MAC Caching under the splash page
MAC Caching under the user-role
Wireless Caching under the splash page
MAC Caching under the WLAN

Answer(s): A

Explanation:

MAC Caching is a feature that allows a guest user to bypass the captive portal page after the first authentication based on their MAC address1 MAC Caching can be enabled under the splash page settings in Aruba Cloud Guest2 MAC Caching can improve the user experience and reduce the network overhead by eliminating the need for repeated authentication.

QUESTION: 45

Your customer is having connectivity issues with a newly-deployed Microbranch group The access points in this group are online in Aruba Central, but no VPN tunnels are forming.
What is the most likely cause of this issue?

There is a time difference between the AP and the gateways The gateways should have NTP added
The SSL certificate on the gateway used to encrypt the connection has not been added to the APs trust list
There may be a firewall blocking GRE tunneling between the AP and the gateway
The gateway group is running in automatic cluster mode and should be in manual cluster mode

Answer(s): C

Explanation:

This is the most likely cause of the issue where the access points in a Microbranch group are online in Aruba Central, but no VPN tunnels are forming. A Microbranch group is a group that contains both APs and Gateways and allows them to form VPN tunnels for secure communication. The VPN tunnels use GRE (Generic Routing Encapsulation) as the encapsulation protocol and IPSec as the encryption protocol. If there is a firewall blocking GRE traffic between the AP and the gateway, the VPN tunnels cannot be established. The other options are incorrect because they either do not affect the VPN

tunnel formation or do not apply to a Microbranch group.

QUESTION: 46

Which statements regarding 0SPFv2 route redistribution are true for Aruba OS CX switches? (Select two.)

The "redistribute connected" command will redistribute all connected routes for the switch including local loopback addresses
The "redistribute ospf" command will redistribute routes from all OSPF V2 and V3 processes
The "redistribute static route-map connected-routes" command will redistribute all static routes without a matching deny in the route map "connected-routes".
The "redistribute connected" command will redistribute all connected routes for the switch except local loopback addresses.
The "redistribute static route-map connected-routes" command will redistribute all static routes with a matching permit in the route map "connected-routes-

Answer(s): A,E

Explanation:

These are two correct statements regarding OSPFv2 route redistribution for Aruba OS CX switches. Route redistribution is a process that allows routes from one routing protocol or source to be injected into another routing protocol or destination. OSPFv2 is a link-state routing protocol that supports route redistribution from various sources, such as connected, static, BGP, etc. The "redistribute connected" command will redistribute all connected routes for the switch, including local loopback addresses, into OSPFv2. The "redistribute static route-map connected-routes" command will redistribute all static routes that have a matching permit statement in the route map named "connected-routes" into OSPFv2. The other statements are incorrect because they either do not reflect the correct behavior of route redistribution commands or do not exist as valid commands.

QUESTION: 47

You are configuring an SVI on an Aruba CX switch that needs to have the following characteristics:
· VLANID = 25
. IPv4 address 10 105 43 1 with mask 255 255 255.0
· IPv6 address fd00:5708::f02d:4df6 with a 64 bit prefix length · member of VRF eng
· VRF eng and VLAN 25 have not yet been created
Which command lists will satisfy the requirements with the least number of commands? A)

B)

C)

D)

Option A
Option B
Option C
Option D

Answer(s): C

Explanation:

The other options either use more commands or do not create the VRF or the VLAN.
Option C uses the following commands:
vrf eng: This command creates a VRF named eng and enters the VRF configuration mode.

vlan 25: This command creates a VLAN with ID 25 and enters the VLAN configuration mode. interface vlan 25: This command creates an SVI on VLAN 25 and enters the interface configuration mode.
ip address 10.105.43.1/24 ipv6 address fd00:5780::102d:4df6/64 vrf attach eng: This command assigns an IPv4 address of 10.105.43.1 with a subnet mask of 255.255.255.0 and an IPv6 address of fd00:5780::102d:4df6 with a prefix length of 64 to the SVI, and attaches it to the VRF eng.
