• Question 1134:

  Which two actions are performed by the Weighted Random Early Detection mechanism? (Choose two.)

  A. It supports protocol discovery.
  B. It guarantees the delivery of high-priority packets.
  C. It can identify different flows with a high level of granularity.
  D. It can mitigate congestion by preventing the queue from filling up.
  E. It drops lower-priority packets before it drops higher-priority packets.
  D. It can mitigate congestion by preventing the queue from filling up.
  E. It drops lower-priority packets before it drops higher-priority packets.

  Weighted Random Early Detection (WRED) is just a congestion avoidance mechanism. WRED drops packets selectively based on IP precedence. Edge routers assign IP precedences to packets as they enter the network. When a packet arrives, the following events occur:

  1. The average queue size is calculated.

  2. If the average is less than the minimum queue threshold, the arriving packet is queued.

  3. If the average is between the minimum queue threshold for that type of traffic and the maximum threshold for the interface, the packet is either dropped or queued, depending on the packet drop probability for that type of traffic.

  4. If the average queue size is greater than the maximum threshold, the packet is dropped.

  WRED reduces the chances of tail drop (when the queue is full, the packet is dropped) by selectively dropping packets when the output interface begins to show signs of congestion (thus it can mitigate congestion by preventing the queue from filling up). By dropping some packets early rather than waiting until the queue is full, WRED avoids dropping large numbers of packets at once and minimizes the chances of global synchronization. Thus, WRED allows the transmission line to be used fully at all times.

  WRED generally drops packets selectively based on IP precedence. Packets with a higher IP precedence are less likely to be dropped than packets with a lower precedence. Thus, the higher the priority of a packet, the higher the probability that the packet will be delivered

• Question 1135:

  Refer to the exhibit.

  

  A secondary route is required on router R1 to pass traffic to the LAN network on R2 if the primary link fails. Which command must be entered to configure the router?

  A. ip route 10.0.2.0 255.255.255.240 10.0.0.7 92
  B. ip route 10.0.2.0 255.255.255.240 10.0.0.6 91
  C. ip route 10.0.2.0 255.255.255.248 null0 93
  D. ip route 10.0.2.0 255.255.255.248 10.0.0.6 91
  D. ip route 10.0.2.0 255.255.255.248 10.0.0.6 91

• Question 1136:

  Refer to the exhibit.

  

  An engineer built a new L2 LACP EtherChannel between SW1 and SW2 and executed these show commands to verify the work. Which additional task allows the two switches to establish an LACP port channel?

  A. Change the channel-group mode on SW2 to auto
  B. Change the channel-group mode on SW1 to desirable.
  C. Configure the interface port-channel 1 command on both switches.
  D. Change the channel-group mode on SW1 to active or passive.
  D. Change the channel-group mode on SW1 to active or passive.

• Question 1137:

  Which guideline helps to create a secure password policy?

  A. restricting password sharing to a very small group
  B. requiring complex, lengthy passwords instead of simple, short ones
  C. forbidding users from storing passwords in a password manager
  D. allowing passwords used by service accounts to never expire
  B. requiring complex, lengthy passwords instead of simple, short ones

  ---

  A strong password policy encourages users to create complex and lengthy passwords, which are more difficult for attackers to guess or crack using brute-force or dictionary attacks. Complex passwords typically include a mix of uppercase and lowercase letters, numbers, and special characters, while longer passwords (12+ characters) increase the difficulty of attacks.

• Question 1138:

  Which two events occur automatically when a device Is added to Cisco DNA Center? (Choose two.)

  A. The device Is assigned to the Global site.
  B. The device Is placed into the Unmanaged state.
  C. The device Is placed into the Provisioned state.
  D. The device Is placed into the Managed state.
  E. The device is assigned to the Local site.
  A. The device Is assigned to the Global site.
  D. The device Is placed into the Managed state.

  ---

  Device in Global Site: When you successfully add, import, or discover a device, Cisco DNA Center places the device in the Managed state and assigns it to the Global site by default. Even if you have defined SNMP server, Syslog server, and NetFlow collector settings for the Global site, Cisco DNA Center does not change these settings on the device.

• Question 1139:

  What is a similarity OM3 and OM4 fiber optical cable?

  A. Both have a 62.5 micron core diameter.
  B. Both have a 50 micron core diameter.
  C. Both have a 100 micron core diameter.
  D. Both have a 9 micron core diameter.
  B. Both have a 50 micron core diameter.

• Question 1140:

  A. personal 10-digit PIN and RSA certificate
  B. complex password and personal 10-digit PIN
  C. password of 8 to 15 characters and personal 12-digit PIN
  D. fingerprint scanning and facial recognition
  A. personal 10-digit PIN and RSA certificate
