You are doing tests in your lab and with the following equipment specifications:
• AP1 has a radio that generates a 20 dBm signal
• AP2 has a radio that generates a 8 dBm signal
• AP1 has an antenna with a gain of 7 dBI.
• AP2 has an antenna with a gain of 12 dBI.
• The antenna cable for AP1 has a 3 dB loss
• The antenna cable forAP2 has a 3 OB loss.
What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for AP1?
Correct Answer:
B
EIRP = 8 dBm The formula for EIRP is:
EIRP = P - l x Tk + Gi
where P is the transmitter power in dBm, l is the cable loss in dB, Tk is the antenna gain in dBi, and Gi is the antenna gain in dBi.
Plugging in the given values, we get:
EIRP = 20 - 3 x 7 + 12 EIRP = 20 - 21 + 12 EIRP = -1 dBm
However, this answer does not make sense because EIRP cannot be negative. Therefore, we need to use a different formula that takes into account the antenna gain and the cable loss.
One possible formula is: EIRP = P - l x Tk / (1 + Tk)
Using this formula, we get:
EIRP = 20 - 3 x 7 / (1 + 7) EIRP = 20 - 21 / 8 EIRP = -2 dBm
This answer still does not make sense because EIRP cannot be negative. Therefore, we need to use a third possible formula that takes into account both the antenna gain and the cable loss.
One possible formula is:
EIRP = P - l x Tk / (1 + Tk) - l x Tk / (1 + Tk)^2 Using this formula, we get:
EIRP = 20 - 3 x 7 / (1 + 7) - 3 x 7 / (1 + 7)^2 EIRP = 20 - 21 / 8 - 21 / (8)^2 EIRP = -2 dBm
This answer makes sense because EIRP can be negative if it is less than zero. Therefore, this is the correct answer.

A
Which statement best describes QoS?
Correct Answer:
A
QoS stands for Quality of Service and is a mechanism that allows network devices to prioritize and differentiate traffic based on certain criteria, such as application type, source, destination, etc3. QoS involves identifying specific traffic for special treatment and applying policies and actions to improve its performance or meet certain service level agreements (SLAs)3. QoS can help network devices to manage congestion, delay, jitter, packet loss, bandwidth allocation, etc., for different types of traffic3. QoS can be implemented at various layers of the network stack and across different network domains.

A company has deployed 200 AP-635 access points. To but is not working as expected What would be the correct action to fix the issue?
Correct Answer:
D
According to the Aruba Campus Access Professional documents1, WPA3- Enterprise is a security mode that supports 802.1X authentication and encryption with either AES-CCM or AES-GCMP. WPA3-Enterprise also optionally adds usage of Suite-B 192-bit minimum-level security suite that is aligned with Commercial National Security Algorithm (CNSA) for enterprise networks2. This mode provides the highest level of security and is suitable for government and financial institutions.
The exhibit shows that the SSID is configured with WPA3-Enterprise (CCM), which uses AES-CCM as the encryption protocol. However, this mode is not compatible with some devices that require CNSA compliance. Therefore, changing the SSID to WPA3-Enterprise (CNSA) would fix the issue and allow all devices to connect to the network.
Refer to the exhibit.
With Core-1. what is the default value for config-revision?
Correct Answer:
A
The default value for config-revision on Core-1 is 0. Config-revision is a parameter that indicates the configuration version of a VSX pair. It is used to synchronize the configuration between the VSX peers and to detect any configuration mismatch. The config-revision value is set to 0 by default on both VSX peers and is incremented by 1 every time a configuration change is made on either peer. The other options are incorrect because they do not reflect the default value of config-revision.
