1. What is the purpose of an explicit "deny any" statement at the end of an ACL?
A. none, since it is implicit
B. to enable Cisco IOS IPS to work properly; however, it is the deny all traffic entry that is actually required
C. to enable Cisco IOS Firewall to work properly; however, it is the deny all traffic entry that is actually required
D. to allow the log option to be used to log any matches
E. to prevent sync flood attacks
F. to prevent half-opened TCP connections
Answer: D

2. Which of these is mandatory when configuring Cisco IOS Firewall?
A. Cisco IOS IPS enabled on the untrusted interface
B. NBAR enabled to perform protocol discovery and deep packet inspection
C. a route map to define the trusted outgoing traffic
D. a route map to define the application inspection rules
E. an inbound extended ACL applied to the untrusted interface
Answer: E

3. Which statement correctly describes the disabling of IP TTL propagation in an MPLS network?
A. The TTL field from the IP packet is copied into the TTL field of the MPLS label header at the ingress edge LSR.
B. TTL propagation cannot be disabled in an MPLS domain.
C. TTL propagation is only disabled on the ingress edge LSR.
D. The TTL field of the MPLS label header is set to 255.
E. The TTL field of the IP packet is set to 0.
Answer: D

4. Two routers configured to run BGP have been connected to a firewall, one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer, including the correct BGP session endpoint addresses and the correct BGP session hop-count limit (EBGP multihop). What is a good first test to see if BGP will work across the firewall?
A. Attempt to TELNET from the router connected to the inside of the firewall to the router connected to the outside of the firewall. If telnet works, BGP will work, since telnet and BGP both use TCP to transport data.
B. Ping from the router connected to the inside interface of the firewall to the router connected to the outside interface of the firewall. If you can ping between them, BGP should work, since BGP uses IP to transport packets.
C. There is no way to make BGP work across a firewall without special configuration, so there is no simple test that will show you if BGP will work or not, other than trying to start the peering session.
D. There is no way to make BGP work across a firewall.
Answer: A

5. Spanning Tree Protocol IEEE 802.1s defines the ability to deploy which of these?
A. one global STP instance for all VLANs
B. one STP instance for each VLAN
C. one STP instance per set of VLANs
D. one STP instance per set of bridges
Answer: C

6. Refer to the exhibit. In this network, R1 has been configured to advertise a summary route, 192.168.0.0/22, to R2. R2 has been configured to advertise a summary route, 192.168.0.0/21, to R1. Both routers have been configured to remove the discard route (the route to null created when a summary route is configured) by setting the administrative distance of the discard route to 255.
What will happen if R1 receives a packet destined to 192.168.3.1?
562351331.gif
A. The packet will loop between R1 and R2.
B. It is not possible to set the administrative distance on a summary to 255.
C. The packet will be forwarded to R2, where it will be routed to null0.
D. The packet will be dropped by R1, since there is no route to 192.168.3.1.
Answer: A

7. Refer to the exhibit. In this network, R1 is configured not to perform autosummarization within EIGRP. What routes will R3 learn from R2 through EIGRP?
615795811.gif
A. 172.30.1.0/24 and 10.1.2.0/24; EIGRP only performs autosummarization at the edge between two major networks.
B. 172.30.0.0/16 and 10.1.2.0/24; R2 will perform autosummarization, although R1 will not.
C. Since R2 is configured without autosummarization, it will not propagate the 172.30.1.0/24 route.
D. 172.30.0.0/8 and 10.0.0.0/8.
Answer: A

8. The classic Spanning Tree Protocol (802.1D  1998) uses which sequence of variables to determine the best received BPDU?
A. 1) lowest root bridge id, 2) lowest sender bridge id, 3) lowest port id, 4) lowest root path cost
B. 1) lowest root path cost, 2) lowest root bridge id, 3) lowest sender bridge id, 4) lowest sender port id
C. 1) lowest root bridge id, 2) lowest sender bridge id, 3) lowest root path cost 4) lowest sender port id
D. 1) lowest root bridge id, 2) lowest root path cost, 3) lowest sender bridge id, 4) lowest sender port id
Answer: D
