NEW QUESTION # 11
Which Aruba technology will allow for device-specific passphrases to securely add headless devices to the WLAN?
- A. Temporal Key Integrity Protocol (TKIP)
- B. Opportunistic Wireless Encryption (OWE)
- C. Multiple Pre-Shared Key (MPSK)
- D. Wired Equivalent Privacy (WEP)
Answer: C
Explanation:
Explanation
Multiple Pre-Shared Key (MPSK) is a feature that allows device-specific or group-specific passphrases to securely add headless devices to the WLAN Wireless Local Area Network. WLAN is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building. . MPSK enhances the WPA2 PSK Wi-Fi Protected Access 2 Pre-Shared Key. WPA2 PSK is a method of securing your network using WPA2 with the use of the optional Pre-Shared Key (PSK) authentication, which was designed for home users without an enterprise authentication server. mode by allowing different PSKs for different devices on the same SSID Service Set Identifier. SSID is a case-sensitive, 32 alphanumeric character unique identifier attached to the header of packets sent over a wireless local-area network (WLAN). The SSID acts as a password when a mobile device tries to connect to the basic service set (BSS) - a component of the IEEE
802.11 WLAN architecture. . MPSK passwords can be generated or user-created and are managed by ClearPass Policy Manager12. References:

- D. ip route-static 10.2 10.0.255.255.255.0 172.16.1.1
Answer: A
Explanation:
The correct command to add a static route to a class-c-network 10.2.10.0 via a gateway of 172.16.1.1 is ip-route 10.2.10.0/24 172.16.1.1 . This command specifies the destination network address (10.2.10.0) and prefix length (/24) and the next-hop address (172.16.1 .1) for reaching that network from the switch. The other commands are either incorrect syntax or incorrect parameters for adding a static route. Reference: https://www.arubanetworks.com/techdocs/AOS-CX_10_04/NOSCG/Content/cx-noscg/ip-routing/static-routes.htm To add a static route in network devices, including Aruba switches, the correct command format generally includes the destination network, subnet mask (or CIDR notation for the mask), and the next-hop IP address. The command "ip route 10.2.10.0/24 172.16.1.1" correctly specifies the destination network "10.2.10.0" with a class C subnet mask indicated by "/24", and "172.16.1.1" as the next-hop IP address. This command is succinct and follows the standard syntax for adding a static route in many network operating systems, including ArubaOS-CX. The other options either have incorrect syntax or include additional unnecessary parameters that are not typically part of the standard command to add a static route.

NEW QUESTION # 16
An AP signal strength of .0000001 milliwatts equals how many dBm?
- A. -80 dBm
- B. -90 dBm
- C. -60 dBm
- D. -70 dBm
Answer: D
Explanation:
An AP signal strength of .0000001 milliwatts is equivalent to -80 dBm. The dBm scale is logarithmic, with every 10 dBm representing a tenfold increase or decrease in power. A signal strength of 1 milliwatt (mW) is 0 dBm, so a signal strength of .0000001 mW is 80 decibels less than 1 mW, which is -80 dBm.
NEW QUESTION # 17
Which authentication does Aruba's Captive Portal use?
- A. Layer 3 authentication
- B. Layer 2 authentication
- C. MAC authentication
- D. 802.1x authentication
Answer: A
Explanation:
Aruba's Captive Portal uses Layer 3 authentication, which means that it intercepts the client's HTTP requests and redirects them to a web page where the client can enter their credentials. The credentials are then verified by a RADIUS server or a local database before granting network access. Reference: https://www.arubanetworks.com/techdocs/Instant_86_WebHelp/Content/instant-ug/captive-portal/captive-portal-auth.htm Aruba's Captive Portal primarily uses Layer 3 authentication, which operates at the network layer. When a user connects to a network with a Captive Portal, they are redirected to a web page for authentication. This process involves the user entering credentials or accepting terms and conditions through a web interface before gaining full access to the network. The Captive Portal intercepts the user's web traffic at Layer 3, requiring them to authenticate before proceeding, which is why it's considered a form of Layer 3 authentication.

