Question 5

Question
Centralized licensing is not in use on an Aruba based network which has a Master and three local controllers. No APs terminate on the Master controller. Roles and Firewall policies need to be created and applied, hence PEF-NG license is required
Answer
  • Only the master controller since role and firewall policies are created here.
  • Only the local controllers since firewall policies are applied here
  • The master and all three local controllers
  • This isn't the correct license for this purpose, use PEF-VPN license
  • This is not needed because PEF-NG is part of base OS

  • One license is needed on the master and the DMZ local
  • It is distributed by the license server as needed

Question 11

Question
What is the best practice regarding licensing for a backup master to support Master Redundancy in a network without centralized licensing?
Answer
  • Backup master only requires the AP license
  • Supported limits and installed licenses should be the same on primary master and backup Master
  • Licenses are pushed from the primary to the backup Master along with the configuration
  • The Backup Master does not require licenses to support master redundancy
  • On the backup only one license of each typeis needed.

Answer
  • The frame is discarded because of the implicit deny all at the end of the policy.
  • The frame is discarded because of the statement: user host 10.1.1.1 host 10.2.2.2 deny.
  • The frame is accepted because of the statement: user any any permit.

Question 37

Question
View the Server group screen shot above. A company has provisioned the same VAP, AAA and SSID profiles at both its Miami and NY offices.

Image:
8e4483fc-8824-4a01-ade8-57d99ab4a4fd (image/jpg)
Answer
  • The controller recognizes the users Domain and sends the authentication request directly to RadiusMiami.
  • The request is initially sent to RadiusNY1 then RadiusNY1 redirects the controller to send the authentication request to RadiusMiami
  • RadiusNY1 receives the request and returns a deny. No other action is taken.
  • RadiusNY1 receives the request and returns a deny. The authentication request will then be sent to RadiusMiami.
  • The RadiusNY1 sends the request to RadiusMiami that replies to the controller

Question 38

Question

Image:
a7cfc997-44bc-46ed-b48e-96fff1831749 (image/jpg)
Answer
  • The user was placed in the 802.1x authentication default Role guest
  • The user was placed in the initial Role guest
  • Role derivation failed because roles are case sensitive
  • Role derivation failed because the incorrect operation "value-of" was used
  • 802.1x authentication failed so the user was automatically placed in the guest Role

Question 39

Question
View the Server group and User Roles screen shots above. A user associated to an SSID with 802.1x using this server group. RadiusNY returned a standard radius attribute of filter-Id with a value of "employee". What Role will the user get?

  • Merge the controllers into the same mobility domain
  • The IP subnets of all controllers need to be configured to match
  • This cannot be accomplished
  • Create a new domain between a department 1 controller and one of the department 2 controllers

Question 94

A port firewall policy is applied to a trunk port that denies controller access. An "allow all" Vlan firewall policy is applied to VLAN 33 on the same port. A user connected to VLAN 33 on that port attempts to gain access to the controller. Which of the following statements is true?
Answer
  • The Port policy is applied, therefore no controller access
  • The Vlan policy is applied, then the port policy, therefore no controller access
  • The Vlan policy is applied, therefore access to the controller is allowed
  • You cannot place a firewall policy on a Ports Vlan when the Port already has a policy, therefore no controller access
  • When locally connected to a controller's port you always have controller access

Question 95

Question
An access port has been placed in trusted mode. The Vlan on the port is in Untrusted mode. Which of the following statements is true?

Question 97

Question
A port on a controller has been configured as untrusted. No wired access AAA profile or Global AAA profile is configured. When a user connects to that port which of the following statements is true?

  • The user will fall into the default wired access AAA profile and will be given the initial role.
  • Since there is no wired access AAA profile or Global AAA profile the user will be given the logon role.
  • When configuring the port as untrusted, an error message of "no wired access AAA profile exists" Therefore this is an invalid configuration
  • the user is denied all access automatically because no wired access AAA or Global AAA profile is assigned

Question 100

Question
An AP is not communicating with the controller. Upon investigation you find that the AP is not discovering its controller through DNS. Instead, it received a DHCP reply with option 43 specifying the SIP server's IP address. How do you resolve this problem?
Answer
  • Statically configure the AP to ignore Option 43
  • Remove the option 43 configuration on the DHCP server
  • Statically configure the AP to only use DNS resolution and not other dynamic discovery methods
  • After failing option 43 the AP should have proceeded with ADP, therefore the AP is faulty and needs to be replaced
  • The AP should be purged

Question 101

Question
How is an AP redirected to a Local controller after DNS resolution returns the Master's IP address?
Answer
  • Master looks at the AP-Group and CONTROLLER-IP attributes

Question 146

Question
An Aruba controller is configured with the correct IP address and gateway information and is connected to the corporate LAN via a core layer 2 switch.
