Which two options are benefits of EIGRP OTP? (Choose two.)
Answer : BD
Explanation:
EIGRP Over the Top (OTP) allows EIGRP routers to peer across a service provider infrastructure without the SP"™s involvement. In fact with OTP, the provider won"™t see customer routes at all. EIGRP OTP acts as a provider-independent overlay that transports customer data between the customer"™s routers. To the customer, the EIGRP domain is contiguous. A customer"™s EIGRP router sits at the edge of the provider cloud, and peers with another EIGRP router a different location across the cloud. Learned routes feature a next hop of the customer router "" not the provider. Good news for service providers is that customers can deploy EIGRP OTP with their involvement

DRAG DROP -
Drag each OSPFv2 SA parameter on the left to the corresponding description on the right.
Select and Place:
Answer :
Explanation:
Key Identifier (KeyID)
This is an 8-bit unsigned value used to uniquely identify an OSPFv2 SA and is configured either by the router administrator (or, in the future, possibly by some key management protocol specified by the IETF). The receiver uses this to locate the appropriate OSPFv2 SA to use. The sender puts this KeyID value in the OSPF packet based on the active OSPF configuration.
Authentication Algorithm -
This indicates the authentication algorithm (and also the cryptographic mode, such as HMAC) to be used. This information SHOULD never be sent over the wire in cleartext form. At present, valid values are Keyed-MD5, HMAC-SHA-1,HMAC-SHA-256, HMAC-SHA-384, and HMAC-SHA-512.
Authentication Key -
This is the cryptographic key used for cryptographic authentication with this OSPFv2 SA. This value SHOULDnever be sent over the wire in cleartext form. This is noted as "K" in Section 3.3below.
Key Start Accept -
The time that this OSPF router will accept packets that have been created with this OSPF Security Association.
Key Start Generate -
The time that this OSPF router will begin using this OSPF Security
Association for OSPF packet generation.
Key Stop Generate -
The time that this OSPF router will stop using this OSPF Security
Association for OSPF packet generation.
Key Stop Accept -
The time that this OSPF router will stop accepting packets
generated with this OSPF Security Association.
How does EIGRP derive the metric for manual summary routes?
Answer : A
When is it useful to disable split horizon on an EIGRP interface?
Answer : D
Answer : AC
Explanation:
A router that is configured as a stub with the eigrp stub command shares connected and summary routing information with all neighbor routers by default.

Answer : A
Which statement about the RPF interface in a BIDIR-PIM network is true?
Answer : C
Explanation:
RPF stands for "Reverse Path Forwarding". The RPF Interface of a router with respect to an address is the interface that the MRIB indicates should be used to reach that address. In the case of a BIDIR-PIM multicast group, the RPF interface is determined by looking up the Rendezvous Point Address in the MRIB. The
RPF information determines the interface of the router that would be used to send packets towards the Rendezvous Point Link for the group.
