CompTIA SK0-005 - CompTIA Server+ Certification Exam

The first step when addressing an urgent issue like a database disconnection should be to gather information to understand what actions caused the problem.Collecting all logs and reviewing the technician's actions (Answer D)will help identify what went wrong and guide appropriate remediation. Restoring access quickly is the priority, and without reviewing logs, it would be hard to identify the root cause or prevent further damage.

Reverting patches (Option A):Reverting patches might cause more issues if the problem isn't directly related to a recent update.

Reproducing the issue (Option B):Reproduction is useful in a controlled environment but not practical as an immediate first step in production.

Root cause analysis (Option C):This is necessary but should come after restoring access.

Performing a quick backup (Option E):While backups are crucial, this step might not help resolve the current access problem and can delay troubleshooting.

CompTIA Server+ Reference:This topic relates toSK0-005 Objective 3.4: Explain troubleshooting theory and methodologies.

In anactive-passive load balancingconfiguration, one path (or server) handles all the traffic while the other remains in standby mode, ready to take over if the active path becomes unavailable. This setup is typically monitored via aheartbeatmechanism, where the standby server checks the availability of the active server and takes over when it detects a failure.

Heartbeat (Answer B):This term refers to the monitoring process that checks the availability of the active path in an active-passive configuration.

Most recently used (Option A):This describes a load-balancing method where the most recently used path or server is prioritized, but it doesn’t describe an active-passive setup.

Link aggregation (Option C):This refers to combining multiple network connections for increased throughput, not for failover purposes.

Round robin (Option D):This load-balancing method alternates traffic between all available paths, which doesn’t match the active-passive description.

CompTIA Server+ Reference:This topic is covered underSK0-005 Objective 1.4: Summarize methods used to manage network connections.

Port 443 is used for HTTPS, which is a secure version of HTTP that encrypts the data between the web server and the client. Port 3389 is used for RDP, which is a protocol that allows remote desktop connections to a server. These ports should be allowed for a secure web server that can be administered via RDP.

 Application consistent backup is a method of backing up data that ensures the integrity and consistency of the application state. It involves notifying the application to flush its data from memory to disk and quiescing any write operations before taking a snapshot of the data. If the databases were not backed up to be application consistent, they might contain incomplete or corrupted data that cannot be restored properly.

The first thing the administrator should check is whether the server is in the collection that was scheduled to receive the update through SCCM. A collection is a group of resources, such as computers or users, that can be managed as a single entity bySCCM. If the server is not in the collection, it will not receive the update. The other options are less likely to be the cause of the problem, as they would affect other aspects of the server’s functionality besides receiving updates. References: CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.4: Given a scenario, apply patches/updates and validate their installation.

HIDS (Host Intrusion Detection System): Continuously monitors a system for suspicious activity and logs or raises alerts when potential threats are identified. This proactive approach is crucial for identifying and mitigating threats on a web server exposed to the external network.

Applying OS updates: While essential for maintaining system security, updates address vulnerabilities and may not necessarily identify ongoing threats.

Disabling unused services: Reduces the attack surface by minimizing potential entry points for malicious actors, but doesn't actively identify threats.

Installing anti-malware: Primarily designed to detect and remove malware after infection, not for ongoing threat identification.

A rescan on the server’s RAID controller is a possible troubleshooting step to detect the existing RAID configurations on the connected storage arrays. A firmware upgrade may cause the RAID controller to lose the RAID metadata or settings, and a rescan may restore them. A rescan is preferable to restoring the default RAID configuration, as the latter may erase the existing data on the arrays. Power cycling the storage arrays or booting the OS into recovery mode may not help if the RAID controller does not recognize the RAID sets.

The most important piece of information needed by the legal department in the event that an employee does not return company-issued equipment is the asset tag. The asset tag is a unique identifier that is used to track assets throughout their lifecycle. It allows the company to keep precise records of the assets, monitor their location, and manage their overall inventory. In legal situations, the asset tag can be used to prove ownership and aid in the recovery process of the equipment. The serial number is also important, but it is the asset tag that ties the equipment directly to the company's asset management system and is therefore the most crucial for the legal department. Warranty and labeling information are less critical from a legal perspective when it comes to unreturned equipment.

The most likely cause of the issue is that the server has not been joined to the domain. A domain is a logical group of computers and devices that share a common directory service and security policy. A domain controller is a server that manages the domain and authenticates users and computers that want to access domain resources. To log on with domain credentials, a server must be joined to the domain and registered in the directory service. If a server has not been joined to the domain, it will not be recognized or authorized by the domain controller.

An emergency change request is a type of change request that is initiated in response to an urgent situation, such as a system breach, that requires immediate action to restore normal operations or prevent further damage. An emergency change request may bypass some of the normal change management procedures, such as approval, testing, or documentation, in order to expedite the implementation of the change. However, an emergency change request should still follow the basic steps of change management, such as identification, analysis, planning, execution, and evaluation, and should be reviewed and documented after the change is completed.
