2. While troubleshooting a network outage, you discover that an employee brought a switch from home into
the office to connect additional equipment to the network. In order to increase his speed, he connected this
switch to both network ports in his office, resulting in a bridge loop. Which of these can you implement to
prevent future occurrences of this issue?
A. RSTP
B. root guard
C. BPDU guard
D. GLBP

5. When implementing MPLS VPNs between CE and PE routers, which of these statements is correct?
A. If using IS-IS as the PE-CE routing protocol, no redistribution is required.
B. If using static routes between the CE and PE routers, no redistribution of other VPN routes is required.
C. If the PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required.
D. If RIP is the routing protocol that is used between the PE-CE routers, no redistribution is required, but
any other protocol will require redistribution.
E. If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other
protocol or static route will require redistribution.
Answer: C
6. You would like to log messages up to the severity level "Notification." Which three of these commands
will you need to issue in order to enable syslog messages to be sent to the syslog server at the IP address
10.1.5.5? (Choose three.)
A. logging on
B. logging host 10.1.5.5
C. logging trap notifications
D. logging syslog notifications
E. logging monitor notifications
F. logging console notifications
Answer: ABC
7. Refer to the exhibit. What is the HSRP state and priority of this interface after HSRP reaches its steady
state?

Answer: D
8. While your MPLS core is using Cisco routers, the core of a company you have acquired is not. After
extending your MPLS VPN networks by integrating the cores, you discover that the end-to-end LPS path
between PE routers cannot be established.
Which of the following may have caused this problem?
A. the MTUs do not match
B. the BGP protocol versions do not match
C. MPLS is not supported between different vendors
D. MP-BGP is not supported between different vendors
E. you are using Cisco proprietary TDP in your existing core
Answer: E
9. You are troubleshooting an issue which is causing full-sized packets entering the MPLS cloud to be
dropped. You have discovered that one of the switches in the MPLS core is not a Cisco switch, but
otherwise the MPLS MTU size is set to 1508 bytes on the routers. Based on this information, which of these
may be the reason the packets are being dropped?
A. no switches support oversized packets
B. by definition, the maximum MTU is 1500 bytes
C. the switch on your MPLS core that was not produced by Cisco does not support oversized packets
D. in this situation, the MTU setting is irrelevant; in MPLS the maximum acceptable IP packet size is 1492
bytes
E. as MPLS VPN labeling increases the size of the packet by 8 bytes, the IP MTU should have been
changed to 1508

10. Refer to the exhibit. Which two of these events will be the result of issuing the above command?
(Choose two.)
A. A 64-bit IPv4 prefix will be created.
B. The route distinguisher will be used to indicate VPN membership.
C. Extended BGP communities will be used to encode route distinguishers.
D. A 96-bit VPNv4 prefix will be created and propagated across the IP network.
E. The route distinguisher is 64 bits and will be prepended to an existing IPv4 route to make it globally
unique.
Answer: DE
11. Refer to the exhibit. You want to minimize the downtime that results from supervisor engine switchovers
on Cisco 6500 Series Switches and Cisco 7600 Series Routers. To achieve this, you are considering
deploying a Cisco Nonstop Forwarding with Stateful Switchover solution using OSPF.
In the exhibit you can see the output of the show ip ospf neighbor detail command. Which trait of systems
using Cisco Nonstop Forwarding with Stateful Switchover and OSPF is shown in the exhibit output and will
impact your plan?
A. Stateful Switchover for Cisco Nonstop Forwarding only works with BGP.
B. Stateful Switchover for Cisco Nonstop Forwarding must be configured on all adjacent routers.
C. Cisco Nonstop Forwarding with Stateful Switchover helper mode is not supported on the adjacent router.
D. Cisco Nonstop Forwarding with Stateful Switchover helper mode for OSPF has been standardized and is
supported on the adjacent router.
