Q.17 What is NOT a BGP attribute?
A. Origin
B. Weight
C. Local_pref
D. Community
E. Cluster_list
Answer: B
Original answer was E Cluster_List is not a BGP attribute, ABCD are.
However Actually I am not sure that weight is an attribute. It is set using the set weight command yet in
Internet routing
Architectures page 116 (I believe) it does not show weight as an attribute.
Table 5-2. Attribute Type Codes
ORIGIN Well-known mandatory, Type code 1 RFC 1771 LOCAL_PREF Well-Known discretionary, Type code 5 RFC 1771
COMMUNITY Optional transitive, Type 8 RFC 1997 Cluster List Optional nontransitive, Type code 10 RFC 1966

B. With passive mode FTP, both the control and data TCP sessions are initiated from the client.
C. With active mode FTP, the server used the “PORT” command to tell the client on which port it
wished to send the data.
D. For both active and passive mode FTP, the control session on the server always uses TCP port 21,
and the data session always uses TCP port 20.
Answer: A, B Q.23 A network administrator wants an IP static route to point to a backup link,
but only if the same route is not available via a dynamic routing protocol. How would this be
accomplished?
A. Create a static route with a lower administrative distance than the dynamic protocol.
B. Create a static route with a higher administrative distance than the dynamic protocol.
C. Create a static route with a lower metric than the dynamic protocol.
D. Create a static route with the floating-static keyword.

Answer: B Explanation: Configuring SR/TLB involves the configuration of SRB and transparent
bridging An additional command ties in the SRB domain with the transparent bridged domain:
source-bridge transparent ring-group pseudo-ring bridge-number tb-group
The arguments are as follows:
. • ring-group—The virtual ring group number created with the source-bridge ring-group command.
.• pseudo-ring:—A virtual ring group number created for the transparent bridge group. The Token Ring side
.sends frames to this ring number to reach the host in the transparent bridge side.
.• bridge-number:—A bridge number is assigned for the bridge between the virtual ring group and the
pseudo
.ring.
. • tb-group:—The transparent bridge group number configured with the bridge-group command.
