問題 #575
Which of the following allows the fastest recovery during a catastrophe event?
答案：A
解題說明：
The correct answer is D. Hot site. In CompTIA Network+ N10-009, disaster recovery and business continuity concepts include understanding recovery site types and how quickly they can restore operations after a major outage or catastrophe. A hot site provides the fastest recovery because it is a fully operational alternate location with the necessary network infrastructure, hardware, systems, connectivity, and often replicated data already available. Since the environment is prepared and ready to assume production workloads, organizations can fail over to a hot site with minimal downtime.
A warm site is partially prepared and may have network connectivity and some hardware in place, but it usually requires additional configuration, data restoration, or system activation before services can fully resume. A cold site provides only basic facilities, such as space, power, and cooling, but lacks most operational equipment and therefore has the longest recovery time. Asynchronous replication is a data replication method where changes are copied after they occur, but it is not itself a complete recovery location and may involve some data loss depending on timing.
Because the question asks which option allows the fastest recovery during a catastrophe, the best choice is a hot site.
問題 #576
A network administrator is configuring a new switch and wants to ensure that only assigned devices can connect to the switch. Which of the following should the administrator do?
答案：C
問題 #577
A network administrator needs to set up a multicast network for audio and video broadcasting. Which of the following networks would be the most appropriate for this application?
答案：B
解題說明：
* Understanding Multicast:
* Multicast IP Address Range:The multicast address range is from 224.0.0.0 to 239.255.255.255, designated for multicast traffic.
* Multicast Applications:
* Use Case:Multicast is used for one-to-many or many-to-many communication, suitable for applications like audio and video broadcasting where the same data is sent to multiple recipients simultaneously.
* Appropriate Network Selection:
* 224.0.0.0/24 Network:This range is reserved for multicast addresses, making it the appropriate choice for setting up a multicast network.
* Comparison with Other Options:
* 172.16.0.0/24:Part of the private IP address space, used for private networks, not designated for multicast.
* 192.168.0.0/24:Another private IP address range, also not for multicast.
* 240.0.0.0/24:Reserved for future use, not suitable for multicast.
References:
* CompTIA Network+ study materials on IP address ranges and multicast.
問題 #578
A virtual machine has the following configuration:
*IPv4 address: 169.254.10.10
*Subnet mask: 255.255.0.0
The virtual machine can reach colocated systems but cannot reach external addresses on the Internet. Which of the following Is most likely the root cause?
答案：C
解題說明：
* Understanding the 169.254.x.x Address:
* An IPv4 address in the range of 169.254.x.x is an Automatic Private IP Addressing (APIPA) address, assigned when a DHCP server is unavailable.
* DHCP Server Offline:
* APIPA Assignment: When a device cannot obtain an IP address from a DHCP server, it assigns itself an APIPA address to enable local network communication. This allows communication with other devices on the same local subnet but not with external networks.
* Resolution: Ensure the DHCP server is operational. Check for connectivity issues between the virtual machine and the DHCP server, and verify the DHCP server settings.
* Comparison with Other Options:
* The subnet mask is incorrect: The subnet mask 255.255.0.0 is appropriate for the 169.254.x.x range and does not prevent external access by itself.
* The IP address is an RFC1918 private address: RFC1918 addresses are private IP ranges (10.x.
x.x, 172.16.x.x-172.31.x.x, 192.168.x.x) but 169.254.x.x is not one of them.
* The DNS server is unreachable: While this could affect name resolution, it would not prevent the assignment of a non-APIPA address or local network communication.
* Troubleshooting Steps:
* Verify the DHCP server's status and connectivity.
* Restart the DHCP service if necessary.
* Renew the IP lease on the virtual machine using commands such as ipconfig /renew (Windows) or dhclient (Linux).

* CompTIA Network+ study materials on IP addressing and DHCP troubleshooting.
問題 #579
A network administrator is implementing security zones for each department. Which of the following should the administrator use to accomplish this task?
答案：D
解題說明：
* Understanding ACLs:
* Access Control Lists (ACLs): A set of rules used to control network traffic and restrict access to network resources by filtering packets based on IP addresses, protocols, or ports.
* Implementing Security Zones:
* Defining Zones: ACLs can be used to create security zones by applying specific rules to different departments, ensuring that only authorized traffic is allowed between these zones.
* Control Traffic: ACLs control inbound and outbound traffic at network boundaries, enforcing security policies and preventing unauthorized access.
* Comparison with Other Options:
* Port Security: Limits the number of devices that can connect to a switch port, preventing MAC address flooding attacks, but not used for defining security zones.
* Content Filtering: Blocks or allows access to specific content based on predefined policies, typically used for web filtering rather than network segmentation.
* NAC (Network Access Control): Controls access to the network based on the security posture of devices but does not define security zones.
* Implementation Steps:
* Define ACL rules based on the requirements of each department.
* Apply these rules to the appropriate network interfaces or firewall policies to segment the network into security zones.
