質問 # 12
What does a wireless client do first when its countdown timer reaches zero and it receives a Transmit Opportunity (TXOP)?
- A. It sends a CTS-to-self announcement to the ESP gateway.
- B. It sends a CTS-to-self announcement to the AP and all other clients.
- C. It sends a reassociation request frame to the AP and sends its Data Frames.
- D. It immediately sends its Data Frames and receives an ACK from the AP.
正解：D
解説：
When a wireless client's countdown timer (also known as a backoff timer) reaches zero during contention-based access periods, and it receives a Transmit Opportunity (TXOP), it has the right to transmit its data frames on the medium. After sending the data frames, it expects an acknowledgment (ACK) from the Access Point (AP) to ensure the frames were received successfully.
質問 # 13
Which statement is correct when comparing 5 GHz and 6 GHz channels with identical channel widths?
- A. 5 GHz channels travel different distances and provide the same throughputs to clients compared to 6 GHz channels
- B. 5 GHz channels travel the same distances and provide different throughputs to clients compared to 6 GHz channels
- C. 5 GHz channels travel the same distances and provide the same throughputs to clients compared to 6 GHz channels
- D. 5 GHz channels travel different distances and provide different throughputs to clients compared to 6 GHz channels
正解：D
解説：
Explanation
The correct statement when comparing 5 GHz and 6 GHz channels with identical channel widths is that 5 GHz channels travel different distances and provide different throughputs to clients compared to 6 GHz channels.
This statement reflects the fact that higher frequency signals tend to have higher attenuation Attenuation is a general term that refers to any reduction in signal strength during transmission over distance or through an object or medium . Higher attenuation means that higher frequency signals have shorter range and lower throughput than lower frequency signals. Some facts about this statement are:
5 GHz channels have lower frequency than 6 GHz channels, which means they have lower attenuation than 6 GHz channels.
Lower attenuation means that 5 GHz channels can travel longer distances and provide higher throughputs to clients than 6 GHz channels with identical channel widths.
However, the difference in distance and throughput between 5 GHz and 6 GHz channels may not be significant in indoor environments where there are many obstacles and reflections that affect signal propagation.
The advantage of using 6 GHz channels over 5 GHz channels is that they offer more spectrum availability, less interference, and more non-overlapping channels than 5 GHz channels.
The other options are not correct because:
5 GHz channels travel the same distances and provide different throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not travel the same distances as 6 GHz channels due to higher attenuation of higher frequency signals.
5 GHz channels travel the same distances and provide the same throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not travel the same distances or provide the same throughputs as 6 GHz channels due to higher attenuation of higher frequency signals.
5 GHz channels travel different distances and provide the same throughputs to clients compared to 6 GHz channels: This option is false because 5 GHz channels do not provide the same throughputs as
6 GHz channels due to higher attenuation of higher frequency signals.

What can be done to dynamically set the PoE Priority on a switch port when deploying IP cameras APs. and other PoE devices?
- A. Enable Quick PoE on the switch modules
- B. Configure PoE power management to Class-based Mode
- C. Configure PoE power management to Dynamic Mode
- D. Enable profiling for device provisioning
正解：D
解説：
Profiling is a feature that allows Aruba switches to automatically identify and classify devices connected to them based on various attributes such as MAC address, DHCP options, LLDP information, etc. Profiling can be used to dynamically set the PoE priority on a switch port based on the device type and power requirements. For example, an IP camera may have a higher PoE priority than a printer or a PC. Profiling can also be used to apply other configuration settings such as VLANs, ACLs, QoS, etc. based on the device profile.

