  1. It switches traffic immediately after a link failure
  2. It improves overall network stability
  3. It speeds up link failure detection
  4. It protects against routing loops
  5. It reduces the utilization of system processing resources

Answer(s): B,E

You have been asked to design a high-density wireless network for a university campus. Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)

  1. Choose a high minimum data rate to reduce the duty cycle.
  2. Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.
  3. Enable 802.11n channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.
  4. Increase the number of SSIDs to load-balance the client traffic.
  5. Implement a four-channel design on 2.4 GHz to increase the number of available channels.

Answer(s): A,B



Which optimal use of interface dampening on a fast convergence network design is true?

  1. when the switch hardware is faster than the debounce timer down detection
  2. when numerous adjacent flaps of very short duration occur
  3. when occasional flaps of long duration occur
  4. when the router hardware is slower than the carrier delay down detection

Answer(s): B

Explanation:

-Interface dampening is a feature that can be used to prevent routing loops in a network. It does this by delaying the re-announcement of a route after a link failure. This prevents the routing protocol from oscillating between two routes, which can cause routing loops.
-Numerous adjacent flaps of very short duration can occur due to a variety of reasons, such as:
-A faulty cable
-A loose connection
-A power outage
-A software bug
-When these flaps occur, it can cause the routing protocol to oscillate between two routes, which can lead to routing loops.
-Interface dampening can help to prevent routing loops by delaying the re-announcement of a route after a link failure. This gives the routing protocol time to determine if the link failure is permanent or temporary.
The other options are not as optimal for use with interface dampening.

-When the switch hardware is faster than the debounce timer down detection does not require interface dampening.
-When occasional flaps of long duration occur can be handled by the routing protocol without the need for interface dampening.
-When the router hardware is slower than the carrier delay down detection does not require interface dampening.

A healthcare customer requested that SNMP traps must be sent over the MPLS Layer 3 VPN service. Which protocol must be enabled?

  1. syslog
  2. SNMPv3
  3. SNMPv2
  4. syslog TLS
  5. SSH

Answer(s): B

Explanation:

-SNMPv3 is a security-enhanced version of SNMP that provides authentication, encryption, and message integrity. This makes it the most secure option for sending SNMP traps over an MPLS Layer 3 VPN service.
-SNMPv2 does not provide any security features, so it is not a secure option for sending SNMP traps over an MPLS Layer 3 VPN service.
-Syslog is a protocol for sending log messages, but it does not provide any security features.
-Syslog TLS is a secure version of syslog that uses Transport Layer Security (TLS) to encrypt the log messages. However, it is not as secure as SNMPv3, as it does not provide message integrity.
-SSH is a secure protocol for remote login, but it is not used for sending SNMP traps.

the correct answer to q8 is b. explanation since the mule app has a dependency, it is necessary to include project modules and dependencies to make sure the app will run successfully on the runtime on any other machine. source code of the component that the mule app is dependent of does not need to be included in the exported jar file, because the source code is not being used while executing an app. compiled code is being used instead.
