1. Question 801 · 871 in bank

   Which of the following is the physical topology in which all devices are connected to each other?

   • ABus
   • BRing
   • CMesh
   • DStar

   Show answer

   Answer: C

   Explanation

   Mesh topology connects every device to every other device on the network. This provides high redundancy and reliability because there are multiple paths for data to travel between devices. If one connection fails, data can still be routed through other paths. In a bus topology, all devices are connected to a single central cable, known as the bus, and data is transmitted along this shared medium. A ring topology features devices connected in a circular fashion, with each device linking to two others to form a ring where data circulates until it reaches its destination. In a star topology, devices are connected to a central hub or switch, and all data passes through this central node, with no direct connections between devices themselves.

2. Question 802 · 871 in bank

   Which of the following most likely occurs when an attacker is between the target and a legitimate server?

   • AIP spoofing
   • BVLAN hopping
   • CRogue DHCP
   • DOn-path attack

   Show answer

   Answer: D

   Explanation

   An on-path attack (previously known as a man-in-the-middle attack) occurs when an attacker intercepts and potentially alters the communication between a client and a server. This attacker can eavesdrop, capture sensitive information, or inject malicious data into the communication stream. IP spoofing involves an attacker falsifying the source IP address of packets to appear as if they are coming from a trusted source, but it does not specifically indicate the attacker is between the target and server. VLAN hopping refers to an attack where an attacker sends traffic to VLANs they are not supposed to access by exploiting VLAN tagging, which is not related to intercepting or altering communication between a client and server. Rogue DHCP involves setting up a fake DHCP server to assign incorrect IP addresses or network configurations, leading to issues like network misdirection or denial of service, but it does not necessarily involve intercepting communication between a client and server directly.

3. Question 803 · 871 in bank

   A technician is troubleshooting an incident regarding a fiber that is connecting two buildings. The technician suspects a break may have occurred midway along the route. Which of the following tools should the technician use to verify the point where the break might be located?

   • ALoopback adapter
   • BOTDR
   • CCable tester
   • DNew SFPs

   Show answer

   Answer: B

   Explanation

   It was on my exam (April 25th, 2024). An 'Optical Time Domain Reflectometer' (OTDR) is a fiber optic testing device used for identifying fiber break points, measuring cable lengths, and calculating relative optical power losses.

5. Question 805 · 871 in bank

   A technician is configuring a bandwidth-monitoring tool that supports payloads of 1,600 bytes. Which of the following should the technician configure for this tool?

   • ALACP
   • BFlow control
   • CPort mirroring
   • DJumbo frames

   Show answer

   Answer: D

   Explanation

   Jumbo frames allow for larger Ethernet frames, accommodating payloads larger than the standard 1,500 bytes, such as the 1,600 bytes supported by the bandwidth-monitoring tool. Configuring jumbo frames ensures that the tool can handle and process larger payloads effectively. A. LACP (Link Aggregation Control Protocol): LACP is used to combine multiple physical network connections into a single logical link to increase bandwidth and provide redundancy, but it does not address payload size. B. Flow control: Flow control manages the rate of data transmission to prevent network congestion and data loss but does not impact the size of the payload that can be handled. C. Port mirroring: Port mirroring copies traffic from one port to another for monitoring and analysis purposes but does not affect the configuration of frame sizes or payload capacities.

6. Question 806 · 871 in bank

   Which of the following would need to be configured to ensure a device with a specific MAC address is always assigned the same IP address from DHCP?

   • AScope options
   • BReservation
   • CDynamic assignment
   • DExclusion
   • EStatic assignment

   Show answer

   Answer: B

   Explanation

   Perhaps you have noticed that DHCP dynamically assigns IP addresses and subnet masks to clients, but they need more IP addressing information than that in order to communicate properly on the network. For example, clients need DNS server addresses, they need a default gateway assigned, and they might even need the IP addresses associated with other key services, such as NTP and TFTP servers on the network. Your DHCP server can provide all this required IP addressing information. You enable this as part of the scope options you can configure on the DHCP server. The scope is the addresses that your DHCP server will lease out to clients. The scope options include the additional address information that must be distributed and can also include settings such as the lease time.

   Which of the following copper wire standards utilizes four pairs of wires to achieve Gigabit Ethernet speeds?

   • A1000BASE-FX
   • B1000BASE-T
   • C1000BASE.LR
   • D1000BASE-SX

   Show answer

   Answer: B

   Explanation

   1000BASE-T is a copper Ethernet standard that uses four pairs of twisted-pair cables to achieve Gigabit Ethernet speeds (1 Gbps). This standard is commonly used with Cat5e or higher-rated cabling. A. 1000BASE-FX: This standard uses fiber optics, not copper, to achieve Gigabit Ethernet speeds. C. 1000BASE-LR: This standard uses long-range fiber optics to achieve Gigabit Ethernet speeds over longer distances, not copper. D. 1000BASE-SX: This standard uses short-range fiber optics for Gigabit Ethernet speeds over shorter distances, not copper.

    • AIPSec
    • B802.1X
    • CEAP
    • DTACACS+

    Show answer

    Answer: B

It provides a framework for port-based network access control and is crucial for implementing NAC solutions. A. IPSec: IPSec is used for securing IP communications through encryption and authentication but is not specifically for network access control. C. EAP: Extensible Authentication Protocol (EAP) is an authentication framework used in conjunction with 802.1X but is not a standalone NAC component. D. TACACS+: TACACS+ (Terminal Access Controller Access-Control System Plus) is an authentication protocol used for network device management but is not specific to NAC for wired and wireless networks.