質問 # 16
You need to configure wireless access for several classes of loT devices, some of which operate only with 802 11b. Each class must have a unique PSK and will require a different security policy applied as a role There will be 15-20 different classes of devices and performance should be optimized Which option fulfills these requirements''
- A. Individual SSIDs with unique PSK for each loT class, using 5GHz and 6 GHz bands
- B. Individual SSIDs with unique PSK for each loT class, using 2.4GHZ and 5GHz band
- C. Single SSID with MPSK for each loT class using 2.4GHz and 5 GHz bands
- D. Single SSID with MPSK for each loT class using 5 GHz and 6 GHz bands
正解：C
解説：
For configuring wireless access for multiple classes of IoT devices with varying security requirements, using a single SSID with Multiple Pre-Shared Keys (MPSK) is an efficient solution. MPSK allows different devices or groups of devices to connect to the same SSID but with unique PSKs, facilitating unique security policies for each class. Given that some IoT devices only support 802.11b, which operates in the 2.4GHz band, it is essential to include the 2.4GHz band in the configuration. The 5GHz band should also be included to support devices capable of operating in that band and to optimize network performance. The 6GHz band (option A) is not suitable since 802.11b devices are not compatible with it. Individual SSIDs for each IoT class (options C and D) would unnecessarily complicate network management and SSID overhead.
質問 # 17
A hacker has altered a user's 3-Way Handshake in order to gain access to their session.
Which security mechanism would intelligently deny this traffic?
- A. Stateless firewall
- B. Stateful firewall
- C. Out-of-band management (00BM)
- D. Access Control List (ACL)
正解：B
解説：
A stateful firewall would intelligently deny traffic from a hacker attempting to alter a user's 3-Way Handshake to gain access to their session. Stateful firewalls keep track of the state of active connections and can recognize if an incoming packet is part of an established session. This allows them to detect and block unauthorized access attempts that do not match the known state of a connection.

What are two characteristics of ClientMatch? (Select two.)
- A. An algorithm to adjust RF patterns.
- B. It optimizes channels of an AP.
- C. It is an Aruba patented technology.
- D. It helps to move sticky clients to another AP.
- E. It is used to locate a client.
正解：C、D
解説：
ClientMatch is an Aruba patented technology that helps to move sticky clients-clients that stay connected to an AP even when there are better APs available-to a more appropriate AP. This technology ensures that clients are always connected to the best available AP, optimizing both the client's performance and the overall performance of the wireless network.
質問 # 20
Which commands are used to set a default route to 10.4.5.1 on an Aruba CX switch when ln-band management using an SVl is being used?
- A. ip route 0.0 0 0/0 10.4.5.1
- B. ip route 0 0 0.070 10.4 5.1 vrf mgmt
- C. default-gateway 10.4.5.1
- D. iP default-gateway 10.4.5.1
正解：A
解説：
The command that is used to set a default route to 10.4.5.1 on an Aruba CX switch when in-band management using an SVI is being used is ip route 0.0 0 0/0 10.4.5.1 . This command specifies the destination network address (0.0 0 0) and prefix length (/0) and the next-hop address (10.4.5.1) for reaching any network that is not directly connected to the switch. The default route applies to the default VRF Virtual Routing and Forwarding. VRF is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. VRFs are typically used to segment network traffic for security, privacy, or administrative purposes. , which is used for in-band management traffic that goes through an SVI Switch Virtual Interface. SVI is a virtual interface on a switch that allows the switch to route packets between different VLANs on the same switch or different switches that are connected by a trunk link. An SVI is associated with a VLAN and has an IP address and subnet mask assigned to it12.

質問 # 21
What is indicated by a solid amber radio status LED on an Aruba AP?
- A. Not enough PoE is provided from the switch to power both radios of the AP
- B. The radio is working the 5 GHz band only.
- C. The radio is working in mesh mode
- D. The radio is enabled in monitor or spectrum analysis mode
正解：A
解説：
On an Aruba AP, a solid amber radio status LED indicates: A. Not enough PoE is provided from the switch to power both radios of the AP When the radio status LED on an Aruba AP shows a solid amber color, it typically signifies that the PoE (Power over Ethernet) supplied by the switch is insufficient to power both radios of the AP (usually the
2.4 GHz and 5 GHz bands). This may require checking the PoE budget of the switch or using a higher- powered PoE source.
Other options, such as the radio working in mesh mode, operating only in the 5 GHz band, or being enabled in monitor or spectrum analysis mode, typically do not result in the LED showing a solid amber color.

