Which of the following describes the serial connection between two routers using the High-level Data Link Control (HDLC) protocol?
1. Synchronous or asynchronous bit-oriented transmission using a universal frame format
2. Synchronous bit-oriented transmissions using a frames format that allows flow control and error detection
3. Asynchronous bit-oriented transmissions using a frame format derived from the synchronous Data-Link Control (SDLC) protocol
4. Asynchronous bit-oriented transmissions using a v.35 DTE/DCE interface
Why are Frame Relay paths referred to as virtual?
1. There are no dedicated circuits to and from the Frame Relay carrier
2. Frame RElay PVCs are created and discrded on demand
3. The connections between PVC endpoints act like dialup circuits
4. There are no dedicated circuits inside the Frame Relay carrier cloud
Which statement accurately describes the split-horizon problem with regard to a multipoint topology?
1. Split horizon must be disabled for all non-IP protocols
2. Split horizon creates IP routing loops in miltipoint domains
3. Split horizon does not apply to broadcast, so it does not protect protocols that use broadcst updates
4. Split horizon prevents any interface from accepting a valid update and forwarding to all the other interfaces
If an authentication protocol is configured for PPP operation, when is the client or user workstation authenticated?
1. Before link establishment
2. During the link establishment phase
3. Before the networks layer protocol configuration begins
4. After the networks layer protocol configuration has ended
What reliability advantage dos Framfe Relay offer over leased lines?
1. Framef Relay access circuits are higher-graade circuits than leased lines
2. The pathways for virtual circiuts inside the carrier are meshed
3. From end to end, a single virtual circuit uses a fixed error-checked path
4. Frame Relay uses more-sophisticated arror-detection methods
Why is Frame Relay more cost-effective than leased lines? (choose two)
1. Time division multiplexing
2. It uses less equipment
3. Optimized packet routing
4. It shares bandwidth across a large customer base
5. Dynamic IP addressing
Why are Network Control Protocols used in PPP?
1. To establish and terminate data links
2. To provide authentication capabilities to PPP
3. To manage networks congestion and to allow quality testing of the link
4. To allow multiple Layer 3 protocols to operate over the same physical link
Which feature provides a straightforward "one-touch" device lockdown for configuring the security posture of routers?
1. SSH
2. SDM
3. Autosecure
4. SNMP
What is the function of the Protocol field in a PPP frame?
1. It identifies the application layer protocol that will process the frame
2. It identifies the transport layer protocol that will process the frame
3. It identifies the data link layer protocol encapsulation in the frame's Date field
4. It identifies the network layer protocol encapsulated in the frame's Data field
Why are Frame Relay paths referred to as virtual?
1. There are no dedicated circuits to and from the Frame Relay carrier
2. Frame Relay PVCs re created and discarded on demand
3. The connections between PVC endpoints act like dialup circuits
4. There are no dedicated circuits inside the frame Relay carrier cloud
