CompTIA Server+ Certification Exam 認定 SK0-005 試験問題 (Q193-Q198):

質問 # 193
A server administrator is taking advantage of all the available bandwidth of the four NICs on the server.
Which of the following NIC-teaming technologies should the server administrator utilize?

A. Fail over
B. Load balancing
C. Fault tolerance
D. Link aggregation

正解：D

解説：
Explanation
Link aggregation is a technique that combines multiple physical network links into one logical link with higher bandwidth and redundancy. It can take advantage of all the available bandwidth of the NICs (Network Interface Cards) on the server and provide load balancing and failover capabilities for network traffic. Verified References: [Link aggregation], [NIC]

質問 # 194
A VLAN needs to be configured within a virtual environment for a new VM. Which of the following will ensure the VM receives a correct IP address?

A. A vNlC
B. A virtual switch
C. A VPN
D. A virtual router
E. A host NIC

正解：B

解説：
Explanation
The correct answer is D. A virtual switch.
A virtual switch is a software-based network device that connects the virtual machines (VMs) in a virtual environment and allows them to communicate with each other and with the physical network. A virtual switch can also create and manage virtual LANs (VLANs), which are logical segments of a network that separate the traffic of different VMs or groups of VMs. A VLAN needs a DHCP server to assign IP addresses to the VMs that belong to it. A virtual switch can act as a DHCP relay agent and forward the DHCP requests from the VMs to the DHCP server on the physical network.This way, the VMs can receive correct IP addresses for their VLANs123 A virtual router is a software-based network device that routes packets between different networks or subnets.
A virtual router can also create and manage VLANs, but it is not necessary for a VM to receive a correct IP address.A virtual router can be used to provide additional security, redundancy, or load balancing for the VMs12 A host NIC is a physical network interface card that connects the host machine to the physical network. A host NIC can also support VLAN tagging, which allows the host machine to communicate with different VLANs on the network. However, a host NIC alone cannot ensure that a VM receives a correct IP address for its VLAN.The host NIC needs to be connected to a virtual switch that can relay the DHCP requests from the VMs to the DHCP server12 A VPN is a virtual private network that creates a secure tunnel between two or more devices over the internet.
A VPN can be used to encrypt and protect the data traffic of the VMs, but it is not related to the configuration of VLANs or IP addresses.A VPN does not affect how a VM receives a correct IP address for its VLAN14 A vNIC is a virtual network interface card that connects a VM to a virtual switch or a virtual router. A vNIC can also support VLAN tagging, which allows the VM to communicate with different VLANs on the network.However, a vNIC alone cannot ensure that a VM receives a correct IP address for its VLAN.The vNIC needs to be connected to a virtual switch or a virtual router that can relay the DHCP requests from the VMs to the DHCP server12

質問 # 195
Which of the following technologies would allow an administrator to build a software RAID on a Windows server?

A. GPT
B. Logical volume management
C. Dynamic disk
D. UEFI

正解：C

解説：
Dynamic disk is a technology that allows an administrator to build a software RAID on a Windows server.
Dynamic disk is a type of disk management that supports creating volumes that span multiple disks, stripe data across disks, mirror data between disks, or use parity for fault tolerance. Dynamic disk can be used to create RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), or spanned volumes on Windows servers. Logical volume management is a technology that allows creating and resizing logical volumes on Linux servers. GPT (GUID Partition Table) is a standard for defining the partition structure on a disk. UEFI (Unified Extensible Firmware Interface) is a specification for the interface between the operating system and the firmware.

質問 # 196
IDS alerts indicate abnormal traffic patterns are coming from a specific server in a data center that hosts sensitive dat a. Upon further investigation, the server administrator notices this server has been infected with a virus due to an exploit of a known vulnerability from its database software. Which of the following should the administrator perform after removing the virus to mitigate this issue from reoccurring and to maintain high availability? (Select three).

A. Air gap the server from the network.
B. Repartition the hard drive that houses the database.
C. Run a vulnerability scanner on the server.
D. Remove the database software.
E. Update the antivirus software.
F. Reformat the OS on the server.
G. Patch the vulnerability.
H. Enable a host firewall.

正解：C、E、G

解説：
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.

質問 # 197