質問 # 25
Which part of the WPA Key Hierarchy is used to encrypt and/or decrypt data''
- A. Pairwise Temporal Key (PTK)
- B. number used once (nonce)
- C. Key Confirmation Key (KCK)
- D. Pairwise Master Key (PMK)
正解：A
解説：
Explanation
The part of WPA Key Hierarchy that is used to encrypt and/or decrypt data is Pairwise Temporal Key (PTK).
PTK is a key that is derived from PMK Pairwise Master Key (PMK) is a key that is derived from PSK Pre-shared Key (PSK) is a key that is shared between two parties before communication begins , ANonce Authenticator Nonce (ANonce) is a random number generated by an authenticator (a device that controls access to network resources, such as an AP) , SNonce Supplicant Nonce (SNonce) is a randomnumber generated by supplicant (a device that wants to access network resources, such as an STA) , AA Authenticator Address (AA) is MAC address of authenticator , SA Supplicant Address (SA) is MAC address of supplicant using Pseudo-Random Function (PRF). PTK consists of four subkeys:
KCK Key Confirmation Key (KCK) is used for message integrity check
KEK Key Encryption Key (KEK) is used for encryption key distribution
TK Temporal Key (TK) is used for data encryption
MIC Message Integrity Code (MIC) key
The subkey that is specifically used for data encryption is TK Temporal Key (TK). TK is also known as Pairwise Transient Key (PTK). TK changes periodically during communication based on time or number of packets transmitted.
The other options are not part of WPA Key Hierarchy because:
PMK: PMK is not part of WPA Key Hierarchy, but rather an input for deriving PTK.
KCK: KCK is part of WPA Key Hierarchy, but it is not used for data encryption, but rather for message integrity check.
Nonce: Nonce is not part of WPA Key Hierarchy, but rather an input for deriving PTK.

You need to configure wireless access for several classes of loT devices, some of which operate only with 802
11b. Each class must have a unique PSK and will require a different security policy applied as a role There will be 15-20 different classes of devices and performance should be optimized Which option fulfills these requirements''
- A. Individual SSIDs with unique PSK for each loT class, using 5GHz and 6 GHz bands
- B. Single SSID with MPSK for each loT class using 2.4GHz and 5 GHz bands
- C. Single SSID with MPSK for each loT class using 5 GHz and 6 GHz bands
- D. Individual SSIDs with unique PSK for each loT class, using 2.4GHZ and 5GHz band
正解：D
解説：
Explanation
The option that fulfills the requirements is to create individual SSIDs with unique PSK for each loT class, using 2.4 GHz and 5 GHz band. This option provides the following benefits:
Each loT class has a unique PSK that can be used to apply a different security policy as a role. This enhances the security and flexibility of the WLAN network.
Individual SSIDs allow for better isolation and management of different loT classes. This improves the performance and scalability of the WLAN network.
Using both 2.4 GHz and 5 GHz bands allows for backward compatibility with loT devices that operate only with 802.11b, which uses the 2.4 GHz band . It also allows for higher throughput and less interference for loT devices that support 802.11a, 802.11g, 802.11n, or 802.11ac, which use the 5 GHz band2.
The other options do not fulfill the requirements because:
Single SSID with MPSK for each loT class using 5 GHz and 6 GHz bands: This option does not support loT devices that operate only with 802.11b, which uses the 2.4 GHz band . It also does not optimize the performance of the WLAN network, as a single SSID may cause co-channel interference and congestion among different loT classes.
Single SSID with MPSK for each loT class using 2.4 GHz and 5 GHz bands: This option does not optimize the performance of the WLAN network, as a single SSID may cause co-channel interference and congestion among different loT classes.
Individual SSIDs with unique PSK for each loT class, using 5 GHz and 6 GHz bands: This option does not support loT devices that operate only with 802.11b, which uses the 2.4 GHz band1.
