Which two statements about the bgp deterministic-med and bgp always-compare-med commands are true? (Choose two)

• A. Enabling the bgp always-compare-med command ensures the comparison of the MED variable for paths from neighbors in different autonomous systems.
• B. The bgp deterministic-med command is used to influence the BGP route selection process to cause the MED attribute to have higher precedence over the AS path length
• C. The bgp deterministic-med and bgp always-compare-med commands are enabled by defult.
• D. The bgp always-compare command is used to influence the BGP route selection process to cause the MED attribute to have higher precedence over the AS path system.
• E. Enabling the bgp deterministic-med command ensures the comparison of the MED variable when choosing routes advertised by different peers in the same autonomous system.

Which of the following statements is correct regarding PIM Sparse Mode operations?

• A. From the RP, traffic flows down a Source Tree to each receiver
• B. Receivers are "registered" with RP by their first-hop router
• C. It does not support all underlying unicast routing protocols like BGP
• D. It supports shared trees only assuming all hosts want the multicast traffic
• E. Receivers are "joined" to the Shared Tree (rooted the rp) by their local Designated Router (DR)

What are three advantages of PPPoA implementation? (Choose three.)

• A. PPPoA can use the features on the SSG.
• B. NAP and NSP provide secure access to corporate gateways without managing end-toend PVCs. NAP and NSP use Layer 3 routing, Layer 2 Forwarding, or Layer 2 Tunneling Protocol tunnels. Hence, they can scale their business models for selling wholesale service.
• C. The NSP can oversubscribe by deploying idle and session timeouts using an industry standard RADIUS server for each subscriber.
• D. Cisco Service Selection Gateway is not compatible with PPPoA.
• E. If a single IP address is provided to the CPE, and NAT or PAT is implemented, certain applications such as IPTV, which embed IP information in the payload, will not work. Additionally, if an IP subnet feature is used, an IP address also has to be reserved for the CPE.
• F. Only a single session per CPE on one virtual channel (VC). The username and password are configured on the CPE, so all users behind the CPE for that particular VC can access only one set of services. Users cannot select different sets of services, although using multiple VCs and establishing different PPP sessions on different VCs is possible.

The Attribute field within the IS-IS LSP header contains which of the following flags? (Choose four)

• A. IS-Type
• B. Attached (ATT)
• C. Pseudonode (PN)
• D. Fragment (Frag-Nr)
• E. Partition (P)
• F. Overload (LSPDBOL)

What is the purpose of Dual Ring Interconnect with D C for SDH rings?

• A. Protects signals when multiple span switches fail
• B. Protects pre-emptible traffic from being dropped when a ring switch occurs
• C. Protects signals against any combination of link failure in each ring
• D. Protects signals when a ring switch fails
