NEW QUESTION # 231
A company is hosting a secure that requires all connections to the server to be encrypted. A junior administrator needs to harded the web server. The following ports on the web server. The following ports on the web server are open:
Which of the following ports should be disabled?
Answer: C
Explanation:
For a web server that requires all connections to be encrypted, port 80 (HTTP) should be disabled. Port 80 is used for unencrypted web traffic, whereas port 443 is used for HTTPS, which provides encrypted communication.
* Port 80 (HTTP): This port is used for unsecured web traffic. Disabling this port ensures that all web traffic must use HTTPS, which encrypts the data in transit.
* Port 443 (HTTPS): This port is used for secure web traffic via SSL/TLS encryption. Keeping this port open ensures that secure connections can be made to the web server.
* Other Ports:
* Port 22: Used for SSH, providing secure remote access and file transfers.
* Port 587: Used for secure email submission (SMTP) with encryption.
Network References:
* CompTIA Network+ N10-007 Official Certification Guide: Discusses the roles and security implications of various ports and protocols.
* Cisco Networking Academy: Provides training on secure web server configuration and port management.
* Network+ Certification All-in-One Exam Guide: Covers port security and best practices for securing web servers.
NEW QUESTION # 232
Which of the following allows the fastest recovery during a catastrophe event?
Answer: B
Explanation:
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.
NEW QUESTION # 233
Which of the following connection methods allows a network engineer to automate configuration deployment for network devices across the environment?
Answer: B
Explanation:
Comprehensive and Detailed Explanation (paraphrased, aligned to N10-009):
SSH provides secure, scriptable remote access used by automation/orchestration tools (e.g., leveraging CLI, NETCONF over SSH, or Ansible modules) to push configurations at scale.
* A. RDP is primarily for Windows GUI sessions and is not commonly used for network device automation.
* B. Telnet can be scripted but is insecure (plaintext); modern best practice is to use SSH.
* D. GUI access is typically manual and not ideal for scalable, repeatable automation.
References (CompTIA Network+ N10-009):
* Domain: Network Operations - Configuration management, automation/orchestration, secure management protocols (SSH vs. Telnet), change at scale.
NEW QUESTION # 234
A network technician replaced an access layer switch and needs to reconfigure it to allow the connected devices to connect to the correct networks.
INSTRUCTIONS
Click on the appropriate port(s) on Switch 1 and Switch 3 to verify or reconfigure the correct settings:
Ensure each device accesses only its
correctly associated network.
Disable all unused switchports.
. Require fault-tolerant connections
between the switches.
. Only make necessary changes to
complete the above requirements.
Answer:
Explanation:
See the solution below in Explanation.
Explanation:
To provide a complete solution for configuring the access layer switches, let's proceed with the following steps:
* Identify the correct VLANs for each device and port.
* Enable necessary ports and disable unused ports.
* Configure fault-tolerant connections between the switches.
Port 1 Configuration (Uplink to Core Switch)
* Status: Enabled
* LACP: Enabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Tagged for VLAN60, VLAN90, VLAN120, VLAN150, VLAN220 Port 2 Configuration (Uplink to Core Switch)
* Status: Enabled
* LACP: Enabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Tagged for VLAN60, VLAN90, VLAN120, VLAN150, VLAN220 Port 3 Configuration (Server Connection)
* Status: Enabled
* LACP: Disabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Untagged for VLAN90 (Servers)
Port 4 Configuration (Server Connection)
* Status: Enabled
* LACP: Disabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Untagged for VLAN90 (Servers)
Port 5 Configuration (Wired Users and WLAN)
* Status: Enabled
* LACP: Enabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Tagged for VLAN60, VLAN120, VLAN150
Port 6 Configuration (Wired Users and WLAN)
* Status: Enabled
* LACP: Enabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Tagged for VLAN60, VLAN120, VLAN150
Port 7 Configuration (Voice and Wired Users)
* Status: Enabled
* LACP: Enabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Tagged for VLAN60, VLAN90, VLAN120, VLAN220
Port 8 Configuration (Voice, Printers, and Wired Users)
* Status: Enabled
* LACP: Enabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Tagged for VLAN60, VLAN90, VLAN120, VLAN220
Port 1 Configuration (Unused)
* Status: Disabled
* LACP: Disabled
Port 2 Configuration (Unused)
* Status: Disabled
* LACP: Disabled
Port 3 Configuration (Connection to Device)
* Status: Enabled
* LACP: Disabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Untagged for VLAN1 (Default)
Port 4 Configuration (Connection to Device)
* Status: Enabled
* LACP: Disabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Untagged for VLAN1 (Default)
Port 5 Configuration (Connection to Device)
* Status: Enabled
* LACP: Disabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Untagged for VLAN1 (Default)
Port 6 Configuration (Connection to Device)
* Status: Enabled
* LACP: Disabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Untagged for VLAN1 (Default)
Port 7 Configuration (Connection to Device)
* Status: Enabled
* LACP: Disabled
* Speed: 1000
* Duplex: Full
* VLAN Configuration: Untagged for VLAN1 (Default)
* Ports 1 and 2 on Switch 1 are configured as trunk ports with VLAN tagging enabled for all necessary VLANs.
* Ports 3 and 4 on Switch 1 are configured for server connections with VLAN 90 untagged.
* Ports 5, 6, 7, and 8 on Switch 1 are configured for devices needing access to multiple VLANs.
* Unused ports on Switch 3 are disabled.
* Ports 3, 4, 5, 6, and 7 on Switch 3 are enabled for default VLAN1.
* Core Switch Ports should be configured as needed for uplinks to Switch 1.
* Ensure LACP is enabled for redundancy on trunk ports between switches.
By following these configurations, each device will access only its correctly associated network, unused switch ports will be disabled, and fault-tolerant connections will be established between the switches.
NEW QUESTION # 235
A server administrator deploys a new web server with an IP address of 192.168.16.100. The security policy dictates that all non-secure connection methods should be blocked. Which of the following security rules will satisfy the request without prohibiting other traffic?
Answer: D
Explanation:
Denying TCP port 80 specifically for 192.168.16.100 blocks unencrypted HTTP while permitting all other traffic - including HTTPS on port 443 - so secure connections remain allowed.
