Which two impacts of adding the IP event dampening feature to a network design are true? (Choose two.)

  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.

took the test last week, i did have about 15 - 20 word for word from this site on the test. (only was able to cram 600 of the questions from this site so maybe more were there i didnt review) had 4 labs, bgp, lacp, vrf with tunnels and actually had to skip a lab due to time. lots of automation syntax questions.

question #50 and question #81 are exactly the same questions, azure site recovery provides________for virtual machines. the first says that it is fault tolerance is the answer and second says disater recovery. from my research, it says it should be disaster recovery. can anybody explain to me why? thank you

answer to this question "what administrative safeguards should be implemented to protect the collected data while in use by manasa and her product management team? " it should be (c) for the following reasons: this administrative safeguard involves controlling access to collected data by ensuring that only individuals who need the data for their job responsibilities have access to it. this helps minimize the risk of unauthorized access and potential misuse of sensitive information. while other options such as (a) documenting data flows and (b) conducting a privacy impact assessment (pia) are important steps in data protection, implementing a "need to know" access policy directly addresses the issue of protecting data while in use by limiting access to those who require it for legitimate purposes. (d) is not directly related to safeguarding data during use; it focuses on data transfers and location.

password lockout being the correct answer for question 37 does not make sense. it should be geofencing.
