The ncurses-devel package in CentOS 7 had a older version ncurses resulted in compilation error. This DLL will no longer be loaded at the start of every Python process. The previous update incorrectly included 8. It also now correctly installs or upgrades components when the alternate path is required. Patch by Marc Culler of the Tk project.
It will be removed in Python 3. Python 3. This copy is most used on Windows and macOS. This fixes asyncio. Patch by Augusto Goulart and Pablo Galindo. This feature requires a debug build of Python. Previously it returned None if the test class or method was decorated with a skipping decorator. Errors in functions registered with addClassCleanup and addModuleCleanup were not handled correctly in buffered and debug modes. Errors in setUpModule and functions registered with addModuleCleanup were reported in wrong order.
And several lesser bugs. Patch by Wouter Bolsterlee. Previously it was not called for test methods and classes decorated with a skipping decorator. Patch by Bar Harel. Patch by Luca Citi and Erlend E. It turned out to be disruptive for downstream distributors. Dialect is more descriptive.
It has not been true for several years and likely never was. It is now removed and test is unskipped. The main motivation for this line to be removed from the test is that the size of SharedMemory is not ever guaranteed to be the same. It is decided by the platform. Patch by Serhiy Storchaka. Patch by Nikita Sobolev.

When the routers reload, what will happen? Which of the following methods does split horizon use to reduce incorrect routing information?
The network will be sensitive to congestion and must respond quickly to topology changes. EIGRP updates are partial. EIGRP sends a partial routing table update, which includes just routes that have been changed. Which three routing protocols are distance vector routing protocols?
A network administrator is asked to design a new addressing scheme for a corporate network. Presently, there are users at the head office, users at sales, at manufacturing, and 50 at the research site. Which statement defines the correct VLSM addressing map with minimal waste using the What range of networks are summarized by the address and mask, What is a characteristic of a classful routing protocol on the network?
All subnets are seen by all routers. CIDR addresses are advertised. A subnet can be further subnetted down and advertised correctly. Updates received by a router in a different major network have the default mask applied. Assuming that all routes have been discovered by all routers in the network, which address will successfully summarize only the networks that are shown? A network engineer is implementing a network design using VLSM for network After subnetting the network, the engineer has decided to take one of the subnets, What is the maximum number of subnets that can be created from the What are two benefits of implementing a VLSM addressing scheme?
How many addresses will be available for dynamic NAT translation when a router is configured with the following commands? Which two IP addresses could be assigned to the hosts that are shown in the exhibit? What two pieces of information can be determined from the host IP address of The number of bits borrowed for the subnetwork is 5.
The number of usable hosts for each subnetwork is The network address for this host is The broadcast address for this network is Refer to the graphic. A technician is investigating why H1 and H2 cannot communicate. What problem should the technician discover? Sw1 has an incorrect default gateway. H1 and H2 are on different subnetworks.
Sw1 needs an IP address assigned in the same subnetwork. The H2 IP address should be changed to Based on the output of the show ip nat translations command, which kind of address translation is in effect on this router?
A network technician has been asked to implement a hierarchical addressing scheme. Which two statements could describe the hierarchical addressing scheme structure to the technician? A hierarchical addressing structure logically groups networks into smaller subnetworks. A hierarchical network operates most efficiently without a specific address structure. Route summarization will operate efficiently in a hierarchical network without a hierarchical addressing scheme.
A hierarchical addressing structure can simplify network management and improve scalability. An effective hierarchical addressing scheme must begin with a classful network at the distribution layer. Which two statements differentiate between flat and hierarchical networks? In a hierarchical design, the network consists of all Layer 2 devices. In a hierarchical design, a network consists of a single broadcast domain.
The packets will travel via R2-R3. The traffic will be load-balanced between…. What are two characteristics of this protocol? It displays an actual map of the network topology. It offers rapid convergence in large networks. It is beneficial in complex and hierarchically designed networks.
What is the meaning of the highlighted value 2? It is the administrative distance of the routing protocol. It is the value used by the DUAL algorithm to determine the bandwidth for the link. It is the convergence time measured in seconds. Which route will be used to reach this network? The routers are properly configured using a dynamic routing protocol with default settings, and the network is fully converged.
Router A is forwarding data to router E. Which statement is true about the routing path? It is a link-state routing protocol. It uses the DUAL algorithm to insert backup routes into the topology table.
It uses classless routing as the default method on the router. The What mechanism prevents R2 from receiving false update information regarding the.
Choose two. The packets are used to discover neighbors that are connected on an interface. The packets are sent as unicast. The packets require confirmation. The packets are unreliable. The packets are sent in response to hello packets. A set of switches is being connected in a LAN topology. Which STP bridge priority value will make it least likely for the switch to be selected as the root? A network administrator is analyzing the features that are supported by different first-hop router redundancy protocols.
Which statement describes a feature that is associated with HSRP? HSRP uses active and standby routers. It uses ICMP messages in order to assign the default gateway to hosts. It allows load balancing between a group of redundant routers. HSRP is nonproprietary. The graphic shows the following information: Switch S1 the root bridge uses a port that is labeled B to connect to switch S3 on a port labeled D.
S3 is connected to switch S2 on a port labeled A. S2 uses a port labeled C to connect to S1. Refer to the exhibit. What are two results of issuing the displayed commands on S1, S2, and S3? S2 can become root bridge if S1 fails. S2 can become root bridge if S3 fails. S1 will automatically adjust the priority to be the lowest. S3 can be elected as a secondary bridge. S1 will automatically adjust the priority to be the highest. Which statement describes a characteristic of OSPF external routes?
The cost of a type 1 route is always the external cost, regardless of the interior cost to reach that route. The difference between type 1 and type 2 is in the way the cost of the route is being calculated. A type 2 route is always preferred over a type 1 route for the same destination.
By default, how many equal cost routes to the same destination can be installed in the routing table of a Cisco router?
Its topology table contains two feasible successors to the same network. What action will the router take? The best alternative backup route is immediately inserted into the routing table. The router will query neighbors for an alternate route. The DUAL algorithm is recomputed to find an alternate route. The router uses the default route.

It supports IPv6 and IPv4 addressing. It works together with HSRP. What is the function of STP in a scalable network? It combines multiple switch trunk links to act as one logical link for increased bandwidth.
It protects the edge of the enterprise network from malicious activity. It disables redundant paths to eliminate Layer 2 loops. It decreases the size of the failure domain to contain the impact of failures. Which characteristic would most influence a network design engineer to select a multilayer switch over a Layer 2 switch?
What are two features of OSPF interarea route summarization? Route summarization results in high network traffic and router overhead. Routes within an area are summarized by the ABR. Type 3 and type 5 LSAs are used to propagate summarized routes by default.
ABRs advertise the summarized routes into the backbone. Which two conclusions can be derived from the output? There is one feasible successor to network The network The reported distance to network The neighbor Router R1 has two successors to the The last entry in the table shows that network The third entry indicates that the reported distances for network This same entry shows that neighbor The first entry indicates that R1 has only one successor, not two to network What are the only two roles that permit an OSPF router to be configured for summarization?
