A) Device profiles
B) Change of authorization
C) Dynamic segmentation
D) Voice VLANs

Question 69

An administrator is managing a network comprised of AOS-CX switches deployed at the aggregation layer. The switches are paired in a VSX stack and run the OSPF routing protocol. The administrator is concerned about how long it takes for OSPF to converge when one of the VSX switches has to reboot. What should the administrator to do speed up the OSPF convergence of the switch that is rebooting?

A) Change the VSX ISL link from an OSPF broadcast link point-to-point.
B) Implement graceful restart on the VSX switches and their neighboring OSPF switches.
C) Decrease the VSX initial synchronization timer on the two VSX switches.
D) Define non-backbone areas on the VSX switches as totally stubby areas.

Question 70

Examine the network topology. Company XYZ has two connections to a service provider (ISP1). Here is the configuration of Router1: Here is the configuration of Router2: Based on configuration of Router1 and Router2, which BGP metric is being manipulated?

A) Weight
B) Multiple exit discriminator
C) Local preference
D) AS path length

Question 71

A company uses NetEdit to manage a network of 700 AOS-CX switches and approximately 1,000 other SNMP-capable devices. Which management solution should the company use to monitor all the devices, as well as see a topology picture of how all the devices are connected together?

A) NetEdit
B) Aruba AirWave
C) Aruba Activate
D) Network Analysis Engine (NAE)

Question 72

Examine the network exhibit. A network administrator is implementing OSPF on a VSX pair of aggregation switches: Agg1 and Agg2. VLANs 10 and 20 are connected to layer-2 access switches. Agg-1 and Agg-2 are configured as the default gateway for VLANs 10 and 20, with active gateway enabled. What is the best practice for configuring OSPF on the aggregation switches and their connection to the Core switch?

A) Define a layer-2 VSX LAG associated with a layer-3 VLAN interface. Enable active gateway for the Layer-3 VLAN.
B) Define separate layer-3 VLAN interfaces between the aggregation and core switches. Enable active forwarding for the Layer-3 VLAN.
C) Define separate layer-3 VLAN interfaces between the aggregation and core switches. Enable active gateway for the Layer-3 VLAN.
D) Define a layer-2 VSX LAG associated with a layer-3 VLAN interface. Enable active forwarding for the Layer-3 VLAN.

Question 73

What is correct regarding the configuration of ACLs on AOS-CX switches?

A) Statements with the log keyword are always processed by the switch CPU.
B) Standard ACLs are used to match on routes when performing route distribution.
C) Wildcard masks are used to match on a range of IP addresses.
D) Numbers 100 through 199 and 2000 through 2999 are used when creating extended ACLs.

Question 74

When comparing PIM-DM and PIM-SM, which multicast components are only found with PIM-SM in multicast routing? (Choose two.)

A) IGMP querier
B) Rendezvous point
C) Bootstrap router
D) Shortest path tree
E) Designated router

Question 75

A network administrator wants to replace older access layer switches with AOS-CX 6300 switches. Which virtual switching technology can the administrator implement with this solution?

A) Both VSF and VSX
B) Only Backplane stacking
C) Only VSF
D) Only VSX

Question 76

What are best practices when implementing VSX on AOS-CX switches? (Choose two.)

A) The ISL lag should use the default MTU size.
B) Timers should be left at their default values.
C) The default system MAC addresses should be used.
D) The keepalive connection should use a direct layer-3 connection.
E) The ISL lag should use at least 10GbE links or faster.

Question 77

When an AOS-CX switch uses a temporary copy of the Configuration State database, what kind of analysis does NetEdit perform to ensure that the configuration is correct?

A) Syntax validation
B) Semantic validation
C) Conformance validation
D) Change validation

Question 78

An administrator wants to drop traffic from VLAN 6 (10.1.6.0/24) to VLAN 5 (10.1.5.0/24), but allow all other traffic. What is correct configuration to accomplish this?

A)
B)
C)
D)

Question 79

A network has an ABR that connects area 0 and 1. A network engineer configures a summarized route for area 0. The ABR is a designated router (DR) for the segment it uses to connect to area 1. Which LSA type is assigned to this route when the summarized route is advertised into area 1 by the ABR?

A) LSA 1
B) LSA 4
C) LSA 3
D) LSA 2

Question 80

What must a network administrator implement in order to run an NAE script on an AOS-CX switch?

A) Deployment
