NEW QUESTION 73
The implementation plan for AOS-Switches calls for to implement port-based tunneled node.
The Aruba Mobility Controllers that will supports the AOS-Switches run software 8.1.
The controllers will also support APs, are managed by Mobility Master, and use clustering.
Which issue with this plan needs to be addressed?
- A. The switches cannot connect to controllers that also support APs.
- B. The controllers must have their software updated before they can support the switches.

Answer: A
NEW QUESTION 74
Refer to the exhibits.
Exhibit 1
Exhibit 2
A company does not require authentication for security, but AOS-Switches are set up to use local MAC authentication (LMA) to assign the correct VLAN and priority to IP phones. IP phones and computers belong to different VLANs. Each device is supposed to connect to a specific port, but sometimes users connect their devices to the wrong ports and cannot receive access without help from IT.
How can a network administrator configure the switches to eliminate this issue?
- A. Add the MAC addresses for computers to the myPhones MAC group.
- B. Apply LMA to all edge switch ports, and set the unauth VLAN to the user VLAN.
- C. Create a user role that applies the user VLAN, and set this role as the initial role.
- D. Set the address limit to 2 on the switch ports that apply LMA.
Answer: A
NEW QUESTION 75
The security policy for the company requires that switches use SNMPv3 and accept all read-only SNMPv2c messages.

- B. Enable SNMPv3 restricted mode
- C. Enable SNMPv3 only operation
- D. Disable SNMPv3 inform timeouts
Answer: D

Answer: C
NEW QUESTION 78
A network administrator can set the OSPF metric-type on an AOS-Switch to Type 1 or Type 2. What is the difference?
- A. A Type 2 metric marks external routes that can be advertised in NSSAs, while a Type 1 metric marks external routes that can only be advertised in normal areas.
- B. A Type 2 metric stays the same as the external route is advertised, while a Type 1 metric increments with internal OSPF link costs.
- C. A Type 2 metric is assigned to multiple external routes that are aggregated together, while a Type 1 metric does not permit external route aggregation.
- D. A Type 2 metric assigns cost 1 to a 100 Gbps link, while a Type 1 metric assigns cost 1 to all links of
100 Mbps or higher.
Answer: B
NEW QUESTION 79
Refer to the exhibits.
Exhibit 1
Exhibit 2
Switch-1 and Switch-2 are configured to provide VRRP in VLAN 2. The default gateway for VLAN 2 is set to the VRRP virtual IP. Client-1 in VLAN 2 cannot ping its default gateway.
Based on the exhibits, what can administrators determine?
- A. This is the expected behavior, and Switch-1 should still be able to route traffic for Client-1.
- B. The VRRP preempt delay time has not yet expired, and administrators should try to ping the gateway again in several minutes.
- C. Preempt mode is enabled on both Switch-1 and Switch-2, so the Master role continues to alternate between them, and the pings go astray.
- D. Switch-1 and Switch-2 have the same virtual router ID. The conflict interferes with connectivity.
Answer: B
NEW QUESTION 80
Refer to the exhibits.
Exhibit 1
Exhibit 2
In the exhibits, VLAN 20 under a device name indicates that the device is configured with that VLAN. The exhibits also indicate whether VLAN 20 is statically configured on each link, either as an untagged or a tagged VLAN. If the link has no label, VLAN 20 is not statically configured on that link.
A network administrator needs to deploy AOS-Switches that use port-based tunneled node. The plan calls for tunneled-node endpoints to be assigned to VLAN 20 and for the Aruba Mobility Controller to handle the tunneled-node traffic at Layer 2. Which exhibit shows the correct plan for VLAN 20 in the wired infrastructure?
- A. D
- B. C
- C. A
- D. B
Answer: D
NEW QUESTION 81
A network administrator needs to find the source of a performance issue. The administrator has seen that interfaces sometimes start to drop many packets, but the issue is intermittent, and the administrator is not sure exactly when it happens. The administrator wants to be alerted when interfaces start to drop packets. The switches already have an SNMP trap server configured on them.
What else should an administrator do on these switches?
- A. Enable debugging to the session
- B. Set the trap server to inform mode
- C. Set up RMON alarms on dropped packet statistics
- D. Enable link change SNMP traps on the switch
Answer: B
NEW QUESTION 82
Refer to the exhibit.
The routing switches shown in the exhibit run OSPF on the links between each other. The commander in the Switch-1 VSF fabric goes down. Traffic is disrupted for several seconds.
What should a network administrator do to support a faster failover in a similar situation?
- A. Create a redundant virtual link between Switch-1 and Switch-2.
- B. Configure echo mode BFD on the VLAN that connects Switch-1 and Switch-2.
- C. Configure graceful restart, or nonstop OSPF, on Switch-1 and Switch-2, with a proper timer.
- D. Add VRRP on the VLAN between Switch-1 and Switch-2.
Answer: B
NEW QUESTION 83
Refer to the exhibit.
A network administrator sets up prioritization for an application that runs between Device 1 and Device 2. However, the QoS for the application is not what the administrator expects.
How can the administrator check if the network infrastructure prioritizes traffic from Device 1 and Device 2?
- A. Set up RMON alarms on the switches that trigger when a high number of packets are dropped. Then, run the application and check for the alarm.
- B. Run a packet capture on Device 1, run the application, and look in the packet capture for a high value DSCP in the IP header.
- C. Clear interface statistics on the switches. Then, run the application and check the interface queue statistics for the switch-to-switch links.
- D. Run a packet capture on Device 2, run the application, and look in the packet capture for a high value DSCP in the IP header.
Answer: D
NEW QUESTION 84
Which benefit is provided by MD5 authentication for BGP?
- A. It verifies that received BGP routes have valid next hop IP addresses.
- B. It protects BGP routing information from eavesdroppers.
- C. It validates that BGP messages arrive from an authorized device.
- D. It enables users to authenticate to a server across BGP AS boundaries.
Answer: C
NEW QUESTION 85
Exhibit
Exhibit 2 shows the VRRP configuration just after the change. What is the effect of this change?
- A. Switch-1 now waits to take over as Master if it fails and recovers. This should prevent the connectivity issue from occurring again.
- B. Switch-1 and Switch-2 both become Master in their own VRRP virtual router due to the delay timer mismatch. The mismatch must e fixed.
- C. Switch-1 experiences an internal error in the VRRRP process. This error causes Switch-2 to take over as Master for VLAN 2.
- D. Switch-1 continues to act as it did before the preempt delay time was set. Administrators must plan additional changes to fix the issue.
