Question #:1 - (Exam Topic 5)
A network engineer wants to allow a temporary entry for a remote user with a specific username and password
so that the user can acess the entire network over the Internet. Which ACL can be used?
A. dynamic
B. standard
C. extended
D. reflexive
Answer: A
Explanation
We can use a dynamic access list to authenticate a remote user with a specific username and password. The
authentication process is done by the router or a central access server such as a TACACS+ or RADIUS server.
The configuration of dynamic ACL can be read

Question #:5 - (Exam Topic 1)
Refer to the exhibit.
At the end of an RSTP election process, which access layer switch port will assume the discarding role?
A. Switch3,port Gi0/2
B. Switch3,port Gi0/1
C. Swrtch4,port fa0/11
D. Switch3,portfa0/12
E. Switch3,port fa0/1
F. Swrtch4, port fa0/2
Answer: C
Explanation
MAC of Switch3 is smaller than that of Switch4) so both ports of Switch3 will be in forwarding state. The
alternative port will surely belong to Switch4. Switch4 will need to block one of its ports to avoid a bridging
loop between the two switches. But how does Switch4 select its blocked port? Well, theanswer is based on the
BPDUs it receives from Switch3. A BPDU is superior than another if it has:1. A lower Root Bridge ID2. A
lower path cost to the Root3. A lower Sending Bridge ID4. A lower Sending Port IDThese four parameters are
examined in order. In this specific case, all the BPDUs sent by Switch3 have the same Root Bridge ID, the

same path cost to the Root and the same Sending Bridge ID. The only parameter left to select the best one is
the Sending Port ID (Port ID = port priority + port index). In this case the port priorities are equal because they
use the default value, so Switch4 will compare port index values, which are unique to each port on the switch,
and because Fa0/12 is inferior to Fa0/1, Switch4 will select the port connected with Fa0/1 (of Switch3) as its
root port and block the other port -> Port fa0/11 of Switch4 will be blocked (discarding role)

Question #:9 - (Exam Topic 3)
Which three statements accurately describe Layer 2 Ethernet switches? (Choose three.)
A. Spanning Tree Protocol allows switches to automatically share VLAN information.
B. Establishing VLANs increases the number of broadcast domains.
C. Switches that are configured with VLANs make forwarding decisions based on both Layer 2 and Layer
3 address information.
D. Microsegmentation decreases the number of collisions on the network.
E. In a properly functioning network with redundant switched paths, each switched segment will contain
one root bridge with all its ports in the forwarding state. All other switches in that broadcast domain will
have only one root port.
F. If a switch receives a frame for an unknown destination, it uses ARP to resolve the address.
Answer: B D E
Explanation
Microsegmentation is a network design (functionality) where each workstation or device on a network gets its
own dedicated segment (collision domain) to the switch. Each network device gets the full bandwidth of the
segment and does not have to share the segment with other devices. Microsegmentation reduces and can even
eliminate collisions because each segment is its own collision domain ->.
Note: Microsegmentation decreases the number of collisions but it increases the number of collision domains.
