B.

Eavesdrop prevention should be disabled when port security is in limited-continuous mode.

C.

Port security and loop protection should not be enabled on the same port.

D.

Loop protection should operate in VLAN mode, rather than port mode, when port security is enabled.

Question 11

Question 12

An AOS-Switch needs to be configured to support tunneled node in role-based mode. The Mobility Controller administrators tell the switch administrators that the AOS-Switch will integrate with a cluster of Mobility Controllers. The cluster virtual IP address is 10.1.1.10.

How should switch administrator integrate the AOS-Switch with the cluster?

Options:

A.

Double-check the settings with the Mobility Controller administrators because the planned configuration is incomplete with the switch settings.

B.

Configure the virtual IP address as the tunneled-node-server address, tunneled node will work, but the clustering features will not provide redundancy.

C.

Configure the virtual IP address as the tunneled-node-server address. The switch will automatically learn controller IP addresses to which to tunnel various traffic.

D.

Configure the virtual IP address for the primary tunneled-node-server and an actual controller IP address for the backup tunneled-node-server in order to receive redundancy.

Question 13

A.

both a standard IP ACL and a standard MAC ACL

B.

both a standard IP ACL and an extended MAC ACL

an extended IP ACL only

D.

an extended MAC ACL only

Options:

A.

backplane stacking license

B.

QSFP+ fiber transceivers and MPO cable

C.

D.

QSFP+ fiber transceivers and 40GbE to 10GbE cable splitters

Question 16

Refer to the exhibits.

Exhibit 1

Exhibit 2

Switch-1 has a power issue that causes it to fail. When Switch-1 comes back up, endpoints lose connectivity for a few minutes. The network administrator decides to enter this command on Switch-1:

Switch-1 (config)# vlan 10 vrrp vrid 10 preempt-delay-time 120

Exhibit 2 shows the VRRP configuration just after the change. What is the effect of this change?

Options:

A.

Switch-1 and Switch-2 both become Master in their own VRRP virtual router due to the delay timer mismatch. The mismatch must be fixed.

B.

Switch-1 now waits to take over as Master if it fails and recovers. This should prevent the connectivity issue from occurring again.

C.

Switch-1 experiences an internal error in the VRRP 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.

Question 17

Refer to the exhibit.

Switch-1 and Switch-2 are AOS-Switches, which are iBGP peers. ISP 1 and ISP 2 advertise some routes to the same Internet destinations. Switch-1 and Switch-2 must select between these routes based on AS path length.
