NEW QUESTION 83
Which list defines the contents of an MPLS label?
- A. 32-bit label; 3-bit traffic class; 1-bit bottom stack; 8-bit TTL
- B. 32-bit label; 3-bit flow label; 1-bit bottom stack; 8-bit hop limit
- C. 20-bit label; 3-bit traffic class; 1-bit bottom stack; 8-bit TTL
- D. 20-bit label; 3-bit flow label; 1-bit bottom stack; 8-bit hop limit
Answer: C
Explanation:
The first 20 bits constitute a label, which can have 2^20 values. Next comes 3 bit value called Traffic Class. It was formerly called as experimental (EXP) field. Now it has been renamed to Traffic Class (TC). This field is used for QoS related functions. Ingress router can classify the packet according to some criterion and assign a 3 bit value to this filed. If an incoming packet is marked with some IP Precedence or DSCP value and the ingress router may use such a field to assign an FEC to the packet. Next bit is Stack bit which is called bottom-of-stack bit. This field is used when more than one label is assigned to a packet, as in the case of MPLS VPNs or MPLS TE. Next byte is MPLS TTL field which serves the same purpose as that of IP TTL byte in the IP header
NEW QUESTION 84
In which two ways does the IPv6 First-Hop Security Binding Table operate? (Choose two.)
- A. by IPv6 HSRP to make sure neighbors are authenticated before being used as gateways
- B. by the recovery mechanism to recover the binding table in the event of a device reboot
- C. by storing hashed keys for IPsec tunnels for the built-in IPsec features
- D. by IPv6 routing protocols to securely build neighborships without the need of authentication
- E. by various IPv6 guard features to validate the data link layer address
Answer: B,E
Explanation:
Overview of the IPv6 First-Hop Security Binding Table
A database table of IPv6 neighbors connected to the device is created from information sources such as NDP snooping. This database, or binding table, is used by variousIPv6 guard features to validate the link-layer address (LLA), the IPv4 or IPv6 address, and the prefix binding of the neighbors to prevent spoofing and redirect attacks.
IPv6 First-Hop Security Binding Table Recovery MechanismThe IPv6 first-hop security binding table recovery mechanism enables the binding table to recover in the event of a device reboot.

Refer to the exhibit.
An IP SLA is configured to use the backup default route when the primary is down, but it is not working as desired. Which command fixes the issue?
- A. R1(config)# ip route 0.0.0.0.0.0.0.0.1.1.1.1 track 1
- B. R1(config)#ip sla track 1

- D. R1(config)# ip route 0.0.0.0.0.0.0.0.2.2.2.2 10 track 1
Answer: A
Explanation:
Reference:
Note: By default Static Router AD value-1 hence ip route 0.0.0.0. 0.0.0.0. 1.1.1.1 track 1 means AD-1 which must be less than of back up route AD.
Define the backup route to use when the tracked object is unavailable.
!--- The administrative distance of the backup route must be greater than
!--- the administrative distance of the tracked route.
!--- If the primary gateway is unreachable, that route is removed
!--- and the backup route is installed in the routing table
!--- instead of the tracked route.

Same Answer is already updated below:
HTTP and HTTPs run on TCP port 80 and 443, respectively and we have to remember them.
Syslog runs on UDP port 514 while NTP runs on UDP port 123 so if we remember them we can find out the matching answers easily. But maybe there is some typos in this question as 2001:d88:800:200c::c/126 only ranges from 2001:d88:800:200c:0:0:0:c (4 hosts in total). It does not cover host 2001:0D88:0800:200c::1f. Same for , which also ranges from
2001:d88:800:200c:0:0:0:c to 2001:d88:800:200c:0:0:0:f and does not cover host 2001:0D88:0800:200c::1c

NEW QUESTION 96
Drag and drop the packet types from the left onto the correct descriptions on the right.
Answer:
Explanation:
Explanation
Unlike legacy network technologies such as ISDN, Frame Relay, and ATM that defined separate data and control channels, IP carries all packets within a single pipe. Thus, IP network devices such as routers and switches must be able to distinguish between data plane, control plane, and management plane packets to treat each packet appropriately.From an IP traffic plane perspective, packets may be divided into four distinct, logical groups:1. Data plane packets - End-station, user-generated packets that are always forwarded by network devices to other end-station devices. From the perspective of the network device, data plane packets always have a transit destination IP address and can be handled by normal, destination IP address-based forwarding processes.2. Control plane packets - Network device generated or received packets that are used for the creation and operation of the network itself. From the perspective of the network device, control plane packets always have a receive destination IP address and are handled by the CPU in the network device route processor. Examples include protocols such as ARP, BGP, OSPF, and other protocols that glue the network together.3. Management plane packets - Network device generated or received packets, or management station generated or received packets that are used to manage the network. From the perspective of the network device, management plane packets always have a receive destination IP address and are handled by the CPU in the network device route processor. Examples include protocols such as Telnet, Secure Shell (SSH), TFTP, SNMP, FTP, NTP, and other protocols used to manage the device and/or network.4. Services plane packets - A special case of data plane packets, services plane packets are also user-generated packets that are also forwarded by network devices to other end-station devices, but that require high-touch handling by the network device (above and beyond normal, destination IP address-based forwarding) to forward the packet. Examples of high-touch handling include such functions as GRE encapsulation, QoS, MPLS VPNs, and SSL/IPsec encryption/decryption, etc. From the perspective of the network device, services plane packets may have a transit destination IP address, or may have a receive destination IP address (for example, in the case of a VPN tunnel endpoint).
