What is an important difference between OSPF and IS-IS?

  1. OSPF runs directly on IP, while IS-IS runs directly on Ethernet.
  2. OSPF is a link state protocol, while IS-IS is a distance vector protocol.
  3. OSPF runs directly on Ethernet, while IS-IS runs directly on IP.
  4. OSPF is a distance vector protocol, while IS-IS is a link state protocol.

Answer(s): A

Explanation:

OSPF runs directly on IP, while IS-IS runs directly on Ethernet. This means that OSPF uses IP addresses to identify routers and links, while IS-IS uses MAC addresses or other link-layer identifiers. OSPF also requires an IP header for each packet, while IS-IS does not. Both OSPF and IS-IS are link state protocols, which means that they flood information about the network topology to all routers in the same area or domain.

What is the subnet address for 10.57.126.156/29?

  1. 10.57.126.152
  2. 10.57.126.144
  3. 10.57.126.0
  4. 10.57.126.156

Answer(s): A

Explanation:

The subnet address for 10.57.126.156/29 is 10.57.126.152. To find the subnet address, we need to perform a bitwise AND operation between the IP address and the subnet mask. The subnet mask for /29 is 255.255.255.248, which in binary is 11111111.11111111.11111111.11111000. The IP address in binary is 00001010.00111001.01111110.10011100. The result of the AND operation is 00001010.00111001.01111110.10011000, which in decimal is 10.57.126.152.

For IP destinations not found in the IS-IS Level 1 database, the Level 1 router must forward packets to the nearest Level 1-Level 2 router with which set?

  1. options bit
  2. status bit
  3. attach bit
  4. overload bit

Answer(s): C

Explanation:

For IP destinations not found in the IS-IS Level 1 database, the Level 1 router must forward packets to the nearest Level 1-Level 2 router with the attach bit set. The attach bit is a flag in the IS-IS Level 1 LSP that indicates that the router is also a Level 2 router and can reach destinations outside the Level 1 area. The Level 1 router will install a default route pointing to the nearest Level 1-Level 2 router with the attach bit set. This way, the Level 1 router can forward packets to other areas without having to maintain a full Level 2 database.
