Question #31
A technician was cleaning a storage closet and found a box of transceivers labeled 8Gbps.
Which of the following protocols uses those transceivers?
- A . Coaxial over Ethernet
- B . Internet Small Computer Systems Interface
- C . Fibre Channel
- D . Gigabit interface converter
Correct Answer: C
C
Explanation:
Fibre Channel is a high-speed network technology that is mainly used for storage area networks (SANs). It provides reliable and secure data transfer between servers and storage devices, such as disk arrays, tape libraries, and optical jukeboxes. It uses protocols such as SCSI, FCP, and FICON to transport data over optical fiber or copper cables678
Fibre Channel transceivers are devices that convert electrical signals to optical signals and vice versa, and allow Fibre Channel devices to communicate over different media types and distances. They are usually pluggable modules that fit into standard ports on Fibre Channel switches, adapters, and storage devices. They have different specifications and standards, such as SFP, SFP+, QSFP, and CFP, depending on the data rate, wavelength, and cable type they support.
8 Gbps transceivers are Fibre Channel transceivers that support a data rate of 8 gigabits per second, which is also known as Fibre Channel-8G or 8GFC. They are typically SFP+ modules that use 850 nm wavelength and multimode fiber for short-reach applications, or 1310 nm wavelength and single-mode fiber for long-reach applications. They can support cable distances up to 10 km or 40 km, depending on the fiber type and quality.

Which of the following should a network technician do FIRST?
- A . Check the system’s IP address
- B . Do a ping test against the servers
- C . Reseat the cables into the back of the PC
- D . Ask what changes were made
Correct Answer: D
D
Explanation:
When a user reports being unable to access network resources after making some changes, the network technician should first ask the user what changes were made. This information can help the technician identify the cause of the issue and determine the appropriate course of action.

Question #33
Several users with older devices are reporting intermittent connectivity while in an outdoor patio are a. After some research, the network administrator determines that an outdoor WAP might help with the issue. However, the company does not want the signal to bleed into the building and cause interference.
Which of the following should the network administrator perform to BEST resolve the issue?
- A . Disable the SSID broadcast on the WAP in the patio area.
- B . Install a WAP and enable 5GHz only within the patio area.
- C . Install a directional WAP in the direction of the patio.
- D . Install a repeater on the back wall of the patio area.
Correct Answer: C
C
Explanation:
A directional WAP is a wireless access point that emits a focused signal in a specific direction, rather than a circular or omnidirectional pattern12.
A directional WAP can help to improve the wireless coverage and performance in a targeted area, such as an outdoor patio, while minimizing the signal leakage and interference in other areas, such as the building interior12.
A directional WAP can also reduce the exposure to external interference and noise from other sources, such as neighboring networks or devices12.
Disabling the SSID broadcast on the WAP in the patio area would not prevent the signal from bleeding into the building, nor would it improve the connectivity for the users. It would only make the network name invisible to casual scanners, but not to determined attackers3.
Installing a WAP and enabling 5GHz only within the patio area would not prevent the signal from bleeding into the building, nor would it improve the connectivity for the users with older devices. The 5GHz band has a shorter range and a higher attenuation rate than the 2.4GHz band, which means it is more susceptible to obstacles and interference. Moreover, some older devices may not support the 5GHz band at all4.
Installing a repeater on the back wall of the patio area would not prevent the signal from bleeding into the building, nor would it improve the connectivity for the users. A repeater is a device that amplifies and retransmits a wireless signal, but it also introduces latency and reduces bandwidth. A repeater does not change the direction or shape of the signal, so it would not help to isolate the patio area from the building5.

Question #34
An engineer is troubleshooting poor performance on the network that occurs during work hours.
Which of the following should the engineer do to improve performance?
- A . Replace the patch cables.
- B . Create link aggregation.
- C . Create separation rules on the firewall.
- D . Create subinterfaces on the existing port.
Correct Answer: B
B
Explanation:
Link aggregation is a technique that allows multiple network interfaces to act as a single logical interface, increasing the bandwidth and redundancy of the network connection. Link aggregation can improve the performance of the network by balancing the traffic load across multiple links and providing failover in case one link fails. Link aggregation is also known as port trunking, port channeling, or NIC teaming.

Question #35
A technician is expanding a wireless network and adding new access points. The company requires that each access point broadcast the same SSID.
Which of the following should the technician implement for this requirement?
- A . MIMO
- B . Roaming
- C . Channel bonding
- D . Extended service set
Correct Answer: D
D
Explanation:
An extended service set (ESS) is a wireless network that consists of two or more access points (APs) that share the same SSID and are connected by a distribution system, such as a switch or a router. An ESS allows wireless clients to roam seamlessly between different APs without losing connectivity or changing network settings. An ESS can also increase the coverage area and capacity of a wireless network

Question #36
Which of the following provides redundancy on a file server to ensure the server is still connected to a LAN even in the event of a port failure on a switch?
- A . NIC teaming
- B . Load balancer
- C . RAID array
- D . PDUs
Correct Answer: A
A
Explanation:
NIC teaming, also known as network interface card teaming or link aggregation, allows multiple network interface cards to be grouped together to provide redundancy and increased throughput. In the event of a port failure on a switch, NIC teaming ensures that the file server remains connected to the LAN by automatically switching to another network interface card.

Question #37
A company wants to mitigate unauthorized physical connectivity after implementing a hybrid work schedule.
Which of the following will the company most likely configure?
- A . Intrusion prevention system
- B . DHCP snooping
- C . ARP inspection
- D . Port security
Correct Answer: D
D
Explanation:
Port security is a feature that allows network administrators to limit the number of devices that can connect to a switch port, based on the MAC address of the device. This can prevent unauthorized physical connectivity by blocking any device that is not on the allowed list or exceeding the maximum number of devices per port. Port security can also trigger an action, such as shutting down the port or sending an alert, when a violation occurs.

Question #39
Which of the following OSI model layers will ensure messages are transmitted to their destinations and no data is duplicated?
- A . Session
- B . Data link
- C . Network
- D . Transport
Correct Answer: D
D
Explanation:
The transport layer is the fourth layer of the OSI model, and it is responsible for end-to-end delivery of data over a network. It uses standard protocols such as TCP, UDP, and DCCP to enhance its functionalities. One of the main functions of the transport layer is to ensure that messages are transmitted to their destinations reliably and in the correct order. It also prevents data duplication by using sequence numbers, acknowledgments, and retransmission mechanisms

Which Of the following should be prepared?
- A . Cloud site
- B . Warm site
- C . Hot site
- D . Cold site
Correct Answer: C
C
Explanation:
A hot site is a backup site that is fully equipped and ready to take over the operations of the primary site in the event of a disaster.
