Question # 76

Which two characteristics are associated with 802 1s? (Choose two)

802.1s supports up to 1024 instances of 802.1

802.1 s is a Cisco enhancement to 802.1w.

802.1s provides for faster convergence over 802 1D and PVST+.

CPU and memory requirements are the highest of all spanning-tree STP implementations.

802.1s maps multiple VLANs to the same spanning-tree instance

Question # 79

Which two aspects are considered when designing a dual hub dual DMVPN cloud topology? (Choose two )

will only work with single-tier headend architecture

hub sites must connect to both DMVPN clouds

recommended for high availability

spoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly

requires all sites to have dual Internet connections

Full Access

Question # 80

Which two statements describe the usage of the IS-IS overload bit technique? (Choose two )

lf overload-bit is set on a Level 2 intermediate system, the other Level 2 intermediate systems in the topology will stop using the overloaded IS to forward Level 2 traffic However, the intermediate system can still forward Level 1 traffic

It can be set in intermediate systems (IS-IS routers) to prioritize control plane CSNP packets.

It can be used to automatically synchronize the link-state database between Level 1 intermediate systems

It can be set in intermediate systems (IS-IS routers) to avoid traffic black holes until routing protocols are fully converged after a reload operation.

It can be set in intermediate systems (IS-IS routers) to attract transit traffic from other intermediate systems
