Which network topology is characterized by a link fate-sharing situation?

Refer to the exhibit.

This network is running IS-IS as the single routing protocol and the LSP and SPF timers are
aggressively configured so the network converges in subsecond. The customer reports that
router B had a memory crash and reloaded, which resulted in some packets from the
application being lost. The application servers are behind router G and the end users are behind
router H. Which design change should be made to prevent this packet-loss problem from
reoccurring?

Refer to the exhibit.You are designing MPLS-TE for this network. The links from Perth to Sydney and from Perth to
Adelaide share the same optical fiber in one given segment. Which feature should you
implement to eliminate the risk that a backup tunnel is installed over the same optical fiber as
the primary one?

Which two benefits does using virtual PortChannel technology provide? (Choose two).

You must measure the amount of traffic that a mobile packet gateway produces when mobile
phones access the service provider’s internal applications, rather than the Internet. Backbone
queuing can be properly designed as a result of this analysis. This traffic is in the multiple
Gigabits per second order of magnitude. Which three actions can you take to allow this
visibility? (Choose three.)

You are a network designer who must fine tune the convergence of an IS-IS network. The failure
detection mechanism has been addressed with reliable loss-of-signal at the interface level.
Which three other tools or techniques should be employed to achieve your requirements?
(Choose three.)

To improve the stability of the network and protect it from intrusions, you must design control
plane security. Which two features should you enable as part of this design? (Choose two.)

You are auditing the network design of a PIM BiDir multicast network. Which option is the most
appropriate multicast group source discovery design consideration for this design?

The network architect wants to reduce the OSPF database in the network by using
summarization techniques. In which two places in the network can summarization be applied
to maximum effect? (Choose two.)

Which technique can be used to deploy IPv6 services in an IPv4-only routed backbone
network?