NEW QUESTION # 19
Based on the "snow ip route" output on an AruDaCX 8400. what type of route is "10.1 20 0/24, vrf default via
10.1.12.2. [1/0]"?
- A. local
- B. static
- C. connected
- D. OSPF
Answer: B
Explanation:
Explanation
A static route is a route that is manually configured on a router or switch and does not change unless it is modified by an administrator. Static routes are used to specify how traffic should reach specific destinations that are not directly connected to the device or that are not reachable by dynamic routing protocols. In Aruba CX switches, static routes can be configured using the ip route command in global configuration mode. Based on the "show ip route" output on an Aruba CX 8400 switch, the route "10.1 20 0/24, vrf default via 10.1.12.2,
[1/0]" is a static route because it has an administrative distance of 1 and a metric of 0, which are typical values for static routes. References: https://en.wikipedia.org/wiki/Static_routing

NEW QUESTION # 24
What does WPA3-Personal use as the source to generate a different Pairwise Master Key (PMK) each time a station connects to the wireless network?
- A. Key Encryption Key (KEK)
- B. Simultaneous Authentication of Equals (SAE)
- C. Session-specific information (MACs and nonces)
- D. Opportunistic Wireless Encryption (OWE)
Answer: C
Explanation:
Explanation
The source that WPA3-Personal uses to generate a different Pairwise Master Key (PMK) each time a station connects to the wireless network is session-specific information (MACs and nonces). WPA3-Personal uses Simultaneous Authentication of Equals (SAE) to replace PSK authentication in WPA2-Personal. SAE is a secure key establishment protocol that uses a Diffie-Hellman key exchange to derive a shared secret between two parties without revealing it to an eavesdropper. SAE involves the following steps:
The station and the access point exchange Commit messages that contain their MAC addresses and random numbers called nonces.
The station and the access point use their own passwords and the received MAC addresses and nonces to calculate a shared secret called SAE Password Element (PE).
The station and the access point use their own PE and the received MAC addresses and nonces to calculate a shared secret called SAE Key Seed (KS).
The station and the access point use their own KS and the received MAC addresses and nonces to calculate a shared secret called SAE Key Confirmation Key (KCK).
The station and the access point use their own KCK and the received MAC addresses and nonces to calculate a confirmation value called SAE Confirm.
The station and the access point exchange Confirm messages that contain their SAE Confirm values.
The station and the access point verify that the received SAE Confirm values match their own calculated values. If they match, the authentication is successful and the station and the access point have established a shared secret called SAE PMK.
The SAE PMK is different for each session because it depends on the MAC addresses and nonces that are exchanged in each authentication process. The SAE PMK is used as an input for the 4-way handshake that generates the Pairwise Temporal Key (PTK) for encrypting data frames.
The other options are not sources that WPA3-Personal uses to generate a different PMK each time a station connects to the wireless network because:
Opportunistic Wireless Encryption (OWE): OWE is a feature that provides encryption for open networks without requiring authentication or passwords. OWE uses a similar key establishment protocol as SAE, but it does not generate a PMK. Instead, it generates a Pairwise Secret (PS) that is used as an input for the 4-way handshake that generates the PTK.
Simultaneous Authentication of Equals (SAE): SAE is not a source, but a protocol that uses session-specific information as a source to generate a different PMK each time a station connects to the wireless network.
Key Encryption Key (KEK): KEK is not a source, but an output of the 4-way handshake that generates the PTK. KEK is used to encrypt group keys that are distributed by the access point.

