質問 # 534
A technician is investigating why a PC cannot reach a file server with the IP address 192.168.8.129. Given the following TCP/IP network configuration:

Which of the following configurations on the PC is incorrect?

A. IPv4 address
B. Default gateway
C. Subnet mask
D. IPv6 address

正解：B

解説：
Explanation
The default gateway is the IP address of the router that connects the PC to other networks. The default gateway should be on the same subnet as the PC's IPv4 address. However, in this case, the default gateway is
192.168.9.1, which is on a different subnet than the PC's IPv4 address of 192.168.8.15. Therefore, the default gateway configuration on the PC is incorrect and prevents the PC from reaching the file server on another subnet.

質問 # 535
A network engineer configured new firewalls with the correct configuration to be deployed to each remote branch. Unneeded services were disabled, and all firewall rules were applied successfully. Which of the following should the network engineer perform NEXT to ensure all the firewalls are hardened successfully?

A. Ensure an implicit permit rule is enabled
B. Use the same complex passwords on all firewalls
C. Configure the log settings on the firewalls to the central syslog server
D. Update the firewalls with current firmware and software

正解：D

解説：
Explanation
Updating the firewalls with current firmware and software is an important step to ensure all the firewalls are hardened successfully, as it can fix any known vulnerabilities or bugs and provide new features or enhancements. Enabling an implicit permit rule is not a good practice for firewall hardening, as it can allow unwanted traffic to pass through the firewall. Configuring the log settings on the firewalls to the central syslog server is a good practice for monitoring and auditing purposes, but it does not harden the firewalls themselves.
Using the same complex passwords on all firewalls is not a good practice for password security, as it can increase the risk of compromise if one firewall is breached. References: CompTIA Network+ Certification Exam Objectives Version 2.0 (Exam Number: N10-006), Domain 3.0 Network Security, Objective 3.3 Given a scenario, implement network hardening techniques.

質問 # 536
A network manager wants to view network traffic for devices connected to a switch. A network engineer connects an appliance to a free port on the switch and needs to configure the switch port connected to the appliance. Which of the following is the best option for the engineer to enable?

A. Trunking
B. SNMP
C. Port mirroring
D. Full duplex

正解：C

質問 # 537

C. Password complexity
D. Secure SNMP

正解：A

質問 # 538
A firewall administrator is implementing a rule that directs HTTP traffic to an internal server listening on a non-standard socket Which of the following types of rules is the administrator implementing?

A. STP
B. ARP
C. NAT
D. PAT
E. SNAT

正解：D

解説：
The firewall administrator is implementing a PAT (Port Address Translation) rule that directs HTTP traffic to an internal server listening on a non-standard socket. PAT is a type of NAT (Network Address Translation) that allows multiple devices to share a single public IP address by using different port numbers. PAT can also be used to redirect traffic from one port to another port on the same or different IP address. This can be useful for security or load balancing purposes. For example, a firewall administrator can configure a PAT rule that redirects HTTP traffic (port 80) from the public IP address of the firewall to an internal server that listens on a non-standard port (such as 8080) on its private IP address.

質問 # 539
A network technician was troubleshooting an issue for a user who was being directed to cloned websites that were stealing credentials. The URLs were correct for the websites but an incorrect IP address was revealed when the technician used ping on the user's PC After checking the is setting, the technician found the DNS server address was incorrect Which of the following describes the issue?

A. Exhausted IP scope
B. DNS poisoning
C. Misconfigured HSRP
D. Rogue DHCP server

正解：B

解説：
DNS poisoning is a type of attack that modifies the DNS records of a domain name to point to a malicious IP address instead of the legitimate one. This can result in users being directed to cloned websites that are stealing credentials, even if they enter the correct URL for the website. The incorrect DNS server address on the user's PC could be a sign of DNS poisoning, as the attacker could have compromised the DNS server or spoofed its response to redirect the user's queries.

C. Site-to-site VPN
D. Client-to-site VPN

正解：A

解説：
SSL is a widely used protocol for establishing secure, encrypted connections between devices over the Internet. It is typically used to secure communication between web browsers and servers, and can be easily enabled on a server by installing an SSL certificate.

質問 # 542
Which of the following is an example of on-demand scalable hardware that is typically housed in the vendor's data center?

A. DaaS
B. PaaS
C. SaaS
D. IaaS

正解：D

解説：
* IaaS (Infrastructure as a Service) is a cloud computing model that provides on-demand scalable hardware resources, such as servers, storage, network, and virtualization, that are typically housed in the vendor's data center12.
* IaaS allows customers to pay only for the resources they use, and to scale up or down as needed, without having to invest in or maintain their own physical infrastructure12.
* IaaS is different from other cloud computing models, such as DaaS (Desktop as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service), which provide different levels of abstraction and functionality12.
* DaaS delivers virtual desktops to users over the internet, allowing them to access their applications and data from any device3.
* PaaS provides a platform for developing, testing, and deploying applications, without having to manage the underlying infrastructure or software.
* SaaS delivers software applications over the internet, without requiring installation or maintenance on the user's device. References:

質問 # 543
Due to concerns around single points of failure, a company decided to add an additional WAN to the network. The company added a second MPLS vendor to the current MPLS WAN and deployed an additional WAN router at each site. Both MPLS providers use OSPF on the WAN network, and EIGRP is run internally. The first site to go live with the new WAN is successful, but when the second site is activated significant network issues occur. Which of the following is the MOST likely cause for the WAN instability?

A. A routing loop
B. An incorrect IP address
C. A switching loop
D. Asymmetrical routing

正解：D

解説：
Asymmetrical routing is the most likely cause for the WAN instability. When two different routing protocols are used, like OSPF and EIGRP, it can cause asymmetrical routing, which results in traffic being routed differently in each direction. This can lead to instability in the WAN. A CDP neighbor change, a switching loop, or an incorrect IP address are not likely causes for WAN instability.

質問 # 544

質問 # 549
A network technician receives a support ticket about an employee who has misplaced a company-owned cell phone that contains private company information. Which of the following actions should the network technician take to prevent data loss?

A. Turn off the service.
B. Lock the phone.
C. Execute remote wipe.
D. Disable the user account.

正解：C

解説：
Explanation
The best action for the network technician to take to prevent data loss in this scenario would be to execute a remote wipe on the lost cell phone. A remote wipe is a feature that allows the administrator to erase all the data from a device remotely. This will erase all the private company information from the lost phone, preventing it from falling into the wrong hands.
Other actions such as disabling the user account, locking the phone and turning off the service may not effectively prevent data loss. Disabling the user account will prevent the employee from accessing company resources, but it does not erase the data on the phone. Locking the phone may prevent unauthorized access, but it does not erase the data. Turning off the service may prevent the phone from connecting to the network, but it also does not erase the data.
