Question 1 Single choice

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 edge should run PIM-SM, while switches at the network core should run PIM-
DM.
B
All switches must use PIM-DM only or all switches must use PIM-SM only for the solution to work.
C
Different interfaces on the same switch can run in different modes, but the mode must match the neighbor.
D
Switches at the network core should run PIM-DM, while switches at the network edge should run PIM-
SM.

Correct answer: B

Question 2 Single choice

A network administrator configures connection rate filtering on interface 1 with the throttle action. Device 1 crosses the threshold and triggers the action.

What does the switch do?

A
It temporarily drops all IP traffic from Device 1 only.
B
It temporarily drops all IP traffic on interface 1.
C
It drops all IP traffic from Device 1 until the host is manually unblocked.
D
It drops all IP traffic on interface 1 until the interface is manually unblocked.

Question 3 Single choice

What is a reason to create a virtual link between two OSPF routers?

A
to permit OSPF to operate between two routers that also run VRRP
B
to create a connection between two areas that are not directly connected to Area 0
C
to permit an OSPF adjacency between two VSF fabrics
D
to monitor connectivity with the neighbor, but not exchange the routing table

Show answer and explanation

Correct answer: B

Question 4 Single choice

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 loop protection with a timeout period.
B
Enable BPDU filtering.
C
Enable both root guard and BPDU protection.
D
Enable BPDU protection with a timeout period.

Correct answer: D

Question 5 Single choice

Refer to the exhibit.

An AOS-Switch has the ACL shown in the exhibit. A network administrator then enters these commands: Switch(config)# mac-access-list standard myACL Switch(config-std-macl)# 25 deny 007d.45cc.0000 0000.0000.ffff

How does this ACL treat these frames:
1 = 007d.45cc.ffff 2 = 007d.45cc.0000

A
It denies both frames.
B
It permits both frames.
C
It denies frame 1 and permits frame 2.
D
It permits frame 1 and denies frame 2.

Correct answer: A

Question 6 Single choice

Refer to the exhibits.

Exhibit 1

Exhibit 2

A network administrator sets up PIM-DM to route traffic from the multicast source to clients in VLAN 24.
The server begins to forward multicasts, and the clients are set up to receive them. However, the multicasts do not reach the clients.

Based on the output, what should the administrator verify?

A
that VLAN 24 on Switch-1 runs both IGMP and PIM-DM
B
that Switch-2 has PIM-DM enabled on VLAN 10
C
that state refreshes are enabled on Switch-2
D
that Switch-1 has selected Switch-2 as its RP for 239.1.1.1

Show answer and explanation

Correct answer: B

Question 7 Single choice

Refer to the exhibit.

An administrator created a backplane stack with the plug-and-play method, and did not alter the default backplane stacking settings. Later, two backplane stacking links failed, as shown in the exhibit.

What happens to the backplane stack after the failures?

A
The standby becomes the commander of its fragment, which remains active. The fragment with the commander becomes inactive.
B
The fragment that contains the commander operates at Layer 2 and layer 3, and the other fragment operates at layer 2 only.
C
The fragment that contains the commander remains active, and the fragment with the standby member is disabled.
D
The standby becomes the commander of its fragment. Both fragments remain active and operate at both Layer 2 and Layer 3.

Question 8 Single choice

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
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.
B
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.
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 1, run the application, and look in the packet capture for a high value DSCP in the IP header.

Correct answer: A

Question 9 Single choice

What is the purpose of the captive portal URL hash key on an AOS-Switch?

A
It specifies the captive portal URL and conceals the setting in the config.
B
It authenticates guest users based on the password the users enter in the portal.
C
It does not let users alter the URL that redirects them to the portal.
D
It encrypts and secures the RADIUS messages that the AOS-Switch sends to ClearPass.
