HP Aruba Certified Campus Access Associate Exam 認定 HPE6-A85 試験問題 (Q98-Q103):

質問 # 98
Switch A is configured with priority 80 and an IP address of 10.10.10.2/24. Switch B is configured with priority 80 and an IP address of 10.10.10.3/24. Both Switches are configured with VRRP and VID of 10.10.10.1. Which switch will become the master in a normal operation?

A. Switch B is the master.
B. Both switches are masters until one switch fails.
C. Switch A is the master.
D. The configuration is invalid. VRRP will not work when two switches have the same priority.

正解：A

解説：
When VRRP routers have the same priority, the router with the higher real interface IP address becomes the master. Since Switch B has the higher IP address, it becomes the VRRP master during normal operation.

質問 # 99
What is a common use of LLDP for wireless access points?

A. testing the quality of the physical link between the access point and the switch
B. discovery of rogue access points
C. negotiation of PoE power level to be provided to the access point
D. exchange of RF channel information with nearby access points

正解：C

解説：
LLDP (Link Layer Discovery Protocol) is commonly used by network devices, including wireless access points, to negotiate PoE (Power over Ethernet) power levels with the switch they are connected to. This allows the access point to communicate its power requirements to ensure it receives the necessary power for optimal operation.

質問 # 100
What is the logical construct that allows for using disparate and dispersed network infrastructure using a common set of services in a WLAN?

A. Underlay network
B. Overlay network
C. Basic Service Set
D. Wireless distribution system

正解：B

解説：
An overlay network provides a common set of WLAN services independently of the underlying physical network infrastructure. This allows wireless services to operate consistently across disparate and geographically dispersed networks while abstracting the details of the underlying transport network.

質問 # 101
What is a weakness introduced into the WLAN environment when WPA2-Personal is used for security?

A. It uses X 509 certificates generated by a Certification Authority
B. The Pairwise Master Key (PMK) is shared by ail users
C. It does not use the WPA 4-Way Handshake
D. The Pairwise Temporal Key (PTK) is specific to each session

正解：B

解説：
The weakness introduced into WLAN environment when WPA2-Personal is used for security is that 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 , which are both fixed. This means that all users who know PSK can generate PMK without any authentication process. This also means that if PSK or PMK are compromised by an attacker, they can be used to decrypt all traffic encrypted with PTK Pairwise Temporal Key (PTK) is a key that is derived from PMK, 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 random number 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 other options are not weaknesses because:
It uses X 509 certificates generated by a Certification Authority: This option is false because WPA2-Personal does not use X 509 certificates or Certification Authority for authentication. X 509 certificates and Certification Authority are used in WPA2-Enterprise mode, which uses 802.1X and EAP Extensible Authentication Protocol (EAP) is an authentication framework that provides support for multiple authentication methods, such as passwords, certificates, tokens, or biometrics. EAP is used in wireless networks and point-to-point connections to provide secure authentication between a supplicant (a device that wants to access the network) and an authentication server (a device that verifies the credentials of the supplicant). for user authentication with a RADIUS server Remote Authentication Dial-In User Service (RADIUS) is a network protocol that provides centralized authentication, authorization, and accounting (AAA) management for users who connect and use a network service .
The Pairwise Temporal Key (PTK) is specific to each session: This option is false because PTK being specific to each session is not a weakness but a strength of WPA2-Personal. PTK being specific to each session means that it changes periodically during communication based on time or number of packets transmitted. This prevents replay attacks and increases security of data encryption.
It does not use the WPA 4-Way Handshake: This option is false because WPA2-Personal does use the WPA 4-Way Handshake for key negotiation. The WPA 4-Way Handshake is a process that allows the station and the access point to exchange ANonce and SNonce and derive PTK from PMK. The WPA 4-Way Handshake also allows the station and the access point to verify each other's PMK and confirm the installation of PTK.

質問 # 102
What change does a client make when it roams from one access point to another in a WLAN?

A. It changes its association with the new wireless controller's SSID.
B. It changes the SSID to match the SSID on the new access point.
C. It changes the destination MAC address on its 802.11 frames.
D. It changes its default gateway to the IP of the new access point.

正解：C

解説：
When a client roams from one access point to another, it must change the destination MAC address on its
802.11 frames to match the new access point to which it is associated. The SSID does not change since it is typically consistent across an entire WLAN, and the default gateway remains the same as long as the client stays within the same IP subnet. The association to a new access point involves updating the destination MAC address in the frames that the client sends.
