An engineer is addressing an IS-IS design issue which is running within the topology. All links are running on FastEthernet, except the link between R5 and R4, which is Gigabit Ethernet. Which statement about the design is true?

Which type of policy does an IPv6 ISATAP tunnel support?

Refer to the exhibit. An engineer is troubleshooting an issue with traffic steering using the color-only automated steering mechanism. BGP is failing to automatically steer traffic into an SR policy with the given color of a route, regardless of the next hop. The layer 2 configuration is correct, and the physical connection between the devices is working normally. Whch additional command sequence must the engineer add to correct the issue?

Refer to the exhibit. Customer A and customer B are connecting through a service provider network with these requirements
* R1 acts as the mapping server to connect 10 0 0.0/30 and 172.16.0.0/30 networks
* R1 and R2 are using nondefault SRG8 range to allocate SID.
* R2 ads as the mapping client for transient traffic originating from customer A Which configuration meets the requirements?

A network engineer recently deployed a wireless network for users at a new office to join video conferences wirelessly. The existing network consists of routers that are configured for EIGRP and BGP. Which are located at several data centers in different physical locations. The engineer configured PIM-SSM within a single domain from a single source. However, during the testing phase, the video conference failed to work for any of the users. The IPs are reachable and firewalls in the network are configured correctly to allow the traffic.
Which action resolves the issue?