NEW QUESTION # 26
What are the main characteristics of the 6 GHz band?
- A. The 6 GHz band is fully backward compatible with the existing bands.
- B. Low Power Devices are allowed for indoor and outdoor usage.
- C. Less RF signal is absorb by objects in a 6 GHz WLAN.
- D. In North America, the 6 GHz band offers more 80 MHz channels than there are 40 MHz channels in the
5 GHz band.
Answer: D
Explanation:
Explanation
The main characteristic of the 6 GHz band that is true among the given options is that in North America, the 6 GHz band offers more 80 MHz channels than there are 40 MHz channels in the 5 GHz band. This characteristic provides more spectrum availability, less interference, and higher throughput for wireless devices that support Wi-Fi 6E Wi-Fi Enhanced (Wi-Fi 6E) is an extension of Wi-Fi 6 (802.11ax) standard that operates in the newly available unlicensed frequency spectrum around 6 GHz in addition to existing bands below it. Some facts about this characteristic are:
In North America, there are up to seven non-overlapping channels available in each of three channel widths (20 MHz, 40 MHz, and 80 MHz) in the entire unlicensed portion of the new spectrum (5925-7125 MHz). This means there are up to 21 non-overlapping channels available for Wi-Fi devices in total.
In comparison, in North America, there are only nine non-overlapping channels available in each of two channel widths (20 MHz and 40 MHz) in the entire unlicensed portion of the existing spectrum below it (2400-2483 MHz and 5150-5825 MHz). This means there are only up to nine non-overlapping channels available for Wi-Fi devices in total.
Therefore, in North America, there are more than twice as many non-overlapping channels available in each channel width in the new spectrum than in the existing spectrum below it.
Specifically, there are more than twice as many non-overlapping channels available at 80 MHz width (seven) than at 40 MHz width (three) in the existing spectrum below it.
The other options are not true because:
Less RF signal is absorbed by objects in a 6 GHz WLAN: This option is false because higher frequency signals tend to be more absorbed by objects than lower frequency signals due to 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 . Therefore, RF signals in a 6 GHz WLAN would be more absorbed by objects than RF signals in a lower frequency WLAN.
The 6 GHz band is fully backward compatible with existing bands: This option is false because Wi-Fi devices need to support Wi-Fi 6E standard to operate in the new spectrum around 6 GHz . Existing Wi-Fi devices that do not support Wi-Fi 6Estandard cannot use this spectrum and can only operate in existing bands below it.
Low Power Devices are allowed for indoor and outdoor usage: This option is false because Low Power Indoor Devices (LPI) are only allowed for indoor usage under certain power limits and registration requirements . Outdoor usage of LPI devices is prohibited by regulatory authorities such as FCC Federal Communications Commission (FCC) is an independent agency of United States government that regulates communications by radio, television, wire, satellite, and cable across United States . However, outdoor usage of Very Low Power Devices (VLP) may be allowed under certain power limits and without registration requirements.

NEW QUESTION # 30
A network technician at a branch office is connecting VolP phones to a newly configured AOS-CX switch. Users are complaining that voice quality is not as good as at the corporate office. Further investigation shows the local-priority value at the branch office is 1 while at the corporate office is 5.
What describes the issue regarding the default QoS behavior on the AOS-CX switch?
- A. The QoS trust is set to DSCP by default, and the VolP phone's local-priority value is mapped to 1.
- B. The QoS trust is set to CoS by default, and the VolP phone's local-priority value is mapped to 1.
- C. The QoS trust is set to none by default, and each VolP phone's local priority is configured for CoS map entry 0.
- D. The QoS trust is set to none by default, and each VolP phone's local priority is configured for CoS map entry 1.
Answer: D
Explanation:
In an AOS-CX switch, if the QoS trust mode is not configured, it is set to none by default. The VoIP phones will mark their traffic with a local-priority value, which, if the QoS trust mode is none, will correspond to CoS map entry 1 by default. The local-priority value of 1 at the branch office likely indicates that the traffic is not being prioritized correctly compared to the corporate office, where a local-priority of 5 suggests a higher level of prioritization for voice traffic.
