Although I have passed 504, score 923. But I still want to make this clear.
1. With VLAN routing, a switched VLAN corresponds to a(n) ______
a. Bridge group
b. Media interface
c. ISI trunk interface
d. Single routed subnet
e. Spanning-tree branch
why is c, not d?
2. In which transmission method are frames replicated as needed?
a. Unicast
b. Multicast
c. Simulcast
d. Broadcast
The answer is b, but I think a is also right.
3. Applying an outgoing access list to an interface ______.
a. Results in no action taken by the MLS-SE
b. Generates an MLSP message from the MLS-RP to the MLS-SE
c. Purges any entries for flows on that interface and records no new entries
d. Records enable packets only if the administrator sets the MLS RP IP ACL
command on the interface
e. Causes the MLS-SE to retain the MLS cache entries until they age out and
no longer record any new entries
Cheetsheets answer: C.
but I think C is just right on its first statement, the last
statment("records no new entries") is wrong, because just input ACL will
lead all flow come to Router processer by default, not output ACL.
4. Which two statements about VLANs are true? (choose two)
a. A trunk link does not have a native VLAN.
b. A trunk link does not belong to a specific VLAN.
c. All VLANs can be transported on a single trunk link.
d. There are four identification techniques to determine which VLAN a frame
belongs to when it is received on a trunk link.
Cheetsheets answer: bc
my choice: cd
Why d is not right?
5. The router creates a CGMP frame ______.
a. And forwards it to a well-known address, 224.0.0.1
b. And forwards it to a well-known address to which all CGMP switches listen.
c. And forwards it to the rendezvous point to ensure consistent
configurations.
d. And assigns it a TTL equal to or less than the TTL assigned to the
forwarding instance.
e. Containing the request type, the multicast group address, and the actual
MAC addresses of the destination devices.
Cheetsheets answer: b
my answer: e
cgmp message is sent to a well-know address all the switch can receive, but
just the CGMP enable process the frame. Do u agree with me?
