NEW QUESTION # 87
A technician reviews a network performance report and finds a high level of collisions happening on the network. At which of the following layers of the OSI model would these collisions be found?
- A. Layer 1
- B. Layer 3
- C. Layer 4
- D. Layer 7
Answer: A
Explanation:
Collisions occur when two or more devices try to transmit signals on the same physical medium at the same time. This causes interference and data loss. Collisions can only happen at the physical layer of the OSI model, which is responsible for transmitting and receiving raw bits over a physical medium such as a cable or a wireless channel. The physical layer does not have any mechanism to prevent or resolve collisions. Therefore, higher layers of the OSI model, such as the data link layer, need to implement protocols to detect and recover from collisions, such as CSMA/CD for Ethernet networks.

NEW QUESTION # 89
A network security technician is designing a solution for a secure remote access scheme with the following requirements:
* The solution must allow for users at multiple locations to access corporate resources.
* The on-premises equipment will not handle non-corporate, resource-bound traffic.
Which of the following should the network security technician consider when designing the solution? (Select two).
- A. Client-to-site VPN
- B. Personal VPN
- C. Site-to-site VPN
- D. Split-tunnel VPN
- E. Full-tunnel VPN
- F. Clientless VPN
Answer: A,D
Explanation:
Explanation
A client-to-site VPN and a split-tunnel VPN are the best options for designing a secure remote access scheme that meets the given requirements. A client-to-site VPN allows users at multiple locations to access corporate resources over the internet by creating a secure tunnel between their devices and a VPN concentrator on the corporate network1. A split-tunnel VPN allows the on-premises equipment to handle only the traffic that is destined for the corporate resources, while the non-corporate traffic is routed directly to the internet without passing through the VPN tunnel2. This reduces the bandwidth and processing load on the corporate network and improves the performance of the remote access.

- A. LACP
- B. Jumbo frames
- C. Half duplex
- D. 802.1Q
Answer: B
Explanation:
Jumbo frames are Ethernet frames that can carry more than 1500 bytes of payload data. Jumbo frames can reduce the overhead and improve the throughput of large file transfers, as fewer frames are needed to send the same amount of data. Jumbo frames can be used to provide faster transfer times, as long as the network devices support them
NEW QUESTION # 91
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 both APs to use the 802.11ac wireless standard
- B. Implementing the WPA2 Enterprise authentication standard
- C. Implementing omnidirectional antennas for both APs
- D. Configuring the highest power settings for both APs
Answer: A
Explanation:
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.

NEW QUESTION # 92
A network technician is observing the behavior of an unmanaged switch when a new device is added to the network and transmits data. Which of the following BEST describes how the switch processes this information?
- A. The data is flooded out of every port but only in the VLAN where it is located.
- B. The data is flooded out of every port, excluding the VLAN where it is located
- C. The data is flooded out of every port, except the one on which it came in
- D. The data is flooded out of every port. including the one on which it came in.
Answer: C
Explanation:
Explanation
The switch processes the data by flooding it out of every port, except the one on which it came in. Flooding is a process where a switch sends a data frame to all ports except the source port when it does not have an entry for the destination MAC address in its MAC address table. Flooding allows the switch to learn the MAC addresses of the devices connected to its ports and update its MAC address table accordingly. Flooding also ensures that the data frame reaches its intended destination, even if the switch does not know its location.

NEW QUESTION # 97
A network administrator is troubleshooting a connection to a remote site. The administrator runs a command and sees the following output:
Which of the following is the cause of the connection issue?
- A. Switching loop
- B. Routing loop
- C. Broadcast storm
- D. Asymmetrical routing
Answer: B
Explanation:
Explanation
The cause of the connection issue is a routing loop. A routing loop is a situation where a packet is forwarded in circles between routers, never reaching its destination. A routing loop can be caused by misconfigured or inconsistent routing tables, or by routing protocols that do not update their information properly. A routing loop can be detected by using the traceroute command, which shows the path taken by a packet from the source to the destination. The traceroute output in the image shows that the packet is bouncing back and forth between two routers, 10.12.2.1 and 10.12.2.2, indicating a routing loop.

The network administrator can see the devices connected to the APs at all times. Which of the following steps will MOST likely determine the cause of the issue?
- A. Verify the session time-out configuration on the captive portal settings
- B. Check for encryption protocol mismatch on the client's wireless settings
- C. Confirm that a valid passphrase is being used during the web authentication
- D. Investigate for a client's disassociation caused by an evil twin AP
Answer: A
Explanation:
A captive portal is a web page that requires users to authenticate before they can access the internet. If the session time-out configuration is too short, users may experience intermittent internet connectivity and have to reconnect using the web authentication process each time. The network administrator can verify the session time-out configuration on the captive portal settings and adjust it if needed.

NEW QUESTION # 99
A network administrator is concerned about a rainbow table being used to help access network resources.
Which of the following must be addressed to reduce the likelihood of a rainbow table being effective?
- A. Remote access policy
- B. Password policy
- C. Data loss prevention policy
- D. Acceptable use policy
Answer: B
Explanation:
Explanation
A password policy must be addressed to reduce the likelihood of a rainbow table being effective. A rainbow table is a precomputed table of hashed passwords and their corresponding plaintext values. A rainbow table can be used to crack hashed passwords by performing a reverse lookup of the hash value in the table. A password policy is a set of rules and guidelines that define how passwords should be created, used, and managed in an organization. A password policy can help prevent rainbow table attacks by enforcing strong password requirements, such as length, complexity, expiration, and history. A strong password is one that is hard to guess or crack by using common methods such as brute force or dictionary attacks. References:
