An administrator is troubleshooting a newly installed AP43 that is showing as "Disconnected" in the Mist UI. The AP's status LED is blinking yellow seven times repeatedly.
AP LED Status: - Blink Pattern: Yellow, Yellow, Yellow, Yellow, Yellow, Yellow, Yellow (Pause) ...
Repeat
What is the most likely cause of the AP disconnection?

• A.The AP has a bad Ethernet cable.
• B.The AP has an invalid static IP configuration.
• C.The switch port is providing insufficient PoE power.
• D.The AP cannot resolve the Mist cloud hostname via the configured DNS server.

A "Coverage" SLE failure indicates that a client is experiencing low signal strength.
What is the most common solution to this problem?

• A.Increasing the AP's transmit power or adding another AP closer to the user.
• B.Changing the WLAN security type.
• C.Rebooting the DHCP server.
• D.Upgrading the client's device driver.

A client connects to a wireless network, completes the 802.1X authentication, but then fails to obtain an IP address. The "Successful Connects" SLE shows a failure, and the primary classifier is "DHCP." Which two are the most likely causes for this specific failure? (Select all that apply.)

• A.The DHCP server has exhausted its pool of available IP addresses.
• B.The RADIUS server is offline.
• C.The client's signal strength (RSSI) is below the configured coverage threshold.
• D.The client entered an incorrect 802.1X password.
• E.The AP's switch port is missing the correct VLAN trunk configuration, preventing the client's DHCP request from reaching the server.

A user is connected to a WLAN that is secured with WPA3-Personal (SAE). Which of the following statements is true about the security of this user's traffic?

• A.The traffic is not encrypted, but the user is authenticated with a passphrase.
• B.All data frames are encrypted using a key derived from the shared passphrase, and management frames are protected.
• C.Only traffic destined for the internet is encrypted; local network traffic is sent in the clear.
• D.The traffic is encrypted, but the AP's identity is not verified, leaving it vulnerable to honeypot attacks.

A network administrator is reviewing the Marvis Actions dashboard and sees an action for "Bad Cable" affecting a specific AP, `AP-Lobby-01`.
Marvis Actions
--
Category: Layer 1
Action: Bad Cable
Details: AP-Lobby-01 on switch Corp-SW-01 port ge-0/0/5 is experiencing high frame errors.
Recommendation: Please test the cable/port.
What type of data does Marvis use to proactively identify this issue?

• A.DHCP and DNS failure events from clients connected to the AP.
• B.Radio frequency (RF) interference data from the AP's scanning radio.
• C.Frame errors, link statistics, and traffic patterns from the AP's wired Ethernet port.
• D.Client roaming history and SLE metrics.
