問題 #791
Which of the following is the part of a DR plan that identifies the critical systems that should be recovered first after an incident?

答案：D

解題說明：
The Recovery Time Objective specifies how quickly each critical system must be back online after an incident, effectively ranking them so those with the shortest RTOs are recovered first.


問題 #792
A network engineer configures a new switch and connects it to an existing switch for expansion and redundancy. Users immediately lose connectivity to the network. The network engineer notes the following spanning tree information from both switches:
Switch 1
Port State Cost
1 Forward 2
2 Forward 2
Switch 2
Port State Cost
1 Forward 2
2 Forward 2
Which of the following best describes the issue?

答案：C

解題說明：
The issue is that no root bridge has been identified. In STP, a root bridge is necessary to manage redundant paths and avoid loops in the network. Without a root bridge, all switches will assume they can forward traffic, causing a network loop and connectivity problems.
=


問題 #793
While troubleshooting connectivity issues, a junior network administrator is given explicit instructions to test the host's TCP/IP stack first. Which of the following commands should the network administrator run?

答案：C

解題說明：
The loopback address (127.0.0.1) is used to test a host's local TCP/IP stack, ensuring that the networking components of the operating system are functioning properly.
* This test does not require network connectivity because it only checks if the local machine's TCP/IP stack is operational.
* If the loopback test fails, it indicates a misconfigured TCP/IP stack, corrupt drivers, or an issue with the OS networking components.
* Option B (ping 169.254.1.1) - This is an APIPA (Automatic Private IP Addressing) address, which is assigned when DHCP fails. It does not test the local TCP/IP stack.
* Option C (ping 172.16.1.1) and Option D (ping 192.168.1.1) - These are private network addresses and test connectivity to other devices, not the local TCP/IP stack.

問題 #794
Users at an organization report that the wireless network is not working in some areas of the building. Users report that other wireless network SSIDs are visible when searching for the network, but the organization's network is not displayed. Which of the following is the most likely cause?

答案：D

解題說明：
If thecompany's SSID is not visiblein some areas while other networks are still visible, the most likely cause isinsufficient wireless coverage. The wireless signaldoes not reach those areas, meaning additional access points or signal boosters may be required.
Breakdown of Options:
* A. Interference or channel overlap- Would causeslow or unstable connections, but the SSID should still be visible.
* B. Insufficient wireless coverage-#Correct answer.If the SSID is not appearing, thesignal is too weakin that area.
* C. Roaming misconfiguration- Would causedevices to stay on weaker APsinstead of switching, but the SSID should still be visible.
* D. Client disassociation issues- This woulddisconnect users, but they shouldstill see the network.


問題 #795
Which of the following ports is used for secure email?

答案：B

解題說明：
Port 587 is used for secure email submission. This port is designated for message submission by mail clients to mail servers using the SMTP protocol, typically with STARTTLS for encryption.
* Port 25: Traditionally used for SMTP relay, but not secure and often blocked by ISPs for outgoing mail due to spam concerns.
* Port 110: Used for POP3 (Post Office Protocol version 3), not typically secured.
* Port 143: Used for IMAP (Internet Message Access Protocol), which can be secured with STARTTLS or SSL/TLS.
* Port 587: Specifically used for authenticated email submission (SMTP) with encryption, ensuring secure transmission of email from clients to servers.
Network References:
* CompTIA Network+ N10-007 Official Certification Guide: Discusses email protocols and ports, including secure email transmission.
* Cisco Networking Academy: Provides training on securing email communications and the use of appropriate ports.
* Network+ Certification All-in-One Exam Guide: Explains email protocols, ports, and security considerations for email transmission.
