NEW QUESTION # 355
Which of the following objectives does an evil twin achieve?
Answer: C
Explanation:
An evil twin attack is when an attacker sets up a rogue access point (AP) with the same SSID as a legitimate one to trick users into connecting. Once users connect, attackers often present fake login pages or capture unencrypted session data to steal login credentials.
A). DNS poisoning manipulates DNS resolution but is not inherent to evil twin.
C). ARP spoofing is a Layer 2 attack involving MAC/IP mapping manipulation.
D). Denial of service can be a side effect but is not the primary objective of evil twin attacks.
The main purpose of an evil twin is credential theft, enabling further unauthorized access to networks or systems.
References (CompTIA Network+ N10-009):
Domain: Network Security - Wireless attacks, rogue APs, evil twins.
NEW QUESTION # 356
Which of the following cable types allows the use of QSFP ports without requiring transceivers?
Answer: B
Explanation:
Twinaxial (Direct Attach Copper / DAC) cables can plug directly into QSFP ports without needing separate optical transceivers. They are cost-effective for short-distance, high-speed connections (commonly in data centers).
A). Multimode fiber requires SFP/QSFP transceivers to convert electrical signals to optical.
C). RG11 is coaxial cable for broadband/cable TV, not used in QSFP ports.
D). Category 6 is twisted-pair Ethernet cabling, not directly compatible with QSFP ports.

Domain: Network Infrastructure - Cable types, QSFP, DAC (Twinaxial), transceiver requirements.
NEW QUESTION # 357
Which of the following most likely requires the use of subinterfaces?
Answer: B
Explanation:
Introduction to Subinterfaces:
Subinterfaces are logical interfaces created on a single physical interface. They are used to enable a router to support multiple networks on a single physical interface.
Use Case for Subinterfaces:
Subinterfaces are commonly used in scenarios where VLANs are implemented. A router with a single physical LAN port can be configured with multiple subinterfaces, each associated with a different VLAN.
This setup allows the router to route traffic between different VLANs.
Example Configuration:
Consider a router with a single physical interface GigabitEthernet0/0 and two VLANs, 10 and 20.
interface GigabitEthernet0/0.10
encapsulation dot1Q 10
ip address 192.168.10.1 255.255.255.0
!
interface GigabitEthernet0/0.20
encapsulation dot1Q 20
ip address 192.168.20.1 255.255.255.0
The encapsulation dot1Q command specifies the VLAN ID.
Explanation of the Options:
A: A router with only one available LAN port: This is correct. Subinterfaces allow a single physical interface to manage multiple networks, making it essential for routers with limited physical interfaces.
B: A firewall performing deep packet inspection: Firewalls can use subinterfaces, but it is not a requirement for deep packet inspection.
C: A hub utilizing jumbo frames: Hubs do not use subinterfaces as they operate at Layer 1 and do not manage IP addressing.
D: A switch using Spanning Tree Protocol: STP is a protocol for preventing loops in a network and does not require subinterfaces.
Conclusion:
Subinterfaces provide a practical solution for routing between multiple VLANs on a router with limited physical interfaces. They allow network administrators to optimize the use of available hardware resources efficiently.

CompTIA Network+ guide detailing VLAN configurations and the use of subinterfaces (see page Ref
9 Basic Configuration Commands).
NEW QUESTION # 358
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: D,F
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 # 359
Which of the followingprotocolsis used toroute traffic on the public internet?
Answer: A
Explanation:
Comprehensive and Detailed Explanation:
Border Gateway Protocol (BGP)is theprimary protocolused toroute traffic on the public internet. It allows ISPs and large networks toexchange routing information, making it anExterior Gateway Protocol (EGP).
Breakdown of Options:
* A. BGP-Correct answer.Used forinternet routingand exchangesrouting information between ISPs.
* B. OSPF- AnInterior Gateway Protocol (IGP)used for routingwithinan autonomous system (not the public internet).
* C. EIGRP- Cisco's proprietaryIGP, usedwithinprivate networks, not the public internet.
* D. RIP- An olderdistance-vector protocol,not scalablefor the internet.
