CompTIA SK0-005 Practice Test - Questions Answers, Page 44

Scenario:Installing Windows on an 8TB drive, aiming for a single 8TB partition.

Solution:Use theGPT (GUID Partition Table)option (Option C):

GPT supports larger partitions (up to 18.4 million TB) compared to MBR (limited to 2TB).

VMFS, ZFS, and LVM are unrelated to the partitioning scheme in Windows.

Lock Type:The type of lock utilizing key fobs or key cards is anelectronic door lock(Option C).

Electronic locks use electronic credentials (such as key cards) for access control.

Off-site storage involves storing data backups in a physically separate location from where the servers and primary data reside. This protects critical data in case the main site is damaged or destroyed due to a natural disaster, such as floods, fires, or earthquakes. Off-site storage can be in the form of cloud storage or physical tapes stored in a geographically distant location.

Off-site storage (Answer A): It ensures that a company's critical data remains accessible even if the local infrastructure is compromised. This is a common part of disaster recovery planning and is crucial for business continuity.

Life-cycle management (Option B): While important for managing data from creation to deletion, it does not specifically protect data during disasters.

Environmental controls (Option C): These manage physical conditions like temperature and humidity but do not address the risk of data loss during disasters.

Data-at-rest encryption (Option D): Encryption protects the confidentiality of stored data but does not ensure availability in the event of a disaster.

Enabling a UEFI (Unified Extensible Firmware Interface) password prevents unauthorized users from making changes to the server's hardware configuration settings, such as boot order or device settings. This is crucial for protecting the integrity of the server at a remote location where physical security might be more difficult to enforce.

UEFI password (Answer B): It provides security at the firmware level, preventing changes to low-level configurations unless the correct password is provided.

Administrator account (Option A): While important for OS-level access, it doesn't prevent someone with physical access from altering hardware settings via UEFI/BIOS.

Disabling WOL (Option C): Wake-on-LAN (WOL) allows a device to be powered on remotely. Disabling it can help with security but does not prevent hardware configuration changes.

Encryption at rest (Option D): Encryption protects data on the server but does not prevent hardware configuration access.

A misconfigured NTP (Network Time Protocol) on the client side can cause authentication issues because Active Directory relies on accurate time synchronization between clients and domain controllers for security purposes. If the clocks are out of sync, even by a few minutes, it can prevent users from authenticating to the domain.

NTP misconfiguration (Answer B): If the client machines have incorrect time settings, it can disrupt Kerberos-based authentication, which is time-sensitive.

Locked user accounts (Option A): While it can prevent login, it would affect individual users rather than a whole office.

MFA (Option C): Multi-factor authentication not working would typically cause a login issue but is less likely across an entire remote office.

Wrong time zone (Option D): While incorrect time zones can cause confusion, they usually don't prevent logins as long as the NTP server synchronizes the actual time correctly.

Since port 3306 (MySQL) is open on the local workstation as confirmed by the Nmap scan, the next logical step is to check network firewall rules. It's possible that the workstation's firewall or network-level security rules are blocking outbound or inbound traffic on port 3306, which is required for database access.

Edit the network firewall rules (Answer D): Ensuring the firewall allows traffic on port 3306 is the appropriate next step, especially since other workstations are not having the same issue.

Checking the database server (Option A): This is unnecessary because other workstations can access the server, confirming the server itself is functioning correctly.

Changing the database password (Option B): This would not resolve the issue of one workstation being unable to connect while others can.

Opening port 3306 on the server (Option C): The problem isn't server-side since other machines can connect without issue.

The server is shutting down after being powered on, which could indicate overheating. This is a common issue when fans fail, causing the CPU or other components to overheat and forcing the system to shut down to protect itself from damage.

Check for fan failure (Answer B): Ensuring the server's cooling system is functioning properly is crucial. Overheating due to a fan failure can cause the system to shut down automatically.

Resetting memory modules (Option A): While memory issues can cause system instability, they generally do not lead to immediate shutdowns as described.

Changing the VM password (Option C): This is unrelated to the shutdown issue.

Setting credentials for the remote console (Option D): This is irrelevant to the described problem of server shutdown.

In an active-passive load balancing configuration, 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 a heartbeat mechanism, 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.

A sniffer (also known as a packet analyzer) is a tool that captures and inspects data packets traveling across the network. In this case, using a sniffer would help identify suspicious or malicious redirection of traffic, possibly caused by a man-in-the-middle attack, DNS hijacking, or malware.

Sniffer (Answer D): This tool will allow the senior administrator to inspect the network traffic and identify if and how requests to the anti-malware website are being intercepted or redirected.

Data loss prevention (Option A): DLP tools focus on preventing data leakage rather than analyzing traffic redirection.

File integrity monitor (Option B): This checks for unauthorized changes to files, which may not directly address network traffic redirection.

Port scanner (Option C): A port scanner would only identify open ports on devices, which is unrelated to the redirection issue.
