Q1. Refer to the exhibit.
Which two statements are true about the displayed STP state? (Choose two.)
A. The STP version configured on the switch is IEEE 802.1w.
B. Port-channel 1 is flapping and the last flap occurred 1 minute and 17 seconds ago.
C. The switch does not have PortFast configured on Gi0/15.
D. BPDUs with the TCN bit set are transmitted over port channel 1.
Answer: C,D
Explanation:
A port enabled with portfast will not send topology changes when a port goes up or down, but here we see that 296 TCN’s were sent so we know that Gi 0/15 does not have portfast enabled.
TCN’s are sent using BPDU’s over the root port, which we see is port channel 1.
Q2. What is the maximum number of classes that MQC can support in a single policy map?
A. 512
B. 256
C. 128
D. 64
Answer: B
Q3. Which two statements about VRRP are true? (Choose two.)
A. It is assigned multicast address 224.0.0.18.
B. The TTL for VRRP packets must be 255.
C. It is assigned multicast address 224.0.0.9.
D. Its IP protocol number is 115.
E. Three versions of the VRRP protocol have been defined.
F. It supports both MD5 and SHA1 authentication.
Answer: A,B
Q4. Which two options are required parts of an EEM policy? (Choose two.)
A. event register keyword
B. body
C. environment must defines
D. namespace import
E. entry status
F. exit status
Answer: A,B
Explanation:
EEM policies require two parts: the event register keyword and the body. The remaining
parts of the policy are optional: environment must defines, namespace import, entry status,
and exit status (Figure 5).

Q5. Refer to the exhibit.
Which two options are effects of the given configuration? (Choose two.)
A. It sets the data export destination to 209.165.200.227 on UDP port 49152.
B. It enables Cisco Express Forwarding on interface FastEthernet0/0.
C. It configures the export process to include the BGP peer AS of the router gathering the data.
D. It enables NetFlow switching on interface FastEthernet0/0.
E. It sets the data export destination to 209.165.200.227 on TCP port 49152.
Answer: A,D
Explanation:
The “ip flow-export destination 209.165.200.227 49152” command specifies that the data export destination server is 209.165.200.227 using UDP port 49152.
The “ip route-cache flow” command under the fastethernet 0/0 interface enable netflow switching on that interface.
Q6. Refer to the exhibit.
Which two statements about this configuration are true? (Choose two.)
A. Spoke devices will be dynamically added to the NHRP mappings.
B. The next-hop server address must be configured to 172.168.1.1 on all spokes.
C. The next-hop server address must be configured to 192.168.1.1 on all spokes.
D. R1 will create a static mapping for each spoke.
Answer: A,C
Explanation:
NHRP is a client/server model protocol which is defined by RFC2332. The hub is considered to be the Next Hop Server (NHS) and the spokes are considered to be the Next Hop Client (NHC). The hub must be configured as the next-hop server. NHRP provides a mapping between the inside and outside address of a tunnel endpoint. These mappings can be static or dynamic. In a dynamic scenario, a next-hop server (NHS) is used to maintain a list of possible tunnel endpoints. Each endpoint using the NHS registers its own public and private mapping with the NHS. The local mapping of the NHS must always be static. It is important to note that the branch points to the inside or protected address of the NHS server. This scenario is an example of dynamic mappings.

Q7. You are configuring a DHCPv6 client for a DHCPv6 server with the prefix delegation feature. Which option is a result of the interface configuration when you enter the command ipv6 address autoconfig default?
A. a static IPv6 default route pointing to the upstream DHCP server
B. a static IPv6 default route pointing to the upstream DHCP relay
C. a static IPv6 default route pointing to the upstream router
D. a temporary stateless address, formed from the EUI-64 bit address and the prefix from the route advertisement of the upstream router
Answer: A
Q8. What are the three primary components of NetFlow? (Choose three.)
A. Flow caching
B. A flow collector
C. The data analyzer
D. Flow sequence numbers
E. Cisco Express Forwarding
F. Multicast
Answer: A,B,C
Explanation:
NetFlow includes three key components that perform the following capabilities:
. Flow caching analyzes and collects IP data flows entering router or switch interfaces and prepares data for export. It enables the accumulation of data on flows with unique characteristics, such as IP addresses, application, and CoS.
. FlowCollector and Data Analysis captures exported data from multiple routers and filters and aggregates the data according to customer policies, and then stores this summarized or aggregated data. Users can leverage Cisco NetFlow collector as a flow collector, or they can opt for a variety of third-party partner products. A Graphical user interface displays and analyzes NetFlow data collected from FlowCollector files. This allows users to complete near-real-time visualization or trending analysis of recorded and aggregated flow data. Users can specify the router and aggregation scheme and desired time interval.

Q9. Refer to the exhibit.
Which two configuration changes enable the user admin to log in to the device? (Choose two.)
A. Configure the login authentication to be case-insensitive.
B. Configure the user admin with a password and appropriate privileges.
C. Configure the login authentication to be case-sensitive.
D. Modify the configuration to use a named group.
E. Configure additional login authentication under the terminal lines.
Answer: A,B
Explanation:
Usernames and passwords are case-sensitive. Users attempting to log in with an incorrectly cased username or password will be rejected. If users are unable to log into the router with their specific passwords, reconfigure the username and password on the router.

Q10. When the BGP additional-paths feature is used, what allows a BGP speaker to differentiate between the different available paths?
A. The remote BGP peer prepends its own next-hop address to the prefix.
B. A unique path identifier is encoded into a dedicated field to the NLRI.
C. A route distinguisher is appended to the prefix by the receiving BGP speaker.
D. The additional path information is encoded in an extended community.
Answer: B
