After removing the virus from the server, the administrator should perform the following actions to mitigate the issue from reoccurring and to maintain high availability:

Run a vulnerability scanner on the server to identify any other potential weaknesses or exposures that could be exploited by attackers.

Patch the vulnerability that allowed the virus to infect the server in the first place, using the latest updates from the database software vendor or a trusted source.

Update the antivirus software on the server to ensure it has the most recent virus definitions and can detect and prevent future infections. The other options are either unnecessary or counterproductive for this scenario. Repartitioning the hard drive, reformatting the OS, removing the database software, or air gapping the server from the network would cause downtime and data loss, while enabling a host firewall would not prevent a virus infection from within the network. References: CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.2: Given a scenario involving a security threat/vulnerability/risk, implement appropriate mitigation techniques.

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.

Uplink redundancy is a method used to ensure that if one physical network interface card (NIC) fails, the network connectivity for the virtual machines (VMs) does not go down. This is typically achieved by configuring multiple NICs to connect to a single virtual switch (vSwitch) and setting up NIC teaming or bonding. The vSwitch manages the internal network traffic between the VMs and the outside network by using the physical NICs assigned to it. By configuring the vSwitch with multiple NICs, you can create redundancy, so if one NIC fails, the other NICs can take over the traffic, ensuring continuous network connectivity.

A CMOS battery failure can cause the server to lose its BIOS settings, including the date and time, which can affect the server’s functionality and connectivity. The servers have NTP (Network Time Protocol) configured to synchronize their clocks with a reliable time source, which can prevent time drift and ensure consistent timestamps. If one server has a wrong date and time, it can cause conflicts and errors with the other servers that have NTP configured.
