質問 1

Which situation requires an AOS-Switch interface to support MAC-based VLANs?

（A）The interface has an extended MAC ACL applied to it in the outbound direction, and it uses VLAN ID as one of the criteria for rules.

（B）The interface is configured to support 802.1X in user-based mode, connects to more than one endpoint at a time, and users are assigned to different dynamic VLANs.

（C）The interface has an extended MAC ACL applied to it in the inbound direction, and it has multiple tagged VLAN assignments.

（D）The interface is configured to support Local MAC Authentication (LMA), authenticates endpoints against a non-default MAC group, and limits the address count to 1.

質問 5

A network administrator needs to configure PIM across several AOS-Switches in the same routing domain.
What correctly describes how they can implement PIM modes?

（A）Switches at the network core should run PIM-DM, while switches at the network edge should run PIM-SM.

（B）Switches at the network edge should run PIM-SM, while switches at the network core should run PIM-DM.

（C）Different interfaces on the same switch can run in different modes, but the mode must match the neighbor.

（D）All switches must use PIM-DM only or all switches must use PIM-SM only for the solution to work.

（A）Unidirectional Link Detection (UDLD)

（B）Spanning Tree Root Guard

（C）MAC Lockdown

（D）Bidirectional Forwarding Detection (BFD)

質問 7

Refer to the exhibit.

Every switch in the exhibit will route traffic. The company requires a topology in which failover for switch-to-switch links is exclusively handled by the routing protocol and occurs as quickly as possible. Which topology should the administrator use?

（A）D

（B）B

（C）C

（D）A

質問 8

A network uses MSTP and has AOS-Switches at the access layer. The company wants edge ports on the access layer switches to meet these criteria:
* They prevent all rogue switches that run STP, RSTP, or MSTP from connecting to the network.
* If a rogue switch connects and is then replaced by a proper endpoint, the port recovers automatically
* without IT staff involvement.
How should the network administrator set up the edge ports to meet these requirements?

（A）Enable BPDU filtering.

（B）Enable BPDU protection with a timeout period.

（C）Enable loop protection with a timeout period.

（D）Enable both root guard and BPDU protection.

質問 9

Refer to the exhibits.

The network administrator enters the commands shown in Exhibit 2, and Switch-1 and Switch-2 exchange keepalive messages. What is the expected behavior if Switch-1 later fails to receive keepalive messages from Switch-2?

（A）After two consecutive missed keep-alive packets, Switch-1 sends SNMP traps, and Link 1 stays up until the issue is fixed.

（B）Switch-1 disables interface 1 for 10 seconds and then re-enables it. The interface continues to be re-enabled and disabled every 10 seconds until the issue is fixed.

（C）Switch-1 disables interface 1 for 10 seconds, and then re-enables it. The same process repeats twice. If the issue persists, the switch disables the interface permanently.

（D）After two consecutive missed keep-alive packets, Switch-1 disables interface 1, and the interface stays disabled until the issue is fixed.

質問 10

Refer to the exhibits.
Exhibit 1

Exhibit 2

Traffic between servers in Area 1 takes a sub-optimal path rather than the link dedicated to VLAN 1000, subnet 10.0.0.0/30. Based on the exhibits, what can administrators do to create a better path for this traffic?

（A）Add a VLAN in OSPF Area 1 on the link between Switch-1 and Switch-2.

（B）Make sure that OSPF is enabled in Area 0 on VLAN 1000 on both Switch-1 and Switch-2.

（C）Add a virtual OSPF link between Switch-1 and Switch-2.

（D）Decrease the OSPF cost on the VLAN 1000 interface on Switch-1 and Switch-2.
