Answer: C
What can the administrator do to find the cause of this problem?
A group of users on the same floor of a campus residence experience connectivity problems continuously throughout the morning. The administrator suspects that it is a L1 problem with physical interference.
What can the administrator do to find the cause of this problem?
A . Access a controller’s spectrum analysis data directly from AirWave with Quick Links.
B . Access RAPIDS data from AirWave’s RAPIDS section.
C . Access RAPIDS data from AirWave’s dashboards, under Home.
D . Access a controller’s spectrum analysis data from AirWave’s dashboards, under Home.
Answer: A
What occurs when a cluster member experiences a failure?
Refer to the exhibit.
An administrator configures a cluster with only the members shown in the exhibit. AP load balancing is enabled. There are no other cluster parameters configured .
What occurs when a cluster member experiences a failure?
A . High value sessions are synchronized.
B . APs and clients are fully replicated.
C . Connected users are de-authenticated
D . APs reboot and rejoin the cluster.
Answer: C
Which Aruba Unified Communications and Collaboration (UCC) deployment mode should be used when UCC is disabled on the Mobility Controllers (MCs)?
Which Aruba Unified Communications and Collaboration (UCC) deployment mode should be used when UCC is disabled on the Mobility Controllers (MCs)?
A . Heuristics mode
B . WMM mode
C . ALG mode
D . SDN-API mode
Answer: B
What should the administrator implement to allow the RAP to connect to the MC at the Secondary DMZ site while the outage at the primary site persists?
Refer to the exhibit.
An administrator supports a RAP at a branch office shown in the exhibit. The company has one Mobility Controller (MC) at the Primary DMZ site and one at the Secondary DMZ site. The RAP is configured to connect to only the MC at the Primary DMZ site. A network outage with the ISP at the Primary DMZ site causes the RAP to reboot. Upon reboot, the RAP cannot build a tunnel to the Secondary DMZ site MC because the administrator forgot to add the Second LMS IP address to the AP Group configuration. Once the RAP can successfully connect, the administrator can add the Secondary DMZ MC as a backup LMS to fix the AP Group.
What should the administrator implement to allow the RAP to connect to the MC at the Secondary DMZ site while the outage at the primary site persists?
A . Dynamic discovery through DHCP Option 43
B . Static configuration from apboot mode
C . Dynamic discovery through DHCP Option 60
D . Dynamic discovery through multicast ADP
Answer: B
What should the administrator do to solve this problem?
An administrator defines credentials in the Mobility Master> Configuration> System section to configure a Mobility Master (MM). The administrator then accesses AirWave and adds the MM in Monitor-Only mode. The administrator expects AirWave to automatically discover the Aruba Virtual Mobility Controllers (VMCs) also managed by the MM, but does not see these under APs/Devices> New section in AirWave.
What should the administrator do to solve this problem?
A . Enable Automatic Device Authorization for the Group the Mobility Master belongs to in AirWave.
B . Define AirWave communication parameters for the Virtual Mobility Controllers on the Mobility
Master, and then scan for the Virtual Mobility Controllers in AirWave.
C . Define the AirWave communication parameters on the Virtual Mobility Controllers, and then scan for the Virtual Mobility Controllers in AirWave.
D . Define AirWave communication parameters for the Virtual Mobility Controllers on the Mobility Master, and have AirWave repoll the Mobility Master.
Answer: D
Which AP parameter contains the IP addresses of the cluster members that the AP should use to connect to the cluster?
An administrator supports a cluster of four Aruba Mobility Controllers (MCs) with management addresses of 10.1.100.101, 10.1.100.102, 10.1.100.103, and 10.1.202.181. The administrator can an administrator this cluster, reboots it and accesses apboot mode. The administrator executes the printenv command .
Which AP parameter contains the IP addresses of the cluster members that the AP should use to connect to the cluster?
A . Nodelist
B . Servername
C . Master_ip
D . Cfg_lms
Answer: A
Which solution allows the administrator to use a protocol analyzer to examine the contents of the 802.11 frames between the AP and controller?
An administrator suspects that the network drops frames between a wireless client and an Aruba Mobility Controller (MC). The administrator wants to examine the frames between the AP and the controller to determine if any frames are missing.
Which solution allows the administrator to use a protocol analyzer to examine the contents of the 802.11 frames between the AP and controller?
A . Implement bridge mode
B . Implement decrypt-tunnel mode.
C . Implement GRE mode.
D . Implement split-tunnel mode.
Answer: B
