Answer:

Q3. Which statement about the benefits of MPLS PHP is true? 

A. PHP is implemented to increase the performance on the egress edge LSR. PHP allows the egress edge LSR to perform only one lookup to route the IP packet based on destination IP address and routing table. 

B. PHP is implemented to increase the performance on the egress edge LSR. PHP enables the egress edge LSR to perform only one lookup based on the ingress label. 

C. PHP is implemented to increase the performance on the egress edge LSR. PHP enables the egress edge LSR to perform two lookups, first lookup based on the ingress label and a second route lookup based on the destination IP address. 

D. PHP is implemented to increase the performance on the LSR (P routers). PHP enables the LSR (P routers) to perform only one lookup based on the ingress label. 

E. PHP is implemented to increase the performance on the LSR (P routers). PHP enables the LSR (P routers) to perform only one route lookup based on the destination IP address. 

F. PHP is implemented to increase the performance on the LSR (P routers). PHP enables the LSR (P routers) to perform two lookups, first lookup based on the ingress label and a second route lookup based on the destination IP address. 

G. PHP is implemented to increase the performance on the ingress edge LSR. PHP enables the ingress edge LSR to perform only one lookup based on the ingress label.

A. Enable a wide-style IS-IS metric. 

B. Enable a narrow-style IS-IS metric. 

C. Change the default auto-cost reference bandwidth to a higher value. 

D. Change the default IS-IS metric on each of the router interfaces to better correspond to the interface bandwidth. 

E. Change the interface bandwidth by using the bandwidth interface configuration mode command. 

Answer:
