Question 6 of 33

Refer to the exhibit.

Which technology does the use of bi-directional BPDUs on all ports in the topology support?

RSTP

MST

Bridge Assurance

Loop Guard

Root Guard "Pass Any Exam. Any Time." - www.actualtests.com 56

UDLD

Correct Answer: C

Spanning Tree Bridge Assurance -

Bridge Assurance (BA) can help protect against bridging loops where a port becomes designated because it has stopped receiving BPDUs. This is similar to the function of loop guard.

Question 7 of 33

Which command enables L2 QoS support in all VLANs (including the native VLAN)?

switchport priority extend cos

mls qos trust dscp

mls qos rewrite ip dscp

switchport trunk native vlan tag

Correct Answer: A

The command 'switchport priority extend cos' is used to enable Layer 2 Quality of Service (QoS) support for VLANs on a switchport. This command extends the Class of Service (CoS) values to all incoming frames on the switchport, including those from the native VLAN. This ensures all VLANs, including the native VLAN, have Layer 2 QoS support.

Question 8 of 33

Refer to the exhibit.

Which two pieces of information in this Wireshark capture indicate that you are viewing EIGRP traffic? (Choose two.)

the header length

the protocol number "Pass Any Exam. Any Time." - www.actualtests.com 187

the destination address

the Class Selector

the source address

the header checksum

Correct Answer: B, C

EIGRP uses protocol number 88, which can be identified as EIGRP in the Wireshark capture. Additionally, the destination IP address 224.0.0.10 is a multicast address used by EIGRP to send routing information to all EIGRP routers on a network segment. These two pieces of information confirm that the traffic is related to EIGRP.

Question 10 of 33

Refer to the exhibit.

Which statement is true?

R2 is directly connected to the receiver for this group and is the winner of an assert mechanism.

R2 is directly connected to the receiver for this group, and it forwards the traffic onto Ethernet3/0, but it is forwarding duplicate traffic onto Ethernet3/0.

R2 has the A flag (Accept flag) set on Ethernet 3/0. This is fine, since the group is in BIDIR-PIM mode.

R2 is directly connected to the receiver for this group and is the loser of an assert mechanism.

The A flag is set until the SPT threshold is reached for this multicast group.

Correct Answer: A

In the exhibit, R2 shows (*, 225.1.1.1) and (10.1.4.7, 225.1.1.1) as the entries. The asterisk (*) in the (*, 225.1.1.1) entry represents the shared tree, indicating that R2 is the router that is currently forwarding traffic from the RP to the receiver. Since there is no other router indicated as forwarding traffic to this group, R2 is the winner of the assert mechanism, forwarding traffic to the group through Ethernet3/0.
