Refer to the exhibit.


The switch with the ACL shown in the exhibit has IP address 10.1.4/24 on VLAN 4. It is the default router for 10.1.0/24. A client in VLAN 4 broadcast a DHCP discovery request, and the request arrives on this switch.
What happens?

  1. The ACL processes the packet, and the packet is permitted and then switched.
  2. The switch routes the packet out of VLAN 4 to the VLAN with the DHCP server.
  3. The ACL processes the packet, and the packet is dropped.
  4. The switch floods the broadcast in VLAN 4.

Answer(s): D



For which use case is a basic or standard access control list (ACL) appropriate?

  1. Controlling which devices can access other devices based on the MAC addresses
  2. Controlling which devices can access other devices based on the IP protocol number
  3. Controlling which devices can access other devices based on the IP addresses
  4. Controlling which devices can access other devices based on the source VLAN tag

Answer(s): C

Explanation:

Access control lists (ACLs) enable you to permit or deny packets based on source and destination IP address, IP protocol information, or TCP or UDP protocol information.

A network administrator is completing an In-Service Software Upgrade (ISSU) for an Intelligent Resilient Framework (IRF) virtual devices. The device has two members. Each member has one management module. Member1 is currently the master. The administrator has initiated a rollback time for this upgrade.
When should the administrator accept the upgrade?

  1. After upgrading both members of the IRF virtual device
  2. After checking the new software's ISSU compatibility but before upgrading either member
  3. After upgrading member 1 but before switching over to and upgrading member 2
  4. After upgrading and switching over to member 2 but before upgrading member 1

Answer(s): A

Explanation:

Performing an ISSU for a multi-member IRF fabric ISSU for a multi-member IRF fabric should be performed as per member in two steps: first upgrade a subordinate member, and then upgrade the master and the other subordinate members.

HOTSPOT
Match each characteristic to the connect multicast routing protocol. If both protocols exhibit characteristic, you must select both.

  1. The answer is Exhibit B.

Answer(s): A

Explanation:

*PIM-SM and PIM-DM
Both PIM-SM and PIM-DM use IGMP.
*PIM-SM
PIM Sparse Mode (PIM-SM) explicitly builds unidirectional shared trees rooted at a rendezvous point (RP) per group, and optionally creates shortest-path trees per source.PM-DM does not use RPs:
PIM-DM differs from PIM-SM in two essential ways:
1) There are noperiodic joins transmitted, only explicitly triggered prunes andgrafts.
2) There is no Rendezvous Point (RP).
*PIM-DMMulticast Routing Information Base (MRIB)
This is the multicast topology table, which is typically derived from the unicast routing table, or from routing protocols such as MBGP that carry multicast-specific topology information. PIM-DM uses the MRIB to make decisions regarding RPF interfaces.
