HPE2-Z39 Online Practice Questions and Answers

An ArubaOS switch has the routing table shown in the exhibit. A network administrator then enters this

command:

Switch (config) # ip route 10.1.8.0/24 10.1.12.8

Switch (config) # ip route 10.1.4.0/24 10.1.12.13

After the administrator enters this command, packets arrive that are destined for 10.1.12.8 and 10.1.12.13.

What does the switch do with this traffic?

A. It drops all of the traffic.

B. It forwards some of the traffic on VLAN 101 and some of the traffic on VLAN 4.

C. It forwards all of the traffic to 10.1.104.2.

D. It forwards some of the traffic to 10.1.101.1 and drops some of the traffic.

What is one characteristic of a spanning tree edge port on an ArubaOS switch?

A. It ignores incoming BPDUs.

B. It stays in Designated role during topology changes.

C. It only forwards traffic in VLANs assigned to the instance 0 (1ST).

D. It connects to a switch that runs MSTP but in a different region.

All switches are ArubaOS switches that currently have the default spanning tree priority. Switch-1 should be the root of the spanning tree If Switch-1 fails. Switch-2 should become root

Which configuration for spanning tree priorities ensures this behavior?

A. priority 15 on Switch-1 and priority 14 on Switch-2

B. priority 0 on Switch-1 and priority 15 on Switch-2

C. priority 0 on Switch-1 and priority 1 on Switch-2

D. priority 15 on Switch-1 and priority 9 on Switch-2

What is one reason to configure a dynamic LACP link aggregation instead of a static link aggregation?

A. so that the link aggregation automatically chooses its operational key

B. so that the link aggregation can detect the system ID and operational key on the other side of each link

C. so that the link aggregation can automatically change a passive LACP interface to active mode

D. so that the link aggregation can include more interfaces with some interfaces on standby

The exhibit shows settings for a WLAN on an Aruba Instant cluster. To which VLAN is wireless user traffic assigned?

A. to the VLAN defined for wireless users in Aruba AirWave

B. to the default VLAN on switches connected to the Instant APs

C. to the default VLAN defined in the System settings in the Instant Ul

D. to the untagged VLAN on switch ports connected to the Instant APs

On an ArubaOS switch, what is the difference between an SNMPv2c community with manager unrestricted rights and an SNMPv2 community with operator unrestricted rights?

A. The manager unrestricted community has read-write access to all managed objects on the switch; the operator unrestricted community has read-write access to some objects but not to any Config objects.

B. The manager unrestricted community uses the Telnet/SSH password assigned to the manager to authenticate SNMP servers: the operator unrestricted community uses the Telnet/SSH password assigned to the operator.

C. The manager unrestricted community has read-write access to the switch, but the operator unrestricted community has read-only access.

D. The manager unrestricted community uses encryption, but the operator unrestricted community uses plaintext communication

What is the effect if a network administrator sets a spanning tree priority on an ArubaOS switch interface?

A. The interface priority helps to determine which switch on the link is elected root.

B. The interface priority determines whether this switch or the connected switch has the Designated port on the link.

C. The interface priority breaks a tie when multiple interfaces offer the same lowest cost path to the root through the same neighbor

D. The interface priority prevents a rogue switch connected to the interface from becoming root.

An ArubaOS switch has an LACP link aggregation with two links. How does the switch balance traffic over the links?

A. It assigns the first conversation (as defined by the load-balancing algorithm) to the first link, the second conversation to the second link, and so on, in a round-robin fashion.

B. It assigns the first packet to the first link, the second packet to the second link, and so on, in a round-robin fashion.

C. It assigns all traffic to the first link until the link reaches a bandwidth threshold; it then assigns traffic to the second link.

D. It assigns each conversation (as defined by the load-balancing algorithm) to a consistent link, based on a hash.

The ArubaOS switches were at default settings. The network administrator configures the VLANs and IP addresses as shown in the exhibit. All inter switch links are untagged for VLAN 1 and tagged for VLANs 11 and 12. There is no additional configuration performed on the switches. The Windows Server and Windows Client are configured to use Switch-1 as their default gateway.

How does this configuration affect the network topology?

A. The Windows Server and Windows Client cannot ping each other; IP routing must be enabled on all switches in the topology.

B. The Windows Server and Windows Client cannot ping each other; the VLANs are tagged incorrectly on one or more ports.

C. The Windows Server and Windows Client can successfully ping each other.

D. The Windows Server and Windows Client cannot ping each other; IP routing must be enabled on Switch-1.

What are two ports with the alternate role?

A. 1 and 2

B. 2 and 4

C. 4 and 25

D. 25 and 26
