A. IP FRR
B. NSR
C. graceful restart
D. BFD

Q5. An engineer is deploying RTBH. What is necessary routing constraint required for successful implementation?
A. The trigger device must have an iBGP session with all the clusters/route reflectors in the autonomous system.
B. The trigger device must redistribute the static route pointing to a null interface into the IGP process.
C. The no ip reachables command must be issued on the PE router interface under attack.
D. The attacker’s destination IP address must be routed to a null interface.
E. The eBGP sessions need to set the next-hop attribute value to the trigger device loopback interface.

Q6. Two Tier 2 Service Providers are using a Tier 1 Service Provider for transport. MPLS is required between the Tier 2 Service Providers for label switching. In this CSC solution, which label stack is correct?
A. original IP packet, MPLS CSC transport label, MPLS VPN label, and MPLS Tier 2 transport label
B. original IP packet, MPLS Tier 2 transport label, MPLS VPN label, and MPLS CSC transport label
C. original IP packet, MPLS VPN label, MPLS Tier 2 transport label, and MPLS CSC transport label
D. original IP packet, MPLS Tier 2 transport label, MPLS CSC transport label, and MPLS VPN label
Answer: C
Q7. Which information is carried in the OSPFv3 intra-area Prefix LSA?
A. All link-local addresses
B. All IPv6 prefix and topology information that OSPFv2 included in Router LSA and Network LSA
C. List of options associated with the link to all other routers attached to the link
D. All prefix-specific information that OSPFv2 included in Router LSA and Network LSA
Answer: D
Explanation:
OSPFv3's new LSA, the Intra-area Prefix LSA (type 9), handles intra-area network information that was previously included in OSPFv2 type 2 LSAs. It is used in order to advertise one or more IPv6 prefixes. The prefixes are associated with router segment, stub network segment or transit network segment. Intra-area prefix LSAs (type 9) & Inter-Area-Prefix-LSA (type 3) carry all IPv6 prefix information, which, in IPv4, is included in router LSAs and network LSAs.
Q8. Users are complaining of intermittent high packet loss for seconds at a time. The engineer troubleshooting the issue finds that a TenGigE link is bouncing for milliseconds at a time, causing the traffic path to reconverge onto a congested FastEthernet link. What can the engineer do to prevent this service-affecting reconvergence only in the case of momentary link bounces until the link can be repaired?
A. decrease the carrier-delay up on both sides of the link
B. disable keepalives and BFD
C. decrease the carrier-delay down on both sides of the link
D. increase the carrier-delay up on both sides of the link
E. increase the carrier-delay down on both sides of the link
Answer: D
Q9. Two switches are connected back-to-back using two Gigabit Ethernet interfaces. These two interfaces are assigned to a port channel in VLAN trunk mode. Which configuration sequence allows the addition of a new VLAN in this link?
A. Add the VLAN to the port channel only, and remove it from the individual links.
B. Add the VLAN to both the port channel and individual links.
C. Add the VLW to the port channel only, and it will be reflected on the individual links.
D. Add the VLAN to the individual links, and it will be reflected on the port channel.
Answer: C
Q10. Refer to the exhibit.
A network engineer is troubleshooting PTP on Cisco ASR 9000 router. What can be concluded about the interface based on output provided?
A. The interface receives timestamps from a master clock, but the router's clock is not yet synchronized to the master.
B. The interface is aware of a better clock than the one it would advertise if it was in Master state.
C. The interface is not yet ready to participate on PTP.
D. The interface is about to go into Master state.
Answer: A
