In a nonbackbone OSPF area, all traffic that is destined to the Internet is routed by using a default route that is originated by the ABR. Which change in the configuration of the OSPF area type causes traffic from that area that is destined to the Internet to be dropped?
A. The OSPF area changes from NSSA to totally stubby area.
B. The OSPF area changes from NSSA to regular area.
C. The OSPF area changes from stub area to totally stubby area.

NEW QUESTION 26
Refer to the exhibit. When the link between RtrB and RtrC goes down, multicast receivers stop receiving traffic from the source for multicast group 220.127.116.11.Which solution will resolve this?
A. adding a static mroute on RtrB and RtrF
B. adding a static unicast route on RtrB and RtrF
C. creating a GRE tunnel between RtrB and RtrD
D. enabling PIM sparse mode on both ends of the link between RtrB and RtrF
NEW QUESTION 27
Which measure does ISIS use to avoid sending traffic with a wrong MTU configuration?
A. ISIS does not protect from MTU mismatch.
B. MTU value is communicated in ISIS Sequence Number PDUs (SNP), and ISIS adjacency is not established if an MTU mismatch is detected.
C. ISIS uses path MTU discovery as specified in RFC 1063.
D. ISIS uses padding of hello packets to full MTU.
NEW QUESTION 28
Which regular expression will match prefixes from the AS 200 that is directly connected to our AS?
NEW QUESTION 29
Refer to the exhibit. Assuming that the peer is configured correctly and the interface is up, how many neighbors will be seen in the EIGRPv6 neighbor table on this IPv6-only router?
A. one neighbor, which will use a local router-id of 6010. AB8. . /64
B. one neighbor, which will use a local router-id of 6020. AB8. . /64
C. none, because EIGRPv6 only supports authenticated peers
D. none, because of the mismatch of timers
E. none, because there is no EIGRP router ID configured
NEW QUESTION 30
What does a nonzero forwarding address indicate in a type-5 LSA?
A. It indicates that this link-state ID is eligible for ECMP.
B. It indicates that this router should have an OSPF neighbor relationship with the forwarding address before using this link-state ID.
C. It indicates that the receiving router must check that the next hop is reachable in its routing table before using this link-state ID.
D. It indicates that traffic can be directly routed to this next hop in shared segment scenarios where the external route source is directly connected.
NEW QUESTION 31
Which type of EIGRP routes are summarized by the auto-summary command?
A. internal routes that are learned from a peer that is outside the range of local network statements
B. external routes that are learned from a peer that is inside the range of local network statements
C. locally created routes that are outside the range of local network statements
D. external routes that are learned from a peer that is outside the range of local network statements
A. No action is required, since Gig0/0 is not listed with a nondefault hello and hold time.
B. Add the commands ip hello-interval eigrp 1 5 and ip hold-time eigrp 1 15 under interface Gig0/0.
C. Add the commands hello-interval 5 and hold-time 15 under “af-interface Gig0/0” under the address family.
D. Add the commands default hello-interval and default hold-time under the af-interface Gig0/0 statement under the address family.

NEW QUESTION 34
Which statement about the overload bit in IS-IS is true?
A. The IS-IS adjacencies on the links for which the overload bit is set are brought down.
B. Routers running SPF ignore LSPs with the overload bit set and hence avoid blackholing traffic.
C. A router setting the overload bit becomes unreachable to all other routers in the IS-IS area.
D. The overload bit in IS-IS is used only for external prefixes.
A. R2 is directly connected to the receiver for this group and is the winner of an assert mechanism.
B. R2 is directly connected to the receiver for this group, and it forwards the traffic onto Ethernet3/0, but it is forwarding duplicate traffic onto Ethernet3/0.
C. R2 has the A flag (Accept flag) set on Ethernet 3/0. This is fine, since the group is in BIDIR PIM mode.
D. R2 is directly connected to the receiver for this group and is the loser of an assert mechanism.
E. The A flag is set until the SPT threshold is reached for this multicast group.
