Q1. Which two values must be identical to allow IS-IS devices to become neighbors? (Choose two.)
A. interface MTU
B. authentication key
C. IP MTU
D. CLNS address
E. NSEL
F. area ID
Answer: A,B
Q2. Which two statements about SoO checking in EIGRP OTP deployments are true? (Choose two).
A. During the import process, the SoO value in BGP is checked against the SoO value of the site map.
B. During the reception of an EIGRP update, the SoO value in the EIGRP update is checked against the SoO value of the site map on the ingress interface.
C. At the ingress of the PE/CE link, the SoO in the EIGRP update is checked against the SoO within the PE/CE routing protocol.
D. At the egress of the PE/CE link, the SoO is checked against the SoO within the PE/CE routing protocol.
E. The SoO is checked at the ingress of the backdoor link.
F. The SoO is checked at the egress of the backdoor link.
Answer: A,B
Explanation:
. SoO checking:
– During the import process the SoO value in BGP update is checked against the SoO value of the site-map attached to VRF interface. The update is propagated to CE only if there is no match (this check is done regardless of protocol used on PE/CE link).
– At reception of EIGRP update, the SoO value in the EIGRP update is checked against the SoO value of site-map attached to the incoming interface. This update is accepted only if there is no match (this check can optionally be done on backdoor router).

Q3. Refer to the exhibit.
Which two statements about this capture are true? (Choose two.)
A. It is set to run for five minutes.
B. It continues to capture data after the buffer is full.
C. It is set to run for a period of 00:03:26.
D. It captures data only until the buffer is full.
E. It is set to use the default buffer type.
Answer: A,B
Q4. DRAG DROP
Drag and drop the argument of the ip cef load-sharing algorithm command on the left to the function it performs on the right.
Answer:
Q5. Which two statements about 6VPE are true? (Choose two.)
A. It allows a service provider to use an existing MPLS network to provide VPN services to IPv6 customers.
B. It uses MP-BGP as the carrier protocol to transport IPv6 connectivity.
C. It provides IPv6 connectivity to MPLS-VPN customers when IPv6 overlay tunneling is also configured.
D. It allows a service provider to use an existing MPLS network to provide global addressing to their IPv6 customers.
E. It requires the configuration of a GRE tunnel tagged with a VLAN ID.
F. It allows a service provider to use an existing L2TPv3 network to provide VPN services to IPv6 customers.
Answer: A,B
Explanation:
The IPv6 MPLS VPN service model is similar to that of IPv4 MPLS VPNs. Service providers who have already deployed MPLS IPv4 VPN services over an IPv4 backbone can deploy IPv6 MPLS VPN services over the same IPv4 backbone by upgrading the PE router IOS version and dual-stack configuration, without any change on the core routers. IPv4 services can be provided in parallel with IPv6 services. IPv6 VPN service is exactly the same as MPLS VPN for IPv4. 6VPE offers the same architectural features as MPLS VPN for IPv4. It offers IPv6 VPN and uses the same components, such as: .
Multiprotocol BGP (MP-BGP) VPN address family .
Route distinguishers .
VPN Routing and Forwarding (VRF) instances .
Site of Origin (SOO) .
Extended community .
MP-BGP

Q6. Refer to the exhibit.
Which two statements about the EEM applet configuration are true? (Choose two.)
A. The EEM applet runs before the CLI command is executed.
B. The EEM applet runs after the CLI command is executed.
C. The EEM applet requires a case-insensitive response.
D. The running configuration is displayed only if the letter Y is entered at the CLI.
Answer: A,D
Explanation:
sync Indicates whether the policy should be executed synchronously before the CLI command executes.
. If the yes keyword is specified, the policy will run synchronously with the CLI command.
. If the no keyword is specified, the policy will run asynchronously with the CLI command.
nocase
(Optional) Specifies case insensitive comparison.
Here we see that the sync knob was enabled so A is correct. However, C is not correct as the nocase argument was not used, so the applet is configured to display the config only if a capital Y is issued.

Q7. Refer to the exhibit.
Why is the host unable to obtain an IP address?
A. IP source guard is configured on the switch port.
B. The DHCP server pool addresses are configured incorrectly.
C. DHCP requests are being blocked.
D. DHCP option 150 is disabled.
Answer: A
Q8. DRAG DROP
Drag and drop the method for refreshing BGP prefixes on the left to the corresponding description on the right.
Answer:
Q9. Refer to the exhibit.
Which BGP feature allows R1 to instruct R2 which prefixes it is allowed to advertise to R1?
A. route refresh
B. Prefix-Based Outbound Route Filtering
C. distribute lists
D. prefix lists
Answer: B
Q10. Refer to the exhibit.
What kind of load balancing is done on this router?
A. per-packet load balancing
B. per-flow load balancing
C. per-label load balancing
D. star round-robin load balancing
Answer: A
Explanation:
Here we can see that for the same traffic source/destination pair of 10.0.0.1 to 14.0.0.2 there were a total of 100 packets (shown by second entry without the *) and that the packets were distributed evenly across the three different outgoing interfaces (34, 33, 33 packets, respectively.
