are implemented and should be practical enough to execute quickly if the change produces service disruption or unexpected behavior.
