QUESTION NO:5
Refer to the exhibit.
A small enterprise connects its office to two ISPs, using separate T1 links. A static route is used
for the default route, pointing to both interfaces with a different administrative distance, so that one
of the default routes is preferred.
Recently the primary link has been upgraded to a new 10 Mb/s Ethernet link.
After a few weeks, they experienced a failure. The link did not pass traffic, but the primary static
route remained active. They lost their Internet connectivity, even though the backup link was
operating.
Which two possible solutions can be implemented to avoid this situation in the future? (Choose
two.)
A. Implement HSRP link tracking on the branch router R1.
B. Use a track object with an IP SLA probe for the static route on R1.
C. Track the link state of the Ethernet link using a track object on R1.
D. Use a routing protocol between R1 and the upstream ISP.
Answer: B,D
Explanation:
Interface Tracking
Interface tracking allows you to specify another interface on the router for the HSRP process to
monitor in order to alter the HSRP priority for a given group.
If the specified interface’s line protocol goes down, the HSRP priority of this router is reduced,
allowing another HSRP router with higher priority can become active (if it has preemption
enabled).
To configure HSRP interface tracking, use the standby [group] track interface [priority] command.
When multiple tracked interfaces are down, the priority is reduced by a cumulative amount. If you
explicitly set the decrement value, then the value is decreased by that amount if that interface is
down, and decrements are cumulative. If you do not set an explicit decrement value, then the
value is decreased by 10 for each interface that goes down, and decrements are cumulative.
The following example uses the following configuration, with the default decrement value of 10.
Note: When an HSRP group number is not specified, the default group number is group 0.
interface ethernet0
ip address 10.1.1.1 255.255.255.0
standby ip 10.1.1.3
standby priority 110
standby track serial0
standby track serial1
The HSRP behavior with this configuration is:
0 interfaces down = no decrease (priority is 110)
1 interface down = decrease by 10 (priority becomes100)
2 interfaces down = decrease by 10 (priority becomes 90)

QUESTION NO:13
Which two statements are true about traffic shaping? (Choose two.)
A. Out-of-profile packets are queued.
B. It causes TCP retransmits.
C. Marking/remarking is not supported.

E. It uses a single/two-bucket mechanism for metering.
Answer: A,C

QUESTION NO:15
Which three options are considered in the spanning-tree decision process? (Choose three.)
A. lowest root bridge ID
B. lowest path cost to root bridge
C. lowest sender bridge ID
D. highest port ID
E. highest root bridge ID
F. highest path cost to root bridge
Answer: A,B,C
Explanation:
Configuration bridge protocol data units (BPDUs) are sent between switches for each port.
Switches use s four step process to save a copy of the best BPDU seen on every port. When a
port receives a better BPDU, it stops sending them. If the BPDUs stop arriving for 20 seconds
(default), it begins sending them again.
Step 1 Lowest Root Bridge ID (BID)
Step 2 Lowest Path Cost to Root Bridge
Step 3 Lowest Sender BID
Step 4 Lowest Port ID

QUESTION NO:24
Refer to the exhibit.
R1 is not learning about the 172.16.10.0 subnet from the BGP neighbor R2 (209.165.202.130).
What can be done so that R1 will learn about this network?
A. Disable auto-summary on R2.
B. Configure an explicit network command for the 172.16.10.0 subnet on R2.
C. Subnet information cannot be passed between IBGP peers.
D. Disable auto-summary on R1.
Answer: B
Explanation:
By default, BGP does not accept subnets redistributed from IGP. To advertise and carry subnet
routes in BGP, use an explicit network command or the no auto-summary command. If you disable
auto-summarization and have not entered a network command, you will not advertise network
routes for networks with subnet routes unless they contain a summary route.

addresses on a point-to-point link?
A. EIGRPv6 will form a neighbor relationship.
B. EIGRPv6 will not form a neighbor relationship.
C. EIGRPv6 will form a neighbor relationship, but with the log MSG: “EIGRPv6 neighbor not on a
common subnet.”
D. EIGRPv6 will form a neighbor relationship, but routes learned from that neighbor will not be
installed in the routing table.

QUESTION NO:32
Which two tunneling techniques support IPv6 multicasting? (Choose two.)
A. 6to4
B. 6over4
C. ISATAP
D. 6PE
E. GRE
Answer: B,E
Explanation:
When IPv6 multicast is supported (over a 6to4 tunnel), an IPv6 multicast routing protocol must be
used
Restrictions for Implementing IPv6 Multicast
IPv6 multicast for Cisco IOS software uses MLD version 2. This version of MLD is fully backward-
compatible with MLD version 1 (described in RFC 2710). Hosts that support only MLD version 1
will interoperate with a router running MLD version 2. Mixed LANs with both MLD version 1 and
MLD version 2 hosts are likewise supported.
IPv6 multicast is supported only over IPv4 tunnels in Cisco IOS Release 12.3(2)T, Cisco IOS
Release 12.2
(18)S, and Cisco IOS Release 12.0(26)S.
When the bidirectional (bidir) range is used in a network, all routers in that network must be able to
understand the bidirectional range in the bootstrap message (BSM).
IPv6 multicast routing is disabled by default when the ipv6 unicast-routing command is configured.
On Cisco Catalyst 6500 and Cisco 7600 series routers, the ipv6 multicast-routing also must be
enabled in order to use IPv6 unicast routing

QUESTION NO:37
Which command can be used on a PE router to connect to a CE router (11.1.1.4) in VRF red?
A. telnet 11.1.1.4 /vrf-source red
B. telnet 11.1.1.4 source /vrf red
C. telnet 11.1.1.4 /source vrf red
D. telnet 11.1.1.4 /vrf red
E. telnet 11.1.1.4 vrf red
Answer: D
Explanation:
Telnetting can be done through the VRF using the Management Ethernet interface. In the
following example, the router telnets to 172.17.1.1 through the Management Ethernet interface
VRF:
Router# telnet 172.17.1.1 /vrf Mgmt-intf
