Company XYZ is currently running IPv4 but has decided to start the transition into IPv6. The initial objective is to allow communication based on IPv6 wherever possible, and there should still be support in place for devices that only support IPv4. These devices must be able to communicate to IPv6 devices as well. Which solution must be part of the design?

• A.  6rd tunneling
• B.  Host-to-host tunneling
• C.  Dual stack
• D.  Address family translation

You were tasked to enhance the security of a network with these characteristics:
A pool of servers is accessed by numerous data centers and remote sites The servers are accessed via a cluster of firewalls The firewalls are configured properly and are not dropping traffic The firewalls occasionally cause asymmetric routing of traffic within the server data center.
Which technology should you recommend to enhance security by limiting traffic that could originate from a hacker compromising a workstation and redirecting flows at the servers?

• A.  Limit sources of traffic that exit the server-facing interface of the firewall cluster with ACLs.
• B.  Poison certain subnets by adding static routes to Null0 on the core switches connected to the pool of servers.
• C.  Deploy uRPF loose mode.
• D.  Deploy uRPF strict mode.

This network is running OSPF and EIGRP as the routing protocols. Mutual redistribution of the routing protocols has been configured on the appropriate ASBRs. The OSPF network must be designed so that flapping routes in EIGRP domains do not affect the SPF runs within OSPF. The design solution must not affect the way EIGRP routes are propagated into the EIGRP domains. Which technique accomplishes the requirement?

• A.  route summarization at the ASBR interfaces facing the OSPF domain
• B.  route summarization on EIGRP routers connecting toward the ASBR
• C.  route summarization on the appropriate ABRs
• D.  route summarization on the appropriate ASBRs
