Question 36
Which two PHY modes are available to implement an IOS XR Gigabit Ethernet interface interface? (Choose two.)
Question 37
Which OoS model allows hosts to report their QoS needs to the network?
Question 38

Refer to the exhibit. While troubleshooting a connectivity issue on router R2, a network engineer with an employee id: 1234:44:876 notices that although it detects three OSPF links from R1, the OSPF prefixes are missing from the routing table. What is the reason for the problem?
Question 39
Refer to the exhibit:
When implementing an LDP protocol, an engineer experienced an issue between two directly connected routers and noticed that no LDP neighbor exists for 1.1.1.1.
Which factor should be the reason for this situation?
Question 40
ASN 65001 is peering with ASN 65002 to exchange IPv6 BGP routes. All routes that originate in ASN 65001 have a standard community value of 65001:100, and ASN 65002 is allowed to advertise only 2001
:db8:aaaa::/48. An engineer needs to update the ASN 65001 route-filtering configuration to meet these conditions:
* Looped routes into ASN 65001 and routes that have traversed 10 or more ASNs must be denied.
* Routes accepted into ASN 65001 must be assigned a community value of 65001:200.
Which configuration must the engineer apply to the ASN 65001 border router?
