Question 1

You want to configure an MTU of 9198 for a routed lag interface on a CX 6300 switch. Which configuration achieves this?

AOption A

BOption B

COption C

DOption D

Answer : A

In the context of ArubaOS-CX, particularly with the 6300 series switches, setting the MTU on a routed Link Aggregation Group (LAG) interface requires the interface lag id command in the configuration, specifying the LAG interface you're configuring. The ip mtu command is then used to set the desired MTU size for that LAG. Option A correctly shows this configuration process, where the MTU is set to 9198 for the LAG interface, in line with the requirements for routing larger frames, which could be necessary for certain applications or data flows that require jumbo frames.

The information related to the configuration of Aruba switches is consistent with the principles and guidelines found in the technical documentation for the ArubaOS-CX 6300 series switches, which emphasizes the importance of correct MTU settings for network performance and stability.

Question 2

You are troubleshooting a WLAN deployment with APs and gateways set up with an 802.1X tunneled SSIO. End-users are complaining that they can't connect to die enterprise SSID. Which possible AP tunnel states could be the cause of the Issue? (Select two.)

ASM_STATE_RE KEYING

BSM_STATE_SURVIVED

CSM_STATE_CONNECTED

DSM_STATE_SURVIVING

ESM_STATE_CONNECTING

Answer : A, E

When troubleshooting a WLAN with 802.1X tunneled SSID issues, AP tunnel states indicate the status of the connection between the AP and the gateway/controller. The states 'SM_STATE_REKEYING' and 'SM_STATE_CONNECTING' could indicate transitional states where the connection has not been fully established, hence users might face issues connecting to the SSID. 'SM_STATE_REKEYING' implies that the AP is in the process of re-establishing encryption keys, while 'SM_STATE_CONNECTING' indicates that the AP is trying to establish a connection with the controller or gateway. These states could lead to temporary connectivity issues until the state transitions to 'SM_STATE_CONNECTED'.

Question 3

A BGP routing table contains multiple routes to the same destination prefix.

Referring to the table below which route would be marked with a ">" symbol?

AOption A

BOption B

COption C

DOption D

EOption E

Answer : E

In BGP, the route marked with a '>' symbol is the best route that is chosen based on BGP attributes in the following order: highest weight (Cisco-specific), highest local preference, originated by BGP running on the local router, shortest AS path, lowest origin type, lowest MED, eBGP over iBGP, closest IGP neighbor, and lowest BGP router ID. Based on the table provided, Option E would be marked with a '>' symbol as it has the highest local preference of 100 which is a decisive factor in the BGP best path selection process.

Question 4

Which option shows the correct Banawidth Control for 1024 kbps down and 2048 Kops up for the SSID?

AOption A

BOption B

COption C

DOption D

Answer : D

The correct Bandwidth Control settings for 1024 Kbps down and 2048 Kbps up for the SSID are shown in Option D. In Option D, the downstream is set at 1024 Kbps and the upstream at 2048 Kbps, both configured per user, which matches the requested configuration. This setup ensures that each user has a guaranteed bandwidth allocation of the specified rates when connected to the SSID, providing a controlled and predictable user experience.

Question 5

Exhibit.

After configuring VRRP between sw-1 and SW-2. you notice that both switches are showing as active. What could be the reason for this issue?

AVRRP preemptive mode is disabled.

BSW-1 cam reach SW-2 on VLAN 10.

CBoth switches are configured as VRRP 'primary.'

DSW-2 has no priority configurations for VRRP 1.

Answer : C

In VRRP (Virtual Router Redundancy Protocol), only one switch should be the primary (master) for a given virtual IP address, with the other switches being backups. If both switches are showing as active, it suggests a misconfiguration where both are set to act as the primary for the same VRRP group. The exhibits provided indicate that both switches believe they are the active or primary for the VRRP group, which is an incorrect configuration.

Question 6

Your customer's employees connected to a wired network are complaining about a poor user experience. The customer has UXI sensors deployed on their premises. These sensors nave been running for multiple months. They are testing both the wired network (using the wired Interface of each sensor) and the wireless networks. Your customer used the UXI dashboard to find the reason for the poor user experience to find more details, the customer asked you to check the packet captures that have been downloaded from the sensors using the UXI dashboard.

From the zip file downloaded from the UXI sensors, you checked the "datagrams" .pcap file, but you were not able to find any issues How can you explain this?

AThe 'datagrams- pcap file only contains me successful tests Failed tests are contained in the 'datagrams-failed' .pcap file

BThe UXI sensor could not upload the latest test results to the cloud, so the packet capture is outdated

CThe datagrams captured on the physical Ethernet interface are in a different .pcap file.

DThe default filers of the packet captures do not allow tailed tests to be captured by the sensor

Answer : A

It is a common practice to separate successful and failed test results into different files for ease of troubleshooting. If the 'datagrams.pcap' file shows no issues, it's likely because it only contains successful test data, and the failed tests that could explain the poor user experience would be in a different file, such as 'datagrams-failed.pcap.'

Question 7

in a WLAN network with a tunneled SSID. you see the following events in HPE Aruba Networking Central:

The customer asks you to investigate log messages What should you tell them?

AThis indicates a security issue. The client with a MAC address ending with 37 18;0d Is performing a Denial-of-Service attack on your network. You should track down the client and remove it from the network.

BThis is normal, expected behavior. No further actions are needed.
C. This indicates a client WLAN driver issue for the client with a MAC address ending with 37:18
:Od. You should upgrade the client WLAN driver.

DThere is a roaming issue Enable Fast Roaming 802.11r and OKC to resolve the issue.

Answer : B

The event log showing PMK (Pairwise Master Key) and OKC (Opportunistic Key Caching) key add/update and delete operations is indicative of normal client behavior in a WLAN environment. These events are part of the standard process for maintaining client session security and do not necessarily indicate any issue.
