NEW QUESTION # 60
A user cannot access an external server for a client after connecting to a VPN. Which of the following commands would a support agent most likely use to examine the issue? (Select two).
Answer: B,C
Explanation:
When a user connects to a VPN and experiences connectivity issues to an external server, the problem is often related to routing or network path issues.
E:tracert:
Traces the path packets take from the user's device to the destination server.
Helps determine if the traffic is being blocked or misrouted.
F:route print:
Displays the device's routing table.
Helps diagnose whether traffic is being sent to the VPN tunnel instead of the correct external server.
Incorrect Options:
A:nslookup: Used for resolving domain names to IPs (DNS troubleshooting), but this issue is likely routing- related.
B:tcpdump: Captures packets for deep packet analysis, not typically the first step in diagnosing a VPN- related access issue.
C:arp: Used for resolving local network MAC addresses, not relevant for external VPN issues.
D:dig: Like nslookup, used for DNS queries, but not useful for routing problems.
NEW QUESTION # 61
Which of the following is a major difference between an IPS and IDS?
Answer: D
Explanation:
The key difference is that an Intrusion Prevention System (IPS) is installed in line with network traffic, allowing it to actively block threats. In contrast, an Intrusion Detection System (IDS) only monitors and alerts without actively blocking traffic.
Breakdown of Options:
A . An IPS needs to be installed in line with traffic and an IDS does not. โ
Correct answer. IPS actively prevents threats, while IDS only detects them.
B . An IPS is signature-based and an IDS is not. - False, both can use signature-based detection.
C . An IPS is less susceptible to false positives than an IDS. - False, both can produce false positives, depending on configurations.
D . An IPS requires less administrative overhead than an IDS. - False, IPS requires more administrative effort due to real-time blocking decisions.

NEW QUESTION # 62
After installing a new wireless access point, an engineer tests the device and sees that it is not performing at the rated speeds. Which of the following should the engineer do to troubleshoot the issue? (Select two.)
Answer: A,D
Explanation:
Troubleshooting poor performance of a newly installed access point involves multiple steps. Checking for network bottlenecks and ensuring the device firmware is up to date are crucial first steps. The document confirms:"Network bottlenecks can severely limit the performance of even the fastest wireless access points, so it's essential to verify that no other devices are causing a slowdown. In addition, keeping firmware updated ensures optimal performance and security."
NEW QUESTION # 63
As part of an attack, a threat actor purposefully overflows the content-addressable memory (CAM) table on a switch. Which of the following types of attacks is this scenario an example of?
Answer: D
Explanation:
* Definition of MAC Flooding:
* MAC flooding is an attack where a malicious actor sends numerous fake MAC addresses to a switch, overwhelming its CAM table. The CAM table stores MAC addresses and their associated ports for efficient traffic forwarding.
* Impact of MAC Flooding:
* CAM Table Overflow:When the CAM table is full, the switch cannot learn new MAC addresses and is forced to broadcast traffic to all ports, leading to a degraded network performance and potential data interception.
* Switch Behavior:The switch operates in a fail-open mode, treating the network as a hub, which can be exploited for eavesdropping on traffic.
* Comparison with Other Attacks:
* ARP Spoofing:Involves sending false ARP (Address Resolution Protocol) messages to associate the attacker's MAC address with the IP address of another device.
* Evil Twin:Involves creating a rogue wireless access point that mimics a legitimate one to intercept data.
* DNS Poisoning:Involves corrupting the DNS cache with false information to redirect traffic to malicious sites.
* Preventive Measures:
* Port Security:Configure port security on switches to limit the number of MAC addresses per port, preventing CAM table overflow.
* Network Segmentation:Use VLANs to segment network traffic and limit the impact of such attacks.

* CompTIA Network+ study materials on network security threats and mitigation techniques.
NEW QUESTION # 64
A network administrator suspects users are being sent to malware sites that are posing as legitimate sites. The network administrator investigates and discovers that user workstations are configured with incorrect DNS IP addresses. Which of the following should the network administrator implement to prevent this from happening again?
Answer: C
Explanation:
DHCP snooping is a security feature on network switches that helps to prevent unauthorized (rogue) DHCP servers from assigning IP addresses to clients. By implementing DHCP snooping, the network administrator can restrict DHCP responses to authorized servers only, preventing unauthorized DHCP configurations, such as incorrect DNS IPs, from being assigned to clients. This helps prevent man-in- the-middle attacks where malicious actors misconfigure DNS to redirect users to fraudulent sites.
