• Question 181:

  How does SR policy operate in Segment Routing Traffic Engineering?

  A. An SR policy for color and endpoint is deactivated at the headend as soon as the headend learns a valid candidate path for the policy.
  B. When "invalidation drop" behavior occurs, the SR policy forwarding entry is removed and the router drops all traffic that is steered into the SR policy.
  C. When a set of SID lists is associated with the SR policy designated path, traffic steering is ECMP-based according to the qualified cost of each SID-list.
  D. An active SR policy installs a BSID-keyed entry in the forwarding table to steer the packets that match the entry to the SR policy SID-list.
  D. An active SR policy installs a BSID-keyed entry in the forwarding table to steer the packets that match the entry to the SR policy SID-list.

• Question 182:

  DRAG DROP

  A network engineer is adding an additional 10Gbps link to an existing 2x10Gdps LACP-based LAG to augment its capacity. Network standards require a bundle interface to be taken out of service if one of its member links goes down, and the new link must be added with minimal impact to the production network. Drag and drop the tasks that the engineer must perform from the left into the sequence on the right. Not all options are used.

• Question 184:

  Refer to the exhibit.

  

  RB#

  interface ethernet 2 ip address 192.168.10.30 255.255.255.0 ip router isis isis tag 80 !

  interface ethernet 3 ip address 192.168.10.40 255.255.255.0 ip router isis isis tag 40 !

  RB#

  route-map leak2-1 permit 10 match tag 50 !

  route-map leak2-1 permit 20 match tag 40 !

  A network engineer with an employee ID 4402:98:032 is setting up an IS-IS network with these requirements:

  1. Routes with a tag of 80 and IP prefixes other than 192.168.10.20/24 must be redistributed from Level 1 into Level 2 2. Route leaking must be configured from Level 2 into the Level 1 domain for routes that are tagged with only 50 or 40

  Which configuration must be implemented on RB to meet the requirements?

  A. Remove match tag 40 from route-map leak2-1
  B. Add match tag 80 in route-map leak2-1
  C. Change match tag 80 to match tag 50 in route-map redist1-2
  D. Add match ip address 152 in route-map redist1-2
  D. Add match ip address 152 in route-map redist1-2

  ---

  Explanation

  The requirement is to redistribute routes with a tag of 80 and IP prefixes other than 192.168.10.20/24 from Level 1 into Level 2, and also to configure route leaking from Level 2 into the Level 1 domain for routes that are tagged with only 50 or 40. Option B, "Add match ip address 152 in route-map redist1-2", meets the first requirement as it allows all IP prefixes except for the specified one (192.168.10.20/24) to be redistributed from Level-1 to Level-2 when they have a tag of 80.

• Question 185:

  An engineer working for telecommunication company needs to secure the LAN network using a prefix list.

  Which best practice should the engineer follow when he implements a prefix list?

  A. An engineer must identify the prefix list with a number only.
  B. The final entry in a prefix list must be /32.
  C. An engineer must include only the prefixes for which he needs to log activity.
  D. An engineer must use nonsequential sequence numbers in the prefix list so that he can insert additional entries later.
  D. An engineer must use nonsequential sequence numbers in the prefix list so that he can insert additional entries later.

• Question 186:

  Refer to the exhibit.

  

  RZ# ipv4 access-list peer_acl_1 10 permit ipv4 host 10.10.10.2 any 20 permit ipv4 host 10.10.10.1 any

  ipv4 access-list peer_acl_2 10 permit ipv4 host 10.10.10.6 any mpls ldp session protection duration 30 for peer_acl_2

  RX# ipv4 access-list peer_acl_1 10 permit ipv4 host 10.10.10.2 any 20 permit ipv4 host 10.10.10.5 any

  mpls ldp session protection duration 60 for peer_acl_1

  The radio network and packet core are using the route RX-RZ-RB to establish communication. The LDP session between 10.10.10.5 and 10.10.10.1 is experiencing link flapping at random intervals for 30-45 seconds each time. A network engineer must protect the LDP session and improve MPLS traffic convergence.

  Which action meets these requirements?

  A. Configure peer_acl_2 on RX and allow IP address 10.10.10.6 in LDP.
  B. Attach peer_acl_1 in for session protection duration 1 on RX.
  C. Add session protection duration 60 for peer_acl_1 under the MPLS LDP instance on RZ.
  D. Enable IGP-LDP sync on RZ and RX.
  C. Add session protection duration 60 for peer_acl_1 under the MPLS LDP instance on RZ.

  C. It uses the pull model to send requested data to a client when polled.
  D. It uses the push model to stream data to desired destinations.
  D. It uses the push model to stream data to desired destinations.
