SK0-005 Exam Dumps - CompTIA Server+ Certification Exam

NIC teaming is a feature that allows the use of multiple network interface cards (NICs) as a single logical interface with a single IP address. It can improve the network performance, bandwidth, and redundancy of a server. Verified References: [NIC teaming], [Network interface card]

A link aggregation group (LAG) is a technique that combines multiple physical network interfaces into a single logical interface. This allows for the distribution of traffic across all the interfaces in the group, increasing bandwidth and redundancy. A LAG can use different modes to balance the load, such as address hashing, dynamic, or most recently used algorithm.

The server administrator should close port 3389 and rerun the scan. Port 3389 is used for Remote Desktop Protocol (RDP), which allows remote access and control of a server. RDP is vulnerable to brute-force attacks, credential theft, and malware infection. Closing port 3389 can prevent unauthorized access and improve the security of the server. The other ports are not as risky as port 3389 and can be left open for legitimate purposes. References: CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.4: Given a scenario, implement proper environmental controls and techniques.

A warm site is a backup location that has partial infrastructure ready to support operations in the event of a failure at the primary site. It is almost ready to take over but requires some configuration or installation of data backups and software before it can become fully operational.

Warm site (Answer C): This site has the necessary equipment but requires some setup, making it a middle ground between cold and hot sites.

Basic technical facilities (Option A): This more accurately describes a cold site.

Faulty air conditioning (Option B): This is irrelevant to the definition of a warm site.

Fully operational (Option D): This describes a hot site, which is continuously ready to provide full services.

CompTIA Server+ Reference:This topic is related to SK0-005 Objective 4.1: Summarize disaster recovery methods and concepts.

Link Aggregation: Involves combining multiple physical network interfaces into a single logical interface. This creates increased bandwidth, improved fault tolerance, and load balancing, where traffic can be distributed across all links in the group. (CompTIA Server+ Objectives SK0-004: 2.4)

Why other options are incorrect:

Most recently used algorithm: A concept used in memory management, not network traffic distribution.

Active-passive configuration: Used for failover with only one interface active at a time.

Failover: Ensures service continuity if an interface fails but does not inherently distribute load across multiple links.

Updating the firmware on the NIC is the most likely solution to fix the issue of a new 40GB NIC not being detected within the Windows server OS. Firmware is a software program that controls the functionality of a hardware device, such as a NIC (network interface card). A NIC is a device that enables network communication for a server by providing an interface between the server and the network cable or wireless connection. Updating the firmware on the NIC can improve its performance, compatibility, and stability with the server OS and network protocols. References: CompTIA Server+ Certification Exam Objectives, Domain 4.0: Networking, Objective 4.1: Given a scenario, configure network settings for servers.

The Recovery Point Objective (RPO) refers to the maximum tolerable period in which data might be lost from an IT service due to a major incident. The policy mentioned in the question highlights that data loss exceeding one hour is unacceptable, directly relating to the RPO concept. RPO is critical in disaster recovery and business continuity planning, indicating the age of the files that must be recovered from backup storage for normal operations to resume without significant losses. MTTR (Mean Time To Repair), RTO (Recovery Time Objective), and MTBF (Mean Time Between Failures) are related concepts but do not specifically address the amount of data loss that can be tolerated.

A warm site is a backup site that has some of the necessary hardware, software, and network resources to resume operations, but not all of them. A warm site requires some time and effort to become fully operational. A warm site is different from a cold site, which has minimal or no resources, and a hot site, which has all the resources and is ready to take over immediately.
