CCIE 400-101 Layer 2 Technologies Q153

14.03.2017 16:19, sazan:

the answer is wrong: If an interface is enabled for portfast receives BPDU, the port goes through the spanning-tree listening, learning and forwarding states.

If portfast is enabled, the port doesnt go through the stp states it imidiatly goes in forwarding state which is used on ports where end devices are connected.

CCNA 200-125 WAN Technologies Q264

mistake 08.03.2017 12:19, marcelk84:

The advantages of leased lines include:
+ Simplicity: Point-to-point communication links require minimal expertise to install and maintain.<==== So ANswer: Leased lines require little installation and maintenance expertise. IS CORRECT !!!


+ Quality: Point-to-point communication links usually offer high service quality, if they have adequate bandwidth.
The dedicated capacity removes latency or jitter between the endpoints. <====== So Answer: Leased lines with sufficient bandwidth can avoid latency between endpoints. IS CORRECT!!!!!


+ Availability: Constant availability is essential for some applications, such as e-commerce. Point-to-point communication links provide permanent, dedicated capacity, which is required for VoIP or Video over IP.

The disadvantages of leased lines include:
+ Cost: Point-to-point links are generally the most expensive type of WAN access. The cost of leased line solutions can become significant when they are used to connect many sites over increasing distances. In addition, each endpoint requires an interface on the router, which increases equipment costs.
+ Limited flexibility: WAN traffic is often variable, and leased lines have a fixed capacity, so that the bandwidth of the line seldom matches the need exactly <======== therefore answer D IS NOT CORRECT).

Any change to the leased line generally requires a site visit by ISP personnel to adjust capacity.

hich statement about the spanning-tree portfast feature on the switch is true?
A. If an interface is enabled for portfast receives BPDU, the port is shut down immediately.

B. If an interface is enabled for portfast receives BPDU, the port does not go through the spanning-tree listening, learning, and forwarding states.

C. If an interface is enabled for portfast receives BPDU, the port goes into the spanning-tree inconsistent state.

D. If an interface is enabled for portfast receives BPDU, the port goes through the spanning-tree listening, learning and forwarding states.

?,C:
TCP starvation/UDP dominance likely occurs if (TCP-based) Mission-Critical Data is assigned to the same service-provider class as (UDP-based) Streaming-Video and the class experiences sustained congestion. Even if WRED is enabled on the service-provider class, the same behavior would be observed because WRED (for the most part) manages congestion only on TCP-based flows.

CCDA 200-310 Considerations for Expanding an Existing Network Q388

mistake 06.10.2016 18:55, nic-k: Cisco virtualization Techniques - suppl. info.

Also:
Due to various Cisco litterature the Cisco "VSS" (Virtual Switching System) virtualization Technology should be considered as a Logical Cisco "DEVICE" virtualization Technique - Just like the "VDC" Logical Cisco "DEVICE" virtualization Technique!
Thus the suggested correct "VDC" and "VSS" answers appears to be WRONG within this Question!
(The Q text indeed asks for types of logical "NETWORK" virtualization Techniques!) - Ok!?

Try it with the real switches: set manual half duplex from one side and full from other... You see CRC error but link will be UP and work..
Port security or BPDU guard can put interface into err-disable state...

CCNA 200-125 LAN Switching Technologies Q244

04.09.2016 20:28, murshid.cse: err-disabled state

There are various reasons for the interface to go into errdisable. The reason can be:
Duplex mismatch
Port channel misconfiguration
BPDU guard violation
UniDirectional Link Detection (UDLD) condition
Late-collision detection
Link-flap detection
Security violation
Port Aggregation Protocol (PAgP) flap
Layer 2 Tunneling Protocol (L2TP) guard
DHCP snooping rate-limit
Incorrect GBIC / Small Form-Factor Pluggable (SFP) module or cable
Address Resolution Protocol (ARP) inspection
Inline power


it will be::A (correct)
