Which of the following statements regarding Selective Packet Discard(SPD) is correct?
A. Selective Packet Discard(SPD) is a mechanism to drop non-routing packets instead of routing packets when the process level queue is congested.
B. Selective Packet Discard(SPD) is a mechanism to drop normal IP packets instead of VOIP packets when the link is overloaded
C. None of above.
D. Selective Packet Discard(SPD) is a mechanism to drop Frame Relay frames with the DE bit set instead of Frame Relay frames DE bits without being set when the link is overloaded
E. Selective Packet Discard(SPD) is a mechanism to drop packets with low IP precedence instead of packets with high IP precedence when the link is overloaded
What is true regarding Autonomous Systems (AS )?
A. All of the Above
B. AS numbers are assigned by the IANA
C. AS numbers are used by BGP (Border Gateway protocol ) to exchange IP routing information with neighboring AS
D. In the internet, an Autonomous System (AS) is a collection of IP networks and routers under the control
If the OSPF protocol is used to connect customer edge (CE) routers to service provider edge (PE) routers in the VPN backbone, which two options best describe the use of SHAM links?
A. A sham-link is created between any twoo VPN sites that belong to the same OSPF area and share an
OSPF backdoor link
B. A sham-link is seen as an intra-area link between PE routers,an OSPF adjacency is created and database is exchanged
C. A SHAM link is created between two directly connected PE routers so that it is preferred over the low speed backdoor door
D. A SHAM link is part of OSPF network of MPLS-VPN provider.
Assume two routers on the same subnet, R1 and R2, both configured for HSRP. R1 has a priority of 120. Which of the following HSRP interface configurations will always result in the R2 becoming the primary?

C. standby 1 priority 130
D. standby 1 priority 120 preempt
E. standby 1 priority 110 preempt
F. standby 1 priority 110

C. Two LSAs will exist in the network for this destination, and both will be used
D. Only the LSA generated by the highest RID ASBR will exist in the network
What are BCP 38 (Best Common Practices 38)/RFC 2827 Ingress Packet Filtering Principles?
