Q1. Refer to the exhibit.
R2 is mutually redistributing between EIGRP and BGP.
Which configuration is necessary to enable R1 to see routes from R3?
A. The R3 configuration must include ebgp-multihop to the neighbor statement for R2.
B. The R2 BGP configuration must include bgp redistribute-internal.
C. R1 must be configured with next-hop-self for the neighbor going to R2.
D. The AS numbers configured on R1 and R2 must match.
Answer: B
Explanation:
Whenever you redistribute from BGP to something else, BGP will only advertise externally learned routes. To allow the redistribution of iBGP routes into an interior gateway protocol such as EIGRP or OSPF, use the bgp redistribute-internal command in router configuration mode.
Q2. What is the maximum number of secondary IP addresses that can be configured on a router interface?
A. 1
B. 2
C. 4
D. 1024
E. 65535
F. no limit to the number of addresses
Answer: F
Explanation:
From “IP Routing Frequently Asked Questions”
Q. What are the maximum number of secondary IP addesses that can be configured on a router interface?

Q3. Which three types of address-family configurations are supported in EIGRP named mode? (Choose three.)
A. address-family ipv4 unicast
B. address-family vpnv4
C. address-family ipv6 unicast
D. address-family ipv6 multicast
E. address-family vpnv6
F. address-family ipv4 multicast
Answer: A,C,F
Q4. DRAG DROP

Answer:
Q5. You are configuring a DMVPN hub to perform CBWFQ on a per-spoke basis. Which information is used to identify the spoke?
A. the NHRP network ID
B. the spoke tunnel source IP
C. the spoke tunnel interface IP address
D. the NHRP group
Answer: D
Q6. Which IPv6 tunneling mechanism requires a service provider to use one of its own native IPv6 blocks to guarantee that its IPv6 hosts will be reachable?
A. 6rd tunneling
B. automatic 6to4 tunneling
C. NAT-PT tunneling
D. ISATAP tunneling
E. manual ipv6ip tunneling
F. automatic 4to6 tunneling
Answer: A
Q7. Which statement is true regarding UDLD and STP timers?
A. The UDLD message timer should be two times the STP forward delay to prevent loops.
B. UDLD and STP are unrelated features, and there is no relation between the timers.
C. The timers need to be synced by using the spanning-tree udld-sync command.
D. The timers should be set in such a way that UDLD is detected before the STP forward delay expires.
Answer: D
Explanation:
UDLD is designed to be a helper for STP. Therefore, UDLD should be able to detect an unidirectional link before STP would unblock the port due to missed BPDUs. Thus, when you configure UDLD timers, make sure your values are set so that unidirectional link is detected before “STP MaxAge + 2xForwardDelay” expires.

Q8. 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
Q9. Which statement describes the difference between a stub area and a totally stub area?
A. The ABR advertises a default route to a totally stub area and not to a stub area.
B. Stub areas do not allow LSA types 4 and 5, while totally stub areas do not allow LSA types 3, 4, and 5.
C. Totally stub areas allow limited external routes in the area via a special type 7 LSA, while stub areas do not.
D. Stub areas do not allow external LSAs, ASBR summary LSAs, or summary LSAs with the exception of a default route originated by the ABR via a summary LSA.
Answer: B
Explanation:
. Standard areas can contain LSAs of type 1, 2, 3, 4, and 5, and may contain an ASBR. The backbone is considered a standard area.
. Stub areas can contain type 1, 2, and 3 LSAs. A default route is substituted for external routes.
. Totally stubby areas can only contain type 1 and 2 LSAs, and a single type 3 LSA. The type 3 LSA describes a default route, substituted for all external and inter-area routes.
. Not-so-stubby areas implement stub or totally stubby functionality yet contain an ASBR. Type 7 LSAs generated by the ASBR are converted to type 5 by ABRs to be flooded to the rest of the OSPF domain.
