  NAT policies perform address translation by translating internal IP addresses to the addresses in a NAT pool.

  The Pool indicates the public addresses you will use to go out the internet. The access list includes the private subnet you will be NATing.

• Question 525:

  Which IPv6 address block forwards packets to a multicast address rather than a unicast address?

  A. 2000::/3
  B. FC00::/7
  C. FE80::/10
  D. FF00::/12
  D. FF00::/12

  ---

  In IPv6, multicast addresses are used to send a single packet to multiple hosts simultaneously. The IPv6 address block that forwards packets to a multicast address rather than a unicast address is the FF00::/8 address block.

• Question 526:

  Which network action occurs within the data plane?

  A. compare the destination IP address to the IP routing table.
  B. run routing protocols (OSPF, EIGRP, RIP, BGP)
  C. make a configuration change from an incoming NETCONF RPC
  D. reply to an incoming ICMP echo request
  A. compare the destination IP address to the IP routing table.

  ---

  Extracted from Book #2, page 359:

  "... the following list details some of the more common actions that a networking device does that fit into the data plane:

  De-encapsulating and re-encapsulating a packet in a data-link frame (routers, layer 3 switches).

  Adding or removing an 802.1Q trunking header (routers and switches).

  Matching an ethernet frame's destination MAC address to the MAC address table (layer 2 switches).

  Matching an IP packet's destination IP address to the IP routing table (routers, layer 3 switches).

  Encrypting the data and adding a new IP header (for VPN processing).

  Changing the source or destination IP address (for NAT) processing).

  Discarding a message due to a filter (ACLs, port security).

  All the items in the list make up the data plane, because the data plane includes all actions done per message."

  Topology

  

  Tasks

  Refer to the topology. All physical cabling is in place. Routers 2 and 3 are inaccessible. Configure OSPF routing for the network and ensure R1 has joined Area 0 without using network statements.

  Task 1

  Configure OSPF on R1 with a process ID and router-ID only as follows:

  -use process ID 30

  -use E0/0 IP as the router ID

  Task 2 Configure R1 to establish neighbor adjacencies with R2 and R3. The network statement under the OSPF process must not be used. Configure R1 to always become the DR for Area 0

  Explanation

  Task 1: Configure OSPF on R1 with Process ID and Router-ID

  You need to configure R1 with an OSPF process ID of 30 and use the IP address of the E0/0 interface as the router ID.

  R1 Configuration:

  R1(config)# router ospf 30

  R1(config-router)# router-id 10.0.12.1 # Assuming this is the IP on E0/0

  Task 2: Establish Neighbor Adjacencies and Set R1 as the DR

  To establish adjacencies between R1 and R2/R3 without using network statements, you need to configure OSPF directly on the relevant interfaces and make sure that R1 becomes the Designated Router (DR) by setting its OSPF priority to the highest possible value.

  R1 Interface Configurations:

  # Configure OSPF on the E0/0 interface

  R1(config)# interface Ethernet0/0

  R1(config-if)# ip ospf 30 area 0

  R1(config-if)# ip ospf priority 255 # Ensure R1 is the DR on this interface

  # Configure OSPF on the E0/1 interface

  R1(config)# interface Ethernet0/1

  R1(config-if)# ip ospf 30 area 0

  R1(config-if)# ip ospf priority 255 # Ensure R1 is the DR on this interface

  router ospf 30: Starts OSPF with process ID 30.

  router-id 10.0.12.1: Sets the router ID to the IP address of E0/0.

  ip ospf 30 area 0: Configures OSPF on the interfaces without using network statements.

  ip ospf priority 255: Ensures that R1 becomes the DR by assigning the highest possible priority (255) on both interfaces, making it the most preferred DR candidate in the election process.

  By configuring R1 in this way, it will establish OSPF adjacencies with R2 and R3, and it will always be elected as the DR for Area 0.

• Question 528:

  Refer to the exhibit.

  

  A network engineer must provide configured IP addressing details to investigate a firewall rule Issue. Which subnet and mask Identify what is configured on the en0 interface?

  A. 10.8.0.0/16
  B. 10.8.64.0/18
  C. 10.8.128.0/19
  D. 10.8.138.0/24
  C. 10.8.128.0/19

• Question 529:

  Which HTTP status code is returned after a successful REST API request?

  A. 200
  B. 301
  C. 404
  D. 500
  A. 200

  ---

  In HTTP (Hypertext Transfer Protocol), status codes are used to indicate the outcome of a request. When a client (such as a web browser) makes a request to a server (such as a web server), the server responds with a status code and a message.

  A successful REST API request typically returns a status code of 200 (OK). This indicates that the request was successful and that the server was able to process it and provide a response.

  Here are some other common HTTP status codes:

  301 (Moved Permanently): This status code indicates that the requested resource has been permanently moved to a new location.

  404 (Not Found): This status code indicates that the requested resource could not be found.

  500 (Internal Server Error): This status code indicates that an error occurred on the server while processing the request.

  In summary, the HTTP status code returned after a successful REST API request is 200 (OK).

• Question 530:

  Refer to the exhibit.

  

  A network engineer must block access for all computers on VLAN 20 to the web server via HTTP All other computers must be able to access the web server.

  

  Which configuration when applied to switch A accomplishes this task?

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

  This ACL denies all TCP traffic from any host to 10.30.0.100 via port 80. The web server goes off of port 80. So this statement blocks ALL traffic going to IP address 10.30.0.100 to the web sever.

  But we only want vlan 20 to be blocked, and NOT anyone else. So this seems wrong. But look at what vlan they are applying it to, in answer "D". Although the ACL is blocking all traffic going to the web server. It is ONLY APPLIED to vlan 20 specifically. So although it blocks all traffic, it only effects vlan 20 members, because that is the only place it is applied to. And as for answer "A", you would think this would be right as well, because the ACL that is applied in this statement, is to the same vlan.

  However, with deny statements in ACL's, if left at the end, will end up just denying any other traffic. you need to add permit statements AFTER deny statements to allow other traffic. If the permit statements are added before the deny statement, when the ACL is implemented, it will just deny all other traffic.
