質問 # 138
A bank installed a new smart TV to stream online video services, but the smart TV was not able to connect to the branch Wi-Fi. The next day. a technician was able to connect the TV to the Wi-Fi, but a bank laptop lost network access at the same time. Which of the following is the MOST likely cause?
- A. DHCP scope exhaustion
- B. AP configuration reset
- C. Hidden SSID
- D. Channel overlap
正解：A
解説：
DHCP scope exhaustion is the situation when a DHCP server runs out of available IP addresses to assign to clients. DHCP stands for Dynamic Host Configuration Protocol, which is a network protocol that automatically assigns IP addresses and other configuration parameters to clients on a network. A DHCP scope is a range of IP addresses that a DHCP server can distribute to clients. If the DHCP scope is exhausted, new clients will not be able to obtain an IP address and connect to the network. This can explain why the smart TV was not able to connect to the branch Wi-Fi on the first day, and why the bank laptop lost network access on the next day when the TV was connected. The technician should either increase the size of the DHCP scope or reduce the lease time of the IP addresses to avoid DHCP scope exhaustion.

During an incident, an analyst sends reports regularly to the investigation and leadership teams. Which of the following best describes how Pll should be safeguarded during an incident?
- A. Implement data encryption and store the data so only the company has access.
- B. Implement data encryption and create a standardized procedure for deleting data that is no longer needed.
- C. Ensure permissions are limited to the investigation team and encrypt the data.
- D. Ensure the permissions are open only to the company.
正解：B
解説：
PII stands for Personally Identifiable Information, which is any data that can be used to identify, contact, or locate a specific individual, such as name, address, phone number, email, social security number, and so on. PII should be safeguarded during an incident to protect the privacy and security of the individuals involved, and to comply with the legal and ethical obligations of the organization. One way to safeguard PII during an incident is to implement data encryption, which is a process of transforming data into an unreadable format that can only be accessed by authorized parties who have the decryption key. Data encryption can prevent unauthorized access, modification, or disclosure of PII by malicious actors or third parties. Another way to safeguard PII during an incident is to create a standardized procedure for deleting data that is no longer needed, such as after the incident is resolved or the investigation is completed. Deleting data that is no longer needed can reduce the risk of data breaches, data leaks, or data theft, and can also save storage space and resources. A standardized procedure for deleting data can ensure that the data is erased securely and completely, and that the deletion process is documented and audited.

A network technician is attempting to increase throughput by configuring link port aggregation between a Gigabit Ethernet distribution switch and a Fast Ethernet access switch. Which of the following is the BEST choice concerning speed and duplex for all interfaces that are participating in the link aggregation?
- A. Full duplex and 100MB speed
- B. Half duplex and 1GB speed
- C. Full duplex and 1GB speed
- D. Half duplex and 10OMB speed
正解：C
解説：
Explanation
The best choice for configuring link port aggregation between a Gigabit Ethernet distribution switch and a Fast Ethernet access switch is to use full duplex and 1GB speed for all interfaces that are participating in the link aggregation. This will allow for maximum throughput, as the full duplex connection will enable simultaneous sending and receiving of data, and the 1GB speed will ensure that the data is transferred quickly.
According to the CompTIA Network+ Study Guide, "Full-duplex Ethernet allows the network adapter to transmit and receive data simultaneously, which can result in double the bandwidth of half-duplex Ethernet." Additionally, the official text states, "Ethernet and Fast Ethernet use different speeds for data transmission, with Ethernet being 1,000 megabits (1 gigabit) per second and Fast Ethernet being 100 megabits per second."

Which of the following protocols uses Dijkstra's algorithm to calculate the LOWEST cost between routers?
- A. RIP
- B. EIGRP
- C. BGP
- D. OSPF
正解：D
解説：
Explanation
OSPF stands for Open Shortest Path First and is a link-state routing protocol that uses Dijkstra's algorithm to calculate the lowest cost between routers. OSPF assigns a cost value to each link based on factors such as bandwidth, delay, or reliability, and builds a map of the network topology. OSPF then uses Dijkstra's algorithm to find the shortest path from each router to every other router in the network1. RIP stands for Routing Information Protocol and is a distance-vector routing protocol that uses hop count as the metric to find the best path. BGP stands for Border Gateway Protocol and is a path-vector routing protocol that uses attributes such as AS path, local preference, or origin to select the best route. EIGRP stands for Enhanced Interior Gateway Routing Protocol and is a hybrid routing protocol that uses a composite metric based on bandwidth, delay, load, and reliability.

A wireless network technician is receiving reports from some users who are unable to see both of the corporate SSIDs on their mobile devices. A site survey was recently commissioned, and the results verified acceptable RSSI from both APs in all user areas. The APs support modern wireless standards and are all broadcasting their SSIDs. The following table shows some of the current AP settings:
Which of the following changes would result in all of the user devices being capable of seeing both corporate SSIDs?
- A. Configuring the highest power settings for both APs
- B. Configuring both APs to use the 802.11ac wireless standard
- C. Implementing omnidirectional antennas for both APs
- D. Implementing the WPA2 Enterprise authentication standard
正解：B
解説：
Explanation
The change that would result in all of the user devices being capable of seeing both corporate SSIDs is configuring both APs to use the 802.11ac wireless standard. 802.11ac is a wireless standard that operates in the 5 GHz frequency band and offers high data rates and performance. However, not all wireless devices support 802.11ac, especially older ones that only operate in the 2.4 GHz frequency band. In the table, AP1 uses 802.11b, which is an outdated wireless standard that operates in the 2.4 GHz frequency band and offers low data rates and performance. AP2 uses 802.11a, which is an older wireless standard that operates in the 5 GHz frequency band and offers moderate data rates and performance. Therefore, some user devices may not be able to see both SSIDs because they are incompatible with either 802.11b or 802.11a. By configuring both APs to use 802.11ac, which is backward compatible with previous wireless standards, all user devices should be able to see both SSIDs.
