The ports cannot communicate with other ports.

The ports default back to the management VLAN.

The ports automatically become a part of VLAN1.

The ports remain a part of that VLAN until the switch is rebooted. They then become members of the management VLAN.

RIP uses hop count and bandwidth as the metric for path selection and sendsupdates periodically.

OSPF is a Cisco proprietary protocol that sends updates triggered by topology changes.

EIGRP uses DUAL to calculate the shortest path and can be configured to do unequal cost load balancing.

BGP is a path vector interior routing protocol.

Packet-switched networks are less susceptible to jitter than circuit-switched networks are.

Packet-switched networks can efficiently use multiple routes inside a service provider network.

Packet-switched networks do not require an expensive permanent connection to each endpoint.

Packet-switched networks usually experience lower latency than circuit-switched networks experience.

Classful routing

Router C cannot win a DR election under any circumstances.

If the link for interface 192.168.1.4 goes down, router B will become the new DR.

The highest router ID was most likely determined via an OSPF router-id statement or statements.

If a new router is added with a higher router ID than router D, it will become the DR.

One router is a non-cisco router

They have different autonomous-system numbers

They are using difference sequence numbers

They are sending incorrect hello types

To synchronize equipment speed for sent data

To synchronize and order sequence numbers so data is sent in complete numerical order

To prevent the receiver from being overwhelmed by incoming data

To synchronize window size on the server

To simplify data transfer to multiple hosts

Bounded updates are sent to all routers within an autonomous system.

Partial updates are sent only to routers that need the information.

The updates are sent to all routers in the routing table.

Updates are bounded by the routers in the topology table.

To keep users segregated on separate subnets

To control the amount of bandwidth that is utilized

To keep signals from interfering with each other

To keep traffic secure

Data Link

All username and password information that is sent will be encrypted.

All authentication on the serial link will be accomplished using a two-way handshake.

The Predictor algorithm will be used to compress all packets that are sent and received on the serial link.

The serial link will be closed if the number of received packets at the destination node falls below 90 percent of the packets that are sent.

SSH uses TCP whereas Telnet does not.

SSH encrypts only the username and password when logging in.

SSH encrypts all remote management communications whereas Telnet does not.

SSH sends a clear text message steam which reduces the bandwidth use for management.

The PVC to R1 must be point-to-point.

LMI types must match on each end of a PVC.

The frame relay PVCs cannot be established between Cisco and non-Cisco routers.

The IETF parameter is missing from the frame-relay map ip 10.10.10.1 201 command.
